Abstract Abstract 1975 Background: Among patients with AML with normal cytogenetics (CN-AML), the presence or absence of the NPM1 mutation (NPM1mut) and the FLT3 internal tandem duplication (FLT3-ITD) allows to define molecular subgroups, which proved to influence leukemia-free survival (LFS) both after chemotherapy and allo-SCT (Schlenk, NEJM 2008, Brunet, JCO 2012). Hence, the genotypes are currently used as “disease risk” criteria, especially to define indication for allo-SCT in CR1. The influence of these markers on overall survival (OS) after allo-SCT has not been evaluated so far. Methods: An EBMT registry-based analysis included adults fulfilling the following criteria: CN-AML, peripheral blood stem cell or bone marrow allo-SCT in CR1 between 2006 and 2011, using matched-related (MRD) or matched unrelated donor (MUD), and detailed information on the mutational status of NPM1 and FLT3-ITD being available. OS, LFS, relapse incidence (RI) and non-relapse mortality (NRM) were calculated according to molecular subgroups. Further, a multivariate Cox model for risk factors was applied, including the following, predefined variables: Age (<> median), white blood cell counts at diagnosis, time from diagnosis to CR1, donor type (MRD versus MUD), conditioning regimen (reduced versus standard) and presence or absence of NPM1mut and FLT3-ITD. Results: 366 patients (median age: 49.5 years, range 18.0–70.6; 49% males, MRD in 54%) were included. Median time from diagnosis to CR1 was 45 days (range: 7–181), and median time from CR1 to allo-SCT was 109 days (range: 11–308). Median follow-up from allo-SCT was 12 months (range: 1–61). The Kaplan-Meier estimates of 2-year OS and LFS for the entire cohort were 69±3% and 62±3%, the cumulative incidence of relapse and NRM were 23±2% and 14±2%. Presence of an NPM1mut had no influence on LFS or OS. In contrast, presence of an FLT3-ITD was strongly associated with increased RI (p=0.0004), and decreased LFS (p=0.004) and OS (p=0.0007). Results at 2 years from allo-SCT (% +/− SD) according to molecular subgroups are shown in the table below (mut, mutated, WT, wild type): In the multivariate Cox model, age above the median of 49.5 years was the only factor associated with increased NRM (HR= 3.15, 95%CI: 1.27–7.82, p=0.01), whereas FLT3-ITD was the only factor that correlated with RI (HR=2.80; 95%CI; 1.26–6.20, p=0.01). Both older age and presence of FLT3-ITD were significantly associated with inferior LFS (HR=1.73, 95%CI: 1.03–2.91, p=0.04 for age, HR=2.03, 95%CI: 1.13–3.65, p=0.02 for FLT3-ITD) and, most importantly, with decreased OS (HR=2.29; 95%CI: 1.27–4.15, p=0.006 for age, and HR=2,75; 95%CI: 1.41–5.34, p=0.003 for FLT3-ITD). The latter data allowed the development of a scoring system, identifying three prognostic groups with 2-year survival rates of 42+/−7% (patients with both older age and FLT3-ITD), 66+/−4% (older age or FLT3-ITD) and 74+/−7% (younger age and FLT3-ITDneg, p<0.0001), respectively. Conclusion: We conclude that older age and FLT3-ITD are major risk factors for OS after allo-SCT in CN-AML patients in CR1, independently from other factors such as donor type, intensity of the conditioning, or NPM1 mutational status.

Abstract A landmark study from Medical Research Council/Eastern Cooperative Oncology Group showed improved survival (∼53%) for patients allocated to sibling HCT versus either consolidation/maintenance chemotherapy or autologous HCT. Matched unrelated donors (MUD) are an option for patients without a SIB available and we retrospectively analyzed disease outcomes after SIB and MUD in adult ALL patients. Between 2001and 2012, 204 adult ALL patients with a median age of 36 years (range, 18-64) were transplanted with a SIB (n=112) or 8/8 MUD (n=92). Disease status at HCT was first or second complete remission and beyond (CR1, n=113, 55.5% and CR2+, n=91, 44.5%). Conditioning was myeloablative in 177 (86.8%) and reduced intensity (RIC) in 27 patients (13.2%). All but 2 patients received graft versus host disease (GVHD) immunosuppression with tacrolimus and methotrexate. Patient and disease characteristics including age, sex, histological subtypes and high risk disease features (WBC and cytogenetic classification at diagnosis), disease status at HCT and conditioning intensity were similar between SIB and MUD recipients. As expected, MUD patients had bone marrow (BM) as the stem cell source more commonly than SIB (69.6% vs. 7.1, p&lt;0.001). The median follow-up of 96 survivors was 36 months. The univariate point estimates at the stated timepoints and multivariate outcomes are summarized in the Table1 and 2.Table1The summary outcomesSIB (%)MUD (%)PNeutrophil recovery at day 4296.497.80.6Platelet recovery at day 1009281.50.03Grade II-IV aGVHD30.248.30.0093 year TRM in CR124.628.70.63 year TRM in CR2+21.023.10.83 year relapse incidence in CR124.420.60.63 year relapse incidence in CR2+49.939.60.33 year OS in CR155.955.60.83 year OS in CR2+33.137.90.8Table 2Multivariate results for OS*HR95%CIPCR1RefCR21.71.1-2.50.01Age &lt;35RefAge&gt;=351.71.1-2.60.01*Adjusted for cytogenetics and WBC at diagnosis, donor type and conditioning intensity.Figure 1Overall survival by disease status and donor typeFigure 1. Overall survival by disease status and donor type In summary, hematopoietic transplantation using a MUD was associated with slower platelet recovery which could be due to more common use of BM as the stem cell source. Acute GVHD incidence was also higher with MUD transplants but OS was comparable between donor types, even when patients were transplanted in CR1. Thus, in the absence of a SIB donor, a matched unrelated donor is an acceptable donor source for HCT with comparable overall survival.

Abstract Background Allogeneic stem cell transplantation (alloSCT) is the only curative treatment for most patients with CN AML. It is now well established that some relevant molecular markers can allow for the definition of risk groups after conventional chemotherapy. However, the role of these markers among other factors influencing outcome after alloSCT remains to be defined. Hence, we conducted an EBMT registry-based analysis aiming to define the exact prognostic role of molecular subgroups in conjunction with other classical risk factors after alloSCT for CN-AML. Patients, Methods and Results 752 adults (375 males) fulfilled the inclusion criteria, i.e. first alloSCT for CN-AML between 2000 and 2011, matched sibling (MSD) or unrelated (MUD) donor, and known mutational status of FLT3-ITD and NPM1, the two most frequently observed molecular markers in CN-AML. Median age was 51y (range, 18-71), disease status at time of alloSCT was CR1 (n=554), CR2/3 (n=90), primary induction failure (PIF, n=39), relapsed disease (n=62) and unknown (n=7). Myeloablative and reduced-intensity conditioning regimens were used in 371 and 378 patients, respectively. 597 received allogeneic PBSCs. With a median follow-up of 27 months, The 2-year estimates of overall survival (OS) and leukemia-free survival (LFS) were respectively 68±2% and 61±6% after alloSCT in CR1, 63±2% and 53±6% in CR2/3, 36±7% and 33±8% in PIF, and 28±7% and 25±6% in relapsed disease. In 554 patients transplanted in CR1, OS, LFS, cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) were calculated according to molecular subgroups. Whereas NPM1mut had no influence on outcome, FLT3-ITD was associated with increased CIR (p<0.0001), decreased LFS (p=0.0002) and OS (p=0.0006) Outcome after alloSCT of subgroups based on mutational status of NPM1 and FLT3-ITD is shown in table 1 . A multivariate Cox model of predefined risk factors including age, WBC at diagnosis, time to reach CR1, donor type, conditioning type (reduced vs. standard), and presence of NPM1mut and FLT3-ITD, was performed. Age >=50 years was the only risk factor for NRM (HR= 2.40, 95%CI: 1.32-4.37), while the presence of FLT3-ITD was the only risk factor for CIR (HR=2.85; 95%CI; 1.76-4.60). Both age >=50 years and FLT3-ITD were associated with inferior LFS (HR=1.65, 95%CI: 1.14-2.39, p=0.01 for age, HR=2.08, 95%CI: 1.43-3.01, p=0.001 for FLT3-ITD) and, most importantly, OS (HR=1,76; 95%CI: 1.19-2.61, p=0.005 for age, and HR=2.19; 95%CI: 1.48-3.26, p=0.0001 for FLT3-ITD). The latter data allowed to identify 3 prognostic groups with 2-years OS of 83±4% (younger age and FLT3-ITDneg), 70±4% (older age OR FLT3-ITD) and 48±5% (older age and FLT3-ITD), p<0.0001; Figure 1). On the contrary, donor type (sibling vs. MUD) or intensity of the conditioning regimen (standard vs. reduced) did not play any significant role in any molecular subgroup. Conclusion In the largest study on CN-AML performed thus far, we identified age >=50 years and FLT3-ITD as the major risk factors for OS after alloSCT in CR1, independently from other risk factors such as type of donor or conditioning. In patients harboring FLT3-ITD, a limited protective role for NPM1 mutation could be observed. These results underscore the importance of post-transplant strategies to prevent relapse in AML with FLT3-ITD. Encouraging results were observed after SCT in PIF, relapse or advanced CR.

Background:Treatment options are limited for patients (pts) with hematologic malignancies who relapse after allogeneic stem cell transplantation (allo-SCT). We hypothesized that checkpoint inhibitors may offer a novel approach for maintaining remission after allo-SCT. Data from pre-clinical studies have suggested a potential role for PD-1/PD-L1 inhibitors in acute myeloid leukemia (AML) (Zhang et al., Blood 2009), so it is possible that immunomodulation with checkpoint inhibitors could stimulate the donor anti-leukemia immune response and prevent disease relapse. However, the safety of checkpoint blockade early after allografting remains to be established. Methods:We conducted a pilot study to assess the tolerability and efficacy of Nivolumab, a PD-1 inhibitor, as maintenance therapy after allo-SCT (NCT02985554). Pts were eligible if they were post allo-SCT without evidence of relapse or active graft-vs-host disease (GVHD) or history of prior greater than stage I skin acute GVHD. Nivolumab was to be administered intravenously at 1mg/kg every 2 weeks for 4 doses followed by dosing every 12 weeks. Treatment started 4 weeks after routine immunosuppression was discontinued until 2 years after the transplant. The primary objective was to determine the tolerability of Nivolumab on this schedule. Secondary objectives were evaluation of adverse events, relapse, and overall survival. Results:Four pts were enrolled from December 2017 through November 2018. (Table 1)All pts experienced immune-related adverse events (irAE) from Nivolumab, and 2 (50%) pts experienced serious adverse events. (Table 2)One pt developed grade (G) 4 neutropenia soon after the first dose. (Figure 1)The absolute neutrophil count nadired at 20 cells/µL, at which point pegfilgrastim was administered. An interim bone marrow biopsy (BMBx) confirmed no evidence of relapsed disease. Full neutrophil recovery occurred approximately 3 months after the initial dose, and no subsequent toxicities occurred. Another pt developed G3 autoimmune encephalopathy concurrently with G2 transaminitis and G2 thrombocytopenia after one dose of Nivolumab. (Figure 2)Intravenous methylprednisolone (1mg/kg daily for 3 days) and immunoglobulin (2g/kg in 4 divided doses) were administered, followed by a 7-week steroid taper with full resolution of symptoms. Relapsed disease was ruled out by a BMBx. A third pt developed G2 skin rash approximately 10 days after the first dose of Nivolumab. Skin biopsy demonstrated drug hypersensitivity reaction vs GVHD, and the pt was treated with a 3-week prednisone course (starting at 1mg/kg followed by a taper). A mild flare recurred 2 weeks later, which was treated with topical steroids only. However, Nivolumab was not resumed. The fourth pt developed G2 elevated TSH approximately 2 months into therapy and after 4 doses of Nivolumab. Thyroid hormone replacement was initiated with subsequent symptom improvement and normalization of TSH over a 4-month period. As a result of these unexpected severe toxicities, the study was closed to further enrollment, and further Nivolumab administration ceased. Thus far, one pt (#1) relapsed after a total remission duration of 530 days; the remission duration after starting Nivolumab was 318 days. One pt has mild chronic skin GVHD. All 4 patients remain alive with a median overall survival of 2.3 years (range, 1.9-4.7). Conclusions:Even at low doses, the use of Nivolumab as maintenance therapy in the post allo-SCT setting was not tolerable at the current dosing and schedule due to an unexpected number of high grade irAEs. Additional studies of dose and timing after allo-SCT are needed to improve safety and tolerability, in conjunction with correlative studies to better understand the immunomodulatory processes in the post-transplant setting.

Abstract Introduction: The role of autologous hematopoietic stem cell transplantation (auto-HCT) in the management of patients with Waldenström Macroglobulinemia (WM), a rare, indolent lymphoma, has not been established. We had previously published our experience with auto-HCT in a small cohort of WM patients1. Here, we present an updated analysis of auto-HCT with a larger cohort of WM patients. Methods and study population: The study cohort was comprised of 29 patients who underwent high-dose chemotherapy and auto-HCT at MD Anderson Cancer Center (MDACC). The Kaplan-Meier method was used to create survival curves. Overall survival (OS) was defined as the duration from date of transplant to death or last date of follow-up in living patients. Progression-free survival (PFS) was defined as the duration from date of transplant to either progressive disease or death, whichever occurred first. Results: Median age at auto-HCT was 60 (range, 43-75 years). Eight patients (28%) had concurrent light chain amyloidosis (AL). Of the five patients who had MYD88 testing completed, 3 were positive for the MYD88 mutation. Additionally, of these 3 patients, 2 were also positive for CXCR4 mutation. Patients received a median of 2 lines (range 1-6) of therapy prior to auto-HCT; 3(10%) patients had primary refractory disease, 8(28%) were in first remission, and 18 (62%) had relapsed disease. Median time from transplant to last follow-up for the surviving patients was 5.3 years. Preparative regimens received by the patients were: Melphalan (n=20), BEAM-R (n=2), Busulfan/Melphalan (n=1), Cyclophosphomaide/Etoposide/total body irradiation (n=1), Thiotepa/Busulfan/Cyclophosphamide (n=1), and Carmustine/Thiotepa (n=1). Three patients further went on to receive allogeneic transplant either after relapse from auto-HCT or due to disease transformation to aggressive lymphoma. Twenty-eight patients achieved engraftment with a median time to neutrophil engraftment of 11 days (range, 10-15 days). One patient suffered primary graft failure due to progression of disease and died 84 days after transplant. Non-relapse mortality was 3.4% at 1 year. All patients were eligible for response evaluation. The median OS from diagnosis was 12.2 years. Overall response rate was 96%: complete response (n=8, 27.6%), very good partial response (n=5, 17.3%), partial response (n=15, 51.7%), and progressive disease (n=1, 3.4%). PFS and OS at 5 years were 43.3% and 62.9%, respectively. Median PFS and OS from auto-HCT were 4.1 and 7.3 years (Fig. 1A). The median OS from auto-HCT in first remission + primary refractory and relapsed disease was 8.2 years and 4.1 years, respectively.16 patients were alive at the time of censoring while 13 patients had died. Causes of death include relapsed disease (n=6), secondary malignancy (n=2), infection (n=1), chronic graft-versus-host disease (n=1), and unknown (n=3). 8 patients (28%) were positive for concurrent AL amyloidosis. The sites of amyloid involvement were kidneys (n=2), lungs (n=1), bone marrow (n=1), heart(n=1), lymph nodes(n=1), gastrointestinal tract (n=1) and subcutaneous fat aspirate(n=5). The median overall survival for patients with amyloid involvement (n=8) was 12 years. On univariate analyses, the number of chemotherapy regimens prior to transplant (≤ 2 vs >2 lines) was the strongest predictor of overall survival (p=0.03, HR 0.3, CI: 0.09-0.9, log-rank) and PFS (p=0.001, HR 0.24, CI: 0.07-0.85, log-rank). The median PFS in patients with ≤ 2 lines and > 2 lines of therapy was 71 months versus 19 months, respectively (Fig. 1B). Conclusion: Auto-HCT is safe and feasible in selected patients with WM, with a high response rate and durable remission even in patients with relapsed or refractory disease.

Abstract Abstract 3331 Poster Board III-219 Introduction Current data suggests that recipient age above 50 is associated with an inferior outcome after myeloablative allogeneic stem cell transplantation (SCT). Overall survival (OS) of 31%, and transplant related mortality (TRM) of 17% at 100 days have been reported in this population (Ditchkowski, et al 2005; Yanada, et al. 2004). Encouraging results are observed with non-myeloablative conditioning regimens. However, for patients with a high relapse risk, this approach may not be sufficient to achieve long term disease control. In these cases, a reduced toxicity, yet ablative stem cell transplantation (RT-SCT) may give adequate time to the transplanted cells to mature and mount an immune-mediated antitumor response. This study evaluated the outcome after RT-SCT using a conditioning regimen consisting of intravenous busulfan (Bu) and pentostatin (Pent). Methods Consented adult patients up to 70 years with a fully-matched related (MRD) or unrelated donor (MUD) were screened for enrollment. Conditioning consisted of Bu 1.6 mg/kg every 12 hours days -7 to -4, and Pent 4 mg/m2 on day -3 and -2 prior to stem cell infusion on day 0. GVHD prophylaxis was methotrexate 10 mg/m2 on day 1, and 5 mg/m2 on days 3, and 6. Tacrolimus was started on day -2, and then tapered over 1 month after day +100. Characteristics Twenty six patients were analyzed. Male to female ratio was 1:1. Stem cell source was from MRD in 15 patients and MUD in 11. Median age was 62, with 92% of patients being older than 50 years. Indications for treatment were AML (35%), MDS (42%), Refractory CLL (23%), Relapsed NHL (12%), and Philadelphia (+) ALL (4%). All AML patients were high risk either due to poor cytogenetic, transformation, or relapse and only two of them were transplanted in first complete remission. MDS patients were RAEB (36%), secondary MDS (36%), or multilineage dysplasia (18%). Two patients had prior autologous transplants. Results No graft failure was observed. All patients achieved neutrophil (NEU) engraftment. Two patients expired prior to platelet (PLT) engraftment. Median engraftment days for NEU and PLT were 13 days. At a median follow up of 25 months, the OS and progression free survival for the entire group was 40% and 38% respectively. The OS in the MRD group was 58%. TRM at 100 days was seen in one patient (4%) due to veno-occlusive disease (VOD). Limited chronic GVHD was the most common observed toxicity (54%), followed by diarrhea (30%) and mucositis (23%). Mucositis was mainly grade 1 (8%) and grade 2 (8%). No grade 3 mucositis was observed. There was only one case of VOD and one case of acute GVHD. Conclusion To our knowledge, this is the first report of a RT-SCT using BuPent. This study demonstrates the efficacy of the regimen in patients older than 50 years. No graft failure was observed and the regimen related toxicity was acceptable in this high-risk population. The overall survival of 40% at a median follow up of 25 months compares favorably with prior reports of myeloablative allogeneic stem cell transplatation in patients older than 50 years. This regimen provides an exciting opportunity to extend the benefits of allogenic transplant to an older population, and warrants replication with larger controlled trials.

Abstract Abstract 3120 Introduction: Chemo-immunotherapy (i.e. rituximab combinations) has clearly had a significant impact on the outcome of all B-cell NHL both in terms of PFS and OS. However in the relapse/refractory setting a large proportion of pts still do very poorly especially in aggressive subtypes including DLBCL and MCL. Salvage therapy followed by HDT-ASCT in relapsed DLBCL remains the standard, though pts with early failures (<1y) and/or prior exposure to rituximab still show dismal results (CORAL data). In MCL the use of HDT-ASCT in the relapse setting is debated given the frequency of chemo-resistance leading to poor results even in second CR. The use of allogeneic transplantation was developed based on observations c/w with a clear GVL effect in NHL as illustrated by pts going into remission after DLI injections. The development of non-myeloablative approaches has allowed expansion of use of allogeneic BMT in relapsed/refractory NHL. We report here one of the largest series (179 consecutive pts) with relapsed/refractory lymphoma focusing on overall survival and outcome predictors. Methods: Utilizing Kaplan-Meier survival and Cox regression methods, we report on the outcome of 179 consecutive pts with relapsed/refractory lymphoma who underwent allogeneic stem cell transplantation at the John Theurer Cancer Center between 1995–2012. The primary study endpoint was overall survival (OS) assessed by chart and SSDI database review. Secondary study endpoints included examination of the association between overall survival and allogeneic stem cell source, donor source, development of GVHD, pre-transplant chemo-sensitivity and prior failure to HDT-ASCT (second transplant). The proportional hazards assumption was met for this analysis. Results: Survival data on 179 pts (median age 48, range 20–71) were analyzed, representing 86 deaths and 5720 total months at risk (median follow up=12.3 months). Baseline characteristics included: ECOG PS (med 1, range 0–2), diagnosis (25% DLBCL, 21% HD, 20% MCL, 13% FCL, 13% PTCL, 8% other), donor source (50% matched SIB, 31% MUD, 19% mismatched MUD), stem cell source (73% PB, 23% BM, 6% Cord) and prior autologous SCT (38%). The median OS for the entire cohort was 31.2 months. OS KM curves by selected aggressive NHL subtypes are represented in Figure 1. We performed COX regression analyses to address outlined secondary endpoints. In univariate analyses statistically significant inferior outcomes were associated with the use of mismatched unrelated donor (HR 1.4, p=.01, Figure 2), bone marrow donor stem cells vs. PBSCT (HR=1.7 p=.04), pre-transplant stable/refractory disease (HR 1.8, p=.03), absence of cGVHD (HR=4.7, p<.001) and presence of acute GVHD (HR 2.8, p=.001). No difference in OS was detected whether pts had undergone allogeneic SCT as a second transplant (med time between auto/allo=20.9 months) following relapse after auto SCT (HR 1.14, CI .75–1.73, p=.5). Conclusions: This series represents a large cohort of poor risk, relapsed/refractory lymphoma pts treated consecutively with allogeneic stem cell transplantation over a > 10-year period at our institution with the following observations: Disclosures: Mato: Celgene: Speakers Bureau; Millennium: Speakers Bureau; Seattle Genetics: Speakers Bureau; Genentech: Speakers Bureau.

Abstract The major causes of mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are relapse, graft-versus-host disease (GVHD), and infection. We have previously reported that changes in the intestinal flora can affect GVHD, bacteremia, and overall survival. As intestinal bacteria are potent modulators of systemic immune responses, and since GVHD is correlated with graft-versus-tumor activity, we hypothesized that components of the intestinal flora could be associated with relapse after allo-HSCT. We applied a biomarker-discovery approach and performed a retrospective observational analysis of 160 adults who received an unmodified (T-cell-replete) allograft. Patients were prospectively enrolled in a fecal biospecimen-collection protocol. For this analysis, we selected patients who had at least one specimen during the first 3 weeks following allo-HSCT. The primary diseases in this cohort were AML (37%), Non-Hodgkin's Lymphoma (33%), ALL (8%), MDS (7%), CLL (6%), Hodgkin's Lymphoma (6%), CML (2%), and myeloproliferative neoplasm (2%). The mean age of the patients was 52 years (range 21-75). They were conditioned with ablative (17%), reduced-intensity (64%), and nonmyeloablative (19%) regimens. They received grafts from cord blood (46%), unrelated adults (33%), or related adults (22%). Among adult grafts, 92% were from peripheral blood and 8% were from bone marrow. A census of the bacterial species in each stool sample was generated by 16S rRNA deep-sequencing as previously described (Jenq et al., BiolBone Marrow Transplant 2015). The area under the curve of bacterial abundance over time was used as a measure of each patient's cumulative exposure to each bacterial taxon. Bacterial taxa of each patient present at a frequency >1% were evaluated for association with the outcome of relapse or progression of disease within the first year after allo-HSCT using linear discriminant analysis of effect size (LEfSe), a common approach in microbiota studies (Segata et al., Genome Biology, 2011). Among the taxons most significantly associated with freedom from relapse were members of the human oral flora including Streptococcus anginosus. After stratifying the patients by median abundance, we found that those with higher abundance of this bacterium had less relapse after transplantation (Left figure, p = 0.0014). We also identified bacteria associated with increased risk of relapse, such as Enterococcus faecium (Right figure, p = 0.0103). We evaluated these bacteria as biomarkers in multivariate Cox models adjusted for three factors that were associated with relapse in this cohort: Refined Disease Risk Index (RDRI, Armand et al., Blood 2014), conditioning intensity, and graft source (cord blood vs. adult donor). Streptococcus anginosus predicted relapse in a multivariate model adjusted for all three factors (HR 0.39, 95% CI 0.16-0.96, p = 0.041). Enterococcus faecium predicted relapse in a model adjusted for RDRI and conditioning intensity but failed to do so in a model additionally adjusted for graft source. In this analysis there was no formal adjustment for multiple comparisons; these data are now being validated in an additional cohort of patients whose samples are being sequenced. Finally, although we have previously reported that low bacterial diversity is associated with decreased overall survival after allo-HSCT (Taur et al., Blood 2014), we did not find an association between bacterial diversity and relapse as assessed by reciprocal Simpson diversity index (p > 0.1). Thus, the results of this retrospective analysis have identified an association between relapse after allo-HSCT and the abundance of two bacteria in the intestinal flora. These might serve as potential novel diagnostics or therapeutic targets to prevent relapse and improve overall survival after allo-HSCT. Figure 1. Figure 1.

Abstract Introduction: As the number of long-term survivors following HSCT is increasing, the long-term risks and associated morbidity has become important component of survivorship program. The known risk factors for developing cancer include use of chemotherapy agents, radiation exposure, immune dysfunction, previous malignancy in addition to other factors and as HSCT process involves all these factors, this single centre retrospective analysis was undertaken to evaluate the risk of developing SSC in the patients receiving transplant. Methods: From February 1982 to February 2016, 2231 patients received 2495 transplants (median age: 46yr., range: 14-76 yr.; M: 1586, F: 909) for haematological malignancies (Leuk: 744, lymphoma:767, myeloma:848, solid tumours/other:136). Donor was allogeneic (n=744) or autologous (n=1751) and conditioning was with (n=614) or without TBI (n=1881). Donor was sibling (n=375), matched unrelated (n=355), haploidentical relative (n=3) or umbilical cord blood (n=11). Source of stem cell was marrow (n=367), PBSC (n=2086), both (n=31) or cord blood (n=11). GVH prophylaxis included Campath or ATG in 369 cases. Of all the patients 1985 received single transplant, 231 had two, 13 had 3 and 2 had 4 HSCT procedures. Data was analysed as of 15/04/2016 using competing risk model with death as the competing event. Comparison of incidence to general population was performed by computing standardized incidence rates (SIR). Patients with second haematological malignancy were not included in this analysis. Results: Median follow-up was 5.3 years (range: 0-32 years). Patient follow-up was more than 10 years in 467 cases (19%), between 5 to 10 years in 430 (17%), 2 to 5 years in 607 (24%) and less than 1 year in 997 cases (40%). 36% patients were followed-up for more than 5 years. Second solid cancers developed in 116 patients with the incidence of 1% at 5yr (95% CI: 0.5-2.6), 3% at 10 yr (95% CI: 1.6-5.3), 6% at 15yr (95%CI: 3.6-8.8) and 10% (95% CI: 5.9-15.5) at 20 years. Median time to develop SSC from date of HSCT was 11 yr (range: 0.4-28.1 yr). Primary site for SSC included skin (n=37), breast (n=22), GI (n=15), GU (n=16), H&N (n=10), lung (n=6), CNS (n=4), Endocrine (n=4) & HPB (n=2). There was no difference with type of transplant i.e. auto or allograft. Autograft and allograft groups were analysed separately. In univariate analysis, allograft group showed higher cumulative incidence of SSC with use of PBSC (p<0.0001), campath/ATG (p=0.0002), donor other than sibling (P=0.0004), RIC (p<0.0001), non-TBI conditioning (p=0.007), older age at transplant (0.008), development of agvhd or cgvhd (p=0.023) and transplant year after 2000 (p=0.01). In multivariate analysis age above 50 (RR: 1.8, 95%CI: 1.2-1.8, p=0.046) and RIC (RR: 4.4, 95% CI: 1.2-8.3, p=0.03) were independently associated with higher risk of SSC. In autograft group, there were no independent risk factors in univariate or multivariate analysis. As compared to general population incidence was higher for all cancers (SIR=7.4) and also cancers at every primary site. Risk was highest for breast (SIR=14.3), Head/neck (SIR=25.6), brain (SIR=17.4) and colon (SIR=6.2). Overall survival is significantly shorter in patients who develop SSC (median: 12 yr vs. not reached, p<0.0001). The median time to develop SSC from the date of HSCT has significantly shortened over last three decades (years 1982-1990: 21yr, 1991-2000: 11.1 yr, 2001-2010: 6.34 yr, 2011-2016: 2.2 yr; p=0.0001) Conclusion: This single centre analysis confirms that the risk of developing SSC increases with advancing age, use of RIC allograft, longer follow-up and leads to inferior survival. Since the year 2000, SSC are developing early after transplant and it needs to be evaluated if this is a trend seen at other centers and if so, is it related to increasing use of RIC, increasing number of elderly patients, severity of immune-suppression or higher incidence of GVHD.

Abstract Introduction: Ruxolitinib was the first JAK 1/2 inhibitor (JAKi) approved for myelofibrosis (MF), with several other JAKi in development. Ruxolitinib was approved on the basis of reducing splenomegaly and improving constitutional symptoms, but its effect on subsequent allogeneic stem cell transplantation (SCT) is not well understood. Retrospective studies to date have reported mixed outcomes after SCT for MF patients with previous exposure to JAKi. In this multicenter retrospective study, we report on outcomes of patients with MF treated with SCT at our institutions. Methods: We analyzed outcomes for 184 consecutive patients at three institutions who underwent SCT for primary or secondary MF. Primary outcomes included overall survival (OS), progression free survival (PFS), and graft-versus-host-disease (GVHD)-free and relapse-free survival (GRFS), all measured from the time of SCT. Cox proportional hazard regressions were fit to estimate the association between the use of JAK 1/2 inhibitors prior to SCT and OS, PFS, and GRFS, adjusting for donor type and DIPSS-plus status. p<0.05 was considered statistically significant. Results: 72 patients received a JAKi prior to SCT, while 112 did not. Patients in these two groups were well-matched with respect to age, sex, DIPSS plus score, conditioning, and donor type (Table 1). Median follow-up was 31.2 months (range: 0.8-146.3 months). In univariate analysis, there was no difference in OS (JAKi: 4-yr OS 56.7% [95% CI 40.9-69.8%] vs. no JAKi: 43.6% [95% CI 32.9-53.9%], p=0.49), PFS (JAKi: 4 yr PFS 54.1% [95% CI 40.8-65.7%] vs. no JAKi: 43.9% [95% CI 33.4-53.9%], p=0.77), or GRFS (JAKi: 8-month GRFS 56.6% [95% CI 44.1-67.4%] vs. no JAKi: 50.4% [95% CI 40.4-59.5%], p=0.62) in the overall population; there was similarly no difference when comparing only intermediate-risk or only high-risk patients. In multivariate analysis, there was no difference in these outcomes for patients based on previous JAKi exposure when accounting for DIPSS plus score and donor type (related vs unrelated). Rates of acute GVHD were similar between the two groups (JAKi: 53.5% vs. no JAKi: 55.0%, p=0.88), including grade 3 or 4 acute GVHD (JAKi: 16.9% vs no JAKi: 19.8%, p=0.70). Conclusions: Our data suggest that there is no statistically significant difference in OS, PFS, GRFS, or rates of acute GVHD after SCT for MF patients based on previous JAKi treatment. This was true overall and after adjusting for DIPSS plus risk score or donor type. Given the retrospective design of our study, we were not able to assess prior response to JAKi or splenomegaly at SCT, which may influence outcomes. Given mixed results in the literature to date, we eagerly await the results of ongoing phase 2 trials of JAKi prior to SCT for MF. Disclosures Ho: Jazz Pharmaceuticals: Consultancy.

Abstract Introduction: Multiple myeloma patients over the age of 65 represent the majority of myeloma population. The main goal was to evaluate treatment outcomes in terms of overall survival for elderly patients based on initial choice of anti-myeloma drugs, and to find potential factors affecting survival. Patients and Methods: This is a retrospective registry based analysis from the Registry of monoclonal gammopathies of the Czech Myeloma Group. Patients with multiple myeloma diagnosed between 2007-2016 over the age of 65 with symptomatic myeloma were included in the analysis. Basic demographic data and disease characteristics were obtained. The Kaplan-Meier estimates were completed by the Greenwood confidence interval. The log-rank test was used to estimate the statistical significance of the difference between the curves. The Cox proportional hazards model was performed to explore the univariate significance of risk factors. Results: Data from 1410 MM patients were obtained. Gender [HR 1.316 (1.124-1.541), p=0.001], age [above 75 vs. 66-75, HR 1.437 (1.221-1.692), p< 0.001], creatinine levels [at cutoff 152 µmol/L, HR 1.613 (1.365-1.905), p< 0.001] and ECOG performance status [0-1 vs. 2-4, 1.869 (1.594-2.191), p< 0.001] were found to significantly affect overall survival. Moreover these risk factors have cumulative effect on overall survival of the patients. Overall survival of patients regardless to above mentioned risk factors treated with upfront bortezomib (N = 880) was median OS 40.4 months (CI: 36.1-44.7), patients treated with upfront thalidomide (N = 370) had median OS 48.1 months (CI: 41.0-55.2), for lenalidomide (N = 64) median overall survival was 53.2 months (CI: 44.6-61.8) and for combination of bortezomib and thalidomide (N = 46) 32.2 months (CI: 26.6-37.8). When any of these risk factors was present the OS in each group shortened. In the group of patients with no risk factors (N = 255) the median OS for bortezomib (N = 126) was not reached, for thalidomide (N = 96) the median OS was 66.3 months (CI: 43.1-89.6), for lenalidomide (N = 17) 71.1 months (CI: 44.8-97.4) and for combination of bortezomib and thalidomide (N=8) was not reached. In the group of patients with 1 risk factor (N = 514) the median OS for bortezomib (N = 303) was 46.1 months (CI: 36.2-56.1), for thalidomide (N = 141) 56.2 months (CI: 47.5-64.9), for lenalidomide (N = 29) 49.0 months (CI: 9.7-88.2) and for combination of bortezomib and thalidomide (N=20) was not reached. In the group of patients with 2 risk factors (N = 420) the median OS for bortezomib (N = 288) was 34.0 months (CI: 24.7-43.4), for thalidomide (N = 87) 31.9 months (CI: 22.8-40.9), for lenalidomide (N = 14) 33.2 months (CI: 0.0-67.6) and for combination of bortezomib and thalidomide (N=20) 29.4 months (CI: 7.6-51.1). In the group of patients with 3-4 risk factors (N = 221) the median OS for bortezomib (N = 163) was 19.2 months (CI: 14.9-23.5), for thalidomide (N = 46) 18.9 months (CI: 13.0-24.7), for lenalidomide (N = 4) 6.1 months (CI: 0.0-63.0) and for combination of bortezomib and thalidomide (N=3) 14.3 months (CI:-). Conclusion: The overall survival of patients above the age of 65 shows promising results with the use of novel agents. The treatment outcomes seem to be generally affected by overall condition, age and gender of the patient rather than treatment modality used upfront. Figure. Figure.
