Wave Life Sciences’ WVE-N531 Shows Promise in Duchenne Muscular Dystrophy Treatment
Wave Life Sciences reported positive 48-week data from the Phase II FORWARD-53 trial of WVE-N531 in DMD patients amenable to exon 53 skipping12.
The trial met all endpoints, demonstrating sustained exon skipping, reversed muscle fibrosis, and restored dystrophin in participants4.
WVE-N531 showed a mean dystrophin expression of 7.8% between weeks 24 and 48, with 88% of boys achieving above 5% average dystrophin8.
Patients experienced a statistically significant 3.8-second improvement in time-to-rise tests compared to natural history28.
The drug demonstrated a 28.6% reduction in muscle fibrosis between weeks 24 and 48, marking the first significant reversal observed with an exon-skipping therapy58.
Wave Life Sciences plans to file a New Drug Application (NDA) with the FDA in 2026 for accelerated approval of WVE-N53148.
The company intends to submit data supporting monthly dosing in the NDA, based on the drug's 61-day tissue half-life68.
WVE-N531 continues to show a favorable safety profile with no serious adverse events reported8.
Wave is also accelerating programs for multiple DMD candidates targeting other exons, with plans to file clinical trial applications for some candidates next year4.
The positive results position WVE-N531 as a potential first-line treatment for patients amenable to exon 53 skipping8.
