Primary Outcomes

Measure
12-week Progression Free Rate
time frame: Assessed after 12 weeks of study treatment

Secondary Outcomes

Measure
Progression free survival (PFS)
time frame: Cycle 1 Day 1 until the subject experiences disease progression
Response rate (RR)
time frame: Cycle 1 Day 1 until end of study treatment
Duration of response
time frame: Measure of the amount of time that the criteria for response per RECIST are first met until disease progression
Overall survival (OS)
time frame: Cycle 1 Day 1 up to 24 months after the end of study treatment

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Written informed consent. - Age > or = to 18 years. - Histologically or cytologically confirmed high- or intermediate-grade liposarcoma (allowed subtypes include liposarcoma dedifferentiated, myxoid/round cell, pleomorphic, mixed-type, or not otherwise specified). - Surgically unresectable or metastatic disease. - Any number of prior treatment treatment regimens, including treatment naive subjects. - Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. - Measurable or evaluable (non-measurable) disease per RECIST guidelines version 1.1. Subjects must have documented disease progression within the past 6 months. - Adequate organ system function determined within 14 days prior to first dose of study treatment. - Left ventricular ejection fraction (LVEF) > 50% of the institutional LLN within 28 days prior to the first dose of study treatment. - Females must be of either non-child bearing potential or have a negative pregnancy test within 7 days prior to the first dose of study treatment. Exclusion Criteria: - Well differentiated liposarcoma. - Prior treatment with tyrosine kinase inhibitors (TKIs) or vascular endothelial growth factor (VEGF) inhibitors. - Prior malignancy (Note: subjects who have had another malignancy and have been disease-free for 3 years, or subjects with a history of completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma are eligible). - History or clinical evidence of central nervous system metastases or leptomeningeal carcinomatosis, unless previously treated, asymptomatic, and off steroids and anti-seizure medication for 6 months prior to first dose of study drug - Clinically significant gastrointestinal (GI) abnormalities that may increase the risk for GI bleeding. - Clinically significant GI abnormalities that may affect absorption of investigational product. - Presence of uncontrolled infection. - Corrected QT interval > 480 msecs using Bazett's formula. - History of certain cardiovascular conditions within the past 6 months. - Poorly controlled hypertension [defined as systolic blood pressure of > or = 140 mmHg or diastolic blood pressure > or = 90 mmHg]. - History of cerebrovascular accident including transient ischemic attack, pulmonary embolism, or untreated deep vein thrombosis within the past 6 months. - Prior major surgery or trauma within 28 days prior to the first dose of study drug and/or presence of any non-healing wound, fracture, or ulcer. - Evidence of active bleeding or bleeding diathesis. - Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels that increase the risk of pulmonary hemorrhage. - Hemoptysis in excess of 2.5 mL within 8 weeks of first dose of study drug. - Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent, or compliance to study procedures. - Unable or unwilling to discontinue use of prohibited medications for at least 14 days or five half-lives of a drug, whichever is longer, prior to the first dose of study drug and for the duration of study treatment. - Radiation therapy, minor surgery, tumor embolization, chemotherapy, immunotherapy, biologic therapy, investigational therapy, or hormonal therapy within 14 days or five half-lives of a drug (whichever is longer) prior to the first dose of study drug. - Administration of any non-oncologic investigational drug within 30 days or five half-lives (whichever is longer) prior to receiving the first dose of study drug. - Any ongoing toxicity from prior anti-cancer therapy that is > Grade 1 and/or that is progressing in severity, except alopecia. - Known immediate or delayed hypersensitivity reaction to idiosyncrasy to drugs chemically realted to pazopanib or excipients that contraindicates participation.
