FDA Approved
GLP-1/GIP Dual Agonist
Overview

A GLP-1/glucagon dual receptor agonist developed by Altimmune, similar in mechanism to survodutide. In Phase 2 trials (MOMENTUM), pemvidutide demonstrated up to 15.6% weight loss at 48 weeks with notable preservation of lean body mass — a differentiating feature compared to other weight loss drugs where significant muscle loss is a concern.

A dual GIP and GLP-1 receptor agonist developed by Eli Lilly. Represents the next generation of incretin-based therapies with potentially superior efficacy to semaglutide for weight loss.

Mechanism of Action

Activates both GLP-1 and glucagon receptors. GLP-1 reduces appetite and food intake. Glucagon activation increases energy expenditure, promotes fat oxidation, and may help preserve lean mass during weight loss by shifting energy substrate utilization toward fat rather than protein catabolism.

Activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors, producing enhanced insulin secretion, appetite suppression, and metabolic improvements beyond what single-agonist drugs achieve.

Common Uses
  • Weight management (investigational)
  • MASH/NASH treatment (investigational)
  • Lean mass preservation during weight loss
  • Weight management
  • Type 2 diabetes treatment
  • Metabolic health improvement
Known Risks
  • GI side effects (nausea, diarrhea)
  • Still in clinical trials — full safety profile not established
  • Potential blood sugar effects
  • Injection site reactions
  • GI side effects (nausea, diarrhea, vomiting)
  • Pancreatitis risk
  • Injection site reactions
  • Potential thyroid concerns
Regulatory Status
Investigational

Phase 2 completed (MOMENTUM trial). Phase 2b for MASH (IMPACT trial) ongoing. Altimmune reported 15.6% weight loss at 48 weeks with lean mass preservation. Phase 3 planning underway. The lean mass preservation claim is a key differentiator if confirmed in larger trials.

FDA Approved

FDA-approved as Mounjaro (diabetes, 2022) and Zepbound (weight management, 2023).
