Sunstone Life Science Fund II portfolio company VAXIMM AG, a Swiss/German biotech company focused on developing oral T-cell immunotherapies, today announced that it has entered into a collaboration agreement with Merck KGaA, Darmstadt, Germany, a leading science and technology company which in the US and Canada operates as EMD Serono, and Pfizer Inc. (NYSE: PFE) to evaluate avelumab*, a human anti-PD-L1 antibody, in combination with VAXIMM’s VXM01. VXM01 is an investigational oral T-cell immunotherapy designed to activate T-cells to attack the tumor vasculature, and, in several tumor types, attack cancer cells directly. Under the terms of the agreement, VAXIMM will be responsible for conducting two open-label Phase I/II trials – one in glioblastoma and one in metastatic colorectal cancer.

* Avelumab is under clinical investigation for treatment of glioblastoma and metastatic colorectal cancer and has not been demonstrated to be safe and effective for these indications. There is no guarantee that avelumab will be approved for glioblastoma and metastatic colorectal cancer by any health authority worldwide.
