Preventive treatment with factor VIII (FVIII) — the missing blood clotting protein in hemophilia A — was not fully effective at preventing MRI-detected joint changes in boys with severe disease, according to a Canadian study. Regular evaluation of joints by MRI or ultrasounds, however, may help in identifying those…

A single dose of the experimental gene therapy AMT-180 promotes clinically meaningful blood-clotting activity, independent of factor VIII levels, in mouse and primate models of hemophilia A, a study shows.
