Inotuzumab ozogamicin — Uses, Dosage, Side Effects & Safety

Drug class: Antineoplastic agent; Anti-CD22 monoclonal antibody-drug conjugate

Overview

Inotuzumab ozogamicin is a prescription medicine used to treat adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL), a type of cancer affecting the blood and bone marrow. It is typically used when other treatments have not worked or the disease has returned. This medication works by targeting a protein called CD22 found on the surface of cancerous B-cells. Inotuzumab ozogamicin is a monoclonal antibody linked to a chemotherapy drug, which helps deliver the medicine directly to the cancer cells, reducing their ability to grow and multiply. Key points for patients: Inotuzumab ozogamicin is given as an intravenous infusion in a hospital or clinic setting. It can cause serious side effects, so regular monitoring and follow-up with your healthcare team are essential. Always discuss any symptoms or concerns with your doctor.
