Based on RECIST 1.1 criteria, subjects with cancer of appendices, endometrium and gallbladder showed a substantial decline in tumour burden.

ImmVira chairwoman and CEO Dr Grace Guoying Zhou said: “The development of intravenously administered oncolytic virus products has long been a challenging bottleneck. 

“Oncolytic viruses must overcome numerous hurdles, such as neutralisation by antibodies or the risk of cytokine storms, in order to effectively reach tumour sites with a sufficient number of viruses to achieve anti-tumour effects. 

“With the successful Phase I clinical study results of MVR-T3011 IV, a global-first clinical-stage intravenous oHSV product, our company is now fully confident and committed to expediting clinical explorations in colorectal cancer, non-small cell lung cancer, and other indications, including combination treatments with immune checkpoint inhibitor or chemotherapy.”
