The DREAMS-3 trial is a randomized, open-label Phase 3 study designed to compare the efficacy and safety of mazdutide (a glucagon receptor/GLP-1 receptor co-agonist) versus semaglutide (a GLP-1 receptor agonist) in Chinese adults with type 2 diabetes (T2D) and obesity. This publication reports the trial's rationale, design, and baseline characteristics rather than outcome results, as the study is ongoing with an expected completion date in early 2026. A total of 349 participants (mean age 42.4 years; 44.7% male) were randomized 1:1 to either treatment arm for a 32-week active-controlled period followed by a 24-week extension. At baseline, participants had a mean HbA1c of 8.0%, body weight of 90.5 kg, and BMI of 33.0 kg/m². The mean T2D duration was 1.8 years, and approximately 39.5% were on metformin. The primary endpoint is the proportion of participants achieving HbA1c targets. Notably, comorbidities such as metabolic-associated fatty liver disease and gout/hyperuricemia showed strong associations with BMI. As a design and baseline data paper, no efficacy or safety outcomes are yet available, limiting current evidence value.

Registered Phase 1 interventional trial (recruiting). The purpose of this study is to investigate how the duration of fasting and temporary stopping of Glucagon-Like-Peptide 1 (GLP-1) medications affect the amount of food left in the stomach in people using liraglutide (injected), semaglutide (taken by mouth) or semaglutide (injected). The length of participants participation in the study will depend on the type of GLP-1 RA treatment participants are already using.

This paper presents a hypothesis-generating perspective piece examining the potential interaction between amylin-based therapies — including the pramlintide and cagrilintide receptor agonists, and the combination therapy CagriSema — and the renin-angiotensin system (RAS). The authors hypothesize that amylin receptor agonists may activate the RAS, which could potentially counteract the cardiorenal benefits of these obesity and type 2 diabetes treatments. However, they note the paradox that CagriSema demonstrated meaningful blood pressure reductions in phase 3 trials. The authors further hypothesize that concurrent use of RAS inhibitors (ACE inhibitors or angiotensin-receptor blockers) may redirect amylin-induced RAS activation toward the protective "alternative RAS pathway," promoting vasodilatory, anti-inflammatory, and antiproliferative effects via Mas receptors. To test these hypotheses, the authors propose a research agenda encompassing preclinical studies, post-hoc trial analyses stratified by RAS inhibitor use, biomarker studies, and prospective mechanistic human studies. No original experimental data are presented. Key limitations include the entirely speculative nature of the central claims, the absence of direct supporting evidence, and reliance on inference from existing trial-level observations.

Registered Phase 2 interventional trial (recruiting). This study will explore the use of glucagon-like peptide 1 receptor agonist (GLP-1RA) used concurrently with levonorgestrel intrauterine device in patients with poor surgical candidacy for a hysterectomy or patients who are pursuing fertility sparing. GLP-1RA are a class of medications that mimic the natural hormone glucagon-like peptide-1. These medications trigger the pancreas to release insulin which can help lower blood sugar levels and delay gastric emptying. The recent FDA approval of GLP-1RAs has changed the landscape for pharmacothe

Registered observational trial (enrolling by invitation). This observational study will explore how Wegovy® (Semaglutide) is used in everyday situations, how it might affect things like weight, body mass index (BMI) and waist circumference, and what kind of impact it could have on overall quality of life. The overall purpose of this study is to understand how Wegovy impacts weight when used as part of regular medical care. Participants will be treated with Wegovy as prescribed to the participant by their doctor, in accordance with normal clinical practice. The study will last for about two yea

Adolescents living with obesity, their caregivers, healthcare providers, healthcare systems, policymakers, and payors are now wondering what role health behavior and lifestyle treatment (HBLT) has in terms of body mass index (BMI) reduction, improvements in quality of life and cardiometabolic health, and mitigating nutritional concerns when medications are used.

This cross-sectional pilot study examined the direct-to-consumer market for compounded glucagon-like peptide-1 (GLP-1) receptor agonists in Colorado. Researchers conducted Google searches of business websites advertising compounded GLP-1 products for weight loss across census-defined statistical areas between March and April 2024. They identified 93 websites corresponding to 188 physical locations. Most businesses were categorized as medical/health spas or weight loss services. Semaglutide was the most commonly advertised product (92/93 sites), followed by tirzepatide (40/93). Some sites advertised combination formulations including B vitamins, BPC-157 (flagged by the FDA as unsafe for compounding), and other additives. Seven sites advertised oral formulations. Notably, 41 of 93 websites referenced FDA approval in their product descriptions—a potentially misleading claim, as compounded products are not FDA-approved—and 5 sites incorrectly referred to products as "generic." The study's limitations include its focus on a single state, reliance on publicly available website data, and its pilot/cross-sectional design, which limits generalizability. The authors conclude that regulatory action is needed to address misleading advertising and safety concerns in this market.

Registered Phase 3 interventional trial (active not recruiting). This study will look at how much CagriSema lowers blood sugar and body weight in people with type 2 diabetes. CagriSema is a new investigational medicine. Doctors cannot yet prescribe CagriSema. CagriSema will be compared to a medicine called tirzepatide. Doctors can prescribe tirzepatide in some countries. Participants will either receive CagriSema or tirzepatide. Which treatment the participant will receive is decided by chance. For each participant, the study will last for up to 1 year and 4 months.
