Healthy volunteers: no

Brief summary:
This study will assess the safety and efficacy of GPX-150 administered intravenously every 3 weeks in the treatment of patients with soft tissue sarcoma.

Detailed description:
This is an open-label, single arm study of GPX-150 in patients with soft tissue sarcoma. Approximately 22 patients will be treated in this study. The population for this study is adult patients with histologically proven advanced and/or metastatic malignant soft tissue sarcoma of intermediate or high histologic grade.

All patients who meet all entry criteria will receive GPX-150 at a starting dose of 265 mg/m2 every 21 days for 16 cycles or until death, disease progression, or unacceptable toxicity or subject withdrawal.

Prior to initiation of treatment, subjects will undergo screening and baseline evaluations. During all study visits, subjects will be evaluated for safety. The dose of GPX-150 may be reduced when subjects meet specified dose reduction safety criteria. Subjects will be evaluated regularly for safety and tolerability. Tumor measurements will be calculated at baseline (within 28 days prior to treatment initiation), then at regular intervals while receiving treatment for up to 1 year. After discontinuing the treatment phase of the study, safety assessments and tumor measurements will be performed 3 weeks after the last dose of study drug.

Arms:
arm 1: GPX-150 for Injection, 265 mg/m2, every 21 days for 16 cycles or until death, disease progression, or unacceptable toxicity, or subject withdrawal.

Interventions: intervention 1: GPX-150 for Injection
Intervention descriptions: intervention 1: GPX-150 at a starting dose of 265 mg/m2 every 21 days for 16 cycles or until death, disease progression, or unacceptable toxicity. The dose of GPX-150 may be reduced by 25% if any dose reduction criteria are met. Two reductions are allowed per subject during the course of the study.
