Pazopanib Hydrochloride and Topotecan Hydrochloride in Treating Patients with Locally Advanced or Metastatic Soft Tissue and Bone Sarcomas That Cannot Be Removed by Surgery

Status: Active

Description

This phase II trial studies how well pazopanib hydrochloride and topotecan hydrochloride work in treating patients with soft tissue and bone sarcomas that have from where it started to nearby tissue or lymph nodes or have spread to other places in the body and cannot be removed by surgery. Pazopanib hydrochloride and topotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Trial Objectives and Outline

PRIMARY OBJECTIVES:

I. To determine progression free rate at week 12 for patients with soft tissue sarcoma (STS) treated with pazopanib hydrochloride (pazopanib) plus oral topotecan hydrochloride (topotecan).

SECONDARY OBJECTIVES:

I. To determine the overall response rate for patients with STS treated with combination pazopanib and topotecan.

II. To determine the clinical benefit rate (complete response [CR] + partial response [PR] + stable disease [SD]) for patients with STS treated with combination pazopanib and topotecan.

III. To determine median progression-free rate (PFR) for patients with STS treated with combination pazopanib and topotecan.

IV. To evaluate overall survival (OS) for patients with STS treated with combination pazopanib and topotecan.

V. To assess safety and tolerability for patients treated with combination pazopanib and topotecan.

VI. To estimate the PFR for patients with osteosarcoma treated with combination pazopanib and topotecan.

VII. To estimate the PFR for patients with liposarcoma treated with combination pazopanib and topotecan.

TERTIARY OBJECTIVES:

I. To estimate the correlation of PFR and OS to levels of soluble (s)VEGFR2 and PIGF.

OUTLINE:

Patients receive pazopanib hydrochloride orally (PO) once daily (QD) on days 1-28 and topotecan hydrochloride PO on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 2 years (patients with progressive disease) or 5 years (patients without progressive disease).
