FDA clears app for FreeStyle Libre 2 glucose monitor
The Food and Drug Administration has cleared the FreeStyle Libre 2 iOS application for use with compatible iPhones.
The new app works with the FreeStyle Libre 2 with optional glucose alarms, which was approved in the United States in June 2020 for people with diabetes aged 4 years and older.
Until now, it was only a reader device with no app compatibility. The older FreeStyle Libre 14-day, available in the United States since July 2018, has both a reader and an app, but not optional alarms.
The new app, which will soon be available for download from the App Store, enables users to view glucose readings on their iPhones and allows for caregivers or other individuals to remotely monitor the patient’s glucose levels and receive real-time alarms via the LibreLinkUp app.
Worn for 14 days before replacement is needed, the FreeStyle Libre 2 is the longest-lasting integrated continuous glucose monitoring (iCGM) sensor currently on the market. The first iCGM, the Dexcom G6, is worn for 10 days.
The Libre 2 is available at pharmacies, typically at a lower cost than other CGM systems based on a list price comparison. The actual cost for patients varies depending on insurance coverage.
Abbott has secured partial or full reimbursement for the FreeStyle Libre system in 38 countries, including Canada, France, Germany, Japan, the United Kingdom, and the United States.
The FreeStyle Libre 3 is approved for use in the European Union.

‘Shocking’ early complications from teen-onset type 2 diabetes
Newly published data show alarmingly high rates and severity of early diabetes-specific complications in individuals who develop type 2 diabetes at a young age. This suggests intervention should be early and aggressive among these youngsters, said the researchers.
The results for the 500 young adult participants in the Treatment Options for Type 2 Diabetes in Adolescents and Youth 2 (TODAY 2) study were published online July 29 in the New England Journal of Medicine by the TODAY study group.
At follow-up – after originally participating in the TODAY trial when they were young teenagers – they had a mean age of 26.4 years.
At this time, more than two thirds had hypertension and half had dyslipidemia.
Overall, 60% had at least one diabetic microvascular complication (retinal disease, neuropathy, or diabetic kidney disease), and more than a quarter had two or more such complications.
“These data illustrate the serious personal and public health consequences of youth-onset type 2 diabetes in the transition to adulthood,” the researchers noted.
Don’t tread lightly just because they are young
“The fact that these youth are accumulating complications at a rapid rate and are broadly affected early in adulthood certainly suggests that aggressive therapy is needed, both for glycemic control and treatment of risk factors like hypertension and dyslipidemia,” study coauthor Philip S. Zeitler, MD, PhD, said in an interview.
“In the absence of studies specifically addressing this, we need to take a more aggressive approach than people might be inclined to, given that the age at diagnosis is young, around 14 years,” he added.
“Contrary to the inclination to be ‘gentle’ in treating them because they are kids, these data suggest that we can’t let these initial years go by without strong intervention, and we need to be prepared for polypharmacy.”
Unfortunately, as Dr. Zeitler and coauthors explained, youth-onset type 2 diabetes is characterized by a suboptimal response to currently approved diabetes medications.
New pediatric indications in the United States for drugs used to treat type 2 diabetes in adults, including the recent Food and Drug Administration approval of extended-release exenatide for children as young as 10 years of age, “helps, but only marginally,” said Dr. Zeitler, of the Clinical & Translational Research Center, Children’s Hospital Colorado, Aurora.
“In some cases, it will help get them covered by carriers, which is always good. But this is still a very limited set of medications. It doesn’t include more recently approved more potent glucagon-like peptide-1 (GLP-1) agonists, like semaglutide, and doesn’t include the sodium-glucose cotransporter 2 (SGLT2) inhibitors. Pediatricians are used to using medications off label and that is necessary here while we await further approvals,” he said.
And he noted that most individuals with youth-onset type 2 diabetes in the United States are covered by public insurance or are uninsured, depending on which state they live in. While the two major Medicaid programs in Colorado allow full access to adult formularies, that’s not the case everywhere. Moreover, patients often face further access barriers in states without expanded Medicaid.
Follow-up shows all metrics worsening over time
In TODAY 2, patients participated in an observational follow-up in their usual care settings in 2011-2020. At the start, they were receiving metformin with or without insulin for diabetes, but whether this continued and whether they were treated for other risk factors was down to individual circumstances.
Participants’ median A1c increased over time, and the percentage with A1c < 6% (< 48 mmol/mol) declined from 75% at the time of TODAY entry to just 19% at the 15-year end of follow-up.
The proportion with an A1c ≤ 10% (≤ 86 mmol/mol) rose from 0% at baseline to 34% at 15 years.
At that time, nearly 50% were taking both metformin and insulin, while more than a quarter were taking no medications.
The prevalence of hypertension increased from 19.2% at baseline to 67.5% at 15 years, while dyslipidemia rose from 20.8% to 51.6%.
Kidney disease prevalence increased from 8.0% at baseline to 54.8% at 15 years. Nerve disease rose from 1.0% to 32.4%. Retinal disease jumped from 13.7% with milder nonproliferative retinopathy in 2010-2011 to 51.0% with any eye disease in 2017-2018, including 8.8% with moderate to severe retinal changes and 3.5% with macular edema.
Overall, at the time of the last visit, 39.9% had no diabetes complications, 31.8% had one, 21.3% had two, and 7.1% had three complications.
Serious cardiovascular events in mid-20s
There were 17 adjudicated serious cardiovascular events, including four myocardial infarctions, six heart failure events, three diagnoses of coronary artery disease, and four strokes.
Six participants died, one each from myocardial infarction, kidney failure, and drug overdose, and three from sepsis.
Dr. Zeitler called the macrovascular events “shocking,” noting that although the numbers are small, for people in their mid-20s “they should be zero ... While we don’t yet know if the rates are the same or faster than in adults, even if they are the same, these kids are only in their late 20s, as opposed to adults experiencing these problems in their 50s, 60s, and 70s.
“The fact that these complications are occurring when these individuals should be in the prime of their life for both family and work has huge implications,” he stressed.
Findings have multiple causes
The reasons for the findings are both biologic and socioeconomic, Dr. Zeitler said.
“We know already that many kids with type 2 have rapid [deterioration of] beta-cell [function], which is probably very biologic. It stands to reason that an individual who can get diabetes as an adolescent probably has more fragile beta cells in some way,” he noted.
“But we also know that many other things contribute: stress, social determinants, access to quality care and medications, access to healthy foods and physical activity, availability of family supervision given the realities of families’ economic status and jobs, etc.”
It’s also known that youth with type 2 diabetes have much more severe insulin resistance than that of adults with the condition, and that “once the kids left ... the [TODAY] study, risk factor treatment in the community was less than ideal, and a lot of kids who met criteria for treatment of their blood pressure or lipids were not being treated. This is likely at least partly sociologic and partly the general pediatric hesitancy to use medications.”
He said the TODAY team will soon have some new data to show that “glycemia during the early years makes a difference, again supporting intensive intervention early on.”
The TODAY study was supported by grants from the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Zeitler had no further disclosures.

FDA approves first interchangeable biosimilar insulin
The
The approval will allow Semglee to function like a generic drug in the market and may reduce insulin costs.
It is indicated to improve glycemic control in adults and pediatric patients with type 1 diabetes and in adults with type 2 diabetes.
Originally approved in June 2020 as a biosimilar to glargine, Semglee is now an “interchangeable biosimilar,” meaning that it has no clinically meaningful difference from the reference product and also may be substituted for that product – in this case, glargine (Lantus) – without prescriber intervention, just as generic drugs typically are, subject to state pharmacy laws.
For approval as an interchangeable biosimilar, manufacturers are required to provide additional data reflecting how the interchangeable biosimilar may be used in the marketplace with patients.
“Biosimilar and interchangeable biosimilar products have the potential to reduce health care costs, similar to how generic drugs have reduced costs. Biosimilars marketed in the U.S. typically have launched with initial list prices 15% to 35% lower than comparative list prices of the reference products,” the FDA said in a statement.
Semglee comes in 10-mL and 3-mL prefilled pens, and is administered subcutaneously once daily, with individualized doses. The most common side effects are hypoglycemia, edema, lipodystrophy, weight gain, and allergic reactions.
The FDA released new materials for health care providers regarding biosimilar and interchangeable biosimilar products, including a fact sheet about interchangeable biosimilar products.

FDA okays extended-release exenatide for children with T2D
the agency announced July 22.
Previously approved in adults, the injectable is now the second glucagonlike peptide-1 receptor agonist approved for use in pediatric type 2 diabetes, after liraglutide (Victoza, Novo Nordisk) in 2019, and the first with once-weekly administration.
The two extended-release Bydureon products – which differ in delivery device and mixing procedure – are now indicated for use in addition to diet and exercise to improve glycemic control in pediatric patients 10 years of age or older with type 2 diabetes.
Exenatide extended release is not recommended as first-line treatment following diet and exercise.
The approval was based on a 24-week, double-blind, placebo-controlled study in 82 children with type 2 diabetes aged 10 and older. They were randomized to 2 mg once-weekly exenatide extended release or placebo. At week 24, hemoglobin A1c in those randomized to the drug had dropped by 0.25 percentage points, compared with a 0.45 percentage point increase in the placebo group.
Side effects were similar to those seen in adults, including injection site reactions, headaches, and gastrointestinal discomfort.
Currently, metformin is the only oral medication approved for treating pediatric type 2 diabetes, while the injectables also include insulin in addition to the two GLP-1 receptor agonists. During a symposium held in June 2021 at the annual scientific sessions of the American Diabetes Association, speakers expressed alarm about the rise in youth developing type 2 diabetes, noting that the condition typically progresses more rapidly and is less likely to respond well to metformin, compared with adults.
But, the panelists were also optimistic about extended-release exenatide as well as several other therapies for pediatric patients with type 2 diabetes in ongoing phase 3 trials, including the sodium-glucose cotransporter 2 inhibitors dapagliflozin and empagliflozin, and the dipeptidyl peptidase–4 inhibitors alogliptin and linagliptin. Results are expected in the next 1-2 years.

The approval was based on a 24-week, double-blind, placebo-controlled study in 82 children with type 2 diabetes aged 10 and older. They were randomized to 2 mg once-weekly exenatide extended release or placebo. At week 24, hemoglobin A1c in those randomized to the drug had dropped by 0.25 percentage points, compared with a 0.45 percentage point increase in the placebo group.
Side effects were similar to those seen in adults, including injection site reactions, headaches, and gastrointestinal discomfort.
Currently, metformin is the only oral medication approved for treating pediatric type 2 diabetes, while the injectables also include insulin in addition to the two GLP-1 receptor agonists. During a symposium held in June 2021 at the annual scientific sessions of the American Diabetes Association, speakers expressed alarm about the rise in youth developing type 2 diabetes, noting that the condition typically progresses more rapidly and is less likely to respond well to metformin, compared with adults.
But, the panelists were also optimistic about extended-release exenatide as well as several other therapies for pediatric patients with type 2 diabetes in ongoing phase 3 trials, including the sodium-glucose cotransporter 2 inhibitors dapagliflozin and empagliflozin, and the dipeptidyl peptidase–4 inhibitors alogliptin and linagliptin. Results are expected in the next 1-2 years.
FDA OKs spinal cord stimulation for diabetic neuropathy pain
The Food and Drug Administration has approved the first high-frequency spinal cord stimulation (SCS) therapy for treating painful diabetic neuropathy (PDN).
The approval is specific for the treatment of chronic pain associated with PDN using the Nevro’s Senza System with 10 kHz stimulation. It is intended for patients whose pain is refractory to, or who can’t tolerate, conventional medical treatment. According to the company, there are currently about 2.3 million individuals with refractory PDN in the United States.
The 10 kHz device, called HFX, involves minimally invasive epidural implantation of the stimulator device, which delivers mild electrical impulses to the nerves to interrupt pain signal to the brain. Such spinal cord stimulation “is a straightforward, well-established treatment for chronic pain that’s been used for over 30 years,” according to the company, although this is the first approval of the modality specifically for PDN.
Asked to comment, Rodica Pop-Busui MD, PhD, the Larry D. Soderquist Professor in Diabetes at the University of Michigan, Ann Arbor, said that “the approval of the Nevro 10kHz high-frequency spinal cord stimulation to treat pain associated with diabetic neuropathy has the potential for benefit for many patients with diabetes and painful diabetic peripheral neuropathy.”
She noted that, “although there are several other pharmacological agents that currently carry the FDA approval for PDN, this is a condition that is notoriously difficult to treat, particularly when taking into account the actual number needed to treat with a specific agent to achieve a clinically meaningful pain reduction, as well as the spectrum of side effects and drug-drug interactions in a patient population that require many other additional agents to manage diabetes and comorbidities on a daily basis. Thus, this new therapeutic approach besides effective pain reduction has the additional benefit of bypassing drug interactions.” Dr. Pop-Busui was the lead author on the American Diabetes Association’s 2017 position statement on diabetic neuropathy.
She also cautioned, on the other hand, that “it is not very clear yet how easy it will be for all eligible patients to have access to this technology, what will be the actual costs, the insurance coverage, or the acceptance by patients across various sociodemographic backgrounds from the at-large clinical care. However, given the challenges we encounter to treat diabetic neuropathy and particularly the pain associated with it, it is quite encouraging to see that the tools available to help our patients are now broader.”
Both 6-and 12-month results show benefit
The FDA approval was based on 6-month data from a prospective, multicenter, open-label randomized clinical trial published in JAMA Neurology.
Use of the 10-kHz SCS device was compared with conventional treatment alone in 216 patients with PDN refractory to gabapentinoids and at least one other analgesic class and lower limb pain intensity of 5 cm or more on a 10-cm visual analog scale.
The primary endpoint, percentage of participants reporting 50% pain relief or more without worsening of baseline neurologic deficits at 3 months, was met by 5 of 94 (5%) patients in the conventional group, compared with 75 of 95 (79%) with the 10-kHz SCS plus conventional treatment (P < .001).
Infections requiring device explant occurred in two patients in the 10-kHz SCS group (2%).
At 12 months, those in the original SCS group plus 86% of subjects given the option to cross over from the conventional treatment group showed “clear and sustained” benefits of the 10-kHz SCS with regard to lower-limb pain, pain interference with daily living, sleep quality, and activity, Erika Petersen, MD, director of the section of functional and restorative neurosurgery at the University of Arkansas for Medical Sciences, Little Rock , reported at the 2021 annual scientific sessions of the ADA.
Infection was the most common study-related adverse event, affecting 8 of 154 patients with the SCS implants (5.2%). Three resolved with conservative treatment and five (3.2%) required removal of the device.
The patients will be followed for a total of 24 months.
Commercial launch of HFX in the United States will begin immediately, the company said.
Dr. Pop-Busui has received consultant fees in the last 12 months from Averitas Pharma, Boehringer Ingelheim, Nevro, and Novo Nordisk. Dr. Petersen has financial relationships with Nevro, Medtronic, and several other neuromodulator makers.

Cycling linked to longer life in people with type 2 diabetes
Bicycle riding may help people with diabetes live longer, new research suggests.
Among more than 7,000 adults with diabetes in 10 Western European countries followed for about 15 years, those who cycled regularly were significantly less likely to die of any cause or of cardiovascular causes, even after accounting for differences in factors such as sex, age, educational level, diet, comorbidities, and other physical activities.
“The association between cycling and all-cause and CVD [cardiovascular disease] mortality in this study of person[s] with diabetes was of the same magnitude and direction as observed in the healthy population,” wrote Mathias Ried-Larsen, PhD, of the Centre for Physical Activity Research, Rigshospitalet, Copenhagen, and colleagues. The findings were published online July 19, 2021, in JAMA Internal Medicine.
In an accompanying Editor’s Note, JAMA Internal Medicine editor Rita F. Redberg, MD, and two deputy editors said that the new data add to previous studies showing benefits of cycling, compared with other physical activities. “The analysis from Ried-Larsen and colleagues strengthens the epidemiologic data on cycling and strongly suggests that it may contribute directly to longer and healthier lives,” they wrote.
Dr. Redberg, of the University of California, San Francisco, told this news organization: “I think the number of cyclists grew greatly during pandemic, when there was little auto traffic, and people did not want to take public transportation. Cities that add bike lanes, especially protected bike lanes, see an increase in cyclists. I think Americans can cycle more, would enjoy cycling more, and would live longer [by] cycling, to work and for pleasure.”
Dr. Redberg disclosed that she is “an avid cyclist and am currently on a bike ride in Glacier National Park. ... This group [Climate Ride] raises money for more bike lanes, promotes climate change awareness, has paid for solar panels at Glacier, and more.”
However, Dr. Redberg and colleagues also “recognize that cycling requires fitness, a good sense of balance, and the means to purchase a bicycle. We also understand that regular cycling requires living in an area where it is reasonably safe, and we celebrate the installation of more bike lanes, particularly protected lanes, in many cities around the world.”
But, despite the limitations of an observational study and possible selection bias of people who are able to cycle, “it is important to share this evidence for the potentially large health benefits of cycling, which almost surely generalize to persons without diabetes.”
Cycling tied to lower all-cause and CVD mortality
The prospective cohort study included 7,459 adults with diabetes from the European Prospective Investigation into Cancer and Nutrition. All were assessed during 1992-1998 and again in 1996-2011, with a mean follow-up of roughly 15 years. During that time, there were 1,673 deaths from all causes, with 811 attributed to CVD.
Compared with no cycling, those who reported any cycling had a 24% lower risk of death from any cause over a 5-year period, after adjustment for confounders and for other physical activity. The greatest risk reduction was seen in those who reported cycling between 150-299 minutes per week, particularly in CVD mortality.
In a subanalysis of 5,423 individuals with 10.7 years of follow-up, there were 975 all-cause deaths and 429 from CVD. Individuals who began or continued cycling during follow-up experienced reductions of about 35% for both all-cause and CVD mortality, compared with those who never cycled.
Dr. Redberg and colleagues added that “there are environmental benefits to increasing the use of cycling for commuting and other transport because cycling helps to decrease the adverse environmental and health effects of automobile exhaust.”
They concluded: “As avid and/or aspiring cyclists ourselves, we are sold on the mental and physical benefits of getting to work and seeing the world on two wheels, self-propelled, and think it is well worth a try.”
The study work was supported by the Health Research Fund of Instituto de Salud Carlos III; the Spanish regional governments of Andalucía, Asturias, Basque Country, Murcia, and Navarra; and the Catalan Institute of Oncology. The Centre for Physical Activity Research is supported by a grant from TrygFonden. Dr. Ried-Larsen reported personal fees from Novo Nordisk. Dr. Redberg reported receiving grants from Arnold Ventures; the Greenwall Foundation; and the National Heart, Lung, and Blood Institute.

ADA/EASD draft guidance aims to bring adults with type 1 diabetes out of shadows
A new draft consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes (EASD) addresses diagnosis and management of type 1 diabetes in adults.
The impetus for the document comes from the “highly influential” EASD-ADA consensus report on the management of type 2 diabetes, which led to the realization that a comparable document was needed for adults with type 1 diabetes, said writing panel cochair Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles.
“In recent years, there have been rapid advances in the treatment of type 1 diabetes together with a growing recognition of the psychosocial burden of living with [it],” Dr. Peters said.
She noted that although there is already some guidance available for the management of type 1 diabetes in adults, “this gets admixed into broader guidelines, and many of those are mostly derived from data in people with type 2 diabetes.”
The new draft document was coauthored by 14 content experts in type 1 diabetes, with equal numbers from the United States and Europe.
We want to be helpful to clinicians
Topics covered include diagnosis of type 1 diabetes, goals of therapy and glycemic targets, schedule of care, diabetes self-management education and additional behavioral considerations, glucose monitoring, insulin therapy, hypoglycemia, psychosocial care, diabetic ketoacidosis, pancreas and islet cell transplantation, adjunctive therapies, special populations (including pregnant women, older adults, and inpatient management), and emergent/future perspectives, including beta-cell replacement and immunotherapy.
At the end of the document are tables of glycemic targets for adults with type 1 diabetes, schedule of care, nonglycemic factors that alter A1c levels, standardized continuous glucose meter (CGM) metrics for clinical care, examples of subcutaneous insulin regimens, and the various properties of approved and nonapproved adjunctive therapies for type 1 diabetes, including metformin, pramlintide, GLP-1 agonists, and SGLT2 inhibitors.
Several colorful flowcharts are also provided, including algorithms for diagnosing and managing type 1 diabetes in adults.
Document coauthor M. Sue Kirkman, MD, of the Diabetes Care Center’s Clinical Trials Unit at the University of North Carolina, Chapel Hill, told this news organization: “We want it to be helpful to clinicians who are diagnosing type 1 diabetes in adults or caring for adults with type 1 diabetes, whether diagnosed in childhood or adulthood.”
The authors presented an overview of the document in a symposium on June 28 at the virtual ADA scientific sessions. The final version will be presented Oct. 1 at the EASD 2021 annual meeting.
The draft document and video of the ADA meeting presentation are both available on the ADA website.
New algorithm to reduce misdiagnosis of type 1 diabetes in adults
Misdiagnosis of adult-onset type 1 diabetes is common, occurring in up to 40% of those who develop the condition after age 30 years, said J. Hans de Vries, MD, PhD, medical director, Profil Institute for Metabolic Research, Neuss, Germany.
There are multiple reasons for this, including the fact that obesity and type 2 diabetes are becoming more prevalent at younger ages, C-peptide levels may still be relatively high at the time of clinical type 1 diabetes onset, and islet autoantibodies don’t have 100% positive predictive value.
“No single feature confirms type 1 diabetes in isolation,” Dr. de Vries noted.
The document provides a detailed diagnostic algorithm specifically for adults in whom type 1 diabetes is suspected, starting with autoantibody measurement. If the diagnosis isn’t confirmed that way, the algorithm advises investigating for monogenic diabetes, including use of a maturity-onset diabetes of the young (MODY) calculator and subsequent C-peptide measurement.
Measurement of C-peptide is also recommended if the diabetes type is still uncertain more than 3 years after diabetes onset in those treated with insulin, because by that point it is likely to be <200 pmol/L in people with type 1 diabetes.
Clear statements on diabetes technology, preferred insulins
The draft document clearly states that physiologic insulin replacement using a pump or multiple daily injections, CGM, and analog rather than human insulin are standards of care for adults with type 1 diabetes. Use of hybrid closed-loop insulin delivery systems is advised when available, as they offer the “greatest benefits.”
However, the document also notes that in cases of cost barriers, subcutaneous regimens of human regular and NPH insulin may be used. It cautions, though, that these may result in higher glucose variability, higher risk of hypoglycemia, and less lifestyle flexibility.
Dr. Kirkman told this news organization: “Using human insulins such as NPH and Regular in type 1 diabetes is definitely not preferred, but sometimes due to people’s inability to afford analogs we have to use them. People need to know how to use them safely.”
As for the do-it-yourself insulin delivery systems, which many with type 1 diabetes now use with open-source software algorithms that reverse-engineer older pumps, the document advises that health care providers shouldn’t actively recommend them as they’re not approved by regulatory authorities, but should also “respect the individual’s right to make informed choices and continue to offer support,” Dr. Kirkman said when presenting the insulin therapy section.
Psychosocial aspects of type 1 diabetes ‘underappreciated’
Special emphasis is placed on psychosocial support, which may be overlooked in adults, Dr. Kirkman noted.
“Clinicians probably underappreciate what people with type 1 diabetes go through on a daily basis. A lot of the evidence out there regarding psychosocial issues is in children and families of children with type 1 diabetes, or in adults with type 2 diabetes ... Maximizing quality of life needs to be at the forefront of care, not just focusing on glycemic goals.”
Indeed, between 20% and 40% of people with type 1 diabetes experience diabetes-related emotional distress – including 15% with depression – particularly at the time of diagnosis and when complications develop, noted Frank J. Snoek, PhD, professor of medical psychology at Amsterdam University Medical Center, the Netherlands.
To address this, the draft advises that “self-management difficulties, psychological, and social problems” be screened periodically and monitored using validated screening tools.
“Health care providers should be proficient at asking questions about and discussing emotional health, psychological needs, and social challenges as part of the consultation,” Dr. Snoek said.
Dr. Peters disclosed ties with Abbott Diabetes Care, AstraZeneca, Lilly, Medscape, Novo Nordisk, Vertex, and Zealand, Omada, and Teladoc. Dr. Kirkman has received research support from Novo Nordisk and Bayer. Dr. de Vries disclosed ties with Adocia, Novo Nordisk, Zealand, Eli Lilly, and Afon Technology. Dr. Snoek reported ties with Roche Diabetes, Novo Nordisk, Sanofi, and Eli Lilly.

New algorithm to reduce misdiagnosis of type 1 diabetes in adults
Misdiagnosis of adult-onset type 1 diabetes is common, occurring in up to 40% of those who develop the condition after age 30 years, said J. Hans de Vries, MD, PhD, medical director, Profil Institute for Metabolic Research, Neuss, Germany.
There are multiple reasons for this, including the fact that obesity and type 2 diabetes are becoming more prevalent at younger ages, C-peptide levels may still be relatively high at the time of clinical type 1 diabetes onset, and islet autoantibodies don’t have 100% positive predictive value.
“No single feature confirms type 1 diabetes in isolation,” Dr. de Vries noted.
The document provides a detailed diagnostic algorithm specifically for adults in whom type 1 diabetes is suspected, starting with autoantibody measurement. If the diagnosis isn’t confirmed that way, the algorithm advises investigating for monogenic diabetes, including use of a maturity-onset diabetes of the young (MODY) calculator and subsequent C-peptide measurement.
Measurement of C-peptide is also recommended if the diabetes type is still uncertain more than 3 years after diabetes onset in those treated with insulin, because by that point it is likely to be <200 pmol/L in people with type 1 diabetes.
Clear statements on diabetes technology, preferred insulins
The draft document clearly states that physiologic insulin replacement using a pump or multiple daily injections, CGM, and analog rather than human insulin are standards of care for adults with type 1 diabetes. Use of hybrid closed-loop insulin delivery systems is advised when available, as they offer the “greatest benefits.”
However, the document also notes that in cases of cost barriers, subcutaneous regimens of human regular and NPH insulin may be used. It cautions, though, that these may result in higher glucose variability, higher risk of hypoglycemia, and less lifestyle flexibility.
Dr. Kirkman told this news organization: “Using human insulins such as NPH and Regular in type 1 diabetes is definitely not preferred, but sometimes due to people’s inability to afford analogs we have to use them. People need to know how to use them safely.”
As for the do-it-yourself insulin delivery systems, which many with type 1 diabetes now use with open-source software algorithms that reverse-engineer older pumps, the document advises that health care providers shouldn’t actively recommend them as they’re not approved by regulatory authorities, but should also “respect the individual’s right to make informed choices and continue to offer support,” Dr. Kirkman said when presenting the insulin therapy section.
Psychosocial aspects of type 1 diabetes ‘underappreciated’
Special emphasis is placed on psychosocial support, which may be overlooked in adults, Dr. Kirkman noted.
“Clinicians probably underappreciate what people with type 1 diabetes go through on a daily basis. A lot of the evidence out there regarding psychosocial issues is in children and families of children with type 1 diabetes, or in adults with type 2 diabetes ... Maximizing quality of life needs to be at the forefront of care, not just focusing on glycemic goals.”
Indeed, between 20% and 40% of people with type 1 diabetes experience diabetes-related emotional distress – including 15% with depression – particularly at the time of diagnosis and when complications develop, noted Frank J. Snoek, PhD, professor of medical psychology at Amsterdam University Medical Center, the Netherlands.
To address this, the draft advises that “self-management difficulties, psychological, and social problems” be screened periodically and monitored using validated screening tools.
“Health care providers should be proficient at asking questions about and discussing emotional health, psychological needs, and social challenges as part of the consultation,” Dr. Snoek said.

A new draft consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes (EASD) addresses diagnosis and management of type 1 diabetes in adults.
The impetus for the document comes from the “highly influential” EASD-ADA consensus report on the management of type 2 diabetes, which led to the realization that a comparable document was needed for adults with type 1 diabetes, said writing panel cochair Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles.
“In recent years, there have been rapid advances in the treatment of type 1 diabetes together with a growing recognition of the psychosocial burden of living with [it],” Dr. Peters said.
She noted that although there is already some guidance available for the management of type 1 diabetes in adults, “this gets admixed into broader guidelines, and many of those are mostly derived from data in people with type 2 diabetes.”
The new draft document was coauthored by 14 content experts in type 1 diabetes, with equal numbers from the United States and Europe.

Not so crazy: Pancreas transplants in type 2 diabetes rising
Simultaneous
Traditionally, recipients of pancreas transplants have been people with type 1 diabetes who also have either chronic kidney disease (CKD) or hypoglycemic unawareness. The former group could receive either a simultaneous pancreas-kidney or a pancreas after kidney transplant, while the latter – if they have normal kidney function – would be eligible for a pancreas transplant alone.
But increasingly in recent years, patients with type 2 diabetes and CKD have been receiving simultaneous pancreas-kidney transplants, with similar success rates to those of people with type 1 diabetes.
Such candidates are typically sufficiently fit, not morbidly obese, and taking insulin regardless of their C-peptide status, said Jon S. Odorico, MD, professor of surgery and director of pancreas and islet transplantation at the University of Wisconsin–Madison Transplant Program.
“One might ask: Is it a crazy idea to do a pancreas transplant for patients with type 2 diabetes? Based on the known mechanisms of hyperglycemia in these patients, it might seem so,” he said, noting that while individuals with type 2 diabetes usually have insulin resistance, many also have relative or absolute deficiency of insulin production.
“So by replacing beta-cell mass, pancreas transplantation addresses this beta-cell defect mechanism,” he explained when discussing the topic during a symposium held June 26 at the virtual American Diabetes Association (ADA) 81st Scientific Sessions.
Arguments in favor of simultaneous pancreas-kidney transplant in people with type 2 diabetes and CKD include the fact that type 2 diabetes is the leading cause of kidney disease in the United States – roughly 50-60% of candidates on the kidney transplant waiting list also have type 2 diabetes – and that kidney transplant alone tends to worsen diabetes control due to the required immunosuppression.
Moreover, due to a 2014 allocation policy change that separates simultaneous pancreas-kidney from kidney transplant–alone donor organs, waiting times are shorter for the former, and kidney quality is generally better than for kidney transplant alone, unless a living kidney donor is available.
And, Dr. Odorico added, “adding a pancreas to a kidney transplant does not appear to jeopardize patient survival or kidney graft survival in appropriately selected patients with diabetes.” However, he also noted that because type 2 diabetes is so heterogeneous, ideal candidates for simultaneous pancreas-kidney transplant are not yet clear.
Currently, people with type 2 diabetes account for about 20% of those receiving simultaneous pancreas-kidney transplants and about 50% of pancreas after kidney transplants. Few pancreas transplants alone are performed in type 2 diabetes because those individuals rarely experience severe life-threatening hypoglycemia, Dr. Odorico explained.
Criteria have shifted over time, C-peptide removed in 2019
In an interview, symposium moderator Peter G. Stock, MD, PhD, surgical director of the Kidney and Pancreas Transplant Program at the University of California, San Francisco, said he agreed that “it’s a surprising trend. It doesn’t make intuitive sense. In type 1 diabetes, it makes sense to replace the beta cells. But type 2 is due to a whole cluster of etiologies ... The view in the public domain is that it’s not due to the lack of insulin but problems with insulin resistance and obesity. So it doesn’t make a whole lot of sense to give you more insulin if it’s a receptor problem.”
But Dr. Stock noted that because in the past diabetes type wasn’t always rigorously assessed using C-peptide and antibody testing, which most centers measure today, “a number of transplants were done in people who turned out to have type 2. Our perception is that everybody who has type 2 is obese, but that’s not true anymore.”
Once it became apparent that some patients with type 2 diabetes who received pancreas transplants seemed to be doing well, the pancreas transplantation committee of the United Network for Organ Sharing (UNOS) established general criteria for the procedure in people with diabetes. They had to be taking insulin and have a C-peptide value of 2 ng/mL or below or taking insulin with a C-peptide greater than 2 ng/mL and a body mass index less than or equal to the maximum allowable BMI (28 kg/m2 at the time).
Dr. Stock, who chaired that committee from 2005 to 2007, said: “We thought it was risky to offer a scarce pool of donor pancreases to people with type 2 when we had people with type 1 who we know will benefit from it. So initially, the committee decided to limit pancreas transplantation to those with type 2 who have fairly low insulin requirements and BMIs that are more in the range of people with type 1. And lo and behold the results were comparable.”
Subsequent to Dr. Stock’s tenure as chair, the UNOS committee decided that the BMI and C-peptide criteria for simultaneous pancreas-kidney were no longer scientifically justifiable and were potentially discriminatory both to minority populations with type 2 diabetes and people with type 1 diabetes who have a high BMI, so in 2019, they removed them.
Individual transplant centers must follow UNOS rules, but they can also add their own criteria. Some don’t perform simultaneous pancreas-kidney transplants in people with type 2 diabetes at all.
At Dr. Odorico’s center, which began doing so in 2012, patients with type 2 diabetes account for nearly 40% of all simultaneous pancreas-kidney transplants. Indications there include age 20-60 years, insulin dependent with requirements less than 1 unit/kg/day, CKD stage 3-5, predialysis or on dialysis, and BMI <33 kg/m2.
“They are highly selected and a fairly fit group of patients,” Dr. Odorico noted.
Those who don’t meet all the requirements for simultaneous pancreas-kidney transplants may still be eligible for kidney transplant alone, from either a living or deceased donor, he said.
Dr. Stock’s criteria at UCSF are even more stringent for both BMI and insulin requirements.
SPK outcomes similar for type 1 and type 2 diabetes: Emerging data
Data to guide this area are accumulating slowly. Thus far, all studies have been retrospective and have used variable definitions for diabetes type and for graft failure. However, they’re fairly consistent in showing similar outcomes by diabetes type and little impact of C-peptide level on patient survival or survival of either kidney or pancreas graft, particularly after adjustment for confounding factors between the two types.
In a study from Dr. Odorico’s center of 284 type 1 and 39 type 2 diabetes patients undergoing simultaneous pancreas-kidney transplant between 2006 and 2017, pretransplant BMI and insulin requirements did not affect patient or graft survival in either type. There was a suggestion of greater risk for post-transplant diabetes with very high pretransplant insulin requirements (>75 units/day) but the numbers were too small to be definitive.
“It’s clear we will be doing more pancreas transplants in the future in this group of patients, and it’s ripe for further investigation,” Dr. Odorico concluded.
Beta cells for all?
Dr. Stock added one more aspect. While of course whole-organ transplantation is limited by the shortage of human donors, stem cell–derived beta cells could potentially produce an unlimited supply. Both Dr. Stock and Dr. Odorico are working on different approaches to this.
“We’re really close,” he said, noting, “the data we get for people with type 2 diabetes undergoing solid organ pancreas transplant could also be applied to cellular therapy ... We need to get a better understanding of which patients will benefit. The data we have so far are very promising.”
Dr. Odorico is scientific founder, stock equity holder, scientific advisory board chair, and a prior grant support recipient from Regenerative Medical Solutions. He has reported receiving clinical trial support from Veloxis Pharmaceuticals, CareDx, Natera, and Vertex Pharmaceuticals. Dr. Stock has reported being on the scientific advisory board of Encellin and receives funding from the California Institute of Regenerative Medicine and National Institutes of Health.

FDA rejects teplizumab for type 1 diabetes delay
The U.S. , despite narrow endorsement in a 10-7 vote in favor of approval by one of its advisory panels in May.
According to the company, the FDA did not cite any clinical deficiencies related to the efficacy and safety data packages submitted as part of the biologics license application for teplizumab.
Rather, the sticking point appears to be a study in healthy volunteers that had been raised as an issue with Provention Bio in April.
That study was designed to compare the planned commercial product with the product originally manufactured for clinical trials, but the former was not pharmacologically comparable to the latter, the FDA said in its complete response letter, issued on July 2.
The company expects, later this quarter, to obtain data from a substudy in patients receiving 12 days of therapy in the ongoing PROTECT trial of newly diagnosed patients with type 1 diabetes, which it hopes will help alleviate the FDA’s concerns.
“Upon review of the results from this substudy, the company will determine whether to submit these data to the FDA for its review ... to support pharmacokinetic comparability or otherwise justify why pharmacokinetic comparability is not necessary,” it said in its statement.
The FDA’s complete response letter had also mentioned additional issues related to product quality that Provention believes it has or will be able to address in the short term.
Teplizumab delays type 1 diabetes onset by years
Phase 2 data showing that a 14-day teplizumab infusion delayed the onset of type 1 diabetes by 2 years in high-risk relatives of people with the condition were called “game-changing” when presented at the American Diabetes Association 2019 Scientific Sessions and simultaneously published in the New England Journal of Medicine. These were the data considered by the FDA advisory panel in May.
In response to the FDA decision, the type 1 diabetes research and advocacy organization JDRF said: “It is unfortunate that the FDA has not approved teplizumab at this time and instead has requested additional information from the sponsor. We look forward to Provention Bio addressing the issues outlined in the Complete Response Letter and working with the FDA to bring this option to market safely.”
Teplizumab is one of several potential disease-modifying therapies being studied for type 1 diabetes administered either soon after diagnosis or to asymptomatic individuals with high-risk autoantibodies.
“Disease-modifying therapies such as teplizumab will help address the unmet needs of people with type 1 diabetes and those at risk for developing the disease. In the meantime, our organization will continue to support the research of other disease-modifying therapies that put us on the critical pathway to preventing and ultimately curing type 1 diabetes,” JDRF said in a statement.

Omnipod 5 ‘artificial pancreas’ shows benefit in type 1 diabetes
Insulet’s investigational Omnipod 5 automated insulin delivery system improves glycemic control in people with type 1 diabetes aged as young as 2 years, new data suggest.
The Omnipod 5 system combines a tubing-free insulin-filled delivery “Pod” with the Dexcom G6 continuous glucose monitor and an algorithm built into the Pod connecting the two devices via a smartphone app to semiautomate insulin delivery. It is currently under review by the Food and Drug Administration. The company expects to launch it in limited release during the second half of 2021.
Results from a pivotal trial of the system in children aged 2-5.9 years with type 1 diabetes were presented during the annual scientific sessions of the American Diabetes Association.
Follow-up data at 6 months were also presented for another pivotal study of 112 children aged 6-13.9 years and 129 adults aged 14-70 years. Those primary 3-month data were reported earlier this year at the Endocrine Society’s annual meeting and subsequently published online June 7, 2021, in Diabetes Care. Another study presented at ADA looked at quality of life in children using Omnipod 5 and their caregivers.
If approved by the FDA, the Omnipod 5 would be the third commercially available automated insulin delivery system – also called hybrid closed-loop or artificial pancreas systems – in the United States. It would be the second approved for children as young as 2 years of age and the first to deliver insulin subcutaneously without tubing.
‘No-tubing’ feature will be a draw for parents of young children
Asked to comment, pediatric endocrinologist Laura M. Jacobsen, MD, of the University of Florida, Gainesville, said in an interview: “I think the big advantage for the Omnipod 5 is that [if approved it will be] the only tubeless automated insulin delivery system in the U.S.”
“The automated delivery systems have just been wonderful for helping patients achieve time in range, especially overnight. And the fact that this goes down to such a young age where that can be very difficult is wonderful.”
Another difference between the Omnipod 5 and other systems is the ability to adjust glucose targets (from 110 to 150 mg/dL), although newer versions of the currently available hybrid closed-loop systems are expected to include that feature as well. “They’re all slightly different in the way the algorithms work, but I think the end result is similar,” Dr. Jacobsen said.
But, she said, the no-tubing feature might be particularly helpful for some very active young kids. “A lot of small kids do use the tubed pumps, and you can make it work with a lot of kids, but with some kids it just won’t ... the tubing gets caught. I think this really helps parents make the step. A lot of them don’t want to try the tubing whereas they see the Omnipod and might feel a little more confidence to try a pump.”
Overall, said Dr. Jacobsen, who has no financial disclosures with Insulet, Dexcom, or any of their competitors, “I think any addition to the technology field to improve quality of life for people with type 1 diabetes is important and people need choices.”
Pivotal data show benefit in ‘difficult-to-manage’ preschool children
Pivotal 3-month data for the Omnipod 5 in children aged 2-5.9 years with type 1 diabetes were presented on June 26 by pediatric endocrinologist Jennifer Sherr, MD, PhD, Yale University, New Haven, Conn.
“As a pediatric endocrinologist, I can attest to the difficulty of managing this age group, due to grazing eating patterns and erratic physical activity. Oftentimes, care providers may fear hypoglycemia as these youth can not verbalize or self-treat lows,” she remarked.
A total of 80 children were enrolled at 10 institutions across the United Sates. There was a single 14-day standard therapy phase (baseline), followed by 3 months of automated insulin delivery during which the children’s eating and exercise were unrestricted.
At 3 months, average hemoglobin A1c had fallen from 7.4% at baseline to 6.9%, a significant difference (P < .05). The proportions achieving the target A1c of less than 7% were 54% at 3 months versus 31% at baseline. The reduction was even greater among the 25 with baseline A1c of 8% or greater, although it was significant even among the 55 who started with a lower A1c (–1.06 vs. –0.31 percentage points; both P < .05).
Time in range rose from 57.2% at baseline to 68.1% at 3 months (P < .05).
“These youngsters are spending an average of 2.6 more hours/day in range,” Dr. Sherr commented, noting that the difference became apparent shortly after study start and was maintained during the 3 months.
Dr. Sherr noted that this 10.9% improvement in time in range with Omnipod 5 was similar to improvements in the previously reported pivotal study of older children and adults. Data from that study showed improvement in time in range from a gain of 15.6% for the 6 to 13.9 year olds to 8.0% for those aged 26-49 years. Interestingly, improvements in time in range were seen even in the oldest group, aged 50-70, who increased from an already high baseline of 69.9% to 79.1% with Omnipod 5 after 3 months.
In her current study, in the youngest age group, the improvement in time in range was achieved primarily by a reduction of time above range, from 2.4 fewer hours/day above 180 mg/dL, while time below 70 mg/dL was reduced by 4 minutes/day. Overnight time in range improved by 1.4 hours/night, with most of the improvements in reduction of hyperglycemia.
The proportions meeting the combined goals of less than 4% time below range and greater than 60% time in range rose from 29% to 65%.
There were no episodes of severe hypoglycemia or diabetic ketoacidosis during the 3-month study phase.
Another important related metric, sleep quality for parents/caregivers, also improved. The percentage reporting overall sleep quality of “very good” or “fairly good” increased from 65% at baseline to 90% with Omnipod 5, while “very bad” sleep quality fell from 8.8% to 0%.
All 80 patients completed the study and elected to continue in a 12-month extension phase.
Ongoing benefit seen in older children and adults
In a late-breaking poster presented on June 25, Anders L. Carlson, MD, medical director at the International Diabetes Center at Park Nicollet, Minneapolis, presented more follow-up data to the previously reported 3-month pivotal study, including 108 older children and 109 adults from the original study.
A1c remained lower after 6 months than at baseline for both children and adults (P < .001). In the children, A1c levels weren’t significantly different at the end of 6 versus 3 months, while in the adults there was an additional 0.1 percentage point decrease (P < .01).
There was one episode of diabetic ketoacidosis and no severe hypoglycemic episodes in the 3-month extension. “Sustained reduction of A1c indicates the potential long-term benefit of the Omnipod 5 System,” Dr. Carlson and colleagues concluded.
Reduced diabetes distress, don’t forget parents’ quality of life
Meanwhile, psychologist Korey K. Hood, PhD, of Stanford (Calif.) University, presented quality of life data at the meeting for 83 children aged 6-11.9 years and 42 teens aged 12-17.9 years using the Omnipod 5 from the larger study population and their parents.
Significant improvements were seen for both the youth and their caregivers in the Problem Areas in Diabetes score, a measure of diabetes-related emotional distress. Changes were less dramatic on the Hypoglycemic Confidence Scale, although improvements were significant for the caregivers of the younger children.
“We know this is a group that is really worried about hypoglycemia across a lot of situations, not just sleep but also school and outside of the home. So, to increase their confidence to this extent I think is a pretty important finding,” Dr. Hood commented.
There were nonsignificant trends in improvement across groups on the Pittsburgh Sleep Quality Index, but overall sleep quality did significantly improve among parents of the younger children. And on the World Health Organization–5 quality of life survey, significant improvements again were seen among the caregivers of young children.
“Reduced diabetes distress and improved quality of life are key benefits of using the Omnipod 5 [automated insulin delivery] system that are complementary to the glycemic benefits achieved,” Dr. Hood said.
Dr. Jacobsen has reported no relevant financial relationships. Dr. Sherr has reported being an adviser for, consultant for, and/or grant recipient from Bigfoot Biomedical, Cecelia Health, Insulet, Medtronic Diabetes, Eli Lilly, Lexicon, Sanofi, and the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Hood has reported being a consultant for Cecelia Health, Havas, and Cercacor.

“We know this is a group that is really worried about hypoglycemia across a lot of situations, not just sleep but also school and outside of the home. So, to increase their confidence to this extent I think is a pretty important finding,” Dr. Hood commented.
There were nonsignificant trends in improvement across groups on the Pittsburgh Sleep Quality Index, but overall sleep quality did significantly improve among parents of the younger children. And on the World Health Organization–5 quality of life survey, significant improvements again were seen among the caregivers of young children.
“Reduced diabetes distress and improved quality of life are key benefits of using the Omnipod 5 [automated insulin delivery] system that are complementary to the glycemic benefits achieved,” Dr. Hood said.
