Neurocrine Biosciences
Neurocrine Biosciences works on 5 rare diseases tracked on Trial Friend, including Congenital Adrenal Hyperplasia, Friedreich Ataxia, Huntington Disease and 2 more, with 9 recruiting clinical trials and 1 FDA-approved rare disease drug.
Neurocrine Biosciences develops treatments for rare neurological, neuroendocrine, and neuropsychiatric disorders. The company markets INGREZZA (valbenazine) for tardive dyskinesia and Huntington's chorea, CRENESSITY (crinecerfont), approved in December 2024 as the first non-steroidal therapy for classic congenital adrenal hyperplasia, and VYKAT XR (diazoxide choline), the first FDA-approved medicine for hyperphagia in Prader-Willi syndrome, added through the $2.9 billion acquisition of Soleno Therapeutics that closed in May 2026.
Neurocrine Biosciences Drug Pipeline
Neurocrine Biosciences has 9 active clinical trials across 2 development stages, with 9 currently recruiting participants. Clinical trials advance through phases: Phase 1 tests safety in a small group, Phase 2 evaluates effectiveness and side effects, Phase 3 confirms benefit in a larger population, and Phase 4 monitors long-term safety after FDA approval.
Note: This pipeline includes all of Neurocrine Biosciences's active interventional trials, not only those targeting rare diseases. We show the full pipeline because a company's broader research activity, therapeutic expertise, and development infrastructure directly shape its ability to advance rare disease programs. A strong overall pipeline often signals deeper clinical operations, faster enrollment capabilities, and greater commitment to bringing new treatments to patients.
Neurocrine Biosciences Clinical Trials (9)
Active and recruiting clinical trials sponsored by Neurocrine Biosciences, sourced live from ClinicalTrials.gov. Each trial card shows the study phase, current recruitment status, conditions under investigation, study locations, eligibility criteria, and a direct link to the full ClinicalTrials.gov record. You can also download a one-page PDF summary to share with your doctor.
Note: Recruitment statuses on ClinicalTrials.gov may not immediately reflect recent FDA decisions, sponsor announcements, or enrollment changes. Always confirm a trial's current status directly with the study coordinator.
