Treosulfan has been incorporated in conditioning regimens for sustained remissions without substantial toxicity and treatment related mortality (TRM). We aimed to analyze the safety and efficacy of FluTreo conditioning regimen (fludarabine 150mg/m(2), treosulfan 42g/m(2)) in medically infirm patients. Patients' outcome was compared with a similar historical group treated with FluBuATG (fludarabine 150-180mg/m(2), busulfex 6.4mg/Kg, thymoglobulin-ATG 5-7.5mg/kg). Thirty one consecutive patients suffering from AML (21), MDS (6) or treatment-related AML (4) received FluTreo conditioning...

Acute graft-versus-host disease (aGVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and a major cause of nonrelapse mortality after allo-HSCT. A conditioning regimen plays a pivotal role in the development of aGVHD. To provide a platform for studying aGVHD and evaluating the impact of different conditioning regimens, we established a murine aGVHD model that simulates the clinical situation and can be conditioned with Busulfan-Cyclophosphamide (Bu-Cy) and Fludarabine-Busulfan (Flu-Bu)...

Post-transplant relapse is the leading cause of treatment failure in acute myeloid leukemia (AML) patients after reduced-intensity conditioning allogeneic hematopoietic stem cell transplantation (allo-HSCT). To improve their outcome, we evaluated the outcome of a sequential intermediate-intensity conditioning regimen combining fludarabine, cytosine arabinoside, amsacrine, cyclophosphamide, and either total body irradiation or busulfan (FLAMSA) in patients with intermediate or high-risk AML in first or second complete remission (CR)...

We have retrospectively compared survivals between acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) patients who received either a clofarabine/busulfan (CloB2A2) or a fludarabine/busulfan (FB2A2) RIC regimen for allogeneic stem cell transplantation. Between 2009 and 2014, 355 allotransplanted cases were identified from the SFGM-TC registry as having received either the FB2A2 (n = 316, 56% males, median age: 59.2 years, AML 78.5%, first complete remission [CR1] 72%, median follow-up: 20 months) or the CloB2A2 (n = 39, 62% males, median age: 60...

Nonmalignant hematologic disorders (NMHD) of childhood comprise a variety of disorders, including acquired severe aplastic anemia and inherited marrow failure syndromes. Patients with high-risk NMHD without matched related donors fare poorly with allogeneic hematopoietic alternative donor stem cell transplantation (allo-HSCT) and are at high risk for developing graft-versus-host disease following unmodified grafts. The authors retrospectively analyzed data on 18 patients affected by NMHD, lacking a human leukocyte antigen (HLA)-identical sibling donor, who underwent an alternative donor allo-HSCT at their institution between April 2005 and May 2013...

Haplo-HSCT has been used when HLA-matched siblings are not available. Conditioning regimens aim to reduce tumor burden prior to HSCT and provide sufficient immunoablation. We report the outcome of haplo-HSCT in 63 consecutive patients from 2/2013 to 12/2015 (19 females/44 males) with high-risk or relapsed/refractory hematological malignancies (n=29-AML; 8-sAML; 19-ALL; 5-advanced-MDS; 2-CML-BC). Median age was 20 years (range: 1.1-49). Twenty-one patients achieved remission prior to transplant, while 42 did not...

Reduced intensity conditioning for allogeneic hematopoietic stem cell transplantation (allo-HSCT) is often proposed for patients with comorbidities. To enhance engraftment and limit graft-versus-host disease (GVHD), antithymoglobulin (ATG) is usually used. However, the dose needed remains unclear unlike myeloablative conditioning. In order to clarify this point, we conducted a retrospective study on patients who received a reduced intensity conditioning allo-HSCT based on a 2-day fludarabine and busulfan treatment with either 1 or 2 days of ATG treatment...

Reduced-intensity conditioning (RIC) has been shown to have similar overall survival (OS) but higher relapse rates compared with myeloablative (MAC) regimens in patients with myeloid malignancies undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Using propensity score matching (PSM) analysis, well-balanced pairs of different variables can be compared effectively. We retrospectively compared allo-HSCT recipients with acute myeloid leukemia or myelodysplasia receiving a RIC regimen (FBT200; fludarabine 30 mg/m(2)/day for 4 days, busulfan 3...

Myeloablative conditioning (MAC) regimens are commonly used in transplantation for chronic granulomatous disease (CGD) but are associated with toxicity. Reduced-intensity conditioning (RIC) regimens have lower toxicity but may fail to achieve stable donor chimerism. We report a comparison between 4 patients who received a RIC regimen consisting of alemtuzumab (1 mg/kg), fludarabine (150 mg/m(2)), and melphalan (140 mg/m(2)) and 14 patients who received a MAC regimen consisting of busulfan (area under the curve, 1800 to 2000 µMol/min twice daily × 4 days), cyclophosphamide (50 mg/kg/day × 4), and antithymocyte globulin (15 mg/kg twice daily on days -2 and -1, then daily on days +1 and +2)...

PURPOSE OF REVIEW: Bone marrow transplantation is the only curative treatment for severe thalassemia. Since its successful first report in 1981, more than 4000 patients with this disease worldwide underwent bone marrow transplantation. The purpose of this review is to update the most recent reports of matched sibling donor hematopoietic stem cell transplantation in thalassemia. RECENT FINDINGS: Advanced and improved transplant techniques result in the improved outcomes in those transplants from a matched sibling donor with transplant-related mortality less than 5%...

There is at present little data to guide the choice of conditioning for patients with lymphoma undergoing reduced-intensity conditioning (RIC) allogeneic stem cell transplantation (SCT). In this study, we compared the outcomes of patients undergoing RIC SCT who received fludarabine and melphalan (FluMel), the standard RIC regimen used by the Spanish Group of Transplantation, and fludarabine and busulfan (FluBu), the standard RIC regimen used by the Dana-Farber Cancer Institute/Brigham and Women's Hospital. We analyzed 136 patients undergoing RIC SCT for lymphoma with either FluBu (n = 61) or FluMel (n = 75) conditioning between 2007 and 2014...

This article presents the haematopoietic stem cell transplantation (SCT) results of the complete Dutch Fanconi anaemia (FA) patient cohort. Sixty-eight Dutch FA patients have been transplanted since 1972. In total, 63 (93%) patients engrafted, 54 after first SCT and 9 after second SCT. Fludarabine (FLU)-based conditioning was associated with decreased graft failure (odds ratio 0·21, P = 0·01), decreased early mortality (hazard ratio 0·25, P = 0·01) and improved 5-year overall survival (FLU 87·8% [standard error (SE) 5·1%] versus non-FLU 59·3% [SE 9·5%], P = 0·01)...

Busulfan, fludarabine, and melphalan as hematopoietic cell transplant conditioning, was used in 6 patients aged 1 to 19 years with very high-risk myeloid malignancies. This dose regimen had an acceptable toxicity profile resulting in complete donor engraftment even following transplantation of small 2/6 antigen disparate umbilical cord blood grafts. It provided excellent disease control as all patients had high-risk features in terms of cytogenetics, therapy-related leukemia, and/or significant measurable disease before transplant...

Pretransplant conditioning regimens critically determine outcomes in the setting of allogeneic stem cell transplantation (allo-SCT). The use of nucleoside analogs such as fludarabine (Flu) in combination with i.v. busulfan (Bu) has been shown to be highly effective as a pretransplant conditioning regimen in acute myeloid leukemia (AML), chronic myeloid leukemia (CML), and myelodysplastic syndrome (MDS). Because leukemia relapse remains the leading cause of death after allo-SCT, we studied whether clofarabine (Clo), a nucleoside analog with potent antileukemia activity, can be used to complement Flu...

Reduced-intensity conditioning (RIC) has been used increasingly for allogeneic hematopoietic cell transplantation to minimize transplant-related mortality while maintaining the graft-versus-tumor effect. In B cell lymphoid malignancies, reduced-intensity regimens containing rituximab, an antiCD20 antibody, have been associated with favorable survival; however, the long-term outcomes of rituximab-containing versus nonrituximab-containing regimens for allogeneic hematopoietic cell transplantation in B cell lymphoid malignancies remain to be determined...

Novel approaches to pre-transplant conditioning are needed to improve treatment of advanced T-cell malignancies. We investigated the synergism of fludarabine (Flu), clofarabine (Clo), busulfan (Bu), and romidepsin (Rom) in T-cell lines and patient-derived cell samples. [Flu+Clo+Bu+Rom] had combination indexes of 0.4-0.5 at ∼50% cytotoxicity in PEER and SUPT1 cells, suggesting synergism.

Fludarabine with busulfan (FB) and fludarabine with melphalan (FM) are commonly used reduced-intensity conditioning (RIC) regimens. Pharmacokinetic dosing of busulfan (Bu) is frequently done for myeloablative conditioning, but evidence for its use is limited in RIC transplants. We compared transplant outcomes of FB versus FM using i.v. Bu targeted to the area under the curve (AUC). A total of 134 RIC transplants (47 FB and 87 FM) for acute myelogenous leukemia and myelodysplastic syndrome were identified, and median follow-up of the cohort was 40 months (range, 0 to 63...
