Abstract Introduction: The introduction of reduced intensity conditioning (RIC) regimens, associated with less NRM, has significantly broadened transplant eligibility to older patients. However, graft-versus-host disease (GVHD) continues to be a major problem, even with RIC allo-HCTs. At our institution, we have been routinely adding mycophenolate mofetil (MMF) to the standard methotrexate (MTX) plus Tacrolimus combination in the majority of RIC allo-HCT recipients from unrelated donors. However, there is a paucity of data on whether this approach further decreases GVHD rates without increasing NRM and risk of relapse. To answer these questions, we retrospectively analyzed data from 177 patients who received MMF, MTX and Tacrolimus (MMF + Tac/MTX) as part of their GVHD prophylaxis and compared their outcomes to those of 117 patients who received MTX and Tacrolimus alone (Tac/MTX). Patients and methods: The study included a total of 294 consecutive patients who underwent RIC allo-HCT at Washington University Medical Center between January 2006 and December 2013. The data was analyzed for patients who received GVHD prophylaxis with either tacrolimus/methotrexate (Tac/MTX) or tacrolimus/mycophenolate mofetil/methotrexate (MMF+Tac/MTX). Cumulative incidence of relapse was estimated treating death in remission as competing risk event. Cumulative incidence of NRM was calculated considering death in relapse as competing risk event. Univariate analysis was performed to evaluate variables, and multivariate Cox models with a backward selection procedure were done to assess whether GVHD prophylaxis was an independent predictor after adjusting other factors significant in the univariate analysis. All analyses were two-sided, and significance was set at a p-value of 0.05. Statistical analyses were performed using library cmprsk in statistical package R for competing risk analysis and SAS 9.4 (SAS Institutes, Cary, NC) for all other analyses. Results: 177 patients (60.2%) received MMF+Tac/MTX whereas 117 patients (39.8%) received Tac/MTX. Median age was 61 years in the MMF+Tac/MTX group and 58 years in the Tac/MTX group, and the most common diagnosis was AML(31%) followed by NHL (26%) and MDS (19%) in the MMF+Tac/MTX group vs. AML (45%) followed by MDS (14%) and NHL (13%) in the Tac/MTX group. There were more transplants from unrelated and mismatched donors, higher intermediate ASMBT RFI risk group patients and more frequent use of conditioning with Flu/Bu/Thymo regimen in the MMF+Tac/MTX cohort. In particular 160 (90.4%) patients in MMF+Tac/MTX group received thymoglobulin as part of their conditioning, compared to 64 (54.7%) patients in the Tac/MTX group (p < 0.001). The cumulative incidence of grade 2-4 aGVHD at day 100 was 31.0% in the MMF+Tac/MTX group vs. 36.2% in the Tac/MTX group (p=0.191) while as grade 3-4 aGVHD at day 100 and 1 year were 16.8% and 25.9% in the Tac/MTX group compared to 8.0% and 12.4% in the MMF+Tac/MTX group, respectively (p=0.010). However, after adjusting for the thymoglobin use there was no significant difference in the incidence of grade 3-4 aGVHD in these two groups (p=0.129). To eliminate the confounding effect of thymoglobulin, we performed a subgroup analysis of patients without thymoglobulin. Given the small number of samples (n=17 in MMF+Tac/MTX and n=53 in Tac/MTX), propensity score matching was used and the results again showed no significant difference in severe aGVHD between two groups (p=0.219). The incidence of cGVHD at 1 year was 15.3% and 21.6% in MMF+Tac/MTX and Tac/MTX, respectively (p=0.645). Although patients in the MMF+Tac/MTX group had more unfavorable disease risk, the cumulative incidence of relapse at 3 years was not significantly different: 40.8% in the MMF+Tac/MTX group and 39.8% in the Tac/MTX group (p=0.941). 5-year OS was 33.7% in the MMF+Tac/MTX group, compared to 35.1% in the Tac/MTX group (p=0.769). Conclusion: Here we report transplant outcomes of RIC allo-HCT patients who received MMF in addition to Tac/MTX for GVHD prophylaxis. Interestingly we did not see any increase in NRM or relapse rates with additional immune-suppression from adding MMF in these patients. However, addition of MMF to the Tac/MTX regimen did not result in any significant improvement in acute or chronic GVHD outcomes in our patients. Based on these results we do not recommend adding MMF to Tac/MTX regimen for GVHD prophylaxis in RIC allo-HCT patients. Disclosures Uy: Novartis: Research Funding.

Myelomonocytic Leukemia

INTRODUCTION: MDS/MPN are a group of clonal hematopoietic disorders with overlapping features of MDS and MPN, and include chronic myelomonocytic leukemia (CMML), atypical chronic myeloid leukemia (aCML), MDS/MPN-unclassifiable along with juvenile myelomonocytic leukemia and MDS/MPN with ring sideroblast and thrombocytosis. Therapeutic options for MDS/MPN remain limited and BMT remains the only modality with curative potential. However, the overall survival of these patients following BMT remains poor marked by a high incidence of non-relapse mortality (NRM) and relapse. Moreover, most of the published cohorts consisted of patients receiving matched related donor grafts, with limited data on the outcomes of patients receiving grafts from alternative donors. In the current study, we aim to describe outcomes of BMT for MDS/MPN using PTCy as the GVHD prophylaxis platform and primarily haploidentical related (haplo) donors. PATIENTS AND METHODS: We performed a retrospective analysis of patients with MDS/MPN who underwent BMT with PTCy at Johns Hopkins between 1/2011-1/2019. Kaplan-Meier analysis was used to evaluate overall survival (OS), relapse-free survival (RFS), and GVHD/relapse-free survival (GRFS). Cumulative incidence of relapse and non-relapse mortality (NRM) were estimated non-parametrically in presence of competing events where NRM was a competing event of relapse, and vice versa. Univariate analysis was used to evaluate the impact of donor type, HCT-CI, and karyotype on these clinical outcomes via Cox proportional hazard models for OS/RFS/GRFS, and Fine-Gray's sub-distribution (s) hazard models for relapse/NRM/GVHD. RESULTS: Thirty-four consecutive patients (11 women and 23 men) with a median age of 63 years (range 51-74) at the time of BMT were identified. Of these, 21 (61.8%) had haplo donors and 31 (91%) received non-myeloablative conditioning with fludarabine, cyclophosphamide and total body irradiation. Median follow up was 3.9 years (range: 24 days - 8.4 years) based on reverse Kaplan-Meier approach. Other patient, disease and BMT related details are shown in Table 1. Time to neutrophil and platelet recovery was 22 days (range 19 - 28 days) and 31 days (range 22 - 67 days), respectively. Two (6%) patients had primary graft failure, both had received a marrow graft. At 3-years, probability of OS was 46% (95% CI: 31% - 68%), 3 RFS was 30% (17% - 51%), GRFS was 26% (14%-48%), cumulative incidence of relapse was 59% (95% CI: 41% - 77%) and incidence of NRM was 12% (95% CI: 1% - 23%). The incidence of grade 2-4 acute GVHD at 1 year following HCT was 24% but no patients had grade 3-4 acute GVHD. The cumulative incidence of any chronic GVHD at 3 years was 20% with 3 (9%) patients requiring systemic therapy. Univariate analysis showed that HCT-CI score at the time of HSCT was associated with higher incidence of relapse (sHR 5.22, 95% CI 2.26-12.08) and inferior RFS (HR 3.09, 95% CI 1.16-8.2). Other patient-, disease- and HCT-related factors were not statistically significantly associated with these clinical outcomes. The outcomes of patients with haplo donors (n=21) were also estimated at 3 years and estimates of OS were 56% (95% CI 38% - 82%), RFS 42% (95% CI 26% - 70%), GRFS 37% (21% - 66%), cumulative incidence of relapse 43% (95% CI 21% - 66%), NRM 14% (95% CI 1% - 30%), chronic GVHD 21% (95% CI 2% - 40%). No patients developed grade 3-4 acute GVHD. While the sample size is limited, comparison of K-M estimates for RFS and relapse with haplo donor (n=21) and matched related/unrelated donor (n=12), is shown in Figure 1. CONCLUSIONS: We report, for the first time, clinical outcomes of BMT for MDS/MPN with the PTCy based GVHD platform, and outcomes appear comparable with those previously described in other retrospective studies using conventional approach. Although limited by sample size for a statistical analysis, the outcomes with haplo donor BMT appear promising. The relatively high incidence of relapse in these patients appears to be the major factor contributing adversely to outcomes, while NRM and GVHD incidence with our non-myeloablative conditioning PTCy platform are low. We are currently exploring strategies to decrease relapse rates to further improve BMT outcomes in these patients.

Abstract Allogeneic hematopoietic stem cell transplantation (allo-SCT) following a non-myeloablative (NMA) or reduced-intensity conditioning (RIC) is considered a valid approach to treat patients with refractory/relapsed Hodgkin's lymphoma (HL), in particular those having failed a previous autologous SCT (ASCT). When an HLA-matched donor is lacking, a graft from a haploidentical donor (HAPLO), a mismatched unrelated donor (MMUD) or cord blood (CB) might be considered. In this retrospective, registry-based study, we compared the outcome of patients with HL undergoing a RIC or NMA allo-SCT from a HAPLO, MMUD or CB graft. After detailed review of our database, we found 98 consecutive patients with HL who underwent a NMA/RIC allo-SCT from an alternative HLA-mismatched donor at 24 French and Belgian centers between January 2009 and December 2014. Probabilities of overall survival (OS), event-free survival (EFS) and graft-versus-host disease (GVHD)-free Relapse-free Survival (GRFS) were determined using the Kaplan-Meier method. The cumulative incidences of relapse (CIR), non-relapse mortality (NRM) and cGVHD were studied using a competing risk methodology. We defined GRFS as the probability of being alive without evidence of relapse, grade 3-4 acute GVHD or chronic GVHD (all grades included). Regarding conditioning regimens and intensity, patients in the HAPLO group (n = 34) received a T-cell replete allo-SCT after a NMA (as described by the Baltimore group in Luznik et al, Biology of Blood and Bone Marrow Transplantation, 2008, n = 31, 91%) or a RIC (n = 3, 9%) followed by post-transplant cyclophosphamide (PT CY). Patients in the MMUD group (n = 27) received a variety of NMA (n = 7, 26%) and RIC (n = 20, 74%). All patients in the CB group received a RIC (n = 37, 37%). All but one patient (n = 33) in the HAPLO group received the following GVHD prophylaxis: Cy 50 mg/kg on day +3 and day +4, tacrolimus or CsA and mycophenolate mofetil started on day +5. One patient received only one day of PT CY 50mg/kg at day +3 and also received ATG on day -2 and day -1 for a total dose of 5mg/kg. GVHD prophylaxis for MMUD consisted of CsA or tacrolimus, started on day -3 or day -1 in all patients according to local practice with either mycophenolate mofetil (n = 25, 89%) or methotrexate 15 mg/m2 at day +1, 10 mg/m2 at day+3 and day +6 (n = 3, 11%). GVHD prophylaxis consisted of CsA and mycophenolate mofetil starting on day -3 for all CB patients. Median age at allo-SCT was 28 (range: 16-68). The median number of treatments before allo-SCT was 4 (range: 3-6). An ASCT had been performed prior to allo-SCT in 77% (n = 26), 100% (n = 28%) and 100% (n = 37) of cases in the HAPLO, MMUD and CB group, respectively. Disease status at allo-SCT per Cheson 1999 criteria was complete remission in 51% (n = 51), partial response in 32% (n = 31), stable or progressive disease in 11% (n = 11), while no data was available in 5% (n = 5). Positron emission tomography was positive at allo-SCT in 45% (n = 44), negative in 43% (n = 43) while no data was available in 12% (n = 12). Median follow-up was 31 months (range: 3 - 79). In univariate analysis we observed a significantly higher probability of GRFS in patients who received a HAPLO allo-SCT (52% versus 22% and 31% at three years in the HAPLO, CB and MMUD groups, respectively, p = 0.02, Logrank test). Higher GRFS was also observed in patients receiving a NMA conditioning compared to a RIC (50% versus 27% at three years, p = 0.009, Logrank test). We did not observe significant differences in OS, EFS or NRM, according to donor type. Disease status at allo-SCT significantly impacted OS (p<0.001, Logrank test), CIR (p = 0.02, Gray's test), EFS (p < 0.001, Logrank test) and GRFS (p = 0.002, Logrank test). After adjustment for significant covariates, MMUD and CB remained associated with significantly lower GRFS (HR = 2.02, p = 0.03 and HR = 2.43, p = 0.009, respectively, Cox model) compared to HAPLO donors. In conclusion, significantly higher GRFS was observed in HL patients receiving a haploidentical NMA/RIC T-cell replete allo-SCT with PT CY. How this separation of the GVH from the graft-versus-lymphoma effect occurs requires further investigations. Haploidentical NMA/RIC T-cell replete allo-SCT with PT CY for advanced HL should now be compared with NMA/RIC allo-SCT from related and unrelated HLA-compatible donors, ideally within prospective trials.

Abstract Introduction: Atrial fibrillation (AF) is not uncommon in cancer patients with grade 3-4 thrombocytopenia (platelets &lt;50x10 9/L). The risk of bleeding appears to outweigh the risk of thrombosis in acute leukemia patients. There are no published data regarding management of anticoagulation (AC) and rates of bleeding and thrombosis in other cancer types. Aim: To assess AC management and incidence of bleeding and thrombosis in thrombocytopenic cancer patients with AF. Methods: Single-center retrospective cohort study. The study included adults with active cancer, grade 3-4 thrombocytopenia (platelets &lt;50x10 9/L) and AF with CHA 2DS 2-VASc ≥1, irrespective of AC status prior index. Patients with acute leukemia were excluded. Patients were indexed when platelets &lt;50x10 9/L. AC management was classified as either "No-AC", if AC was withheld (i.e., stopped or not started) at index, or "Continue-AC", if AC was continued. Arterial thromboembolism (ATE; ischemic stroke, transient ischemic attack or systemic embolism) and ISTH-defined major bleeding were recorded over 30 days. The 30-day cumulative incidence of composite and individual outcomes with corresponding 95% confidence intervals (CI) was calculated for each management group (death as competing risk). A Cox proportional hazards model was used to calculate hazard ratios (HR) and corresponding 95% CI for outcomes between the No-AC and Continue-AC groups, with death as a competing risk (Fine and Gray model). Results: The eligibility criteria were met by 131 patients. At study index, AC was not given in 90 (69%) patients and continued in 41 (31%). Table 1 shows patient characteristics overall and stratified for management. The median age was 80 years )IQR 70-82) and 55 (42%) were females. Most patients were inpatients at index (70%) and had newly diagnosed cancer (70%). 64% had solid malignancy, and the remainder had hematological malignancy. The majority (92%) had AF prior to study index, while 8% had AF newly diagnosed at index. The median CHA 2DS 2-VASc score was 4 [IQR 3-5] and 18% had a prior stroke. Median platelet counts were 42 x 10 9/L at index and the median HASBLED score was 5 [3-5]. Only 44% of the No-AC group were receiving AC prior index, compared with 95% in the Continue-AC group, at shorter median duration. The type of prior AC differed between groups. Antiplatelet therapy (54%) and major bleeding prior index (13%) were more frequent in the No-AC group. There was a median [IQR] of 4 [0-60] and 4 [1-26] days of grade 3-4 thrombocytopenia in the No-AC and Continue-AC groups, respectively. Platelet nadirs (x10 9/L) were numerically higher in the No-AC group (31 [3-50] vs. 21 [6-50]; p=0.09). A median [IQR] of 12 [6-17.25] and 10 [5-12] platelet transfusions were given to 29 (32.2%) patients in the No-AC group and 11 (26.8%) in the Continue-AC group, respectively (p&gt;0.2). In the Continue-AC group, AC was subsequently held in 12/41 (29%) and dose-reduced in 4/41 (10%) during the 30 days post-index. The 30-day cumulative incidence [95% CI] of the composite outcome (major bleeding or ATE) was 10% [4.88-17.27] in the No-AC group and 4.88% [0.86-14.7] in the Continue-AC group (HR 2.142 [0.47-9.609]). The 30-day cumulative incidence of ATE (Figure 1A) was 3.33% [0.88-8.66] in the No-AC group (n=3), and 4.88% [0.85-14.7] in the Continue-AC group (n=2), corresponding with a HR of 0.70 [0.12-4.10]. The 30-day cumulative incidence of major bleeding (Figure 1B) was 7.8% [3.40-14.52] in the No-AC group, and 2.44% [0.18-11.22] in the Continue-AC group (HR 3.29 [0.42-26.04]). The 30-day overall survival was 64.4% in the No-AC and 73.2% in the Continue-AC groups (HR 1.39 (95% CI 0.7-2.76). Conclusions: In a cohort of cancer patients with grade 3-4 thrombocytopenia (&lt;50x10 9/L) and AF (median CHA 2DS 2-VASc = 4), the majority had anticoagulation held. Baseline thrombotic and bleeding risk factors were generally balanced, but a higher rate of prior bleeding and lower rates of anticoagulation prior index in the No-AC group, suggest confounding by indication. No statistically significant difference in outcomes was detected between management groups, but 95% CI's were wide. The high bleeding and low ATE incidence in the No-AC group suggests that holding AC during time-limited periods of grade 3-4 thrombocytopenia may be a reasonable approach in many cancer patients with AF. Continuing AC should be investigated in a subset of patients with lower bleeding and higher thrombotic risk. Figure 1 Figure 1.

Background: Haploidentical stem cell transplantation (Haplo HSCT) has emerged in the past three decades as an alternative curative option when an HLA match donor is not available. Over time, the use of Haplo has increased dramatically, reaching superimposable results when compared to unrelated and related HSCT strategies, confirming its validity. The widespread use of Haplo mainly relies upon technical advances, control of alloreactivity through graft-versus-host disease (GvHD) prophylaxis combined with a rapid and almost universal probability to find an Haplo donor for any candidate patient. The aim of our study was to provide a picture of acute (aGvHD) and chronic GvHD (cGvHD) incidence in Haplo HSCT across different platform in the past 15 years, where Haplo moved from ex-vivo T-cell depleted (TCD) platform to in-vivo TCD platform to the post-transplantation cyclophosphamide (PTCy). Methods: We compared the outcomes of adult patients receiving a 1st Haplo HSCT for any hematological malignancy according to GvHD prophylaxis - ex-vivo + in-vivo TCD (n=160), in-vivo only TCD (n=507) or PTCy (n=2593) - and reported to the EBMT registry in 2004-2016. Patients with missing data on disease status at last follow-up and GvHD information were excluded. Primary endpoint was GvHD-free & Relapse-free survival (GRFS) with events defined by death or relapse or grade ≥3 aGvHD or extensive (ext) cGvHD. Secondary endpoints were progression-free survival (PFS), overall survival (OS), aGvHD and cGvHD, incidence of relapse (IR) and non-relapse-mortality (NRM). Due to sample size in the first cohort of ex-vivo TCD, multivariate analysis compared only in-vivo TCD vs PTCy cohorts. Table 1 illustrates patients' characteristics. Results: Univariate analysis for 3-year outcomes are reported on table 2. PTCy provides better GRFS, OS, PFS, NRM versus ex-vivo or in-vivo. IR was not significantly different. Likewise, the 3-year CI of cGvHD and ext cGvHD were similar between PTCy, in vivo TCD and ex-vivo TCD (cGvHD 27% [25-29%], 25% [21-29%], 18% [12-25%], p 0.03; ext cGvHD 11% [10-12%], 10% [8-13%], 8% [4-13%], p 0.45). On the contrary the 100-day CI of grade ≥2 aGvHD were lower in the ex-vivo TCD vs PTCy and in-vivo TCD (19% [14-26%], 28% [26-30%], 32% [28-36%], p 0.002) while grade ≥3 aGvHD were lower in the PTCy group vs ex-vivo and in-vivo TCD (9% [8-10%], 11% [7-17%], 14% [11-18%], p &lt;0.001). After adjustment for diagnosis, patient age, disease status, Karnofsky PS, donor/patient gender and CMV, cell source, conditioning intensity, previous auto and year of transplant, the multivariable model comparing in-vivo TCD and PTCy showed better outcome for PTCy. Compared to in-vivo TCD, the hazards for GRFS was 0.76 for PTCy (p 0.004), the HR for PFS was 0.71 (p 0.001) and the HR for OS was 0.7 (p 0.0008), the HR for NRM was 0.63 (p 0.001). Moreover, compared to in-vivo TCD, PTCy yielded similar hazards for grade≥2 aGvHD (HR: 1.02, p 0.89), grade≥3 aGvHD (HR 0.79, p 0.27), cGvHD (HR 1.17, p 0.37), ext cGvHD (HR 1.18, p 0.52) and relapse (HR 0.8, p 0.1). Variables associated with GRFS were active disease, Karnofsky PS ≥90%, diagnosis, donor/patient gender and CMV. An ancillary analysis evaluating the stem cell source effect in the PTCy cohort only, demonstrates comparable outcome endpoints (OS, PFS, NRM, IR) at 2-year between bone marrow (BM) and peripheral blood (PB) PTCy. In univariate analysis GRFS and the 2-year CI of cGvHD were not different between BM and PB (GRFS 47% [45-50%], 46% [44-49%], p 0.085; 2-year CI of cGvHD 25% [23-28%], 27% [25-30%], p 0.2) while ext cGvHD, 100-day CI of grade ≥2 aGvHD and grade ≥3 aGvHD were lower in BM PTCy vs PB PTCy (ext cGvHD 8% [7-10%], 12% [10-14%], p &lt;0.001; grade ≥2 aGvHD 20% [18-22%], 36% [33-38%], p &lt;0.001; grade ≥3 aGvHD 6% [5-7%], 12% [10-14%], p &lt;0.001). Compared to BM PTCy, the HR for cGvHD was 1.55 for PB PTCy (p 0.001), the HR for ext cGvHD was 2.04 (p 0.0003), the HR for grade ≥2 aGvHD was 1,94 (p &lt;0.0001), the HR for grade ≥3 aGvHD was 2.01 (p 0.0001). Conclusions: In the present EBMT registry study on more than 3000 patients transplanted from an Haplo donor, we report improved outcome (better GRFS - in spite of comparable chronic GvHD - OS and PFS, lower NRM) and widespread use in different diagnosis setting other than acute leukemia in PTCy platform. PTCy strategy provides a concrete progress into the field: even if cGvHD still represent a major issue, exploitation of BM PTCy seems to protect against most severe GvHD manifestation.

Introduction: Reduced-intensity and non-myeloablative (RIC/NMA) conditioning regimens are frequently used in alloHCT for NHL, because they are associated with decreased non-relapse mortality (NRM) risk in comparison with myeloablative conditioning regimens and allow older patients and patients with comorbidities to receive alloHCT. However, the optimal RIC/NMA regimen in allo-HCT for NHL is not known. Using the CIBMTR database we compared the transplant outcomes between the commonly used RIC/NMA regimens in NHL. Methods: 1823 adult (≥18 years) NHL patients in CIBMTR registry undergoing alloHCT using matched related or unrelated donors, between 2008-2016 were included. Analysis was limited to patients receiving four commonly used RIC/NMA regimens: fludarabine/ i.v. busulfan (6.4mg/kg) (Flu/Bu), fludarabine/melphalan (140mg/m^2) (Flu/Mel 140), fludarabine/cyclophosphamide (Fly/Cy) and Flu/Cy with 2Gy Total Body Irradiation (Flu/Cy/TBI). Graft-versus-host disease (GVHD) prophylaxis was limited to calcineurin inhibitor-based regimens. Patients who received post transplantation cyclophosphamide for GVHD prophylaxis were excluded. The primary outcome was overall survival (OS). Secondary outcomes included cumulative incidence of NRM, relapse, progression-free survival (PFS) and cumulative incidence of acute and chronic GVHD. Probabilities of OS and PFS were calculated using the Kaplan-Meier estimator. Multivariable regression analysis was performed for GVHD, relapse/progression, NRM, PFS, and OS. Covariates with a p&lt;0.01 were considered significant. Results: The study cohort was divided into 4 groups; Flu/Bu (n=458), Flu/Cy/TBI (n=89), Flu/Mel 140 (n=885) and Flu/Cy (n=391). The baseline characteristics are shown in Table 1. The 4 cohorts were comparable with respect to median patient age, gender, donor type, remission status at alloHCT, and use of prior auto HCT. There was no interaction between NHL histological subtype and type of conditioning regimen. Results of multivariate analysis are shown in Table 2. The Flu/Mel 140 regimen was associated with a higher NRM (HR 1.78, 95% CI 1.37-2.31; p&lt;0.001) when compared to Flu/Bu. Although the risk of relapse with Flu/Mel 140 was lower when compared to Flu/Bu (HR 0.79, 95% CI 0.66-0.94); p=0.007), this did not result in an improvement in PFS. Moreover, the Flu/Mel 140 cohort had an inferior OS (HR 1.34, 95% CI 1.13-1.59; p&lt;0.001) when compared to Flu/Bu. There was no significant difference in terms of OS, PFS, relapse and NRM between Flu/Bu, Flu/Cy and Flu/Cy/TBI. There was no difference in risk of grade 3-4 acute GVHD across the four cohorts and compared to Flu/Cy/TBI, Flu/Mel 140 had a higher risk of chronic GVHD (HR 1.38, 95% CI 1.15-1.65; p&lt;0.001). Four year adjusted PFS was 38% for Flu/Bu, 51% for Flu/Cy/TBI, 39% for Flu/Mel 140 and 35% for Flu/Cy (p=0.07). Four year adjusted OS was 58% for Flu/Bu, 67% for Flu/Cy/TBI, 49% for Flu/Mel 140 and 63% for Flu/Cy (p&lt;0.001). Disease relapse was the most common cause of death across all 4 cohorts. Conclusion: This is the largest analysis comparing the impact of various RIC/NMA conditioning regimens on the outcomes of NHL patients undergoing alloHCT. We report that the choice of RIC/NMA conditioning regimen significantly impacted OS. The most commonly used conditioning regimen, Flu/Mel 140 was associated with a higher NRM and an inferior OS. The Flu/Bu, Flu/Cy, and Flu/CY/TBI conditioning regimens appear to provide comparable OS.

Abstract Abstract 165 Introduction. The opportunity to discontinue kinase inhibitor therapy while maintaining a deep remission is desirable for many CML patients. Despite good responses to imatinib for most patients, treatment related side effects remain problematic and can affect quality of life. Studies have demonstrated that a proportion of carefully selected patients can sustain response after imatinib discontinuation. The first requirement for successful discontinuation is likely to be stable deep molecular response based on a sensitive RQ-PCR assay. The criteria for patient selection in the French Stop Imatinib (STIM) and Australian CML8 (TWISTER) imatinib discontinuation trials included stable undetectable BCR-ABL1 transcripts for at least 24 months with a PCR sensitivity of 5 and 4.5 log, respectively. The probability of continued remission after discontinuation for imatinib treated patients without prior interferon-α therapy was approximately 33%. It is not known how many imatinib treated patients will eventually meet these PCR criteria for a discontinuation trial. Aims. We aimed to determine 1) the cumulative probability of achieving the PCR criteria for imatinib discontinuation as defined in the CML8 study, and 2) factors that predicted its achievement. Method. The molecular response of 415 de-novo CML patients in chronic phase enrolled in consecutive clinical trials of imatinib since July 2000 was examined. The assigned daily imatinib dose was 400 mg for 90 patients, 600 mg for 202 patients and 800 mg for 123 patients. Molecular data were included until imatinib cessation or last follow-up. The minimum time since commencing imatinib was 30 months and the median time on imatinib was 45 months, range 3 to 136. The CML8 PCR criteria for imatinib discontinuation were confirmed undetectable BCR-ABL1 transcripts at a sensitivity of 4.5 log that remained undetectable on all PCR tests for at least 24 months while on imatinib therapy. In the current analysis the CML8 PCR discontinuation criteria are defined as ‘stable UMR4.5'. Results. At 8 years of imatinib therapy the cumulative incidence of stable UMR4.5 was 43%, Figure A. Patients were divided into groups according to the time to a confirmed major molecular response (MMR): by 3, 6, 12 or 18 months. There was a significant difference in stable UMR4.5, P<.001, Figure B. The cumulative incidence of stable UMR4.5 was more than 60% for all patients who achieved MMR by 12 months and only 16% for patients with MMR between 12 and 18 months. The time to a confirmed MMR influenced the time to reach a stable UMR4.5 after achieving MMR. Considering only patients who achieved stable UMR4.5, patients achieving MMR by 3 months took a further 39 months (median) to achieve stable UMR4.5. For those with MMR by 6 months and 12 months, the median month to a stable UMR4.5 was 50 and 76 months after MMR, P<.001. This suggests slower dynamics of BCR-ABL1 decline with delayed time to MMR. 52 patients achieved MMR after 18 months and none achieved a stable UMR4.5 by 8 years: median time to MMR was 27 months, range 21–87. Factors at the time of commencing imatinib (baseline) were examined for their association with stable UMR4.5; Sokal risk, age, sex, assigned imatinib dose and baseline BCR-ABL1 value, as well as the 3 month BCR-ABL1 value. Quantitative factors were categorized into groups, with cut-offs set at the median for age and quartiles for the baseline BCR-ABL1 value. By univariate analysis the only baseline factor that predicted for higher cumulative incidence of stable UMR4.5 at 8 years was female versus male, 68% versus 30%, P<.001, Figure C. During imatinib therapy females had significantly lower median BCR-ABL1 values at every assessment up to 42 months. The 3 month BCR-ABL1 value also predicted stable UMR4.5, P<.001, Figure D. Baseline and 3 month factors were entered into a multivariate analysis. The 3 month BCR-ABL1 value and sex were independent predictors of stable UMR4.5, P=.004 and P=.005, respectively. Conclusion. The time to achieve an MMR, sex and the 3 month BCR-ABL1 value predicted stable undetectable BCR-ABL1 while on imatinib. Lower BCR-ABL1 values and higher rates of stable UMR4.5 in females could be related to better drug adherence or biological differences. Further studies are indicated. Early MMR led to early achievement of the discontinuation criteria. The findings justify the focus on early achievement of MMR as a strategy to maximize recruitment to discontinuation studies.

Abstract The mTOR inhibitor sirolimus has been used in the prevention and treatment of GVHD after allogeneic hematopoietic stem cell transplantation (HSCT). In parallel, mTOR inhibitors have demonstrated clinical activity against various lymphoma histologies. In a retrospective study, we found that patients with lymphoma undergoing reduced intensity conditioning (RIC) HSCT who received a sirolimus-containing GVHD prophylaxis regimen had a lower rate of relapse (Armand et al, J Clin Oncol. 2008;26(35):5767). We therefore performed a multicenter, phase III, open label randomized trial comparing tacrolimus, sirolimus and methotrexate (Tac/Sir/Mtx, with sirolimus starting on day -3 of HSCT) for GVHD prophylaxis to conventional sirolimus-free regimens (tacrolimus + methotrexate (Tac/Mtx) or cyclosporine + MMF (Csa/MMF), pre-specified by center), in patients undergoing RIC HSCT for any lymphoma except Burkitt lymphoma. The primary endpoint was 2-year overall survival (OS); progression-free survival (PFS), acute and chronic GVHD were among the secondary endpoints. 139 patients were enrolled at five institutions between June 2009 and September 2012. The median age was 57 years (range, 23-70). 42 patients had aggressive B-NHL, 31 indolent B-NHL, 28 CLL, 19 T-NHL and 19 Hodgkin lymphoma. 66 were assigned to the Tac/Sir/Mtx arm, and 73 to the control arm (67 to Tac/Mtx and 7 to Csa/MMF). All patients but 1 received the allocated intervention, and all received peripheral blood stem cell products, as mandated by the protocol. Based on a planned interim analysis, the DSMB recommended reporting of the interim results at this time. Median follow-up for survivors is 22 months, and only 12% of living patients have less than 12 months of follow-up. There was no evidence of increased toxicity in the Tac/Sir/Mtx arm. At the time of this analysis, the Kaplan-Meier estimate of 2-year OS by intent to treat (Figure 1A) is 66% (95CI, 51-77) in the Tac/Sir/Mtx arm vs. 71% (95CI, 58-81) in the control arm (p=0.7); the corresponding 2-y PFS (Figure 1B) is 62% (95CI, 48-73) vs. 56% (95CI, 43-68) (p=0.9). The conditional power for finding a significant difference in the primary endpoint of 2y OS is <1%, prompting the current report. There was no significant difference in non-relapse mortality (2y cumulative incidence 14% in both groups, p=0.9) or cumulative incidence of relapse (2y incidence 25% vs. 30%, p=0.8). However, the addition of sirolimus resulted in a significant decrease in the cumulative incidence of grade 2-4 acute GVHD (6-month cumulative incidence 9% vs. 25%, p=0.014; Figure 1C), even after excluding patients who received Csa/MMF. This was apparent in both patients receiving matched related and those receiving matched unrelated grafts. There was no significant difference in the incidence of grade 3-4 acute GVHD (3% vs. 4% at 6 months, p=0.7) or chronic GVHD (2-year cumulative incidence 59% vs. 55%, p=0.5; Figure 1D).Figure 1Figure 1. In conclusion, the addition of sirolimus to the GVHD prophylaxis regimen in patients with lymphoma undergoing RIC HSCT is associated with a significant decrease in grade 2-4 acute GVHD after transplantation, without impacting toxicity, severe acute GVHD, chronic GVHD, progression-free or overall survival. These results should be broadly applicable to all recipients of RIC HSCT using T-cell-replete peripheral blood stem cells, and suggest that tacrolimus, sirolimus and methotrexate could be a preferred regimen in this patient population. Pre-specified subgroup analyses by histology and correlative studies will be performed when follow-up is complete in late 2014.

Abstract Background: While many studies have attempted to compare different GVHD prophylaxis within the reduced intensity conditioning allogeneic stem cell transplant setting (RIC SCT), few studies have been performed comparing different conditioning regimens. Due to the lack of evidence on the best RIC, the selection of the conditioning regimen is mainly based on the experience from each institution. In this study, we compared the outcomes of patients undergoing RIC SCT in 2 different settings: the Spanish Group of Transplantation (GETH), where fludarabine + melphalan (FluMel) has been the standard RIC in patients with lymphoid malignancies and Dana-Farber Cancer Institute/Brigham and Women's Hospital (DFCI/BWH), where fludarabine + busulphan (FluBu) is the standard RIC. Patients and methods: We analyzed the outcomes of 136 patients diagnosed with lymphoma undergoing RIC with either FluBu (n=61) or FluMel (n=75) in the GETH or at DFCI/BWH between 2007 and 2014. Patient characteristics are shown in table 1. The following variables were included into the multivariable analysis: type of conditioning, GVHD prophylaxis, type of donor, age, previous transplant, and disease risk index (DRI) based on diagnosis and disease status at transplant. Median follow-up was 36 months. Results: The cumulative incidence of grades 2-4 acute GVHD was 13% vs 36% among patients receiving FluBu vs FluMel, respectively (p=0.002). In multivariable analysis only the type of conditioning significantly influenced the risk of grades 2-4 aGVHD [HR with FluMel 7.35, (95% CI= 2.27-23.8), p=0.0008]. The cumulative risk of non-relapse mortality at 1 year was 3.3% vs 31% for FluBu vs FluMel, respectively (p<0.001). In multivariable analysis again only type of conditioning significantly influenced the risk of NRM [HR with FluMel 5.61, (95% CI= 1.57-20.03), p=0.007]. The 1y cumulative incidence of relapse was 29% with FluBu vs 10% with FluMel (p=0.08). In multivariable analysis, only prior transplantation and donor type were associated with the risk of relapse. The 3-year disease-free survival in patients receiving FluBu was 55%, vs 40% for those receiving FluMel (p=0.24). Only donor type was significant in the DFS in multivariable models. Finally, the 3y OS in the BuFlu group was 72% vs 50% for those receiving FluMel (p=0.01) (fig 1). Conditioning regimen was the only factor significantly associated with OS in multivariable analysis, HR with FluMel 2.87, (95% CI= 1.28-6.43), p=0.01]. Conclusion: In this retrospective study of patients who received a RIC SCT for lymphoma, the use of FluBu as compared to FluMel was associated with a significant decrease in non-relapse mortality and an improvement in overall survival. Acknowledging the limitations associated a retrospective study, but in the absence of prospective randomized data, our results lend support to the choice of FluBu as a conditioning regimen in this setting.

Background:The goal of treatment in rheumatoid arthritis (RA) is to achieve remission. There is the patient with residual symptoms in the Japanese RA patient who achieved clinical remission. There are not many studies to examine the relation between everyday life, social activity and evaluation of disease activities using high-sensitivity image examinations (musculoskeletal ultrasound (MSKUS) and MRI).Objectives:To examine the relationship between subjective residual symptoms and imaging examinations in RA patients who have achieved clinical remission.Methods:30 RA patients who achieved SDAI remission during RA treatment. Age, sex, disease duration, physical findings, serological markers, disease activity, HAQ, EQ-5D-5L, FACIT-F, Patient Reported Outcomes (PROs), EGA and medications were evaluated. 44 joints were assessed by MSKUS with gray scale (GS) and power doppler (PD) and contrast-enhanced bilateral joint MRI scoring with OMERACT-RAMRIS scoring.Results:1. The mean SDAI of the 30 RA patients was 1.3. 2.In the analysis of the presence or absence of subjective residual symptoms that led to remission of SDAI (Table 1).Table 1.Subjective residual symptoms/presence (N=17)Subjective residual symptoms/absence (N=13)Univariate analysisp valueMultivariate logistic analysisp valueTJC0.0±0.00.3±0.50.0173HAQ0.4±0.40.05±0.10.00950.00181EQ5D-5L0.8±0.10.9±0.00.0001FACIT-F14.5±9.84.6±4.30.0233Morning stiffness (min)256.5±564.80.0±0.00.0210Pain (VAS) (mm)9.2±9.50.9±1.50.00440.0455PGA (mm)7.7±9.00.5±1.10.0013(1). In the univariate analysis, the number of tender joints, HAQ, EQ-5D-5L, FACIT-F, morning stiffness, and pain VAS were extracted with significant differences.(2). In multivariate logistic analysis, HAQ and pain VAS were extracted as independent factors with significant differences. 3.In univariate analysis of the association between HAQ and pain VAS extracted in multivariate logistic analysis and imaging examinations (MSKUS/MRI), MRI-synovitis was extracted with a significant difference in HAQ.Conclusion:1. It was suggested that Pain VAS and HAQ due to RA could be identified in patients reaching SDAI remission. 2. In patients reaching SDAI remission, Pain VAS ≤10 or HAQ ≤0.5 suggested that subjective residual symptoms may be eliminated. 3. HAQ ≤ 0.5 suggests that synovitis is less likely to be detected on MRI. 4. In patients who have reached SDAI remission, little residual inflammation was observed on US, suggesting that induction of remission is important not only to prevent joint destruction, but also to improve and maintain long-term QoL.Disclosure of Interests:MASAO NAWATA Grant/research support from: I have received research funding from Eli Lilly Japan K.K., Kazuki Someya: None declared, Takafumi Aritomi: None declared, Masashi funada: None declared, Katsumi Nakamura: None declared, SAITO KAZUYOSHI Grant/research support from: I have received research funding from Eli Lilly Japan K.K., Yoshiya Tanaka Speakers bureau: I have received speaking fees from Abbvie, Daiichi-Sankyo, Chugai, Takeda, Mitsubishi-Tanabe, Bristol-Myers, Astellas, Eisai, Janssen, Pfizer, Asahi-kasei, Eli Lilly, GlaxoSmithKline, UCB, Teijin, MSD, and Santen, Consultant of: I have received consulting fees from Abbvie, Daiichi-Sankyo, Chugai, Takeda, Mitsubishi-Tanabe, Bristol-Myers, Astellas, Eisai, Janssen, Pfizer, Asahi-kasei, Eli Lilly, GlaxoSmithKline, UCB, Teijin, MSD, and Santen, Grant/research support from: I have received research grants from Mitsubishi-Tanabe, Takeda, Chugai, Astellas, Eisai, Taisho-Toyama, Kyowa-Kirin, Abbvie, and Bristol-Myers

Background: The use of post-transplant cyclophosphamide (PTCy)/tacrolimus/mycophenolate mofetil (MMF) for GVHD prophylaxis has improved outcomes in haploidentical hematopoietic cell transplantation (haplo-HCT). PTCy is now being evaluated in matched-related (MRD) and matched-unrelated (MUD) allo-HCT. Previous studies demonstrated improved GVHD-free/relapse-free survival (GRFS) when PTCy was combined with two immunosuppressive agents and PTCy has also been associated with better relapse-free survival (RFS) as demonstrated in De Jong et al 2019, though only one immunosuppressive agent was used. Currently, there is limited published data comparing outcomes using PTCy/tacrolimus/MMF to standard MRD/MUD GVHD prophylaxis of methotrexate (MTX)/tacrolimus. The importance of studying this comparison may help to improve GVHD outcomes in MRD and MUD allo-HCT. Methods: We retrospectively analyzed adult patients at USC Norris Cancer Hospital (age ≥ 19) who received allo-HCT from 2018 to 2020. The primary end-points assessed were incidence and severity of 1-year aGVHD and cGVHD. Secondary end-points included day+100 mortality, 1-year overall survival (OS), 1-year RFS, 1-year transplant-related mortality (TRM), and 1-year GRFS, defined as grade 3-4 acute GVHD, systemic therapy-requiring chronic GVHD, relapse, or death in the 1-year post-HCT period. Results: A total of 65 adult MRD and MUD allo-HCT recipients and 53 haplo-HCT patients were reviewed. Of the MRD/MUD patients evaluated, approximately 51% (n = 33) were female and 49% (n = 32) were male. The age range was 20-69 years old (median = 46), and the most common diseases included ALL (46%), AML (31%), MDS (11%), and others (i.e. lymphoma, aplastic anemia (AA), myelofibrosis) (12%). 34% (n = 22) of patients received PTCy on D+3 and D+4 with tacrolimus/MMF/ on D+5 as GVHD prophylaxis and 66% (n = 43) of patients received MTX/tacrolimus on D+1, +3, +6, and +11 as GVHD prophylaxis. All haplo-HCT patients received standard PTCy/tacrolimus/MMF. Stem cell source was primarily PBSC except in HLH and AA patients. The PTCy group had more MUD allo-HCT (64%), degree of antigen mismatch (56%), and median age of 50.5 years compared with the MTX group at 44%, 47%, and 44 years respectively. 70% in the MTX group received MAC compared with 45% in the PTCy group. The haplo group had similar demographics to the MTX group. The mean CD34 cell doses in the PTCy, MTX, and haplo groups were 4.87, 5.36, and 7.24x106 cells/kg respectively. Incidences of total GVHD, aGVHD, and aGVHD grade 3 or 4 in the PTCy group were 55%, 50%, and 4.5% respectively compared with 65%, 35%, and 7% in the MTX group, though not significant. The haplo group had 68%, 55%, and 1.9% respectively. Incidence of total cGVHD and cGVHD requiring systemic therapy in the PTCy group was 4.5% and 0% respectively compared with 30% (p = .02) and 23% (p =.01). The haplo group had 13% and 1.9% respectively. Day+100 mortality, 1-year OS, 1-year RFS, 1-year TRM, and 1-year GRFS in the PTCy group were 0%, 80%, 60%, 0%, and 64% respectively compared with 7%, 88%, 90%, 7.3%, and 59%. The haplo group had 3.8%, 86%, 89%, 14%, and 66%. In a univariate analysis, factors significantly associated with GVHD were disease status (p = .0.12) and CD34 dose (p = 0.015) and antigen mismatch (p = 0.04) was associated with increased mortality. Discussion: Our results demonstrate improved overall and extensive cGVHD outcomes in the PTCy group and thus an improvement in 1-year GRFS. Furthermore, incidence and severity of 1-year cGVHD in this group are improved when compared with previously reported outcomes. 1-year GRFS reported in De Jong et al 2019 was 45% and 1-year GRFS reported for all groups in our study is higher at 66%, 64%, and 59% for the haplo, PTCy, and MTX groups respectively. Although this was not significant, it may be clinically meaningful given the significant improvement in extensive GVHD and improvement in all other secondary end-points except 1-year OS and RFS. Furthermore, the PTCy group had a higher percentage of mismatched antigens yet demonstrated superior outcomes. 1-year OS and RFS were superior in the MTX group however this is likely due to sample size differences. The improved extensive cGVHD and GRFS outcomes observed using PTCy/tacrolimus/MMF in the MRD/MUD setting should continue to be evaluated and currently there is an ongoing prospective, randomized study to further investigate.
