Phase II Study of Sunitinib Malate for Metastatic and/or Surgically Unresectable Soft Tissue Sarcoma

• Status: Completed
• Trial end date: 2011-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This is an open label single site Phase II clinical trial to identify a potentially promising therapy dose for Sunitinib malate. The study drug will be taken orally once daily on days 1 through 28 of each 42 day cycle. Treatment will be continued until there is either disease progression or cumulative/acute toxicity.

All patients with unresectable or metastatic soft tissue sarcoma (STS): leiomyosarcoma, liposarcoma, fibrosarcoma, and malignant fibrous histiocytoma (MFH) seen at the Moffitt Cancer Center will be screened for eligibility to be enrolled in the study.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: H. Lee Moffitt Cancer Center and Research Institute
• Collaborator: Pfizer
• Treatments: Sunitinib

• Any of the following within the 6 months prior to study drug administration:

• myocardial infarction,

• severe/unstable angina,

• coronary/peripheral artery bypass graft,

• symptomatic congestive heart failure,

• cerebrovascular accident or transient ischemic attack, or pulmonary embolism

• Ongoing cardiac dysrhythmias of NCI CTCAE greater than or equal to grade 2

• Prolonged QTc interval on baseline electrocardiogram (ECG) > 500 msec.
