RRx-001

A new class of anti-cancer therapy with the potential to convert “treatment-resistant” tumors into “treatment sensitive” tumors

EpicentRx’s lead program, RRx-001, is among a portfolio of immunotherapeutic compounds that normalize the tumor microenvironment, activate the tumor associated macrophages (TAMs) of the innate immune system, and sensitize solid tumors to standard therapies in small cell lung cancer, glioblastoma, colorectal cancer and additional cancers.

RRx-001 is a next generation, small molecule anticancer immunotherapeutic that targets the CD47 – SIRPα axis and repolarizes tumor associated macrophages (TAMs) and other immunosuppressive cells in the tumor microenvironment to an immunostimulatory phenotype. RRx-001 is designed to be used either as a monotherapy or in combination with chemotherapy, radiation therapy or immunotherapy. 

RRx-001 is currently in the Phase 3 REPLATINUM trial for the treatment of third-line and beyond small cell lung cancer. RRx-001 has Orphan Drug designation from FDA for SCLC, neuroendocrine cancer and glioblastoma, and from EMA for SCLC, and is on accelerated approval track with FDA for SCLC.
