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/mcL and platelets at least 50,000/mcL) for a minimum of 4 cycles.
A complete or partial response may take longer than 4 cycles. 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. 2 )] . Repeat cycles every 4 weeks upon hematologic recovery (ANC at least 1,000/mcL and platelets at least 50,000/mcL) 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 Dosage 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:
1 )] Most common adverse reactions (> 50%) are neutropenia, thrombocytopenia, anemia, and pyrexia. gov/medwatch. 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 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.

5 WARNINGS AND PRECAUTIONS Neutropenia and Thrombocytopenia : Perform complete blood counts and platelet counts. 1 ) Embryo-Fetal Toxicity : Can cause fetal harm. 1 Myelosuppression 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.
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.
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. 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. 3 )].

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.
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° 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 per mL. 9% Sodium Chloride Injection or 5% Dextrose Injection prior to administration. 9% Sodium Chloride Injection or 5% Dextrose Injection) depends on time of administration after preparation.
1 mg per mL to 1 mg per mL. Discard unused portion. 1 mg per mL to 1 mg per mL. Store at 2° to 8°C for up to 4 hours. Diluted stored solution must be used within 4 hours from the time of preparation. Discard unused portion. Use the diluted, refrigerated solution within 4 hours from the time of preparation or discard.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if there is evidence of particulate matter or discoloration.

2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of Decitabine for Injection. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
