Overview
Brief Summary
This is an open-label, two-arm, Phase I, dose escalation study to evaluate the safety and tolerability and to determine the optimal tolerated regimen(OTR) of pazopanib in combination with gemcitabine (Arm A) or pazopanib, gemcitabine, and cisplatin (Arm B) in patients with advanced solid tumors. Patients will be enrolled in cohorts of 3 to receive escalating doses of pazopanib and gemcitabine or pazopanib, gemcitabine and cisplatin. Dose escalation schemas for each study arm are described in the protocol. For each arm, the OTR will be defined as the highest dose combination of the agents where no more than one out of six patients experiences a dose-limiting toxicity. Six to twelve additional patients in each arm will be studied with the OTR to evaluate toxicity and pharmacokinetics. This will allow an assessment of potential drug-drug interactions. Antitumor activity will be assessed using RECIST criteria.

- •Cardiac angioplasty or stenting; myocardial infarction; unstable angina; symptomatic peripheral vascular disease; Class III or IV congestive heart failure as defined by the New York Heart Association
- •Has had any major surgery, chemotherapy, investigational agent, biological therapy or hormonal therapy within the last 28 days and/or not recovered from a prior therapy.
- •Any unstable or serious concurrent condition (e.g., active infection requiring systemic therapy)
- •Poorly controlled hypertension \[defined as systolic blood pressure (SBP) of greater than or equal to 140mmHg or diastolic blood pressure (DBP) of greater than or equal to 90mmHg\].
- •History of cerebrovascular accident (CVA), pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months.
Arms & Interventions
Arm A
Dose Escalation - Patients will be entered into dose cohorts of three patients. Each cohort will be assigned to a dose level for the duration of the study. There will be no intra-patient dose-escalation. The starting dose will be 400 mg daily of pazopanib, and 1000 mg/m2 gemcitabine. Intermediate dose levels may also be explored. Intravenous gemcitabine will be given on Day 1 and 8 of Cycle 1 and each subsequent cycle. Cohort expansion phase - patients will receive gemcitabine alone, at the OTR dose starting on Day 1 of Cycle 1. Pazopanib will be administered at the OTR beginning on Day 2 Cycle 1 after the last blood sample for gemcitabine analysis is collected, and pazopanib administration will continue for the duration of the study. Patients will return to the clinic on Day 8 of Cycle 1 for simultaneous administration of gemcitabine and pazopanib. On Day 1 of Cycle 2 patients will receive the simultaneous administration of gemcitabine and pazopanib
Intervention: Pazopanib (GW786034)
