For which conditions is this drug approved? POLIVY in combination with bendamustine and a rituximab product is indicated for the treatment of adults with relapsed or refractory diffuse large B-cell lymphoma after two or more prior therapies.
What is the mechanism of action? POLIVY is a novel targeted immunotherapy that combines an antibody with a chemotherapy drug. The antibody binds to a specific protein called CD79b found only on B cells. Once the antibody is bound to the B cells, the chemotherapy drug is released into the cancer cells.
How is POLIVY typically given (administered)? POLIVY is given by intravenous infusion, usually once every three weeks. Each infusion typically takes about 90 minutes.
How are patients typically monitored? Before taking POLIVY, discuss any medical conditions with your healthcare provider. Patients receiving POLIVY are monitored with blood work and other laboratory tests and are monitored for infusion related reactions. POLIVY can harm an unborn baby, so women should not become pregnant while taking this drug. Women who are breastfeeding should not take POLIVY because it may cause harm to a newborn baby.
