A Phase 1b Study of Demcizumab Plus Pembrolizumab in Locally Advanced or Metastatic Solid Tumors

• Status: Completed
• Trial end date: 2017-05-19
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to test the efficacy and safety of an experimental drug, demcizumab, when given in combination with pembrolizumab. Demcizumab is a humanized monoclonal antibody and was developed to target cancer stem cells. Demcizumab may block the growth of cancer stem cells, the remaining cancer cells, and it may also impair the productive growth of new blood vessels, which tumors need to grow and spread.

This study is sponsored by OncoMed Pharmaceuticals, which is referred to as OncoMed or the Sponsor in this consent form.
