Official Title

Phase II/III Randomized Study to Improve Overall Survival in 18 to 60 Year-old Patients, Comparing Daunorubicin Versus High Dose Idarubicin Induction Regimens, High Dose Versus Intermediate Dose Cytarabine Consolidation Regimens, and Standard Versus Mycophenolate Mofetil Prophylaxis of Graft Versus Host Disease in Allografted Patients in First CR : a Backbone InterGroup-1 Trial

Brief Summary

This open label, multicenter phase II/III study with multiple randomization phases at differents stages of AML treatment (induction, consolidation and HSCT where applicable) is designed to improve OS in younger (18 to 60 year-old) patients, with AML risk-adapted patient strategies. Within the intermediate risk AML group, optimal GvHD prophylaxis following allogeneic SCT in first CR, after either myeloablative (MAC) or reduced intensity (RIC) conditioning, will also be evaluated. With an adaptative design, this clinical trial could test up to 3 novel AML agents of interest.

• Acute Myeloid Leukemia (AML)

• Idarubicin
• Daunorubicin
• HD Cytarabine
• Cyclosporine
• Methotrexate
• Mycophenolic acid (MPA)
• vosaroxin
• ID cytarabine
• Dexamethasone
• Venetoclax
