Crinetics Pharmaceuticals Initiates Phase 1 Study of CRN01941 for the Treatment of Neuroendocrine Tumors

SAN DIEGO, May 21, 2019 (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, today announced the initiation of a Phase 1, double-blind, randomized, placebo-controlled, single- and multiple-dose study to evaluate the safety, pharmacokinetics, and pharmacodynamics of CRN01941 in healthy volunteers. CRN01941 is an oral nonpeptide somatostatin receptor subtype 2 (sst2) biased agonist designed for the treatment of neuroendocrine tumors (NETs) that originate from neuroendocrine cells commonly found in the gut, lung, or pancreas.

“Crinetics is dedicated to building a pipeline of novel therapeutics for rare endocrine diseases and endocrine-related tumors. We are excited to advance CRN01941, our second product candidate, into the clinic,” said Alan Krasner, M.D., Chief Medical Officer of Crinetics. “CRN01941 has the potential to be an orally-administered treatment for patients struggling with NETs. Although these tumors are typically slow growing, they are also often metastatic resulting in significant morbidity and mortality.”

This Phase 1, double-blind, randomized, placebo-controlled, single-dose and multiple-dose study of CRN01941 will enroll up to 119 healthy male and female subjects. This single-center study will be conducted in 3 parts: a single-ascending dose phase (up to 8 cohorts, 8 subjects/cohort), a multiple-ascending dose phase (up to 5 cohorts, 9 subjects/cohort), and single dose phase in elderly subjects (1 cohort, 10 subjects). The primary objectives of the study are to evaluate the safety, tolerability, and pharmacokinetics of single and multiple doses of CRN01941. Additional information about the trial can be found on ClinicalTrials.gov using the identifier NCT03936166.

About Neuroendocrine Tumors

NETs arise from cells of the enteroendocrine system in the gastrointestinal tract (approximately 70% of cases) but can also arise from neuroendocrine cells in the lung (approximately 25% of cases) or, more rarely, the pancreas. In approximately 10-20% of cases, these tumors are associated with excess secretion of serotonin resulting in carcinoid syndrome, which is characterized by severe diarrhea and flushing. Patients with well- and moderately differentiated tumors and distant metastases have a five-year survival probability of ranging from 30-70%. NETs are present in approximately 171,000 adults in the United States and while still an orphan disease, it is the second most common gastrointestinal malignancy after colon cancer.
