A BETTER WAY TO MAKE ANTIBODIES TO TREAT CANCER? In a facility: Using B-cells in your body VS B-cells are cells in the human body that naturally produce millions of antibodies For example, Merck s PD-1 inhibitor Keytruda Teaching B-cells to make antibodies using peptide antigens 7

WHY SELECT AND TARGET PD-1 FOR B-CELL VACCINATION? Monoclonal antibody immunotherapies Keytruda (Merck) and Opdio (BMS) targeting PD-1 sold USD$3.8B and $4.9B, respectiely, in 2017. In industry-recognized mouse cancer models (colon cancer), the PD-1 targeting B-cell accine is more superior than the gold standard mouse PD-1 monoclonal antibody (used in preclinical model testing for Keytruda and Opdio). Whilst acknowledging the rapid rise in clinical trials inoling PD-1 and their combination with other treatments *, a PD-1 B-cell accination approach represents a paradigm shift in cancer immunotherapy. * Tang etal. Comprehensie analysis of the clinical immuno-oncology landscape, Annals of Oncology, 2017. The combination of the PD-1 accine with the acquired Phase II Her-2 accine significantly inhibits tumor growth c/w mab control in a Her-2+ model of colon cancer. 14
