Official title

A Phase II/III, Randomized, Cross-over, Open-label Trial to Demonstrate Superiority of Prophylaxis Over On-demand Therapy in Previously Treated Subjects With Severe Hemophilia A Treated With Plasma Protein-free Recombinant FVIII Formulated With Sucrose (BAY 81-8973)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The objective of the trial is to demonstrate that 2-3 times per week prophylaxis therapy with BAY81-8973 is superior to on-demand therapy with BAY81-8973 in patients with severe Hemophilia A. The hypothesis is that prophylaxis will result in fewer bleeds than on-demand treatment.
