The Abbott FreeStyle Libre glucose monitoring system significantly reduced hospitalizations for diabetic ketoacidosis (DKA), diabetes-related emergencies, and all-cause hospitalizations among patients with diabetes, data from two new studies indicate.

The results were presented June 13 during the virtual American Diabetes Association (ADA) 80th Scientific Sessions.

One large database analysis, from France, revealed that use of the Libre system halved hospitalization rates for DKA among people with type 1 or type 2 diabetes.

In the other study, a retrospective analysis of data from over 1200 insulin-treated individuals with type 2 diabetes in the United States, use of the Libre was associated with significant reductions in both hospitalizations for acute diabetes-related emergency events and all-cause hospitalizations.

The Libre system reads glucose levels through a sensor worn on the back of the upper arm for up to 14 days. Users wave a scanner over the device to obtain a reading.

Asked to comment, Nicholas Argento, MD, diabetes technology director at Maryland Endocrine and Diabetes, Columbia, told Medscape Medical News: “One of the biggest problems with access to continuous glucose monitoring is cost. Payers need to see that there’s some cost-saving to offset the cost of paying for these devices. I think both of these studies are important for that reason.”

However, Argento also said he recommends that people with type 1 diabetes use the Dexcom continuous glucose monitor (CGM) if possible rather than the Libre, despite the former’s higher cost, because it has an alarm feature that the Libre doesn’t and is more accurate in the hypoglycemic range.

Large French study: Libre cuts DKA hospitalizations by 50%

The FreeStyle Libre system has been reimbursed in France since June 1, 2017 for patients over 4 years of age with type 1 or type 2 diabetes who take at least 3 insulin injections per day or use an insulin pump.

The new results were presented by Ronan Roussel, MD, PhD, chief of the endocrinology, diabetes, and nutrition department at Hôpital Bichat, Fédération de Diabétologie, AP-HP, Paris, France.

The DKA hospitalization data Roussel reported were part of a larger longitudinal retrospective cohort study looking at overall prescribing and use of the Libre system, and its impact on healthcare outcomes and associated costs in standard practice in France. The data came from a large nationwide claims database containing all healthcare expenses for over 66 million people.

The current study participants were 74,076 individuals with at least a full year of follow-up beginning in 2017 with the date of first reimbursement for the FreeStyle Libre system. Of those, 44.8% (33,203) had type 1 diabetes and 55.2% (40,955) had type 2 diabetes.

Prior to initiation of Libre use, about a quarter of each group was using 0 fingerstick test strips per day, about 19% of the type 1 diabetes group and 28% of the type 2 diabetes group were using 1-3 strips per day, and about half of both groups were using 4 or more strips per day.

Compared with the year prior to the date of first reimbursement for the Libre, hospitalization rates for DKA during the first year of Libre use fell by 52% in the type 1 diabetes group, from 5.46 to 2.59 per 100 patient-years, and by 47% in the type 2 diabetes group, from 1.70 to 0.90 per 100 patient-years.

The impact of Libre on DKA hospitalizations was most dramatic among those not using any test strips prior to Libre use, with a 60% reduction for the type 1 diabetes group (8.31 to 3.31 per 100 patient-years) and a 51% reduction in the type 2 diabetes group (2.51 to 1.23 per 100 patient-years).

But interestingly, the next-biggest impact was among those who had been using more than 5 test strips per day, with drops of 59% among those with type 1 diabetes (5.55 to 2.26 per 100 patient-years) and 52% in the type 2 diabetes group (1.88 to 0.90 per 100 patient-years).

This finding is important for the United States, Argento said, because some insurers, including Medicare, require that the patient performs at least 4 fingerstick glucose measurements per day to qualify for reimbursement for the Libre or any CGM system.

“I think that speaks to the importance of not requiring that patients first show they’re frequently doing self-blood glucose monitoring before they can get these devices,” he observed.

The large benefit in the high strip use group is interesting too, Argento said. “It’s a different group of people. They’re more engaged in their care...This U-shaped curve they showed is fascinating.”

Reductions in DKA hospitalizations were also similar between patients using insulin pumps and those using multiple daily injections of insulin, Roussel reported.

“It is plausible that use of the FreeStyle Libre system allowed people to detect and limit persistent hyperglycemia, and subsequently ketoacidosis,” Roussel said.

“This analysis has significant implications for patient-centered clinical care in diabetes and also for long-term health economic outcomes in the treatment of diabetes at a national level.”

All-cause hospitalizations drop 30% with Libre in type 2 diabetes

Richard M. Bergenstal, MD, executive director of the International Diabetes Center at Park Nicollet, Minneapolis, Minnesota, presented the US results, obtained from the IBM Watson Health MarketScan, a database of commercial and Medicare supplemental insurance claims for over 30 million Americans.

The study population included 2463 patients with type 2 diabetes using basal-bolus daily insulin injections but who had not previously used Libre or any other CGM, and for whom data were available 6 months prior to and after Libre initiation.

Compared with 6 months prior to Libre use, the number of acute diabetes-related events — including hyperglycemia, hypoglycemia, DKA, hypoglycemic coma, and hyperosmolarity — in the subsequent 6 months dropped by 60%, from 0.180 to 0.072 events per patient-year (P < .001).

Similarly significant reductions were seen between males and females, and among those aged ≥ 50 years or < 50 years.

All-cause hospitalizations also significantly dropped by 33% (P < 0.001), from 0.420 to 0.283 events per patient-year. Among diagnostic codes for the hospitalizations, circulatory system causes remained number one during both time periods, with little change from pre-Libre to during Libre use.

However, “endocrine, nutritional, and metabolism system” codes dropped from the second position pre-Libre (6.4 events/100 patient-years) down to the fifth position (2.6 events/100 patient-years).

And, Bergenstal noted, other major diagnostic categories that also dropped included respiratory (3.5 to 2.1 events/100 patient-years), kidney and urinary tract (3.3 to 1.7 events/100 patient-years), and hepatobiliary system and pancreas (2.4 to 1.4 events/100 patient-years).

“We’re seeing a resurgence of certain types of complications, but all of these were reduced in the 6 months after Libre,” Bergenstal pointed out.

And, pertinent to the current COVID-19 situation, “infectious and parasitic disease and disorders” dropped as well, from 4.8 to 2.8 per 100 patient-years.

Argento commented: “The fact that infections went down speaks to something that is important right now. Hyperglycemia impairs immune function chronically, but also acutely...so patients who become ill and their blood glucose deteriorates rapidly are much more likely to have a poor outcome regardless of infection. There are data for COVID-19 now.”

“These findings provide compelling support for use of [Libre] to improve both clinical outcomes and potentially reduce costs in this patient population,” Bergenstal concluded.

Roussel has reported being on advisory panels for Abbott, AstraZeneca, Diabnext, Eli Lilly, Merck, Mundipharma International, Novo Nordisk, and Sanofi-Aventis. Bergenstal has reported being a consultant for Ascensia Diabetes Care, Johnson & Johnson, and has other relationships with Abbott, Dexcom, Hygieia, Lilly Diabetes, Medtronic, Novo Nordisk, Onduo, Roche Diabetes Care, Sanofi, and UnitedHealth Group. Argento has reported consulting and being on speaker bureaus for Omnipod, Eli Lilly, Novo Nordisk, Dexcom, and Boehringer Ingelheim.

Drug adherence, healthcare use, medical costs, and heart failure rates were better among patients with type 2 diabetes who were newly prescribed a sodium-glucose cotransporter 2 (SGLT2) inhibitor than a glucagon-like peptide 1 (GLP-1) receptor agonist in a real-world, observational study.

Composite cardiovascular (CV) outcomes were similar between the two drug classes.

Insiya Poonawalla, PhD, a researcher at Humana Healthcare Research, Flower Mound, Texas, reported the study results in an oral presentation on June 12 at the virtual American Diabetes Association (ADA) 80th Scientific Sessions.

The investigators matched more than 10,000 patients with type 2 diabetes — half initiated on an SGLT2 inhibitor and half initiated on a GLP-1 agonist — from the Humana database of insurance claims data.

“These findings suggest potential benefits” of SGLT2 inhibitors, “particularly where risk related to heart failure is an important consideration,” Poonawalla said, but as always, any benefits need to be weighed against any risks.

And “while this study provides a pretty complete and current picture of claims until 2018,” it has limitations inherent to observational data (such as possible errors or omissions in the claims data), she conceded.

Mitchel L. Zoler/MDedge News

Mikhail Kosiborod, MD, invited to comment on the research, said this preliminary study was likely too short and small to definitively demonstrate differences in composite CV outcomes between the two drug classes, but he noted that the overall findings are not unexpected.

And often, the particular CV risk profile of an individual patient will point to one or the other of these drug classes as a best fit, he noted.

Too soon to alter clinical practice

Kosiborod, from Saint Luke’s Mid America Heart Institute, Kansas City, Missouri, said he nevertheless feels “it would be a bit premature to use these findings as a guide to change clinical practice.”

“The study is relatively small in scope and likely underpowered to examine CV outcomes,” he said in an email interview.

Larger population-based studies and ideally head-to-head randomized controlled trials of various type 2 diabetes agents could compare these two drug classes more definitively, he asserted.

In the meantime, safety profiles of both medication classes “have been well established — in tens of thousands of patients in clinical trials and millions of patients prescribed these therapies in clinical practice,” he noted.

In general, the drugs in both classes are well-tolerated and safe for most patients with type 2 diabetes when used appropriately.

“Certainly, patients with type 2 diabetes and established CV disease (or at high risk for CV complications) are ideal candidates for either an SGLT2 inhibitor or a GLP-1 receptor agonist,” Kosiborod said.

“Given the data we have from outcome trials, an SGLT2 inhibitor would be a better initial strategy in a patient with type 2 diabetes and heart failure (especially heart failure with reduced ejection fraction) and/or diabetic kidney disease,” he continued.

On the other hand, “a GLP-1 receptor agonist may be a better initial strategy in a type 2 diabetes patient with (or at very high risk for) atherosclerotic cardiovascular disease (ASCVD), especially if there is concomitant obesity contributing to the disease process.”

Limited comparisons of these two newer drug classes

“Real-world evidence comparing these two therapeutic classes based on CV outcomes is limited,” Poonawalla said at the start of her presentation, and relative treatment persistence, utilization, and cost data are even less well studied.

To investigate this, the researchers identified patients aged 19 to 89 years who were newly prescribed one of these two types of antidiabetic agents during January 1, 2015 through June 30, 2017.

Poonawalla and senior study author Phil Schwab, PhD, research lead, Humana Healthcare Research, Louisville, Kentucky, clarified the study design and findings in an email to this new organization.

The team matched 5507 patients initiated on a GLP-1 agonist with 5507 patients newly prescribed an SGLT2 inhibitor.

Patients were a mean age of 65 years and 53% were women.

More than a third (37%) had established ASCVD, including myocardial infarction (MI) (7.9%) and stroke (9.8%), and 11.5% had heart failure.

About two thirds were receiving metformin and about a third were receiving insulin.

In the GLP-1 agonist group, more than half of patients were prescribed liraglutide (57%), followed by dulaglutide (33%), exenatide, and lixisenatide (two patients).

In the SGLT2 inhibitor group, close to 70% received canagliflozin, about a quarter received empagliflozin, and the rest received dapagliflozin.

During up to 3.5 years of follow-up, a similar percentage of patients in each group had either an MI, stroke, or died (the primary composite CV outcome) (hazard ratio [HR], 0.98; 95% CI, 0.89 - 1.07).

However, more patients in the GLP-1 agonist group had heart failure or died (the secondary composite CV outcome), driven by a higher rate of heart failure in this group.

But after adjusting for time to events there was no significant between-group difference in the secondary composite CV outcome (HR, 1.09; 95% CI, 0.99 - 1.21).

During the 12-months after the initial prescription, patients who were started on a GLP-1 agonist versus an SGLT2 inhibitor had higher mean monthly medical costs, which included hospitalizations, emergency department (ED) visits, and outpatient visits ($904 vs $834; P < .001).

They also had higher pharmacy costs, which covered all drugs ($891 vs $783; P < .001).

And they were more likely to discontinue treatment (HR, 1.15; 95% CI, 1.10 - 1.21), be hospitalized (14.4% vs 11.9%; P < .001), or visit the ED (27.4% vs 23.5%; P < .001).

“Not too surprising” and “somewhat reassuring”

Overall, Kosiborod did not find the results surprising.

Given the sample size and follow-up time, event rates were probably quite low and insufficient to draw firm conclusions about the composite CV outcomes, he reiterated.

However, given the comparable effects of these two drug types on major adverse cardiac events (MACE) in similar patient populations with type 2 diabetes, it is not too surprising that there were no significant differences in these outcomes.

It was also “somewhat reassuring” to see that heart failure rates were lower with SGLT2 inhibitors, “as one would expect,” he said, because these agents “have been shown to significantly reduce the risk of hospitalization for heart failure in multiple outcome trials, whereas GLP-1 receptor agonists’ beneficial CV effects appear to be more limited to MACE reduction.”

The higher rates of discontinuation with GLP-1 receptor agonists “is also not a surprise, since patients experience more gastrointestinal tolerability issues with these agents (mainly nausea),” which can be mitigated in the majority of patients with appropriate education and close follow up — but is not done consistently.

Similarly, “the cost differences are also expected, since GLP-1 receptor agonists tend to be more expensive.”

On the other hand, the higher rates of hospitalizations with GLP-1 agonists compared to SGLT2 inhibitors “requires further exploration and confirmation,” Kosiborod said.

But he suspects this may be due to residual confounding, “since GLP-1 agonists are typically initiated later in the type 2 diabetes treatment algorithm,” so these patients could have lengthier, more difficult-to-manage type 2 diabetes with more comorbidities despite the propensity matching.

And “while this study provides a pretty complete and current picture of claims until 2018,” it has limitations inherent to observational data (such as possible errors or omissions in the claims data), she conceded.

Mikhail Kosiborod, MD, invited to comment on the research, said this preliminary study was likely too short and small to definitively demonstrate differences in composite CV outcomes between the two drug classes, but he noted that the overall findings are not unexpected.

And often, the particular CV risk profile of an individual patient will point to one or the other of these drug classes as a best fit, he noted.

Too soon to alter clinical practice

Kosiborod, from Saint Luke’s Mid America Heart Institute, Kansas City, Missouri, said he nevertheless feels “it would be a bit premature to use these findings as a guide to change clinical practice.”

“The study is relatively small in scope and likely underpowered to examine CV outcomes,” he said in an email interview.

Larger population-based studies and ideally head-to-head randomized controlled trials of various type 2 diabetes agents could compare these two drug classes more definitively, he asserted.

In the meantime, safety profiles of both medication classes “have been well established — in tens of thousands of patients in clinical trials and millions of patients prescribed these therapies in clinical practice,” he noted.

In general, the drugs in both classes are well-tolerated and safe for most patients with type 2 diabetes when used appropriately.

“Certainly, patients with type 2 diabetes and established CV disease (or at high risk for CV complications) are ideal candidates for either an SGLT2 inhibitor or a GLP-1 receptor agonist,” Kosiborod said.

“Given the data we have from outcome trials, an SGLT2 inhibitor would be a better initial strategy in a patient with type 2 diabetes and heart failure (especially heart failure with reduced ejection fraction) and/or diabetic kidney disease,” he continued.

On the other hand, “a GLP-1 receptor agonist may be a better initial strategy in a type 2 diabetes patient with (or at very high risk for) atherosclerotic cardiovascular disease (ASCVD), especially if there is concomitant obesity contributing to the disease process.”

Limited comparisons of these two newer drug classes

“Real-world evidence comparing these two therapeutic classes based on CV outcomes is limited,” Poonawalla said at the start of her presentation, and relative treatment persistence, utilization, and cost data are even less well studied.

To investigate this, the researchers identified patients aged 19 to 89 years who were newly prescribed one of these two types of antidiabetic agents during January 1, 2015 through June 30, 2017.

Poonawalla and senior study author Phil Schwab, PhD, research lead, Humana Healthcare Research, Louisville, Kentucky, clarified the study design and findings in an email to this new organization.

The team matched 5507 patients initiated on a GLP-1 agonist with 5507 patients newly prescribed an SGLT2 inhibitor.

Patients were a mean age of 65 years and 53% were women.

More than a third (37%) had established ASCVD, including myocardial infarction (MI) (7.9%) and stroke (9.8%), and 11.5% had heart failure.

About two thirds were receiving metformin and about a third were receiving insulin.

In the GLP-1 agonist group, more than half of patients were prescribed liraglutide (57%), followed by dulaglutide (33%), exenatide, and lixisenatide (two patients).

In the SGLT2 inhibitor group, close to 70% received canagliflozin, about a quarter received empagliflozin, and the rest received dapagliflozin.

During up to 3.5 years of follow-up, a similar percentage of patients in each group had either an MI, stroke, or died (the primary composite CV outcome) (hazard ratio [HR], 0.98; 95% CI, 0.89 - 1.07).

However, more patients in the GLP-1 agonist group had heart failure or died (the secondary composite CV outcome), driven by a higher rate of heart failure in this group.

But after adjusting for time to events there was no significant between-group difference in the secondary composite CV outcome (HR, 1.09; 95% CI, 0.99 - 1.21).

During the 12-months after the initial prescription, patients who were started on a GLP-1 agonist versus an SGLT2 inhibitor had higher mean monthly medical costs, which included hospitalizations, emergency department (ED) visits, and outpatient visits ($904 vs $834; P < .001).

They also had higher pharmacy costs, which covered all drugs ($891 vs $783; P < .001).

And they were more likely to discontinue treatment (HR, 1.15; 95% CI, 1.10 - 1.21), be hospitalized (14.4% vs 11.9%; P < .001), or visit the ED (27.4% vs 23.5%; P < .001).

“Not too surprising” and “somewhat reassuring”

Overall, Kosiborod did not find the results surprising.

Given the sample size and follow-up time, event rates were probably quite low and insufficient to draw firm conclusions about the composite CV outcomes, he reiterated.

However, given the comparable effects of these two drug types on major adverse cardiac events (MACE) in similar patient populations with type 2 diabetes, it is not too surprising that there were no significant differences in these outcomes.

It was also “somewhat reassuring” to see that heart failure rates were lower with SGLT2 inhibitors, “as one would expect,” he said, because these agents “have been shown to significantly reduce the risk of hospitalization for heart failure in multiple outcome trials, whereas GLP-1 receptor agonists’ beneficial CV effects appear to be more limited to MACE reduction.”

The higher rates of discontinuation with GLP-1 receptor agonists “is also not a surprise, since patients experience more gastrointestinal tolerability issues with these agents (mainly nausea),” which can be mitigated in the majority of patients with appropriate education and close follow up — but is not done consistently.

Similarly, “the cost differences are also expected, since GLP-1 receptor agonists tend to be more expensive.”

On the other hand, the higher rates of hospitalizations with GLP-1 agonists compared to SGLT2 inhibitors “requires further exploration and confirmation,” Kosiborod said.

But he suspects this may be due to residual confounding, “since GLP-1 agonists are typically initiated later in the type 2 diabetes treatment algorithm,” so these patients could have lengthier, more difficult-to-manage type 2 diabetes with more comorbidities despite the propensity matching.

Drug adherence, healthcare use, medical costs, and heart failure rates were better among patients with type 2 diabetes who were newly prescribed a sodium-glucose cotransporter 2 (SGLT2) inhibitor than a glucagon-like peptide 1 (GLP-1) receptor agonist in a real-world, observational study.

Composite cardiovascular (CV) outcomes were similar between the two drug classes.

Insiya Poonawalla, PhD, a researcher at Humana Healthcare Research, Flower Mound, Texas, reported the study results in an oral presentation on June 12 at the virtual American Diabetes Association (ADA) 80th Scientific Sessions.

The investigators matched more than 10,000 patients with type 2 diabetes — half initiated on an SGLT2 inhibitor and half initiated on a GLP-1 agonist — from the Humana database of insurance claims data.

For patients with painful diabetic neuropathy that doesn’t resolve with standard treatment, use of a 10-kHz spinal cord stimulation device may relieve pain and improve sensation, initial results of a large randomized controlled trial suggest.

Some 79% of patients had substantial pain relief 3 months after starting treatment, compared with 5% of patients managed with conventional medical treatment, according to results of SENZA-PDN, which investigators say is the largest-ever randomized, controlled trial of spinal cord stimulation for managing painful diabetic neuropathy.

Although this was not a comparative trial, investigator Erika Petersen, MD, said in an interview that results seen with the 10-kHz spinal cord stimulator (Nevro Corp.) exceed what has been seen in previous studies of spinal cord stimulation devices operating at lower frequencies, where response rates have been in the 40%-55% range.

New option for front line providers?

“My overall takeaway here is that these initial 3-month results are very promising,” said Dr. Petersen, who is Director of Functional & Restorative Neurosurgery and Neuromodulation at the University of Arkansas for Medical Sciences in Little Rock.

Patient-perceived numbness and sensory assessments by investigators also improved following implantation of the spinal cord stimulator, according to Dr. Peterson, who added that measurements of sleep and activity also seemed to improve in these patients with painful diabetic neuropathy.

“Spinal cord stimulation has been established for chronic back and leg pain, but being able to innovate in this population with diabetic neuropathy is really something that we anticipate will improve quality of life and functional benefit for a large number of patients who currently have been stuck with the options that are currently available,” Dr. Petersen said in an interview.

Natalie H. Strand, MD, assistant professor of pain medicine at Mayo Clinic, Scottsdale, Ariz., said that while the findings of this randomized study may require corroboration, they do suggest that this neuromodulation device may provide another option for front line diabetes providers when patients have persistent pain despite appropriately medication management.

“These patients are probably under-referred to interventional pain specialists,” said Dr. Strand in an interview. “The primary care physicians and endocrinologists may not think of neuromodulation as an appropriate treatment, and they may not know that it can be so effective.”

“Anything that we can add as physicians to help decrease the burden of diabetes is going to be very impactful,” Dr. Strand added. “While this is focused on pain, what we’re really trying to treat is the entire patient – improve their quality of life and make diabetes more manageable.”

Nearly 80% of treated patients responded at 3 months

The SENZA-PDN study results were presented as a late-breaking poster presentation at the virtual annual scientific sessions of the American Diabetes Association. Those results included 103 patients randomized to conventional medical management alone, and 113 who received medical management plus the spinal cord stimulator, which Dr. Strand described as a minimally invasive, reversibly implanted epidural device designed to stimulate the spinal cord and reverse pain sensations.

The median age was about 61 years and roughly two-thirds were male. All patients had to have lower extremity pain with an average intensity of at least 5 out of 10 cm on the visual analog scale (VAS) at enrollment, according to published inclusion criteria for the study (NCT03228420).

Three months after device implantation, 75 out of 95 evaluable patients (79%) had a response, defined as 50% or greater pain relief plus no worsening of neurological deficit related to painful diabetic neuropathy. By contrast, only 5 of 94 medically managed patients (5%) met those response criteria (P < 0.001), according to reported data.

The mean VAS score in the device group dropped from 7.6 at baseline to 2.4 at 1 month and 1.7 at 3 months, data show. In the medical management group, mean VAS scores were 7.0 at baseline, 6.7 at 1 month, and 6.5 at 3 months.

Sensory assessment of monofilament and pinprick perception, performed by investigators at 3 months, indicated a 72% improvement in the device arm versus 7% improvement in the medical management arm, while analysis of patient-drawn diagrams additionally suggested improvement in perceived numbness, according to investigators.

Quality-of-life improvements related to sleep and activity were also apparent at 3 months in the device group, Dr. Petersen said, with investigators noting substantial reductions in trouble falling asleep because of pain and awakening due to pain. Likewise, data at this initial report suggested improvements in 6-minute walk test that were apparent in the device group but not the medical management group.


While the spinal cord stimulator under investigation is already approved by the U.S. Food and Drug Administration, Dr. Petersen said a lack of data specific to painful diabetic neuropathy has been a hurdle to insurance coverage for some patients.

“I’ve had patients who clearly have every suggestion that they match the characteristics of our research population here, but the insurance will decline the procedure as being experimental,” she said. “My hope is that randomized, controlled trial results in a research study such as this is something that will improve the access of the therapy to patients who would not be able to afford it without having insurance cover the procedure.”

Follow-up of the study will continue for 24 months and will include assessment of health economics and use of pain medication, Dr. Petersen said.

The SENZA-PDN study is funded by Nevro Corp. Dr. Petersen said that she receives research funding and consulting fees from Nevro Corp. and other device manufacturers. Dr. Strand said she had no disclosures related to the research.

Roughly half of adolescents and young adults with either type 1 or type 2 diabetes for about a decade had diastolic dysfunction, a direct precursor to heart failure, in a multicenter echocardiography survey of 479 American patients.

Using tissue Doppler echocardiography findings from 258 adolescents and young adults with type 1 diabetes, and 221 with type 2 diabetes, the study found at least one imaging marker of ventricular stiffness – diastolic dysfunction – in 58% of the patients with type 2 diabetes and in 47% of those with type 1 diabetes. The type 1 patients averaged 21 years of age with a median 12 years of diagnosed disease, while the type 2 patients had an average age of 25 years and a median 11 years disease duration.

The analysis also identified several measures that significantly linked with the presence of diastolic dysfunction: older age, female sex, nonwhite race, type 2 diabetes, higher heart rate, higher body mass index, higher systolic blood pressure, and higher hemoglobin A_1c.

“Our data suggest targeting modifiable risk factors” in these patients in an effort to slow the process causing the diastolic dysfunction, Amy S. Shah, MD, said at the virtual annual scientific sessions of the American Diabetes Association. She particularly cited interventions aimed at reducing body mass index, lowering blood pressure, and improving glycemic control, as well as preventing type 2 diabetes in the first place.

Prevention of type 2 diabetes, as well as prevention of diastolic dysfunction development and progression, are key steps because of the substantial clinical consequences of diastolic dysfunction, triggered by stiffening of the left ventricle. Diastolic dysfunction leads to increased left ventricular diastolic pressure, left atrial dysfunction, and ultimately heart failure with preserved ejection fraction, a common diabetes complication that currently has no treatment with proven efficacy, said Dr. Shah, a pediatric endocrinologist and director of the Adolescent Type 2 Diabetes Program at Cincinnati Children’s Hospital Medical Center.

“It’s very concerning that diastolic dysfunction is so prevalent in this age group,” commented Robert A. Gabbay, MD, Chief Science & Medical Officer of the American Diabetes Association. “An important question is whether you can see an improvement by reversing risk factors.” He noted the importance of confirming the finding in additional cohorts as well as running prospective studies looking at the impact of risk factor modification.

Dr. Shah and her associates used data collected at four U.S. centers from patients enrolled in the SEARCH for Diabetes in Youth study who underwent a tissue Doppler examination during 2016-2019, and used three measures derived from the scans to identify diastolic dysfunction:

• The E/A ratio, which compares the early flow wave across the mitral valve (E) with the atrial flow wave (A) that occurs after atrial contraction. Lower values reflect worse pathology.
• The E/e’ ratio, which compares the early flow wave across the mitral valve (E) with the rate of cardiac wall relaxation in early diastole (e’). Higher values reflect worse pathology.
• The e’/a’ ratio, which compares the rate of cardiac wall relaxation in early diastole (e’) with the rate of cardiac wall relaxation in late diastole (a’). Lower values reflect worse pathology.

The most common abnormality involved the e’/a’ measure, which occurred in roughly 38% of the patients with type 2 diabetes and in about 23% of those with type 1 diabetes. Next most common was an abnormally high E/e’ ratio, and fewer than 10% of patients had an abnormally low E/A ratio. Both the E/A and E/e’ values were significantly worse among patients with type 2 diabetes compared with type 1 patients, while no statistically significant difference separated the two subgroups for prevalence of an e’/a’ abnormality after adjustment for body mass index, blood pressure, and HbA_1c values.

Average body mass index among the 221 studied patients with type 2 diabetes was 38 kg/m², 74% were girls or women, and 57% were non-Hispanic black and 24% non-Hispanic white. Mean blood pressure among the patients with type 2 diabetes was 123/80 mm Hg, while it was 110/72 mm Hg among the 258 patients with type 1 diabetes.

Using tissue Doppler echocardiography findings from 258 adolescents and young adults with type 1 diabetes, and 221 with type 2 diabetes, the study found at least one imaging marker of ventricular stiffness – diastolic dysfunction – in 58% of the patients with type 2 diabetes and in 47% of those with type 1 diabetes. The type 1 patients averaged 21 years of age with a median 12 years of diagnosed disease, while the type 2 patients had an average age of 25 years and a median 11 years disease duration.

The analysis also identified several measures that significantly linked with the presence of diastolic dysfunction: older age, female sex, nonwhite race, type 2 diabetes, higher heart rate, higher body mass index, higher systolic blood pressure, and higher hemoglobin A_1c.

“Our data suggest targeting modifiable risk factors” in these patients in an effort to slow the process causing the diastolic dysfunction, Amy S. Shah, MD, said at the virtual annual scientific sessions of the American Diabetes Association. She particularly cited interventions aimed at reducing body mass index, lowering blood pressure, and improving glycemic control, as well as preventing type 2 diabetes in the first place.

Prevention of type 2 diabetes, as well as prevention of diastolic dysfunction development and progression, are key steps because of the substantial clinical consequences of diastolic dysfunction, triggered by stiffening of the left ventricle. Diastolic dysfunction leads to increased left ventricular diastolic pressure, left atrial dysfunction, and ultimately heart failure with preserved ejection fraction, a common diabetes complication that currently has no treatment with proven efficacy, said Dr. Shah, a pediatric endocrinologist and director of the Adolescent Type 2 Diabetes Program at Cincinnati Children’s Hospital Medical Center.

“It’s very concerning that diastolic dysfunction is so prevalent in this age group,” commented Robert A. Gabbay, MD, Chief Science & Medical Officer of the American Diabetes Association. “An important question is whether you can see an improvement by reversing risk factors.” He noted the importance of confirming the finding in additional cohorts as well as running prospective studies looking at the impact of risk factor modification.

Dr. Shah and her associates used data collected at four U.S. centers from patients enrolled in the SEARCH for Diabetes in Youth study who underwent a tissue Doppler examination during 2016-2019, and used three measures derived from the scans to identify diastolic dysfunction:

• The E/A ratio, which compares the early flow wave across the mitral valve (E) with the atrial flow wave (A) that occurs after atrial contraction. Lower values reflect worse pathology.
• The E/e’ ratio, which compares the early flow wave across the mitral valve (E) with the rate of cardiac wall relaxation in early diastole (e’). Higher values reflect worse pathology.
• The e’/a’ ratio, which compares the rate of cardiac wall relaxation in early diastole (e’) with the rate of cardiac wall relaxation in late diastole (a’). Lower values reflect worse pathology.

The most common abnormality involved the e’/a’ measure, which occurred in roughly 38% of the patients with type 2 diabetes and in about 23% of those with type 1 diabetes.

Racial and socioeconomic disparities may be impeding access to newer diabetes medications among U.S. patients who may need them the most, according to researchers at the virtual annual scientific sessions of the American Diabetes Association.

Initiation of DPP-4 inhibitors, GLP-1 receptor agonists, and SGLT2 inhibitors was less likely among racial/ethnic minorities and Medicare Advantage beneficiaries in the retrospective analyses, leading the investigators to call for a better understanding of nonclinical factors that may be influencing treatment decisions.

Odds of new diabetes medication use were 55%-69% lower in patients in Medicare Advantage (MA) as compared to patients in commercial health plans, according to results of a separate study presented by Rozalina McCoy, MD, endocrinologist and researcher with Mayo Clinic, Rochester, Minn.

“The rates of use are increasing over time, but not enough in MA beneficiaries,” she said in her virtual presentation. “I think it really calls for more to be done to ensure access to and use of evidence based medications, by all people with type 2 diabetes.”

The likelihood of initiating a new diabetes drug was 29% lower among African Americans and 49% lower among Native Americans in a study of enrollees in the Look AHEAD (Action for Health in Diabetes) randomized trial, according to researcher Ahmed Elhussein, BMBCh, MPH, of the Johns Hopkins Bloomberg School of Public Health.

“This is particularly concerning, because they might have a greater need for these new diabetes medications, but reduced access,” Dr. Elhussein said in his presentation.

Disparities by race in diabetes drug use

The prevalence of type 2 diabetes in the United States is higher among racial and ethnic minorities, at about 12%-15%, versus about 7% in whites, according to Dr. Elhussein,

While the newer classes of diabetes medications have a lower risk of hyperglycemia and have cardiovascular and renal benefits, they also come at a higher cost, he added.

“This has created some concerns about access in particular for underserved groups,” he said in his presentation.

In their retrospective analysis, based on 4,892 patients enrolled in the Look AHEAD (Action for Health in Diabetes) randomized trial, Dr. Elhussein and coinvestigators identified 44% who had initiated a newer diabetes medication over a median follow-up of about 8 years.

They found black race was associated with significantly lower initiation of newer medications compared to whites, with a hazard ratio of 0.81 (95% confidence interval 0.80-0.94; P = 0.019), after adjustment for socioeconomic status.

New diabetes medication use was also significantly lower among American Indian/Alaskan Natives, with an HR of 0.51 and a confidence interval that did not include the null value of 1, according to the investigator.

No significant differences in new diabetes drug use were seen in Hispanics or those classified as other race/ethnicity, he added.

“We’d advocate for more study to try to understand what are the drivers of this disparity,” he said. “This would let us develop interventions that might help to increase access in these patient groups that might need them the most.”

Insurance type and diabetes drugs

Second-line medications, including GLP-1 receptor agonists and SGLT2 inhibitors, have “preferred” efficacy and side effect profiles, but are more costly than older, generic options such as sulfonylureas, which may affect the likelihood of their use, said Dr. McCoy, the Mayo Clinic researcher and lead author of the study on diabetes medication use by insurance type.

They analyzed 1.7 million individuals in a de-identified dataset (OptumLabs Data Warehouse) who were either privately insured or beneficiaries of Medicare Advantage, the private health plan alternative to fee-for-service Medicare.

After adjusting for race/ethnicity, baseline medications, age, gender, and other factors, odds of new medication use were significantly lower in the Medicare Advantage group, according to Dr. McCoy.

Odds ratios ranged from 0.61 (95% CI, 0.60-0.63) for DPP-4 inhibitors, to 0.45 (95% CI, 0.44-0.46) for GLP-1 receptor agonists, and to 0.31 (95% CI, 0.30-0.31) for SGLT2 inhibitors, she reported.

“This may be driven by affordability, because patients with Medicare Advantage plans are not able to access prescription savings cards (as compared to Medicare beneficiaries) and they also are more likely to have fixed incomes and not be able to afford the high costs of these drugs,” she said.

Dr. Elhussein reported no disclosures related to the research, while co-authors provided disclosures related to Abbott, Bigfoot Biomedical, Boehringer Ingelheim, Eli Lilly, MannKind, Medscape, Novo Nordisk, Sanofi US, and others. Dr McCoy likewise had no disclosures, while co-authors indicated disclosures related to Janssen Pharmaceuticals, the Centers for Medicare and Medicaid Services, and the U.S. Food and Drug Administration.

Patients with type 2 diabetes treated with the SGLT2 inhibitor empagliflozin during the landmark EMPA-REG OUTCOME trial had a solidly reduced need to either start insulin treatment or intensify existing insulin treatment, compared with those given placebo, in a post-hoc analysis of the study’s findings.

Mitchel L. Zoler/Frontline Medical News

“Empagliflozin markedly and durably delayed the need for insulin initiation, and reduced the need for large dose increases in patients already using insulin,” Muthiah Vaduganathan, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The patients in the empagliflozin (Jardiance) arm of EMPA-REG OUTCOME had a 9% rate of initiating insulin treatment after 4 years in the study, compared with a 20% rate among patients who received placebo, a statistically significant 60% relative risk reduction. All patients in the trial continued on their background oral glucose-lowering medications.

Among the 48% of study patients who entered the study already using insulin as part of their usual regimen, 18% of those receiving empagliflozin required a significant increase in their insulin dosage (an increase of at least 20% from baseline) after 4 years. But among the control patients, 35% needed this level of insulin-dosage intensification, again a statistically significant difference that computed to a 58% relative reduction in the need for boosting the insulin dosage.

For both of these endpoints, the divergence between the empagliflozin and control arms became apparent within the first 6 months on treatment, and the between-group differences steadily increased during further follow-up. The analyses pooled the patients who received empagliflozin in the trial, which studied two different dosages of the drug.

Results add to the ‘risk and benefit conversation’

“This is one of the first studies to look at this question in a more granular fashion” in patients with type 2 diabetes receiving a drug from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class, said Dr. Vaduganathan, a cardiologist at Brigham and Women’s Hospital in Boston. It provides “compelling” information to include when discussing oral diabetes-drug options with patients, he said in an interview.

Patients newly diagnosed with type 2 diabetes “often think about insulin” and their potential need to eventually start taking it, with the requirements it brings for training, monitoring, and drug delivery, along with the costs for insulin and glucose monitoring. “Patients are very attuned to potentially needing insulin and often ask about it. A reduced need for insulin will be an important part of the risk and benefit conversation” with patients about potential use of an SGLT2 inhibitor, he said.

Dr. Vaduganathan hypothesized that three factors could contribute to the impact of empagliflozin on insulin initiation and dosage level: a direct glycemic-control effect of the drug, the drug’s positive impact on overall well-being and function that could enhance patient movement, and the documented ability of treatment with empagliflozin and other drugs in its class to cut the rate of heart failure hospitalizations. This last feature is potentially relevant because insulin treatment often starts in patients with type 2 diabetes during a hospitalization, he noted.
 

Handelsman: Analysis shows no ‘spectacular effect’

The association of empagliflozin treatment with a reduced need for insulin seen in these data is consistent with expectations for patients with type 2 diabetes who receive an additional oral drug, commented Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of The Metabolic Institute of American in Tarzana, Calif. “In large part it has to do with patients on placebo having to get more insulin” because their additional oral-drug options were limited. Dr. Handelsman pointed out that during the period when the EMPA-REG OUTCOME trial ran, from 2010-2015, fewer oral drugs were available than today, and clinicians in the study were encouraged to treat patients to their goal glycemia level according to local guidelines. In addition to a modest but useful glycemic control effect from SGLT2 inhibitors that, on average, cut hemoglobin A_1c levels by about 0.5%, they may also give a small boost to insulin sensitivity that can also defer the need to add or increase insulin. The level of insulin-treatment deference reported in the new analysis was “not a spectacular effect” he said in an interview.

The EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) study followed 7,020 patients at 590 sites in 42 countries for a median of 3.1 years. The study’s primary endpoint was a composite of death from cardiovascular causes, nonfatal myocardial infarction (excluding silent MI), or nonfatal stroke, and the results showed a statistically significant 14% relative risk reduction with empagliflozin treatment (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ). The results also showed that 12 weeks into the study, before patients could receive any additional drugs, HbA_1c levels averaged 0.54%-0.6% lower among the empagliflozin-treated patients than those in the placebo arm, with smaller between-group differences maintained through the balance of the study. At entry, more than half the enrolled patients were routinely treated with metformin, and close to half were receiving a sulfonyurea agent.

The EMPA-REG OUTCOME results were also notable as showing for the first time that treatment with an SGLT2 inhibitor drug produced a substantial decrease in heart failure hospitalizations, incident heart failure, and progression of renal dysfunction, effects subsequently confirmed and also found for other agents in this drug class.

EMPA-REG OUTCOME was funded in part by Boehringer Ingelheim and Eli Lilly, the companies that market empagliflozin (Jardiance). Dr. Vaduganathan has been an advisor to Boehringer Ingelheim and to Amgen, AstraZeneca, Baxter, Bayer, Cytokinetics, and Relypsa. Dr. Handelsman has been a consultant to several drug companies including Boehringer Ingelheim and Eli Lilly.

Dr. Handelsman pointed out that during the period when the EMPA-REG OUTCOME trial ran, from 2010-2015, fewer oral drugs were available than today, and clinicians in the study were encouraged to treat patients to their goal glycemia level according to local guidelines. In addition to a modest but useful glycemic control effect from SGLT2 inhibitors that, on average, cut hemoglobin A_1c levels by about 0.5%, they may also give a small boost to insulin sensitivity that can also defer the need to add or increase insulin. The level of insulin-treatment deference reported in the new analysis was “not a spectacular effect” he said in an interview.

The EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) study followed 7,020 patients at 590 sites in 42 countries for a median of 3.1 years. The study’s primary endpoint was a composite of death from cardiovascular causes, nonfatal myocardial infarction (excluding silent MI), or nonfatal stroke, and the results showed a statistically significant 14% relative risk reduction with empagliflozin treatment (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ). The results also showed that 12 weeks into the study, before patients could receive any additional drugs, HbA_1c levels averaged 0.54%-0.6% lower among the empagliflozin-treated patients than those in the placebo arm, with smaller between-group differences maintained through the balance of the study. At entry, more than half the enrolled patients were routinely treated with metformin, and close to half were receiving a sulfonyurea agent.

The EMPA-REG OUTCOME results were also notable as showing for the first time that treatment with an SGLT2 inhibitor drug produced a substantial decrease in heart failure hospitalizations, incident heart failure, and progression of renal dysfunction, effects subsequently confirmed and also found for other agents in this drug class.

EMPA-REG OUTCOME was funded in part by Boehringer Ingelheim and Eli Lilly, the companies that market empagliflozin (Jardiance).

Patients with type 2 diabetes treated with the SGLT2 inhibitor empagliflozin during the landmark EMPA-REG OUTCOME trial had a solidly reduced need to either start insulin treatment or intensify existing insulin treatment, compared with those given placebo, in a post-hoc analysis of the study’s findings.

“Empagliflozin markedly and durably delayed the need for insulin initiation, and reduced the need for large dose increases in patients already using insulin,” Muthiah Vaduganathan, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The patients in the empagliflozin (Jardiance) arm of EMPA-REG OUTCOME had a 9% rate of initiating insulin treatment after 4 years in the study, compared with a 20% rate among patients who received placebo, a statistically significant 60% relative risk reduction. All patients in the trial continued on their background oral glucose-lowering medications.

Among the 48% of study patients who entered the study already using insulin as part of their usual regimen, 18% of those receiving empagliflozin required a significant increase in their insulin dosage (an increase of at least 20% from baseline) after 4 years. But among the control patients, 35% needed this level of insulin-dosage intensification, again a statistically significant difference that computed to a 58% relative reduction in the need for boosting the insulin dosage.

For both of these endpoints, the divergence between the empagliflozin and control arms became apparent within the first 6 months on treatment, and the between-group differences steadily increased during further follow-up. The analyses pooled the patients who received empagliflozin in the trial, which studied two different dosages of the drug.

Results add to the ‘risk and benefit conversation’

“This is one of the first studies to look at this question in a more granular fashion” in patients with type 2 diabetes receiving a drug from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class, said Dr. Vaduganathan, a cardiologist at Brigham and Women’s Hospital in Boston. It provides “compelling” information to include when discussing oral diabetes-drug options with patients, he said in an interview.

Patients newly diagnosed with type 2 diabetes “often think about insulin” and their potential need to eventually start taking it, with the requirements it brings for training, monitoring, and drug delivery, along with the costs for insulin and glucose monitoring. “Patients are very attuned to potentially needing insulin and often ask about it. A reduced need for insulin will be an important part of the risk and benefit conversation” with patients about potential use of an SGLT2 inhibitor, he said.

Dr. Vaduganathan hypothesized that three factors could contribute to the impact of empagliflozin on insulin initiation and dosage level: a direct glycemic-control effect of the drug, the drug’s positive impact on overall well-being and function that could enhance patient movement, and the documented ability of treatment with empagliflozin and other drugs in its class to cut the rate of heart failure hospitalizations. This last feature is potentially relevant because insulin treatment often starts in patients with type 2 diabetes during a hospitalization, he noted.

In its first media briefing on coronavirus in more than 3 months, the Centers for Disease Control and Prevention (CDC) warned that the COVID-19 pandemic is not over, and large gatherings pose a high risk for COVID-19 transmission.

Robert Redfield, MD, Director, CDC, and Jay C. Butler, MD, Deputy Director of Infectious Diseases and COVID-19 Response Incident Manager, CDC, discussed two new sets of CDC guidance on deciding to go out and attending group gatherings.

“We recognize that we’re all getting tired of staying at home; people long for the life that they had back in December, and as we head into the summer months, we know that Americans will be looking forward to reconnecting with family and friends and being able to attend events, and we want that to occur as safely as possible,” Butler said.

“Our recommendations evolved based on new information that becomes available, but it continues to be extremely important that we embrace the recommendations of social distancing, handwashing, and wearing a face covering when we’re in public as some of the key defenses that we have against this virus,” Redfield explained.

“The pandemic is not over and it’s important to recognize that. While COVID-19 is still making headlines everywhere, we know the pandemic hasn’t affected everyone everywhere in the same way,” Butler said.

He noted that it is important to prepare for next fall and winter, when we can expect influenza season to complicate matters. “If anything, we must be overly-prepared for what we might face later this year,” he continued, adding that it is important to get vaccinated against influenza. “[F]lu and COVID-19 could be circulating together as we move into the fall and winter months,” he concluded.

Americans Mostly Following Guidelines

The agency also presented data from an article published online June 12 in Morbidity and Mortality Weekly Report that “underscores the fact that American people have taken mitigation efforts seriously…and it demonstrates our collective spirit in responding to the pandemic,” Butler said.

In it, the researchers describe representative panel surveys conducted among 4042 adults aged 18 years or older in New York City and Los Angeles — the two most populous cities in the United States — and “broadly across the United States” during May 5 to May 12, 2020.

Most respondents supported stay-at-home orders and nonessential business closures (United States, 79.5%; New York City, 86.7%; Los Angeles, 81.5%) and always or often wore cloth face coverings in public (United States, 74.1%; New York City, 89.6%; Los Angeles, 89.8%). Respondents also agreed that nonessential workers should remain at home (United States, 67.3%; New York City, 76.6%; Los Angeles, 69.1%), report Mark É. Czeisler, from Monash University and Austin Health, both in Melbourne, Australia, and colleagues.

There was wide support with public health guidelines: more than 87% of individuals in each area agreed that individuals should keep six feet of distance between themselves and others, and more than 82% in each area said that people should limit gatherings to fewer than 10 individuals.

At the time the survey was conducted, most were against indoor dining at restaurants (United States, 66.6%; New York City, 81.5%; Los Angeles, 71.8%).

Adherence “Widespread,” Survey Finds

Most respondents said they were adhering to COVID-19 mitigation guidance, including self-isolating (United States, 77.3%; New York City, 84.6%; Los Angeles, 83.0%) and “always or often” kept at least six feet between themselves and others (New York City, 85.7%; Los Angeles, 82.6%).

More than 85% of respondents in each of the three cohorts said they always or often avoided groups of 10 or more individuals.

About 90% of respondents said they had been in a public area during the last week, with 74.1% of those saying they always or often covered their face in public; respondents in New York City (89.6%) and Los Angeles (89.8%) had higher percentages of this behavior compared with respondents from the United States overall.

Most respondents felt that restrictions in their state were balanced or too lax (United States, 84.3%; New York City, 89.7%; Los Angeles, 79.7%) and said they would feel unsafe if restrictions were eased nationwide at that time (United States, 74.3%; New York City, 81.5%; Los Angeles, 73.4%). However, some individuals who said they would feel unsafe still wanted community mitigation strategies eased and were willing to accept risks resulting from lifting restrictions (United States, 17.1%; New York City, 12.6%; Los Angeles, 12.7%).

“Reported prevalence of self-isolation and feeling safe if community mitigation strategies were lifted differed significantly by age, employment status, and essential worker status among adults in the U.S. survey cohort,” the authors write.

Reports of self-isolation were highest among persons aged 18 to 24 years (92.3%) and lowest among those aged 45 to 54 years (71.5%). Yet, young adults aged 18 to 24 years (43.1%) were more than twice as likely to say they would feel safe if community mitigation strategies were eased, compared with adults aged 65 years or older (19.2%).

Almost half (47.2%) of employed respondents in the US cohort were essential workers; essential workers were “significantly less likely” to report self-isolating when compared with nonessential workers (63.1% vs 80.6%). Some 37.7% of essential workers said they would feel safe if community mitigation strategies were eased, compared with 23.7% of nonessential workers.

“Respondents who were male, employed, or essential workers were significantly more likely to report having been in public areas in the past week. Among respondents who had been in public areas during the preceding week, significantly higher percentages of women, adults aged ≥ 65 years, retired persons, and those living in urban areas reported wearing cloth face coverings,” the authors explain.

The findings are subject to several limitations, including self-reporting and the fact that some respondents may have known someone who tested positive for COVID-19 or died from it, the authors note. Respondents were not representative of the US population and the findings may not be generalizable.

Medtronic’s next-generation automated insulin delivery system offers significant improvements over the currently available 670G hybrid closed-loop, particularly in young people with type 1 diabetes, new data suggest.

Automated insulin delivery systems are comprised of an insulin pump, continuous glucose monitor (CGM), and an automated insulin dosing algorithm.

Data from three trials of such systems using Medtronic’s advanced hybrid closed-loop (AHCL) algorithm (trade name SmartGuard) were presented June 12 during the virtual American Diabetes Association (ADA) 80th Scientific Sessions. The AHCL is the algorithm used in Medtronic’s new MiniMed 780G system, which received a CE Mark on June 11 for the treatment of type 1 diabetes in people aged 7 to 80 years.

One trial, presented by Bruce W. Bode, MD, of Atlanta Diabetes Associates, Georgia, was the US pivotal safety study that will be submitted to the US Food and Drug Administration for approval of the Medtronic 780G.

Another trial, presented by Richard M. Bergenstal, MD, executive director of the International Diabetes Center at Park Nicollet, Minneapolis, Minnesota, was a separate comparison of the AHCL with the 670G. (The AHCL-based system used in the three trials was identical to the 780G except it didn’t include Bluetooth, which will be a feature of the final product.)

A third trial, presented by Martin de Bock, PhD, of the University of Otago, New Zealand, included the CE Mark dataset for the 780G.

In contrast to the 670G, the 780G adds automated correction boluses for high blood glucose levels (rather than simply adjusting the basal infusion) and allows for adjustment of target glucose levels down to 100 mg/dL rather than a minimum of 120 mg/dL.

Taken together, the data from the three trials showed that the AHCL-based system improved glycemic time-in-range with no increased risk for hypoglycemia, including in children and teenagers, with high patient-reported satisfaction. And specifically compared to the 670G, the AHCL-based system reverts to open-loop far less often because it only exits closed-loop mode when the sensor stops working or during sensor changes, but not during hyperglycemia even above 300 mg/dL.

Asked to comment, session moderator Timothy S. Bailey, MD, president and CEO of the AMCR Institute, Escondido, California, told Medscape Medical News: “Automated insulin delivery systems are getting better and better.”

“None of these devices is perfect, but they are a substantial improvement over what we’ve had ... They all take people from where they are now to better time-in-range, less time with hypoglycemia, and most important, they might make the quality of their lives better. That’s really underappreciated.”

One factor that has allowed for the improvements, Bailey said, is the recognition by regulatory bodies that the hybrid closed-loop devices are generally safer than current open-loop type 1 diabetes management so that fewer “safety” device features that interfere with tight glycemic control are necessary.

With first-generation closed-loop systems, “If a wide variety of conditions occur, users get kicked off [hybrid closed-loop mode]. Originally it was perceived by the regulatory agencies as a safety feature because they perceived the standard of care as safe. The new system was allowed to have fewer rules.”
 

Pivotal trial: Time-in-range improved, 96% say system easy to use

The goal of the AHCL system is to maximize the time-in-range of blood glucose between 70-180 mg/dL. Automated basal delivery of insulin is programmed to a set-point of 100 or 120 mg/dL, with dosing every 5 minutes.

The US pivotal trial was a single-arm, 16-center, in-home trial of 157 people with type 1 diabetes, including 39 adolescents aged 14-21 years and 118 adults aged 22-75 years. All had type 1 diabetes for at least 2 years, A_1c levels below 10%, and had been using insulin pumps for at least 6 months, with or without CGMs.

After a 14-day run-in, they wore the systems with a 100 or 120 mg/dL set-point for 45 days, then switched to the other setpoint for another 45 days. Average A1c dropped from 7.5% to 7.0%, with the proportions having an A1c ≤ 7.0% increasing from 34% to 61%.

Overall time-in-range was 75% compared to 69% at baseline, with time below range (< 70 mg/dL) of 1.8%. Overnight time-in-range was 82%, with 1.5% below range. Time-in-range increased from 62% to 73% in the adolescents and from 71% to 75% in the adults.

There were no incidences of severe hypoglycemia or diabetic ketoacidosis, and no device-related serious adverse events.

Participants reported being in hybrid closed-loop, or auto-mode, 95% of the time, compared with 33% for those who had been previously using the 670G.

The number of AHCL exits was 1.3 per week, significantly less than with the 670G. Of those, 29% were user-initiated while the rest were implemented by the device, most often when the sensor wasn’t working.

In a study questionnaire, 96% reported that the system was easy to use.
 

AHCL vs 670G: Major improvements seen

Bergenstal presented data from the Fuzzy Logic Automated Insulin Regulation (FLAIR) study, funded by the National Institute of Diabetes and Digestive and Kidney Disease, comparing Medtronic’s AHCL-based system with the currently marketed 670G hybrid closed-loop, in 113 individuals with type 1 diabetes aged 14-29 years.

“This age group has traditionally been the most difficult group in which to optimize glucose management,” Bergenstal said.

FLAIR is believed to be the first-ever study comparing an investigational automated insulin delivery system with a commercially approved system, he noted. All participants used each automated insulin delivery system for 3 months in the randomized crossover trial.

The primary outcome, time spent above 180 mg/dL during the day combined with time below 54 mg/dL over 24 hours at baseline with the 670G and AHCL went from 42% to 37% to 34%, respectively, for the former and from 0.46% to 0.50% to 0.45%, respectively, for the latter.

The percentage time-in-range over 24 hours went from 57% at baseline to 67% with the AHCL versus 63% with the 670G. A1c levels dropped from 7.9% at baseline to 7.6% with the 670G and 7.4% with AHCL.

“Remember, these are the adolescents who are the toughest of the tough, yet there was a 10% increase in time-in-range ... this is very clinically significant,” Bergenstal said.

Even among 14 patients who had been using multiple daily injections without CGM prior to the study, a group often excluded from closed-loop studies, time-in-range improved from 45% at baseline to 63% with the 670G to 65% with AHCL.

“I’m making a plea not to exclude people just because they haven’t previously used technology,” Bergenstal said.

One patient who had dosed with extra insulin manually had a severe hypoglycemia event with AHCL. No patient had diabetic ketoacidosis.

The proportion of insulin given as auto-correction boluses was 36%, which is important as it means that the system was compensating for missed meal doses, a common phenomenon among teenagers, Bergenstal noted.

“There is still room for further improvement in glycemic control in this population of patients with type 1 diabetes, but AHCL represents a significant step forward,” he concluded.
 

New Zealand study: More data in youth show AHCL benefits

Unlike the US study populations of just teens aged 14 and older, and adults, the study data used for approval in the EU — from New Zealand — included a total of 60 patients with 20 children aged 7-15 years. It, too, was a 10-week randomized crossover clinical trial comparing the AHCL to a sensor-augmented pump system with an algorithm only for predictive low-glucose management (PLGM) and no adjustments for high blood glucose.

Time-in-range was 59% at baseline and 58% with PLGM, compared to 70.4% with AHCL, and most of the time-in-range improvement occurred at night. Time below 70 mg/dL dropped from 3.1% to 2.5% to 2.1%, respectively.

Similar to the US studies, participants spent 96% of the time in closed-loop mode with only 1.2 exits per week. On a questionnaire, 95% of patients agreed that the system was easy to use and 85% that the system improved their quality of life.

De Bock showed a slide with some quotes, including one from a parent saying, “We didn’t have to be fearful at night or have that thought when we opened her bedroom door in the morning that she might not be conscious,” and from a patient, “I forgot I had diabetes today.”

Bailey commented: “Of course these devices are not free. So, the challenge is how do we make them available, less expensive, and easy to use? We have our work cut out for us, but this is heartening data. Everything has gotten better but we’re not out of a job yet.”

Medtronic’s next-generation automated insulin delivery system offers significant improvements over the currently available 670G hybrid closed-loop, particularly in young people with type 1 diabetes, new data suggest.

Automated insulin delivery systems are comprised of an insulin pump, continuous glucose monitor (CGM), and an automated insulin dosing algorithm.

Data from three trials of such systems using Medtronic’s advanced hybrid closed-loop (AHCL) algorithm (trade name SmartGuard) were presented June 12 during the virtual American Diabetes Association (ADA) 80th Scientific Sessions. The AHCL is the algorithm used in Medtronic’s new MiniMed 780G system, which received a CE Mark on June 11 for the treatment of type 1 diabetes in people aged 7 to 80 years.

One trial, presented by Bruce W. Bode, MD, of Atlanta Diabetes Associates, Georgia, was the US pivotal safety study that will be submitted to the US Food and Drug Administration for approval of the Medtronic 780G.

Another trial, presented by Richard M. Bergenstal, MD, executive director of the International Diabetes Center at Park Nicollet, Minneapolis, Minnesota, was a separate comparison of the AHCL with the 670G. (The AHCL-based system used in the three trials was identical to the 780G except it didn’t include Bluetooth, which will be a feature of the final product.)

A third trial, presented by Martin de Bock, PhD, of the University of Otago, New Zealand, included the CE Mark dataset for the 780G.

In contrast to the 670G, the 780G adds automated correction boluses for high blood glucose levels (rather than simply adjusting the basal infusion) and allows for adjustment of target glucose levels down to 100 mg/dL rather than a minimum of 120 mg/dL.

Taken together, the data from the three trials showed that the AHCL-based system improved glycemic time-in-range with no increased risk for hypoglycemia, including in children and teenagers, with high patient-reported satisfaction. And specifically compared to the 670G, the AHCL-based system reverts to open-loop far less often because it only exits closed-loop mode when the sensor stops working or during sensor changes, but not during hyperglycemia even above 300 mg/dL.

Asked to comment, session moderator Timothy S. Bailey, MD, president and CEO of the AMCR Institute, Escondido, California, told Medscape Medical News: “Automated insulin delivery systems are getting better and better.”

“None of these devices is perfect, but they are a substantial improvement over what we’ve had ... They all take people from where they are now to better time-in-range, less time with hypoglycemia, and most important, they might make the quality of their lives better. That’s really underappreciated.”

One factor that has allowed for the improvements, Bailey said, is the recognition by regulatory bodies that the hybrid closed-loop devices are generally safer than current open-loop type 1 diabetes management so that fewer “safety” device features that interfere with tight glycemic control are necessary.

With first-generation closed-loop systems, “If a wide variety of conditions occur, users get kicked off [hybrid closed-loop mode]. Originally it was perceived by the regulatory agencies as a safety feature because they perceived the standard of care as safe. The new system was allowed to have fewer rules.”
 

Pivotal trial: Time-in-range improved, 96% say system easy to use

The goal of the AHCL system is to maximize the time-in-range of blood glucose between 70-180 mg/dL. Automated basal delivery of insulin is programmed to a set-point of 100 or 120 mg/dL, with dosing every 5 minutes.

The US pivotal trial was a single-arm, 16-center, in-home trial of 157 people with type 1 diabetes, including 39 adolescents aged 14-21 years and 118 adults aged 22-75 years. All had type 1 diabetes for at least 2 years, A_1c levels below 10%, and had been using insulin pumps for at least 6 months, with or without CGMs.

After a 14-day run-in, they wore the systems with a 100 or 120 mg/dL set-point for 45 days, then switched to the other setpoint for another 45 days. Average A1c dropped from 7.5% to 7.0%, with the proportions having an A1c ≤ 7.0% increasing from 34% to 61%.

Overall time-in-range was 75% compared to 69% at baseline, with time below range (< 70 mg/dL) of 1.8%. Overnight time-in-range was 82%, with 1.5% below range. Time-in-range increased from 62% to 73% in the adolescents and from 71% to 75% in the adults.

There were no incidences of severe hypoglycemia or diabetic ketoacidosis, and no device-related serious adverse events.

Participants reported being in hybrid closed-loop, or auto-mode, 95% of the time, compared with 33% for those who had been previously using the 670G.

The number of AHCL exits was 1.3 per week, significantly less than with the 670G. Of those, 29% were user-initiated while the rest were implemented by the device, most often when the sensor wasn’t working.

In a study questionnaire, 96% reported that the system was easy to use.
 

AHCL vs 670G: Major improvements seen

Bergenstal presented data from the Fuzzy Logic Automated Insulin Regulation (FLAIR) study, funded by the National Institute of Diabetes and Digestive and Kidney Disease, comparing Medtronic’s AHCL-based system with the currently marketed 670G hybrid closed-loop, in 113 individuals with type 1 diabetes aged 14-29 years.

“This age group has traditionally been the most difficult group in which to optimize glucose management,” Bergenstal said.

FLAIR is believed to be the first-ever study comparing an investigational automated insulin delivery system with a commercially approved system, he noted. All participants used each automated insulin delivery system for 3 months in the randomized crossover trial.

The primary outcome, time spent above 180 mg/dL during the day combined with time below 54 mg/dL over 24 hours at baseline with the 670G and AHCL went from 42% to 37% to 34%, respectively, for the former and from 0.46% to 0.50% to 0.45%, respectively, for the latter.

In a pilot study of five patients with ventricular tachycardia (VT) storm that was refractory to antiarrhythmic drug therapy, treatment with noninvasive transcutaneous magnetic stimulation (TCMS) was associated with a lower arrhythmia burden.

The five patients were men aged 40 to 68 years with VT storm, defined as at least three episodes of sustained VT in the preceding 24 hours. The patients experienced a drop in both sustained and nonsustained VT with TCMS.

The study “aimed at developing a novel system for noninvasively and nondestructively interrupting the sympathetic tone,” corresponding author Timothy M. Markman, MD, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, told theheart.org | Medscape Cardiology. “We demonstrated that the technique was safe and that there was a strong signal of efficacy,” he added.

“We know that interrupting the sympathetic tone in these patients is beneficial,” said Markman, “but our strategies for doing so are mostly invasive and associated with a significant risk profile.”

The research letter was published online May 5 in the Journal of the American Medical Association. It was also presented during the virtual Heart Rhythm Society 2020 conference.

Growing body of evidence

Numerous studies have linked autonomic neuromodulation, including local blockade of the left stellate ganglion, with a reduction of cardiac sympathetic input in patients with VT storm, the authors write.

“This adds to a growing body of literature that autonomic neuromodulation is a valuable tool in the management of arrhythmias,” said Markman.

The use of magnetic stimulation to treat arrhythmias by targeting cardiac sympathetic innervation has been demonstrated in animal studies. The authors note that, to their knowledge, this is the first study involving humans.

Evidence suggests that TCMS may serve as a bridge for patients with difficult-to- treat VT to reduce VT and eliminate antiarrhythmic drug therapies and the associated risks, the authors say.
 

A lower VT burden

Five participants were included in the study. The patients were followed from March 2019 to June 2019. All had experienced at least three episodes of sustained VT (>30 sec) in the 24 hours preceding treatment. Patients with implantable cardiac devices were excluded.

The investigators used a figure 8 TCMS coil that was attached to a magnetic stimulation system positioned lateral to the C7 spinous process in approximation of the left stellate ganglion. TCMS was delivered at 80% of the left trapezius motor threshold at a frequency of 0.9 Hz for 60 minutes, the authors write. For one patient (patient no. 4), TCMS was shut off after 17 minutes, owing to the coil’s overheating. That resulted in the patient’s not being able to complete the protocol, they note.

Patients were monitored during and immediately after treatment for adverse events, including hemodynamic compromise, local discomfort, and skin irritation.

Results showed that compared to the 24-hour baseline period, sustained VT was reduced from 99 to five episodes, and nonsustained VT was reduced from 150 to 58 episodes in the 48 hours following TCMS.

A potential addition to treatment

Gordon F. Tomaselli, MD, past president of the American Heart Association and current dean of the Albert Einstein College of Medicine, New York City, who was not involved in the research, told theheart.org | Medscape Cardiology that “the results are kind of interesting; it actually changes the function in the ganglion in the neck that actually innervates the heart, excites the heart, if you will.

For one patient (patient no. 4), TCMS was shut off after 17 minutes, owing to the coil’s overheating. That resulted in the patient’s not being able to complete the protocol, they note.

Patients were monitored during and immediately after treatment for adverse events, including hemodynamic compromise, local discomfort, and skin irritation.

Results showed that compared to the 24-hour baseline period, sustained VT was reduced from 99 to five episodes, and nonsustained VT was reduced from 150 to 58 episodes in the 48 hours following TCMS.

A potential addition to treatment

Gordon F. Tomaselli, MD, past president of the American Heart Association and current dean of the Albert Einstein College of Medicine, New York City, who was not involved in the research, told theheart.org | Medscape Cardiology that “the results are kind of interesting; it actually changes the function in the ganglion in the neck that actually innervates the heart, excites the heart, if you will.

Racism, COVID-19 lead to sky-high stress levels

Primary care clinicians, already experiencing all-time high stress levels related to COVID-19, are now struggling to cope with the fallout from racism and the death of George Floyd, according to a survey conducted June 5-8.

When asked how the situation has affected their practices, 12% of the survey’s 586 respondents “drew clear connections between the current racial unrest and the health of their patients,” the Larry A. Green Center said in a recent statement. One-third of the clinicians also said that recent racism-related events have had a negative effect on their own well-being.

In a related survey of 1,111 patients conducted June 8 about 65% of patients said that racism affected emotional, psychological, and behavioral health.

“The fact that so many patients and clinicians agree that racism is a driver of health points to the incredible role primary care plays in creating safe spaces to process deep societal and personal issues,” said Christine Bechtel, cofounder of 3rd Conversation, a community of patients and providers.

Medical teams take to the streets

They stanched bleeding wounds and plucked disoriented teenagers from clouds of gas, entering dangerous corners where on-duty emergency health responders may fear to go. Many are medical professionals who see parallels between the front lines of COVID-19, where they confront stark racial imbalances among those stricken by the coronavirus, and what they see as racialized police brutality.

Iris Butler, a 21-year-old certified nursing assistant who works in a nursing home, decided to offer her skills after seeing a man injured by a rubber bullet on her first night at the Denver protests. She showed up as a medic every night thereafter. “I am working full time and basically being at the protest after getting straight off of work,” said Ms. Butler, who is black. That’s tiring, she added, but so is being a black woman in America. Read more.

At-home management of type 1 diabetes, COVID-19

Although hyperglycemia and diabetic ketoacidosis are common in people with type 1 diabetes who develop COVID-19, many are still able to manage the illness at home and overall mortality is relatively low.   

These new findings are still preliminary and were published online June 5 in Diabetes Care by Osagie A. Ebekozien, MD, vice president, quality improvement and population health at the T1D Exchange, and colleagues.

The published study includes data as of May 5 on 64 individuals from a total of 64 US sites. Since the paper was submitted, there are now 220 patients from 68 sites. There were two deaths in the preliminary report, Dr. Ebekozien said. There have been a few more deaths in the larger dataset, but the mortality rate remains relatively low.

Overall, 34.9% of patients were able to manage COVID-19 entirely at home. At the other extreme, 22.2% of patients overall were admitted to the intensive care unit. Including the small proportion of patients sent home after being seen in emergency or urgent care, overall roughly half were not admitted to the hospital. “Even in this preliminary study, half were managed at home via telemedicine with an endocrinologist and infectious disease specialist ... I think it continues to be a case-by-case clinical decision between the patient and their provider,” Dr. Ebekozien said. Read more.

‘Hospital at home’ for cancer patients

Visits to the emergency department (ED) and hospitalizations are often frequent occurrences for cancer patients, but what if the “hospital” could be brought into the home instead?

A new American cohort study provides evidence that this can be a workable option for cancer patients. The authors report improved patient outcomes, with 56% lower odds of unplanned hospitalizations, 45% lower odds of ED visits, and 50% lower cumulative charges, as compared with patients who received usual care.

“The oncology hospital-at-home model of care that extends acute-level care to the patient at home offers promise in addressing a long-term gap in cancer care service delivery,” said lead author Kathi Mooney, PhD, RN, distinguished professor of nursing at the University of Utah, Salt Lake City. “In light of the current global pandemic, we are compelled to consider new ways to provide cancer care, and the oncology hospital-at-home model is on point to address critical elements of an improved cancer care delivery system.”

Dr. Mooney presented the findings during the virtual scientific program of the American Society of Clinical Oncology 2020 annual meeting (abstract 7000). Read more.
