Research Associate, Quantitative Biology (Job Code #RAQBAB)

FLX Bio, Inc. is an immuno-oncology company focused on the discovery and development of orally-available, small molecule drugs to activate the immune system and eradicate cancer. Using its integrated immuno-oncology drug discovery platform, FLX Bio’s small molecule compounds specifically target proteins and pathways important for regulatory T cells or myeloid cells within the tumor microenvironment. Its lead candidate FLX475, a best-in-class CCR4 inhibitor, entered Phase 1 studies in December 2017 and has the potential to be used alone or in combination with checkpoint inhibitors to treat a variety of cancers. The company employs a precision medicine strategy for prospective patient selection in clinical studies, applying its robust computational and translational biology capabilities to identify key biomarkers that should maximize clinical response and increase the probability of clinical success. In addition, FLX is developing small molecule inhibitors of GCN2, a stress response kinase that detects amino acid starvation in the tumor microenvironment, and USP7, a therapeutic target involved in multiple cancer pathways.
