NCT ID NCT07496463

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests the drug setmelanotide in one person with pseudohypoparathyroidism type 1a (PHP1a), a rare genetic disorder that often causes severe obesity. The participant will receive daily injections of setmelanotide for six months to see if it leads to weight loss and improves metabolic health. The study is very early and small, so results will be preliminary.
