Study Endpoints
Primary Endpoints
Determine if the Treatment of AMG 479 at 12 mg/kg and/or 20 mg/kg in Combination With Gemcitabine Improves Overall Survival as Compared With Placebo in Combination With Gemcitabine in Subjects With Metastatic Adenocarcinoma of the Pancreas
From randomization up to 20 months

The primary endpoint of the study was OS, defined as the time from randomization to death.

Number of Participants With Dose Limiting Toxicities (DLTs; Phase 1b Portion Only)

Phase 1b AMG 655 3mg/kgEXPERIMENTALSubjects were treated with one of 2 dose levels of AMG 655 (3 mg/kg) with gemcitabine.
Phase 1b AMG 655 10mg/kgEXPERIMENTALSubjects were treated with one of 2 dose levels of AMG 655 (10 mg/kg) with gemcitabine.
Phase 2 AMG 655EXPERIMENTALSubjects were treated with the dose of AMG 655 (10mg/kg) in combination with gemcitabine. Gemcitabine (1000 mg/m2) was administered by intravenous infusion on days 1, 8 and 15 of each 28 day cycle followed by the AMG 655 infusion on days 1 and 15 after completion of the gemcitabine infusion.

Gemcitabine (1000 mg/m2) was administered by intravenous infusion on days 1, 8 and 15 of each 28 day cycle followed by the AMG 479 infusion on days 1 and 15 after completion of the gemcitabine infusion.
Phase 2 AMG 655-placeboPLACEBO_COMPARATORSubjects were treated with the dose of AMG 655-placebo in combination with gemcitabine. Gemcitabine (1000 mg/m2) was administered by intravenous infusion on days 1, 8 and 15 of each 28 day cycle followed by the AMG 655-placebo infusion on days 1 and 15 after completion of the gemcitabine infusion.
