Item 8.01 Other Events.

On March 14, 2023, Reneo Pharmaceuticals, Inc. (the “Company”) announced the achievement of the target enrollment of its STRIDE study. The STRIDE study is a global, randomized, double-blind, placebo-controlled pivotal Phase 2b trial of mavodelpar in adult patients with primary mitochondrial myopathies (“PMM”) due to mitochondrial DNA (“mtDNA”) defects. The STRIDE study is designed to assess the efficacy and safety of 100 mg mavodelpar administered orally, once daily for 24 weeks. The primary efficacy endpoint is the change from baseline in the distance walked during the 12-minute walk test at week 24. Topline data from the STRIDE study are expected in the fourth quarter of 2023.

STRIDE AHEAD is a 24-month, open-label, long-term safety trial outside of the United States in patients with PMM. The STRIDE AHEAD study was recently amended to allow enrollment of patients with PMM due to both mtDNA and nuclear DNA defects.

The Company intends to submit the data from STRIDE, together with the long-term safety data from STRIDE AHEAD, to the U.S. Food and Drug Administration and the European Medicines Agency in planned marketing applications in 2024.
