1. Organization and Business

Organization

Reneo Pharmaceuticals, Inc. (Reneo or the Company) commenced operations on September 22, 2014 as a pharmaceutical company and has historically focused on the development of therapies for patients with rare genetic mitochondrial diseases. In December 2017, the Company in-licensed mavodelpar (REN001), a novel oral peroxisome proliferator-activated receptor delta (PPARδ) agonist.

Risks and Uncertainties

On December 14, 2023, the Company announced that its pivotal STRIDE study, a global, randomized, double-blind, placebo-controlled Phase 2b trial of mavodelpar in adult patients with primary mitochondria myopathy due to mitochondrial DNA defects, did not meet its primary or secondary efficacy endpoints. As a result, the Company suspended the development activities of its only product candidate, mavodelpar, and implemented cash preservation activities, including substantial workforce reduction. In December 2023 and February 2024, the Company implemented a workforce reduction and recognized approximately $2.5 million and $1.6 million in severance and continuation of benefit expenses, respectively.
