About Pembrolizumab

A PD 1 immune checkpoint inhibitor that revolutionized cancer treatment. Pembrolizumab or Keytruda treats melanoma, lung cancer, and many other cancers by releasing the brakes on the immune system. It allows T cells to attack tumors that were hiding from immune detection. Pembrolizumab became the first immunotherapy approved for tumors based on genetic markers rather than cancer type. It became the top selling drug in the world, with annual sales exceeding 25 billion dollars for Merck. It represents the promise of cancer immunotherapy.
