What was measured

To study whether intensifying induction, including fractionated cyclophosphamide and thioguanine, in patients with day 15 MRD ≥ 5% will result in improved leukemia cytoreduction in this subgroup compared to therapy followed in the TOTXV protocol.

Analysis population: The analysis will compare the proportion of TOTXV patients who had Day-19 MRD≥5% with the proportion of patients on TOTXVI with Day-15 MRD≥5%.
