TOPLINE:

In insulin-naive people with type 2 diabetes, once-weekly icodec titrated with a dosing guide app was both noninferior and superior to daily basal analogs in reducing A1c levels, with improved treatment satisfaction and compliance scores and similarly low hypoglycemia rates.

METHODOLOGY:

• A 52-week, randomized, open-label, parallel-group, phase 3a trial with real-world elements was conducted at 176 sites in seven countries.
• A total of 1,085 insulin-naive patients with type 2 diabetes were randomly assigned to receive icodec with a dosing guide app or daily analogs (U100 glargine, U300 glargine, or icodec).

TAKEAWAY:

• A1c levels dropped from 8.96% at baseline to 7.24% at week 52 with icodec and from 8.88% to 7.61% with the daily analog, a treatment difference of 0.37 percentage point (P < .001 for noninferiority and P = .009 for superiority in favor of icodec plus the app).
• Patient-reported outcomes were more favorable with icodec plus the app vs. daily analogs, with estimated treatment differences that were significant for the Treatment Related Impact Measure for Diabetes (3.04) but not the Diabetes Treatment Satisfaction Questionnaire (0.78).
• Observed rates of combined clinically significant or severe hypoglycemia were low (0.19 event per patient-year of exposure for icodec plus the app vs. 0.14 for daily analogs; estimated rate ratio, 1.17).

IN PRACTICE:

“Once-weekly icodec with a dosing guide app could conceivably address several challenges seen in everyday practice, including inadequate dose titration and nonadherence to prescribed treatment regimens.”

SOURCE:

The study was conducted by Harpreet S. Bajaj, MD, MPH, of LMC Diabetes and Endocrinology, Brampton, Ontario, and colleagues. It was published online in Annals of Internal Medicine.

LIMITATIONS:

The research could not differentiate between the effects of icodec and those of the dosing guide app. The study had an open-label design. A 1-year duration is insufficient to assess long-term diabetes- and cardiovascular-related outcomes.

DISCLOSURES:

The study was funded by Novo Nordisk A/S.

The complex pathophysiology of obesity requires a multidisciplinary approach that includes lifestyle and medical interventions for successful management. Antiobesity medications (AOMs) have emerged as a powerful and life-changing tool for many individuals with obesity who are unable to sustain long-term weight loss through lifestyle changes alone. As with other chronic diseases such as hypertension and hyperlipidemia, the goal of decades of research has been to develop antiobesity medications with long-term efficacy and safety. Recent groundbreaking findings from a phase 2 trial show immense potential for a new AOM.

Here are five things to know about the role of agonists in the management of obesity.

1. Gut hormone physiology informs the development of AOMs.

The three hormones associated with obesity or diabetes are glucagonlike peptide 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), and glucagon. GLP-1, a peptide released from the intestines in response to food ingestion, increases insulin production, reduces gut motility, and suppresses appetite. GIP is also an intestinal hormone that increases meal-stimulated insulin production and additionally facilitates lipolysis. Glucagon is known to increase hepatic glucose output but will also increase insulin secretion in the setting of hyperglycemia. Glucagon also promotes lipolysis.

Though these hormones are more commonly thought of as incretins, gut hormones that stimulate postprandial insulin secretion, their role in energy physiology is more diverse. Because of multiple mechanisms of action, incretins are increasingly referred to as nutrient-stimulated hormones (NuSH), a term which encompasses other peptides with therapeutic potential (e.g., amylin, oxyntomodulin, peptide tyrosine–tyrosine).

2. Studies have shown that NuSH therapies are highly effective AOMs.

In 2021 the Food and Drug Administration approved subcutaneous semaglutide 2.4 mg, a GLP-1 receptor agonist, for the treatment of obesity. Clinical trials demonstrating an average weight loss of 15% in patients taking semaglutide ushered in a new era of AOMs associated with significant weight loss that not only improve disease activity but also have the potential to achieve diabetes remission. Recent findings from the OASIS I trial demonstrated an average weight loss of 15.1% from baseline in patients treated with oral semaglutide for 68 weeks. Medical societies, including the American Diabetes Association and the American Association for the Study of Liver Diseases, recommend 10%-15% weight loss to fully treat weight-related comorbidities like type 2 diabetes and nonalcoholic fatty liver disease. In 2022, tirzepatide, a dual GLP-1 and GIP receptor agonist, demonstrated an average weight loss of 22.5% in phase 3 of the SURMOUNT-1 trial for obesity – a weight loss approaching that of some bariatric surgeries.

3. Clinical trial data show that the novel triple agonist retatrutide induces significant weight loss.

Preclinical studies on the newest NuSH therapy, triple GLP-1–GIP–glucagon receptor agonist retatrutide, showed predominant activity at the GIP receptor, with less GLP-1– and glucagon-receptor agonism than that of endogenous GLP-1 and GIP. Results from a phase 2 trial published in June 2023 showed a weight loss of 24% at 48 weeks in adults with obesity treated with retatrutide, which is the greatest weight loss reported in an obesity trial so far. Moreover, for the first time in obesity pharmacotherapy research, 100% of participants achieved clinically significant weight loss (defined as ≥ 5% of baseline weight).

4. Retatrutide may improve lipid metabolism.

In the phase 2 trial, retatrutide reduced low-density lipoprotein cholesterol levels by approximately 20%. This degree of reduced plasma LDL-C is dramatic in weight loss studies. Typically, weight loss significantly reduces triglyceride levels, increases high-density lipoprotein cholesterol levels, and has a modest effect on LDL-C reduction of about 5%.

A 20% reduction in LDL-C with retatrutide is hypothesis generating. Preclinical studies have shown glucagon to be an important regulator of proprotein convertase subtilisin/kexin type 9 degradation, with the lack of glucagon resulting in increased PCSK9 levels, decreased LDL receptors, and increased plasma LDL; conversely, treatment with glucagon decreased plasma LDL.

5. The long-term safety of retatrutide still needs to be determined.

In the 48-week phase 2 trial, retatrutide was observed to have a side-effect profile largely similar to other NuSH therapies (e.g., semaglutide 2.4 mg, tirzepatide), with a predominance of gastrointestinal symptoms including nausea, diarrhea, vomiting, and constipation. However, side effects potentially unique to retatrutide also emerged. Cutaneous hyperesthesia and skin sensitivity were reported in 7% of participants in the retatrutide group vs. 1% in the placebo group; none of these effects were associated with physical skin findings. Of note, 17 out of 198 (9%) participants in the retatrutide group developed cardiac arrhythmia vs. two out of 70 (3%) in the placebo group. There was no consistent pattern of arrhythmia type (e.g., supraventricular, ventricular) observed, and some of these events were reported as “palpitations” or “increased heart rate” without further detail. Phase 3 clinical trial data will provide further insight into the long-term safety of retatrutide.

Vitamin D deficiency appears to render people more vulnerable to canagliflozin’s adverse effects on bone health, whereas vitamin D3 supplementation appears protective of individuals with vitamin D deficiency.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are beneficial for treating type 2 diabetes and reducing cardiovascular and kidney disease risk. However, some, but not all, trial data have linked the SLGT2 inhibitor canagliflozin to increased fracture risk. That particular agent has been reported to accelerate loss of bone mineral density, which could contribute to fracture risk. Other drugs in the class have also been implicated in worsening markers of bone health.

Antidiabetic drug tirzepatide (Mounjaro) shows superiority over semaglutide (Ozempic, Wegovy, and Rybelsus) in controlling blood glucose as well as in the amount of weight lost, results from a meta-analysis of 22 randomized controlled trials show.

“The results indicate tirzepatide’s superior performance over subcutaneous semaglutide in managing blood sugar and achieving weight loss, making it a promising option in the pharmaceutical management of type 2 diabetes,” first author Thomas Karagiannis, MD, PhD, Aristotle University of Thessaloniki, Greece, said in an interview.

“In clinical context, the most potent doses of each drug revealed a clear difference regarding weight loss, with tirzepatide resulting in an average weight reduction that exceeded that of semaglutide by 5.7 kg (12.6 pounds),” he said.

The study is scheduled to be presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in early October.

While a multitude of studies have been conducted for tirzepatide, a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 (GLP-1) receptor agonist, and semaglutide, a selective GLP-1 agonist, studies comparing the two drugs directly are lacking.

For a more comprehensive understanding of how the drugs compare, Dr. Karagiannis and colleagues conducted the meta-analysis of 22 trials, including two direct comparisons, the SURPASS-2 trial and a smaller trial, and 20 other studies comparing either semaglutide or tirzepatide with a common comparator, such as placebo, basal insulin, or other GLP-RA-1 drugs.

Overall, 18,472 participants were included in the studies.

All included studies had assessed a maintenance dose of tirzepatide of either 5, 10, or 15 mg once weekly or semaglutide at doses of 0.5, 1.0, or 2.0 mg once weekly for at least 12 weeks. All comparisons were for subcutaneous injection formulations (semaglutide can also be taken orally).
 

Blood glucose reduction

Tirzepatide at 15 mg was found to have the highest efficacy in the reduction of A1c compared with placebo, with a mean difference of –2.00%, followed by tirzepatide 10 mg (–1.86%) and semaglutide 2.0 mg (–1.62%).

All three of the tirzepatide doses had greater reductions in A1c compared with the respective low, medium, and high doses of semaglutide.

Dr. Karagiannis noted that the differences are significant: “An A1c reduction even by 0.5% is often deemed clinically important,” he said.
 

Body weight reduction comparisons

The reductions in body weight across the three drug doses were greater with tirzepatide (–10.96 kg [24.2 pounds], –8.75 kg [19.3 pounds], and –6.16 kg [13.6 pounds] for 15, 10, and 5 mg, respectively) compared with semaglutide (–5.24 kg [11.6 pounds], –4.44 kg [9.8 pounds], and –2.72 kg [6 pounds] for semaglutide 2.0, 1.0, and 0.5 mg, respectively).

In terms of drug-to-drug comparisons, tirzepatide 15 mg had a mean of 5.72 kg (12.6 pounds) greater reduction in body weight vs. semaglutide 2.0 mg; tirzepatide 10 mg had a mean of 3.52 kg (7.8 pounds) reduction vs. semaglutide 2.0 mg; and tirzepatide 5 mg had a mean of a 1.72 kg (3.8 pounds) greater reduction vs. semaglutide 1.0 mg.
 

Adverse events: Increased GI events with highest tirzepatide dose

Regarding the gastrointestinal adverse events associated with the drugs, tirzepatide 15 mg had the highest rate of the two drugs at their various doses, with a risk ratio (RR) of 3.57 compared with placebo for nausea, an RR of 4.35 for vomiting, and 2.04 for diarrhea.

There were no significant differences between the two drugs for the gastrointestinal events, with the exception of the highest dose of tirzepatide, 15 mg, which had a higher risk of vomiting vs. semaglutide 1.0 (RR 1.39) and semaglutide 0.5 mg (RR 1.85).

In addition, tirzepatide 15 mg had a higher risk vs. semaglutide 0.5 mg for nausea (RR 1.45).

There were no significant differences between the two drugs and placebo in the risk of serious adverse events.
 

Real-world applications, comparisons

Dr. Karagiannis noted that the results indicate that benefits of the efficacy of the higher tirzepatide dose need to be balanced with those potential side effects.

“Although the efficacy of the high tirzepatide dose might make it a favorable choice, its real-world application can be affected on an individual’s ability to tolerate these side effects in case they occur,” he explained.

Ultimately, “some patients may prioritize tolerability over enhanced efficacy,” he added.

Furthermore, while all three maintenance doses of tirzepatide analyzed have received marketing authorization, “to get a clearer picture of the real-world tolerance to these doses outside the context of randomized controlled trials, well-designed observational studies would be necessary,” Dr. Karagiannis said.

Among other issues of comparison with the two drugs is cost.

In a recent analysis, the cost per 1% of body weight reduction was reported to be $1,197 for high-dose tirzepatide (15 mg) vs. $1,511 for semaglutide 2.4 mg, with an overall cost of 72 weeks of therapy with tirzepatide at $17,527 compared with $22,878 for semaglutide.

Overall, patients and clinicians should consider the full range of differences and similarities between the medications, “from [their] efficacy and side effects to cost-effectiveness, long-term safety, and cardiovascular profile,” Dr. Karagiannis said.

Semaglutide is currently approved by the Food and Drug Administration for treatment of type 2 diabetes and obesity/weight loss management.

Tirzepatide has also received approval for the treatment of type 2 diabetes and its manufacturers have submitted applications for its approval for obesity/weight loss management.

Dr. Karagiannis reports no relevant financial relationships.

Tirzepatide at 15 mg was found to have the highest efficacy in the reduction of A1c compared with placebo, with a mean difference of –2.00%, followed by tirzepatide 10 mg (–1.86%) and semaglutide 2.0 mg (–1.62%).

All three of the tirzepatide doses had greater reductions in A1c compared with the respective low, medium, and high doses of semaglutide.

Dr. Karagiannis noted that the differences are significant: “An A1c reduction even by 0.5% is often deemed clinically important,” he said.
 

Body weight reduction comparisons

The reductions in body weight across the three drug doses were greater with tirzepatide (–10.96 kg [24.2 pounds], –8.75 kg [19.3 pounds], and –6.16 kg [13.6 pounds] for 15, 10, and 5 mg, respectively) compared with semaglutide (–5.24 kg [11.6 pounds], –4.44 kg [9.8 pounds], and –2.72 kg [6 pounds] for semaglutide 2.0, 1.0, and 0.5 mg, respectively).

In terms of drug-to-drug comparisons, tirzepatide 15 mg had a mean of 5.72 kg (12.6 pounds) greater reduction in body weight vs. semaglutide 2.0 mg; tirzepatide 10 mg had a mean of 3.52 kg (7.8 pounds) reduction vs. semaglutide 2.0 mg; and tirzepatide 5 mg had a mean of a 1.72 kg (3.8 pounds) greater reduction vs. semaglutide 1.0 mg.
 

Adverse events: Increased GI events with highest tirzepatide dose

Regarding the gastrointestinal adverse events associated with the drugs, tirzepatide 15 mg had the highest rate of the two drugs at their various doses, with a risk ratio (RR) of 3.57 compared with placebo for nausea, an RR of 4.35 for vomiting, and 2.04 for diarrhea.

There were no significant differences between the two drugs for the gastrointestinal events, with the exception of the highest dose of tirzepatide, 15 mg, which had a higher risk of vomiting vs. semaglutide 1.0 (RR 1.39) and semaglutide 0.5 mg (RR 1.85).

In addition, tirzepatide 15 mg had a higher risk vs. semaglutide 0.5 mg for nausea (RR 1.45).

There were no significant differences between the two drugs and placebo in the risk of serious adverse events.
 

Real-world applications, comparisons

Dr. Karagiannis noted that the results indicate that benefits of the efficacy of the higher tirzepatide dose need to be balanced with those potential side effects.

“Although the efficacy of the high tirzepatide dose might make it a favorable choice, its real-world application can be affected on an individual’s ability to tolerate these side effects in case they occur,” he explained.

Ultimately, “some patients may prioritize tolerability over enhanced efficacy,” he added.

Furthermore, while all three maintenance doses of tirzepatide analyzed have received marketing authorization, “to get a clearer picture of the real-world tolerance to these doses outside the context of randomized controlled trials, well-designed observational studies would be necessary,” Dr. Karagiannis said.

Among other issues of comparison with the two drugs is cost.

In a recent analysis, the cost per 1% of body weight reduction was reported to be $1,197 for high-dose tirzepatide (15 mg) vs. $1,511 for semaglutide 2.4 mg, with an overall cost of 72 weeks of therapy with tirzepatide at $17,527 compared with $22,878 for semaglutide.

Overall, patients and clinicians should consider the full range of differences and similarities between the medications, “from [their] efficacy and side effects to cost-effectiveness, long-term safety, and cardiovascular profile,” Dr. Karagiannis said.

Semaglutide is currently approved by the Food and Drug Administration for treatment of type 2 diabetes and obesity/weight loss management.

Tirzepatide has also received approval for the treatment of type 2 diabetes and its manufacturers have submitted applications for its approval for obesity/weight loss management.

Dr. Karagiannis reports no relevant financial relationships.

Antidiabetic drug tirzepatide (Mounjaro) shows superiority over semaglutide (Ozempic, Wegovy, and Rybelsus) in controlling blood glucose as well as in the amount of weight lost, results from a meta-analysis of 22 randomized controlled trials show.

“The results indicate tirzepatide’s superior performance over subcutaneous semaglutide in managing blood sugar and achieving weight loss, making it a promising option in the pharmaceutical management of type 2 diabetes,” first author Thomas Karagiannis, MD, PhD, Aristotle University of Thessaloniki, Greece, said in an interview.

“In clinical context, the most potent doses of each drug revealed a clear difference regarding weight loss, with tirzepatide resulting in an average weight reduction that exceeded that of semaglutide by 5.7 kg (12.6 pounds),” he said.

The study is scheduled to be presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in early October.

While a multitude of studies have been conducted for tirzepatide, a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 (GLP-1) receptor agonist, and semaglutide, a selective GLP-1 agonist, studies comparing the two drugs directly are lacking.

For a more comprehensive understanding of how the drugs compare, Dr. Karagiannis and colleagues conducted the meta-analysis of 22 trials, including two direct comparisons, the SURPASS-2 trial and a smaller trial, and 20 other studies comparing either semaglutide or tirzepatide with a common comparator, such as placebo, basal insulin, or other GLP-RA-1 drugs.

Overall, 18,472 participants were included in the studies.

All included studies had assessed a maintenance dose of tirzepatide of either 5, 10, or 15 mg once weekly or semaglutide at doses of 0.5, 1.0, or 2.0 mg once weekly for at least 12 weeks. All comparisons were for subcutaneous injection formulations (semaglutide can also be taken orally).

AMSTERDAM – Calculating a patient’s myocardial performance index (MPI) and adding it to a standard risk-prediction model significantly increased prognostic accuracy for major adverse cardiovascular events (MACE), especially heart failure, in people with type 1 but not type 2 diabetes, an analysis of data from about 2,000 Danish patients shows.

“MPI provides incremental prognostic information” in people with type 1 diabetes that “may enhance risk prediction” for their future risk of all-cause death, acute coronary syndrome, heart failure, or stroke, Hashmat S.Z. Bahrami, MD, said at the annual congress of the European Society of Cardiology.

The primary analysis he reported showed a significantly elevated adjusted hazard ratio of 1.2 among people with either type 1 or type 2 diabetes and an elevated MPI, compared with those with diabetes but a lower MPI value.

Further analysis divided the study cohort into the 1,093 people with type 1 diabetes and the 1,030 with type 2 diabetes and showed that the significant association of elevated MPI with increased MACE was entirely confined to the type 1 diabetes subgroup, again with a hazard ratio of 1.2, but without any significant association among those with type 2 diabetes, said Dr. Bahrami, a cardiology researcher at Copenhagen University Hospital.
 

‘Trying to figure out’ the type 1 diabetes link

“We’re still trying to figure out” the explanation for this difference based on diabetes type, Dr. Bahrami said. He speculated that it might relate to a higher incidence of heart failure among those with type 1 diabetes, or to longer duration of diabetes in the type 1 subgroup.

The ability of elevated MPI to predict an increased risk specifically for heart failure was apparent in another analysis he presented that divided MACE events into the individual components of this composite. Elevated MPI significantly linked with a 1.3-fold elevated risk for heart failure in those with type 1 diabetes, but high MPI had no significant association with any of the other event types included in the MACE composite.

The researchers also assessed the incremental impact from adding MPI data to an established cardiovascular disease (CVD) risk calculator for people with type 1 diabetes, the Steno Type 1 Risk Engine, which includes nine parameters such as age, sex, blood pressure, diabetes duration, and two different measures of renal function.

This analysis showed that adding MPI significantly boosted the attributable CVD risk from an area-under-the-curve of 0.77 to an AUC of 0.79. Including MPI also boosted the AUC for risk of future heart failure from 0.77 with the existing Steno Type 1 Risk Engine to 0.83, also a significant increase.

Simultaneously with his talk at the Congress, a report on the findings was published online in the European Heart Journal Cardiovascular Imaging.
 

MPI reflects left ventricular function

MPI is calculated by adding a person’s isovolumic cardiac relaxation time to their isovolumic cardiac contraction time and dividing this by their ejection time. These time measurements come from examination with tissue Doppler M-mode echocardiography, Dr. Bahrami explained, and when assessed together reflect left ventricular function during both systolic and diastolic phases.

“MPI has been around for many years, but our technique is rather novel” and has high intra- and inter-observer reproducibility, he said. “It’s highly reproducible and feasible.”

The study included data collected prospectively from Danish adults without any known CVD enrolled in the Thousand & 1 study of people with type 1 diabetes and the Thousand & 2 study of people with type 2 diabetes. The analyses that Dr. Bahrami reported included CVD events during a median 5.3 years of follow-up.

The study received funding from Novo Nordisk. Dr. Bahrami has disclosed no relevant financial relationships.

Women with premenstrual disorders may be more likely go through menopause before they are 45 years old, a new study suggests. 

Women with premenstrual disorders, or PMDs, were also more likely to have moderate or severe night sweats or hot flashes during menopause, the researchers found.

Published in JAMA Network Open, the new findings stem from data from more than 3,600 nurses who contributed their health information to a database between 1991 and 2017. Women with PMDs were more than twice as likely as women without PMDs to have early menopause.

Most women have menopause between the ages of 45 and 55 years old, according to the World Health Organization. 

There are numerous PMDs, including the well-known premenstrual syndrome, which is considered a mild disorder affecting up to 30% of women that causes symptoms like crankiness and bloating. A less common PMD is premenstrual dysphoric disorder, which can severely impact a woman’s life through psychological, gastrointestinal, skin, and neurological problems.

Previous research has linked PMDs during the reproductive years and postmenopausal issues like hot flashes and night sweats to increased risks of health problems like high blood pressure, heart conditions, and diabetes.

“It is important to identify women at risk for early menopause because of its link with poorer heart, brain, and bone health,” Stephanie Faubion, MD, MBA, a doctor at the Mayo Clinic and medical director of the North American Menopause Society, told CNN. Dr. Faubion was not involved in the study.

That said, it’s important to note that the study was observational – meaning researchers can’t say for certain that PMDs will cause early menopause. Rather, the study shows there may be a correlation between the two, Donghao Lu, MD, an associate professor in the department of medical epidemiology and biostatistics at the Karolinska Institute, told CNN.

A small, nonmechanical, implanted device that continuously releases the glucagon-like peptide-1 (GLP-1) receptor agonist exenatide (Byetta, Bydureon) and designed for improving glucose control in people with type 2 diabetes received a resounding, unanimous rejection Sept. 21 from an advisory committee of the Food and Drug Administration.

The 19 voting panel members mostly cited concerning signals of both renal toxicity in the form of excess episodes of acute kidney injury (AKI) as well as increased cardiovascular events compared with placebo as their main reasons for voting that the developing company, Intarcia Therapeutics, had not shown adequate evidence that the benefits of the drug-device combination, known as ITCA 650, outweighed its risks for treating people with type 2 diabetes.

“I’m quite uncomfortable with the AKI safety,” said panel member Erica Brittain, PhD, deputy chief of the Biostatistics Research Branch of the National Institute of Allergy and Infectious Diseases in Bethesda, Md.

The case that ITCA 650 is ready for routine use was also undermined by uncertainty documented by FDA staff about the uniformity and reliability of exenatide delivery by the DUROS device, a matchstick-sized reservoir that’s placed subcutaneously and designed to deliver exenatide continuously for 6 months at a time, noted Cecilia C. Low Wang, MD, chair of the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee.
 

“No evidence of improved adherence”

Another shortcoming was no data on the impact that this form of drug delivery, first developed and FDA approved to treat patients with prostate cancer with leuprolide acetate, really accomplished its goal of improving adherence to a glycemic-control agent. Intarcia Therapeutics presented “no evidence of improved adherence,” said Dr. Low Wang, director of the Glucose Management Team at the University of Colorado Hospital.

However, she and several other panel members acknowledged the compelling comments from several patients and health care professionals experienced in using or administering the device who, during the public comment period, voiced anecdotal testimonials to its positive impact on treatment compliance.
 

Seven years of FDA review

This review of ITCA 650 capped a nearly 7-year effort by Intarcia Therapeutics to receive marketing approval for ITCA 650 from the FDA, which began with an application filed in November 2016 (and denied by the agency in September 2017). Intarcia resubmitted an amended application in 2019 that the FDA again rejected in 2020. The company’s persistence following that led to the current panel meeting, the first time the ITCA 650 evidence came before an advisory panel.

Committee members in general praised the concept of managing blood glucose by continuous release of a medication 6 months at a time. They also offered ideas on a path forward, such as a study that used an active competitor. Ideally, that could be another agent from the same class of GLP-1 receptor agonists such as Bydureon, an injected formulation of exenatide administered by subcutaneous injection once a week. 

But the key, agreed panel members, was to bulk up the evidence that ITCA 650 is safe. “The data show concerning safety signals that need further investigation,” summed up Dr. Low Wong. “There are concerns about overall safety, all-cause mortality, AKI, cardiovascular events, and glycemic excursions.”

All voting members of the advisory committee met the FDA’s standard for having no relevant financial relationships.

But the key, agreed panel members, was to bulk up the evidence that ITCA 650 is safe. “The data show concerning safety signals that need further investigation,” summed up Dr. Low Wong. “There are concerns about overall safety, all-cause mortality, AKI, cardiovascular events, and glycemic excursions.”

All voting members of the advisory committee met the FDA’s standard for having no relevant financial relationships.

A small, nonmechanical, implanted device that continuously releases the glucagon-like peptide-1 (GLP-1) receptor agonist exenatide (Byetta, Bydureon) and designed for improving glucose control in people with type 2 diabetes received a resounding, unanimous rejection Sept. 21 from an advisory committee of the Food and Drug Administration.

The 19 voting panel members mostly cited concerning signals of both renal toxicity in the form of excess episodes of acute kidney injury (AKI) as well as increased cardiovascular events compared with placebo as their main reasons for voting that the developing company, Intarcia Therapeutics, had not shown adequate evidence that the benefits of the drug-device combination, known as ITCA 650, outweighed its risks for treating people with type 2 diabetes.

“I’m quite uncomfortable with the AKI safety,” said panel member Erica Brittain, PhD, deputy chief of the Biostatistics Research Branch of the National Institute of Allergy and Infectious Diseases in Bethesda, Md.

The case that ITCA 650 is ready for routine use was also undermined by uncertainty documented by FDA staff about the uniformity and reliability of exenatide delivery by the DUROS device, a matchstick-sized reservoir that’s placed subcutaneously and designed to deliver exenatide continuously for 6 months at a time, noted Cecilia C. Low Wang, MD, chair of the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee.
 

“No evidence of improved adherence”

Another shortcoming was no data on the impact that this form of drug delivery, first developed and FDA approved to treat patients with prostate cancer with leuprolide acetate, really accomplished its goal of improving adherence to a glycemic-control agent. Intarcia Therapeutics presented “no evidence of improved adherence,” said Dr. Low Wang, director of the Glucose Management Team at the University of Colorado Hospital.

However, she and several other panel members acknowledged the compelling comments from several patients and health care professionals experienced in using or administering the device who, during the public comment period, voiced anecdotal testimonials to its positive impact on treatment compliance.
 

Seven years of FDA review

This review of ITCA 650 capped a nearly 7-year effort by Intarcia Therapeutics to receive marketing approval for ITCA 650 from the FDA, which began with an application filed in November 2016 (and denied by the agency in September 2017). Intarcia resubmitted an amended application in 2019 that the FDA again rejected in 2020. The company’s persistence following that led to the current panel meeting, the first time the ITCA 650 evidence came before an advisory panel.

Committee members in general praised the concept of managing blood glucose by continuous release of a medication 6 months at a time. They also offered ideas on a path forward, such as a study that used an active competitor. Ideally, that could be another agent from the same class of GLP-1 receptor agonists such as Bydureon, an injected formulation of exenatide administered by subcutaneous injection once a week. 

But the key, agreed panel members, was to bulk up the evidence that ITCA 650 is safe. “The data show concerning safety signals that need further investigation,” summed up Dr. Low Wong. “There are concerns about overall safety, all-cause mortality, AKI, cardiovascular events, and glycemic excursions.”

Exercising in the morning may have the biggest impact on the likelihood of having obesity, whereas morning and afternoon exercise appear to reduce the risk of developing type 2 diabetes, suggest two studies.

Tongyu Ma, PhD, research assistant professor with the Health Sciences Department, Franklin Pierce University, Rindge, N.H., and colleagues studied data on almost 5,300 individuals, finding a strong association between moderate to vigorous physical activity (MVPA) and obesity.

The research, published in Obesity, showed that people who exercised in the morning had a lower body mass index than that of those who exercised at other times, even though they were more sedentary.

For the second study, Chirag J. Patel, PhD, associate professor of biomedical informatics at Harvard Medical School, Boston, and colleagues examined more than 93,000 individuals and found that morning and afternoon, but not evening, exercise reduced the risk for type 2 diabetes.

However, the results, published in Diabetologia, also indicated that people who undertook at least MVPA were protected against developing type 2 diabetes no matter what time of day they exercised.

Along with considering the timing of exercise, the authors suggest that it is “helpful to include some higher intensity activity to help reduce the risk of developing diabetes and other cardiovascular disease.”
 

Morning exercisers perform less physical activity

Dr. Ma and colleagues noted that “although a beneficial association among the levels of physical activity with obesity has been frequently reported, the optimal timing of physical activity for decreasing obesity remains controversial.”

The researchers analyzed data from the National Health and Nutrition Examination Survey for the 2003-2004 and 2005-2006 cycles, because accelerometry was implemented in those periods.

They included 5,285 individuals aged ≥ 20 years who had physical activity measured via an accelerometer worn on the right hip during waking hours for 7 consecutive days.

The diurnal pattern of MVPA was classified into three clusters by the established technique of K-means clustering analysis: morning (n = 642), midday (n = 2,456), and evening (n = 2,187).

The association between MVPA, diurnal pattern, and obesity was then assessed in linear regression models taking into account a range of potential confounding factors.

Overall, participants in the morning cluster were older and more likely to be female than those in the other clusters (P < .001 for both). They were also more likely to be nonsmokers (P = .007) and to have less than high school education (P = .0041).

Morning cluster individuals performed less physical activity and were more sedentary than those in the midday and evening groups (P < .001 for both), although they were more likely to be healthy eaters (P = .004), with a lower calorie intake (P < .001).

Individuals in the morning cluster had, on average, a lower body mass index than those in other clusters, at 27.4 vs. 28.4 in the midday cluster and 28.2 in the evening cluster (P for interaction = .02).

Morning cluster participants also had a lower waist circumference than participants in the midday or evening cluster: 95.9 cm, 97.9 cm, and 97.3 cm, respectively (P for interaction = .06).

The team reported that there was a strong linear association between MVPA and obesity in the morning cluster, whereas there was a weaker curvilinear association in the midday and evening clusters.

“This is exciting new research that is consistent with a common tip for meeting exercise goals – that is, schedule exercise in the morning before emails, phone calls, or meetings that might distract you,” Rebecca Krukowski, PhD, professor, public health sciences, University of Virginia, Charlottesville, said in a release.

However, she noted that the cross-sectional nature of the study means that it is “not known whether people who exercise consistently in the morning may be systematically different from those who exercise at other times, in ways that were not measured in this study.

“For example, people who exercise regularly in the morning could have more predictable schedules, such as being less likely to be shift workers or less likely to have caregiving responsibilities that impede morning exercise,” said Dr. Krukowski, who was not involved in the study.
 

No association between evening activity and type 2 diabetes risk

In the second study, the team studied 93,095 persons in the UK Biobank, with a mean age of 62 years and no history of type 2 diabetes, who wore a wrist accelerometer for 1 week.

The movement data were used to estimate the metabolic equivalent of task, which was then summed into the total physical activity completed in the morning, afternoon, and evening and linked to the development of incident type 2 diabetes.

After adjustment for potential confounding factors, both morning and afternoon physical activity were associated with a reduced risk of developing type 2 diabetes, at hazard ratios of 0.90 (P = 7 × 10-8) and 0.91 (P = 1 × 10-5), respectively.

However, there was no association between evening activity and the risk for type 2 diabetes, at a hazard ratio of 0.95 (P = .07).

The team found, however, that MVPA and vigorous physical activity were associated with a reduced risk for type 2 diabetes at all times of day.

Dr. Patel’s study was supported in part by National Institutes of Health grants. No other funding was declared. No relevant financial relationships were declared.

A significant mortality gap persists between patients with type 2 diabetes and cardiovascular disease and similarly aged patients with neither condition. Data from the Emerging Risk Factors Collaboration showed that on average, a 60-year-old female patient with type 2 diabetes and a history of myocardial infarction dies around 14 years earlier than a similarly aged patient with neither of these conditions.

Therefore, I was keen to hear the key new recommendations from the 2023 European Society of Cardiology (ESC) guidelines for the management of cardiovascular disease in patients with diabetes. These recommendations were presented at the recent ESC 2023 congress in Amsterdam, which I was fortunate enough to attend.

The comprehensive guideline cemented the fact that our primary goal in type 2 diabetes management is a reduction in cardiovascular events and mortality, rather than the glucocentric goals that have been followed previously. Of course, good glycemic control remains important to protect against the microvascular complications of diabetes, but glycemic control has only a modest impact on macrovascular complications such as cardiovascular disease.

The updated guideline recommends that all patients with type 2 diabetes without symptomatic atherosclerotic cardiovascular disease or severe target-organ damage be screened for the risk for cardiovascular disease using a new 10-year cardiovascular risk calculator called SCORE2-Diabetes. This calculator extends the well-established SCORE2 cardiovascular risk-prediction tool with added predictors specifically related to type 2 diabetes. It also accounts for variation in risk across Europe.

Using SCORE2 Diabetes will be a change in practice for me, as I have been using QRISK3, which is a United Kingdom–based cardiovascular risk tool that has been less extensively validated in patients with type 2 diabetes. Helpfully, an ESC CVD Risk Calculation app is available and can be tailored to your geographical region to calculate a SCORE2-Diabetes risk score easily. For example, Eastern Europe has a higher cardiovascular risk profile than Western Europe.

Cardiovascular risk categories are now defined on the basis of the presence of atherosclerotic cardiovascular disease, severe target-organ damage, or the 10-year cardiovascular risk using SCORE2-Diabetes.

For patients at very high cardiovascular risk (for example, those with type 2 diabetes and established atherosclerotic cardiovascular disease), the ESC guidance recommends dual therapy with a GLP-1 receptor agonist and an SGLT2 inhibitor to reduce cardiovascular risk independent of glucose control (that is, A1c). This dual therapy is recommended in addition to standard-of-care antiplatelet, antihypertensive, and lipid-lowering therapies.

There is no doubt that the evidence for GLP-1 receptor agonist use and reduction in atherosclerotic cardiovascular disease in type 2 diabetes is compelling, perhaps more so than the evidence for SGLT2 inhibitor use. However, this recommendation will be challenging to implement, given the current global supply issues with GLP-1 receptor agonists, which are driven by the off-label use of these medications for the management of obesity. GLP-1 receptor agonist supplies are not expected to stabilize until mid-2024.

Controversially, the updated ESC guidance suggests the use of metformin only in patients with type 2 diabetes and atherosclerotic cardiovascular disease if additional glucose control is required. This is a misstep, in my opinion, as insulin resistance is one of the key pathophysiologic abnormalities in patients with type 2 diabetes. One of the key advantages of metformin is an improvement in insulin sensitivity. This recommendation will not change my practice, and I will continue to prescribe metformin alongside GLP-1 receptor agonists or SGLT2 inhibitors for my patients at highest cardiovascular risk.

The updated ESC guidance also explicitly reminds healthcare professionals to look for significant comorbidities, such as heart failure of all subtypes and chronic kidney disease.

The ESC guidance recommends a systematic survey for heart failure symptoms and signs at each clinical encounter in all patients with type 2 diabetes. Although I agree that heart failure is underdiagnosed in this population, the recommendation will be challenging to implement and has significant workload implications, as heart failure often presents in insidious, nonspecific ways in primary care.

For patients with type 2 diabetes and heart failure with reduced ejection fraction, SGLT2 inhibitors are recommended to reduce the risk for heart failure hospitalization and cardiovascular death. Again, this recommendation is independent of glycemic control. In addition, for patients with type 2 diabetes and heart failure with mid-range ejection fraction or heart failure with preserved ejection fraction (that is, left ventricular ejection fraction > 40%), SGLT2 inhibitors are also recommended to reduce the risk for heart failure hospitalization or cardiovascular death independent of glycemic control. This recommendation is consistent with other updated global heart failure guidance. Increasingly, the pillars of heart failure therapy are being challenged with the early initiation of SGLT2 inhibitors, given their compelling evidence base, early symptomatic benefit, and ease of use, with less requirement of routine blood monitoring.

Finally, for patients with type 2 diabetes and chronic kidney disease, SGLT2 inhibitors and finerenone are now recommended to reduce the risk for kidney failure and cardiovascular disease, independent of glycemic control and in addition to standard of care.

Finerenone is a nonsteroidal selective mineralocorticoid receptor antagonist with quite different pharmacokinetics and clinical effects, compared with those of spironolactone and eplerenone, which are steroidal MRAs. Specifically, finerenone does not significantly lower blood pressure and has fewer steroid-induced adverse effects such as gynecomastia, impotence, and low libido. However, like steroidal MRAs, finerenone can result in hyperkalemia.

Finerenone has demonstrated significant kidney and cardiovascular benefits across the spectrum of chronic kidney disease in patients with type 2 diabetes. It entails no significant imbalance in adverse events, hence this recommendation. This observation reinforces the importance of measuring urinary albumin–creatinine ratio in patients with type 2 diabetes and preserved kidney function.

In conclusion, the 2023 ESC guidelines for the management of cardiovascular disease in patients with diabetes are forward-thinking recommendations. They look beyond glycemia and reflect the current evidence for newer glucose-lowering therapies with proven cardiorenal benefits. Nevertheless, the implementation of these guidelines will be challenging, given their workload implications, the unstable supply of GLP-1 receptor agonists, and a persisting glucocentric approach to type 2 diabetes care in some areas. Implementation will require ongoing education for health care professionals about the risk-benefit ratios of SGLT2 inhibitors and GLP-1 receptor agonists. It also will require a re-evaluation of workforce strategy to support the development of a skilled and sustainable workforce.

Using SCORE2 Diabetes will be a change in practice for me, as I have been using QRISK3, which is a United Kingdom–based cardiovascular risk tool that has been less extensively validated in patients with type 2 diabetes. Helpfully, an ESC CVD Risk Calculation app is available and can be tailored to your geographical region to calculate a SCORE2-Diabetes risk score easily. For example, Eastern Europe has a higher cardiovascular risk profile than Western Europe.

Cardiovascular risk categories are now defined on the basis of the presence of atherosclerotic cardiovascular disease, severe target-organ damage, or the 10-year cardiovascular risk using SCORE2-Diabetes.

For patients at very high cardiovascular risk (for example, those with type 2 diabetes and established atherosclerotic cardiovascular disease), the ESC guidance recommends dual therapy with a GLP-1 receptor agonist and an SGLT2 inhibitor to reduce cardiovascular risk independent of glucose control (that is, A1c). This dual therapy is recommended in addition to standard-of-care antiplatelet, antihypertensive, and lipid-lowering therapies.

There is no doubt that the evidence for GLP-1 receptor agonist use and reduction in atherosclerotic cardiovascular disease in type 2 diabetes is compelling, perhaps more so than the evidence for SGLT2 inhibitor use. However, this recommendation will be challenging to implement, given the current global supply issues with GLP-1 receptor agonists, which are driven by the off-label use of these medications for the management of obesity. GLP-1 receptor agonist supplies are not expected to stabilize until mid-2024.

Controversially, the updated ESC guidance suggests the use of metformin only in patients with type 2 diabetes and atherosclerotic cardiovascular disease if additional glucose control is required. This is a misstep, in my opinion, as insulin resistance is one of the key pathophysiologic abnormalities in patients with type 2 diabetes. One of the key advantages of metformin is an improvement in insulin sensitivity. This recommendation will not change my practice, and I will continue to prescribe metformin alongside GLP-1 receptor agonists or SGLT2 inhibitors for my patients at highest cardiovascular risk.

The updated ESC guidance also explicitly reminds healthcare professionals to look for significant comorbidities, such as heart failure of all subtypes and chronic kidney disease.

The ESC guidance recommends a systematic survey for heart failure symptoms and signs at each clinical encounter in all patients with type 2 diabetes. Although I agree that heart failure is underdiagnosed in this population, the recommendation will be challenging to implement and has significant workload implications, as heart failure often presents in insidious, nonspecific ways in primary care.

For patients with type 2 diabetes and heart failure with reduced ejection fraction, SGLT2 inhibitors are recommended to reduce the risk for heart failure hospitalization and cardiovascular death. Again, this recommendation is independent of glycemic control. In addition, for patients with type 2 diabetes and heart failure with mid-range ejection fraction or heart failure with preserved ejection fraction (that is, left ventricular ejection fraction > 40%), SGLT2 inhibitors are also recommended to reduce the risk for heart failure hospitalization or cardiovascular death independent of glycemic control. This recommendation is consistent with other updated global heart failure guidance. Increasingly, the pillars of heart failure therapy are being challenged with the early initiation of SGLT2 inhibitors, given their compelling evidence base, early symptomatic benefit, and ease of use, with less requirement of routine blood monitoring.

Finally, for patients with type 2 diabetes and chronic kidney disease, SGLT2 inhibitors and finerenone are now recommended to reduce the risk for kidney failure and cardiovascular disease, independent of glycemic control and in addition to standard of care.

Finerenone is a nonsteroidal selective mineralocorticoid receptor antagonist with quite different pharmacokinetics and clinical effects, compared with those of spironolactone and eplerenone, which are steroidal MRAs. Specifically, finerenone does not significantly lower blood pressure and has fewer steroid-induced adverse effects such as gynecomastia, impotence, and low libido. However, like steroidal MRAs, finerenone can result in hyperkalemia.

Finerenone has demonstrated significant kidney and cardiovascular benefits across the spectrum of chronic kidney disease in patients with type 2 diabetes. It entails no significant imbalance in adverse events, hence this recommendation. This observation reinforces the importance of measuring urinary albumin–creatinine ratio in patients with type 2 diabetes and preserved kidney function.

In conclusion, the 2023 ESC guidelines for the management of cardiovascular disease in patients with diabetes are forward-thinking recommendations. They look beyond glycemia and reflect the current evidence for newer glucose-lowering therapies with proven cardiorenal benefits. Nevertheless, the implementation of these guidelines will be challenging, given their workload implications, the unstable supply of GLP-1 receptor agonists, and a persisting glucocentric approach to type 2 diabetes care in some areas. Implementation will require ongoing education for health care professionals about the risk-benefit ratios of SGLT2 inhibitors and GLP-1 receptor agonists. It also will require a re-evaluation of workforce strategy to support the development of a skilled and sustainable workforce.

TOPLINE:

Compared with body mass index, waist-hip ratio (WHR) had the strongest and most consistent association with all-cause mortality and was the only measurement unaffected by BMI.

METHODOLOGY:

• Cohort study of incident deaths from the U.K. Biobank (2006-2022), including data from 22 centers across the United Kingdom.
• A total of 387,672 participants were divided into a discovery cohort (n = 337,078) and validation cohort (n = 50,594), with the latter consisting of 25,297 deaths and 2,297 controls.
• The discovery cohort was used to derive genetically determined adiposity measures while the validation cohort was used for analyses.
• Exposure-outcome associations were analyzed through observational and mendelian randomization analyses.

TAKEAWAY:

• In adjusted analysis, a J-shaped association was found for both measured BMI and fat mass index (FMI), whereas the association with WHR was linear (hazard ratio 1.41 per standard deviation increase).
• There was a significant association between all three adiposity measures and all-cause mortality, with odds ratio 1.29 per SD change in genetically determined BMI (P = 1.44×10-13), 1.45 per SD change in genetically determined FMI, 1.45 (P = 6.27×10-30), and 1.51 per SD change in genetically determined WHR (P = 2.11×10-9).
• Compared with BMI, WHR had the stronger association with all-cause mortality, although it was not significantly stronger than FMI.
• The association of genetically determined BMI and FMI with all-cause mortality varied across quantiles of observed BMI, but WHR did not (P = .04, P = .02, and P = .58, for BMI, FMI, and WHR, respectively).

IN PRACTICE:

“Current World Health Organization recommendations for optimal BMI range are inaccurate across individuals with various body compositions and therefore suboptimal for clinical guidelines.”
