Our Story

TZOFEN Biological Therapeutics was founded in Jerusalem in 2018 to bring cutting-edge, next-generation oncolytic virus technology to help cancer patients everywhere in the world. Driven by our vision, our mission is to develop first-in-class, broadly applicable, product candidates, that are designed to be safe, potent, and systemically deliverable, to treat cancer patients across a variety of tumor types. Supported by scientists, clinicians, and advisors, we are working to advance the field by developing a new generation of optimally designed, oncolytic viruses. At the core of our approach is a cancer-selective gene therapy platform that utilizes modified retrovirus vectors, which are designed to specifically deliver therapeutic genes into the DNA of cancer cells.

Our technology can destroy cancer cells with fewer side effects, keeping patients’ healthy tissue intact while the tumor is eliminated.
