More about Cure Rare Disease

CRD-003 received FDA orphan drug designation in September 2025 and a $7.4 million grant from the California Institute for Regenerative Medicine in December 2025. CRD-002 received orphan drug designation in May 2025. Neither program had a trial listed on ClinicalTrials.gov in October 2026.

Its earlier Duchenne muscular dystrophy study (CRD-TMH-001, NCT05514249) treated a single patient with a custom CRISPR-based gene therapy developed with researchers at Yale School of Medicine and UMass Chan Medical School. The study ended when its only participant, a 27-year-old man, died in October 2022, 8 days after treatment.

A 2023 report in the New England Journal of Medicine concluded that an innate immune reaction caused acute respiratory distress syndrome after the high-dose AAV9 gene therapy.
