Is Imfinzi a PD-1 inhibitor?
Imfinzi (Durvalumab) a New PD-L1 Inhibitor Approved for the Treatment of Advanced or Metastatic Urothelial Cancer. Urothelial carcinoma is the primary subtype of bladder cancer, which is the sixth most common cancer in the United States.
What are PD-1 drugs?
PD-1 inhibitors and PD-L1 inhibitors are a group of checkpoint inhibitor anticancer drugs that block the activity of PD-1 and PDL1 immune checkpoint proteins present on the surface of cells. Immune checkpoint inhibitors are emerging as a front-line treatment for several types of cancer.
How do PDL1 inhibitors work?
When PD-1 binds to PD-L1, it basically tells the T cell to leave the other cell alone. Some cancer cells have large amounts of PD-L1, which helps them hide from an immune attack. Monoclonal antibodies that target either PD-1 or PD-L1 can block this binding and boost the immune response against cancer cells.
What is the newest immunotherapy?
Nivolumab acts on a protein called PD-1 and is FDA-approved for treating melanoma and several other cancer types. Relatlimab blocks signaling of an inhibitory protein called LAG-3 displayed on immune system T cells, reinvigorating their anti-tumor activity.
What does PD-L1 positive mean?
Some cancer cells have high amounts of PDL1. This allows the cancer cells to “trick” the immune system, and avoid being attacked as foreign, harmful substances. If your cancer cells have a high amount of PDL1, you may benefit from a treatment called immunotherapy.
How do PD-L1 inhibitors work?
The binding of PD-L1 to PD-1 keeps T cells from killing tumor cells in the body (left panel). Blocking the binding of PD-L1 to PD-1 with an immune checkpoint inhibitor (anti-PD-L1 or anti-PD-1) allows the T cells to kill tumor cells (right panel).
What cancers are treated with immune checkpoint inhibitors?

What happens after immunotherapy ends?
Even if immunotherapy no longer works, you have options. You might be able to try other cancer treatments. Or your doctors can give you medicines and other therapies to ease your symptoms so you feel better. Take this time to spend with family and friends, and do the things you love.
How many immunotherapy treatments can you have?
Therapy intervals may range between every two weeks to every four weeks. In April, however, the FDA approved a six-week dosing regimen for the immunotherapy drug, pembrolizumab (KEYTRUDA®), a monoclonal antibody. Currently, there’s no designated end to immunotherapy treatment.
