Global Safety and Efficacy Registration Study of Crinecerfont in Pediatric Participants With Classic Congenital Adrenal Hyperplasia (CAHtalyst Pediatric Study)
NCT04806451 · View on ClinicalTrials.gov ↗
Study 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).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04806451
The ClinicalTrials.gov registry entry for NCT04806451 describes a study currently listed as active not recruiting. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 103 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Neurocrine Biosciences, which has 47 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Congenital Adrenal Hyperplasia appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04806451 reports 20 study locations spanning 14 distinct geographic areas — top geographies include California, New York, Oklahoma. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
