Details and patient eligibility

About

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.

Full description

This is an open label single site Phase II clinical trial to identify a potentially promising therapy dose for Sunitinib malate, an oral multi-kinase inhibitor. 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 which in the opinion of the treating physician or the trial Principal Investigator (PI) compromises the ability of the patient to receive treatment or the patient desires to stop treatment.

All patients with unresectable or metastatic STS: leiomyosarcoma, liposarcoma, fibrosarcoma, and MFH seen at the Moffitt Cancer Center will be screened for eligibility to be enrolled in the study.

An office visit will be required before the beginning of every cycle every 6 weeks to assess toxicity and for physical examination. Complete blood count (CBC) and differential, comprehensive metabolic panel, and electrocardiogram (ECG) will be obtained at every scheduled visit.
