Dosages

Newly diagnosed, resistant or intolerant Ph+ CML in the chronic phase; Ph+ ALL
  • Oral
    • 1 year up to 18 years
      [1] [2] [3] [4]

      • The dosage and dosing frequency of oncological agents depend on the condition and are very much subject to new insights. Oncological drugs are often used in combinations. For this reason, please refer to the detailed (national) treatment protocols:

        The following indicative dosages have been stated in the SmPC:

        Body weight Dose (SUSPENSION) Dose (TABLETS)
        5 to 10 kg 40 mg/day in 1 dose use suspensie 
        10 to 20 kg 60 mg/day in 1 dose 40 mg/day in 1 dose
        20 to 30 kg 90 mg/day in 1 dose 60 mg/day in 1 dose
        30 to 45 kg 105 mg/day in 1 dose 70 mg/day in 1 dose
        ≥ 45 kg 120 mg/day in 1 dose 100 mg/day in 1 dose

        The dose should be adjusted based on clinical response and toxicity (see SmPC)

        Treatment by or after consultations with a paediatric specialist (oncologist) who has experience using dasatinib for this indication.
Resistant/intolerant/recurrent CML in accelerated or blast phase
  • Oral
    • Tablet
      • 1 year up to 18 years
        [1] [2] [3]

        • The dosage and dosing frequency of oncological agents depend on the condition and are very much subject to new insights. Oncological drugs are often used in combinations. For this reason, please refer to the detailed national treatment protocols 

          The following indicative dosages have been stated in the literature:
          - 80 mg/m²/day in a single dose, max 180 mg/dose.
          In cases of toxicity, lower the dosage to 65 mg/m², max 110 mg/dose. If necessary, lower it further to 50 mg/m², max 80 mg/dose.

          Treatment by or after consultations with a paediatric specialist (oncologist) who has experience using dasatinib for this indication.
CAUTION:
  • Route of administration not applicable
    • 0 years up to 18 years

      • Please note that the tablets and suspension are NOT bioequivalent and therefore not directly interchangeable. They each have their own dosage regimen.

Renal impaiment in children > 3 months

The dose does not need to be adjusted for renal function disorders.

 

Patients on dialysis

No generalized recommendations are given.

Side effects in children

Common (1-10%): in Ph+ CML in the chronic phase delayed fusion of the epiphyses, growth retardation and sometimes (0.1-1%) in Ph+ ALL osteopenia. Otherwise, the safety profile is generally similar to that of adults.[SmPC]

Growth retardation [Hobernicht 2011, 8. Watanabe 2013]

Contra-indications

No information available on specific contra indications in children.

Warnings & precautions in children

Check the total blood count regularly after starting the therapy (once every 1-2 weeks).
Consider TDM if side effects occur.

Growth retardation in children: has been reported. It is therefore recommended to monitor growth and bone development in children.
