Abstract Abstract 892 The myeloablative, reduced toxicity regimen, IV Busulfan (Bu) and fludarabine (Flu), is effective conditioning for allogeneic stem cell transplantation for treatment of patients with AML and MDS. We performed a prospective randomized study to optimize the antileukemic cytoreduction of this regimen, testing the hypothesis that pharmacokinetically (PK-) guided IV Bu-dosing to an average daily AUC of 6,000 μMol-min yields improved leukemia-free survival compared with a fixed IV Bu dose of 130 mg/m2, which gives a median AUC of approximately 5000 μMol-min. The study was approved by the M.D. Anderson Cancer Center IRB and all patients provided informed consent. 139 patients were in a first or second complete remission (CR), 86 were not in remission, including patients with marrow remission but with incomplete hematologic recovery (CRi) or with active disease. Median age was 50 years (range 13–65). 51% received a transplant from a related donor and 49% had unrelated donors. 28% patients received bone marrow and 72% PBPC grafts. Disease characteristics are summarized in the following table. Median follow-up of surviving patients was 25 months (2–66). The patients receiving PK guided busulfan dosing had significantly better progression free survival at 3 years than the fixed dose group, 56% (45–66%) vs. 42% (32–52%) P=0.03, as well as lower cumulative incidence of progression 23% (16–34%) vs. 35% (27–46%) p=0.03. Overall survival at 3 years for the two groups was 57% (46–68%) vs 47% (36–57%) p=0.2. The greatest effect was seen in patients not in remission at the time of transplant. The cumulative incidence of disease progression for the PK Guided and Fixed dose groups was 20% and 25% in patients transplanted in remission (P=0.5), and 29% and 50% for patients transplanted not in remission (P=0.03). Major outcomes are summarized in the following table. There was no significant difference in toxicity pattern, incidence of acute GVHD or treatment related mortality between the PK-guided/adjusted and fixed- dose groups. In multivariate analysis, poor risk cytogenetics and flt3 mutation was associated with inferior PFS. In conclusion, administration of higher dose intravenous busulfan using pharmacokinetic dose guidance targeting an AUC of 6000 μMol-min combined with fludarabine improved progression free survival in patients undergoing allogeneic stem cell transplantation for treatment of AML and MDS, without increasing the risks for serious toxicity and treatment-related mortality.

Abstract The prognosis for patients with mantle cell lymphoma (MCL) treated with conventional chemotherapy remains poor. Dose escalation and stem cell transplantation has been increasingly employed in an attempt to improve the outcome in these patients. However, due to the advanced age of many patients with MCL, high dose therapy and allogeneic stem cell transplantation is particularly hazardous. Reduced intensity allogeneic transplantation (RIT) may reduce the toxicity of allogeneic stem cell transplantation, facilitate allogeneic engraftment and graft versus lymphoma reactions. However, the results reported to date with this treatment modality have been based on small numbers of patients and provide conflicting results. We have therefore analysed the outcome of a large cohort of patients with MCL reported to the EBMT registry who have undergone RIT. A total of 144 patients (123 male) with a histological diagnosis of MCL were reported by 81 centres. The median age at transplant was 49 years (range 28–68 years) and the median time from diagnosis to transplant was 25 months (range 0.25–13.2 years). The patients had received a median of 2 (range 1–5) lines of prior chemotherapy and 60 (42%) had undergone a prior high dose procedure. At the time of RIT 100 patients had chemosensitive disease, 22 chemoresistant disease and 22 had untested relapse. Patients underwent conditioning with reduced intensity regimens prior to transplantation with allogeneic peripheral blood stem cells (122), bone marrow (20) or both (1). Fully matched sibling donors were used in 109 cases, matched unrelated donors in 21 and 9 patients received mismatched stem cells. 123 of 126 patients assessable for engraftment demonstrated sustained engraftment. With a median follow up of 9 months 84 patients remain alive and 60 have died (15 from progressive disease and 45 from non-relapse mortality). The transplant related mortality (TRM) was 12% at 100 days but by Kaplan-Mier analysis the TRM was 35% at 1 year and 50% at two years. In univariate analysis there was a non-significant trend to a higher TRM in patients with chemoresistant disease (p=0.067) and those with a prior transplant (p=0.062). Patient age and the number of lines of prior therapy had no impact on TRM. At two years following transplant 57% of patients had evidence of disease relapse or progression which was significantly worse in those with chemoresistant disease prior to transplant (p=0.02). The overall survival (OS) at 1 year and 2 years was 55% and 31% respectively and was worse for patients with chemoresistant disease. The progression free survival (PFS) at 1 and 2 year was 43% and 26% respectively. Only disease status at transplantation predicted for a worse PFS. Acute GVHD (grade II-IV) developed in 52 patients and chronic GVHD in 23 patients. Although the early transplant related toxicity is low there remains a significant TRM following RIT for MCL and consequently a low progression free survival. Patients with chemoresistant disease have a particularly poor outcome.

Abstract Abstract 1180 Poster Board I-202 Benjamin Esterni, Didier Blaise Background: Allogeneic stem cell transplantation (ALLO) is the only curative therapy for many hematological malignancies. For many of these diseases, the median age at diagnosis is around the sixth decade of life, precluding myeloablative ALLO (MAC-ALLO). RIC-ALLO is less toxic and it has been performed in elderly pts, mainly affected by acute leukemia. Finally, comorbidities index seem to predict treatment related mortality (TRM) and overall survival (OS). Patients and methods: From 2001 and 2008, 67 pts older than 60 years (median age 63 y, range 60-70) received RIC-ALLO. Diseases were: acute myeloid leukemia 45%, multiple myeloma 18%, chronic lymphocytic leukemia 12%, non-Hodgkin lymphoma 10%, myelodysplasia 6%, plasmacellular leukemia 3%, others 6%. Disease status at RIC-ALLO was: complete remission 54%, partial remission 16%, and active disease 30%. RIC consisted of fludarabine-based with thymoglobulin 64%, or low-dose TBI-based 36%. Donors were: HLAid sibling 73%, matched unrelated 21%, and cord blood 6%. Previous autologous transplant was performed in 59% of pts. The median number of CD34+ and CD3+ cells infused was 5 (range 1-9.4) and 296 (range 84-704), respectively. Karnofski score was 60-80% in 25% and 90-100% in 75%; HCT-CI was 0 in 33%, 1-2 in 33%, and more than 3 in 34%; PAM score was 8-16 in 9%, 17-33 in 65%, 24-30 in 22%, and more than 31 in 3%; EBMT score was 2 in 22%, 3 in 36%, 4 in 28%, more than 5 in 12%. Results: The median follow-up was 22 months. The 2-y OS and PFS were 66.8% (IC95 [55.5-80.4]) and 52.4% (IC95 [39.5-69.5]), respectively. Grade II-IV acute graft versus host disease (aGVHD) and chronic GVHD (cGVHD) incidence were 49% and 43%, respectively. Early infections were fever of unknown origin in 42% of pts, bacterial infection in 6 cases, pneumonia in 8, and viral infections in 14. The early infection-related mortality was null. Late infections were bacterial in 3 cases, pneumonia in 1, viral infections in 6, and candidemia in 1. Seven pts died from late infective complications. Overall, the cause of death was toxicities in 18 pts and disease progression in 6 pts. The 100-d and 1-y TRM were 6.35% (IC95 [0.278-12.4]) and 24.2% (IC95 [12.9-35.4]), respectively. In univariate analysis, HCT-CI, EBMT score, and PAM score did not influence TRM or OS. Furthermore, age (60-65 vs 66-70) was not related to TRM. Conclusions: The aim of this retrospective study was to verify if TRM was excessively high in elderly pts, affected from several haematological diseases and receiving ALLO from different donors and after different RIC. A secondary objective was to evaluate if several comorbidities index could predict TRM and OS. This heterogeneity should be regarded as a more realistic view of general population. TRM was acceptable and not different when compared to younger pts as reported in literature. Furthermore, neither comorbidities index nor age help segregate a group of pts with different TRM. Disclosures: No relevant conflicts of interest to declare.

PURPOSE: Conventional allogeneic stem-cell transplantation (SCT) after a prior failed autograft is associated with a transplant-related mortality rate of 50% to 80%. The aim of the current study was to evaluate the safety and efficacy of sibling, HLA-matched, nonmyeloablative allogeneic SCT with donor lymphocyte infusion (DLI) in patients with lymphoid malignancy after failure of autologous SCT. PATIENTS AND METHODS: A total of 38 patients with refractory, progressive, or relapsed disease after autologous SCT were entered onto this study. The conditioning regimen consisted of the humanized monoclonal antibody CAMPATH-1H, fludarabine, and melphalan. Fifteen of 35 assessable patients received DLI after SCT. RESULTS: Sustained neutrophil engraftment was achieved in 37 recipients, and platelet engraftment was achieved in 35 patients. The estimated transplant-related mortality was 7.9% at day 100 and 20% at 14 months, the median duration of follow-up. Eight patients experienced grade I/II acute graft-versus-host disease (GVHD) after transplantation, but no grade III/IV GVHD was observed in this setting. However, grade III/IV GVHD occurred in seven patients who received DLI. The actuarial overall survival at 14 months was 53%, with a progression-free survival of 50%. DLI produced a further response in three of 15 recipients. CONCLUSION: Nonmyeloablative allogeneic SCT after CAMPATH-1H–containing conditioning is a relatively safe option compared with conventional allogeneic transplantation for patients who have failed previous autologous SCT. The low incidence of early GVHD enabled the subsequent administration of DLI to improve further clinical responses in this poor-risk group of lymphoma and myeloma patients.

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.
