...72/79 enrolled pts. were evaluable for response, 3 withdrew consent, 4 did not meet eligibility criteria...Sixty-eight of 72 pts. (94.4%) achieved CR, one died during induction and one was refractory, 2 pts discontinued study therapy...EFS and OS at 4 years was 42%, and 47%, respectively...The proportion of pts. with a BCR-ABL1/ABL1 ratio ≤0.1% increased from 41% after induction to 86% after consolidation 2; that of pts. with undetectable or non quantifiable BCR-ABL1 transcripts (sensitivity ≥10-4) increased from 14% to 58%....Nilotinib combined with low intensity chemotherapy is well tolerated and highly effective in elderly pts. with Ph-positive ALL. OS and EFS compare favorably with previous similar studies testing imatinib or dasatinib.
