NCT04806451

Brief 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).

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Serum Androstenedione at Week 4

    Blood serum samples were collected for the analysis of serum androstenedione concentrations. Least square (LS) mean and standard error (SE) were calculated using analysis of covariance (ANCOVA) model.

    Baseline, Week 4

Secondary Outcomes (6)

  • Change From Baseline in Serum 17-hydroxyprogesterone (17-OHP) at Week 4

    Baseline, Week 4

  • Percent Change From Baseline in Glucocorticoid Daily Dose at Week 28

    Baseline, Week 28

  • Number of Participants Who Achieved a Reduction to Physiologic Glucocorticoid Dose While Maintaining Androstenedione Control at Week 28

    Week 28

  • Change From Baseline in Body Mass Index (BMI) Standard Deviation Score (SDS) at Week 28

    Baseline, Week 28

  • Change From Baseline in Mean 24-hour Salivary 17-OHP at Week 28

    Baseline, Week 28

  • +1 more secondary outcomes
