Imugene has developed a more potent formulation of its therapeutic cancer vaccine, HER-Vaxx, which will be tested in a Phase Ib/II trial in gastric (stomach) cancer in H215. HER-Vaxx could replicate or improve on the combination of two proven therapeutic antibodies, Herceptin and Perjeta (Roche), which significantly improves survival in breast cancer and may do so in gastric cancer. Imugene aims to gain a major pharma deal following Phase II data in the buoyant cancer immunotherapy area.
