Open label extension data from investigational compound paltusotine orally presented at the 35th Brazilian Congress of Endocrinology and Metabolism Lowered and maintained IGF-1 at levels comparable to prior injected somatostatin receptor ligands (SRL) Generally well-tolerated with a safety profile similar to that of injected SRLs Nearly 90% of participants preferred once daily oral paltusotine to injected SRLs SAN DIEGO, Sept. 06, 2022 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals (Nasdaq: CRNX) today announced that Monica R. Gadelha, MD, PhD, 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 new data from the planned two-year interim analysis of the ACROBAT Advance open label extension (OLE) study at the 35th Brazilian Congress of Endocrinology and Metabolism (CBEM). These results show that paltusotine, an investigational compound, lowered and maintained insulin-like growth factor-1 (IGF-1) at levels comparable to prior injected SRL therapy for up to 103 weeks in participants living with acromegaly. This was seen in all subsets of participants representing a range of baseline disease control. Paltusotine was well tolerated with a safety profile similar to that of injected SRLs, including when used in combination with adjunctive therapy Following the conclusion of the Evolve and Edge studies, 88% (n=43) of the eligible participants opted to continue into the Advance OLE study. In addition, 89% (n=32) of participants who had completed 52 weeks of treatment or had discontinued treatment selected once-daily oral paltusotine as their preferred treatment option over injected SRLs. “Paltusotine’s ability to maintain IGF-1 levels on a long-term basis with a favorable safety profile in a broad range of acromegaly patients is promising,” stated Dr. Gadelha. “This preliminary data, combined with the preference participants had for oral paltusotine over the injected standard-of-care, speaks to the potential paltusotine may have as a long-term therapy for acromegaly.” Dr. Gadelha will present an additional poster of the Advance OLE data at the European Neuroendocrine Association (ENEA) meeting. That presentation, titled “Long-Term Treatment with Oral Paltusotine for Acromegaly: Results from the ACROBAT Advance study” will be made on September 9th. About ACROBAT Advance OLE StudyEnrollment in the Advance OLE study was offered to participants from the Phase 2 ACROBAT Evolve and Edge studies of acromegaly patients who were under a variety of degrees of baseline biochemical control as defined by IGF-1 levels when treated with regimens that included an injected SRL. Paltusotine was well tolerated in the Advance OLE study. Overall, paltusotine’s safety profile has continued to be similar to that of injected SRLs, including when used in combination with adjunctive therapy. About AcromegalyAcromegaly is a serious disease generally caused by a pituitary adenoma, a benign tumor that secretes growth hormone (GH). Excess GH causes excess secretion of IGF-1 from the liver. Together, excess of these hormones leads to the symptoms of acromegaly, including abnormal growth of hands and feet, alteration of facial features, arthritis, carpal tunnel syndrome, joint aches, deepening of voice due to enlarged vocal cords, fatigue, sleep apnea, enlargement of heart, liver and other organs, and changes in glucose and lipid metabolism. Surgical removal of pituitary adenomas, if possible, is the preferred initial treatment for most acromegaly patients. Pharmacological treatments are used for patients who are not candidates for surgery, or when surgery is unsuccessful in achieving treatment goals. Approximately 50% of patients with acromegaly prove to be candidates for pharmacological treatment. Long-acting SRLs are the most common initial pharmacologic treatment; however, these drugs require monthly depot injections with large gauge needles that are commonly associated with pain, injection site reactions, and increased burden of therapy on the lives of patients. About PaltusotinePaltusotine is an investigational, orally available nonpeptide (small molecule) agonist that is highly selective for the somatostatin receptor type 2 (SST2). It was designed by the Crinetics discovery team to provide a once-daily oral option for patients with acromegaly and neuroendocrine tumors. A previously completed Phase 1 trial of paltusotine showed clinical proof of concept by providing evidence of potent suppression of the growth hormone axis in healthy volunteers. In Phase 2 trials, paltusotine maintained IGF-1 levels in acromegaly patients who switched from injectable depot medications to once-daily paltusotine. IGF-1 is the primary biomarker endocrinologists use to manage their acromegaly patients. About Crinetics PharmaceuticalsCrinetics 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, a 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 CRN04777, an investigational, oral somatostatin receptor type 5 (SST5) agonist for congenital hyperinsulinism, and for CRN04894, an investigational, oral ACTH antagonist for the treatment of Cushing’s disease, congenital adrenal hyperplasia, and other diseases of excess ACTH. All of the company’s drug candidates are orally delivered, small molecule new chemical entities resulting from in-house drug discovery efforts.
