Adcetris® (brentuximab vedotin)
Class: Precision Cancer Medicine-Targeted Therapy
How is Adcetris used? Adcetris is used for the treatment of Hodgkin lymphoma that has progressed after autologous stem cell transplant or has progressed after at least two prior multi-agent chemotherapy regimens in patients who are not candidates for a stem cell transplant, and for patients with Hodgkin lymphoma with a high risk of progression or relapse after autologous stem cell transplant. In addition, Adcetris is also used for the treatment of systemic anaplastic large cell lymphoma (a type of non-Hodgkin lymphoma) that has progressed after at least one prior multi-agent chemotherapy regimen.
What is the mechanism of action? Adcetris targets a protein known as CD30, which is present on Hodgkin lymphoma cells as well as cells from other cancers, including anaplastic large cell lymphoma. Once Adcetris enters CD30-positive cells, it releases the chemotherapy drug monomethyl auristatin E.
How is Adcetris given (administered)? Adcetris is given as an intravenous (IV) infusion.
How are patients being treated withe Adcetris monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with Adcetris. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems. Patients may undergo physical examinations and other tests to assess side effects and response to therapy.
What are the most common side effects of treatment with Adcetris?
- Low blood cell counts (low levels of white blood cells, red blood cells, and platelets)
- Peripheral sensory neuropathy (a nerve problem that causes pain, numbness, tingling, or swelling of the hands or feet)
