ImmVira's MVR-T3011 oncolytic virus program has innovated with a genetically engineered oncolytic herpes simplex virus-1 (oHSV-1) to enhance the known oncolytic effects of oHSV-1. Through gene recombinant technologies,PD-1 antibody and interleukin-12immune modulators are expressed within the virus.Oncolysis is achieved with additional immune response stimulation while keeping the boosted immune activity limited to the locality of MVR-T3011 to achieve a potentially favorable safety profile. The MVR-T3011 intratumoral program aims to target most solid malignant tumors with both remission rate improvement and safety improvement over immune modulator monotherapies. As part of the agreement,Shanghai Pharma will receive an exclusive license and gain access to ImmVira's MVR-T3011 virus for clinical development,manufacturing and commercialization within certain fields of use in mainland China,Hong Kong,Macau and Taiwan (the Greater China region).
