Pembrolizumab (formerly lambrolizumab, brand name Keytruda) is a medication used in cancer immunotherapy.[3] This includes to treat melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, cervical cancer, and stomach cancer.[3] It is given by slow injection into a vein.[3]
Common side effects include tiredness, musculoskeletal pain, decreased appetite, itchy skin, diarrhea, nausea, rash, fever, cough, difficulty breathing, constipation, and abdominal pain.[3] Other side effects include liver problems and kidney problems.[3] Use during pregnancy or breastfeeding is not recommended.[4] It is an IgG4 isotype humanized antibody that blocks a protective mechanism of cancer cells and thereby, allows the immune system to destroy them.[3] It targets the programmed cell death protein 1 (PD-1) receptor of lymphocytes.[3]
Pembrolizumab was approved for medical use in the United States in 2014.[3] In 2017, it was approved for any non removable or metastatic solid tumor with certain genetic anomalies (mismatch repair deficiency or microsatellite instability).[5] It is on the World Health Organization's List of Essential Medicines as an alternative for nivolumab.[6] In the United Kingdom the typical dose costs 5,260 pounds every three weeks as of 2020.[7] In the United States this amount costs 8,760 USD.[8]
