Cancer Immunotherapy

Under normal circumstances, our immune system can recognize and eliminate tumor cells. But in order to survive and grow, tumor cells can adopt different strategies to restrain the body’s immune system. Sometimes, they can even promote the development and progression of a tumor. These characteristics of tumor cells are known as immune-resistance.

Immunotherapy is a novel class of inhibitors that function as a tumor suppressing factor via modulation of immune cell-tumor cell interaction. These checkpoint blockers are rapidly becoming a highly promising cancer therapeutic approach that yields remarkable responses for patients with a broad spectrum of cancers, such as melanoma, non-small cell lung cancer and kidney cancer. In recent times, more than five immunotherapy drugs have been approved by the Food and Drug Administration (FDA) of the United States for clinical application.

 

 

Monoclonal Antibody Immune Checkpoint Inhibitors

PD-1/PD-L1 and PD-1/PD-L1 antibodies

秒速快三PD-1/PD-L1 antibodies can block PD-L1 on the surface of tumor cells, reactivating the function of cytotoxic T cells to promote anticancer immune responses.

秒速快三Anti PD-1 monoclonal antibodies Pembrolizumab (Keytruda™) and Nivolumab (Opdivo™) have been approved by the FDA for advanced melanoma, non-small cell lung cancer, non-Hodgkin’s lymphoma, and head and neck squamous cell carcinomas. Nivolumab has also been approved by the FDA for the treatment of kidney and urinary tract carcinomas, etc. In addition, PD-L1 inhibitors Atezolizumab (Tecentriq™), Avelumab (Bavencio™), and Durvalumab (Imfinzi™) have also been tested in Phase III clinical studies, covering many types such as non-small cell lung cancer, melanoma, and bladder cancer.

 

CTLA-4 inhibitors

The CTLA-4 inhibitor Ipilimumab, the first approved immune checkpoint inhibitor drug, has been approved by the FDA for adjuvant treatment of Stage III melanoma and treatment for advanced melanoma.

Other monoclonal antibodies

Other monoclonal antibodies such as TNF receptor family OX40 and 4-1bb monoclonal antibodies are still under development.

Common Adverse Effects of Monoclonal Antibody Immune Checkpoint Inhibitors

秒速快三Compared with chemotherapy, immune therapy generally has a lower incidence of adverse effects. Although autoimmune disorder does indeed sometimes occur, with appropriate dosage tested in Phase I clinical studies, the overall incidence of serious adverse events (Grade 3-4) is still not high.

秒速快三The most common adverse effects are fatigue, loss of appetite, nausea, weakness, and rash. Most adverse effects are reversible and manageable.

秒速快三Immunotoxicity can occur at any time. According to the median time of onset, it can be divided into early (< 2 months) and late (> 2 months) toxicity. Early toxicity includes skin, gastrointestinal, and liver. Late toxicity includes lung, endocrine glands, and kidney. Some are delayed, with some even occurring after a year of immunotherapy.

秒速快三In case of any adverse effects related to immunotherapy, please contact the medical staff promptly.
