- Additional risk factors for torsades de pointes including heart failure (subjects
that have functional class III or IV congestive heart failure), hypokalemia,

Descriptive Information
Brief Title  ICMJE Study Evaluating The Effects Of Oprelvekin On Cardiac Repolarization In Subjects With Chemotherapy Induced Thrombocytopenia
Official Title  ICMJE Study Of The Effects Of Oprelvekin On Cardiac Repolarization In Subjects At Risk Of Severe Thrombocytopenia After Myelosuppressive Chemotherapy
Brief SummaryThis is an open-label study in which oprelvekin will be administered for the prevention of severe low blood platelet cell counts (cells in your blood that keep bleeding and clotting stable) in adults with cancer who are taking chemotherapy (anti-cancer drug) that has a side effect of blocking your bone marrow from making platelet cells. The purpose of this study is to learn more about the effects of the recommended dose of oprelvekin on the heart's electrical cycle.
