Conditions: Metastatic or Locally Advanced Unresectable Pancreatic Adenocarcinoma
Keywords: TH-302 Evofosfamide Pancreatic Cancer EMR200592-001
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 693
Healthy volunteers: no

Brief summary:
This Phase 3 trial is a randomized, double-blind, placebo-controlled trial of gemcitabine in combination with TH-302 compared to gemcitabine in combination with placebo in subjects with locally advanced unresectable or metastatic pancreatic adenocarcinoma. Randomized subjects will receive TH-302 plus gemcitabine or gemcitabine plus placebo in 4-week cycles until there is evidence of progressive disease, intolerable toxicity, or the subject discontinues from the trial for other reasons (for example, withdrawal of consent). The primary efficacy endpoint is overall survival (OS) time. The data cut-off for statistical analyses of the primary and secondary endpoints will be reached when 508 events (deaths) will be reported. No planned interim analyses will be conducted. An Independent Safety Monitoring Board (ISMB) will provide periodic evaluations of the unblinded safety data to ensure subject safety and the validity and scientific merit of the study. A total of 660 subjects will be enrolled.

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: TH-302 intervention 2: Gemcitabine intervention 3: Placebo (5 percent dextrose - D5W)
Intervention descriptions: intervention 1: TH-302 will be administered at a dose of 340 milligrams per square meter (mg/m\^2) as intravenous infusion over 30 minutes on Day 1, 8 and 15 of every 28-day cycle. Doses will be administered until evidence of progressive disease, intolerable toxicity or subject withdrawal. intervention 2: Gemcitabine will be administered at a dose of 1000 (mg/m\^2) as intravenous infusion over 30 minutes on Day 1, 8 and 15 of every 28-day cycle. Doses will be administered until evidence of progressive disease, intolerable toxicity or subject withdrawal. intervention 3: TH-302 placebo (5 percent dextrose - D5W) will be administered as intravenous infusion over 30 minutes on Day 1, 8 and 15 of every 28-day cycle. Doses will be administered until evidence of progressive disease, intolerable toxicity or subject withdrawal.
