Glembatumumab Vedotin in Treating Patients With Recurrent or Refractory Osteosarcoma

• Status: Active, not recruiting
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well glembatumumab vedotin works in treating patients with osteosarcoma that has come back (recurrent) or does not respond to treatment (refractory). Monoclonal antibodies, such as glembatumumab vedotin, may find tumor cells and help kill them.

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

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Antibodies; Antibodies, Monoclonal; Glembatumumab vedotin; Immunoconjugates; Immunotoxins
