OncoMed presents data from Phase 1b clinical trial of demcizumab OncoMed presented data from its ongoing Phase 1b clinical trial of demcizumab in first-line Stage IV pancreatic cancer patients. Demcizumab was generally well tolerated in combination with both gemcitabine and Abraxane with fatigue, hypertension, nausea and vomiting being the most common drug-related toxicities. No demcizumab-related reversible cardiotoxicity events have occurred with the implementation of regular monitoring, a truncated treatment approach and cardioprotective medication, if indicated. The combination of gemcitabine with or without Abraxane did not appear to influence the pharmacokinetics of demcizumab. 50% evaluable patients who received the demcizumab/gemcitabine/Abraxane combination had partial responses as measured by RECIST and two patients had stable disease resulting in a clinical benefit rate of 83%. A randomized Phase 2 clinical trial in patients with first-line pancreatic cancer is planned for the second half of 2014.
