What is IMFINZI?

IMFINZI, the brand name for durvalumab, represents a significant advancement in cancer immunotherapy. It’s a monoclonal antibody, a type of protein designed to target specific molecules within the body. This targeted approach distinguishes it from traditional chemotherapy, which often affects healthy cells alongside cancerous ones. Durvalumab’s specific target is programmed death-ligand 1, or PD-L1, a protein frequently found on the surface of cancer cells.

The significance of targeting PD-L1 lies in its role in helping cancer cells evade the immune system. Healthy immune cells, specifically T cells, normally recognize and destroy cancerous cells. However, cancer cells often use PD-L1 to send signals that essentially “turn off” these T cells, allowing tumors to grow unchecked. By blocking PD-L1, IMFINZI removes this brake on the immune system, enabling T cells to resume their attack on cancer cells. This mechanism makes IMFINZI a powerful tool in the fight against various cancers, offering a novel approach to treatment.

Importantly, IMFINZI is not a standalone treatment; it’s often used in combination with other therapies or as a subsequent treatment following other interventions. The precise role and application of IMFINZI are determined by a physician based on the specific type and stage of cancer, as well as the overall health of the patient. The concentrate for infusion solution, available in 50mg/ml vials, facilitates intravenous administration.
