A Study of Onartuzumab in Combination With mFOLFOX6 in Participants With Metastatic HER2-Negative and MET-Positive Gastroesophageal Cancer

Completed · Phase 3 · Has a placebo group

Conditions studied: Gastric Cancer

In brief

This randomized, multicenter, double-blind, placebo-controlled study will evaluate the efficacy and safety of onartuzumab (MetMAb) in combination with 5-fluorouracil, folinic Acid, and oxaliplatin (mFOLFOX6) in participants with metastatic human epidermal growth receptor (HER) 2-negative and MET-positive adenocarcinoma of the stomach or gastroesophageal junction. Participants will be randomized in a 1:1 ratio to receive either onartuzumab or placebo in combination with mFOLFOX6. Participants may continue to receive onartuzumab or placebo until disease progression, unacceptable toxicity, participant or physician decision to discontinue treatment.

• Clinically significant gastrointestinal abnormalities, apart from gastric cancer, including uncontrolled inflammatory gastrointestinal diseases
• Significant history of cardiac disease
• Significant vascular disease
• Serious active infection at the time of randomization, or other serious underlying medical conditions that would impair the ability of the participant to receive protocol treatment
• Infection with human immunodeficiency virus, hepatitis B, or hepatitis C
