This is single arm a Phase 2, single center study of talimogene laherparepvec (TVEC) to treat low risk cutaneous squamous cell carcinomas (cSCC).


The purpose of this study is to find out more about talimogene laherparepvec (also known as OncoVEXGM-CSF or IMLYGIC®) in people with a healthy immune system with confirmed low-risk squamous cell carcinoma. Usually, low-risk SCC is treated with a surgical procedure, but surgery can be challenging when patients have: multiple SCCs on their body, when the SCC is on a challenging place on the body to remove or when patients are older or have diseases that place them at risk for surgery related complications. Immune therapy is a treatment that uses certain parts of a person's immune system to fight disease. Immune therapy is a proven therapeutic approach in many cancers, including melanoma, another type of skin cancer.

Talimogene laherparepvec (TVEC) is made from a modified herpes simplex virus type 1 (HSV-1, the "cold sore" virus). The virus' genes were modified in a laboratory so that it produces a protein called human granulocyte macrophage colony-stimulating factor (GM-CSF), which multiplies and grows in tumor cells. Human GM-CSF is normally produced by various cells within the body and is used as a medicine to treat patients with white blood cell counts that are too low. This modified HSV-1 produces a protein that acts on tumor cells and stimulates the immune system. TVEC is administered by injection with a needle directly into one or more tumors and works by directly destroying cancer cells and enhancing immune response to destroy cancer cells.
