NM404 I-131 (also known as CLR 131) is a phospholipid ether analog labeled with iodine I-131, used as radiotherapeutic and positron emission tomography (PET) radioimaging agent. Upon infusion, the drug accumulates in tumor cells and is retained for a long time because of the decreased activity of a phospholipase D. The drug is being developed by Cellectar Biosciences and is investigated in clinical trials against multiple myeloma and hematologic malignancies. In 2014, the FDA granted orphan drug designation for CLR 131 for the treatment of multiple myeloma.
