Combination immunotherapy is an approach that combines different immunotherapeutic agents or strategies to enhance the immune system’s ability to target and destroy cancer cells. Mesothelioma is a rare and aggressive form of cancer that primarily affects the lining of the lungs, abdomen, or heart. Immunotherapy has emerged as a promising treatment option for advanced mesothelioma, although it is still an area of ongoing research.
The most common type of immunotherapy used in mesothelioma is immune checkpoint inhibitors. These drugs block certain proteins that inhibit the immune system’s response, allowing immune cells to recognize and attack cancer cells more effectively. Some of the immune checkpoint inhibitors used in mesothelioma include:
- Pembrolizumab (Keytruda)
- Nivolumab (Opdivo)
While immune checkpoint inhibitors have shown some promise in treating mesothelioma, the response rates have not been as high as in some other cancers. Therefore, researchers are investigating combination immunotherapy approaches to improve the outcomes for mesothelioma patients. Some of the strategies being explored include:
- Combination of Immune Checkpoint Inhibitors: Researchers are testing whether combining different checkpoint inhibitors can have a synergistic effect in mesothelioma treatment. For example, combining nivolumab and ipilimumab has been investigated.
- Chemotherapy and Immunotherapy: Combining chemotherapy with immunotherapy may enhance the immune response and increase the likelihood of tumor shrinkage. This approach is known as chemoimmunotherapy.
- Personalized Immunotherapy: Some trials are focusing on personalized treatment approaches, such as identifying specific antigens on mesothelioma cells and developing vaccines or T-cell therapies to target those antigens.
- Immunotherapy and Other Targeted Therapies: Combining immunotherapy with other targeted therapies that block specific cancer-related pathways is under investigation. This may include agents like bevacizumab, which targets blood vessel formation in tumors.
It’s important to note that clinical trials are ongoing to assess the safety and effectiveness of these combination immunotherapy approaches in mesothelioma. Patients with advanced mesothelioma should work closely with their oncologists to determine the most appropriate treatment options, including potential participation in clinical trials.
The effectiveness of combination immunotherapy in mesothelioma may vary from one patient to another, and the side effects of these treatments can be significant. Therefore, the decision to pursue combination immunotherapy should be made after careful consideration and consultation with a medical team experienced in mesothelioma treatment.
