A Multicenter, Randomized, Open-Label, Phase III Clinical Trial to Evaluate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of NXT007 Prophylaxis Versus Factor VIII Prophylaxis in People With Hemophilia A Without Inhibitors
The purpose of this study is to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of NXT007 prophylaxis compared with Factor VIII (FVIII) prophylaxis in participants with severe or moderate congenital hemophilia A without inhibitors. The study will include people aged ≥12 years old with severe or moderate congenital hemophilia A without inhibitors on previous FVIII prophylaxis treatment.
• Diagnosis of severe (FVIII:C \<1 IU/dL \[International Unit per decilitre\]) or moderate (FVIII:C between ≥1 IU/dL and ≤5 IU/dL) congenital hemophilia A without inhibitors against FVIII
• No documented inhibitor (i.e., \<0.6 BU/mL \[Bethesda unit per millilitre\]), FVIII half-life ≥6 hours, or FVIII recovery \>66% in the last 3 years prior to screening
• Documented historical negative test for FVIII inhibitor (i.e., \<0.6 BU/mL) within 12 months prior to enrollment
• Documentation of the details of prophylactic and episodic FVIII treatment and of the number and type of bleeding episodes for at least the last 6 months prior to screening
• Agreement to adhere to the contraception requirements (for potential participants with childbearing potential)
