Summary

This early-stage study tests a new drug called CMP-CPS-001 in healthy adults and women who carry a gene for OTC deficiency, a rare liver condition that can cause dangerous ammonia buildup. The main goal is to check the drug's safety and how the body processes it. Participants receive either the drug or a placebo as a shot under the skin.
