The patent, titled "ONCOLYTIC VIRUS EXPRESSING A CAR T CELL TARGET AND USES THEREOF" protects the method of composition and method of use of onCARlytics through to 2038.

Exclusively licensed to Imugene, OnCARlytics is a CD19-expressing oncolytic virus that enters solid tumour cells and forces them to express the CD19 protein on the cell surface, presenting a target for CD19 targeting therapies.

Imugene’s OASIS dose escalation trial of onCARlytics is being conducted at up to ten sites in the United States, with up to approximately 40 patients proposed to take part in the trial.

Imugene MD & CEO Leslie Chong said: "Intellectual property has remained a priority for our innovative range of immuno-oncology assets, and to have onCARlytics protected in a major market like China is an integral part of this strategy."
