Generic Name : azacitadine (aye-zuh-CYE-ta-deen)
Trade Name: Vidaza®
For which conditions is Vidaza approved for? Vidaza is indicated for the treatment of the following types of myelodysplastic syndromes: refractory anemia or refractory anemia with ringed sideroblasts (if accompanied by neutropenia or thrombocytopenia or requiring transfusions), refractory anemia with excess blasts, and refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia.
What is the mechanism of action? Vidaza belongs to a group of drugs called a nucleoside analogue. Vidaza produces its anti-cancer effects by inhibiting the ability of DNA replication. The suppression of DNA replication tends to affect faster replicating cells, such as cancer cells, ultimately causing cellular death.
How is Vidaza typically given (administered)? Vidaza is typically administered subcutaneously (injection under the skin). The dose and scheduling in which Vidaza is administered is dependent upon many factors, including the condition being treated, the particular treatment regimen being utilized, the patient’s height and weight, overall health, and the patient’s tolerance of therapy. Patients may also receive anti-nausea medication prior to treatment with Vidaza.
How are patients typically monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with Vidaza. Typically, blood may be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys or liver. Physical examinations, scans, or other measures may also be utilized to assess side effects and response to therapy.
