Randomized Double-blind Placebo-controlled Trial of Primary Prophylaxis With Recombinant Human Thrombopoietin Administered to Patients With High Risk Sarcoma Receiving Intensive Chemotherapy
Intensive chemotherapy is often associated with low platelet counts often requiring platelet
transfusions to maintain platelet counts. In previous clinical studies administration of
rhTPO has been demonstrated to increase platelet counts.

To evaluate the effectiveness of intravenous rhTPO vs. placebo as primary prophylaxis in
reducing the cumulative proportion of patients requiring platelet transfusion for severe
chemotherapy-induced thrombocytopenia (platelet count <15,000) during the first four study
cycles. To evaluate the severity and duration of thrombocytopenia and neutropenia associated
with rhTPO prophylaxis, the impact of rhTPO prophylaxis on health economics/cost
effectiveness, and patient quality of life. To assess the safety of multiple IV doses of
rhTPO.
