About Myelodysplastic Syndrome, Acute Myeloid Leukemia and Chronic Myelomonocyte Leukemia
MDS is a heterogeneous group of diseases characterized by bone marrow failure and one or more myelodysplasia. In about one-third of patients with MDS, the disease can progress to a rapidly growing cancer of bone marrow cells called AML.i CMML is a type of cancer that starts in blood-forming cells of the bone marrow and invades the blood; it affects mainly older adults. CMML has features of both MDS and myeloproliferative disorder and is considered the most common disease among myelodysplastic/myeloproliferative diseases.ii
About VIDAZA® (Azacytidine for Injection)
VIDAZA is a nucleoside metabolic inhibitor indicated in
In the U.S. VIDAZA is indicated for the treatment of patients with the following FAB MDS subtypes: refractory anemia (RA) or refractory anemia with ringed sideroblasts (RARS) (if accompanied by neutropenia or thrombocytopenia or requiring transfusions), refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEB-T), and CMML.
Important Safety Information
VIDAZA is contraindicated in patients with a known hypersensitivity to azacitidine or mannitol and in patients with advanced malignant hepatic tumors.
In Study 1 (a randomized, open-label, controlled trial carried out in 53 U.S. sites compared the safety and efficacy of subcutaneous VIDAZA plus supportive care with supportive care alone (“observation”) in patients with any of the five FAB subtypes of myelodysplastic syndromes (MDS)) and Study 2 (a multi-center, open-label, single-arm study of 72 patients with RAEB, RAEB-T, CMMoL, or AML), the most commonly occurring adverse reactions by SC route were nausea (70.5%), anemia (69.5%), thrombocytopenia (65.5%), vomiting (54.1%), pyrexia (51.8%), leukopenia (48.2%), diarrhea (36.4%), injection site erythema (35.0%), constipation (33.6%), neutropenia (32.3%), and ecchymosis (30.5%). Other adverse reactions included dizziness (18.6%), chest pain (16.4%), febrile neutropenia (16.4%), myalgia (15.9%), injection site reaction (13.6%), and malaise (10.9%). In Study 3, the most common adverse reactions by IV route also included petechiae (45.8%), weakness (35.4%), rigors (35.4%), and hypokalemia (31.3%).
In Study 4 (the AZA-001 survival trial), the most commonly occurring adverse reactions were thrombocytopenia (69.7%), neutropenia (65.7%), anemia (51.4%), constipation (50.3%), nausea (48.0%), injection site erythema (42.9%), and pyrexia (30.3%). The most commonly occurring Grade 3/4 adverse reactions were neutropenia (61.1%), thrombocytopenia (58.3%), leukopenia (14.9%), anemia (13.7%), and febrile neutropenia (12.6%).
Because treatment with VIDAZA is associated with anemia, neutropenia and thrombocytopenia, complete blood counts should be performed as needed to monitor response and toxicity, but at a minimum, prior to each dosing cycle.
Because azacitidine is potentially hepatotoxic in patients with severe preexisting hepatic impairment, caution is needed in patients with liver disease. In addition, azacitidine and its metabolites are substantially excreted by the kidneys and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function.
VIDAZA may cause fetal harm when administered to a pregnant woman. Women of childbearing potential should be apprised of the potential hazard to the fetus. Men should be advised not to father a child while receiving VIDAZA.
Nursing mothers discontinue nursing or the drug, taking into consideration the importance of the drug to the mother.
