Replimune Group, Inc. is a clinical-stage biotechnology company. The company is headquartered in Woburn, Massachusetts and currently employs 331 full-time employees. The company went IPO on 2018-07-20. The Company’s proprietary RPx platform is based on a potent HSV-1 backbone intended to maximize immunogenic cell death and the induction of a systemic anti-tumor immune response. RP1 (vusolimogene oderparepvec) is its lead product candidate and is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF intended to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response. The company is also developing additional product candidates, RP2 and RP3, to enhance anti-tumor immune responses and are intended to address additional tumor types, including traditionally less immune responsive tumor types. RP2 additionally expresses an anti-CTLA-4 antibody-like molecule, as well as GALV-GP R- and GM-CSF.
