🩺 Clinical
Decitabine is used to treat myelodysplastic syndrome (a group of conditions in which the bone marrow produces blood cells that are misshapen and does not produce enough healthy blood cells). Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow.

Decitabine For Injection is a nucleoside metabolic inhibitor indicated for treatment of adult patients with myelodysplastic syndromes (MDS) including previously treated and untreated, de novo and secondary MDS of all French-American-British subtypes (refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, and chronic myelomonocytic leukemia) and intermediate-1, intermediate2, and high-risk International Prognostic Scoring System groups
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION • Three Day Regimen : Administer decitabine for injection at a dose of 15 mg/m 2 by continuous intravenous infusion over 3 hours repeated every 8 hours for 3 days. Repeat cycle every 6 weeks. ( 2.1 ) • Five Day Regimen: Administer decitabine for injection at a dose of 20 mg/m by continuous intravenous infusion over 1 hour repeated daily for 5 days. Repeat cycle every 4 weeks ( 2.1 ) .
2.1Recommended Dosage Pre-Medications and Baseline Testing Consider pre-medicating for nausea with antiemetics. Conduct baseline laboratory testing: complete blood count (CBC) with platelets, serum hepatic panel, and serum creatinine. Decitabine for injection Regimen Options Three Day Regimen Administer decitabine for injection at a dose of 15 mg/m 2 by continuous intravenous infusion over 3 hours repeated every 8 hours for 3 days.
Repeat cycles every 6 weeks upon hematologic recovery (ANC at least 1,000/μL and platelets at least 50,000/μL) for a minimum of 4 cycles. A complete or partial response may take longer than 4 cycles. Delay and reduce dose for hematologic toxicity [ see Dosage and Administration ( 2.2 )].
Five Day Regimen Administer decitabine for injection at a dose of 20 mg/m 2 by continuous intravenous infusion over 1 hour daily for 5 days. Delay and reduce dose for hematologic toxicity [see Dosage and Administration ( 2.2 )]. Repeat cycles every 4 weeks upon hematologic recovery (ANC at least 1,000/μL and platelets at least 50,000/μL) for a minimum of 4 cycles.
A complete or partial response may take longer than 4 cycles. Patients with Renal or Severe Hepatic Impairment Treatment with decitabine for injection 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.
2.2Dosage Modifications for Adverse Reactions Hematologic Toxicity If hematologic recovery from a previous decitabine for injection treatment cycle requires more than 6 weeks, delay the next cycle of decitabine for injection therapy and reduce decitabine for injection dose temporarily by following this algorithm: Recovery requiring more than 6, but less than 8 weeks: delay decitabine for injection dosing for up to 2 weeks and reduce the dose 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 decitabine for injection dosing for 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 decitabine for injection treatment for any the following nonhematologic 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
2.3Preparation 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 Sterile Water for Injection, USP.
Upon reconstitution, the final concentration of the reconstituted decitabine for injection solution is 5 mg/mL. You must 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,…
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS For Injection: 50 mg of decitabine as a sterile, white to almost white lyophilized powder, in a single-dose vial for reconstitution. For Injection: 50 mg of decitabine as a lyophilized powder in a single-dose vial for reconstitution. ( 3 )

⚠️ Warnings and Cautions ▾
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 a fetus and to use effective contraception ( 5.2 , 8.1 , 8.3 )
5.1Myelosuppression Fatal and serious myelosuppression 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 3 or 4 occurring in 87% of patients.
Thrombocytopenia of any grade occurred in 89% of patients with grade 3 or 4 occurring in 85% of patients. Grade 3 or 4 febrile neutropenia occurred in 23% 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.
5.2Embryo-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 )].
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS 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 Dr. REDDY’S LABORATORIES Inc., at 1-888-375-3784 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical 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 for injection was studied in 3 single-arm studies (N=66, N=98, N=99) and 1 controlled supportive care study (N=83 decitabine for injection, N=81 supportive care). The data described below reflect exposure to decitabine for injection 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 decitabine for injection 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 for Injection 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 for injection group and at a rate greater than supportive care.

🔄 Drug Interactions ▾
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 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 ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. (8.2)
8.1Pregnancy 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 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 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 9-12, 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 co…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of decitabine for injection in pediatric patients have not been established
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of patients exposed to decitabine for injection 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 ▾
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.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism 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.
12.2Pharmacodynamics Decitabine has been shown to induce hypomethylation both in vitro and in vivo. However, there have been no studies of decitabineinduced hypomethylation and pharmacokinetic parameters.
12.3Pharmacokinetics Pharmacokinetic (PK) parameters were evaluated in patients. Eleven patients received 20 mg/m 2 infused over 1 hour intravenously (treatment Option 2). Fourteen patients received 15 mg/m 2 infused over 3 hours intravenously (treatment Option 1).
PK parameters are shown in Table 3. Plasma concentration-time profiles after discontinuation of infusion showed a 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 2 was 2.3-fold lower than the cumulative AUC per cycle following treatment Option 1.

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 Populations Patients with Renal Impairment There are no data on the use of decitabine for injection in patients with renal impairment. Patients with Hepatic Impairment There are no data on the use of decitabine for injection in patients with hepatic impairment.
🧬 Mechanism of Action ▾
12.1Mechanism 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.
