Immunotherapy Drugs Type Analysis
- Antibody Drugs: Antibody drugs, part of the broader group of immunotherapies, are designed to enhance the immune system’s ability to fight cancer. These drugs, often referred to as monoclonal antibodies, are lab-engineered immune system proteins that specifically target antigens on cancer cells. Once bound, they mark the cancer cells for destruction by the immune system. Rituximab, for example, targets CD20 on B cells and certain cancer cells, leading to their elimination by the immune system.
- Inhibitor Drugs: Inhibitor drugs, a subset of immunotherapies known as checkpoint inhibitors, work by blocking immune checkpoint proteins that cancer cells use to protect themselves from the immune system. By inhibiting these checkpoints, such as PD-1 or CTLA-4, these drugs enable T cells to more effectively attack and kill cancer cells. Drugs like ipilimumab and nivolumab are examples of this therapy, which has been shown to improve outcomes in several cancers, including melanoma and non-small cell lung cancer.
- Interferons and Interleukins: Interferons and interleukins are types of cytokines that naturally occur in the body and can be used in cancer treatment to modulate the immune system. As a part of immunotherapy, interferons help to boost the immune system’s ability to fight cancer by enhancing the activity of immune cells. Interleukins, like IL-2, stimulate the growth and activation of other immune cells, such as T cells and natural killer cells, which are critical in combating cancer cells.
- Cancer Vaccines: Cancer vaccines are a form of immunotherapy designed to elicit an immune response against cancer-specific antigens. They work by introducing one or more antigens into the body, often in a modified form, to trigger an immune response that will target and destroy cancer cells. These vaccines aim to prevent cancer from developing or to treat existing cancers by strengthening the body’s natural defenses. They differ from traditional vaccines in that they are typically used as a treatment rather than for prevention.
- Other Types: Other types of immunotherapy include treatments like Bacillus Calmette-Guérin (BCG) for bladder cancer, which provokes an immune response directly within the bladder. There are also newer forms of therapies being researched, such as T-cell transfer therapy, which enhances the natural cancer-fighting abilities of immune cells by modifying them in the laboratory before reintroducing them into the patient’s body.
Emerging Trends
- Immunogenic Cell Injury vs. Death: Research has shifted focus from immunogenic cell death to the concept of immunogenic cell injury. It was discovered that cancer cells injured by chemotherapy but not killed could more effectively stimulate the immune system when combined with checkpoint blockade therapies, offering a new avenue for enhancing immunotherapy efficacy.
- Targeting the TIGIT/CD155 Axis in Pancreatic Cancer: A novel approach in pancreatic cancer involves targeting the TIGIT/CD155 axis, which is responsible for T cell exhaustion. Combination therapies that include TIGIT inhibitors with PD-1 inhibitors and CD40 agonist antibodies are showing promise in overcoming immune resistance mechanisms and rejuvenating exhausted T cells.
- STING Pathway in Cancer Treatment: The STING pathway, involved in immune response, is being leveraged to develop new cancer vaccines and therapies. Research indicates that enhancing STING signaling could dramatically improve the effectiveness of checkpoint blockade therapies and potentially offer new treatments for patients with loss-of-function mutations in the STING gene.
