  • Study Participants

SIG-001-121 is a first-in-human (FIH), phase 1/2, multi-centre, open-label, dose escalation study to assess the safety, tolerability, and preliminary efficacy of SIG-001 in adults with severe or moderately severe haemophilia A without inhibitors. Up to three dose cohorts (3 patients each) are planned. Cohort expansions (up to 3 additional patients) may be triggered to collect additional information about safety and efficacy.
