About Replimune

Replimune Group, Inc., headquartered in Woburn, MA, was founded in 2015 with the mission to transform cancer treatment by pioneering the development of novel oncolytic immunotherapies, including the Company’s first commercially available product TUDRIQEVTM (vusolimogene oderparepvec-wtpg), approved under accelerated approval by the U.S. Food and Drug Administration in combination with nivolumab for the treatment of adults with advanced melanoma who experienced disease progression on a PD-1 antibody-based regimen. Replimune’s proprietary RPx platform is based on a potent HSV-1 backbone intended to maximize immunogenic cell death and induce a systemic anti-tumor immune response. Upon intratumor injection, RPx causes direct selective virus-mediated killing of the tumor resulting in the release of tumor derived antigens, alteration of the tumor microenvironment, and when dosed in combination with an immune checkpoint inhibitor immunotherapy, it may ignite a systemic anti-tumor response. The RPx product candidates are expected to be synergistic with most established and experimental cancer treatment modalities, leading to the versatility to be developed alone or combined with a variety of other treatment options.
