Chronic myelogenous leukaemia (CML) Philadelphia chromosome positive (Ph+)

Active Ingredient: Dasatinib

Indication for Dasatinib

Population group: only adults (18 years old or older)

Dasatinib is indicated for the treatment of adult patients with:

  • newly diagnosed Philadelphia chromosome positive (Ph+) chronic myelogenous leukaemia (CML) in the chronic phase.
  • chronic, accelerated or blast phase CML with resistance or intolerance to prior therapy including imatinib.
  • Ph+ acute lymphoblastic leukaemia (ALL) and lymphoid blast CML with resistance or intolerance to prior therapy.

Dasatinib is indicated for the treatment of paediatric patients with:

  • newly diagnosed Ph+ CML in chronic phase (Ph+ CML-CP) or Ph+ CML-CP resistant or intolerant to prior therapy including imatinib.
  • newly diagnosed Ph+ ALL in combination with chemotherapy.

For this indication, competent medicine agencies globally authorize below treatments:

100-140 mg once daily

Route of admnistration

Oral

Defined daily dose

100 - 140 mg

Dosage regimen

From 100 To 140 mg once every day

Loading dose

100 mg

Detailed description

The recommended starting dose for chronic phase CML is 100 mg dasatinib once daily.

The recommended starting dose for accelerated, myeloid or lymphoid blast phase (advanced phase) CML or Ph+ ALL is 140 mg once daily.

Treatment duration

In clinical studies, treatment with dasatinib in adults with Ph+ CML-CP, accelerated, myeloid or lymphoid blast phase (advanced phase) CML, or Ph+ ALL and paediatric patients with Ph+ CML-CP was continued until disease progression or until no longer tolerated by the patient. The effect of stopping treatment on long-term disease outcome after the achievement of a cytogenetic or molecular response [including complete cytogenetic response (CCyR), major molecular response (MMR) and MR4.5] has not been investigated.

In clinical studies, treatment with dasatinib in paediatric patients with Ph+ ALL was administered continuously, added to successive blocks of backbone chemotherapy, for a maximum duration of two years. In patients that receive a subsequent stem cell transplantation, dasatinib can be administered for an additional year post-transplantation.

Dose escalation

In clinical studies in adult CML and Ph+ ALL patients, dose escalation to 140 mg once daily (chronic phase CML) or 180 mg once daily (advanced phase CML or Ph+ ALL) was allowed in patients who did not achieve a haematologic or cytogenetic response at the recommended starting dose.

The following dose escalations shown in the table are recommended in paediatric patients with Ph+ CML-CP who do not achieve a haematologic, cytogenetic and molecular response at the recommended time points, per current treatment guidelines, and who tolerate the treatment.

Dose escalation for paediatric patients with Ph+ CML-CP:

 Dose (maximum dose per day)
Starting dose Escalation
Tablets 40 mg 50 mg
60 mg 70 mg
70 mg 90 mg
100 mg 120 mg

Dose escalation is not recommended for paediatric patients with Ph+ ALL, as dasatinib is administered in combination with chemotherapy in these patients.

Dosage considerations

Dasatinib can be taken with or without a meal and should be taken consistently either in the morning or in the evening.

Active ingredient

Dasatinib

Dasatinib inhibits the activity of the BCR-ABL kinase and SRC family kinases along with a number of other selected oncogenic kinases including c-KIT, ephrin (EPH) receptor kinases, and PDGFβ receptor. Dasatinib is a potent, subnanomolar inhibitor of the BCR-ABL kinase with potency at concentration of 0.6-0.8 nM. It binds to both the inactive and active conformations of the BCR-ABL enzyme.
