Hematologic Malignancy Clinical Trial
— CoVeRTS-HMOfficial title:
Cold Versus Room Temperature Storage of Platelets for Bleeding in Hematologic Malignancy - a Pilot Trial
This is a pilot trial to discover the feasibility of recruiting 50 pts over the course of 12 months. The trial is testing the efficacy of using cold-stored vs. room temperature stored (current standard of care) platelets to treat bleeding in persons with hematological disorders and thrombocytopenia.
