SAN DIEGO – November 12, 2024 – Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX), a clinical stage pharmaceutical company focused on the discovery, development and commercialization of novel therapeutics for endocrine diseases and endocrine-related tumors, today reported financial results for the third quarter ended September 30, 2024.

“As we approach the end of 2024, it has been yet another remarkable year for Crinetics as we continued to consistently achieve key milestones to advance and expand our pipeline and strengthen the company’s position,” said Scott Struthers, Ph.D., Founder and Chief Executive Officer of Crinetics. “The submission of our first NDA was a significant milestone in the company’s history, and we remain on track for the expected launch of our investigational drug paltusotine for acromegaly in 2025, which will be a pivotal event for the company. The company’s core commitment to internal innovation continues to bear fruit with four new internally discovered drug candidates now in IND enabling activities, including the first candidate from our novel nonpeptide drug conjugate (NDC) targeted therapeutics platform emerging from our laboratories. We are excited to share preclinical data for this candidate intended for the treatment of SST2-expressing tumors at the North American Neuroendocrine Tumor Society (NANETS) Annual Meeting in Chicago on November 21-23. Further, subsequent to quarter end, we strengthened our already robust balance sheet by issuing additional equity, allowing us to invest in these promising early-stage programs, while continuing to fully support the anticipated launch of paltusotine and later-stage clinical development efforts.”

Third Quarter 2024 and Recent Highlights:

• Submitted New Drug Application (NDA) for paltusotine for the treatment of acromegaly. In September, Crinetics submitted an NDA to the U.S. Food and Drug Administration (FDA) for its investigational drug, paltusotine, the first once-daily, oral, selective somatostatin receptor type 2 nonpeptide agonist, for the proposed treatment of and long-term maintenance therapy for acromegaly. Crinetics anticipates receiving notification from the FDA on the status of the NDA submission in December 2024.
• Strengthened balance sheet with $575 million public offering. In October, Crinetics completed an upsized public offering of common stock for gross proceeds of $575 million.
• Selected development candidate in TSH antagonist program. Crinetics has identified an oral thyroid stimulating hormone (TSH) receptor antagonist for the potential treatment of Graves’ disease and thyroid eye disease. First-in-human-enabling studies have commenced and an Investigational New Drug (IND) filing is expected in 2025.
• Data from CRN09682, the first drug candidate from novel Nonpeptide Drug Conjugate (NDC) platform, to be presented at the North American Neuroendocrine Tumor Society (NANETS) in November 2024. First-in-human-enabling activities are nearing completion and IND filing is expected in early 2025.
• Total of four development candidates currently in IND-enabling studies to support transition to clinical development in 2025.

Key Upcoming Milestones

• Additional data from the Phase 2 study of its investigational drug atumelnant* in CAH is anticipated by early 2025.
• Crinetics expects to finalize a Phase 3 protocol and initiate site startup activities for its investigational drug paltusotine in carcinoid syndrome by the end of 2024.

Third Quarter 2024 Financial Results

• Research and development expenses were $61.9 million for the three months ended September 30, 2024, compared to $43.8 million for the same period in 2023. The increase was primarily attributable to higher personnel costs, outside services costs, and manufacturing activities costs, all of which were driven by the advancement of our clinical programs and the expansion of our preclinical portfolio.
• General and administrative expenses were $25.9 million for the three months September 30, 2024, compared to $15.5 million for the same period in 2023. The increase was primarily driven by higher personnel costs and outside services costs.
• Net loss for the three months ended September 30, 2024, was $76.8 million, compared to a net loss of $57.5 million for the same period in 2023.
• There were no revenues during the three months ended September 30, 2024, compared to revenues of $0.3 million for the same period in 2023. Third quarter 2023 revenues were derived from the paltusotine licensing arrangement with our Japanese partner, Sanwa Kagaku Kenkyusho (SKK).
• Cash, cash equivalents, and investment securities totaled $862.7 million as of September 30, 2024, compared to $558.6 million as of December 31, 2023. On October 10, 2024, the Company completed an upsized underwritten public offering of common stock for gross proceeds of $575 million, strengthening its financial position with approximately $1.4 billion in cash, cash equivalents and investment securities. Based on current projections, Crinetics expects that its cash, cash equivalents and investment securities will be sufficient to fund its current operating plan into 2029.
