Details and patient eligibility

About

This study is for patients who have been diagnosed with soft tissue sarcoma that has spread (metastasized) or that is not eligible for removal by surgery. The purpose of this study is to determine how soft tissue sarcomas respond to treatment with an investigational drug called tivozanib. In some lab and clinical studies, tivozanib has been shown to interfere with the growth of some types of tumors. The study will also evaluate how safe the study treatment is by observing how many and what kind of adverse events (side effects) participants experience.

Full description

PRIMARY OBJECTIVES:

I. To determine the progression-free survival (defined as complete response [CR] + partial response [PR] + stable disease [SD]) assessed at 16 weeks for patients treated with tivozanib.

SECONDARY OBJECTIVES:

I. Overall response rate (defined as CR + PR). II. Clinical benefit rate (CR + PR + SD). III. Overall survival (up to 2 years beyond progression). IV. Correlation of clinical outcome with antibodies for vascular endothelial growth factor receptor 1 (VEGFR1) and VEGFR2.

V. Assess Safety and tolerability.

OUTLINE:

Patients receive tivozanib orally (PO) daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity, or until discontinuation per patient preference or physician recommendation.

After completion of study treatment, patients are followed up every 3 months for 2 years.

Inclusion criteria

Patients must have histologically or cytologically confirmed sarcoma of soft tissue
Patients must have metastatic and/or locally advanced or locally recurrent disease
Patients must have measurable disease within 4 weeks prior to registration by RECIST 1.1, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques or as >= 10 mm with spiral computed tomography (CT) scan; tumor lesions that are situated in a previously irradiated area may be considered measurable for the purposes of this study only if there is evidence of growth of the area following a course of irradiation that cannot be attributed to necrosis or bleeding into the tumor
Patients must have had a minimum of 1 and a maximum of 4 prior chemotherapy regimens for recurrent/metastatic disease (it will be up to the treating investigator to define what constitutes a "regimen" in each case); the last dose of systemic therapy (include tyrosine kinase inhibitors) must have been given at least 4 weeks prior to initiation of therapy; patients receiving BCNU or mitomycin C must have received their last dose of such therapy at least 6 weeks prior to initiation of therapy
Patients with brain metastasis that have been treated with definitive surgery or radiation and have been clinically stable for 3 months following the procedure with no neurological signs or symptoms and no requirement for systemic glucocorticoids are eligible for study
Patients must exhibit an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Absolute neutrophil count >= 1.5 x 10^9/l
Platelets >= 75 x 10^9/l
Total bilirubin =< 1.5 x upper limit of normal (ULN) (except for patients with known Gilbert Syndrome)
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional ULN
Serum creatinine =< 1.5 x ULN
If urine protein:creatinine (UPC) >= 1, then a 24-hour urine protein must be assessed; patients must have a 24-hour urine protein value < 1g to be eligible
Patients must not have current evidence of another malignancy; there are no restrictions regarding prior history of malignancy
If female and of childbearing potential, documentation of negative pregnancy test is required within 7 days prior to first dose; sexually active males and females of childbearing potential must agree to use adequate contraceptive measures, while on study and for 30 days after the last dose of study drug; all subjects (and their partners) must agree to use a highly effective method of contraception; effective birth control includes (a) intrauterine device (IUD) plus one barrier method; or (b) 2 barrier methods; effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm)
- Note: oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are not considered effective for this study
Adverse events related to prior tumor-specific therapy must have resolved to less than or equal to National Cancer Institute (NCI) Common Terminology Criteria of Adverse Events (CTCAE) (version 4) grade 1 prior to study entry (except alopecia)
Patients taking cytochrome P450 (CYP)3A4 inducers at the time of screening/registration are still eligible for participation, but whenever possible these medications should be discontinued or changed to one that is not an inducer
- NOTE: No washout period is required
- NOTE: It will be up to the treating investigator's discretion to assess whether or not the risk of discontinuing or changing the medication is higher or lower than the risk of continuing it while on study for the individual patient
Patients must have the ability to understand and the willingness to sign a written informed consent document; signed and dated informed consent must be obtained prior to registration on trial

Exclusion criteria

Patients with any one of the following sarcoma histological subtypes will not be eligible for participation: alveolar soft-part sarcoma, chondrosarcoma, dermatofibrosarcoma, Ewing sarcoma, gastrointestinal stromal tumor (GIST), Kaposi sarcoma, mixed mesodermal tumor/carcinosarcoma, osteosarcoma, and low grade (grade 1) sarcomas; NOTE: Myxoid liposarcoma with t(12;16) or t(22;22) is permitted; rhabdomyosarcoma (Embryonal, Alveolar, pleomorphic), interdigitating dendritic sarcoma, giant cell tumor of bone
