New Data Demonstrating Stable Biochemical and Symptom Levels with Two-Years of Oral Paltusotine Administration Presented at ENDO 2023
Early-Stage Candidates for Primary Hyperparathyroidism and Thyroid Eye Disease Also Featured
Crinetics' Founder & CEO, Scott Struthers Accepted John D. Baxter Prize for Entrepreneurship from ENDO President
SAN DIEGO, June 21, 2023 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) presented efficacy, safety and patient-reported outcome (PRO) data at ENDO 2023 for paltusotine, an experimental, once-daily, oral, small molecule somatostatin receptor type 2 (SST2) agonist in Phase 3 clinical development for the treatment of acromegaly. The Endocrine Society’s annual meeting, ENDO 2023, was held June 15-18, 2023, in Chicago, Illinois.
Dr. Monica R. Gadelha, M.D., Ph.D., professor of endocrinology at the Medical School of the Universidade Federal do Rio de Janeiro and a principal investigator in the Phase 2 ACROBAT program presented results from a planned two-year analysis of the company’s ongoing ACROBAT Advance open-label extension study at a podium presentation at ENDO 2023. Results demonstrated that patients switching from therapy with injected somatostatin receptor ligands (SRLs) to oral paltusotine maintained stable levels of key measures associated with acromegaly including insulin-like growth factor 1, growth hormone, acromegaly symptom diary (ASD) score, blood pressure, hemoglobin A1c, ring size, and body weight.
The ASD score was a composite representing participants’ daily impressions of common acromegaly symptoms including headache, joint pain, sweating, fatigue, weakness, swelling, and numbness/tingling.

“Paltusotine’s ability to maintain stable levels across multiple measures on a long-term basis as compared to baseline values achieved on prior therapy while also displaying a favorable safety profile in a broad range of acromegaly patients is promising and indicates that, if approved, it may represent a potential long-term oral alternative to the injected standard-of-care,” stated Dr. Gadelha.
Crinetics also presented preclinical proof-of-concept data on a parathyroid hormone receptor type 1 (PTH1R) antagonist, which is initially intended for the treatment of primary hyperparathyroidism (PHPT), which leads to hypercalcemia and bone loss if untreated. PHPT affects approximately 100,000 people annually in the U.S. Additional indications that may be addressed by a PTH1R antagonist include humoral hypercalcemia of malignancy (HHM), which is estimated to occur in as many as 200,000 cancer patients annually. The data presented in a poster at ENDO on June 17th show Crinetics’ PTH1R antagonist suppressing PTH-stimulated increases in ionized calcium, urinary cAMP, and bone resorption biomarkers in rats.
In addition, a thyroid-stimulating hormone (TSH) receptor antagonist for the treatment of thyroid eye disease (orbitopathy) associated with Graves’ disease was unveiled in a poster presentation. Graves’ is an autoimmune disease characterized by chronic overstimulation of the TSH receptor, which results in hyperthyroidism. In approximately
“Both PHPT and Graves’ disease are examples of endocrine disorders with well understood endocrinology but in need of better therapeutic options,” added Stephen Betz, Ph.D., Crinetics’ chief scientific officer. “These are exactly the types of endocrine diseases that we aim to address with our oral small molecule drug discovery programs.”
On June 15, 2023, the Endocrine Society’s president, Ursula B. Kaiser, M.D. presented Scott Struthers, Ph.D., Crinetics’ founder and CEO with the Society’s John D. Baxter Prize, an award for recognition of Entrepreneurship in Endocrinology. The Baxter Prize was established in memory of Endocrine Society Past President John D. Baxter, M.D., a world-renowned scientist best known for being the first to clone the human growth hormone gene and starting several biotech companies. During the award session, Dr. Struthers presented a lecture titled, “Adventures Discovering Nonpeptide Oral Drugs Acting at Peptide Hormone Receptors,” highlighting the complex and difficult process of discovering small molecules that target peptide hormone receptors. In addition, he reviewed the history of building Crinetics from bootstrapping with NIH-SBIR grants to the publicly traded company it is today with more than 250 full time staff and operations around the globe.
“At Crinetics, our discovery scientists strive to optimize every atom in each drug candidate to craft the best possible medicine we can for patients with endocrine diseases,” said Dr. Struthers. “These efforts yielded paltusotine, which entered into its first clinical studies in 2017. Since then, the Crinetics team has developed a rich pipeline of additional small molecule drug candidates hoping to improve treatment options for patients with endocrine disorders. I am grateful that the Baxter family and the Endocrine Society has established this prize to bring attention to the role that entrepreneurship can play in bringing all members of our community together to improve patient care and am honored and humbled to have been this year’s recipient.”

About Crinetics Pharmaceuticals
Crinetics Pharmaceuticals is a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors. Paltusotine, an investigational, oral somatostatin receptor type 2 (SST2) agonist, is in Phase 3 clinical development for acromegaly and Phase 2 clinical development for carcinoid syndrome associated with neuroendocrine tumors. Crinetics has demonstrated pharmacologic proof-of-concept in Phase 1 clinical studies for CRN04894, an investigational, oral ACTH antagonist in development for the treatment of Cushing’s disease and congenital adrenal hyperplasia and for CRN04777, an investigational, oral somatostatin receptor type 5 (SST5) agonist in development for congenital hyperinsulinism. All of the company’s drug candidates are orally delivered, small molecule new chemical entities resulting from in-house drug discovery efforts.
