Mechanism of action

Sasanlimab is an antibody drug that works by targeting a molecular 'off switch' that cancer cells use to escape detection. Normally, cancer cells express a protein called PD-L1 on their surface, which interacts with immune cells and essentially tells them to ignore the cancer. By blocking this interaction, Sasanlimab removes the cancer's protective cloak, making it visible to your immune system again. Once this block is in place, immune cells called T cells can recognize cancer cells as foreign invaders and attack them. This reactivation of the immune system's anti-cancer response is the key mechanism behind how drugs like Sasanlimab work to slow or stop tumor growth. The prefilled syringe format makes administration simpler and more convenient compared to traditional IV infusions, allowing for more flexible treatment scheduling. The effectiveness of Sasanlimab depends on whether your specific cancer expresses sufficient PD-L1 levels, which is why testing is often performed before treatment begins. This targeted approach aims to improve outcomes while potentially having a better side effect profile than broader chemotherapy treatments, though it does activate the immune system in ways that require careful monitoring.
