  excessive heart-muscle contraction and improve cardiac performance in patients
  with obstructive and non-obstructive HCM. The San Francisco-based company

  OrbiMed, Enavate Sciences, and Frazier Life Sciences, and filed for a Nasdaq
  IPO in July 2026. Braveheart Bio is a corporate/scientific organization and
