ANNEXa-1 (18-513): This is a randomized, multicenter clinical trial designed to determine the efficacy and safety of andexanet compared to usual care in patients presenting with acute intracerebral hemorrhage within 6 hours of symptom onset (from the baseline scan) and within 15 hours of taking an oral FXa inhibitor (from randomization). The study will use a prospective, randomized, open-label design, as it is unfeasible to blind the Investigator to the treatment assignment given the many potential therapeutic options available under usual care treatment.
