Brief summary:
The purpose of this study is to compare the overall survival in patients with previously untreated metastatic pancreatic cancer receiving gemcitabine/nab-paclitaxel plus OGX-427 or gemcitabine/nab-paclitaxel plus placebo.

Detailed description:
Patients with pancreatic cancer usually present with inoperable disease and systemic therapy becomes the primary form of treatment. The combination of gemcitabine plus nab-paclitaxel represents an appropriate front-line standard of care for patients with metastatic pancreatic cancer. However, poor outcomes with this disease warrant exploration of novel drugs with unique mechanisms of action. Preclinical evidence suggests that OGX-427 has shown promising activity in pancreatic cancer. In this trial, we will compare the overall survival of patients with previously untreated metastatic pancreatic cancer using OGX-427 with either gemcitabine/nab-paclitaxel or a placebo with gemcitabine/nab-paclitaxel.

Arms:
arm 1: Three loading doses of OGX-427 at 600mg IV will be administered Days -9 to -1. Following the loading dose period, OGX-427 will be administered at 600mg IV weekly Days 1, 8, 15, and 22 of each 28 day cycle during the Treatment Phase. arm 2: Three loading doses of placebo will be administered Days -9 to -1. Following the loading dose period, placebo will be administered weekly Days 1, 8, 15, and 22 of each 28 day cycle.

Interventions: intervention 1: OGX-427 intervention 2: Placebo
Intervention descriptions: intervention 1: Three separate administrations of OGX-427 will be given during the 9-day Loading Dose Period. Following the Loading Dose Period, patients will receive 600mg OGX-427 prior to the administration of nab-paclitaxel (125mg/m2 IV)and gemcitabine (1000mg/m2 IV)administration on Day 1, 8, and 15 of each cycle. OGX-427 will also be administered on Day 22 during each cycle (i.e., weekly). Patients will continue 28 day treatment cycles until disease progression or until other reasons for discontinuation from treatment. intervention 2: Three separate administrations of Placebo will be given during the 9-day Loading Dose Period. Following the Loading Dose Period, patients will receive placebo prior to the administration of nab-paclitaxel (125mg/m2 IV)and gemcitabine (1000mg/m2 IV)administration on Day 1, 8, and 15 of each cycle. Placebo will also be administered on Day 22 during each cycle (i.e., weekly). Patients will continue 28 day treatment cycles until disease progression or until other reasons for discontinuation from treatment.
