Atumelnant (80 mg) Achieved a 67% Mean Reduction in Androstenedione Levels While Simultaneously Enabling 88% of Participants Completing 12 Weeks of Treatment to Successfully Reduce Glucocorticoid Dose to Physiologic Replacement Levels
Atumelnant's Favorable Benefit/Risk Profile Was Maintained in Cohort 4 and Open-Label Extension of Phase 2 CAH Study With No Hepatic Transaminase Adverse Events
Management to Host Investor Conference Call Today at 8:30 AM ET
Jan. 05, 2026 -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today announced PALSONIFY U.S. unaudited and preliminary net product revenue of over $5 million for fourth-quarter 2025. Crinetics also announced positive topline results from the fourth cohort of its Phase 2 congenital adrenal hyperplasia (CAH) study of investigational atumelnant, a novel, once-daily oral adrenocorticotropic hormone (ACTH) receptor antagonist candidate being developed for the treatment of classic CAH and ACTH-dependent Cushing’s syndrome.
"I’m very proud of our team’s strong execution of Palsonify's launch in acromegaly. We are delivering impressive results, highlighted by over 200 enrollment forms in the first three months after FDA approval, a broad prescriber base, and continued momentum toward favorable payer coverage,” said Scott Struthers, Ph.D., founder and chief executive officer of Crinetics. "Further, we are excited to announce additional positive atumelnant clinical data which reinforces its potential to become an uncompromising, highly differentiated treatment for people struggling with CAH. Today’s launch update and clinical results mark two major steps forward for becoming the premier global endocrine company and to advance our unique portfolio that has been purposefully built to redefine the standard of care for people struggling with endocrine and endocrine-related diseases."
Crinetics is highly encouraged by early results from the launch of PALSONIFY, which was approved by the U.S. Food and Drug Administration (FDA) on September 25, 2025 for the first-line treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option. Crinetics recognized over $5 million of revenue from PALSONIFY during the fourth quarter of 2025. Feedback from patients, physicians, and payers has been very positive thus far. Notably, Crinetics’ continued engagement with payers has resulted in early formulary inclusions, reflecting payers’ appreciation of PALSONIFY’s value proposition.

The TouCAHn trial is an open-label, global, Phase 2 study designed to evaluate the efficacy, safety, and pharmacokinetics of atumelnant when administered for 12 weeks in people with CAH caused by 21-hydroxylase deficiency. The fourth cohort of the study enrolled 10 patients with classic CAH on a stable dose of glucocorticoid replacement; two patients withdrew consent. The participants received atumelnant (80 mg) once daily in the morning and underwent glucocorticoid (GC) dose reduction toward physiologic levels (2/day hydrocortisone (HC) or equivalent) in weeks 2 to 10.
Primary endpoints included change from baseline in morning serum androstenedione (A4) levels and incidence of treatment-emergent adverse events.
Treatment with atumelnant resulted in rapid, sustained lowering of androstenedione (in all 8 patients that completed the fourth cohort). Seven out of these 8 patients continued to maintain lower A4 after glucocorticoid doses were reduced to physiologic levels.

Atumelnant was observed to be well-tolerated, with no serious adverse events and no treatment-related severe adverse events. No participants discontinued due to adverse events. No patients experienced hepatic transaminase adverse events.

1 An enrollment form is an official document containing both HCP and patient consent, submitted to CrinetiCARE or specialty pharmacies (Orsini or Biologics) to initiate a patient on Palsonify. Pituitary treatment centers (PTCs) or community practices may also choose to submit an enrollment form to CrinetiCARE when dispensing the medication directly to the patient.

A data snapshot with limited source data verification from the first 7 patients in the Open-Label Extension (OLE) to have completed 13 weeks shows both serum A4 reductions and GC dose reductions that are in line with those seen in Cohort 4.
Additionally, investigators have not observed any serious adverse events or any treatment-related severe adverse events, and have not observed any hepatic transaminase adverse events to date with 25 patients enrolled and with 7 participants who have completed over 20 weeks of treatment in the study.
Atumelnant continues to be well-tolerated with a growing safety database including over 750 weeks of cumulative adult CAH patient exposure. In the overall clinical program, to date, over 200 participants have been exposed to atumelnant in a combination of healthy volunteer, clinical pharmacology, Cushing’s and CAH studies and continues to demonstrate a favorable risk-benefit profile.
Investigational atumelnant is the first in class and only once-daily, oral adrenocorticotropic hormone (ACTH) receptor antagonist that acts selectively at the melanocortin type 2 receptor (MC2R) on the adrenal gland in late-stage clinical development. Diseases associated with excess ACTH can have a significant impact on physical and mental health. Novel atumelnant has exhibited strong binding affinity for MC2R in preclinical models and has demonstrated suppression of adrenally derived glucocorticoids and androgens that are under the control of ACTH. Data from a 12-week Phase 2 study consistently demonstrated compelling treatment benefits of atumelnant, evidenced by the rapid, substantial and sustained statistically significant reductions in key CAH disease related biomarkers, including A4 and 17-hydroxyprogesterone, in a diverse population. Currently in Phase 3 clinical development, atumelnant holds the potential to offer transformational care for individuals living with congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome. This breakthrough could revolutionize the management of these conditions, providing hope for unprecedented improvements in quality of life.
Crinetics Pharmaceuticals is a global pharmaceutical company committed to transforming the treatment of endocrine diseases and endocrine-related tumors through science rooted in patient needs. Crinetics is focused on discovering, developing, and commercializing novel therapies, with a core expertise in targeting G-protein coupled receptors (GPCRs) with small molecules that have specifically tailored pharmacology and properties.
Crinetics’ lead product, PALSONIFY™ (paltusotine), is the first once-daily, oral treatment approved by the U.S. FDA for the treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option. Paltusotine is also in clinical development for carcinoid syndrome associated with neuroendocrine tumors. Crinetics’ deep pipeline of 10+ disclosed programs includes late-stage investigational candidate atumelnant, which is currently in development for congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome, and CRN09682, a nonpeptide drug conjugate candidate that is being developed to treat SST2 expressing neuroendocrine tumors and other SST2 expressing solid tumors. Additional discovery programs address a variety of endocrine conditions such as neuroendocrine tumors, Graves’ disease (including Graves’ hyperthyroidism and Graves’ orbitopathy, or thyroid eye disease), polycystic kidney disease, hyperparathyroidism, diabetes, obesity, and GPCR-targeted oncology indications.
