Crinetics to Showcase the Next Generation of Endocrinology Innovation at ENDO 2025 with Eight Presentations From its Deep Pipeline
Long-term efficacy and safety data on PALSONIFYTM (paltusotine) in acromegaly to be presented, including evidence of both biochemical and symptom control with a well-tolerated safety profile in patients switching treatments and those not previously pharmacologically treated
Atumelnant Phase 2 trial results in congenital adrenal hyperplasia (CAH) to be featured in oral presentation
Data from early-stage development program in Graves’ hyperthyroidism and orbitopathy also to be featured
SAN DIEGO, June 30, 2025 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today announced eight abstracts from its novel clinical development programs, including oral presentations featuring its lead investigational drug candidate, PALSONIFY™ (paltusotine)* and investigational candidate atumelnant, will be presented at the Endocrine Society’s Annual Meeting, ENDO 2025, July 12-15, 2025, in San Francisco, California.
“ENDO 2025 will be an incredibly meaningful moment for Crinetics in our mission to be the premier endocrine-focused global pharmaceutical company,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. “For our lead investigational candidate PALSONIFY for acromegaly, we are excited to present long-term data that continue to support the durable, consistent response profile it has shown in earlier pivotal trials. Additionally, compelling Phase 2 trial results from atumelnant in CAH and new data from one of our early-stage development programs demonstrate that the Crinetics pipeline can address significant unmet needs.”
Four abstracts will report results from the PALSONIFY development program, including an oral presentation featuring open-label extension data from the registrational Phase 3 PATHFNDR trials. This presentation will highlight long-term efficacy, safety, and symptom control in people with acromegaly who switched from injectable somatostatin receptor ligands (SRLs) to once-daily oral PALSONIFY. In addition, Crinetics will present three poster presentations: one evaluating symptom stability in acromegaly, one analyzing patient-reported outcomes from both PATHFNDR-1 and PATHFNDR-2 and another on PATHFNDR-2 open-label extension data. Together, these abstracts show PALSONIFY continues to be well tolerated, while providing consistent biochemical and symptomatic disease control.
Crinetics will also present three abstracts from its atumelnant clinical development program, including an oral presentation of Phase 2 trial results in congenital adrenal hyperplasia (CAH). Additional presentations focus on reduction of adrenal volume and rapid and sustained reductions in potent 11-oxygenated androgens, a novel biomarker, in Phase 2 trial participants.
Beyond its two lead programs, Crinetics will present new data from its early-stage pipeline, including data from CRN12755 for Graves’ hyperthyroidism and orbitopathy.
Additional presentation details are shown below. All times are PT:
*The U.S. Food and Drug Administration recently conditionally approved PALSONIFY as the trade name for paltusotine, our once-daily, oral investigational candidate for acromegaly.

AboutPALSONIFY™ (Paltusotine)
Crinetics’ lead development candidate, PALSONIFY, is the first investigational once-daily, oral, selectively-targeted somatostatin receptor type 2 (SST2) nonpeptide agonist that has completed Phase 3 clinical development for acromegaly and is in Phase 3 clinical development for carcinoid syndrome associated with neuroendocrine tumors. It was designed to be a once-daily oral option for the control of acromegaly and carcinoid syndrome. In Phase 3 studies, once-daily, oral PALSONIFY maintained IGF-1 levels and symptom control in patients with acromegaly who were switched from monthly injectable medications (PATHFNDR-1) and rapidly decreased IGF-1 levels and symptom burden in medically untreated acromegaly patients (PATHFNDR-2). IGF-1 is the primary biomarker endocrinologists use to manage acromegaly patients. Results from a Phase 2 study in carcinoid syndrome demonstrated rapid and sustained reductions in flushing episodes and bowel movement frequency, which are the most common symptoms of carcinoid syndrome, leading to the initiation of a Phase 3 trial for control of carcinoid syndrome in patients with neuroendocrine tumors.
About Atumelnant
Atumelnant, Crinetics’ second investigational compound, is the first once-daily, oral adrenocorticotropic hormone (ACTH) receptor antagonist that acts selectively at the melanocortin type 2 receptor (MC2R) on the adrenal gland. Diseases associated with excess ACTH can have significant impact on physical and mental health. 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 demonstrated compelling treatment benefits of atumelnant, evidenced by the rapid, substantial and sustained statistically significant reductions in key CAH disease related biomarkers, including androstenedione and 17-hydroxyprogesterone, in a diverse population. Atumelnant is in development for congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome, with the Phase 3 CALM-CAH trial and a Phase 1/2b trial in ADCS currently enrolling patients.
About Crinetics Pharmaceuticals
Crinetics Pharmaceuticals is a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for endocrine diseases and endocrine-related tumors. Crinetics’ lead development candidate, PALSONIFY (paltusotine), is the first investigational once-daily, oral, selective somatostatin receptor type 2 (SST2) nonpeptide agonist that is in clinical development for acromegaly and carcinoid syndrome associated with neuroendocrine tumors. Atumelnant is currently in development for congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome. All of the company’s drug candidates are orally delivered, small molecule, new chemical entities resulting from in-house drug discovery efforts, including additional discovery programs addressing a variety of endocrine conditions such as hyperparathyroidism, polycystic kidney disease, Graves’ disease (including thyroid eye disease), diabetes, obesity and GPCR-targeted oncology indications.
