Crinetics Pharmaceuticals (Nasdaq: CRNX) presented on June 14 full results from its 12-week Phase 2 trial of atumelnant (CRN04894) in adults with classic congenital adrenal hyperplasia (CAH), the company's investigational once-daily oral ACTH receptor antagonist. The data showed rapid, substantial, and sustained statistically significant reductions in CAH disease biomarkers including androstenedione and 17-hydroxyprogesterone, with patients able to reduce glucocorticoid doses while maintaining androgen control. A separate Phase 1b/2a interim analysis in ACTH-dependent Cushing's syndrome showed that atumelnant rapidly lowered early-morning cortisol and normalized urinary free cortisol even at lower doses. Both programs are advancing toward Phase 3.
Crinetics also disclosed in the May 7 Q1 update that the company is on track to initiate a seamless Phase 2/3 trial of atumelnant in ACTH-dependent Cushing's syndrome in Q2 2026. The trial will assess efficacy in a broad population including Cushing's disease and ectopic ACTH syndrome. Atumelnant is also in Phase 3 for congenital adrenal hyperplasia. Separately, Crinetics announced an exclusive license agreement with Ohio University to develop an early-preclinical growth hormone receptor antagonist (GHRA) for acromegaly — a mechanism complementary to paltusotine's SST2 agonism that would compete in the same indication once both reach market.
Crinetics Pharmaceuticals reported Q1 2026 results May 7 — total revenue $10.7M (vs $8.5M consensus, +25.7% beat), Palsonify (paltusotine) net product revenue $10.3M in its first full commercial quarter (up from $5.4M in Q4 2025), 263 unique prescribers (up from 125 at year-end), 232 new patient enrollment forms in the quarter, and approximately 70% of patients reimbursed with payer coverage above 60% (target above 75% by Q3). Cash, equivalents, and investments closed at $1.3B. R&D rose 17.6% to $100.1M to fund Phase 3 paltusotine in carcinoid syndrome plus atumelnant Phase 3 programs in congenital adrenal hyperplasia and Cushing's syndrome. Shares rose 4.3% in after-hours trading.
