Crinetics Announces FDA Acceptance of New Drug Application for Paltusotine for Adult Patients with Acromegaly
SAN DIEGO, Dec. 09, 2024 (GLOBE NEWSWIRE) -- Crinetics Pharmaceuticals, Inc. (NASDAQ:CRNX) today announced the U.S. Food and Drug Administration (FDA) accepted its New Drug Application (NDA) for investigational candidate paltusotine for the treatment and long-term maintenance therapy of acromegaly in adults. If approved, paltusotine will be the first and only once-daily, oral, selective somatostatin receptor type 2 nonpeptide agonist available for adults living with acromegaly.
"With our patient-centered clinical development of paltusotine, we were guided by an unwavering ambition to deliver a new generation of treatment that provides a once-daily, oral alternative to the currently marketed peptide analog drugs," said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. "We look forward to working with the FDA throughout the review of our new drug application, as we also prepare for a potential commercial launch by building out our infrastructure and engaging with payers and the endocrinology community."
The NDA submission for once-daily, oral paltusotine included data from the PATHFNDR-1 (NCT04837040) and PATHFNDR-2 (NCT05192382) Phase 3 clinical trials, which evaluated paltusotine's safety and efficacy in previously treated and medically untreated adults, respectively. The FDA has set a Prescription Drug User Fee target action date of September 25, 2025, for completing review of the NDA. The FDA also confirmed that an advisory committee meeting is not anticipated as part of the application's review.
Paltusotine was granted Orphan Drug Designation for the treatment of acromegaly by the FDA in July 2020. This designation is provided to drugs defined as being intended for the safe and effective treatment, diagnosis or prevention of rare diseases that affect fewer than 200,000 people in the United States.
ABOUT PALTUSOTINE
Crinetics' lead development candidate, paltusotine, is the first investigational once-daily, oral, selectively-targeted somatostatin receptor type 2 (SST2) nonpeptide agonist that has completed Phase 3 clinical development for acromegaly and is initiating Phase 3 clinical development for carcinoid syndrome associated with neuroendocrine tumors. It was designed to be a once daily oral option for the control of acromegaly and the symptoms related to carcinoid syndrome. In Phase 3 studies, once-daily, oral paltusotine maintained IGF-1 levels and symptom control in patients with acromegaly who were switched from monthly injectable medications (PATHFNDR-1) and rapidly decreased IGF-1 levels and symptom burden in medically untreated acromegaly patients (PATHFNDR-2). IGF-1 is the primary biomarker endocrinologists use to manage acromegaly patients. Results from a Phase 2 study in carcinoid syndrome demonstrated rapid and sustained reductions in flushing episodes and bowel movement frequency, which are the most common symptoms of carcinoid syndrome. Crinetics is preparing to initiate a Phase 3 trial for control of symptoms associated with carcinoid syndrome in patients with neuroendocrine tumors.
ABOUT ACROMEGALY
Acromegaly is a serious rare disease generally caused by a benign pituitary adenoma (tumor) that secretes excess growth hormone (GH). Excess GH secretion causes excess secretion of insulin-like growth factor-1 (IGF-1) from the liver. Prolonged exposure to increased levels of IGF-1 and GH leads to progressive and serious systemic complications, often resulting in bone, joint, cardiovascular, metabolic, cerebrovascular, or respiratory disease. Acromegaly symptoms include headache, joint aches, fatigue, sleep apnea, severe sweating, hyperhidrosis/oily skin, bone and cartilage overgrowth, abnormal growth of hands and feet, enlargement of heart, liver and other organs and alteration of facial features. Uncontrolled acromegaly results in increased mortality and has a debilitating impact on daily functioning and quality of life.
Monthly depot injections of peptide somatostatin receptor ligands are the most common pharmacologic treatment for people suffering with acromegaly. However, these depots typically require many months to achieve the correct dose level. People suffering with acromegaly often experience a return of symptoms towards the end of the monthly injection cycle and many must adjust their injection frequency to more often than monthly1. Further, these depots are difficult to administer and employ large gauge needles that are commonly associated with pain, injection site reactions and an increased burden on the lives of patients.
