Limits of the Current Standard of Care

  • Nimodipine, an insoluble dihydropyridine calcium channel blocker, is the only FDA approved pharmacotherapy known to improve outcomes in aSAH.

  • In the US, it is available as large capsules or liquid solution which is administered orally every four hours for up to 21 days. In critically ill patients, this presents significant problems:
    • Heavy dosing burden due to high first pass metabolism
    • Poor hypotension management and frequent dose interruption
    • Nasogastric tube delivery in unconscious or dysphagic patients
    • Food effects and contraindicated with CYP3A inhibitors
    • High pharmacokinetic variability with oral route


  • Acasti has developed a breakthrough formulation of nimodipine that enables an intravenous infusion in aSAH patients, potentially solving the clinical problems with oral administration.

  • The program is currently enrolling patients in the pivotal Phase 3 safety trial (STRIVE-ON).

  • Potential value for patients, physicians, and hospitals - 
    • Improve outcomes
    • Effective patient management
    • Reduced cost of care
