Epicrispr secures $90M after early data on epigenetic FSHD treatment | 2026-08-11

Epicrispr Biotechnologies has raised $90 million in a Series C round led by Octagon Capital and Janus Henderson Investors, with participation from Sanofi Ventures and several other healthcare investors.

The financing follows early clinical data from its Phase 1/2 trial of EPI-321, an epigenetic editing therapy for facioscapulohumeral muscular dystrophy (FSHD), showing increased lean muscle mass and biomarker changes consistent with suppression of the pathogenic DUX4 gene.

EPI-321 uses CRISPR-based epigenetic editing delivered via a single intravenous adeno‑associated virus (AAV) vector to durably silence DUX4 expression without cutting or permanently altering DNA, positioning it as a potential one‑time, disease‑modifying treatment for FSHD.

The company plans to use the $90 million to advance EPI-321 into pivotal (registrational) studies while expanding its pipeline of programmable epigenetic medicines for other indications.
