Reneo Pharmaceuticals Achieves Target Enrollment in the Pivotal STRIDE Study of Mavodelpar (REN001) in Primary Mitochondrial Myopathies

Topline data from the STRIDE study expected in the fourth quarter of 2023

IRVINE, Calif., March 14, 2023 (GLOBE NEWSWIRE) — Reneo Pharmaceuticals, Inc. (Nasdaq: RPHM), a clinical-stage pharmaceutical company focused on the development and commercialization of therapies for patients with rare genetic mitochondrial diseases, today announced that the company has achieved the target enrollment in the pivotal STRIDE study of mavodelpar (REN001) in primary mitochondrial myopathies (PMM). Topline data from the STRIDE study are expected in the fourth quarter of 2023.

“We are very pleased to announce dosing of the 200th patient in the ongoing STRIDE study,” said Gregory J. Flesher, President and CEO of Reneo Pharmaceuticals. “We achieved our target enrollment and have several pending patients that are awaiting their baseline visit. As such, we anticipate total enrollment of more than 200 patients and topline results in the fourth quarter of 2023. We are also pleased to see that approximately 85% of the eligible patients from STRIDE have opted to participate in STRIDE AHEAD, the mavodelpar two-year safety study.”

STRIDE is a global, randomized, double-blind, placebo-controlled pivotal Phase 2b trial of mavodelpar in adult patients with PMM due to mitochondrial (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.

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 (nDNA) defects.

Reneo 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 (FDA) and the European Medicines Agency (EMA) in planned marketing applications in 2024.

About Reneo Pharmaceuticals

Reneo is a clinical-stage pharmaceutical company focused on the development and commercialization of therapies for patients with rare genetic mitochondrial diseases, which are often associated with the inability of mitochondria to produce adenosine triphosphate (ATP). Our lead product candidate, mavodelpar, is a potent and selective agonist of the peroxisome proliferator-activated receptor delta (PPARδ). Mavodelpar has been shown to increase transcription of genes involved in mitochondrial function and increase fatty acid oxidation (FAO), and may increase production of new mitochondria.

About Mavodelpar

Mavodelpar (REN001) is a potent and selective peroxisome proliferator-activated receptor delta (PPARδ) agonist currently in clinical development for two rare genetic mitochondrial diseases that typically present with myopathy and have high unmet medical needs: primary mitochondrial myopathies (PMM) and long-chain fatty acid oxidation disorders (LC-FAOD). For additional information, please see

About PMM

PMM are a group of rare, genetic metabolic disorders caused by mutations or deletions in the mitochondrial DNA (mtDNA) or nuclear DNA (nDNA). These genetic alterations hamper the ability of mitochondria to generate energy from nutrient sources, resulting in energy deficits that are most pronounced in tissues with high energy demand such as muscle, brain, and heart. The symptoms of PMM include muscle weakness, exercise intolerance, movement disorder, deafness, blindness, and droopy eyelids among others. The prognosis for these disorders ranges in severity from progressive weakness to death.
