These drugs target molecules known as immune checkpoints, which are proteins that regulate the activity of immune cells. By blocking these checkpoints, checkpoint inhibitors help to unleash the immune system's response against cancer cells. Examples include drugs like pembrolizumab (Keytruda) and nivolumab (Opdivo).
Opdivo (nivolumab) and Keytruda (pembrolizumab) are two immunotherapy drugs used to treat a number of different types of cancer. They are monoclonal antibodies that have similar efficacy and safety profiles and are both programmed death receptor-1 (PD1) inhibitors, which were first approved in the US in 2014.

Chimeric Antigen Receptor T-cell therapy (CAR-T) involves modifying a patient's own T cells in the laboratory to express chimeric antigen receptors (CARs) that can recognize and bind to specific proteins on cancer cells. The modified CAR-T cells are then infused back into the patient, where they can target and kill cancer cells.

This approach involves isolating immune cells, known as Tumor-infiltrating lymphocytes (TILs), from a patient's tumor. The TILs are then expanded and activated in the laboratory before being reinfused into the patient.

These are laboratory-produced antibodies designed to target specific proteins on cancer cells. Monoclonal antibodies can work by directly attacking cancer cells, blocking growth signals, or triggering immune responses against cancer. Examples include drugs like rituximab (Rituxan), trastuzumab (Herceptin), and cetuximab (Erbitux).
These drugs aim to modulate the immune system to enhance its ability to recognize and attack cancer cells. They can include cytokines, such as interferons and interleukins, which help stimulate immune responses. Other immune system modulators include immune stimulatory agents like talimogene laherparepvec (T-VEC), an oncolytic virus therapy.

These vaccines are designed to stimulate the immune system to recognize and attack cancer cells. Unlike preventive vaccines that aim to prevent infections, therapeutic vaccines are used in patients who already have cancer. They can include tumor-specific antigens or whole tumor cells, along with immune stimulants to enhance the immune response.
