- Placebo-adjusted reductions in body weight of up to a mean of 8.3% with dapiglutide after 13 weekly doses
- Dapiglutide treatment with doses up to 13 mg was assessed to be safe and well-tolerated with gastrointestinal adverse events consistent with the profile reported with other incretin-based therapies
- Higher doses up to 26 mg over a 28-week treatment period are being evaluated in the ongoing Part 2 of the trial with topline results expected in the first half of 2025
COPENHAGEN, Denmark I September 09, 2024 I Zealand Pharma A/S (“Zealand”) (Nasdaq: ZEAL), (CVR-no. 20 04 50 78), a biotechnology company focused on the discovery and development of innovative peptide-based medicines, today announces positive topline clinical results from a Phase 1b multiple ascending dose (MAD) trial, investigating safety, tolerability, and clinical effects of 13 weeks of dosing with dapiglutide, a long-acting GLP-1/GLP-2 receptor dual agonist in development for weight management1.
“We are both excited and very encouraged by these data from this short-term trial showing substantial and clinically relevant reductions in body weight. Preliminary data further support that dapiglutide possesses a differentiated profile based on its unique dual agonist effects which we expect to translate to a positive effect on inflammation,” said David Kendall, MD, Chief Medical Officer of Zealand Pharma. “We are now evaluating the potential use of higher doses of dapiglutide up to 26 mg over a longer treatment duration of 28 weeks in Part 2 of this ongoing trial and anticipate topline results in the first half of 2025. Importantly, today’s exciting data give us the confidence needed to rapidly progress dapiglutide into a comprehensive Phase 2b trial in people living with overweight and obesity planned for initiation in the first half of 2025.”
In Part 1 of the Phase 1b trial, a total of 54 participants (~85% male) with a median age of 46 years and a median baseline BMI of 30.0 kg/m2 were randomized to receive 13 weekly doses of either dapiglutide or placebo (14:4) within three dose cohorts. At week 13, the estimated mean body weight had decreased by up to 8.3% on a placebo-corrected basis among participants on dapiglutide treatment (up to 6.2% mean weight loss on dapiglutide; 2.1% mean weight gain on placebo)2. No lifestyle modifications, such as diet or exercise, were included in the trial.
Dapiglutide was assessed to be safe and well-tolerated in Part 1 of the trial, with no severe treatment-emergent adverse events (TEAEs) and one serious AE, which was deemed not related to the drug. The most common TEAEs were gastrointestinal (GI), including nausea and vomiting. Only two participants discontinued treatment due to AEs, which were related to the GI system (moderate vomiting). Overall, the number of GI events observed were consistent with clinical trials of other incretin-based therapies with a similar, rapid dose escalation scheme. A low number of participants reported injection site reactions, all of which were mild. Anti-drug antibodies were observed in 14.3% of participants.
Part 2 of this Phase 1b trial is evaluating higher doses of dapiglutide up to 26 mg over a 28-week treatment period with up-titration every fourth week. Zealand expects to report topline results from Part 2 in the first half of 2025 and present further details from Part 1 and Part 2 of this Phase 1b trial at a future scientific congress. The company plans to progress the clinical development of dapiglutide into a Phase 2b trial in people living with overweight and obesity, with initiation expected in the first half of 2025. Also, the company expects to evaluate the potential of dapiglutide in select obesity-related comorbidities.
About the Phase 1b trial
The Phase 1b trial is a single-center, randomized, double-blind, placebo-controlled clinical trial in participants with overweight or obesity (eligible BMI 27.0 to 39.9 kg/m2), investigating safety, tolerability, pharmacokinetics, and pharmacodynamics of multiple doses of dapiglutide as subcutaneous injections using a dose escalation scheme (NCT06000891). The trial consists of Part 1 and Part 2. Part 1 includes 54 participants in three cohorts receiving 13 once-weekly doses of dapiglutide or placebo, with rapid up-titration every second week. Participants randomized to the highest dose cohort (13 mg) received the target dose for a period of 5 weeks. Part 2 of the trial includes 30 participants receiving 28 once-weekly doses of dapiglutide or placebo within one dose cohort, with up-titration every fourth week. Participants will receive the target dose of 26 mg for a period of 4 weeks. No lifestyle modifications, such as diet or exercise, are included in the trial.
About dapiglutide
Dapiglutide is a long-acting, dual GLP-1/GLP-2 receptor agonist for the potential treatment of overweight and obesity. This is a first-in-class peptide designed to leverage the weight loss effects of a potent GLP-1 agonist and address co-morbidities associated with low-grade inflammation through improved intestinal barrier function by GLP-2.
Previous Phase 1 results of dapiglutide in healthy volunteers demonstrated dose-dependent weight loss of up to 4.3% from baseline body weight after four weeks of treatment (NCT04612517). Dapiglutide also delayed gastric emptying and reduced plasma glucose and insulin concentrations in a dose-dependent manner. Pharmacokinetics showed a mean half-life of 123-129 hours across the four dose cohorts, which supports once-weekly dose administration. Multiple weekly doses of dapiglutide were well-tolerated and the safety profile was as expected for GLP-1 and GLP-2 receptor agonists. These results were presented at the ADA 82nd Scientific Sessions in June 2022.
About obesity and low-grade inflammation
Obesity is a chronic disease that results in substantial global morbidity and mortality. Excess fat storage associated with obesity can trigger low-grade systemic inflammation through reduced intestinal barrier integrity, or “leaky gut”. Obesity-related low-grade inflammation may result in several comorbidities, including cardiovascular disease, liver disease, inflammatory bowel disease, and neuro-inflammation.
