Pazopanib/Doxil in Adv Relapsed Plat Sensitive or Resistant Ovarian, Fallopian or Primary Peritoneal Adenocarcinoma

A Phase I/II Study of the Combination of Pazopanib and Liposomal Doxorubicin (Doxil) in Patients With Advanced Relapsed Platinum-Sensitive or Platinum-Resistant Ovarian, Fallopian Tube or Primary Peritoneal Adenocarcinoma

In this study, patients with relapsed or refractory ovarian cancer will receive treatment with pazopanib and liposomal doxorubicin (Doxil) until disease progression or unacceptable toxicity occurs. The Phase I portion will define the dose limiting toxicity (DLT) of pazopanib and liposomal doxorubicin when administered in combination. Once the maximum tolerated dose has been identified in the Phase I portion, the Phase II portion will evaluate efficacy and safety of this combination in the same patient population.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase I: Maximum Tolerated Dose (MTD) of Pazopanib and Liposomal Doxorubicin	The MTD of the drug combination will be determined as the highest dose at which ≤1 of 6 subjects experiences a Grade 3 or Grade 4 DLT according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.0.	18 months
Phase I - Dose Limiting Toxicities	As requested, this outcome measure reports the number of patients experiencing dose limiting toxicities (DLTs) in the Phase I portion of the study	18 months
Phase II: Progression Free Survival	Defined as from date of randomization until objective tumor progression or death. Response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) and CA-125 response in patients using the Rustin Criteria.	18 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase II - Overall Survival of Patients With Relapsed/Refractory Ovarian Cancer Following Treatment With Pazopanib and Liposomal Doxorubicin		18 months
Response Rate in the Subsets of Patients With Platinum-sensitive and Platinum-refractory Ovarian Carcinoma	The response rate in the subsets of patients with platinum-sensitive and platinum-refractory ovarian carcinoma is evaluated as a measure of efficacy of pazopanib/liposomal doxorubicin. Response rate ( Percentage of patients whose disease decreased (Partial response - PR) and/or disappears (Complete response - CR) after treatment) was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) and CA-125 response in patients using the Rustin Criteria. CR: disappearance of all target and nontarget lesions and no evidence of new lesions documented by two disease assessments at least 4 weeks apart. Normalization of CA125, if elevated at baseline, is required for ovarian carcinoma studies. PR is >= 30% decrease in the sum of longest diameter(LD) of all target measurable lesions taking as reference the baseline sum of LD. There can be no unequivocal progression of nontarget lesions and no new lesions.	18 months
Number of Participants Experiencing Adverse Events With the Combination of Pazopanib and Liposomal Doxorubicin Doses	An adverse event (AE) is the development of an undesirable medical condition, or the deterioration of a pre-existing medical condition (other than the condition that is being treated by the trial) following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. The number of participants experiencing such adverse events that are possibly/probably/definitely related to the study drugs are reported here.	18 months
