What is Keytruda?
Keytruda is an advanced immunotherapy medication used to treat several types of cancer. Its active ingredient, pembrolizumab, is a type of protein called a monoclonal antibody. This therapy is highly targeted. It is designed to work with your body’s immune system. Unlike traditional chemotherapy, it does not directly kill cancer cells. Instead, it helps your immune cells fight the cancer more effectively.
How does Keytruda work?
Keytruda works by blocking a specific protein called PD-1 on your immune cells, known as T-cells. Some cancer cells use a related protein, PD-L1, to bind to PD-1. This binding acts like a brake, stopping the T-cells from attacking the cancer. Keytruda prevents this connection from happening. By blocking PD-1, it releases the brake on the immune system. This allows your T-cells to recognize and attack cancer cells throughout your body.
Who is Keytruda for?
Keytruda is prescribed for adults and some children with specific types of cancer. It is often used when the cancer is advanced, has spread, or has not responded to other treatments. The FDA has approved it for conditions like melanoma, lung cancer, and many others. It is also a treatment option for any solid tumor that is identified as microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR). Your oncologist will determine if Keytruda is right for you based on your cancer type and specific biomarkers.
Dosage and administration
Keytruda is given as an intravenous (IV) infusion into a vein by a healthcare provider. The infusion process is generally quick, lasting about 30 minutes. Most patients receive a dose of 200 mg every three weeks or 400 mg every six weeks. Your doctor will decide the best dose and schedule for your specific situation. Treatment continues for as long as it is effective and side effects are manageable. Because it is a biologic drug, Keytruda must be stored in a refrigerator and protected from light.
Side effects
Keytruda may cause side effects ranging from mild to severe as it changes how your immune system works. Common side effects include fatigue, rash, itching, joint pain, diarrhea, and nausea. These often happen because the immune system is more active. More serious side effects can also occur. These are known as immune-mediated adverse reactions. This is when the newly active immune system attacks healthy organs. This can affect the lungs (pneumonitis), liver (hepatitis), and intestines (colitis). It is critical to report any new symptoms to your doctor right away.
