Crinetics Pharmaceuticals Reports First Quarter 2021 Financial Results and Provides Corporate Update

Paltusotine Phase 3 PATHFNDR program in acromegaly initiated in 2Q 2021

Phase 1 data for CRN04894 and CRN04777 expected in mid-2021

SAN DIEGO, May 06, 2021 (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 financial results for the first quarter ended March 31, 2021 and provided a corporate update.

“In the first quarter we achieved key clinical and regulatory milestones across our pipeline,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. “Based on our interactions with the FDA and other regulators, we developed a robust Phase 3 program for paltusotine that is designed to support its approval for all acromegaly patients who require pharmacotherapy, including both untreated patients and those switching from injected standard of care. This progress was complemented by the advancement of CRN04894 and CRN04777 into Phase 1 trials in healthy volunteers, which are designed to generate safety, pharmacokinetic, and biomarker data that could establish clinical proof of concept and provide important dose guidance information for subsequent trials in patients. Looking ahead, we are on track for a steady cadence of catalysts through the remainder of the year, including data from both of our Phase 1 trials and the initiation of a clinical study in patients with neuroendocrine tumors complicated by carcinoid syndrome.”

First Quarter and Subsequent Highlights

• Announced the design of the Phase 3 program for paltusotine in acromegaly. In March 2021, Crinetics announced plans to initiate two Phase 3 studies based on interactions with the U.S. Food and Drug Administration (FDA) and other regulators. The first of these studies, PATHFNDR-1, is a double-blind, placebo-controlled, nine-month clinical trial evaluating the safety and efficacy of paltusotine in acromegaly patients who are biochemically controlled (IGF-1 ≤ 1.0 × upper limit of normal [ULN]) and who are on stable doses of somatostatin receptor ligand monotherapy (octreotide LAR or lanreotide depot). The second study, PATHFNDR-2, is a double-blind, placebo-controlled, twelve-week trial in acromegaly patients with elevated IGF-1 levels who are medication naïve or who are not being treated with pharmacotherapy (untreated patients). If successful, Crinetics believes these trials could support registration of paltusotine in the United States and Europe for all acromegaly patients who require pharmacotherapy, including untreated patients and those switching from standard of care. The company initiated PATHFNDR-1 in April and expects to initiate PATHFNDR-2 in 2H 2021.

• Showcased broad clinical-stage pipeline at ENDO 2021. In March 2021, Crinetics gave presentations on its three clinical programs at the Endocrine Society’s annual ENDO 2021 congress. Posters on the company’s acromegaly program included a summary of the previously announced ACROBAT Edge Phase 2 results, as well as details of the new tablet formulation of paltusotine. Presentations related to the company’s earlier stage clinical programs included a poster with preclinical data supporting the development of CRN04777 as a treatment for congenital hyperinsulinism (HI) and a live oral presentation with preclinical evidence supporting the further evaluation of CRN04894 in Cushing’s disease and congenital adrenal hyperplasia (CAH).
• Advanced ACTH antagonist CRN04894 into a Phase 1 study designed to provide clinical proof of concept. In February 2021, Crinetics initiated a Phase 1 study of CRN04894, an investigational, oral, nonpeptide adrenocorticotropic hormone (ACTH) antagonist being developed for the treatment of diseases associated with excess ACTH such as Cushing’s disease and congenital adrenal hyperplasia (CAH). This study is designed to evaluate the safety and tolerability of CRN04894 in healthy volunteers, and to provide clinical proof-of-concept data by measuring the effect of CRN04894 on the suppression of endocrine biomarkers that are used as key endpoints in patient studies and reflect the ability of CRN04894 to block ACTH-stimulated adrenal function. This healthy volunteer trial is also expected to provide important information for dose selection and be predictive of efficacy in Cushing’s disease and CAH patients. Crinetics expects preliminary safety, pharmacokinetic, and endocrine biomarker data in mid-2021.
• Advanced SST5 agonist CRN04777 into a Phase 1 study designed to provide clinical proof of concept. In February 2021, Crinetics initiated a Phase 1 study of CRN04777, an investigational, oral, nonpeptide somatostatin receptor type 5 (SST5) agonist. CRN04777 is being developed as a treatment for congenital HI, a rare genetic disease in which excess insulin secretion causes life-threatening hypoglycemia (low blood glucose). This study is designed to evaluate the safety and tolerability of CRN04777 in healthy volunteers and provide clinical proof-of-concept data by measuring both the ability of CRN04777 to inhibit glucose- and sulfonylurea-induced insulin secretion and the corresponding effects on blood glucose levels. These endocrine biomarkers are indicative of the ability of CRN04777 to prevent hypoglycemia and are expected to provide information for dose selection and be predictive of efficacy in patients with hyperinsulinism. Crinetics expects preliminary safety and pharmacological effect data in mid-2021.
• Strengthened balance sheet with successful common stock offering. In April 2021, Crinetics completed an underwritten follow-on offering and raised net proceeds of approximately $72.5 million.
  

First Quarter 2021 Financial Results

• Research and development expenses were $17.6 million for the three months ended March 31, 2021, compared to $13.9 million for the same period in 2020. The increase was primarily attributable to additional personnel costs and clinical development and manufacturing activities for paltusotine, CRN04894, and CRN04777 as well as the company’s other preclinical programs.
• General and administrative expenses were $5.3 million for the three months ended March 31, 2021, compared to $4.0 million for the same period in 2020. The increase was primarily due to additional personnel costs to support the company’s growth.
• Net loss for the three months ended March 31, 2021 was $22.9 million, compared to a net loss of $17.4 million for the three months ended March 31, 2020.
• Unrestricted cash, cash equivalents and investments totaled $150.7 million as of March 31, 2021, compared to $170.9 million as of December 31, 2020. The cash balance at the end of March does not include the $72.5 million of net proceeds from the follow-on offering completed in April.
• As of April 30, 2021, the company had 37,593,371 common shares outstanding.
