What are the latest advances in Factor V Deficiency?

Factor V deficiency, also known as Owren's disease, is a rare bleeding disorder currently managed primarily through supportive care like fresh frozen plasma (FFP) rather than targeted curative therapies. While no specific gene therapy is currently approved, research is increasingly focusing on recombinant factor concentrates and advanced coagulation monitoring to improve outcomes for those living with Factor V deficiency.

What are the current research priorities for Factor V deficiency?

Because Factor V deficiency is exceptionally rare—affecting approximately 1 in 1,000,000 individuals—large-scale clinical trials are difficult to conduct. Current research is shifting toward the development of high-purity, virus-inactivated plasma-derived or recombinant factor concentrates. Researchers are also investigating the use of global coagulation assays, such as thrombin generation tests, to better predict bleeding risks in patients with Factor V deficiency, as standard lab tests often fail to correlate perfectly with clinical symptoms.

Are there new treatments on the horizon?

While definitive cures remain in the early research stages, the field is advancing through personalized medicine. Current therapeutic developments include:

• Recombinant Factor V: Investigational products are being studied to provide a safer alternative to pooled human plasma.


• Hemostatic Agents: Exploring the use of recombinant activated factor VII (rFVIIa) as an adjunct therapy for severe bleeding episodes in Factor V deficiency patients.


• Antifibrinolytics: Refined protocols for using tranexamic acid to manage mucosal bleeding, which is a common challenge for those with Factor V deficiency.

How can patients contribute to research?

Participation in clinical research is vital for rare diseases like Factor V deficiency. Patients can contribute by joining disease registries, which collect longitudinal data to help researchers understand the natural history of the condition. You can search for studies on ClinicalTrials.gov using the term "Factor V deficiency" to identify active trials or observational studies.
