Reduced Intensity

Allogeneic hematopoietic cell transplantation (allo-HCT) preconditioning intensity, donor choice, and graft-versus-host disease (GVHD) prophylaxis for advanced myelofibrosis (MF) have not been fully elucidated. Thirty-five patients with advanced MF were treated with reduced-intensity conditioning (RIC) allo-HCT. We searched for matched sibling (n=16) followed by matched (n=10) or mismatched (n=5) unrelated and familial mismatched donors (n=4). Preconditioning regimen consisted of fludarabine (total 150 mg/m2) and busulfan (total 6.4 mg/kg) with total body irradiation≤ 400cGy. All showed engraftments, but four (11.4%) showed either leukemic relapse (n=3) or delayed graft failure (n=1). Two-year overall survival (OS) and non-relapse mortality (NRM) was 60.0% and 29.9%, respectively. Acute GVHD was observed in 19 patients, and grade III-IV acute GVHD was higher with HLA-mismatch (70% vs. 20%, p=0.008). Significant hepatic GVHD was observed in nine patients (5 acute, 4 chronic), and six of them died. Multivariate analysis revealed inferior OS with HLA-mismatch (HR=6.40, 95%CI 1.6-25.7, p=0.009) and in patients with high ferritin level at post-HCT D+21 (HR=7.22, 95%CI 1.9-27.5, p=0.004), which were related to hepatic GVHD and high NRM. RIC allo-HCT can be a valid choice for advanced MF. However, HLA-mismatch and high post-HCT ferritin levels related to significant hepatic GVHD should be regarded as poor-risk parameters.

Host Macrophage

Acute graft-versus-host disease (GVHD) results from the attack of host tissues by donor allogeneic T cells and is the most serious limitation of allogeneic hematopoietic cell transplantation (allo-HCT). Host antigen-presenting cells are thought to control the priming of alloreactive T cells and the induction of acute GVHD after allo-HCT. However, whereas the role of host DC in GVHD has been established, the contribution of host macrophages to GVHD has not been clearly addressed. We show that, in contrast to DC, reducing of the host macrophage pool in recipient mice increased donor T cell expansion and aggravated GVHD mortality after allo-HCT. We also show that host macrophages that persist after allo-HCT engulf donor allogeneic T cells and inhibit their proliferation. Conversely, administration of the cytokine CSF-1 before transplant expanded the host macrophage pool, reduced donor T cell expansion, and improved GVHD morbidity and mortality after allo-HCT. This study establishes the unexpected key role of host macrophages in inhibiting GVHD and identifies CSF-1 as a potential prophylactic therapy to limit acute GVHD after allo-HCT in the clinic.

Abstract Aim To identify the causes and consequences of omission and/or reduction of methotrexate (MTX) doses in graft-versus-host disease (GVHD) prophylaxis used during allogeneic hematopoietic cell transplantation (alloHCT). Method We conducted a retrospective medical record review of 125 alloHCTs performed between the years 2011 and 2013 at our hospital where MTX (15, 10, 10, 10 mg/m2 intravenously on day [D] +1, D+3, D+6, D+11 respectively) is used with cyclosporine as GVHD prophylaxis. The association of MTX dose omission with overall survival (OS), non-relapse mortality (NRM) and acute GVHD, measured from a landmark of D+12, was evaluated with univariate and multivariate analysis. Results 116 patients (median age 48, range 17-67, 59% male) were eligible for analysis. Commonest indications for alloHCT were acute leukemia (47%) and chronic lymphoproliferative disorders (28%). Conditioning was myeloablative in 54%, donors were siblings in 53%, and grafts were peripheral blood in 87%. 85 patients (73%) received all four full doses of MTX. 22 patients had a dose omission at D+11, and two at both D+6 and D+11. 43 patients were given folinic acid rescue. Documented reasons for MTX alteration were mucositis (n = 22; World Health Organisation mucositis grade 4 in 16 patients, grade 3 in 4 patients and grade 2 in 2 patients), fluid overload (n = 10), liver impairment (n = 8, median bilirubin 83 micromol/L, range 19-204 micromol/L, normal < 21 micromol/L), renal impairment (n = 8, median creatinine 138 micromol/L, range 67-276 micromol/L, normal 45-90 micromol/L) and sepsis (1). MTX omission was associated with poorer OS (48% vs 90%; hazard ratio [HR] for mortality 5.4, 95% CI 2.5-11.7, P < 0.001, Figure 1) and higher NRM (39% vs 5%, HR 10.2, 95% CI 3.4-30.8, P < 0.001, Figure 2) at 12 months post landmark. A pattern of ongoing NRM was observed beyond day 100. Strikingly, those patients who received all four full doses of MTX had NRM of 0% at 100 days post landmark. There was no difference in rates of grade 2-4 (24% vs 22%, P = .950) or grade 3-4 (9% vs 11%, P = .662) acute GVHD, or relapse (20% vs 17%, P = .514), at day 100 post landmark. Conclusion MTX dose reduction has no significant impact on GVHD development, suggesting that MTX omissions or other adjustments of GVHD prophylaxis did not lead to enhanced T cell activation. However, it seems that the need to reduce MTX indicates an increased risk of NRM, likely reflecting ongoing organ dysfunction. Older patients or those with pre-transplant co-morbidities may be better served by strategies that lower the likelihood of organ toxicity, including reduced intensity conditioning and lower initial doses of MTX.

Background: Preconditioning intensity, donor choice and graft- versus-host disease (GVHD) prophylaxis of allogeneic hematopoietic cell transplantation (allo-HCT) for advanced myelofibrosis (MF) have not been fully elucidated. Methods: Thirty-five patients with advanced MF were treated with reduced-intensity conditioning (RIC) allo-HCT. We searched for matched sibling donors first, followed by matched or mismatched unrelated donors and familial mismatched donors. Preconditioning regimen consisted of fludarabine (total 150 mg/m2) and busulfan (total 6.4 mg/kg) with total body irradiation ⩽400cGy. Results: All showed engraftments, but four showed either leukemic relapse or delayed graft failure. Two-year overall survival (OS) and non-relapse mortality (NRM) was 60.0% and 29.9%, respectively. Acute GVHD was observed in 19 patients, and grade III–IV acute GVHD (eight grade III and four grade IV) was higher in human leukocyte antigen (HLA)-mismatched donor HCT compared with HLA-matched HCT (70% versus 20%). Chronic GVHD was observed in 16 patients, and a cumulative incidence of severe chronic GVHD was 33% in HLA-mismatched donor HCT and 7.7% in HLA-matched HCT. Significant hepatic GVHD was observed in nine patients (five acute, four chronic) and six of them died. Multivariate analysis revealed inferior OS in HLA-mismatched donor HCT (hazard ratio (HR) = 6.40, 95% confidence interval (CI) 1.6–25.7, p = 0.009) and in patients with high ferritin level at the time of pre-conditioning period (HR = 7.22, 95% CI 1.9–27.5, p = 0.004), which were related to higher incidence of hepatic GVHD with high NRM rate. Conclusion: RIC allo-HCT can be a valid choice providing graft- versus-fibrosis effect for advanced MF patients. However, HLA-mismatched donor and high pre-HCT ferritin level related to fatal hepatic GVHD should be regarded as poor-risk parameters.

Abstract Background: Allogeneic hematopoietic cell transplantation (allo-HCT) remains the only curative therapeutic modality for patients with myelofibrosis (MF). However, the optimal conditioning regimen for allo-HCT either in the myeloablative conditioning (MAC) or in the reduced intensity conditioning (RIC) setting is not well known. Methods: Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we identified adults aged ≥18 years with MF who underwent allo-HCT between the years 2008-2018. Donor types included matched sibling donor (MSD), 8/8 matched unrelated donor (MUD), and 7/8 MUD. Outcomes were compared separately in the MAC and RIC cohorts based on the most common conditioning regimens used in each setting - MAC [(Fludarabine/Busulfan (Flu/Bu) vs. Busulfan/cyclophosphamide (Bu/Cy)] or RIC [(Flu/Bu vs. Fludarabine/melphalan (Flu/Mel)]. Overall survival (OS), disease free survival (DFS), non-relapse mortality (NRM), relapse, acute and chronic graft versus host disease (GVHD) and GVHD-free relapse-free survival (GRFS) were evaluated. Survival analysis was done using Kaplan-Meier method and significant predictors were evaluated using Cox-proportional hazard regression method. Multivariable regression model included main effect (conditioning regimen) and covariates (patient age, gender, race, CMV match, disease subtype, DIPSS at HCT, comorbidities score (HCT-CI), Karnofsky performance status, prior therapy (ruxolitinib use/splenic radiation therapy/splenectomy), interval between diagnosis and transplant, conditioning intensity, stem cell source, donor-recipient HLA-match, GVHD prophylaxis, ATG/alemtuzumab use, transplant year, and center affect). All analyses were performed at a two-sided significance level of 0.05. Results: Of 872 patients who met the study criteria, 379 patients underwent allo-HCT using MAC (Flu/Bu=247, Bu/Cy=132) and 493 patients using RIC (Flu/Bu=166, Flu/Mel=327). Key baseline characteristics of the patients are summarized in Table 1. In multivariable analysis, significant differences in outcomes were observed in the MAC and RIC setting based on the choice of conditioning regimen (Table 2). In the MAC setting, Bu/Cy was associated with a higher risk of acute GVHD (grade 2-4 HR 2.33, 95% CI 1.67-3.25, p&lt;0.01; grade 3-4 HR 2.31, 95% CI 1.52-3.52, p&lt;0.01) and inferior GRFS (HR 1.94, 95% CI 1.49-2.53, p&lt;0.01) as compared to Flu/Bu. In the RIC setting, Flu/Mel was associated with inferior OS (HR 1.80, 95% CI 1.15-2.81, p&lt;0.01), higher risk of NRM (HR 1.81, 95% CI 1.12-2.91, p=0.01) and acute GVHD (grade 2-4- HR 1.45, 95% CI 1.03-2.03, p=0.03; grade 3-4 HR 2.21, 95%CI 1.28-3.83, p&lt;0.01) as compared to Flu/Bu. These higher risks associated with Flu/Mel were primarily observed early post-transplant. The results were consistent when the outcomes were evaluated based on the two common melphalan doses employed in the RIC setting (100mg/m 2 vs 140mg/m 2). Conclusions: Our study demonstrates that the choice of conditioning regimen significantly influences the outcomes of allo-HCT in MF. The results favor Flu/Bu based conditioning in the MAC (lesser acute GVHD and better GRFS) and RIC (better OS, lower NRM, lower acute GVHD) setting. Hence, this aspect should be explored in future studies as the modification of conditioning strategies could lead to improved outcomes. Figure 1 Figure 1.

Abstract Abstract 2319 Background: Graft-versus-host disease (GVHD) is a common immunologic complication after allogeneic hematopoietic cell transplantation (HCT). Cyclosporine or tacrolimus in combination with other agents represent widely accepted standards of care as immunosuppressive regimens after HCT. Results of open-label randomized prospective phase III studies have indicated that the risk of grades II-IV acute GVHD after bone marrow transplantation with related or unrelated donors is lower with the use of tacrolimus as compared to cyclosporine, in combination with methotrexate. The current study was carried out to compare results with tacrolimus versus cyclosporine after HCT with G-CSF-mobilized blood cells. Patients and methods: The study cohort included 510 consecutive patients who received a first G-CSF-mobilized blood cell graft from related or unrelated donors after high-intensity conditioning for treatment of hematological malignancies between 7/1/2003 and 2009 at our center. All patients received ursodeoxycholic acid from 2 weeks before conditioning until 90 days after HCT to prevent hepatic complications, and all patients received immunosuppression with either tacrolimus or cyclosporine in combination with methotrexate after HCT. Endpoints included grades II-IV acute GVHD, grades III-IV acute GVHD, chronic GVHD, end of treatment for chronic GVHD, overall survival, disease-free survival, recurrent malignancy and nonrelapse mortality. Multivariate Cox regression models were used to evaluate hazard ratios for these endpoints with tacrolimus as compared to cyclosporine. The models were adjusted for patient age, donor type, recipient and donor gender combination, disease type, disease risk category, use of total body irradiation in the conditioning regimen, and year of HCT. The analysis was carried out as of July, 2010. Results: The median age of patients was 47 (range, 1 to 66) years. Diagnosis at HCT was acute myeloid leukemia in 200 (39%) patients, acute lymphoblastic leukemia in 73 (14%), chronic myeloid leukemia in 49 (10%), myelodysplastic syndrome or myeloproliferative disorders in 160 (31%) and other lymphoid malignancies in 28 (5%). Total body irradiation was used for conditioning in 168 (33%) patients. Of the 510 patients, 277 (54%) had HLA-matched related donors, 203 (40%) had HLA-matched unrelated donors, and 30 (6%) had HLA-mismatched related or unrelated donors. Outcomes according to immunosuppression with tacrolimus or cyclosporine are shown in Table 1. Multivariate analysis showed no statistically significant differences between tacrolimus and cyclosporine for any of the endpoints tested (Table 2), although the results showed a trend suggesting that the risk of non-relapse mortality might be lower with tacrolimus as compared to cyclosporine. Conclusion: In this retrospective analysis, tacrolimus offered no statistically significant advantage over cyclosporine for preventing grades II-IV acute GVHD after HCT with G-CSF-mobilized blood cells, and results for other outcomes also showed no statistically significant differences. Although our data support the hypothesis that either regimen could be an acceptable standard of care for immunosuppression, the number of patients analyzed in this study is not sufficient to completely exclude clinically meaningful differences in outcomes with the two regimens. Disclosures: Off Label Use: Tacrolimus and cyclosporine for immunosuppression after allogeneic hematopoietic cell transplantation.
