About

Multiple myeloma is a cancer of plasma cells, the white blood cells that normally make antibodies; it often causes no symptoms at first, then brings bone pain, anemia, kidney problems, and infections as it progresses. Zenbexus (iberdomide) is a pill that binds a protein called cereblon, redirecting the cell's recycling machinery to break down specific proteins that myeloma cells rely on. Because it attacks those proteins through a different route than existing myeloma drugs, combining it with other treatments may help control the cancer in people whose disease has come back or stopped responding.
