Item 2.02 Results of Operations and Financial Condition.

On August 10, 2021, Crinetics Pharmaceuticals, Inc. (the “Company” or “Crinetics”) issued a press release reporting its financial results for the quarter ended June 30, 2021. The full text of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K.

In accordance with General Instruction B.2 of Form 8-K, the information contained or incorporated herein, including the press release filed as Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof, except as expressly set forth by specific reference in such filing to this Current Report on Form 8-K.

Item 7.01 Regulation FD Disclosure.

The slides attached as Exhibit 99.2 to this Current Report contain certain additional information related to the clinical data results discussed in Item 8.01 below. Crinetics intends to present the slides during a conference call and live webcast with the investment community on August 10, 2021, at 4:30 p.m. Eastern Time.

The information contained in this Item 7.01, including in Exhibit 99.2 hereto, is being “furnished” and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, is not subject to the liabilities of that section and is not deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except as shall be expressly set forth by specific reference in such a filing.

Item 8.01 Other Events.

On August 10, 2021, Crinetics announced positive preliminary findings from the single ascending dose (SAD) portion of a first-in-human Phase 1 clinical study with CRN04894 demonstrating pharmacologic proof-of-concept for this first-in-class, investigational, oral, nonpeptide adrenocorticotropic hormone (ACTH) antagonist that is being developed for the treatment of conditions of ACTH excess, including Cushing’s disease and congenital adrenal hyperplasia.

The 39 healthy volunteers who enrolled in the SAD cohorts were administered oral doses of CRN04894 (10 mg to 80 mg, or placebo) two hours prior to a challenge with synthetic ACTH. Analyses of basal cortisol levels (before ACTH challenge) showed that CRN04894 produced a rapid and dose-dependent reduction of cortisol by 25-56%. After challenge with a supra-pathophysiologic dose of ACTH (250 mcg), CRN04894 suppressed cortisol (as measured by AUC) up to 41%. After challenge with a disease-relevant dose of ACTH (1 mcg), CRN04894 showed a clinically meaningful reduction in cortisol AUC of 48%. These reductions in cortisol suggest that CRN04894 is bound with high affinity to its target receptor on the adrenal gland and blocking the activity of ACTH. CRN04894 was well tolerated in the healthy volunteers who enrolled in these SAD cohorts and all adverse events were considered mild.

Forward-Looking Statements

Crinetics cautions you that statements contained in this press release regarding matters that are not historical facts are forward-looking statements. These statements are based on the company’s current beliefs and expectations. Such forward-looking statements include, but are not limited to, statements regarding: the potential benefits of CRN04984 for patients with conditions of ACTH excess, including Cushing’s disease and congenital adrenal hyperplasia; the design and timing of data from the Phase 1 clinical trial of CRN04984; plans to advance paltusotine into a Phase 2 trial for the treatment of carcinoid syndrome associated with neuroendocrine tumors; and plans to advance other pipeline product candidates and to invest in the small molecule discovery approach. The inclusion of forward-looking statements should not be regarded as a representation by Crinetics that any of its plans will be achieved. Actual results may differ from those set forth in this press release due to the risks and uncertainties inherent in Crinetics’ business, including, without limitation: preliminary data that we report may change following a more comprehensive review of the data related to the clinical trials and such data may not accurately reflect the complete results of a clinical trial, and the FDA and other regulatory authorities may not agree with our interpretation of such results; advancement of CRN04894 into later stage trials are dependent on and subject to the receipt of further feedback from the FDA; we may not be able to obtain, maintain and enforce our patents and other intellectual property rights, and it may be prohibitively difficult or costly to protect such rights; the COVID-19 pandemic may disrupt Crinetics’ business and that of the third parties on which it depends, including delaying or otherwise disrupting its clinical trials and preclinical studies, manufacturing and supply chain, or impairing employee productivity; the company’s dependence on third parties in connection with product manufacturing, research and preclinical and clinical testing; the success of Crinetics’ clinical trials and nonclinical studies for paltusotine, CRN04894, CRN04777, and its other product candidates; regulatory developments in the United States and foreign countries; unexpected adverse side effects or inadequate efficacy of the company’s product candidates that may limit their development, regulatory approval and/or commercialization; Crinetics may use its capital resources sooner than it expects; and other risks described under the heading “Risk Factors” in documents the company files from time to time with the Securities and Exchange Commission.

Crinetics Pharmaceuticals Reports Second Quarter 2021 Financial Results

and Provides Corporate Update

– Commenced dosing in Phase 3 PATHFNDR-1 study –

– Phase 1 single-ascending dose data demonstrate the dose-dependent and clinically-significant pharmacodynamic effects of CRN04894 –

– Phase 1 data for CRN04777 expected in September –  

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.”
