About T-SIGn^®

Tumor-Specific Immuno-Gene (T-SIGn^®) therapy is a novel clinical stage, systemically dosed treatment modality designed to selectively deliver multi-gene payloads of immunotherapeutic proteins to solid tumors to trigger the immune system to fight cancer. The platform leverages enadenotucirev, a chimeric group B adenovirus, as a viral vector system for the delivery of therapeutic transgenes to cancer cells. The T-SIGn^® viral vector platform has been clinically validated for its ability to selectively express therapeutic transgenes in targeted solid tumor tissue following intravenous dosing of a T-SIGn^® therapeutic. The PsiOxus T-SIGn^® programs currently in the clinic include NG-350A (producing an immune activating antibody) and NG-641 (producing a bispecific antibody targeting the tumor stroma together with additional immunomodulatory transgenes). These programs both aim to reprogram the solid tumor microenvironment to promote anti-tumor immunity. In addition, PsiOxus is progressing NG-796A (an immune cell attracting and activating therapy) which is currently in IND-enabling studies and was developed through an ongoing collaboration with the Parker Institute for Cancer Immunotherapy. PsiOxus also has a number of earlier stage T-SIGn^® preclinical programs.
