Abagovomab stimulates the humoral immune response and the cell-mediated immune response in the studies conducted to date. In the proof of concept (POC) study abagovomab prolonged overall survival in those OC recurrent patients who showed an immune response. Abagovomab has an excellent safety and tolerability profile. These characteristics make abagovomab an optimal candidate for a maintenance treatment for OC patients after frontline therapy. The final results of the Phase II/III pivotal study evaluating abagovomab in this setting will be available in the first half of 2011.
