Study Description

Brief Summary

This study is a phase 2, randomized, double-blind, placebo controlled, multi-center study to estimate the improvement in PFS (compared to control subjects) and evaluate the safety and tolerability of AMG 386 in combination with paclitaxel in the treatment of subjects with advanced recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer.

Primary Outcome Measure:

• Progression free survival (PFS)

Secondary Outcome Measures:

Object Response Rate (ORR), duration of response (DOR). CA-125 response rate
Safety and Tolerability
Change and duration of change on blood levels of CA-125

Condition or Disease	Intervention/Treatment	Phase
Ovarian Cancer Fallopian Tube Cancer Primary Peritoneal Cancer	Drug: AMG 386 Drug: AMG 386 Drug: Paclitaxel Drug: AMG 386 Placebo	Phase 2

Detailed Description

Primary Objective:

To estimate the treatment effect as measured by progression free survival (PFS) of subjects with recurrent ovarian cancer receiving AMG 386 (either 3 mg/kg or 10 mg/kg IV QW) in combination with paclitaxel (80 mg/m2 IV QW; 3 on/1 off)compared to subjects receiving paclitaxel (80 mg/m2 IV QW; 3 on/1 off) plus placebo

Secondary Objective(s):

To evaluate the safety and tolerability of the combination regimen of AMG 386/paclitaxel
To estimate other measures of treatment effect (by parameters other than PFS) of subjects receiving AMG 386 in combination with paclitaxel compared to subjects receiving paclitaxel plus placebo
To evaluate the AMG 386 pharmacokinetics parameters (Cmax and Cmin ) when administered with paclitaxel in subjects with recurrent ovarian cancer
To estimate the incidence of occurrence of anti-AMG 386 antibody formation
To estimate the change and duration of change on blood levels of CA-125
To evaluate the clinical benefit among subjects receiving AMG 386 10 mg/kg monotherapy after disease progression on paclitaxel
To estimate the impact of AMG 386 on patient reported ovarian cancer specific symptoms and HRQoL using the FACT-O, the FACT-O ovarian cancer subscale (OCS), and the FACT-O 3-item (O1, O2, O3) cancer symptom specific subscale (OCS 3-item subscale)

Exploratory Objective(s):

To explore the associations between progression free survival, objective response, CA-125, and continuous measures of tumor burden (the percentage change from baseline in the sum of the longest diameters of target lesions)
To explore the pharmacodynamic (PD) response as assessed by changes in blood levels of angiogenic cytokines, tumor apoptosis, CA-125 and other markers
To investigate the effects of genetic variation in drug metabolism, cancer genes and drug target genes on ovarian cancer and subject response to investigational product (separate informed consent)
To explore the impact of AMG 386 on patient reported overall health status as measured by the EuroQoL (EQ-5D)

Hypothesis:

This study will provide an estimate and corresponding 2-sided 80% confidence interval with an approximate maximum half-width of 0.22 of the efficacy, as measured by the PFS hazard ratio of AMG 386 in combination with paclitaxel versus paclitaxel alone for 2 pooled dose groups of AMG 386 (10 mg/kg QW and 3 mg/kg QW) in combination with paclitaxel versus the paclitaxel plus placebo group.
