Year Founded

2019

Lead Product in Development

VET3-TGI is a novel oncolytic immunotherapy developed using KaliVir’s proprietary VET™ platform, designed to selectively replicate in tumor cells, stimulate local immune responses and remodel the immunosuppressive tumor microenvironment through the expression of IL-12 and a TGFβ inhibitor. By combining potent local immune activation with blockade of a key immunosuppressive pathway, the program is designed to drive durable, systemic anti-tumor responses across solid tumors.
