Regimen, "Pediatric-like GRAALL reinforced induction"

Study Evidence
Lepretre et al. 2015 (GRAALL-LYSA LL03) Phase II

Note: This regimen was meant for patients less than 60 years old (up to age 59). Regimen is as per the GRAALL-2003 Study with some minor differences. High-risk patients with an HLA sibling-matched donor or a fully matched (10/10) unrelated donor who achieved CR1 were offered allogeneic stem cell transplant.
