215 minor and 18 major surgeries were performed in patients receiving HEMLIBRA²

Unplanned surgeries and elective minor procedures were allowed in the HAVEN study programme and were managed at the investigator’s discretion. No major or minor surgical procedure resulted in death, thrombosis, FVIII inhibitor development, or an unexpected bleed.²

The safety and efficacy of HEMLIBRA have not been formally evaluated in the surgical setting.¹

126 patients receiving HEMLIBRA had at least one surgical procedure. HAVEN 1, n=38 of 113* adults and adolescents with inhibitors; HAVEN 2, n=27 of 88 paediatrics with inhibitors; HAVEN 3, n=45 of 152 adults and adolescents without inhibitors; HAVEN 4, n=16 of 48 adults and adolescents with and without inhibitors.²

*One participant in HAVEN 1 discontinued prior to treatment.

The surgery analysis includes more patients than the primary efficacy analyses, due to later data cut-offs of 2–11^th October 2018.^2,3 All data available at time of presentation are included here.
