Mechanism of Action

 

  • Keytruda (pembrolizumab) is a monoclonal antibody that targets the PD-1 receptor on T-cells, which normally acts as a checkpoint to prevent overactivation of the immune system.
  • Many cancer cells express PD-L1 or PD-L2 proteins that bind to PD-1, effectively turning off the immune response against these tumors.
  • By binding to PD-1, Keytruda blocks the interaction with PD-L1 and PD-L2, releasing the "brake" on the immune system and allowing T-cells to recognize and attack cancer cells more effectively.

 

Clinical Impact

 

  • This reactivation of the immune system has led to significant benefits in treating several types of cancer, including melanoma, lung cancer, head and neck cancers, and others.
  • Keytruda can shrink tumors and improve survival outcomes for many patients by harnessing the body’s natural ability to fight cancer.

 

Important Considerations

 

  • While Keytruda can be very effective, it may lead to immune-related side effects, such as inflammation of the lungs, intestines, liver, or endocrine organs, due to the heightened immune activity.
  • Patients undergoing treatment must be closely monitored by healthcare professionals to manage potential side effects and achieve the best balance between efficacy and safety.
  • Its use is often based on specific biomarkers (like PD-L1 expression) to identify patients who are most likely to benefit from the therapy.

Why prevention is more effective than allergy medicine

Exposure therapy:
Train your immune system to fight allergies rather than treat them with medications
Desensitization: Symptoms subside as your body desensitized to allergies reducing or eliminating the need for daily medication
Prevention: Immunotherapy helps prevent and fight allergies at the source
