Del-desiran, designed to address DM1's underlying genetic cause, has received multiple regulatory designations including Breakthrough Therapy, Orphan Drug, and Fast Track from the FDA. The HARBOR trial involves approximately 150 patients across 40 global sites, evaluating the drug's efficacy through various endpoints including video hand opening time (vHOT) and muscle strength measurements.

The Phase 1/2 EXPLORE44 trial demonstrated significant results, including statistically significant increases in exon skipping, substantial increase in dystrophin production, and significant reduction in creatine kinase levels to near normal. The company plans to present topline and functional data from the Phase 2 EXPLORE44-OLE trial in Q4 2025.

Del-zota has also received Orphan designation from FDA and EMA, plus Rare Pediatric Disease and Fast Track designations from FDA for DMD44 treatment.

The trial evaluated 39 participants across two dose cohorts (2mg/kg and 4mg/kg) over 12 months. Key findings include improved 10-Meter Walk-Run test, Timed Up and Go, and quantitative muscle testing scores, along with significant reductions in KHDC1L and creatine kinase biomarkers. The company plans to submit a BLA for accelerated approval in H2 2026 and has initiated the Phase 3 FORWARD study. FSHD affects 45,000-87,000 people in the US and Europe, with no currently approved treatments.
