SAN DIEGO, March 12, 2021 (GLOBE NEWSWIRE) --  Crinetics Pharmaceuticals, Inc. CRNX, a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors, announced upcoming oral and poster presentations at the Endocrine Society's annual ENDO 2021 congress. In addition to a poster summarizing the company's previously announced ACROBAT Phase 2 results of paltusotine for the treatment of acromegaly, Crinetics will provide details of the improved tablet formulation of paltusotine that the company plans to advance into Phase 3 studies.
