Macrophage Pharma's Esterase Sensitive Motif (ESM) technology enables delivery of novel, small molecule drug candidates to tumor associated macrophages in a selective manner to reverse immunosuppression established in the tumor microenvironment, and could progress to provide a next-generation immunotherapy with broad utility in oncology.
They discuss general principles of evolution and ecology as they apply to cancer, the molecular mechanisms that underlie genetic heterogeneity within tumors, roles of the microenvironment and spatial heterogeneity within tumors that provide selection pressures and drive the coevolution of cancer cells with their microenvironment, and examples of how to incorporate novel technologies such as liquid biopsy into clinical practice to detect and monitor tumors during treatment.
