Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

For bridging the available global clinical data of rVIII-SingleChain, with the Chinese population, the aim of this study in China is to investigate the pharmacokinetics (PK) of rVIII-SingleChain after an initial and repeat dose and to assess efficacy and safety during 2 to 3 times weekly prophylaxis treatment with rVIII-SingleChain in male Chinese PTPs with severe hemophilia A (FVIII activity less than \[\<\] 1%).
