Cellectar Biosciences has achieved 94 percent tumor reduction in a patient taking part in a clinical trial for the company’s cancer treatment.
The Madison-based pharmaceutical firm’s product is called CLR 131. It’s used to precisely deliver radiation to malignant tumor cells while avoiding healthy cells that would be damaged by the treatment.
The drug is currently being used in a Phase 2 clinical study at 10 cancer centers around the United States for patients with a host of different blood-related cancers. These include multiple myeloma as well as several types of leukemia and lymphoma, which affect the body’s systems for fighting infection and creating new blood cells.
The patient in question is a 67-year-old female diagnosed with Waldenstrom macroglobulinemia, a rare cancer which starts in the white blood cells. Afflicted individuals have bone marrow that’s producing far too many white blood cells, leading to a build-up of proteins in the blood that causes problems.
