Campath is used to treat B-cell chronic lymphocytic leukemia (CLL), particularly in patients who have not responded to other treatments, and has also been used in autoimmune conditions such as multiple sclerosis.
Campath is a monoclonal antibody that targets the CD52 antigen found on the surface of mature lymphocytes. When it binds to CD52, it triggers the immune system to destroy these cells through antibody-dependent and complement-mediated mechanisms.
Campath is administered as an intravenous infusion and requires close medical supervision. Common side effects include infusion reactions, fever, chills, and increased risk of infections due to immunosuppression. Regular blood monitoring is necessary during treatment. Patients should receive appropriate prophylaxis and monitoring for autoimmune complications.
