Idarubicin plus BuCy versus BuCy conditioning regimens for intermediate-risk acute myeloid leukemia in first complete remission undergoing auto-HSCT: An open-label, multicenter, randomized phase 3 trial. Am J Hematol 2023; 98:408-412. [PMID: 36588387 DOI: 10.1002/ajh.26800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 11/22/2022] [Accepted: 11/26/2022] [Indexed: 01/03/2023]
Abstract
We report a randomized prospective phase 3 study, designed to evaluate the efficacy and tolerability of idarubicin plus busulfan and cyclophosphamide (IDA-BuCy) versus BuCy in autologous hematopoietic stem-cell transplantation (auto-HSCT) for intermediate-risk acute myeloid leukemia (IR-AML) patients in first complete remission (CR1). One hundred and fifty-four patients were enrolled and randomized to receive IDA-BuCy (IDA 15 mg/m2/day on days -12 to -10, Bu 3.2 mg/kg/day on days -7 to -4, and Cy 60 mg/kg/day on days -3 to -2) or BuCy. The 2-year incidence of relapse was 15.6% and 19.5% in IDA-BuCy and BuCy groups (p = 0.482), respectively. There was no significant overall survival (OS) and disease-free survival (DFS) benefit for IR-AML patients receiving IDA-BuCy (2-year OS 81.8% in IDA-BuCy vs. 83.1% in BuCy, p = 0.798; 2-year DFS 76.6% in IDA-BuCy vs. 79.2% in BuCy, p = 0.693). Grade 3 or worse regimen-related toxicity (RRT) was reported for 22 (28.9%) of 76 and 9 (12.0%) of 75 patients in two groups (p = 0.015), respectively. AEs within 100 days with an outcome of death were reported for 4 (5.3%) and 0 patients in two groups. In conclusion, IDA-BuCy has higher RRT and similar anti-leukemic activity compared with BuCy in IR-AML patients in CR1 undergoing auto-HSCT. Thus, caution should be taken when choosing IDA-BuCy for IR-AML patients in CR1 with auto-HSCT. This trial is registered with ClinicalTrials.gov, NCT02671708, and is complete.

Comparison of outcomes of idarubicin intensified TBI-CY and traditional TBI-CY conditioning regimen for high-risk acute lymphoblastic leukemia undergoing allogeneic hematopoietic stem cell transplantation: A single center experience. Leuk Res 2015; 39:S0145-2126(15)30369-6. [PMID: 26340915 DOI: 10.1016/j.leukres.2015.08.015] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2015] [Revised: 08/19/2015] [Accepted: 08/25/2015] [Indexed: 10/23/2022]
Abstract
High-risk acute lymphoblastic leukemia (ALL) carries a very poor prognosis, even after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Exploring novel conditioning regimen to more effectively eliminate leukemic clone while not alter transplant-related mortality (TRM) has become focus of attention. We retrospectively evaluated outcomes of 87 high-risk ALL patients undergoing allo-HSCT: 47 patients received idarubicin (IDA) intensified TBI-CY and 40 patients received traditional TBI-CY regimen. In IDA intensified group, patients received TBI (8Gy) on day-8, IDA of 15mg/m2/d from day-6 to -5, followed by CY (60mg/kg/d) on day-3 to -2. The cumulative incidence of relapse was significantly lower in IDA intensified group compared with TBI-CY group (P=0.018). Oropharyngeal mucositis was observed more frequent in IDA intensified group (P=0.013), while not followed by increased TRM. Very high-risk ALL patients benefit from IDA intensified regimen with only two of eight patients in no remission (NR) pre-transplantation and two of twelve ph+ALL patients relapsed after transplantation. After a median follow-up for all survivors of 21 months (range, 12-53 months), 2-year estimated OS and DFS was 66.2% vs 45.3% (P=0.031) and 62.5% vs 43.5% (P=0.044), respectively. In conclusion, IDA intensified TBI-CY regimen may reduce relapse while not increasing TRM, providing better survival for high-risk ALL patients undergoing allo-HSCT.

Abstract
We conducted a retrospective study to evaluate the outcome of 94 consecutive patients with high-risk hematological malignancies who received allo-PBSCT, following idarubicin (IDA)-intensified BUCY2 (IDA-BUCY2) myeloablative conditioning regimens (n=53) and BUCY2 conditioning regimens (n=41). IDA 15 mg/m(2) once daily was administered by continuous infusion on days -11 to -9, followed by BU, 3.2 mg/kg in divided doses daily, on days -6 to -4, and i.v. injection of CY, 1.8 g/m(2) once daily on days -3 to -2 in the IDA-BUCY2 group. The relapse rate in patients in the IDA-BUCY2 and BUCY2-conditioning regimens group was 18.9 and 39%, respectively (P=0.030). There was no significant difference in terms of TRM. The cumulative probabilities of OS and disease-free survival at 2 years for patients conditioned with the IDA-BUCY2 and BUCY2 regimens were 65.3% vs 46.8% (P=0.038), and 63.5% vs 43.4% (P=0.025), respectively. Multivariate analysis showed that IDA-BUCY2 regimens and limited chronic GVHD were the only two factors resulting in improved survival and reduced relapse rate. This retrospective study suggests that IDA-intensified BUCY2 may be substituted for BUCY2 as conditioning regimen for patients with high-risk hematological malignancies.

Abstract
Aim: To analyze the results of idarubicin (IDA)- versus etoposide (VP16)-intensified myeloablative conditioning regimen in allogeneic hematopoietic stem cell transplantation (allo-SCT) for high-risk acute leukemia. Methods: From January 2005 to June 2008, 48 consecutive patients (male: n=29; median age: 30 years, range 14–51 years) with high-risk acute leukemia underwent allo-SCT following an IDA- or VP16-intensified conditioning regimen. The conditioning regimens were modified BUCY2 (busulfan+cyclophosphamide) consisting of IDA (15 mg/m2 per day, days -12 to -10) or VP16 (25 mg/kg per day, days -3 to -2) and CY/TBI (cyclophosphamide/total body irradiation) intensified with IDA (15 mg/m2 per day, days -6 to -5) or VP16 (25 mg/kg per day, days -3 to -2) for acute myeloid leukemia and acute lymphoblastic leukemia, respectively. Results: Between the two groups, no significant differences in terms of baseline characteristics, incidence of acute or chronic graft-versus-host disease (GVHD) or transplant-related mortality (TRM) (P=0.50) were observed. However, the IDA group demonstrated higher incidences of mucositis and Aspergillus pneumonia (P<0.01 and P=0.03, respectively). For the IDA and VP16 groups, relapse rates were 28% and 50%, respectively (P=0.13). For the same groups, the 2-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 72% versus 51% (P=0.04) and 74% versus 53% (P=0.04), respectively. Conclusion: This retrospective analysis suggests that conditioning regimens intensified with IDA can achieve better outcomes than conditioning regimens with VP16 in patients preparing to undergo allo-SCT for high-risk acute leukemia.

Abstract
Different studies have suggested the potential utility of autologous stem cell transplantation (ASCT) in acute myeloid leukaemia (AML) of the elderly with encouraging results in selected patients. However, while the introduction of peripheral blood stem cells (PBSC) has consistently reduced morbidity and mortality of the procedure, relapse still represents the major cause of ASCT failure. One possibility to ameliorate therapeutic results could rely on the adoption of conditioning regimens specifically designed for AML. We report therapeutic results from a series of 40 AML patients older than 60 years (median age 67 years) autografted in first complete remission (CR), after conditioning with continuous infusion (c.i.) high dose idarubicin and busulphan. Fourty patients (median age: 67 years) received 2 days c.i. idarubicin at 20 mg/m(2)/day, followed by 3 days oral or intravenous busulphan (4 mg/kg/day) as conditioning. No case of transplant-related mortality occurred. Cardiac toxicity was absent, while 31 patients (77%) had grade 3-4 mucositis. After a median follow-up of 25 months, median disease free and overall survival (OS) for the whole patient population were 13 and 22 months, respectively. Three patients died while in CR from causes unrelated to AML. Better results were achieved in patients with intermediate karyotype as opposed to those with adverse cytogenetics. Our data confirm the feasibility of a conditioning regimen based on high-dose idarubicin plus busulphan in older selected AML patients and suggest clinical improvement in patients with normal cytogenetics.

Abstract
There is growing interest in autologous stem cell transplantation (ASCT) for elderly patients with acute myeloid leukemia (AML). While mortality and toxicity from ASCT have been reduced, relapse rate is still high. In a prospective study, we investigated the feasibility of a new conditioning regimen consisting of high-dose idarubicin plus busulfan in AML patients aged over 60 years undergoing ASCT. A total of 14 patients (median age: 64 years) received 2 days continuous infusion of idarubicin at 20 mg/m2/day, followed by 3 days of oral busulfan (4 mg/kg/day) as conditioning. No case of transplant-related mortality occurred. The median number of days to neutrophil ( > 0.5 x 10(9)/l) and platelet ( > 20 x 10(9)/l) recovery was 11 and 12, respectively. Cardiac toxicity was absent, while 12 patients (86%) had grade 3-4 mucositis. After a median follow-up of 9 months from ASCT, nine of 14 patients are alive in continuous complete remission (CR), four have relapsed at 3, 6, 8 and 9 months, and one died in CR1 from gastric cancer. Our data demonstrate the feasibility of a conditioning regimen based on high-dose idarubicin plus busulfan in elderly AML patients. Results concerning reduction of relapse rate need confirmation in a larger series with longer follow-up.
