We are disappointed to report that PTC Therapeutics has withdrawn its New Drug Application for Translarna™ (ataluren) for the treatment of nonsense mutation DMD after feedback from the FDA that the data are insufficient to meet the standard for approval. The company is expected to inform the community in the coming weeks of next steps for those currently receiving Ataluren therapy.
We are deeply grateful to the families who participated in clinical trials and to the team at PTC who dedicated years of work to advancing this research. Progress in Duchenne is only possible because of that commitment.
CureDuchenne stands with every family impacted, and we remain committed to accelerating promising research and expanding options so that no one with Duchenne is left behind.
