Combination versus Bispecific treatment: Influence of receptor density on target and decoy binding. A. Simulation of total concentration bound at tumor cells in a decoy cell scenario with decoy-target cell ratio of 1; B. Simulation of IGF1R concentration bound at decoy cells (decoy-target cell ratio of 1). Simulations were performed with a fold10- lower receptor density for IGF1R compared to EGFR on tumor cells, which resembles BxPC-3 cells. The receptor density on the decoy cells was assumed to be 2-fold higher than the EGFR receptor density on tumor cells which resembles the difference between tumor cells (BxPC-3) and decoy cells (NIH3T3).
