The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
The study will evaluate the safety and tolerability, optimal biologic dose, and pharmacokinetics of eltrombopag for patients with advanced sarcoma who have a low platelet count and are receiving ADRIAMYCIN and ifosfamide (AI) chemotherapy.

Condition Intervention Phase
Thrombocytopaenia Drug: eltrombopag Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: An Open-label, Dose Ranging Study to Assess the Safety, Efficacy, and Pharmacokinetics of an Oral Thrombopoietin Receptor Agonist (Eltrombopag) Administered to Subjects Receiving Adriamycin and Ifosfamide (AI) Regimen

Primary Outcome Measures:
  • Safety and tolerability endpoints will consist of the evaluation of adverse events (AE), and changes from baseline in vital signs and clinical laboratory parameters [ Time Frame: Approximately 42 weeks ]

Secondary Outcome Measures:
  • OBD will be determined by evaluating platelet count time course data, platelet nadirs, degree and duration of thrombocytopenia, and platelet count recovery from nadir [ Time Frame: Approximately 18 weeks ]
  • Eltrombopag AUC(0-t) [ Time Frame: Approximately 4 weeks ]
  • Doxorubicin and doxorubicinol PK [ Time Frame: Approximately 4 weeks ]

Enrollment: 18
Actual Study Start Date: June 1, 2006
Study Completion Date: October 22, 2010
Primary Completion Date: October 22, 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group B
Group B is a dose escalation phase designed to determine the optimal biological dose of eltrombopag in subjects with sarcoma who received chemotherapy treatment with Adriamycin and Ifosfamide
Drug: eltrombopag
Dosing of sarcoma subjects with eltrombopag after treatment with Adriamycin and Ifosfamide.
Experimental: Group A
Group A will be used for further exploration of the optimal biological dose (as initially established by completion of Group B), by using 2 different dosing schedules of eltrombopag.
Drug: eltrombopag
Dosing of sarcoma subjects with eltrombopag after treatment with Adriamycin and Ifosfamide.
