Trial to Test the Effects of Adding 1 of 2 New Treatment Agents to Commonly Used Chemotherapy Combinations

Summary

The AML18 Trial will evaluate several relevant therapeutic questions in Acute Myeloid Leukaemia (AML), as defined by the WHO, and High Risk Myelodysplastic Syndrome. The trial is primarily designed for patients over 60 years considered fit for an intensive chemotherapeutic approach, but younger patients who may not be considered suitable for the concurrent NCRI AML Trial for younger patients may also enter. Patients for whom intensive chemotherapy is not thought suitable may enter the concurrent NCRI trial of less intensive therapy (LI1). Approximately 1600 patients will be recruited. At entry, a randomisation will compare a standard chemotherapy schedule DA (Daunorubicin/Ara-C) combined with 1 dose of Mylotarg (gemtuzumab ozogamicin, or GO) in course 1 against CPX-351. Patients who have known adverse risk cytogenetics (using Grimwade 2010 classification favourable/intermediate/adverse) at diagnosis may enter a Phase 2 evaluation of the combination of Vosaroxin plus Decitabine. Patients who achieve complete remission (CR) and who are MRD negative by flow cytometry after course one of DA will receive one further course of DA, with a randomisation to receive, either a course of DA or intermediate dose Cytarabine (IDAC) as a third course. Patients who are MRD negative by flow cytometry after course one of CPX-351 will receive up to 2 further course of CPX. Patients who fail to achieve a CR after course 1 of DA or who are MRD positive by flow cytometry or for whom MRD information is not available, are eligible to be randomised to compare DA with DA plus Cladribine (DAC) or FLAG-Ida for up to two courses of therapy. Patients who fail to achieve a CR after course 1 of CPX-351 or who are MRD positive by flow cytometry or for whom MRD information is not available are eligible to be randomised between a second course of standard dose CPX versus a repeat of the course 1 schedule. Patients receiving Vosaroxin and Decitabine are excluded from these post course 1 randomisations . Following the outcome of course 1, patients who received DA chemotherapy on course 1 will be randomised to receive further chemotherapy with the 2nd generation FLT3 inhibitor AC220. Patients randomised to AC220 will be allocated a maximum of 3 courses (short AC220) or 3 courses plus maintenance for 1 year (long AC220). Patients receiving Vosaroxin and Decitabine are excluded from this randomisation. Patients will be eligible for a non-intensive allogeneic stem cell transplant if a suitable HLA matched donor is available.
