Crinetics Pharmaceuticals, Inc.

Business Overview We are a pharmaceutical company committed to transforming the treatment of endocrine diseases and endocrine-related tumors through science rooted in patient needs. We are focused on discovering, developing, and commercializing novel therapies, with a core expertise in targeting GPCRs with small molecules that have specifically tailored pharmacology and properties. Our lead product, PALSONIFY (paltusotine), is the first once-daily, oral treatment approved by the 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 CS associated with NETs. Our deep pipeline of 10+ disclosed programs includes late-stage investigational candidate atumelnant, which is currently in development for CAH and ADCS, and CRN09682, a NDC candidate that is being developed to treat SST2 expressing NETs and other SST2 expressing solid tumors. Additional discovery programs address a variety of endocrine conditions such as NETs, Graves’ disease (including Graves’ hyperthyroidism and Graves’ orbitopathy, or TED), polycystic kidney disease, hyperparathyroidism, diabetes, obesity, and GPCR-targeted oncology indications. Approved Product On September 25, 2025, the FDA approved PALSONIFY as the first and only once-daily oral somatostatin receptor ligand for the treatment of adults with acromegaly who had an inadequate response to surgery and/or for whom surgery is not an option.
