Support tool reduces hypoglycemia risk in type 2 diabetes
TOPLINE:
Use of a novel clinical-decision support tool and shared decision-making in elderly patients with type 2 diabetes managed in a primary care practice and at high risk for hypoglycemic episodes led to a 46% decrease in the number of at-risk patients and discontinuation of hypoglycemic agents in 20% in a prospective, 6-month, single-arm study with 94 patients.
METHODOLOGY:
- The HypoPrevent study enrolled 94 people from a Pennsylvania primary care practice who were at least 65 years old with type 2 diabetes and at risk for hypoglycemia because of treatment with insulin or sulfonylureas, and having a hemoglobin A1c of less than 7.0%.
- Clinicians and patients used a newly devised hypoglycemia reduction clinical-decision support tool developed by the Endocrine Society and a health care consulting company to help guide shared decision-making for a goal A1c level, potential changes to treatment, and other steps to reduce the risk of hypoglycemia.
- Primary outcomes during 6-month follow-up were impact of the intervention on A1c, changes in use of insulin or sulfonylureas, change in the number of study patients at risk for hypoglycemia, and impact on the incidence of nonsevere hypoglycemic events (NSHEs) measured with the Treatment-Related Impact Measure–Non-severe Hypoglycemic Events (TRIM-HYPO) survey.
TAKEAWAY:
- Patients averaged 74 years old, 57% were women, 95% were White, 61% had diabetes for more than 10 years, 48% had chronic kidney disease, 51% were on insulin, 47% on a sulfonylurea, and 80 of the 94 enrolled patients completed all three study visits.
- Nineteen patients (20%) reduced their dose of or discontinued insulin or sulfonylurea.
- In patients with both baseline and follow-up A1c measures, A1c rose from 6.29% at baseline to 6.82%.
- Fifty patients set an A1c goal and had a timely follow-up A1c measurement, and in this subgroup the number of patients at risk for hypoglycemia decreased by 46%, a significant change.
- Patients who reported at least one NSHE at baseline had a significant reduction between the baseline survey and follow-up visits in both the total score as well as each of the five scored domains.
IN PRACTICE:
The HypoPrevent study results with positive results,” concluded the researchers in their report.
SOURCE:
The HypoPrevent study was funded and organized by the Endocrine Society in collaboration with a multicenter team of researchers. The report appeared in the Journal of the American Geriatrics Society.
LIMITATIONS:
Lack of a control group makes it impossible to conclusively determine whether the intervention led to the observed increases in A1c levels, nor can the study exclude regression to the mean as the cause for lowered A1c levels.
DISCLOSURES:
The study received funding from Abbott, Lilly, Merck, Novo Nordisk, and Sanofi. Two coauthors had individual disclosures listed in the report; the other six coauthors had no disclosures.

FDA gives semaglutide two drug safety–related label changes
The FDA added a warning to the drug-interaction section of the Ozempiclabel that reiterates a warning that is already in place in other label sections, reinforcing the message that the glucagon-like peptide-1 (GLP-1) receptor agonist Ozempiccan potentially interact with the action of certain other agents to increase a person’s risk for hypoglycemia.
The added text says: “Ozempic stimulates insulin release in the presence of elevated blood glucose concentrations. Patients receiving Ozempic in combination with an insulin secretagogue (for instance, sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.”
This text was already included in both the “Warning and Precautions” and the “Adverse Reactions” sections of the label. The warning also advises, “The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.”
Reports of ileus episodes after approval
The second addition concerns a new adverse reaction that was identified during the postmarketing experience.
The FDA has received more than 8,500 reports of gastrointestinal issues among patients prescribed glucagon-like peptide-1 (GLP-1) receptor agonists. Ileus is mentioned in 33 cases, including two deaths, associated with semaglutide. The FDA stopped short of saying there is a direct link between the drug and intestinal blockages.
“Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure,” the FDA stated in its approval of the label update.
The same warning for the risk of intestinal blockages is already listed on the labels for tirzepatide (Mounjaro, Lilly) and semaglutide injection 2.4 mg (Wegovy, Novo Nordisk).
The label change comes after a Louisiana woman filed a lawsuit in August that claims she was “severely injured” after using Mounjaro and Ozempic. She claimed the drug makers failed to disclose risks of vomiting and diarrhea due to inflammation of the stomach lining, as well as the risk of gastroparesis.
*Correction, 10/3/23: An earlier version of this article misstated the semaglutide formulation that received the updates.

EASD 2023: A deeper dive into type 1 and type 2 diabetes
Noteworthy at the meeting, taking place Oct. 3-6, in Hamburg, Germany, will be final detailed data from the SURMOUNT-4 trial of the “twincretin” tirzepatide (Mounjaro, Lilly) on obesity. The top-line results, announced by the company in July, showed an average 21.1% weight loss at 36 weeks with tirzepatide injections once weekly among adults with overweight or obesity. The drug is approved in the United States and Europe for treating type 2 diabetes, and approval for obesity is expected in the United States later this year.
In addition, a symposium will present a new EASD/American Diabetes Association (ADA) consensus report, Hyperglycaemic Crisis in Adult Patients with Diabetes, scheduled to be simultaneously published in Diabetologia and Diabetes Care on Oct. 6.
Aside from those, much of the EASD meeting content will feature smaller studies on both type 2 and type 1 diabetes, along with award lectures, symposia, debates, and lots of discussion on hot topics in diabetes and clinical challenges including complications. In essence, it will provide a forum for in-depth follow-up to the jam-packed clinical trial–filled agenda at the ADA meeting in June, said EASD Honorary Secretary Tina Vilsbøll, MD, clinical professor and head of clinic at the Steno Diabetes Center, Copenhagen.
“There were so many large trials at ADA that we just took them in without really having a chance to discuss them. ... There’s so much to discuss with all these new treatments, how do we place them in obesity and diabetes? ... All the data that we have from ADA will make good discussions at EASD,” Dr. Vilsbøll said in an interview.
Indeed, said EASD President Chantal Mathieu, MD, PhD, chair of endocrinology at University Hospital Gasthuisberg Leuven, Belgium, “We always come after ADA. That puts us in a position where we can take deeper dives into the data. ... EASD is a calmer meeting where you can really look at the details.”
Type 2 diabetes: Disease modifying in many ways
Dr. Mathieu told this news organization that a unifying theme for much of the EASD meeting’s content is “We are now entering the era of disease-modifying and disease-disrupting therapies” in both diabetes types.
In type 2, this means “getting to the root, which is obesity, so you’ll see a lot of presentations on the incretin system, but you also don’t get type 2 diabetes if you have an iron-clad beta cell. ... So, we also gave a lot of attention to basic translational research that helps us to understand the role of the beta cell in type 2 diabetes.”
In addition to SURMOUNT-4, there will be oral abstract sessions with follow-up data from the SURPASS series of studies of tirzepatide in type 2 diabetes, other abstract sessions, symposia about incretins and obesity, and an oral abstract session on beta cell function in both diabetes types.
Three debates will address controversial questions in the type 2 diabetes arena. In one, speakers will take opposite sides on “Initial combined therapy for type 2 diabetes: Should diabetes follow hypertension?”
In another, speakers will argue over “Is lasting remission of type 2 diabetes feasible in the real-world setting?” That’s an important question, Dr. Vilsbøll said.
“A person might be able to have a remission but go back if they regain the weight. Do we really have remission? How do we define it? Now, suddenly, we have tools to help people go in the right direction. Now we’re in a place where we can actually help our patients with their cravings and their body weight and all that. It’s more fun to discuss when we have the tools.”
A third debate will tackle the question of whether all people with type 2 diabetes and chronic kidney disease should be on [sodium-glucose co-transporter 2] (SGLT2) inhibitors “by default.”
The Minkowski Prize Lecture will address the regulation of energy and glucose metabolism by the dual incretin receptor agonists, while the EASD-Lilly Anniversary Prize Lecture will be about the role of ectopic lipid in insulin resistance and cardiometabolic disease.
Type 1 diabetes: Both disease modifying and disruptive
For type 1 diabetes, “disease-modifying” and “disruptive” approaches on the meeting agenda include new data on immune modulation for people in early stages in order to prevent or delay insulin dependence, islet transplantation including the use of stem cell–derived beta cells, and the latest in technology including automated insulin delivery systems, also known colloquially as the “artificial pancreas.”
Prize lectures about type 1 diabetes will include the Claude Bernard Lecture, on etiologies of autoimmune diabetes, the Albert Renold Lecture, on “disrupted RNA editing as a path to type 1 diabetes,” and the EASD/Novo Nordisk Foundation Diabetes Prize for Excellence Lecture on automated insulin delivery.
Focus on complications: The known and the emerging
The meeting also will focus a great deal on complications of diabetes, including the well-studied cardiovascular disease, neuropathy, nephropathy, retinopathy, and fatty liver disease as well as others that typically receive less attention, such as gastrointestinal problems and cardiomyopathy.
Another debate will address the question “Is it time to reclassify diabetes complications because microvascular and macrovascular classification is no longer sufficient?” And, the Camillo Golgi Lecture will cover “Diabetes Complications: From Classical to Emerging.”
As always, there’s much more on the agenda including pregnancy and diabetes, cystic fibrosis–derived diabetes, mental health in diabetes, COVID-19 and diabetes, hypoglycemia, and hypoglycemia unawareness.
According to Dr. Vilsbøll, “Clinicians should come and enjoy all the great science we have, interact, and be inspired.”
Dr. Vilsbøll has served on scientific advisory panels, been part of speaker bureaus, and served as a consultant to and/or received research support from Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Gilead, GSK, Mundipharma, Novo Nordisk, Sanofi, and Sun Pharmaceuticals. Dr. Mathieu serves or has served on the advisory panel for Novo Nordisk, Sanofi, Merck Sharp and Dohme Ltd., Eli Lilly and Company, Novartis, AstraZeneca, Boehringer Ingelheim, Roche, Medtronic, ActoBio Therapeutics, Pfizer, Imcyse, Insulet, Zealand Pharma, Avotres, Mannkind, Sandoz, and Vertex. She has served on the speakers bureau for Novo Nordisk, Sanofi, Eli Lilly and Company, Boehringer Ingelheim, AstraZeneca, and Novartis. Financial compensation for these activities has been received by KU Leuven.

Weekly insulin with dosing app beneficial in type 2 diabetes
TOPLINE:
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.

Don’t miss type 1 diabetes in adults
Approximately 4 in 10 cases of type 1 diabetes in adults are diagnosed at age 30 years and older, based on data from nearly 1,000 individuals.
New-onset type 1 diabetes in adults is often misdiagnosed as type 2 diabetes, which may lead to inappropriate care, wrote Michael Fang, PhD, of Johns Hopkins University, Baltimore, and colleagues.
Previous research suggests that more than half of type 1 diabetes cases develop in adults, but data on variations in clinical characteristics and age at diagnosis are limited, the researchers said. “Clarifying the burden of adult-onset type 1 diabetes in the general population may help reduce misdiagnosis.”
In a study published in Annals of Internal Medicine, the researchers identified 947 adults aged 18 years and older with newly diagnosed type 1 diabetes, by using data from the National Health Interview Survey between 2016 and 2022. The subjects’ mean age at the time of the survey was 49 years and 48% were women. The racial/ethnic distribution was 73% non-Hispanic White, 10% non-Hispanic Black, 12% Hispanic, 3%, non-Hispanic Asian, and 3% other race/ethnicity.
Overall, 37% of participants were diagnosed with type 1 diabetes after age 30 years, with an overall median age at diagnosis of 24 years.
Type 1 diabetes was diagnosed later in men than in women, at a median age of 27 years vs. 22 years, respectively, and later in racial/ethnic minorities than in non-Hispanic Whites, with a median age of 26-30 years versus 21 years, respectively.
Autoantibody and C-peptide tests are recommended to confirm type 1 diabetes in adults with a suspected diagnosis, but the best method to identify high-risk adults remains unclear, the researchers wrote in their discussion.
“Traditional markers used to differentiate type 1 and type 2 diabetes, such as body mass index, may have limited utility, especially because obesity is now common in the type 1 diabetes population,” they said. New tools combining clinical features and biomarkers may improve accuracy of diagnosis of type 1 diabetes in the adult population, but more research is needed.
The findings were limited by several factors including misclassification based on self-reports of diagnosis and age, the researchers noted. Other limitations included lack of data on diagnostic measures such as levels of autoantibodies, C-peptides, and other indicators of diabetes, as well as inexact subgroup estimates because of small sample sizes.
“We extended existing research by characterizing the age at diagnosis in a nationally representative sample and by documenting variation across race/ethnicity and clinical characteristics,” they said.
The study was supported by grants from the National Heart, Lung, and Blood Institute. The lead authors had no financial conflicts to disclose. Corresponding author Elizabeth Selvin, PhD, disclosed grants from NIH and FNIH, personal fees from Novo Nordisk, other financial relationships with Wolters Kluwer, and nonfinancial support from many pharmaceutical companies outside the current study; she also serves as deputy editor of Diabetes Care and a member of the editorial board of Diabetologia.

Are vitamin D levels key to canagliflozin’s fracture risk?
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.
The new findings, from a small study of Amish adults with vitamin D deficiency (≤ 20 ng/mL) but without diabetes or osteoporosis, suggest that physicians consider screening for vitamin D deficiency prior to prescribing SGLT2 inhibitor. Alternatively, these patients can simply be prescribed safe, inexpensive, OTC vitamin D supplements without being screening, Zhinous Shahidzadeh Yazdi, MD, of the division of endocrinology, diabetes, and nutrition at the University of Maryland, Baltimore, and colleagues wrote.
“Something as simple as OTC vitamin D might protect against bone fractures caused by chronic multiyear treatment with a drug,” study lead author Simeon I. Taylor, MD, PhD, professor of medicine at the University of Maryland, said in an interview.
In the study, published in the Journal of Clinical Endocrinology and Metabolism, 11 adults with vitamin D deficiency underwent two canagliflozin challenge protocols of 300 mg/d for 5 days, once before and once after vitamin D3 supplementation (either 50,000 IU per week or twice weekly for body mass index < 30 kg/m2 or ≥ 30 kg/m2, respectively), to achieve 25(OH)D of at least 30 ng/mL.
When the participants were vitamin D deficient, canagliflozin significantly decreased 1,25(OH)2D levels by 31.3%, from 43.8 pg/mL on day 1 to 29.1 pg/mL on day 3 (P = .0003). In contrast, after receiving the vitamin D3 supplements, canagliflozin reduced mean 1,25(OH)2D levels by a nonsignificant 9.3%, from 45 pg/mL on day 1 to 41 pg/mL on day 3 (P = .3).
“Thus, [vitamin D3] supplementation provided statistically significant protection from the adverse effect of canagliflozin to decrease mean plasma levels of 1,25(OH)2D (P = .04),” Yazdi and colleagues wrote.
Similarly, when the participants were vitamin D deficient, canagliflozin was associated with a significant 36.2% increase in mean parathyroid hormone (PTH) levels, from 47.5 pg/mL on day 1 to 58.5 pg/mL on day 6 (P = .0009). In contrast, after vitamin D3 supplementation, the increase in PTH was far less, from 48.4 pg/mL on day 1 to 53.3 pg/mL on day 6 (P = .02).
Therefore, the supplementation “significantly decreased the magnitude of the canagliflozin-induced increase in mean levels of PTH (P = .005),” they wrote.
Also, in the vitamin D deficient state, canagliflozin significantly increased mean serum phosphorous on day 3 in comparison with day 1 (P = .007), while after supplementation, that change was also insignificant (P = .8).
“We are saying that SGLT2 inhibitors, when superimposed on vitamin D deficiency, is bad for bone health. This group of people have two important risk factors – vitamin D deficiency and SGLT2 inhibitors – and are distinct from the general population of people who are not vitamin D deficient,” Dr. Taylor noted.
The findings “raise interesting questions about how to proceed,” he said in an interview, since “the gold standard study – in this case, a fracture prevention study – will never be done because it would cost more than $100 million. Vitamin D costs only $10-$20 per year, and at appropriate doses, is extremely safe. At worst, vitamin D supplements are unnecessary. At best, vitamin D supplements can protect some patients against a serious drug toxicity, bone fracture.”
The study was funded by the National Institutes of Health. Dr. Taylor serves as a consultant for Ionis Pharmaceuticals and receives an inventor’s share of royalties from the National Institute of Diabetes, Digestive, and Kidney Diseases for metreleptin as a treatment for generalized lipodystrophy. Dr. Yazdi disclosed no relevant financial relationships.

Tirzepatide superior to semaglutide for A1c control, weight loss
, 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.

, 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).

Echocardiography boosts prognostic power in T1D
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.
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.

FDA panel rejects implanted GLP1-RA dosing device for T2D
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.

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.
