Petrelintide
Petrelintide (ZP8396)
Evidence & Status
- Moderate
Overview
Petrelintide (formerly ZP8396) is an investigational long-acting amylin analog studied for weight management. Randomized human studies evaluated once-weekly subcutaneous administration, pharmacokinetics, tolerability and effects on body weight. It remains investigational and is not FDA-approved.
Research Summary
Two randomized, placebo-controlled, double-blind Phase 1 trials evaluated petrelintide. The studies reported an approximately 10-day half-life, body-weight reduction of up to 8.6% after 16 weeks in the studied population, and gastrointestinal disorders as the most common treatment-emergent adverse events, mostly mild. No serious or severe treatment-emergent adverse events were reported, although one participant discontinued because of gastrointestinal adverse events; these early findings do not establish long-term safety or efficacy.
