Recombinant-activated coagulation factor VIIa (NovoSeven®): current development

Recombinant activated coagulation factor VII (rFVIIa) was developed initially for treatment of patients with hemophilia and neutralizing antibodies (“inhibitors”) to coagulation factors VIII or IX. Owing to the unique and selective mechanism of action of rFVIIa and encouraged by clinical experience with other circumstances of inadequate hemostasis, a broad development program has been pursued to test potential efficacy and evaluate safety of this biologic for indications other than hemophilia. This review summarizes the current development of rFVIIa, focusing on results of prospective, randomized clinical trials.
