Abstract
BACKGROUND The goal of our study was to find predictors for the development of secondary myelodysplastic syndrome or acute myelogenous leukemia (s-MDS/AML) in patients with relapsed or refractory lymphoma who received high-dose chemotherapy and autologous stem cell transplantation (ASCT). STUDY DESIGN AND METHODS We conducted a retrospective review of 295 patients with relapsed or refractory lymphoma who had undergone their first stem cell collection and ASCT. Patient, disease, and treatment characteristics were collected. The primary goal of this study was to analyze the association between the number of apheresis days needed to collect the requisite stem cell dose in addition to the previously described factors such as age, sex, number and type of prior chemotherapeutic regimens, disease type and status, and the risk of developing s-MDS/AML. RESULTS Twenty-two patients of 295 were diagnosed with s-MDS/AML after a median follow-up of 62 months. Multivariate analysis using a classification and regression tree showed that the incidence of s-MDS/AML was lowest in patients who were not more than 55 years old at transplantation and in whom the target cell dose was collected in fewer than two apheresis sessions (5-year cumulative incidence, 1%), whereas incidence was highest in patients who were more than 55 years old at transplantation and who received a transplant more than 21 months after their initial lymphoma diagnosis (5-year cumulative incidence, 20%). CONCLUSION Our study defines a subset of relapsed or refractory lymphoma patients who should be closely monitored for development of s-MDS/AML after high-dose chemotherapy and ASCT.

Abstract
138 Background: More than 60% of cancer patients are older adults. Such patients undergo age and cancer therapy related changes. Older adults also have geriatric risk factors for falls such as frailty, cognitive impairment (mild cognitive impairment [MCI] and dementia), and malnutrition-including vitamin D deficiency. Objective: To assess the prevalence of vitamin D insuffiency and risk factors for falls in older cancer patients. Retrospective cohort study. Methods: Patients underwent prospective data collection and retrospective analysis. Patients underwent a comprehensive geriatric assessments, including cognitive, functional, nutritional, physical, and comorbidity assessment. Vitamin D was assayed. Bone densitometry was performed. Analysis: Descriptive statistics, and multivariable logistic regression. Results: We enrolled 318 patients and 305 patients with complete data were included for final analysis. Patients were undergoing active cancer care. Patients had gastrointestinal, urologic, breast, lung and gynecologic cancers. The mean age was 78.4 ± 6.9 years. Low bone mass and osteoporosis were very common (80%) in this cohort. Twenty-six percent had one or more falls in the preceding six months. Dementia and mild cognitive impairment were seen in 33% and 37% of patients, and 53% presented frailty. In 256 patients, 48.8% (n = 125) had Vitamin D insufficiency ( < 30 ng/ml). In univariate analysis, co-morbidity (p = 0.05), frailty (p < 0.01), and cognitive impairment (0 = 0.02) were significantly associated with falls, while in multivariate analysis, frailty remained significantly associated with falls (OR = 3.51, 95%CI = 1.88, 6.52). Conclusions: Older cancer patients have a high prevalence of falls, osteoporosis and vitamin D insufficiency, raising the possibility of injurious falls (fractures). Frailty was found to be the most prominent risk factor for falls in this cohort. Greater awareness and targeted interventions such as vitamin D replacement, physical therapy, nutrition interventions, and therapy for low bone mass/osteoporosis will be effective preventing injurious falls.

Abstract
BACKGROUND BK polyomavirus (BKPyV) infections are known indicators of immune suppression in hematopoietic stem cell transplant (HSCT) recipients; they can lead to hemorrhagic cystitis, ureteral stenosis, renal dysfunction, and prolonged hospital stays. In this study, we determined transplant-associated variables and immune parameters that can predict for the risk of BKPyV viruria. We hypothesized that BKPyV infection is a marker of poor immune recovery. METHODS We analyzed all engrafted patients undergoing first allogeneic HSCT at MD Anderson Cancer Center in Houston between January 2004 and December 2012. We evaluated their immune parameters and their transplant-associated factors. BKPyV positivity was defined as BKPyV detection in urine by polymerase chain reaction testing. Cox proportional hazards model, as well as competing risk analysis method using subdistribution hazard models with death as competing risk, were applied to assess risk of BKPyV viruria. RESULTS We identified a total of 2477 patients with a median age of 52 years. BKPyV viruria was manifest in 25% (n=629) of the patients. The median time from transplantation to BKPyV viruria development was 42 days among the patients who had BKPyV viruria. On multivariate analysis, tumor type, acute GVHD, chronic GVHD, myeloablative conditioning regimen, cord blood as the graft source, CD3+ , CD4+ , CD8+ , CD56+ , NK counts, and low platelet count were shown to be significantly associated with BKPyV infection. These finding were further confirmed when models incorporating the competing risk of death yielded similar findings. CONCLUSION In this study, we report significant associations between BKPyV reactivation following allogeneic HSCT and suppressed immune variables. In addition, this study provides valuable information on the immune status of HSCT recipients as a predictor of BKPyV infections that may in turn help us formulate plans for more effective prevention and treatment of this infection.

Fludarabine with pharmacokinetically guided IV busulfan is superior to fixed-dose delivery in pretransplant conditioning of AML/MDS patients. Bone Marrow Transplant 2016; 52:580-587. [PMID: 27991894 PMCID: PMC5382042 DOI: 10.1038/bmt.2016.322] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2016] [Revised: 09/28/2016] [Accepted: 09/30/2016] [Indexed: 11/25/2022]
Abstract
We hypothesized that IV Busulfan (Bu) dosing could be safely intensified through pharmacokinetic (PK-) dose guidance to minimize the inter-patient variability in systemic exposure (SE) associated with body-sized dosing, and this should improve outcome of AML/MDS patients undergoing allogeneic stem cell transplantation (allo-HSCT). To test this hypothesis, we treated 218 patients (median age 50.7 years, male/female 50/50%) with fludarabine (Flu) 40 mg/m2 once daily ×4, each dose followed by IV Bu, randomized to 130 mg/m2 (N=107) or PK-guided to average daily SE, AUC of 6,000 µM-min (N=111), stratified for remission-status, and allo-grafting from HLA-matched donors. Toxicity and graft vs. host disease (GvHD) rates in the groups were similar; the risk of relapse or treatment-related mortality remained higher in the fixed-dose group throughout the 80-month observation period. Further, PK-guidance yielded safer disease-control, leading to improved overall and progression-free survival, most prominently in MDS-patients and in AML-patients not in remission at allo-HSCT. We conclude that AML/MDS patients receiving pretransplant conditioning treatment with our 4-day regimen may benefit significantly from PK-guided Bu-dosing. This could be considered an alternative to fixed dose delivery since it provides the benefit of precise dose delivery to a predetermined SE without increasing risk(s) of serious toxicity and/or GvHD.

Abstract
The gain/amplification of the CKS1B gene on chromosome 1q21 region is associated with a poor outcome in patients with multiple myeloma (MM). However, there are limited data on the outcome of patients with CKS1B amplification after a single high-dose chemotherapy and autologous hematopoietic stem cell transplantation (auto-HCT). We retrospectively evaluated the outcome of patients with CKS1B amplification who received an auto-HCT between June 2012 and July 2014 at our institution. We identified 58 patients with MM and CKS1B gene amplification detected by fluorescent in situ hybridization (FISH). We compared their outcomes with a propensity score-matched control group of 58 patients without CKS1B amplification who were treated at approximately the same time. The primary objective was to compare the progression-free (PFS) and overall survival (OS) between the CKS1B and the control groups. Stratified log-rank test with the matched pairs as strata and double robust estimation under the Cox model were used to assess the effect of CKS1B gene amplification on PFS or OS in the matched cohort. Patients in the CKS1B and control groups were well matched for age, gender, disease status, year of auto-HCT, response to pretransplantation therapy, and baseline hemoglobin level. In both groups, 57% patients were in first remission and 43% had relapsed disease at auto-HCT. Twenty-seven (47%) patients with CKS1B amplification had concurrent monosomy 13 or 13q deletion; 6 (10%) by conventional cytogenetics only, 16 (28%) by FISH only, and 5 (9%) by both. Median follow-up after auto-HCT was 25.4 months. The median PFS of the CKS1B and the control groups were 15.0 months and 33.0 months (P = .002), respectively. The median OS have not been reached yet. The 2-year OS rates in the CKS1B and the control groups were 62% and 91% (P = .02), respectively. In conclusion, Patients with CKS1B amplification are more likely to have additional high-risk cytogenetic abnormalities and a shorter PFS and OS after an auto-HCT.

Abstract
Haploidentical transplantation performed with post-transplantation cyclophosphamide (PTCy)-based graft-versus-host disease (GVHD) prophylaxis has been associated with favorable outcomes for patients with acute myeloid leukemia and lymphomas. However, it remains unclear if such approach is effective for patients with acute lymphoblastic leukemia (ALL). We analyzed outcomes of 109 consecutively treated ALL patients 18 years of age and older at 5 institutions. The median age was 32 years and the median follow-up for survivors was 13 months. Thirty-two patients were in first complete remission (CR1), while the rest were beyond CR1. Neutrophil engraftment occurred in 95% of the patients. The cumulative incidences of grades II to IV and III and IV acute GVHD at day 100 after transplantation were 32% and 11%, respectively, whereas chronic GVHD, nonrelapse mortality, relapse rate, and disease-free survival (DFS) at 1 year after transplantation were 32%, 21%, 27%, and 51%, respectively. Patients in CR1 had 52% DFS at 3 years. These results suggest that haploidentical transplants performed with PTCy-based GVHD prophylaxis provide a very suitable alternative to HLA-matched transplantations for patients with ALL.

Abstract
We investigated the long-term safety and disease control data obtained with i.v. busulfan (Bu) combined with clofarabine (Clo) in patients with acute lymphoblastic leukemia (ALL) undergoing allogeneic hematopoietic stem cell transplantation (HSCT). A total of 107 patients, median age 38 years (range, 19 to 64 years) received a matched sibling donor (n = 52) or matched unrelated donor (n = 55) transplant for ALL in first complete remission (n = 62), second complete remission (n = 28), or more advanced disease (n = 17). Nearly one-half of the patients had a high-risk cytogenetic profile as defined by the presence of t(9;22) (n = 34), t(4;11) (n = 4), or complex cytogenetics (n = 7). Clo 40 mg/m2 was given once daily, with each dose followed by pharmacokinetically dosed Bu infused over 3 hours daily for 4 days, followed by hematopoietic cell infusion after 2 days of rest. The Bu dose was based on the drug clearance as determined by a test Bu dose of 32 mg/m2. The target daily area under the curve was 5500 µmol/min for patients aged <60 years and 4000 µmol/min for patients aged >59 years. With a median follow-up of 3.3 years among surviving patients (range, 1 to 5.8 years), the 2-year progression-free survival (PFS) for patients undergoing HSCT in first complete remission (CR1), second complete remission (CR2), or more advanced disease was 62%, 34%, and 35%, respectively. The regimen was well tolerated, with nonrelapse mortality (NRM) of 10% at 100 days and 31% at 2 years post-HSCT. The incidence of grade II-IV and III-IV acute graft-versus-host disease (GVHD) was 35% and 10%, respectively; 18% patients developed extensive chronic GVHD. The 2-year overall survival (OS) for patients undergoing HSCT in CR1, CR2, or more advanced disease was 70%, 57%, and 35%, respectively. Among 11 patients aged >59 years treated with reduced-dose Bu in CR1 (n = 7) or CR2 (n = 4), 4 remain alive and disease-free, with a median follow-up of 2.6 years (range, 2 to 4.7 years). Only the presence of minimal residual disease at the time of transplantation was associated with significantly worse PFS and OS in multivariate analysis. Our data indicate that the Clo-Bu combination provides effective disease control while maintaining a favorable safety profile. OS and NRM rates compare favorably with those for traditional myeloablative total body irradiation-based conditioning regimens.

Abstract
BACKGROUND The introduction of novel prognostic factors such as minimal residual disease (MRD) and genomic profiling has led to the reevaluation of the role of cytogenetics and other conventional factors in risk stratification for acute lymphoblastic leukemia (ALL). METHODS This study assessed the impact of baseline cytogenetics on the outcomes of 428 adult patients with Philadelphia chromosome-negative ALL who were receiving frontline chemotherapy. Three hundred thirty patients (77%) were treated with hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone-based regimens, and 98 (23%) were treated with the augmented Berlin-Frankfurt-Munster regimen. RESULTS The median age was 40 years (range, 13-86 years). One hundred eighty-six patients (43%) had diploid cytogenetics, 32 (7%) had complex cytogenetics (defined as ≥ 5 chromosomal abnormalities), 27 (6%) had low hypodiploidy/near-triploidy (Ho-Tr), 24 (6%) had high hyperdiploidy, and 24 (6%) had a mixed-lineage leukemia (MLL) rearrangement. Patients with an MLL rearrangement, Ho-Tr, or a complex karyotype had significantly worse relapse-free survival (RFS) and overall survival (OS) than the diploid group. According to a multivariate analysis including all the baseline characteristics and MRD status, Ho-Tr and a complex karyotype were independent predictive factors for worse RFS and OS. Furthermore, survival among all cytogenetic groups was similar, regardless of the treatment received. CONCLUSIONS A complex karyotype and Ho-Tr are adverse prognostic factors for adults with ALL independently of the MRD status. These findings suggest that pretreatment cytogenetics remain a valuable prognostic tool in this population. Cancer 2017;123:459-467. © 2016 American Cancer Society.

Abstract
BACKGROUND Although lenalidomide maintenance therapy has demonstrated improved outcomes after autologous hematopoietic stem cell transplantation (auto-HCT) for patients with multiple myeloma (MM), the impact of the duration of this therapy is not clearly known. METHODS This study retrospectively analyzed all MM patients who were placed on maintenance lenalidomide after auto-HCT between January 2007 and December 2013. Progression-free survival (PFS) and overall survival (OS) were analyzed in multivariate Cox proportional hazards regression models that included the duration of maintenance as a time-dependent covariate. RESULTS Of the 464 patients identified, 46% initiated therapy early (<4 months after auto-HCT). The median PFS and OS were 38 and 78 months, respectively. Improvements in PFS (hazard ratio [HR], 0.13; 95% confidence interval [CI], 0.04-0.38; P < .001) and OS (HR, 0.09; 95% CI, 0.03-0.26; P < .001) were seen for those on maintenance for >2 years versus those on maintenance for ≤2 years. For those on maintenance for >3 versus those on maintenance for ≤3 years, this trend continued with improvements seen in PFS (HR, 0.02; 95% CI, 0.00-0.44; P = .012) and OS (HR, 0.05; 95% CI, 0.00-0.83; P = .037). The incidence of second primary malignancies (SPMs) in the entire cohort was 3%. No differences were seen in survival between early and late initiators of maintenance lenalidomide. CONCLUSIONS A longer duration of maintenance therapy was associated with longer survival. The incidence of SPMs was low, and they were not associated with the duration of maintenance. The timing of the initiation of maintenance had no effect on survival. Cancer 2016;122:3831-3837. © 2016 American Cancer Society.

Abstract
PR1, an HLA-A2-restricted peptide derived from both proteinase 3 and neutrophil elastase, is recognized on myeloid leukemia cells by cytotoxic T lymphocytes (CTL) that preferentially kill leukemia and contribute to cytogenetic remission. To evaluate safety, immunogenicity and clinical activity of PR1 vaccination, a phase I/II trial was conducted. Sixty-six HLA-A2+ patients with acute myeloid leukemia (AML: 42), chronic myeloid leukemia (CML: 13) or myelodysplastic syndrome (MDS: 11) received three to six PR1 peptide vaccinations, administered subcutaneously every 3 weeks at dose levels of 0.25, 0.5 or 1.0 mg. Patients were randomized to the 3 dose levels after establishing the safety of the highest dose level. Primary endpoints were safety and immune response, assessed by doubling of PR1/HLA-A2 tetramer-specific CTL, and the secondary endpoint was clinical response. Immune responses were noted in 35 of 66 (53%) patients. Of the 53 evaluable patients with active disease, 12 (24%) had objective clinical responses (complete: 8, partial: 1 and hematological improvement: 3). PR1-specific immune response was seen in 9 of 25 clinical responders vs. 3 of 28 clinical non-responders (p=0.03). In conclusion, PR1 peptide vaccine induces specific immunity that correlates with clinical responses, including molecular remission, in AML, CML and MDS patients.

BACKGROUND Minimal residual disease (MRD) assessment predicts survival for patients with newly diagnosed acute lymphoblastic leukemia (ALL). Its significance in relapsed/refractory ALL is less clear. METHODS This study identified 78 patients with relapsed/refractory B-cell ALL who achieved a morphologic response with inotuzumab ozogamicin (n = 41), blinatumomab (n = 11), or mini-hyperfractionated cyclophosphamide, vincristine, and doxorubicin plus inotuzumab (n = 26) during either salvage 1 (S1; n = 46) or salvage 2 (S2; n = 32) and had undergone an MRD assessment by multiparameter flow cytometry at the time of remission. RESULTS MRD negativity was achieved in 41 patients overall (53%). The MRD negativity rate was 57% in S1 and 47% in S2. Among patients in S1, achieving MRD negativity was associated with longer event-free survival (EFS; median, 18 vs 7 months; 2-year EFS rate, 46% vs 17%; P = .06) and overall survival (OS; median, 27 vs 9 months; 2-year OS, 52% vs 36%; P = .15). EFS and OS were similar in S2, regardless of the MRD response. Among MRD-negative patients who underwent allogeneic stem cell transplantation (SCT), EFS and OS were superior for those who underwent SCT in S1 rather than S2 (P = .003 and P = .04, respectively). Patients in S1 who achieved MRD negativity and subsequently underwent SCT had the best outcomes with a 2-year OS rate of 65%. CONCLUSIONS Patients with relapsed/refractory ALL who achieve MRD negativity in S1 can have long-term survival. Patients in S2 generally have poor outcomes, regardless of their MRD status.

Abstract
Adoptive immunotherapy infusing T cells with engineered specificity for CD19 expressed on B- cell malignancies is generating enthusiasm to extend this approach to other hematological malignancies, such as acute myelogenous leukemia (AML). CD123, or interleukin 3 receptor alpha, is overexpressed on most AML and some lymphoid malignancies, such as acute lymphocytic leukemia (ALL), and has been an effective target for T cells expressing chimeric antigen receptors (CARs). The prototypical CAR encodes a VH and VL from one monoclonal antibody (mAb), coupled to a transmembrane domain and one or more cytoplasmic signaling domains. Previous studies showed that treatment of an experimental AML model with CD123-specific CAR T cells was therapeutic, but at the cost of impaired myelopoiesis, highlighting the need for systems to define the antigen threshold for CAR recognition. Here, we show that CARs can be engineered using VH and VL chains derived from different CD123-specific mAbs to generate a panel of CAR+ T cells. While all CARs exhibited specificity to CD123, one VH and VL combination had reduced lysis of normal hematopoietic stem cells. This CAR’s in vivo anti-tumor activity was similar whether signaling occurred via chimeric CD28 or CD137, prolonging survival in both AML and ALL models. Co-expression of inducible caspase 9 eliminated CAR+ T cells. These data help support the use of CD123-specific CARs for treatment of CD123+ hematologic malignancies.

Abstract
Our aim was to improve outcome prediction after allogeneic hematopoietic stem cell transplantation in acute myeloid leukemia by combining cytogenetic and molecular data at diagnosis with minimal residual disease assessment by multicolor flow-cytometry at transplantation. Patients with acute myeloid leukemia in first complete remission in whom minimal residual disease was assessed at transplantation were included and categorized according to the European LeukemiaNet classification. The primary outcome was 1-year relapse incidence after transplantation. Of 152 patients eligible, 48 had minimal residual disease at the time of their transplant. Minimal residual disease-positive patients were older, required more therapy to achieve first remission, were more likely to have incomplete recovery of blood counts and had more adverse risk features by cytogenetics. Relapse incidence at 1 year was higher in patients with minimal residual disease (32.6% versus 14.4%, P=0.002). Leukemia-free survival (43.6% versus 64%, P=0.007) and overall survival (48.8% versus 66.9%, P=0.008) rates were also inferior in patients with minimal residual disease. In multivariable analysis, minimal residual disease status at transplantation independently predicted 1-year relapse incidence, identifying a subgroup of intermediate-risk patients, according to the European LeukemiaNet classification, with a particularly poor outcome. Assessment of minimal residual disease at transplantation in combination with cytogenetic and molecular findings provides powerful independent prognostic information in acute myeloid leukemia, lending support to the incorporation of minimal residual disease detection to refine risk stratification and develop a more individualized approach during hematopoietic stem cell transplantation.

Abstract
The Bcr-Abl tyrosine kinase regulates several Bcl-2 family proteins that confer resistance to apoptosis in chronic myeloid leukemia (CML) cells. Given p53's ability to modulate the expression and activity of Bcl-2 family members, we hypothesized that targeting Bcr-Abl, Bcl-2, and p53 concomitantly could have therapeutic benefits in blast crisis (BC) CML and in quiescent CML CD34+ cells that are insensitive to tyrosine kinase inhibitors (TKI). We examined the effects of the MDM2 inhibitor nutlin3a and its combination with the dual Bcl-2 and Bcl-xL inhibitor ABT-737, and the Bcr-Abl inhibitor nilotinib on BC CML patient samples. We found that in quiescent CD34+ progenitors, p53 expression is significantly lower, and MDM2 is higher, compared to their proliferating counterparts. Treatment with nutlin3a induced apoptosis in bulk and CD34+CD38- cells, and in both proliferating and quiescent CD34+ progenitor CML cells. Nutlin3a synergized with ABT-737 and nilotinib, in part by inducing pro-apoptotic, and suppressing anti-apoptotic, Bcl-2 proteins. Nilotinib inhibited the expression of Bcl-xL and Mcl-1 in BC CML cells. These results demonstrate that p53 activation by MDM2 blockade can sensitize BC CML cells, including quiescent CD34+ cells, to Bcl-2 inhibitor- and TKI-induced apoptosis. This novel strategy could be useful in the therapy of BC CML.

Abstract
BACKGROUND The role of day 14 (D14) bone marrow (BM) assessment in detecting increased blasts in patients undergoing induction for acute lymphoblastic leukemia (ALL) is not well defined. METHODS This study evaluated 389 adolescent and adult patients with previously untreated Philadelphia chromosome-negative ALL who received frontline induction chemotherapy and for whom a D14 BM assessment was performed. RESULTS A D14 BM blast proportion < 10% (including blast-free aplastic BM) was observed in 319 patients (82%), 10% to 29% was observed in 31 patients (8%), and ≥30% was observed in 39 patients (10%). The composite complete remission (CR)/complete remission with inadequate platelet recovery (CRp) rates for these groups were 99.7%, 87%, and 79%, respectively. The median event-free survival (EFS) was 49, 33, and 9 months, respectively (P < .001). The median overall survival (OS) was 88, 37, and 21 months, respectively (P < .001). The D14 BM blast group was the only factor predictive for the achievement of CR/CRp (P < .001). According to a multivariate analysis, the D14 BM blast group was independently prognostic for both EFS (hazard ratio [HR], 1.44; 95% confidence interval [CI], 1.12-1.85; P = .004) and OS (HR, 1.45; 95% CI, 1.14-1.85; P = .003). However, when minimal residual disease (MRD) assessment at the time of CR was added to the model, the D14 BM blast group was no longer prognostic for EFS or OS. CONCLUSIONS An assessment of residual D14 BM blasts in patients with ALL is highly predictive of the achievement of CR with induction chemotherapy and of EFS and OS. However, the D14 BM blast assessment is less prognostic of long-term outcomes when an MRD assessment is also available. Cancer 2016;122:3812-3820. © 2016 American Cancer Society.

Abstract
BACKGROUND T cells expressing antigen-specific chimeric antigen receptors (CARs) improve outcomes for CD19-expressing B cell malignancies. We evaluated a human application of T cells that were genetically modified using the Sleeping Beauty (SB) transposon/transposase system to express a CD19-specific CAR. METHODS T cells were genetically modified using DNA plasmids from the SB platform to stably express a second-generation CD19-specific CAR and selectively propagated ex vivo with activating and propagating cells (AaPCs) and cytokines. Twenty-six patients with advanced non-Hodgkin lymphoma and acute lymphoblastic leukemia safely underwent hematopoietic stem cell transplantation (HSCT) and infusion of CAR T cells as adjuvant therapy in the autologous (n = 7) or allogeneic settings (n = 19). RESULTS SB-mediated genetic transposition and stimulation resulted in 2,200- to 2,500-fold ex vivo expansion of genetically modified T cells, with 84% CAR expression, and without integration hotspots. Following autologous HSCT, the 30-month progression-free and overall survivals were 83% and 100%, respectively. After allogeneic HSCT, the respective 12-month rates were 53% and 63%. No acute or late toxicities and no exacerbation of graft-versus-host disease were observed. Despite a low antigen burden and unsupportive recipient cytokine environment, CAR T cells persisted for an average of 201 days for autologous recipients and 51 days for allogeneic recipients. CONCLUSIONS CD19-specific CAR T cells generated with SB and AaPC platforms were safe, and may provide additional cancer control as planned infusions after HSCT. These results support further clinical development of this nonviral gene therapy approach. TRIAL REGISTRATION Autologous, NCT00968760; allogeneic, NCT01497184; long-term follow-up, NCT01492036.

Abstract
BACKGROUND High-dose, post-transplantation cyclophosphamide (PTCy) to prevent graft-versus-host disease (GVHD) has improved outcomes in haploidentical (HAPLO) stem cell transplantation (SCT). However, it remains unclear whether this strategy is effective in SCT from 1-antigen human leukocyte antigen (HLA)-mismatched unrelated donors (9/10 MUD) and how the outcomes of these patients compare with those of haploidentical transplantation recipients. METHODS A parallel, 2-arm, nonrandomized phase 2 clinical trial was conducted of melphalan-based reduced-intensity conditioning with PTCy, tacrolimus, and mycophenolate mofetil to prevent GVHD in patients with high-risk hematologic malignancies who underwent HAPLO (n = 60) or 9/10 MUD (n = 46) SCT. RESULTS The 1-year overall and progression-free survival rates were 70% and 60%, respectively, in the HAPLO arm and 60% and 47%, respectively, in the 9/10 MUD arm. The day +100 cumulative incidence of grade II to IV acute GVHD and grade III to IV acute GVHD was 28% and 3%, respectively, in the HAPLO arm and 33% and 13%, respectively, in the 9/10 MUD arm. The 2-year cumulative incidence of chronic GVHD was 24% in the HAPLO arm and 19% in the 9/10 MUD arm. The 1-year cumulative incidence of nonrelapse mortality was 21% in the HAPLO arm and 31% in the 9/10 MUD arm, and the 1-year relapse rate was 19% in the HAPLO arm and 25% in the 9/10 MUD arm. CONCLUSIONS Although this was a nonrandomized study and could not serve as a direct comparison between the 2 groups, the authors conclude that PTCy-based GVHD prophylaxis is effective for both HAPLO and 9/10 MUD SCTs. Prospective randomized trials will be required to compare the efficacies of alternative donor options for patients lacking HLA-matched donors.

Abstract
Pretransplant conditioning regimens critically determine outcomes in the setting of allogeneic stem cell transplantation (allo-SCT). The use of nucleoside analogs such as fludarabine (Flu) in combination with i.v. busulfan (Bu) has been shown to be highly effective as a pretransplant conditioning regimen in acute myeloid leukemia (AML), chronic myeloid leukemia (CML), and myelodysplastic syndrome (MDS). Because leukemia relapse remains the leading cause of death after allo-SCT, we studied whether clofarabine (Clo), a nucleoside analog with potent antileukemia activity, can be used to complement Flu. In a preliminary report, we previously showed the safety and efficacy of Clo ± Flu with i.v. Bu in 51 patients with high-risk AML, CML, and MDS. The study has now been completed, and we present long-term follow-up data on the entire 70-patient population, which included 49 (70%), 8 (11%), and 13 (19%) patients with AML, MDS, and CML, respectively. Thirteen patients (19%) were in complete remission, and 41 patients (59%) received matched unrelated donor grafts. Engraftment was achieved in all patients. Sixty-three patients (90%) achieved complete remission. There were no deaths reported at day +30, and the 100-day nonrelapse mortality rate was 4% (n = 3). Thirty-one percent of patients (n = 22) developed grades II to IV acute graft-versus-host disease, and the median overall survival and progression-free survival times were 2.4 years and .9 years, respectively. Our results confirm the safety and overall and progression-free survival advantage of the arms with higher Clo doses and lower Flu doses, which was most prominent in the AML/MDS group.

Abstract
The adverse prognosis of internal tandem duplication in the FMS-like tyrosine kinase 3 gene(s) (FLT3-ITD) in patients with acute myelogenous leukemia (AML) may depend on allelic burden. We compared postremission treatment with chemotherapy and hematopoietic stem cell transplantation (HSCT) in 169 FLT3-ITDmut intermediate cytogenetic risk AML patients with allelic ratio evaluable at diagnosis who achieved first complete remission (CR1) with induction therapy. To minimize selection bias, the analysis was limited to patients who remained in CR1 for at least 4 months (median time to HSCT) after achieving CR1, and propensity score matching was implemented. Sensitivity analysis including patients who remained in CR1 for at least 3 months was applied as well. HSCT in CR1 was associated with longer relapse-free survival (RFS) and overall survival (OS), with 3-year estimated rates of 18% and 24%, respectively (P < .001), for patients receiving chemotherapy and 46% and 54%, respectively (P < .001), for those undergoing HSCT. Multivariate regression models showed that HSCT remained statistically significant with improved RFS and OS independent of FLT3-ITD allelic ratio and NPM1 status. Irrespective of postremission therapy, relapse remains the main reason for treatment failure, with a 3-year incidence of 68% in chemotherapy recipients versus 41% in HSCT recipients. Allogeneic HSCT improved disease outcomes compared with chemotherapy after propensity score matching was applied. The improvement observed for RFS (hazard ratio [HR], 0.55; P = .09) and OS (HR, 0.58; P = .10) with HSCT as postremission therapy in patients who remained in CR1 for at least 4 months did not reach statistical significance; however, the sensitivity analyses including patients who remained in CR1 for at least 3 months showed significant improvement in both RFS (HR, 0.31; P = .002) and OS (HR, 0.27; P = .02) after propensity score matching. Our results indicate that HSCT in CR1 for AML FLT3-ITDmut patients is associated with longer RFS and OS. Innovative transplantation strategies to improve relapse incidence are urgently needed.

Abstract
Novel approaches to pre-transplant conditioning are needed to improve treatment of advanced T-cell malignancies. We investigated the synergism of fludarabine (Flu), clofarabine (Clo), busulfan (Bu), and romidepsin (Rom) in T-cell lines and patient-derived cell samples. [Flu+Clo+Bu+Rom] had combination indexes of 0.4-0.5 at ∼50% cytotoxicity in PEER and SUPT1 cells, suggesting synergism. Drug exposure resulted in histone modifications, DNA-damage response (DDR), increased reactive oxygen species (ROS), decreased glutathione (GSH) and mitochondrial membrane (MM) potential, and apoptosis. Similar activation of DDR and apoptosis was observed in patient samples. The PI3K-AKT-mTOR, NFκB, Raf-MEK-ERK, JAK-STAT and Wnt/β-catenin pro-survival pathways were inhibited by the 4-drug combination. The SAPK/JNK stress pathway was activated. A novel finding was the down-regulation of the drug transporter MRP1. We propose the following mechanisms of synergism: Flu, Clo and Rom induce histone modifications and chromatin remodeling, exposing DNA to Bu alkylation; the increased production of ROS, due to drug-mediated stress response and decreased GSH, damages the MM causing leakage of pro-apoptotic factors; down-regulation of MRP1 increases intracellular Bu concentration and exacerbates the DDR; and inhibition of multiple survival pathways. Our results provide the basis for a clinical trial to evaluate [Flu+Clo+Bu+Rom] as part of conditioning regimen for refractory T-cell malignancy patients undergoing stem cell transplantation.

Abstract
Nephropathy due to BK virus (BKV) infection is an evolving challenge in patients undergoing hematopoietic stem cell transplantation (HSCT). We hypothesized that BKV infection was a marker of kidney function decline and a poor prognostic factor in HSCT recipients who experience this complication. In this retrospective study, we analyzed all patients who underwent their first allogeneic HSCT at our institution between 2004 and 2012. We evaluated the incidence of persistent kidney function decline, which was defined as a confirmed reduction in estimated glomerular filtration rate of at least 25% from baseline using the Chronic Kidney Disease Epidemiology equation. Cox proportional hazard regression was used to model the cause-specific hazard of kidney function decline, and the Fine-Gray method was used to account for the competing risks of death. Among 2477 recipients of a first allogeneic HSCT, BK viruria was detected in 25% (n = 629) and kidney function decline in 944 (38.1%). On multivariate analysis, after adjusting for age, sex, acute graft-versus-host disease (GVHD), chronic GVHD, preparative conditioning regimen, and graft source, BK viruria remained a significant risk factor for kidney function decline (p < 0.001). In addition, patients with BKV infection and kidney function decline experienced worse overall survival. After allogeneic HSCT, BKV infection was strongly and independently associated with subsequent kidney function decline and worse patient survival after HSCT.

Abstract
Allogeneic stem cell transplantation is an effective treatment for high-risk myeloid malignancies, but relapse remains the major post-transplantation cause of treatment failure. Alloreactive natural killer (NK) cells mediate a potent antileukemic effect and may also enhance engraftment and reduce graft-versus-host disease (GVHD). Haploidentical transplantations provide a setting in which NK cell alloreactivity can be manipulated, but they are associated with high rates of GVHD. We performed a phase I study infusing escalating doses of NK cells from an HLA haploidentical-related donor-selected for alloreactivity when possible-as a component of the preparative regimen for allotransplantation from a separate HLA-identical donor. The goal of infusing third-party alloreactive NK cells was to augment the antileukemic effect of the transplantation without worsening GVHD and, thus, improve the overall outcome of hematopoietic transplantation. Twenty-one patients with high-risk acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or chronic myelogenous leukemia refractory or beyond first remission received a preparative regimen with busulfan and fludarabine followed by infusion of apheresis-derived, antibody-selected, and IL-2-activated NK cells. Doses were initially based on total nucleated cell (TNC) content and later based on CD56(+) cells to reduce variability. CD56(+) content ranged from .02 to 8.32 × 10(6)/kg. IL-2, .5 × 10(6) units/m(2) subcutaneously was administered daily for 5 days in the final cohort (n = 10). CD3(+) cells in the NK cell product were required to be < 10(5)/kg. Median relapse-free, overall, and GVHD-free/relapse-free survival for all patients enrolled was 102, 233, and 89 days, respectively. Five patients are alive, 5 patients died of transplantation-related causes, and 11 patients died of relapse. Despite the small sample size, survival was highly associated with CD56(+) cells delivered (P = .022) and development of ≥ grade 3 GVHD (P = .006). There were nonsignificant trends toward higher survival rates in those receiving NK cells from KIR ligand-mismatched donors and KIR-B haplotype donors. There was no association with disease type, remission at time of transplantation, or KIR content. GVHD was not associated with TNC, CD56(+), or CD3(+) cells infused in the NK cell product or the stem cell product. This trial demonstrates a lack of major toxicity attributable to third-party NK cell infusions delivered in combination with an HLA-compatible allogeneic transplantation. The infusion of haploidentical alloreactive NK cells was well tolerated and did not interfere with engraftment or increase the rate of GVHD after allogeneic hematopoietic transplantation. Durable complete remissions occurred in 5 patients at high risk for disease recurrence. This approach is being further developed in a phase I/II trial with ex vivo-expanded NK cells to increase the NK cell dose with the objective of reducing relapse and improving the outcome of allogeneic hematopoietic transplantation for AML/MDS.

Abstract
Forty patients (median age, 31 years; range, 20 to 63) with Hodgkin lymphoma underwent an allogeneic stem cell transplant with the gemcitabine-fludarabine-melphalan reduced-intensity conditioning regimen. Thirty-one patients (77%) had undergone a prior autologous stem cell transplant, with a median time to progression after transplant of 6 months (range, 1 to 68). Disease status at transplant was complete remission/complete remission, undetermined (n = 23; 57%), partial remission (n = 14; 35%), and other (n = 3; 8%). Twenty-six patients (65%) received brentuximab vedotin before allotransplant. The overall complete response rate before allotransplant was 65% in brentuximab-treated patients versus 42% in brentuximab-naive patients (P = .15). At the latest follow-up (October 2015) 31 patients were alive. The median follow-up was 41 months (range, 5 to 87). Transplant-related mortality rate at 3 years was 17%. Pulmonary, skin toxicities, and nausea were seen in 13 (33%), 11 (28%), and 37 (93%) patients, respectively. At 3 years, estimates for overall and progression-free survival were 75% (95% CI, 57% to 86%) and 54% (95% CI, 36% to 70%). Overall incidence for disease progression was 28% (95% CI, 16% to 50%). We believe the gemcitabine-fludarabine-melphalan regimen allows moderate dose intensification with acceptable morbidity and mortality. The inclusion of gemcitabine affected nausea, pulmonary, and likely skin toxicity. Exposure to brentuximab vedotin allowed more patients to reach allogeneic stem cell transplantation in complete remission. With over 50% of patients progression-free at 3 years, allogeneic stem cell transplantation with reduced-intensity conditioning remains an effective and relevant treatment option for Hodgkin lymphoma in the brentuximab vedotin era.

Abstract
Significant progress has been made over the past decade in haploidentical transplantation, with the development of novel methods to control intense alloreactive reactions generated in the major HLA-mismatched setting. Application of post-transplantation cyclophosphamide has gained worldwide acceptance as an effective and low-cost way to perform this type of transplantation, with outcomes now similar to those from HLA-matched unrelated donors. These advances have resulted in improved treatment-related mortality, whereas disease relapse has emerged as the most common cause of treatment failure. In addition, improvements in immunologic reconstitution after transplantation are much needed, not only in haploidentical transplantation but in all forms of stem cell transplantation. This symposium has focused on some of the most promising methods to control alloreactivity in this form of transplantation and application of cellular therapy to prevent disease relapse after transplantation, as well as understanding immunologic reconstitution and foreseeable approaches to improve immune recovery after transplantation.

Abstract
DNA alkylators busulfan (B) and melphalan (M) act synergistically with gemcitabine (G) against lymphoma cells. To further improve the cytotoxicity, we combined them with the histone deacetylase inhibitor panobinostat (P) and proteasome inhibitor bortezomib (V). Lymphoma cell lines U937 and J45.01, and patient-derived cell samples were exposed to these drugs and the effects on cell proliferation and apoptosis were quantified. The combination BMGPV was found to exert strong synergistic cytotoxicity. Drug exposure to these cells activated the ATM pathway and modified histones at the epigenetic level. Cell death was triggered by the production of reactive oxygen species (ROS), permeabilization of the mitochondrial membrane, upregulation of proapoptotic factors, and activation of caspases. Downregulation of anti-apoptotic proteins c-MYC, MCL-1, and BCL-2 and inhibition of the prosurvival PI3K-AKT-mTOR pathway, culminated in apoptosis. The results of this study support a clinical trial using BMGPV as a possible pre-transplant conditioning regimen for relapsed/refractory lymphoma patients.

Abstract
Hematopoietic stem cell transplantation (HSCT) is an effective treatment for patients with refractory lymphomas. Nucleoside analogs (NAs) and DNA alkylating agents are efficacious in treating hematologic malignancies. To design an efficacious and more economical pretransplant regimen for lymphoma patients, we analyzed the cytotoxicity of cladribine (Clad), gemcitabine (Gem), busulfan (Bu), and suberoylanilide hydroxamic acid (SAHA) in lymphoma cell lines. J45.01 and U937 lymphoma cell lines were exposed to drugs, alone or in combination, for 48 hours and analyzed with the MTT and annexin V assays, Western blotting, and flow cytometry. On the basis of the IC5-10 values of the drugs, the Clad+Gem+Bu combination inhibited the proliferation of both cell lines to ∼55%-60%. Addition of SAHA to this combination decreased proliferation further to ∼30%. Exposure to the Clad+Gem+Bu+SAHA combination activated the DNA damage response and ATM-CHK2 pathway; modified histones; decreased mitochondrial membrane potential, which caused leakage of apoptosis-inducing factors; and activated apoptosis. Pretreatment of cells with the pan-caspase inhibitor Z-VAD-FMK blocked the phosphorylation of histone 2AX and cleavage of PARP-1 and caspases. The Clad+Gem+Bu+SAHA combination provides synergistic cytotoxicity in lymphoma cell lines. Our results may be a basis for using this combination as a pretransplant conditioning regimen in a clinical trial for lymphoma patients undergoing hematopoietic stem cell transplantation, replacing the more expensive nucleoside analog clofarabine.

Abstract
Post-transplantation cyclophosphamide (PTCy) is an effective strategy to prevent graft-versus-host disease (GVHD) after haploidentical haematopoietic cell transplantation (HCT). We determined the efficacy of PTCy-based GVHD prophylaxis in human leucocyte antigen (HLA)-mismatched unrelated donor (MMUD) HCT. We analysed 113 adult patients with high-risk haematological malignancies who underwent one-antigen MMUD transplantation between 2009 and 2013. Of these, 41 patients received PTCy, tacrolimus and mycophenolate mofetil (MMF) for GVHD prophylaxis; 72 patients received conventional prophylaxis with anti-thymocyte globulin, tacrolimus and methotrexate. Graft source was primarily bone marrow (83% PTCy vs. 63% conventional group). Incidence of grade II-IV (37% vs. 36%, P = 0·8) and grade III-IV (17% vs. 12%, P = 0·5) acute GVHD was similar at day 100. However, the incidence of grade II-IV acute GVHD by day 30 was significantly lower in the PTCy group (0% vs. 15%, P = 0·01). Median time to neutrophil (18 days vs. 12 days, P < 0·001) and platelet (25·5 days vs. 18 days, P = 0·05) engraftment was prolonged in PTCy group. Rates of graft failure, chronic GVHD, 2-year non-relapse mortality, relapse, progression-free survival or overall survival were similar. Our results demonstrate that PTCy, tacrolimus and MMF for GVHD prophylaxis is safe and produced similar results as conventional prophylaxis in patients with one antigen HLA-MMUD HCT.

Abstract
In major ABO-mismatched allogeneic hematopoietic stem cell transplantation (HSCT) persistence of antidonor isohemagglutinins leads to pure red cell aplasia (PRCA). To investigate severe pancytopenia noted in a previous study of PRCA, we analyzed all major ABO-mismatched HSCT between January 2003 and December 2012. Of 83 PRCA patients, 13 (16%) had severe pancytopenia. Severe pancytopenia was defined as an absolute neutrophil count (ANC) < 1.5 K/μL or requiring granulocyte colony-stimulating factor, platelets < 50 K/μL or transfusion dependent, and PRCA with RBC transfusion dependence at post-transplant day 90. In 6 patients (46%) severe pancytopenia resolved after PRCA resolution. Two patients (15%) received a second transplant because of persistent pancytopenia/secondary graft failure, 1 (8%) died from secondary graft failure despite a stem cell boost, 1 (8%) did not recover his platelet counts despite RBC/ANC recovery, and 3 patients (23%) died from disease relapse. We found that severe pancytopenia is frequently associated with PRCA in 16% of major ABO-incompatible HSCT with a higher incidence in males and pancytopenia resolved with resolution of PRCA in 46% of patients.

Abstract
Mismatch of human leukocyte antigens (HLA) adversely impacts the outcome of patients after allogeneic hematopoietic stem-cell transplantation (alloHSCT). This translates into the clinical requirement to timely identify suitable HLA-matched donors which in turn curtails the chances of recipients, especially those from a racial minority, to successfully undergo alloHSCT. We thus sought to broaden the existing pool of registered unrelated donors based on analysis that eliminating the expression of the HLA-A increases the chance for finding a donor matched at HLA-B, -C, and -DRB1 regardless of a patient’s race. Elimination of HLA-A expression in HSC was achieved using artificial zinc finger nucleases designed to target HLA-A alleles. Significantly, these engineered HSCs maintain their ability to engraft and reconstitute hematopoiesis in immunocompromised mice. This introduced loss of HLA-A expression decreases the need to recruit large number of donors to match with potential recipients and has particular importance for patients whose HLA repertoire is under-represented in the current donor pool. Furthermore, the genetic engineering of stem cells provides a translational approach to HLA-match a limited number of third-party donors with a wide number of recipients.

Abstract
The safety and efficacy of siltuximab (CNTO 328) was tested in combination with lenalidomide, bortezomib and dexamethasone (RVD) in patients with newly-diagnosed, previously untreated symptomatic multiple myeloma. Fourteen patients were enrolled in the study, eleven of whom qualified to receive therapy. A majority of patients (81.8%) completed the minimal number or more of the four required cycles, while two patients completed only three cycles. The maximum tolerated dose (MTD) of siltuximab with RVD was dose level −1 (siltuximab: 8.3 mg/kg; bortezomib: 1.3 mg/m2; lenalidomide: 25 mg; dexamethasone: 20 mg). Serious adverse events were grade 3 pneumonia and grade 4 thrombocytopenia, and no deaths occurred during the study or with follow-up (median follow-up 28.1 months). An overall response rate, after 3–4 cycles of therapy, of 90.9% (95% confidence interval (CI): 58.7%, 99.8%) (9.1% complete response (95% CI: 0.2%, 41.3%), 45.5% very good partial response (95% CI: 16.7%, 76.6%) and 36.4% partial response (95% CI: 10.9%, 69.2%)) was seen. Two patients withdrew consent, and nine patients (81.8%) opted for autologous stem cell transplantation.

Abstract
32 Background: Older adults, 65 years of age and older, with hematologic cancers may be at higher risk for cognitive impairment. It is postulated that the etiology of cognitive impairment in cancer may a combination of age-related and chemotherapy related cognitive impairment. Methods: We conducted a retrospective cohort analysis, of older adult patients 65 years and older evaluated at the Program for Healthy Aging at MD Anderson from January 1, 2013 through March 31, 2015. Cognitive assessment was evaluated through personal interview, and the Montreal cognitive assessment, functional assessment utilizing ADLs and IADLs. Screening for depression was conducted with the PHQ-9. Patients were interviewed regarding risk factors for dementia including depression, concussions, alcohol abuse, and family history of dementia. Level of education was assessed. Patients were euthymic. Cognitive impairment was defined as an abnormal MOCA without functional impairment, dementia was defined as an abnormal MOCA with functional impairment. Imaging and assessment for reversible factors of memory loss was conducted. SAS 9.4 (SAS Institute INC, Cary, NC) was used for data analysis. Results: The majority of these 62 patients had received chemotherapy for more than 2 years. Cognitive impairment and/or dementia were identified in 50 (80.6%) patients. Types of dementia included Alzheimer’s disease (n = 4, 8%), vascular dementia (n = 5, 10 %), and mixed dementia (n = 15, 30%).Mild cognitive impairment was evidenced in 14 cases (28%) The majority of cases of dementia with known stage were early stage dementia (n = 13, 72.2%), moderate stage dementia (n = 3, 16.7%), and advanced or severe dementia (n = 2, 11.1%). Brain imaging was performed identifying white matter microischemic changes, cerebrovascular accidents and brain atrophy in some cases. No significant thyroid abnormalities, B12 deficiency or other reversible causes were identified. Conclusions: Cognitive impairment and dementia are prevalent in older patients with hematologic malignancies. Identification and management of this condition may prevent delirium and hospital complications during stem cell transplantation.

The effect of donor characteristics on survival after unrelated donor transplantation for hematologic malignancy. Blood 2016; 127:260-7.

Abstract
There are >24 million registered adult donors, and the numbers of unrelated donor transplantations are increasing. The optimal strategy for prioritizing among comparably HLA-matched potential donors has not been established. Therefore, the objective of the current analyses was to study the association between donor characteristics (age, sex, parity, cytomegalovirus serostatus, HLA match, and blood group ABO match) and survival after transplantation for hematologic malignancy. The association of donor characteristics with transplantation outcomes was examined using either logistic or Cox regression models, adjusting for patient disease and transplantation characteristics associated with outcomes in 2 independent datasets: 1988 to 2006 (N = 6349; training cohort) and 2007 to 2011 (N = 4690; validation cohort). All donor-recipient pairs had allele-level HLA typing at HLA-A, -B, -C, and -DRB1, which is the current standard for selecting donors. Adjusting for patient disease and transplantation characteristics, survival was better after transplantation of grafts from young donors (aged 18-32 years) who were HLA matched to recipients (P < .001). These findings were validated for transplantations that occurred between 2007 and 2011. For every 10-year increment in donor age, there is a 5.5% increase in the hazard ratio for overall mortality. Increasing HLA disparity was also associated with worsening survival. Donor age and donor-recipient HLA match are important when selecting adult unrelated donors. Other donor characteristics such as sex, parity, and cytomegalovirus serostatus were not associated with survival. The effect of ABO matching on survival is modest and must be studied further before definitive recommendations can be offered.
