Haemophilia Treatment Pathway

See where clinical trials fit into your treatment journey

Standard Prophylaxis

Regular factor replacement

Standard: Recombinant Factor VIII (Haemophilia A) or Factor IX (Haemophilia B)

Extended Half-Life

Less frequent dosing

Standard: Efmoroctocog alfa, Eftranonacog alfa, or other EHL products

Non-Factor Therapy

Bypassing factor altogether

Standard: Emicizumab (Hemlibra) — bispecific antibody mimicking Factor VIIIa

Gene Therapy

One-time curative treatment

Standard: AAV-based gene transfer (Valoctocogene roxaparvovec for Haem A, Etranacogene dezaparvovec for Haem B)

About Haemophilia

Haemophilia A

Deficiency of Factor VIII. About 80% of haemophilia cases. Standard treatment is regular Factor VIII infusions, but Emicizumab and gene therapy are changing the landscape.

Haemophilia B

Deficiency of Factor IX. Less common but treatment advances including extended half-life factors and gene therapy are significant.

With Inhibitors

About 30% of severe Haemophilia A patients develop inhibitors (antibodies) against replacement factor. Emicizumab has been transformative for this group.

Frequently Asked Questions

Gene therapy aims to enable the body to produce its own clotting factor. Early results show significant factor level increases lasting 3-5+ years. Research is ongoing into long-term durability and whether re-treatment is possible.

Emicizumab is a bispecific antibody that mimics Factor VIII function. It is approved on the NHS but trials are exploring longer-acting formulations and use in patients without inhibitors.

Gene therapy trials for haemophilia have primarily enrolled adults. However, paediatric trials are beginning as safety data matures. Discuss with your haemophilia centre what options are available for children.
