TREOSULFAN-FLUDARABINE CONDITIONING REGIMEN WITH POST-TRANSPLANT HIGH-DOSE CYCLOPHOSPHAMIDE: A RETROSPECTIVE ANALYSIS (ePoster area) - Feb 14, 2024 - Abstract #EBMT2024EBMT_2777; In combination with PTCy, short courses of tacrolimus or everolimus and mycophenolate mofetil (MMF) were used as GVHD prophylaxis. Treosulfan-fludarabine conditioning regimen combined with PTCy had low transplantation-related mortality and acceptable relapse rate, especially taking into account the relatively high age of the patients, high or very high DRI in more than half of the patients, and the high proportion of patients with active disease and/or positive MRD at transplant.

TREOSULFAN PLUS FLUDARABINE (CLYDE) - Feb 14, 2024 - Abstract #EBMT2024EBMT_2769; This reduced intensity conditioning (T10F) would seem to limit relapse and GvHD without increasing TRM. Multicentric and larger studies with similar platforms are needed to confirm our results.

THE RESULTS OF ALLOGENEIC HSCT AFTER TREOSULFAN (CLYDE) - Feb 14, 2024 - Abstract #EBMT2024EBMT_2707; In the conditioning regimen treosulfan was combined with different cytostatics, mostly fludarabine (n=72; 84,7%) and cyclophosphamide (n=11; 12,9%)...There was no significant difference in outcome after treosulfan-fludarabine-thiotepa regimen versus other treosulfan-based regimens... Treosulfan-based regimen seems to be safe and effective in pediatric AML patients and may be used as an alternative to busulfan-based protocols, especially in patients with pre-HSCT high risk factors of severe regimen-related toxicities.

SEQUENTIAL CONDITIONING DOES NOT IMPROVE OUTCOMES OF ALLOGENEIC STEMCELL TRANSPLANTATION IN CMML PATIENTS (GALA) - Feb 14, 2024 - Abstract #EBMT2024EBMT_2520; This retrospective study from the Department of Stem Cell Transplantation at the University Medical Center Hamburg, Germany, compared allo-SCT outcomes in CMML patients across three conditioning regimes: Thiotepa-Busulfan (TB), Sequential FLAMSA-Busulfan Fludarabine (FLAMSA-FB), and Treosulfan-Fludarabine (Treo-Flu)...FLAMSA-FB regimen consists of fludarabine (30 mg/m2 ; total dose 120 mg/m2 ), amsacrine (100 mg/m2 ; total dose 400 mg/m 2 ), and cytarabine (1 g/m2 ; total dose 4 g/m 2 ) therapy from days -11 to minus -8, followed by a three-day interval without therapy and Busulfan from day -4 to -2 with a total dose of 6.4mg/Kg and Fludarabine on day -4 and -3 (30 mg/m2, total dose 60mg/m 2 ).Treo-Flu regimen consisted of Treosulfan (12 g/m2 , total dose 36 mg/m2 ) on days-6 to -4 and fludarabine (30 mg/m2 ; total dose 150 mg/m2 ) on days -6 to -2... Our study suggests that sequential conditioning with FLAMSA-FB does not improve Transplant outcomes in patients undergoing allo-SCT for CMML.

IMPROVING OUTCOMES IN MDS/MPN: TREOSULFAN-BASED CONDITIONING FOR ALLOGENEIC HEMATOPOIETIC STEM CELL TRANSPLANTATION (ePoster area) - Feb 14, 2024 - Abstract #EBMT2024EBMT_1824; Treosulfan-based conditioning seems to be effective and well-tolerated in patients with MDS/MPN undergoing allo-HSCT, for both low risk of relapse and low TRM. Further studies on larger cohorts are necessary to confirm these findings and to clarify the role of pre-transplant induction treatment with HMAs or intensive chemotherapy in this disease setting.

IMPACT OF PRETRANSPLANT MRD IN PATIENTS ALLOGRAFTED FOR AML AFTER TREOSULFAN-BASED CONDITIONING (CLYDE) - Feb 14, 2024 - Abstract #EBMT2024EBMT_1787; Our analysis shows that Flu/Treo-based conditioning cannot eliminate the negative impact of pretransplant MRD positivity on RFS. However, MRD positivity did not have an impact on OS in our analysis, which may be explained in part by graft-derived alloreactivity implied by cGvHD.
