Updates PTC Therapeutics FA programme
In August 2025, PTC Therapeutics announced that the US drug regulators the FDA did not approve their drug vatiquinone to treat adults and children with Friedreich’s ataxia (FA). The FDA said that substantial evidence of the drug’s effectiveness was not demonstrated, and an additional clinical trial is needed. In February 2026, PTC Therapeutics provided an update via press release. This update explained that in December 2025, as planned, they had a meeting with the FDA to discuss next steps. The FDA indicated to PTC Therapeutics that an additional study is needed to support them resubmitting an NDA (New Drug Application) for vatiquinone, and that this could be an open-label study with a natural history control group.
