Patients with Renal or Severe Hepatic Impairment Treatment with decitabine has not been studied in patients with pre-existing renal or hepatic impairment. For patients with pre-existing renal or hepatic impairment, consider the potential risks and benefits before initiating treatment with Decitabine for Injection. 2.2 Dosage Modifications for Adverse Reactions Hematologic Toxicity If hematologic recovery from a previous treatment cycle requires more than 6 weeks, delay the next cycle and reduce the dose temporarily by following this algorithm: Recovery requiring more than 6, but less than 8 weeks: delay dosing for up to 2 weeks and reduce the dose of Decitabine for Injection temporarily to 11 mg/m 2 every 8 hours (33 mg/m 2 /day, 99 mg/m 2 /cycle) upon restarting therapy. Recovery requiring more than 8, but less than 10 weeks: Perform bone marrow aspirate to assess for disease progression. In the absence of progression, delay dosing up to 2 more weeks and reduce the dose to 11 mg/m 2 every 8 hours (33 mg/m 2 /day, 99 mg/m 2 /cycle) upon restarting therapy, then maintain or increase dose in subsequent cycles as clinically indicated. Non-hematologic Toxicity Delay subsequent treatment for any the following non-hematologic toxicities and do not restart until toxicities resolve: Serum creatinine greater than or equal to 2 mg/dL Alanine transaminase (ALT), total bilirubin greater than or equal to 2 times upper limit of normal (ULN) Active or uncontrolled infection 2.3 Preparation and Administration Decitabine for Injection is a cytotoxic drug. Follow special handling and disposal procedures. 1 Aseptically reconstitute Decitabine for Injection with room temperature (20°C to 25°C) 10 mL of diluent for Decitabine for Injection. Upon reconstitution, the final concentration of the reconstituted decitabine solution is 5 mg/mL. Dilute the reconstituted solution with 0.9% Sodium Chloride Injection or 5% Dextrose Injection prior to administration. Temperature of the diluent (0.9% Sodium Chloride Injection or 5% Dextrose Injection) depends on time of administration after preparation. For Administration Within 15 Minutes of Preparation If Decitabine for Injection is intended to be administered within 15 minutes from the time of preparation, dilute the reconstituted solution with room temperature (20°C to 25°C) 0.9% Sodium Chloride Injection or 5% Dextrose Injection to a final concentration of 0.1 mg/mL to 1 mg/mL. Discard unused portion. For Delayed Administration If Decitabine for Injection is intended to be administered after 15 minutes of preparation, dilute the reconstituted solution with cold (2°C to 8°C) 0.9% Sodium Chloride Injection or 5% Dextrose Injection to a final concentration of 0.1 mg/mL to 1 mg/mL. Store at 2°C to 8°C for up to 7 hours. Diluted stored solution must be used within 7 hours from the time of preparation. Use the diluted, refrigerated solution within 7 hours from the time of preparation or discard. Discard unused portion. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Warnings and precautions
Neutropenia and Thrombocytopenia: Perform complete blood counts and platelet counts. (5.1) Embryo-Fetal Toxicity : Can cause fetal harm. Advise patients of reproductive potential of the potential risk to a fetus and to use effective contraception (5.2, 8.1, 8.3) 5.1 Myelosuppression Fatal and serious myelosuppression occurs in Decitabine for Injection-treated patients. Myelosuppression (anemia, neutropenia, and thrombocytopenia) is the most frequent cause of dose reduction, delay, and discontinuation. Neutropenia of any grade occurred in 90% of decitabine-treated patients with grade 3 or 4 occurring in 87% of patients. Grade 3 or 4 febrile neutropenia occurred in 23% of patients. Thrombocytopenia of any grade occurred in 89% of patients with grade 3 or 4 occurring in 85% of patients. Anemia of any grade occurred in 82% of patients. Perform complete blood count with platelets at baseline, prior to each cycle, and as needed to monitor response and toxicity. Manage toxicity using dose-delay, dose-reduction, growth factors, and anti-infective therapies as needed [see Dosage and Administration (2.2)] . Myelosuppression and worsening neutropenia may occur more frequently in the first or second treatment cycles and may not necessarily indicate progression of underlying MDS. 5.2 Embryo-Fetal Toxicity Based on findings from human data, animal studies and its mechanism of action, Decitabine for Injection can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) and Nonclinical Toxicology (13.1)] . In preclinical studies in mice and rats, decitabine caused adverse developmental outcomes including embryo-fetal lethality and malformations. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception while receiving Decitabine for Injection and for 6 months following the last dose. Advise males with female partners of reproductive potential to use effective contraception while receiving treatment with Decitabine for Injection and for 3 months following the last dose [see Use in Specific Populations (8.1, 8.3)].
Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Myelosuppression [see Warnings and Precautions (5.1)] Most common adverse reactions (> 50%) are neutropenia, thrombocytopenia, anemia, and pyrexia. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Sun Pharmaceutical Industries, Inc. at 1-800-818-4555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 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. The safety of decitabine was studied in 3 single-arm studies (N = 66, N = 98, N = 99) and 1 controlled supportive care study (N = 83 decitabine, N = 81 supportive care). The data described below reflect exposure to decitabine in 83 patients in the MDS trial. In the trial, patients received 15 mg/m 2 intravenously every 8 hours for 3 days every 6 weeks. The median number of cycles was 3 (range 0 to 9). Most Common Adverse Reactions: neutropenia, thrombocytopenia, anemia, fatigue, pyrexia, nausea, cough, petechiae, constipation, diarrhea, and hyperglycemia. Adverse Reactions Most Frequently (≥ 1%) Resulting in Clinical Intervention and or Dose Modification in the Controlled Supportive Care Study in the Decitabine Arm: Discontinuation: thrombocytopenia, neutropenia, pneumonia, Mycobacterium avium complex infection, cardio-respiratory arrest, increased blood bilirubin, intracranial hemorrhage, abnormal liver function tests. Dose Delayed: neutropenia, pulmonary edema, atrial fibrillation, central line infection, febrile neutropenia. Dose Reduced: neutropenia, thrombocytopenia, anemia, lethargy, edema, tachycardia, depression, pharyngitis. Table 1 presents all adverse reactions occurring in at least 5% of patients in the decitabine group and at a rate greater than supportive care.

Drug interactions
Drug interaction studies with decitabine have not been conducted. In vitro studies in human liver microsomes suggest that decitabine is unlikely to inhibit or induce cytochrome P450 enzymes. In vitro metabolism studies have suggested that decitabine is not a substrate for human liver cytochrome P450 enzymes. As plasma protein binding of decitabine is negligible (<1%), interactions due to displacement of more highly protein bound drugs from plasma proteins are not expected.
Use in specific populations
Lactation: Advise not to breastfeed. (8.2) 8.1 Pregnancy Risk Summary Based on findings from human data, animal studies, and the mechanism of action, Decitabine for Injection can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) and Nonclinical Toxicology (13.1)] . Limited published data on decitabine use throughout the first trimester during pregnancy describe adverse developmental outcomes including major birth defects (structural abnormalities). In animal reproduction studies, administration of decitabine to pregnant mice and rats during organogenesis caused adverse developmental outcomes including malformations and embryo-fetal lethality starting at doses approximately 7% of the recommended human dose on a mg/m 2 basis (see Data) . Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The estimated background risk of major birth defects and miscarriage in the U.S. general population is 2% to 4% and 15% to 20% of clinically recognized pregnancies, respectively. Data Human Data A single published case report of decitabine pregnancy exposure in a 39-year old woman with a hematologic malignancy described multiple structural abnormalities after 6 cycles of therapy in the 18th week of gestation. These abnormalities included holoprosencephaly, absence of nasal bone, mid-facial deformity, cleft lip and palate, polydactyly and rocker-bottom feet. The pregnancy was terminated. Animal Data In utero exposure to decitabine causes temporal related defects in the rat and/or mouse, which include growth suppression, exencephaly, defective skull bones, rib/sternabrae defects, phocomelia, digit defects, micrognathia, gastroschisis, micromelia. Decitabine inhibits proliferation and increases apoptosis of neural progenitor cells of the fetal CNS and induces palatal clefting in the developing murine fetus. Studies in mice have also shown that decitabine administration during osteoblastogenesis (day 10 of gestation) induces bone loss in offspring. In mice exposed to single IP (intraperitoneal) injections (0, 0.9 and 3.0 mg/m 2 , approximately 2% and 7% of the recommended daily clinical dose, respectively) over gestation days 8, 9, 10 or 11, no maternal toxicity was observed but reduced fetal survival was observed after treatment at 3 mg/m 2 and decreased fetal weight was observed at both dose levels. The 3 mg/m 2 dose elicited characteristic fetal defects for each treatment day, including supernumerary ribs (both dose levels), fused vertebrae and ribs, cleft palate, vertebral defects, hind-limb defects and digital defects of fore- and hind-limbs. In rats given a single IP injection of 2.4, 3.6 or 6 mg/m 2 (approximately 5%, 8%, or 13% the daily recommended clinical dose, respectively) on gestation days 9 to 12, no maternal toxicity was observed. No live fetuses were seen at any dose when decitabine was injected on gestation day 9. A significant decrease in fetal survival and reduced fetal weight at doses greater than 3.6 mg/m 2 was seen when decitabine was given on gestation day 10. Increased incidences of vertebral and rib anomalies were seen at all dose levels, and induction of exophthalmia, exencephaly, and cleft palate were observed at 6.0 mg/m 2 . Increased incidence of foredigit defects was seen in fetuses at doses greater than 3.6 mg/m 2 . Reduced size and ossification of long bones of the fore-limb and hind-limb were noted at 6.0 mg/m 2 . The effect of decitabine on postnatal development and reproductive capacity was evaluated in mice administered a single 3 mg/m 2 IP injection (approximately 7% the recommended daily clinical dose) on day 10 of gestation. Body weights of males and females exposed in utero to decitabine were significantly reduced relative to controls at all postnatal time points. No consistent effect on fertility was seen when female mice exposed in utero were mated to untreated males. Untreated females mated to males exposed in utero showed decreased fertility at 3 and 5 months of age (36% and 0% pregnancy rate, respectively). Follow up studies indicated that treatment of pregnant mice with decitabine on gestation day 10 was associated with a reduced pregnancy rate resulting from effects on sperm production in the F1-generation. 8.2 Lactation Risk Summary There are no data on the presence of decitabine or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions from decitabine in a breastfed child, advise women not to breastfeed while receiving Decitabine for Injection and for at least 2 weeks after the last dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Conduct pregnancy testing of females of reproductive potential prior to initiating Decitabine for njection. ContraceptionI Females Decitabine for Injection can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception while receiving Decitabine for Injection and for 6 months following the last dose. Males Advise males with female partners of reproductive potential to use effective contraception while receiving treatment with Decitabine for Injection and for 3 months following the last dose [see Nonclinical Toxicology (13.1)] . Infertility Based on findings of decitabine in animals, male fertility may be compromised by treatment with decitabine. The reversibility of the effect on fertility is unknown [see Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use The safety and effectiveness of Decitabine for Injection in pediatric patients have not been established.

Pediatric use
8.4 Pediatric Use The safety and effectiveness of Decitabine for Injection in pediatric patients have not been established.
Geriatric use
8.5 Geriatric Use Of the total number of patients exposed to decitabine in the controlled clinical trial, 61 of 83 patients were age 65 years and over, while 21 of 83 patients were age 75 years and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
Overdosage
There is no known antidote for overdosage with decitabine. Higher doses are associated with increased myelosuppression including prolonged neutropenia and thrombocytopenia. Standard supportive measures should be taken in the event of an overdose.

Mechanism of action
12.1 Mechanism of Action Decitabine is believed to exert its antineoplastic effects after phosphorylation and direct incorporation into DNA and inhibition of DNA methyltransferase, causing hypomethylation of DNA and cellular differentiation or apoptosis. Decitabine inhibits DNA methylation in vitro, which is achieved at concentrations that do not cause major suppression of DNA synthesis. Decitabine-induced hypomethylation in neoplastic cells may restore normal function to genes that are critical for the control of cellular differentiation and proliferation. In rapidly dividing cells, the cytotoxicity of decitabine may also be attributed to the formation of covalent adducts between DNA methyltransferase and decitabine incorporated into DNA. Non-proliferating cells are relatively insensitive to decitabine.
