Decitabine dosing information
Usual Adult Dose for Myelodysplastic Syndrome:
TREATMENT REGIMEN OPTION 1:
15 mg/m2 IV over 3 hours; repeat every 8 hours for 3 days; repeat this cycle every 6 weeks; patients may be premedicated with standard antiemetic therapy
If hematologic recovery (ANC 1,000/mcL or greater and platelets 50,000/mcL or greater) from a previous treatment cycle requires more than 6 weeks, then the next cycle should be delayed and dosing temporarily reduced by following this algorithm:
-Recovery requiring more than 6, but less than 8 weeks: Delay dosing for up to 2 weeks and temporarily reduce the dose to 11 mg/m2 IV every 8 hours (33 mg/m2/day, 99 mg/m2/cycle) when restarting therapy
-Recovery requiring more than 8, but less than 10 weeks: Assess patient for disease progression (by bone marrow aspirates); in the absence of progression, the dose should be delayed up to 2 more weeks and then reduced to 11 mg/m2 IV every 8 hours (33 mg/m2/day, 99 mg/m2/cycle) when restarting therapy, then maintained or increased in subsequent cycles as clinically indicated
TREATMENT REGIMEN OPTION 2:
20 mg/m2 IV over 1 hour; repeat daily for 5 days; repeat this cycle every 4 weeks; patients may be premedicated with standard antiemetic therapy
If myelosuppression is present, subsequent treatment cycles should be delayed until there is hematologic recovery (ANC 1,000/mcL or greater and platelets 50,000/mcL or greater)
-With either regimen, it is recommended that patients be treated for a minimum of 4 cycles; however, a complete or partial response may take longer than 4 cycles.
-Perform complete blood and platelet counts prior to each cycle and as needed to monitor response and toxicity.
-Perform liver chemistries and serum creatinine prior to initiation of therapy.
