**v. Recommended Dosage** Azacitidine treatment should be initiated and monitored under the supervision of a physician experienced in the use of chemotherapeutic agents. Patients should be premedicated with anti-emetics for nausea and vomiting. Posology The recommended starting dose for the first treatment cycle, for all patients regardless of baseline haematology laboratory values, is 75 mg/m2 of body surface area, injected subcutaneously, daily for 7 days, followed by a rest period of 21 days (28-day treatment cycle). It is recommended that patients be treated for a minimum of 6 cycles. Treatment should be continued as long as the patient continues to benefit or until disease progression. Patients should be monitored for haematologic response/toxicity and renal toxicities _(see section viii Warnings and Precautions_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _)_; a delay in starting the next cycle or a dose reduction as described below may be necessary. Laboratory tests Liver function tests, serum creatinine and serum bicarbonate should be determined prior to initiation of therapy and prior to each treatment cycle. Complete blood counts should be performed prior to initiation of therapy and as needed to monitor response and toxicity, but at a minimum, prior to each treatment cycle. _Dose adjustment due to haematological toxicity_ Haematological toxicity is defined as the lowest count reached in a given cycle (nadir) if platelets ≤ 50.0 x 109/l and/or absolute neutrophil count (ANC) ≤ 1 x 109/l. Recovery is defined as an increase of cell line(s) where haematological toxicity was observed of at least half of the difference of nadir and the baseline count plus the nadir count (i.e. blood count at recovery ≥ nadir Count + (0.5 x \[baseline count – nadir count\]). _Patients without reduced baseline blood counts (i.e. White Blood Cells (WBC) ≥ 3.0 x 109/l and ANC ≥ 1.5 x 109/l, and platelets ≥ 75.0 x 109/l) prior to the first treatment_ If haematological toxicity is observed following Azadine treatment, the next cycle of the therapy should be delayed until the platelet count and the ANC have recovered. If recovery is achieved within 14 days, no dose adjustment is necessary. However, if recovery has not been achieved within 14 days, the dose should be reduced according to the following table. Following dose modifications, the cycle duration should return to 28 days.  _Patients with reduced baseline blood counts (i.e. WBC < 3.0 x 109/l or ANC < 1.5 x 109/l or platelets < 75.0 x 109/l) prior to the first treatment_ Following Azacitidine treatment, if the decrease in WBC or ANC or platelets from that prior to treatment is ≤ 50 %, or greater than 50 % but with an improvement in any cell line differentiation, the next cycle should not be delayed and no dose adjustment made. If the decrease in WBC or ANC or platelets is greater than 50 % from that prior to treatment, with no improvement in cell line differentiation, the next cycle of Azacitidine therapy should be delayed until the platelet count and the ANC have recovered. If recovery is achieved within 14 days, no dose adjustment is necessary. However, if recovery has not been achieved within 14 days, bone marrow cellularity should be determined. If the bone marrow cellularity is > 50 %, no dose adjustments should be made. If bone marrow cellularity is ≤ 50 %, treatment should be delayed and the dose reduced according to the following table:  Following dose modifications, the cycle duration should return to 28 days. Special populations _Elderly patients_ No specific dose adjustments are recommended for the elderly. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function. _Renal impairment_ Azacitidine can be administered to patients with renal impairment without initial dose adjustment _(see section iii Pharmacokinetic Properties_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _)_. If unexplained reductions in serum bicarbonate levels to less than 20 mmol/l occur, the dose should be reduced by 50 % on the next cycle. If unexplained elevations in serum creatinine or blood urea nitrogen (BUN) to ≥ 2-fold above baseline values and above upper limit of normal (ULN) occur, the next cycle should be delayed until values return to normal or baseline and the dose should be reduced by 50 % on the next treatment cycle _(see section viii Warnings and Precautions_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _)_. _Hepatic impairment_ No formal studies have been conducted in patients with hepatic impairment _(see section viii Warnings and Precautions_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _)_. Patients with severe hepatic organ impairment should be carefully monitored for adverse events. No specific modification to the starting dose is recommended for patients with hepatic impairment prior to starting treatment; subsequent dose modifications should be based on haematology laboratory values. Azadine is contraindicated in patients with advanced malignant hepatic tumours _(see sections vii Contraindications and section viii Warnings and Precautions_ – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_ _)_. _Paediatric population_ The safety and efficacy of Azacitidine in children aged 0–17 years have not yet been established.
