Clinical Trial Summary

This is a Phase 3 study to evaluate the efficacy, safety, and tolerability of crinecerfont versus placebo administered for 28 weeks in approximately 81 pediatric participants with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. The study consists of a 28-week double blind, placebo-controlled period, followed by 24 weeks of open-label treatment with crinecerfont. Subsequently, participants may elect to participate in the open-label extension (OLE) period. The duration of participation in the study is approximately 14 months for the core study and will be a variable amount of time per participant for the OLE (estimated to be approximately 3 years).
