Mye Child

About this trial

MyeChild 01 is an international phase III clinical trial in children with acute myeloid leukaemia (AML); a disease with significant mortality. It will compare two induction chemotherapy regimens: mitoxantrone and cytarabine (current standard treatment) with liposomal daunorubicin and cytarabine.

This will test liposomal daunorubicin, which is believed to be less cardiotoxic than similar conventional drugs, although this is unproven. Patients responding well to induction chemotherapy are eligible for a randomisation of two consolidation regimens: high dose cytarabine (current standard treatment) or fludarabine and cytarabine (FLA); a regimen commonly used in patients with relapsed disease, testing whether FLA is more effective in front line therapy than standard consolidation treatment.

Patients with cytogenetic features associated with a higher risk of relapse and those responding sub-optimally to induction treatment are candidates for haemopoietic stem cell transplant (HSCT) and are eligible for a randomisation comparing two HSCT conditioning regimens: myeloablative conditioning (MAC) (current UNited Kingdom (UK) standard) or reduced intensity conditioning (RIC).

HSCT has not consistently shown benefit in high risk patients because the mortality associated with the procedure has outweighed the advantage from a reduction in relapse risk. This will test whether reducing the intensity of conditioning improves survival by reducing transplant related deaths without increasing the relapse rate. The trial incorporates a dose finding study for gemtuzumab ozogamicin. The aim is to identify the optimum tolerated number of doses of gemtuzumab ozogamicin (up to a total of 3 doses), which can be safely combined with either of the induction chemotherapy regimens and then to compare this number of doses with one dose of gemtuzumab ozogamicin.

The intensity of treatment will be directed by cytogenetics/molecular genetics and response assessed by minimal residual disease (MRD) levels measured by flow cytometry and molecular methodology.
