NCT ID NCT07541209

First seen May 06, 2026 · Last updated May 06, 2026

Summary

This study tests a new drug called PTH-IA for Jansen's Metaphyseal Chondrodysplasia (JMC), a very rare genetic bone disease that causes short stature, fractures, and kidney problems. The trial will include up to 12 adults and children to see if the drug is safe and can help control symptoms. Since JMC has no approved treatments, this is a first step toward a potential therapy.
