SHENZHEN, China, June 11, 2021 /PRNewswire/ — ImmVira announced that in the Phase II Clinical Trials of its leading oncolytic virus product, MVR-T3011* as intratumoral administration (MVR-T3011 IT), ImmVira has completed the first dosing in both China and the U.S. on May 28 2021 and June 11 2021, respectively.
MVR-T3011, ImmVira’s proprietary next-generation, genetically modified oncolytic herpes simplex virus (“oHSV”), is developed on a novel virus backbone design driven by ImmVira’s innovative insights in oncolytic viruses and superior gene recombinant technology.
