Paltusotine’s Phase 3 PATHFNDR-1 trial in acromegaly fully enrolled and on track for topline data in Q3 2023

Paltusotine lowered and maintained IGF-1 at levels comparable to prior injected SRL therapy for up to 103 weeks in participants living with acromegaly participating in the ACROBAT Advance Long-term Extension Study

SAN DIEGO, Nov. 14, 2022 (GLOBE NEWSWIRE) --  Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX) today reported financial results for the third quarter ended September 30, 2022.

“This has been yet another successful quarter of executing our strategy to build a leading endocrinology company by advancing our clinical pipeline of internally discovered drug candidates and preparing to add to that pipeline with our highly productive drug discovery efforts. Progress includes completion of enrollment in the Phase 3 PATHFNDR-1 trial and reporting Phase 2 open-label extension data demonstrating maintenance of IGF-1 as well as a strong preference among acromegaly patients for oral paltusotine over the injected standard-of-care,” said Scott Struthers, Ph.D., founder and chief executive officer of Crinetics. “We remain on track for two Phase 3 readouts in acromegaly next year. Beyond acromegaly, we maintained strong momentum with our efforts to demonstrate paltusotine’s utility in carcinoid syndrome with a Phase 2 readout expected next year. We also continue to advance CRN04777 and CRN04894 toward patient trials based on the positive proof-of-pharmacology data we reported earlier this year.”

Third Quarter 2022 and Recent Highlights

• Completed enrollment in Phase 3 PATHFNDR-1 study. PATHFNDR-1 is one of two ongoing, placebo-controlled Phase 3 clinical trials evaluating the safety and efficacy of paltusotine in acromegaly patients. Topline data from PATHFNDR-1 are expected in the third quarter of 2023 and topline data from paltusotine’s second Phase 3 trial, PATHFNDR-2, are expected in the fourth quarter of 2023. If successful, Crinetics plans to submit data from the PATHFNDR trials to regulatory authorities in support of applications seeking approval for the broad use of paltusotine for all acromegaly patients who require pharmacotherapy, including untreated patients and those switching from other therapies.
• Reported new long-term safety and efficacy data from ACROBAT Advance open-label extension trial of paltusotine in acromegaly. Results showed that once-daily oral paltusotine lowered and maintained IGF-1 at levels comparable to prior injected somatostatin receptor ligand (SRL) therapy for up to 103 weeks. In addition, paltusotine was well tolerated in the study and 89% of study participants surveyed selected paltusotine as their preferred treatment option over injected SRLs.
• Received a UK Medicines and Healthcare products Regulatory Agency (MHRA) Innovation Passport for CRN04777 for the treatment of congenital hyperinsulinism. The Innovation Passport enables Crinetics to access the Innovative Licensing and Access Pathway (ILAP). The ILAP aims to reduce the time to market for designated medicines by enabling enhanced coordination between sponsors and MHRA leading up to Marketing Authorization Application (MAA) submissions and by providing the opportunity for accelerated MAA reviews.
• Reviewed analyses from preclinical and Phase 1 clinical studies of CRN04894 in an oral presentation at the 10^th International Congress of Neuroendocrinology. CRN04894 is an adrenocorticotropic hormone (ACTH) antagonist being developed as a treatment for Cushing’s disease, congenital adrenal hyperplasia (CAH) and other conditions of ACTH excess. The presentation was delivered by the Crinetics’ vice president of clinical endocrinology, Dr. Peter J. Trainer, and featured the results of a Phase 1 healthy volunteer study demonstrating pharmacologic proof-of-concept for CRN04894. These results showed dose-dependent increases in CRN04894 plasma concentrations as well as reductions of both basal cortisol and elevated cortisol following an ACTH challenge.
• Strengthened leadership team with appointment of Dana Pizzuti, M.D. as chief development officer. Dr. Pizzuti is a board-certified physician with more than 30 years of pharmaceutical industry experience in clinical development, pharmacovigilance, medical and regulatory affairs.
  

Third Quarter 2022 Financial Results

• Research and development expenses were $32.0 million for the three months ended September 30, 2022, compared to $21.6 million for the same period in 2021. The increase was primarily attributable to an increase in spending on manufacturing and development activities of $5.2 million associated with our clinical and nonclinical activities for paltusotine, CRN04777, CRN04894 and our other clinical and preclinical programs and an increase in personnel costs of $4.2 million.
• General and administrative expenses were $11.9 million for the three months ended September 30, 2022, compared to $6.2 million for the same period in 2021. The increase was primarily attributable to an increase in personnel costs of $3.0 million.
• Net loss for the three months ended September 30, 2022, was $41.9 million, compared to a net loss of $27.9 million for the same period in 2021.
• Revenues were $0.5 million for the three months ended September 30, 2022, consisting of license revenue recognized from the license agreement entered into with Sanwa Kagaku Kenkyusho Co., Ltd. in February 2022.
• Unrestricted cash, cash equivalents and investments totaled $368.4 million as of September 30, 2022, compared to $333.7 million as of December 31, 2021.
