There were 62 previously treated adolescents and adults (aged 12 to 65 years) with severe hemophilia A in LEOPOLD I, studied for 1 year.1
Doctors studied, choosing either 2x/week (18 people) or 3x/week prophylaxis (44 people) based on people's needs.1
People who were chosen to start a 2x/week regimen had a prior history of fewer bleeds and a lower percentage of target joints than people chosen for a 3x/week regimen.2
Doctors chose a dose based on the individual person's needs. They didn't need to test pharmacokinetic activity (drug activity in the body) to find the right dose.1,2
KOVALTRY® is a medicine used to replace clotting factor (Factor VIII or antihemophilic factor) that is missing in people with hemophilia A.
KOVALTRY® is used to treat and control bleeding in adults and children with hemophilia A. KOVALTRY® can reduce the number of bleeding episodes in adults and children with hemophilia A when used regularly (prophylaxis). Your healthcare provider may give you KOVALTRY® when you have surgery.
KOVALTRY® is not used to treat von Willebrand Disease.
