Pharmacokinetics Evaluation of Recombinant Coagulation Factor VIII Injection in Subjects With Hemophilia A.

Phase 1
Conditions
Hemophilia A
Interventions
Drug: Recombinant Coagulation Factor VIII Injection
Registration Number
NCT04060836
Lead Sponsor
Chia Tai Tianqing Pharmaceutical Group Co., Ltd.
Brief Summary

This is a multi-center, open-label, randomized study. Participants will be assigned to A or B groups with a scale of 1:1 , i.e. infuse study drug followed by Xyntha (group A), or the alternate sequence (group B). All participants who completed the study will enter the Prophylactic Therapy Study.
