August 16, 2019 updated by: Chia Tai Tianqing Pharmaceutical Group Co., Ltd.

Randomized, Open-label, Double Cycle, Crossover, Pharmacokinetics Study of Recombinant Coagulation Factor VIII Injection Versus Xyntha® in Subjects With Hemophilia A.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
