Treatment options can vary largely based on each patient. The majority of doctor’s not familiar with GT will suggest platelet transfusions for most major bleeds. We recommend you do this as a LAST resort due to the risk of your body producing antibodies. Platelets should always be your last trick in the bag.

If platelets are needed, HLA matched platelets are the best way to ensure the risk of antibodies is as low as possible.

Another treatment option is using NovoSeven to help with blood coagulation in both patients with antibodies and without. It is important to note that this should be the first method to try and stop major bleeds. Dosage and infusion times will vary based on the patient.

Funding is of the utmost importance in this final stretch towards human trials.
