PR-104 is a drug from the class of hypoxia-activated prodrugs (HAPs), which is being researched as a potential anti-cancer therapeutic agent. It is an advanced nitrogen mustard prodrug which is designed to be selectively converted to its cytotoxic active form only inside hypoxic tissues such as that found in solid tumours.^[1][2][3] Following initial pre-clinical studies it was serendipitously discovered that this conversion happens at particularly high efficiency in tumours associated with acute myeloid leukemia and acute lymphoblastic leukemia, and subsequent clinical trials have focused on developing PR-104 as a specific treatment targeted at these cancer subtypes.^[4][5][6]
