Generic Name: bendamustine (ben-duh-MU-steen) hydrochloride
Trade Name: Treanda®
For which conditions is this drug approved? Treanda is approved for treatment of chronic lymphocytic leukemia (CLL) and indolent (slow-growing) B-cell non-Hodgkin’s lymphoma (NHL) that has progressed during or within six months of treatment that includes the agent Rituxan® (rituximab).
What is the mechanism of action? Treanda belongs to a group of drugs referred to as alkylating agents. Treanda is believed to produce its anticancer effects by preventing DNA function properly. This results in cellular death.
How is Treanda typically given (administered)? Treanda is available in two formulations, a solution (Treanda Injection) and a lyophilized powder (Treanda for Injection). Treanda is administered into a vein (intravenous). The dose depends on several factors, including the condition being treated, the size of the patient, the particular regimen being used and the overall health of the patient.
How are patients typically monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with Treanda. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys or liver. Patients may also undergo physical examinations, scans, blood draws and other measures to assess side effects and response to therapy.
Rarely, patients will experience an allergic reaction to Treanda, so they will be closely monitored for symptoms including low blood pressure, fever, chills, difficulty breathing, wheezing, and mental confusion. Patients are also monitored for skin reactions and tumor lysis syndrome, a condition in which the byproducts of dying cancer cells can cause harm to certain organs such as the kidneys.
