Safety and Efficacy of N8 in Haemophilia A Subjects
A Multi-centre, Open-label, Non-controlled Trial on Safety and Efficacy of N8 in Prevention and Treatment of Bleeds in Previously Treated Subjects With Haemophilia A. Sub-trial: Safety and Efficacy of N8 in Prevention and Treatment of Bleeding During Surgical Procedures in Subjects With Haemophilia A

This trial is conducted in Africa, Asia, Europe, Japan, Oceania, and North and South America.

The trial consists of a main trial and a sub-trial. The main trial investigates safety and efficacy of recombinant factor VIII (N8) in haemophilia A subjects, while the sub-trial investigates safety and efficacy of N8 in prevention and treatment of bleeding during surgical procedures.

Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
  • Congenital Bleeding Disorder
