This study tests whether a daily pill called mitapivat can reduce the number of blood transfusions you need. It is for people with sickle cell disease who have had at least one transfusion in the past year and are not on regular transfusion therapy.
Indianapolis, IndianaAges 12 years+ - NCT05874843Recruiting
Testing a bedside blood clot test in children
This trial checks whether a bedside machine (TEG 6s) can measure blood clotting in children during planned surgery. It may help doctors get faster, more accurate information about clotting during the operation.
