Azatend 100mg Injection

Azacitidine for injection is a nucleoside metabolic inhibitor indicated for the treatment of: Adult patients with the following FAB myelodysplastic syndrome (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 chronic myelomonocytic leukemia (CMMoL). Myelodysplastic Syndromes (MDS) Azacitidine for injection is indicated for treatment of adult patients with the following French-American-British (FAB) myelodysplastic syndrome subtypes: refractory anemia (RA) or refractory anemia with ringed sideroblasts (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 chronic myelomonocytic leukemia (CMMoL). Pediatric use information is approved for Celgene Corporation's Vidaza (Azacitidine for injection).

Risks of Substitution with Other Azacitidine Products: Do not substitute Azacitidine for oral Azacitidine. Anemia, Neutropenia and Thrombocytopenia: Monitor complete blood counts (CBC) frequently. Hepatotoxicity: Patients with severe preexisting hepatic impairment are at higher risk for toxicity. Renal Toxicity: Monitor patients with renal impairment for toxicity since Azacitidine and its metabolites are primarily excreted by the kidneys. Tumor Lysis Syndrome: Azacitidine may cause fatal or serious tumor lysis syndrome, including in patients with MDS. Assess baseline risk and monitor and treat as appropriate. Embryo-Fetal Toxicity: Azacitidine can cause fetal harm. Advise female patients and male patients with female partners of reproductive potential of the potential risk to a fetus and to use effective contraception. Risks of Substitution with Other Azacitidine Products Due to substantial differences in the pharmacokinetic parameters, the recommended dose and schedule for Azacitidine for Injection are different from those of oral Azacitidine products. Treatment of patients using Azacitidine for Injection at the recommended dosage of oral Azacitidine may result in a fatal adverse reaction. Treatment of patients using oral Azacitidine at the doses recommended for Azacitidine may not be effective. Do not substitute Azacitidine for Injection for oral Azacitidine. Anemia, Neutropenia and Thrombocytopenia Azacitidine causes anemia, neutropenia and thrombocytopenia in adult patients with MDS. Monitor complete blood counts frequently for response and/or toxicity, at a minimum, prior to each dosing cycle. In adult patients with MDS, after administration of the recommended dosage for the first cycle, adjust dosage for subsequent cycles based on nadir counts and hematologic response. Pediatric use information is approved for Celgene Corporation's Vidaza (Azacitidine for injection). However, due to Celgene Corporation's marketing exclusivity rights, this drug product is not labeled with that information. Hepatotoxicity in Patients with Severe Pre-existing Hepatic Impairment Because Azacitidine is potentially hepatotoxic in patients with severe pre-existing hepatic impairment, caution is needed in patients with liver disease. Patients with extensive tumor burden due to metastatic disease have been reported to experience progressive hepatic coma and death during Azacitidine treatment, especially in such patients with baseline albumin <30 g/L. Azacitidine is contraindicated in patients with advanced malignant hepatic tumors. Monitor liver chemistries prior to initiation of therapy and with each cycle. Safety and effectiveness of Azacitidine in patients with MDS and hepatic impairment have not been studied as these patients were excluded from the clinical trials.

Most common adverse reactions (>30%) in adult patients with MDS by subcutaneous route are: nausea, anemia, thrombocytopenia, vomiting, pyrexia, leukopenia, diarrhea, injection site erythema, constipation, neutropenia and ecchymosis. Most common adverse reactions by intravenous route also included petechiae, rigors, weakness and hypokalemia. The following adverse reactions are described in other labeling sections: Anemia, Neutropenia and Thrombocytopenia Hepatotoxicity in Patients with Severe Pre-existing Hepatic Impairment Renal Toxicity Tumor Lysis Syndrome Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. MDS The data described below reflect exposure to Azacitidine in 443 patients with MDS from 4 clinical studies. Study 1 was a supportive-care controlled trial (subcutaneous administration), Studies 2 and 3 were single arm studies (one with subcutaneous administration and one with intravenous administration), and Study 4 was an international randomized trial (subcutaneous administration). In Studies 1, 2 and 3, a total of 268 patients were exposed to Azacitidine, including 116 exposed for 6 cycles (approximately 6 months) or more and 60 exposed for greater than 12 cycles (approximately one year). Azacitidine was studied primarily in supportive-care controlled and uncontrolled trials (n=150 and n=118, respectively). The population in the subcutaneous studies (n=220) was 23 to 92 years old (mean 66.4 years), 68% male, and 94% white, and had MDS or AML. The population in the intravenous study (n=48) was 35 to 81 years old (mean 63.1 years), 65% male, and 100% white. Most patients received average daily doses between 50 and 100 mg/m 2. In Study 4, a total of 175 patients with higher-risk MDS (primarily RAEB and RAEB-T subtypes) were exposed to Azacitidine. Of these patients, 119 were exposed for 6 or more cycles, and 63 for at least 12 cycles. The mean age of this population was 68.1 years (ranging from 42 to 83 years), 74% were male, and 99% were white. Most patients received daily Azacitidine doses of 75 mg/m 2. Most Commonly Occurring Adverse Reactions (Subcutaneous or Intravenous Route) in Adult Patients with MDS: nausea, anemia, thrombocytopenia, vomiting, pyrexia, leukopenia, diarrhea, injection site erythema, constipation, neutropenia, ecchymosis.
