VIDAZA is recommended by National Comprehensive Cancer Network (NCCN) Guidelines in the US as a front-line treatment. In a global Phase 3 trial (AZA-001) involving intermediate-2 and high-risk MDS patients, VIDAZA significantly prolonged the median overall survival to 24.5 months compared with 15 months for the conventional care regimens (CCR- best supportive care, low-dose cytarabine or intensive chemotherapy) group. In the VIDAZA group, 45% of patients who were dependent on red blood cell transfusions at baseline became transfusion independent compared with 11% in the CCR group.There was a higher objective response rate among patients treated with VIDAZA (49%) as compared to the CCR arm (29%). VIDAZA also delayed the onset of AML for these patients (17.8 months vs.11.5 months). The most common grade 3-4 events were peripheral blood cytopenias for all treatments.

About Myelodysplastic Syndrome, Acute Myeloid Leukemia and Chronic Myelomonocyte Leukemia
MDS is a group of conditions that can occur when the bloodforming cells in the bone marrow become abnormal. This leads to low numbers of one or more types of blood cells. 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® (Azacitidine for Injection)
VIDAZA is a nucleoside metabolic inhibitor indicated in
In the US, 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), most frequently observed adverse reactions occurring in at least 5% of patients 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, an international, multicenter, open-label, randomized trial in MDS patients with RAEB, RAEB-T or modified CMMoL according to FAB classification and
Because treatment with VIDAZA is associated with anemia, neutropenia and thrombocytopenia, complete blood counts should be performed as needed to monitor response and/or 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. Females of reproductive potential should be advised to avoid pregnancy during treatment with VIDAZA. Males with female sexual partners of reproductive potential should not father a child and should use effective contraception during treatment with VIDAZA.
The importance of the drug to the mother should be taken into consideration before the breastfeeding mothers decide to discontinue breastfeeding or the drug.
