Press Release

SAN DIEGO – August 10, 2021 – 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 second quarter ended June 30, 2021 and provided a corporate update.

“We’ve seen advancements across our pipeline over the past months, with the commencement of dosing in the Phase 3 PATHFNDR-1 trial of paltusotine in acromegaly and the announcement of data from CRN04894’s Phase 1 program,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. “This program continues to follow the blueprint of paltusotine’s success, as early clinical data have provided proof-of-concept by demonstrating the dose-dependent and clinically-significant pharmacodynamic effects of CRN04894 on a well validated hormonal biomarker. We are also mirroring this approach with our somatostatin receptor type 5 agonist, CRN04777, and remain on track to report data from the single-ascending dose cohorts of the ongoing Phase 1 trial in September.”

Dr. Struthers continued, “Looking forward, our strong financial foundation and talented team of in-house endocrinology experts leaves us well positioned to execute on our corporate and clinical objectives. Through the continued advancement of our pipeline, we aim to solidify our position as a leader in the design and development of novel small molecule drugs for endocrine diseases.”

Second Quarter and Subsequent Highlights

• Reported positive data from single-ascending dose (SAD) cohorts of first-in-human study of CRN04894. In August 2021, Crinetics announced positive data from the SAD cohorts of an ongoing Phase 1 study of its ACTH antagonist, CRN04894. Preliminary data provided evidence of clinically relevant cortisol suppression. CRN04894 demonstrated dose-dependent reductions in basal cortisol levels as well as suppression of cortisol following ACTH challenge. In addition, the data suggests that CRN04894 was orally bioavailable and demonstrated dose-proportional pharmacokinetics. CRN04894 was well-tolerated, and all adverse events were considered mild. The data is supportive of proceeding to the multiple-ascending dose cohorts of the Phase 1 study and additional data is expected in the fourth quarter of 2021.
• Commenced dosing in Phase 3 PATHFNDR-1 study. In June 2021, Crinetics announced that the first patient had been dosed in PATHFNDR-1, one of two planned Phase 3 trials assessing the safety and efficacy of once-daily oral paltusotine that together will evaluate paltusotine in a wide cross section of acromegaly patients. Topline data from PATHFNDR-1 is expected to be available in 2023.
• Strengthened balance sheet with successful common stock offerings. In April 2021, Crinetics completed an underwritten follow-on offering and raised gross proceeds of approximately $75.0 million and in August 2021, Crinetics entered into a securities purchase agreement with Frazier Healthcare Partners for the private placement of 851,306 shares at $17.62 per share, raising gross proceeds of $15.0 million.
• Appointed Garlan Adams as General Counsel. In June 2021, Crinetics strengthened its leadership team with the appointment of Ms. Adams to the newly created role of General Counsel. Ms. Adams brings more than two decades of experience managing legal and compliance matters associated with the development and commercialization of innovative pharmaceutical and biotechnology products.

Second Quarter 2021 Financial Results

• Research and development expenses were $20.5 million for the three months ended June 30, 2021, compared to $12.6 million for the same period in 2020. The increase was primarily due to an increase in personnel costs of $3.0 million, of which stock-based compensation was $1.1 million, and increased spending on manufacturing and development activities of $4.1 million associated with our clinical and nonclinical activities for paltusotine and our other clinical and preclinical programs.
• General and administrative expenses were $5.6 million for the three months ended June 30, 2021, compared to $4.3 million for the same period in 2020. The increase was primarily due to additional personnel costs of $0.8 million, of which stock-based compensation was $0.6 million.
• Net loss for the three months ended June 30, 2021 was $26.1 million, compared to a net loss of $16.5 million for the three months ended June 30, 2020.
• Unrestricted cash, cash equivalents and investments totaled $203.8 million as of June 30, 2021, compared to $170.9 million as of December 31, 2020. The increase was attributable to the $72.6 million net proceeds from the common stock offering completed in April.
• As of July 31, 2021, the company had 38,563,660 common shares outstanding.
