Item 7.01 Regulation FD Disclosure.

On September 10, 2023, Crinetics Pharmaceuticals, Inc. (the “Company” or “Crinetics”) issued a press release and made available a corporate presentation announcing topline results from its Phase 3 PATHFNDR-1 study (NCT04837040). Copies of the press release and corporate presentation are attached as Exhibits 99.1 and 99.2, respectively, to this report. The corporate presentation will also be available under the “Investors” section of the Company’s website. The Company intends to deliver the corporate presentation during a conference call and live webcast with the investment community on September 11, 2023, at 8:00 a.m. Eastern Time.

The information contained in this Item 7.01, including in Exhibits 99.1 and 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 September 10, 2023, Crinetics announced that paltusotine, an oral, once-daily investigational compound, achieved positive results by meeting the primary endpoint and all secondary endpoints of the Phase 3 PATHFNDR-1 study (NCT04837040). PATHFNDR-1 was a randomized, double-blind, placebo-controlled 36-week treatment period followed by an optional open label extension study evaluating paltusotine in participants with acromegaly switching from standard-of-care injected depot somatostatin analogs. The study enrolled participants with acromegaly who were biochemically controlled on octreotide or lanreotide depot monotherapy. PATHFNDR-1 is one of two ongoing, placebo-controlled Phase 3 studies of once-daily, oral paltusotine.

The study met statistical significance (p<0.0001) on the primary endpoint, based on the proportion of participants taking paltusotine (83%) who maintained an insulin-like growth factor 1 (IGF-1) level ≤ 1.0 times the upper limit of normal (xULN) compared to those taking placebo (4%). All secondary endpoints also met statistical significance: change from baseline in IGF-1 level (xULN) (p<0.0001), change from baseline in Acromegaly Symptoms Diary (ASD) total score (p=0.02) and proportion of participants who maintained a growth hormone (GH) level of <1.0ng/mL (p=0.0003).

In PATHFNDR-1, paltusotine was well tolerated and no serious or severe adverse events were reported in participants treated with paltusotine. The frequency of participants with at least one treatment emergent adverse event (TEAE) was comparable in the paltusotine (PAL) treatment arm vs. placebo (PBO) arm (80% vs. 100% respectively). The most commonly reported TEAEs in paltusotine included: arthralgia (27% PAL vs. 57% PBO), headache (20% PAL vs. 36% PBO), diarrhea (23% PAL vs. 14% PBO), abdominal pain (17% PAL vs. 11% PBO) and nausea (10% PAL vs. 7% PBO). The frequency of adverse events considered related to acromegaly was notably lower in paltusotine treated participants compared to placebo treated participants (30% vs. 86% respectively).

A full analysis of the PATHFNDR-1 results is underway, which the Company expects to present at upcoming scientific conferences. PATHFNDR-2, a Phase 3 study of oral paltusotine in participants with acromegaly who are treatment-naïve or not currently receiving medical therapy, is fully enrolled and topline data are expected in the first quarter of 2024. Pending successful findings from the PATHFNDR-2 study, Crinetics plans to submit a new drug application to the U.S. Food and Drug Administration in 2024 seeking regulatory approval for all acromegaly patients who require pharmacotherapy, including newly diagnosed patients and those switching from other therapies.

The Company is also conducting an open-label Phase 2 study to evaluate paltusotine in patients with carcinoid syndrome and expects to report interim results later this year.

The PATHFNDR Program consists of two Phase 3 double-blind, placebo-controlled studies. PATHFNDR-1 (NCT04837040) enrolled a total of 58 adults with acromegaly who entered with an IGF-1 level ≤ 1.0 xULN on octreotide or lanreotide depot monotherapy. They were randomized to receive once-daily, oral paltusotine for 36 weeks or placebo. PATHFNDR-2 (NCT05192382) enrolled 112 adults with acromegaly who had elevated IGF-1 levels but were medication na��ve or were not being treated with pharmacotherapy (untreated patients).

The primary endpoint for both studies is the proportion of patients achieving IGF-1 ≤1.0 xULN compared to placebo. If successful, Crinetics believes these studies 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.
