The efficacy of HYMPAVZI for patients 12 years and older was established in 116 people with hemophilia A or B without inhibitors in the phase 3 BASIS study. The study consisted of a 6-month observational period (when the people were taking either on-demand factor replacement treatment or routine factor-based prophylactic treatment) followed by a 12-month active treatment phase with HYMPAVZI.

Participants

adults and adolescent males ages 12+ with severe hemophilia A or moderately severe to severe hemophilia B without inhibitors

routine factor-based prophylaxis participants

on-demand factor-based treatment participants

BASIS KIDS

BASIS KIDS is an ongoing trial that is studying HYMPAVZI in children, including those ages 6 to less than 18 with hemophilia A or B, with or without inhibitors

BASIS KIDS study overview—with or without inhibitors

The efficacy of HYMPAVZI was established in 57 children and adolescents ages 6 to less than 18 years of age with severe hemophilia A or moderately severe to severe hemophilia B, with or without inhibitors, in the BASIS KIDS study. The study consisted of a 12-month active treatment phase with HYMPAVZI. BASIS KIDS is an ongoing clinical study. Inhibitor participants with historic routine bypass therapy prophylaxis were not part of prespecified primary efficacy analysis, but were included in the safety analyses.

51 adults and adolescents entered the observational phase. The efficacy of HYMPAVZI for patients 12 years and older was established in 48 people with hemophilia A or B with inhibitors. The study consisted of a 6-month observational period (when people were either taking on-demand or prophylactic treatment with bypassing agents) followed by a 12-month active treatment phase with HYMPAVZI. Inhibitor participants with historic routine bypass therapy prophylaxis were not part of prespecified primary efficacy analysis, but were included in the safety analyses.
