Core Viewpoint - Biohaven's stock experienced a significant increase of over 6% following positive regulatory news from the FDA regarding its New Drug Application for troriluzole, outperforming the S&P 500 index's 1.5% gain on the same day [1]. Regulatory Progress - Biohaven disclosed in a filing with the SEC that the FDA informed the company that an advisory committee meeting for the New Drug Application (NDA) for troriluzole is no longer necessary [2]. - Troriluzole is aimed at treating spinocerebellar ataxia, a group of inherited neurological disorders affecting movement, and the drug's development faced initial setbacks, including the FDA's refusal to accept the filing [4].
