Keytruda, also known as pembrolizumab, is an immune checkpoint inhibitor drug used to treat various types of cancer. While the drug has been shown to be effective in treating cancer, the long-term benefits of Keytruda are still being studied.

According to Drug Patent Watch [1], Keytruda has been approved by the FDA for the treatment of several types of cancer, including melanoma, lung cancer, head and neck cancer, and Hodgkin lymphoma. The drug works by blocking a protein called PD-1, which helps cancer cells evade the immune system. By blocking PD-1, Keytruda allows the immune system to attack and destroy cancer cells.

While Keytruda has been shown to be effective in treating cancer, there are also potential long-term side effects associated with the drug. As reported by Cancer Currents [2], immune checkpoint inhibitors like Keytruda can cause autoimmune side effects, where the immune system attacks healthy cells in the body. These side effects can occur months or even years after treatment with Keytruda has ended, and can include problems with the lungs, liver, and thyroid gland, as well as joint pain and skin problems.

However, as reported by GoodRx [3], the long-term benefits of Keytruda are still being studied. While the drug has been shown to improve survival rates in patients with certain types of cancer, it is not yet clear how long these benefits will last. Ongoing clinical trials are investigating the long-term effects of Keytruda, including its potential to prevent cancer recurrence and improve overall survival rates.

In conclusion, Keytruda is an effective treatment for several types of cancer, but its long-term benefits are still being studied. While the drug has been shown to improve survival rates in some patients, there are also potential long-term side effects to consider. Ongoing research will help to further understand the long-term benefits and risks associated with Keytruda.
