SAN DIEGO, July 08, 2020 (GLOBE NEWSWIRE) — Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX), a clinical stage pharmaceutical company focused on the discovery, development and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors, today announced that the U.S. Food and Drug Administration (FDA) has granted paltusotine Orphan Drug Designation for the treatment of acromegaly.
The FDA’s Orphan Drug Designation program provides orphan status to drugs defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases that affect fewer than 200,000 people in the United States. Orphan Drug Designation qualifies the sponsor of the drug for certain development incentives, that may include exemption from FDA prescription drug user fees, financial incentives for qualified clinical development, and seven years of market exclusivity in the U.S. if the treatment is approved.“The orphan drug designation by the FDA for paltusotine to treat acromegaly validates the encouraging clinical data we have seen so far in the Phase 2 ACROBAT Edge clinical trial, and underscores the need for a once daily oral treatment option for patients suffering from this rare disease,” said Michael Monahan, Senior Director of Regulatory Affairs at Crinetics.“Receiving orphan drug designation is another important milestone for the paltusotine program. We look forward to announcing topline results for our ACROBAT clinical program in the fourth quarter of this year and to the initiation of our planned Phase 3 trial for paltusotine in the first half of 2021,” said Ajay Madan, Ph.D., Chief Development Officer of Crinetics.About PaltusotinePaltusotine (formerly CRN00808) is an orally available nonpeptide biased agonist that is designed to be highly selective for the somatostatin type 2 receptor. It was designed by the Crinetics discovery team to provide a once daily oral option for patients with acromegaly and neuroendocrine tumors that are currently treated by injected therapies that sell approximately $3.1 billion annually. Non-clinical chronic toxicology studies are complete and no dose limiting toxicity was identified at the maximum feasible doses in rats and dogs. Crinetics previously completed a Phase 1 trial that showed potent suppression of the growth hormone (GH) axis in healthy volunteers, which provided clinical proof-of-concept. In addition, the molecule’s observed plasma half-life of approximately 2 days suggested the potential for paltusotine for once daily oral administration. A subsequent Phase 1 trial showed that paltusotine was 70% orally bioavailable. Paltusotine is an investigational drug currently undergoing two Phase 2 clinical trials for the treatment of acromegaly, the ACROBAT Edge and Evolve trials. Paltusotine has been discovered, characterized, and developed by Crinetics and U.S. patents have been issued covering paltusotine to 2037.About AcromegalyAcromegaly is a serious disease generally caused by a benign growth hormone secreting tumor in the pituitary. Excess GH secretion causes excess secretion of insulin-like growth factor-1 (IGF-1) from the liver, which causes bone and cartilage overgrowth, organ enlargement, and changes in glucose and lipid metabolism. The symptoms of acromegaly include abnormal growth of hands and feet and changes in shape of the bone and cartilage that result in alteration of facial features. Overgrowth of bone and cartilage and thickening of tissue leads to arthritis, carpal tunnel syndrome, joint aches, deepening of voice due to enlarged vocal cords, sleep apnea due to obstruction of airways, and enlargement of lips, nose, tongue, heart, liver, and other organs.Surgical removal of pituitary adenomas, if possible, is the preferred initial treatment for most acromegaly patients. Pharmacological treatments are used for patients that 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 somatostatin receptor ligands (SRLs) are usually the initial pharmacologic treatment, however these drugs require monthly injections and are commonly associated with pain, injection site reactions, and increased burden in the lives of patients. Although over 90% of patients have demonstrable responses to SRLs (Annals of Internal Medicine. 1992; 117:711-718) only 20-40% of patients achieve normalization of IGF-1 (J Clin Endocrinol Metab 99: 791–799, 2014). Additional pharmacological treatment options include dopamine agonists or GH receptor antagonists that may be used in combination with SRLs.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. The company’s lead product candidate, paltusotine (formerly CRN00808), is an oral, selective nonpeptide somatostatin receptor type 2 biased agonist undergoing two Phase 2 clinical trials for the treatment of acromegaly, an orphan disease affecting more than 25,000 people in the United States. Crinetics plans to advance paltusotine into a Phase 3 trial in acromegaly and a Phase 2 trial for the treatment of carcinoid syndrome associated with neuroendocrine tumors in 2021. The company is also developing an oral nonpeptide somatostatin type 5 agonist for hyperinsulinism, as well as an oral nonpeptide 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 new chemical entities resulting from in-house drug discovery efforts and are wholly owned by the company.
