Types of Immunotherapy For Cancer

Immunotherapy employs your body’s immune system to fight cancer, encompassing diverse treatments. Some enhance overall disease-fighting capabilities, while others train the immune system to target specific cells within tumors.

Immune Checkpoint Inhibitors

Immune checkpoint inhibitors represent a groundbreaking class of drugs in cancer treatment, revolutionizing the way we combat the disease. To understand how they work, let’s delve into the intricate mechanisms of the immune system.

When our bodies face threats like bacteria or viruses, the immune system springs into action, mobilizing an army of cells to eliminate the invaders. However, this response needs to be carefully regulated to prevent the immune system from attacking healthy tissues. This regulation is achieved through a system of “brakes” called checkpoints. These checkpoints act as molecular switches that can either activate or suppress immune responses.

In cancer, malignant cells often exploit these checkpoints to evade detection and destruction by the immune system. They manipulate the checkpoints to suppress immune responses, allowing them to proliferate and spread unchecked. This evasion mechanism is a significant hurdle in cancer treatment, as it renders traditional therapies less effective.

Enter immune checkpoint inhibitors. These drugs work by releasing the brakes on the immune system, essentially removing the barriers that prevent it from attacking cancer cells. By blocking specific proteins known as PD-1, PD-L1, CTLA-4, and TF on the surface of immune cells, checkpoint inhibitors unleash the full potential of the immune system to recognize and destroy cancerous growths.

PD-1 inhibitors, such as Pembrolizumab, Nivolumab, and Cemiplimab, target the PD-1 protein on immune cells. By blocking PD-1, these drugs prevent cancer cells from hijacking the immune response and allow immune cells to recognize and eliminate tumors effectively.

Similarly, PD-L1 inhibitors like Atezolizumab, Avelumab, and Durvalumab target the PD-L1 protein, which cancer cells often overexpress to evade immune surveillance. By blocking PD-L1, these inhibitors restore the immune system’s ability to recognize and attack cancer cells.

Another type of immune checkpoint inhibitor targets CTLA-4, a protein that regulates immune responses. Ipilimumab is a CTLA-4 inhibitor that disrupts this regulatory mechanism, allowing immune cells to mount a robust attack against cancer cells.

In addition to these well-known checkpoints, recent advancements have led to the discovery of new targets for immune checkpoint inhibitors. Tisotumab vedotin-tftv is a promising TF inhibitor that holds potential in cancer treatment by inhibiting a novel target called TF.

Adoptive Cell Therapies (ACT)

Adoptive Cell Therapies (ACT) represent a cutting-edge approach in cancer treatment, harnessing the power of the body’s immune system to target and eliminate cancer cells. This innovative group of treatments involves modifying or enhancing a patient’s own immune cells to enhance their ability to recognize and attack cancerous growths. 

Let’s delve into the different types of ACT and their mechanisms of action:

Tumor-infiltrating lymphocyte (TIL) therapy:

  • TIL therapy involves harvesting T cells from the patient’s tumor tissue.
  • These T cells, known as tumor-infiltrating lymphocytes (TILs), are then cultured and expanded in a lab to increase their numbers.
  • The activated TILs are reintroduced into the patient’s body, where they target and attack the cancer cells.

Engineered T-cell receptor (TCR) therapy:

  • TCR therapy entails isolating T cells from the patient’s blood and genetically modifying them in a lab.
  • These modified T cells are engineered to express receptors that recognize specific antigens present on the surface of cancer cells.
  • Once reintroduced into the patient’s body, the engineered T cells can efficiently identify and destroy cancer cells bearing the targeted antigens.

CAR T-cell therapy:

  • CAR T-cell therapy involves modifying a patient’s T cells to express chimeric antigen receptors (CARs) on their surface.
  • These CARs are designed to recognize and bind to specific antigens present on cancer cells.
  • Two FDA-approved CAR T-cell therapies, Tisagenlecleucel and Axicabtagene ciloleucel, have shown remarkable efficacy in treating certain types of leukemia and lymphoma.
  • Ongoing research aims to expand the applicability of CAR T-cell therapy to other cancer types and explore novel approaches, such as using CAR T cells derived from healthy donors.

Natural killer (NK) cell therapy:

  • NK cell therapy involves enhancing the anti-cancer activity of natural killer cells, which are innate immune cells capable of recognizing and eliminating cancer cells.
  • By adding CARs to NK cells, researchers aim to enhance their specificity and potency in targeting cancer cells, thereby improving treatment outcomes.

Despite the immense potential of ACT, challenges such as cytokine release syndrome and neurotoxicity warrant further investigation and refinement of these therapies. Nevertheless, ACT holds great promise as a personalized and effective treatment strategy for various malignancies, offering hope to patients with advanced or refractory cancers.

Monoclonal antibodies (mAbs)

Monoclonal antibodies (mAbs) are an innovative form of cancer treatment that leverages the body’s natural defense system to target and destroy cancer cells. These antibodies, which are proteins produced by the immune system, possess the unique ability to recognize and bind to specific proteins called antigens on the surface of cancer cells. By doing so, they initiate a series of immune responses that lead to the destruction of cancerous tissues.

There are several types of monoclonal antibodies used in cancer treatment, each with its own mechanism of action and therapeutic benefits:

Naked Monoclonal Antibodies:
