A Study of GC33 (RO5137382) in Patients With Advanced or Metastatic Hepatocellular Carcinoma

• Status: Completed
• Trial end date: 2015-08-20
• Target enrollment: 0
• Participant gender: All

Summary

This randomized, placebo-controlled, multicenter study will evaluate the efficacy and safety of GC33 (RO5137382) in previously treated patients with unresectable advanced or metastatic hepatocellular carcinoma. Participants will be stratified according to the level of GPC-3 expression in tumors and randomized to receive either GC33 (1600 mg intravenously) or placebo on Days 1 and 8 of Cycle 1 and every 2 weeks thereafter. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Hoffmann-La Roche
