SOUTH SAN FRANCISCO, Calif., March 31, 2017 (GLOBE NEWSWIRE) -- FLX Bio, Inc., a biopharmaceutical company focused on the discovery and development of novel immuno-oncology (IO) agents and molecularly-targeted therapies, announced today that it will present a poster with preclinical data for its C-C Chemokine Receptor 4 (CCR4) antagonist compounds, at the American Association of Cancer Research (AACR) Conference to be held April 1-5, 2017, in Washington, D.C.
CCR4 is a non-redundant mechanism for selectively recruiting regulatory T cells (Treg) to the tumor microenvironment. Treg dampen anti-tumor immune responses and worsen outcomes by suppressing effector T cells and dendritic cells. FLX Bio has developed best-in-class, orally-administered potent and selective CCR4 antagonists that reduce tumor Treg and inhibit tumor growth in murine models when combined with other IO agents. In contrast to the non-selective approach using anti-CCR4 depleting antibodies, FLX Bio’s CCR4 antagonists reduce Treg in the tumor, but not in peripheral tissues and represent a potentially safer approach. FLX Bio’s CCR4 antagonists are currently in preclinical development, and its lead CCR4 antagonist compound is expected to enter the clinic in 2017.
Alexander Rudensky, Chairman of FLX Bio’s Scientific Advisory Board and Chair of the Immunology Program at the Sloan Kettering Institute, Director of the Ludwig Center for Cancer Immunotherapy at Memorial Sloan Kettering Cancer Center and Member, National Academy of Sciences said, “CCR4 is a highly promising target to selectively block Treg recruitment into the tumor microenvironment. FLX Bio has developed a novel series of small molecule CCR4 antagonists that have demonstrated excellent preclinical efficacy data, with potentially broad utility in combination with checkpoint inhibitors, immune agonists, CAR-T and cancer vaccine approaches.”
Title: Potent and selective C-C chemokine receptor (CCR4) antagonists potentiate anti-tumor responses by inhibitory regulatory T cells (Treg)
