Brief Summary

This is an open-label, four-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 epirubicin or doxorubicin in patients with advanced solid tumors. Patients will be enrolled in cohorts of 3 to receive escalating doses of pazopanib and epirubicin or doxorubicin. 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. 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.

Outcome Measures

Primary Outcomes (1)

• Optimum tolerated regimen (OTR) for each combination regimen in each arm of the study.OTR determined by evaluation of AEs and change in lab values.OTR defined as highest dosing regimen that results in dose limiting toxicity in no more than 1 of 6 subject

  Subjects will continue on the study until disease progression occurs or one of the discontinuation criteria is met up to approximately 48 months.

Secondary Outcomes (8)

• Safety assessments, including routine physical exam findings, vital signs, clinical laboratory tests (chemistry and hematology to include coagulation factors), clinical monitoring and/or observation, and adverse event reporting.

  Safety assessment timing is noted on the Time and Events Table. Subjects will continue on the study until disease progression occurs or one of the discontinuation criteria is met up to approximately 48 months.

• Safety and tolerability endpoints will include cardiac function (left ventricular ejection fraction) monitored by either MUGA or ECHO. A 12-lead ECG will also be monitored.

  Safety assessment timing is noted on the Time and Events Table. Subjects will continue on the study until disease progression occurs or one of the discontinuation criteria is met up to approximately 48 months.

• Pharmacokinetic endpoints will be AUC, Cmax, Tmax, and t1/2 of pazopanib, epirubicin, and doxorubicin, and clearance of epirubicin and doxorubicin if data are sufficient.

  PK samples will only be collected in Cycle 1 and Cycle 2. Subjects will continue on the study until disease progression occurs or one of the discontinuation criteria is met up to approximately 48 months.

• Assessment of anti-tumor activity using RECIST criteria will be recorded as complete response, partial response, stable disease, or progressive disease.

  Subjects will continue on the study until disease progression occurs or one of the discontinuation criteria is met up to approximately 48 months.

• Levels of circulating cytokine and angiogenic factors (CAF) biomarkers (such as IL 2, IL-10, VEGF, sVEGFR2) in plasma will be determined.

  Biomarker samples will only be collected in Cycles 1, 2, and 3. Subjects will continue on the study until disease progression occurs or one of the discontinuation criteria is met up to approximately 48 months.
