A Phase 3 trial of a gene treatment developed by Pfizer and Sangamo Therapeutics for the blood condition haemophilia A will shortly resume, nearly a year after it was put on hold due to safety concerns. 

The businesses specifically stated Thursday night that they intended to begin patient enrollment in the study this month and resume treatment administration in October.

The trial was initially put on hold last fall because of worries about blood clotting and safety. Giroctocogene fitelparvovec, a type of gene therapy, is used to treat persons with severe haemophilia A who are either deficient in or have low amounts of a crucial blood clotting protein. 

Some patients experienced higher-than-normal levels of that blood clotting protein as a result of treatment, and many were consequently prescribed oral blood thinners. Later, Pfizer revealed that one patient had higher clotting protein levels combined with deep vein thrombosis in the leg.

After Pfizer and Sangamo changed their trial protocol, the Food and Drug Administration lifted a clinical hold it had placed in May, enabling testing to continue.

The two firms now anticipate a slightly later resumption after having hoped to resume dosing around the end of September. Trial data, which had been anticipated for 2023, is now anticipated in early 2024, Pfizer announced on Thursday.
