Crinetics Pharmaceuticals Doses First Patient in Pivotal Adult Trial of Atumelnant for Congenital Adrenal Hyperplasia
Dec. 11, 2025 - Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) has announced the dosing of the first patient in its CALM-CAH Phase 3 trial. This pivotal study investigates atumelnant, a novel oral ACTH receptor antagonist intended to treat classic congenital adrenal hyperplasia (CAH).
Overview of the CALM-CAH Phase 3 Trial
The CALM-CAH Phase 3 trial aims to evaluate the efficacy of atumelnant in normalizing adrenal androgen levels while concurrently reducing glucocorticoid levels. Dr. Dana Pizzuti, Chief Medical and Development Officer of Crinetics, highlighted the trial's unique endpoints, stating, "CALM-CAH sets a new standard in terms of assessing overall disease control."
This trial follows promising results from earlier Phase 2 studies, where atumelnant demonstrated significant reductions in key biomarkers relevant to CAH. Notable markers included androstenedione and 17-hydroxyprogesterone, alongside improvements in adrenal size and menstrual regularity among participants.
Significance of Atumelnant
Atumelnant is the first and only small molecule ACTH receptor antagonist currently in late-stage clinical development. Its mechanism is designed to inhibit the pathway responsible for excess androgen production in patients with CAH.
Clinical Advancements and Designation
- Recent Orphan Drug Designation by the FDA
- Randomized, placebo-controlled trial format
- Focus on reducing excess androgens and improving treatment outcomes
Background of Crinetics Pharmaceuticals
