Study Endpoints
Primary Endpoints
The primary objective is to identify the incidence of adverse events and clinical laboratory abnormalities defined as dose limiting toxicity in subjects treated with AMG 386 + pegylated liposomal doxorubicin (cohort A) and with AMG 386 + topotecan
first 4 weeks of treatment
Secondary Endpoints
To evaluate the treatment effect as measured by: objective response rate (ORR), duration of response (DOR), PFS, change in tumor burden, CA 125 Response and Progression by GCIG and CA-125 duration of response
Treatment and follow-up phase of study
To evaluate the incidence of adverse events and clinical laboratory abnormalities not defined as DLTs.
first 4 weeks of treatment
To determine the pharmacokinetics of pegylated liposomal doxorubicin (and its metabolite, doxorubicinol), topotecan and AMG 386 (Cmax, AUC, and Cmin for intensive assessment; Cmax and Cmin for sparse assessment).

ArmTypeDescription
Part 1EXPERIMENTALIn part 1, six subjects will be assigned to each cohort A or B. This is a dose escalation/de escalation study with a 6 + 3 design based on the incidence of DLTs (dose limiting toxicities) during the first 4 weeks of combined therapy \[(cohort A: AMG 386 and pegylated liposomal doxorubicin) or (cohort B: AMG 386 and topotecan)\].
Part 2EXPERIMENTALThe decision on declaration of a safe and tolerable dose during part 1 will lead to part 2 (cohort A: liposomal doxorubicin + AMG 386 MTD (max tolerated dose) of part 1, cohort B: Topotecan + AMG 386 MTD (max tolerated dose) of part 1
