Ethnic evaluation of the pharmacokinetics and safety of new drugs is required in Japan before implementing bridging or joining global studies. As therapeutic monoclonal antibodies (mAbs) show limited ethnic differences, their pharmacokinetics and safety in Japanese individuals could be estimated from prior non-Japanese studies. Therefore, there is potential(More)
ACE910 is a recombinant humanized bispecific antibody that binds to activated factor IX and factor X and mimics the cofactor function of factor VIII (FVIII). This first-in-human study examined the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of ACE910 in healthy male adults. A total of 40 Japanese and 24 white subjects were(More)
BACKGROUND In patients with severe hemophilia A, standard treatment is regular prophylactic and episodic intravenous infusions of factor VIII. However, these treatments are burdensome, especially for children, and may lead to the formation of anti-factor VIII alloantibodies (factor VIII inhibitors). Emicizumab (ACE910), a humanized bispecific antibody(More)
