DOSAGE FORMS & STRENGTHS SECTION.

3 DOSAGE FORMS AND STRENGTHS. For Injection: 50 mg of decitabine as sterile, white to almost white lyophilized powder in single-dose vial for reconstitution.. For Injection: 50 mg of decitabine as lyophilized powder in single-dose vial for reconstitution. (3).

DRUG INTERACTIONS SECTION.

7 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 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.

FEMALES & MALES OF REPRODUCTIVE POTENTIAL SECTION.

8.3 Females and Males of Reproductive Potential. Pregnancy TestingConduct pregnancy testing of females of reproductive potential prior to initiating Decitabine for injection. ContraceptionFemalesDecitabine for injection can cause fetal harm when administered to pregnant women see Use in Specific Populations 8.1 )].

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis and Impairment of Fertility. Carcinogenicity studies with decitabine have not been conducted.The mutagenic potential of decitabine was tested in several in vitro and in vivo systems. Decitabine increased mutation frequency in L5178Y mouse lymphoma cells, and mutations were produced in an Escherichia coli lac-I transgene in colonic DNA of decitabine-treated mice. Decitabine caused chromosomal rearrangements in larvae of fruit flies. In male mice given IP injections of 0.15, 0.3 or 0.45 mg/m decitabine (approximately 0.3% to 1% the recommended clinical dose) times week for weeks, decitabine did not affect survival, body weight gain or hematological measures (hemoglobin and white blood cell counts). Testes weights were reduced, abnormal histology was observed and significant decreases in sperm number were found at doses >=0.3 mg/m 2. In females mated to males dosed with >= 0.3 mg/m decitabine, pregnancy rate was reduced and preimplantation loss was significantly increased.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 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. 12.2 Pharmacodynamics. Decitabine has been shown to induce hypomethylation both in vitro and in vivo. However, there have been no studies of decitabine-induced hypomethylation and pharmacokinetic parameters. 12.3 Pharmacokinetics. Pharmacokinetic (PK) parameters were evaluated in patients. Eleven patients received 20 mg/m infused over hour intravenously (treatment Option 2). Fourteen patients received 15 mg/m infused over hours intravenously treatment Option 1). PK parameters are shown in Table 3. Plasma concentration-time profiles after discontinuation of infusion showed biexponential decline. The clearance (CL) of decitabine was higher following treatment Option 2. Upon repeat doses, there was no systemic accumulation of decitabine or any changes in PK parameters. Population PK analysis (N=35) showed that the cumulative AUC per cycle for treatment Option was 2.3-fold lower than the cumulative AUC per cycle following treatment Option 1. Table Mean (CV% or 95% CI) Pharmacokinetic Parameters of Decitabine N=14, +N=11, N=35 Cumulative AUC per cycle Dose max AUC 0- 1/2 (h)CL AUC Cumulative (ng/mL) (ngh/mL) (L/h/m 2) (ngh/mL)15 mg/m 3-hr infusion every hours for days (Option 1) 73.81630.621251332(66)(62)(49)(53)(1010-1730)20 mg/m 1-hr infusion daily for days (Option 2) 1471150.54210570 (49) (43)(43)(47)(470-700)The exact route of elimination and metabolic fate of decitabine is not known in humans. One of the pathways of elimination of decitabine appears to be deamination by cytidine deaminase found principally in the liver but also in granulocytes, intestinal epithelium and whole blood.Specific PopulationsPatients with Renal ImpairmentThere are no data on the use of Decitabine for injection in patients with renal impairment.Patients with Hepatic ImpairmentThere are no data on the use of Decitabine for injection in patients with hepatic impairment.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Controlled Trial in Myelodysplastic Syndrome. randomized open-label, multicenter, controlled trial evaluated 170 adult patients with myelodysplastic syndromes (MDS) meeting French-American-British (FAB) classification criteria and International Prognostic Scoring System (IPSS) High-Risk, Intermediate-2 and Intermediate-1 prognostic scores. Eighty-nine patients were randomized to Decitabine for injection therapy plus supportive care (only 83 received Decitabine for injection), and 81 to Supportive Care (SC) alone. Patients with Acute Myeloid Leukemia (AML) were not intended to be included. Of the 170 patients included in the study, independent review (adjudicated diagnosis) found that 12 patients (9 in the Decitabine for injection arm and in the SC arm) had the diagnosis of AML at baseline. Baseline demographics and other patient characteristics in the Intent-to-Treat (ITT) population were similar between the groups, as shown in Table 4.Table Baseline Demographics and Other Patient Characteristics (ITT) Demographic or Other Patient CharacteristicDecitabine for injectionN 89 Supportive CareN= 81 Age (years) Mean (+-SD)69+-10 67+-10Median (IQR)70 (65-76) 70 (62-74) (Range: min-max) (31-85)(30-82) Sex (%) Male 59 (66) 57 (70) Female30 (34)24 (30) Race (%) White83 (93) 76 (94) Black4 (4)2 (2)Other2 (2)3 (4)Weeks Since MDS Diagnosis Mean (+-SD) 86+-13177+-119Median (IQR)29 (10-87)35 (7-98)(Range: min-max) (2-667)(2-865) Previous MDS Therapy (%)Yes27 (30) 19 (23)No62 (70) 62 (77)RBC Transfusion Status (%)Independent23 (26) 27 (33) Dependent66 (74) 54 (67)Platelet Transfusion Status (%)Independent69 (78)62 (77)Dependent20 (22)19 (23) IPSS Classification (%)Intermediate-128 (31) 24 (30)Intermediate-238 (43) 36 (44) High Risk23 (26)21 (26) FAB Classification (%)RA12 (13) 12 (15)RARS7 (8) (5)RAEB47 (53)43 (53) RAEB-t17 (19)14 (17) CMML6 (7)8 (10)Patients randomized to the Decitabine for injection arm received Decitabine for injection intravenously infused at dose of 15 mg/m over 3-hour period, every hours, for consecutive days. This cycle was repeated every weeks, depending on the patients clinical response and toxicity. Supportive care consisted of blood and blood product transfusions, prophylactic antibiotics, and hematopoietic growth factors. The study endpoints were overall response rate (complete response partial response) and time to AML or death. Responses were classified using the MDS International Working Group (IWG) criteria; patients were required to be RBC and platelet transfusion independent during the time of response. Response criteria are given in Table 5. Table Response Criteria for the Controlled Trial in MDS Cheson BD, Bennett JM, et al.

The median duration of response (range) for patients who responded to Decitabine for injection was 288 days (116-388) and median time to response (range) was 93 days (55-272). All but one of the Decitabine for injection-treated patients who responded did so by the fourth cycle. Benefit was seen in an additional 13% of Decitabine for injection-treated patients who had hematologic improvement, defined as response less than PR lasting at least weeks, compared to 7% of SC patients. Decitabine for injection treatment did not significantly delay the median time to AML or death versus supportive care.Table Analysis of Response (ITT)p-value <0.001 from two-sided Fishers Exact Test comparing Decitabine for injection vs. Supportive Care. +In the statistical analysis plan, p-value of 0.024 was required to achieve statistical significance.

MECHANISM OF ACTION SECTION.

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.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis and Impairment of Fertility. Carcinogenicity studies with decitabine have not been conducted.The mutagenic potential of decitabine was tested in several in vitro and in vivo systems. Decitabine increased mutation frequency in L5178Y mouse lymphoma cells, and mutations were produced in an Escherichia coli lac-I transgene in colonic DNA of decitabine-treated mice. Decitabine caused chromosomal rearrangements in larvae of fruit flies. In male mice given IP injections of 0.15, 0.3 or 0.45 mg/m decitabine (approximately 0.3% to 1% the recommended clinical dose) times week for weeks, decitabine did not affect survival, body weight gain or hematological measures (hemoglobin and white blood cell counts). Testes weights were reduced, abnormal histology was observed and significant decreases in sperm number were found at doses >=0.3 mg/m 2. In females mated to males dosed with >= 0.3 mg/m decitabine, pregnancy rate was reduced and preimplantation loss was significantly increased.

OVERDOSAGE SECTION.

10 OVERDOSAGE. There is no known antidote for overdosage with Decitabine for injection. Higher doses are associated with increased myelosuppression including prolonged neutropenia and thrombocytopenia. Standard supportive measures should be taken in the event of an overdose.

8.4 Pediatric Use. The safety and effectiveness of Decitabine for injection in pediatric patients have not been established.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Decitabine has been shown to induce hypomethylation both in vitro and in vivo. However, there have been no studies of decitabine-induced hypomethylation and pharmacokinetic parameters.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Pharmacokinetic (PK) parameters were evaluated in patients. Eleven patients received 20 mg/m infused over hour intravenously (treatment Option 2). Fourteen patients received 15 mg/m infused over hours intravenously treatment Option 1). PK parameters are shown in Table 3. Plasma concentration-time profiles after discontinuation of infusion showed biexponential decline. The clearance (CL) of decitabine was higher following treatment Option 2. Upon repeat doses, there was no systemic accumulation of decitabine or any changes in PK parameters. Population PK analysis (N=35) showed that the cumulative AUC per cycle for treatment Option was 2.3-fold lower than the cumulative AUC per cycle following treatment Option 1. Table Mean (CV% or 95% CI) Pharmacokinetic Parameters of Decitabine N=14, +N=11, N=35 Cumulative AUC per cycle Dose max AUC 0- 1/2 (h)CL AUC Cumulative (ng/mL) (ngh/mL) (L/h/m 2) (ngh/mL)15 mg/m 3-hr infusion every hours for days (Option 1) 73.81630.621251332(66)(62)(49)(53)(1010-1730)20 mg/m 1-hr infusion daily for days (Option 2) 1471150.54210570 (49) (43)(43)(47)(470-700)The exact route of elimination and metabolic fate of decitabine is not known in humans. One of the pathways of elimination of decitabine appears to be deamination by cytidine deaminase found principally in the liver but also in granulocytes, intestinal epithelium and whole blood.Specific PopulationsPatients with Renal ImpairmentThere are no data on the use of Decitabine for injection in patients with renal impairment.Patients with Hepatic ImpairmentThere are no data on the use of Decitabine for injection in patients with hepatic impairment.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryBased on findings from human data, animal studies, and the mechanism of action, Decitabine for injection can cause fetal harm when administered to pregnant woman. see Clinical Pharmacology (12.1) and Nonclinical Toxicology 13.1 )]. Limited published data on Decitabine for injection 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 mg/m basis (see Data). Advise pregnant women of the potential risk to fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have 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.DataHuman DataA single published case report of decitabine pregnancy exposure in 39-year old woman with hematologic malignancy described multiple structural abnormalities after cycles of therapy in the 18 th 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 mg/m and decreased fetal weight was observed at both dose levels. The mg/m 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 single IP injection of 2.4, 3.6 or mg/m (approximately 5%, 8%, or 13% the daily recommended clinical dose, respectively) on gestation days 9-12, no maternal toxicity was observed. No live fetuses were seen at any dose when decitabine was injected on gestation day 9. significant decrease in fetal survival and reduced fetal weight at doses greater than 3.6 mg/m 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 single mg/m 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 and 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 reduced pregnancy rate resulting from effects on sperm production in the F1-generation.

WARNINGS AND PRECAUTIONS SECTION.

5 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 fetus and to use effective contraception 5.2, 8.1, 8.3) 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 fetus and to use effective contraception 5.2, 8.1, 8.3) 5.1 Myelosuppression. Fatal and serious myelosupression occurs in Decitabine for injection-treated patients. Myelosuppression (anemia, neutropenia, and thrombocytopenia) is the most frequent cause of Decitabine for injection dose reduction, delay, and discontinuation. Neutropenia of any grade occurred in 90% of Decitabine for injection-treated patients with grade or occurring in 87% of patients. Grade or febrile neutropenia occurred in 23% of patients. Thrombocytopenia of any grade occurred in 89% of patients with grade or 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 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 fetus. Advise females of reproductive potential to use effective contraception while receiving Decitabine for injection and for 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 months following the last dose. see Use in Specific Populations 8.1, 8.3) ].
