VAXIMM is a privately held, clinical stage, Swiss/German biotech company developing oral T-cell immunotherapies for patients suffering from cancer.

VAXIMM’s product platform is based on a live attenuated, safe, orally available bacterial vaccine strain, which is modified to stimulate patients’ cytotoxic T-cells to target specific structures of the tumor and it can be readily adapted to target a wide range of cancer-related antigens.

The Company has a pipeline of complementary development candidates targeting different tumor structures.

Lead product candidate, oral VXM01, activates killer cells targeting tumor-specific vasculature and certain immune-suppressive cells, thereby increasing immune cell infiltration in solid tumors. VXM01 is currently in clinical development for several tumor types, including brain cancer.

VAXIMM has an ongoing clinical trial evaluating VXM01 in combination with the human anti-PD-L1 antibody, avelumab, as part of a scientific collaboration with Merck KGaA, Darmstadt, Germany and Pfizer Inc.

VAXIMM also has a neoantigen program currently in preclinical development; the Company’s platform allows for fast generation and delivery of personalized T-cell cancer vaccines and may overcome key issues faced by other neoantigen approaches. VAXIMM has a strategic clinical trial collaboration with NEC Corporation for the development of personalized neoantigen cancer vaccines.

The Company also has entered into a collaboration agreement with China Medical System Holdings (CMS), granting CMS full rights in China and other Asian countries (excluding Japan) to VAXIMM’s existing programs.

VAXIMM’s investors include BB Biotech Ventures, BioMed Partners, CMS, M Ventures, NEC and Sunstone Capital.

VAXIMM AG is headquartered in Basel, Switzerland.  Its wholly owned subsidiary, VAXIMM GmbH, located in Mannheim, Germany, is responsible for the Company’s development activities.
