Received patent covering novel SuperNova technology platform. The patent covers a composition where cells are incubated with an oncolytic virus for a defined period allowing the expression of at least one immunomodulatory protein or recombinant therapeutic protein encoded by the virus, by virtue of association of the virus, with the carrier cell. Calidi has shown preclinically the potential of SuperNova to shield the viral payload from the immune system allowing for its delivery to tumor sites. The SuperNova platform is composed of adipose-derived mesenchymal stem cells loaded with oncolytic vaccinia virus.
