MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Non-factor therapies are a novel treatment approach for people with hemophilia A and B with and without inhibitors.
Fitusiran is a first-of-its-kind “rebalancing” agent that provides effective hemostatic control from bleeds in people with hemophilia. This study describes the experience of people with hemophilia who are on fitusiran in regard to minor surgeries. This data shows minor surgeries can be effectively and safely performed for those patients who are on fitusiran for their prophylaxis. A subset of individuals on fitusiran did not require any other medications to help prevent surgical bleeding.

Medical Research: What is the background for this study? What are the main findings?
Dr. Santagostino: Two of our abstracts presented at the 57th ASH Annual Meeting are part of the PROLONG-9FP clinical program evaluating the efficacy and safety of CSL Behring’s investigational long-acting fusion protein linking recombinant coagulation factor IX with recombinant albumin (rIX-FP). The first is an oral presentation on results from two Phase III studies and an ongoing extension study of rIX-FP for routine prophylaxis in previously-treated people with
