A Study of Gemcitabine and Demcizumab (OMP-21M18) With or Without Abraxane® as 1st-line Treatment in Subjects With Locally Advanced or Metastatic Pancreatic Cancer

Summary

The purpose of this study is to test the safety and determine the optimal dose of a new experimental drug, demcizumab (OMP-21M18), when given in combination with gemcitabine with or without (+/-) Abraxane®. Historically, single agent gemcitabine has been the standard treatment for pancreatic cancer. However, recent data suggests that gemcitabine plus Abraxane® may be superior to gemcitabine alone, thus this combination is emerging as the new standard therapy for pancreatic cancer. However, Abraxane® has not been approved for the treatment of pancreatic cancer at this time. Demcizumab is a humanized monoclonal antibody and was developed to target cancer stem cells. This study is sponsored by OncoMed Pharmaceuticals, which is referred to as OncoMed or the Sponsor in this consent form. The study is designed to test the safety of demcizumab at different dose levels when given with gemcitabine +/- Abraxane® and the effects, both good and bad, that it has on participants. Demcizumab may block the growth of cancer stem cells, the remaining tumor cells, and it may also prevent the growth of new blood vessels that tumors need to grow and spread. Although demcizumab has been administered with gemcitabine to cancer patients, it has not been given in combination with gemcitabine and Abraxane®; thus, it is not known if it will provide any benefit to participants and may cause harmful side effects.
