Brief summary

Intensive chemotherapy is associated with significant thrombocytopenia, often requiring platelet transfusion to maintain platelet counts. This investigational drug has demonstrated the ability to increase platelet counts. This study will test the safety and efficacy of an investigational drug in the prevention of thrombocytopenia in patients with high-risk sarcoma receiving AI (Adriamycin/Ifosfamide) chemotherapy.

Design outcomes

Primary

MeasureTime frame
To evaluate the effectiveness of intravenous rhTPO versus placebo in reducing the cumulative proportion of patients who experience severe chemotherapy induced thrombocytopenia.

Secondary

MeasureTime frame
Evaluate the severity and duration of thrombocytopenia and neutropenia associated with rhTPO prophylaxis.
Quantify the effect of rhTPO on the occurrence of any bleeding events associated with thrombocytopenia.
Assess the likelihood that patients were to have adequate hematological recovery to allow on-time chemotherapy administration in the subsequent cycles.
Assess the safety of multiple IV doses of rhTPO.
Identify the effect of rhTPO on the number of platelet transfusions.
Assess the antitumor activity of AI chemotherapy.
Evaluate the impact of rhTPO prophylaxis on patient quality of life.
Evaluate the impact of rhTPO prophylaxis on health economics/cost effectiveness.
Determine serum concentrations of TPO in the context of rhTPO and chemotherapy administration
Determine the occurrence and clinical implications of any anti-TPO antibodies.
