Summary
This trial is testing a gene therapy called valoctocogene roxaparvovec in patients with severe haemophilia A who have developed antibodies against standard treatments. The therapy aims to provide a working version of the gene needed for proper blood clotting.
Who is the study for?
This trial is for adult males with severe Hemophilia A who have had inhibitors to Factor VIII. They must not drink alcohol for a year post-treatment, use effective contraception, and cannot have other bleeding disorders or significant organ dysfunction. Part A includes those currently with inhibitors; Part B is for those with a past history of inhibitors.
What is being tested?
The study tests the safety and effectiveness of Valoctocogene Roxaparvovec in two groups: one with active Factor VIII inhibitors (Part A) and another that previously had these inhibitors but now tolerates FVIII (Part B).
What are the potential side effects?
Potential side effects may include immune reactions to the treatment, liver issues due to viral vector used in gene therapy, injection site reactions, headaches, fatigue, muscle pain and possibly new inhibitor development.

Other Research
Common treatments for Hemophilia A primarily aim to replace or bypass the deficient factor VIII (FVIII) to prevent or control bleeding episodes. Recombinant factor VIII products directly replace the missing FVIII, allowing the blood to clot properly.
Bypassing agents like activated prothrombin complex concentrate (aPCC) and recombinant factor VIIa (rFVIIa) work by activating the clotting cascade downstream of FVIII, effectively bypassing the need for FVIII. Gene therapy, such as valoctocogene roxaparvovec, introduces a functional FVIII gene into the patient's cells, enabling the body to produce its own FVIII.
This approach has the potential to provide a long-term solution by addressing the underlying genetic cause of Hemophilia A. These treatments are crucial for managing bleeding risks and improving the quality of life for patients with Hemophilia A.
