Biohaven says FDA accepted troriluzole NDA resubmission for SCA; advisory committee planned
Biohaven said the FDA accepted its new drug application resubmission for Vyglxia (troriluzole) in spinocerebellar ataxia (SCA) and considers it a complete response to the November 4, 2025 action letter. The FDA set a user fee goal date in the first quarter of 2027 and plans an advisory committee meeting, with the date to be announced later, so approval is not assured.
