Abstract Abstract 1969 Background: High-risk MM remains a very difficult clinical challenge despite advances in therapy for the majority of patients who have benefited from the use of high-dose therapies and novel agents. Recognizing that MM from the outset represents a genomically highly complex malignancy with even further accelerated acquisition of mutations with every further relapse, we have tried to develop multi-agent combinations employing drugs with efficacy in other high-grade tumors such as large cell lymphomas and incorporated novel agents as well. Patients and Methods: Eighty-four patients with AHRMM were given PACMED comprising cisplatin (15-25mg/m2 CI × 3d), cytarabine (1.0-1.5g/m2/d × 3), cyclophosphamide (1.0-1.5g/m2/d CI × 3), mesna (1.0-1.5g/m2/d CI × 3), etoposide (0.3-0.5g/m2/d × 3) and DEX (40-100mg/d × 3); additional agents included bortezomib (1.0-1.6mg/m2 on days 1 + 4), thalidomide (100-200mg/d × 4d) or lenalidomide (25-100mg/d × 4) and rapamycin (3mg d 1, 1mg d 2–4) with or without HPC boost. Statistical methods included Cox regression modeling for OS and EFS, along with Kaplan-Meier methodology for survival and cumulative incidence plots. Survival comparisons were made using the logrank test. Results: Baseline characteristics included age >=65 in 18%, B2M >=3.5mg/L in 68% and >5.5mg/L in 38%, CRP >=8mg/L in 60%, LDH >=ULN in 57%, and cytogenetic abnormalities (CA) in 62%. Gene expression profiling (GEP)-defined high-risk (70 genes, R70; 80 genes, R80) was present in 80% and 71%; PR (Proliferation), MF and MS subtypes were present in 44%, 27% and 14%. Prior transplants (Tx) had been given to 96%, including 40% who received 2Tx, 25% with 3Tx and 14% with >3Tx. PR was achieved by 29%, including 14% n-CR and 8% CR. 1-year estimates of OS and EFS were low at 13% and 8%, and median durations were 5 and 3 months. Increased age and high LDH were the only baseline characteristics adversely affecting both OS and EFS. The 29 patients with neither of these risk factors experienced 1-yr OS/EFS rates of 31%/17%; the corresponding values with 1 risk factor (n=47) were 5%/4% and with both risk factors (n=8) 0%/0%. Conclusion: Single cycle PACMED provides only transient tumor control in this heavily pretreated population with 80% displaying GEP-defined high-risk and 62% CA, as a manifestation of end-stage MM. We are currently evaluating repeated cycles of PACMED earlier in the disease course in high-risk MM, in the context of a Super-BEAM transplant regimen.

Abstract Abstract 4800 Background: Despite availability of novel agents, many MM patients still relapse and require salvage interventions. In the Arkansas program, we have attempted to procure initially sufficient hematopoietic precursor cells, for use in high-dose therapy salvage regimens once phase I-II trials have been exhausted. We are reporting on the efficacy in terms of response rate, EFS and OS of ARMM patients receiving S-BEAM. Patients and Methods: S-BEAM comprised standard BEAM (carmustine 300 mg/m2 on day 1, etoposide 200 mg/m2 days 1–4, cytarabine 400 mg/m2 days 1–4, melphalan 140 mg/m2 on day 5) with the addition of cisplatin (10-12.5mg/m2/d CI × 5d), bortezomib (1.3-1.5mg/m2 on days 1 + 4), thalidomide (100-200mg/d for 5 days) or lenalidomide (25-100mg/d for 5 days), DEX (40-100mg/d for 5 days) plus rapamycin (3mg d1, 1mg d2-5). Statistical methods included Cox regression modeling using significance level 0.05 and Kaplan-Meier methodology for all figures. Comparisons within figures were made using the log-rank test. Results: The characteristics of 147 patients treated included prior transplant (Tx) in 67% (2Tx, 29%; =>3Tx, 11%), and prior exposure and resistance in virtually all patients (92%) to bortezomib, thalidomide, lenalidomide applied in VTD, VRD or with chemotherapy VTD-PACE. Pre-S-BEAM high-risk features included low albumin (<3.5g/dL; 66%) high B2M (>=3.5mg/L; 32%), high LDH (>=ULN; 44%), and presence of cytogenetic abnormalities (CA) in 70%. Clinical outcomes included at least PR in 62% including 48% with n-CR and 29% with CR. Two-year estimates of EFS and OS were 29% and 33%; TRM within 60 days was 3%. At 4 years, 23% remain alive and 15% event-free. Independently significant variables affecting both OS and EFS adversely included, in a model without GEP, high B2M (>5.5mg/L), high LDH (>=ULN), low hemoglobin (<10g/dL) and CA, whereas achieving PR improved survival. Based on R2-driven independent adverse variables, B2M, LDH and CA were linked to poor outcomes, with 1-year estimates of OS/EFS of 83%/69% with 0, 63%/52% with 1, 25%/9% with 2, and 13%/0% with more than 2 high-risk parameters. Gene expression profiling (GEP)-defined high-risk was present in 55% (70 genes, R70) and in 47% (80 genes, R80); delTP53 was noted in 21% and Proliferation Index (PI) score >=10 in 42%. When GEP data were included in a subset of 103 patients, high-risk designation, high LDH and age >=65 were identified on the basis of highest R2 values (49% for OS, 41% for EFS). Among 28 patients lacking any of these 3 features, 1-year OS/EFS was 83%/67%, with 1 variable (n=36) 53%/38%, with 2 (n=31) 22%/6% and with 3 (n=8) 0%/0% (both P<0.001). Applying a cut-off of 2 adverse variables, the 60 patients with 2 or fewer enjoyed 2-year OS of 49% and EFS of 48%, as opposed to 7% and 4%, respectively, among the remaining 36 patients with more than 2 risk features. Conclusion: S-BEAM provides effective salvage therapy in ARMM with 60-day TRM of 3% and prognostic factor-dependent survival expectation. We are currently evaluating S-BEAM earlier in the disease course, with PAC-MED as induction prior to and as consolidation after S-BEAM in high-risk myeloma. Overall survival by number of non-GEP risk factors (B2M, LDH, CA), selected based on maximum R2 value (38% for OS, 33% for EFS) Overall survival by number of risk factors (age, LDH, GEP high-risk), selected based on maximum R2 values (49% for OS, 41% for EFS) Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction It is postulated that the improvement in the overall treatment outcome in adult Ph-negative ALL came from the implementation of more aggressive pediatric-like protocols and higher portion of allogeneic HSCT. Here we report the results of the adult (15-55 yy) Ph-negative ALL protocol based on the opposite approaches: less intensive but non-interruptive treatment with low numbers of allo-HSCT. The study is registered on the ClinicalTrials.gov public site; NCT01193933. Patients and Methods The ALL-2009 is based on: (1) the replacement of prednisolone (Pdn) 60 mg/m2 with dexamethazone (Dexa) 10 mg/m2 if blast cells are >25% in b/m after prephase (7d); (2) de-intensified but non-interruptive 5 months induction/consolidation treatment (5 wks prd/dexa with 3 instead of 4 dauno/vncr pulses, 4 weeks of 6MP with 5 L-asp, 2 instead of 4 ARA-C blocks, 1 instead of 2 Cph injections during induction; induction-like 3 consolidations for 3wks, 2wks, 4wks-continuously without intervals), followed by (3) 2 late (at 6 mo) intensifications- with 1 day HD MTX and with 1 d HD ARA-C, both with L-asp and 3 ds dexa and (4) 2-yrs continuous 6MP/MTX maintenance with doses modification according to myelosuppression with monthly 3-days dexa/vncr/L-asp pulses (∑ L-asp = 590.000 IU/m2). The protocol was identical for all risk groups. Allo-HSCT was indicated only for extremely high-risk BCP-ALL (t(4;11),L>100). No central MRD monitoring was performed. Since Apr 2009 till June 2015 20 centers had recruited 168 BCP-Ph-negative ALL pts with a median age 28 years (15-54), 84f/84 m. Full cytogenetics was available in 67,3% (n=113), 43,4% of them (n=49) had normal karyotype (NK), 10% (n=9%) had no mitosis, 47,6% (n=54) - different abnormalities (hypoploid-1, hyperploid-12, t(11q23)/MLL-8, del11q23-2, t(1;19)-2, t(12;21)-1;others-28). 26,7% of pts (n=45) were in the standard risk (SR) group (WBC <30, EGIL BII-III, LDH < 2N; no late CR; t(4;11)-negative), 56,5% (n=95) - in the high risk (HR) group (WBC >30; EGIL BI, LDH > 2N; late CR; t(4;11)-positive), 28 patients (n=16,8%) were not qualified by the risk. The analysis was performed in June 2015. 158 pts were available for analysis. Results CR rate in 158 available for analysis pts was 87,7% (n=139), induction death occurred in 9,1% (n=14), resistance was registered in 3,2% (n=5). The majority of CR pts (87,8%) achieved it after prephase (12,2%, n=17) and the 1st phase of induction (75,6%, n=105). Late responders constituted 12,2% (n=17). Allogeneic BMT was performed only in 9 of 144 patients who survived induction (6,2%). Totally 31 pts (22,3%) had relapsed. At 60 mo OS for the whole group constituted - 50%, DFS - 51.3%. In a univariate analysis among various risk factors (age <> 30y, initial risk group, WBC, LDH, immunophenotype, late response >35d, PRD resistance) age (>30 y) became statistically significant for OS, DFS and relapse probability (RP) (pic.1), abnormal karyotype - for DFS (30% vs 68%, p=0,04) and RP (42% vs 19%, p= 0,04). In a multivariate analysis no common risk factors were significant. Conclusions Our data demonstrate that the proposed treatment approach is rather effective. We believe that constant non-interruptive treatment without intensive highly myelosuppressive consolidation courses and high portion of allogeneic HSCT may become an alternative and reproducible approach in adult Ph-negative ALL, though we have to stress that it should be very strict compliance of the pts to the protocol. All pts, mostly from the region hospitals who refused prolonged and constant treatment (~5%), relapsed. Figure 1. Figure 1. Disclosures No relevant conflicts of interest to declare.

Abstract Abstract 32 Background: RIT based conditioning offers the potential of combining the efficacy of radiation with decreased toxicity over traditional TBI. In pilot trials we demonstrated that combining Yttrium 90 (ibritumomab tiuxetan) with high-dose BEAM (ZBEAM) is feasible and has a toxicity profile similar to high-dose BEAM. Herein we report the results of a comparative analysis designed to evaluate transplant outcomes among DLCL patients who were conditioned with either ZBEAM or a TBI-based conditioning regimen. Patients were matched on age (+/− 5 years), disease status, number of prior regimens, year of diagnosis (+/− 5 years), and year of transplant (+/− 5 years). There was a total of 92 DLCL patients treated from 01/1997-01/2009; 46 patients in each treatment group. The median patient age was 56.5 years (range: 19–78) for the ZBEAM group, and 53 years (range: 21–62) for the TBI group. Both groups had a median of two prior regimens, with 13% (ZBEAM) and 15% (TBI) considered high-risk first remission, 65% beyond 1st CR and 22% induction failures in each cohort. The median length of follow-up for surviving patients was 51–83 months. There was a trend toward improved PFS in the RIT group: 2 year PFS for ZBEAM group 66% (95%CI: 56–74) vs. 50% (95%CI: 43–57) for TBI group (p<0.08). Results to date show that a plateau in PFS appears to have been achieved for both groups (at 2.6 years in the ZBEAM group and 3.7 years for the TBI group), which translates into a 20% improvement in PFS for the ZBEAM patients, >4 years post transplant. Similarly the OS estimate was significantly higher for ZBEAM compared to TBI controls: 84% vs. 59 % (p<0.01). The lower OS rate for the TBI cohort was primarily due to toxicity, with a 2 year non relapse mortality of 0% for ZBEAM vs. 13% for TBI. (p<0.01) The causes of death included: relapse progression n=9 (ZBEAM), n=15 (TBI), infection n=2 TBI, cardiac disease n=2 TBI, pneumonia N= 1 TBI, unknown N=3 TBI. Conclusions: RIT based conditioning demonstrated improved survival when compared to traditional radiation based regimens in the treatment of DLCL due to a more favorable toxicity profile, while maintaining potent anti-lymphoma effects.

Background:Optic Neuritis (ON) is one of the most common clinically isolated syndromes which develops into clinically diagnosed Multiple Sclerosis (CDMS) over time.Objective:To assess the conversion rate of Iranian patients presenting with idiopathic ON to CDMS as well as monitoring potential demographic and clinical risk factors.Methods:Atotal of 219 patients' medical records of idiopathic ON from March 2001 to May 2009 were reviewed. Demographic findings, ophthalmologic characteristics on admission and discharge, diagnostic approaches, type and dosage of therapy were retrospectively reviewed. A structured telephone interview was then conducted to identify patients who had subsequently been diagnosed with MS. Survival analysis was used to evaluate the cumulative probability of MS conversion and contributory risk factors.Results:From the 219 ON patients, 109 [age 11-51, female: 81%] were followed up. Among the male gender the mean age of patients developing MS was significantly lower (P=0.01). In cox regression model, female sex (p=0.07), bilateral ON (p=0.003), MRI abnormalities (p <0.001) and high dose (5g) corticosteroid therapy (p<0.001) were identified as risk factors for the development of MS. The two and five year cumulative probability of developing MS were 27% and 45%, respectively.Conclusions:Idiopathic ON in Iranian patients carries higher risk of progression to MS compared to other Asian countries. MRI lesions are the strongest independent risk factor of developing CDMS. Bilateral ON, female gender and high dose corticosteroid therapy are also important factors in predicting CDMS development.

Abstract Abstract 409 Alteration of the IKZF1 gene – encoding the transcription factor IKAROS, a key player in lymphoid development and tumor suppression – has been reported to be associated with a poor outcome in pediatric precursor B-cell ALL, especially in cases positive for the BCR-ABL1 fusion gene. In order to assess the prognostic value of IKZF1 deletions in a representative cohort of pediatric ALL patients treated on the German ALL-BFM 2000 study protocol, we screened 409 patients by applying a multiplex ligation-dependent probe amplification (MLPA) assay covering all eight IKZF1 exons (P335-A3 ALL-IKZF1 probemix; MRC-Holland, Amsterdam, The Netherlands). In ALL-BFM 2000, risk group stratification (standard, SR; intermediate, MR; high, HR) was based on minimal residual disease (MRD) analysis at two different time points (TP) and required two MRD targets with sensitivities of ≤10−4 (Flohr et al. Leukemia 2008). SR patients were MRD-negative on treatment days 33 (TP1) and 78 (TP2). HR patients had residual disease (≥10−3) at TP2. MRD MR patients had positive MRD detection at either one and or both time points but at a level of <10−3 at TP2. Although MRD-based stratification criteria were introduced in ALL-BFM 2000, established high-risk parameters were also retained: patients with prednisone poor-response or ≥5% leukemic blasts in the bone marrow on day 33 or positivity for a t(9;22) or t(4;11) or their molecular equivalents (BCR/ABL1 or MLL/AF4 fusion RNA) were stratified into the high-risk group independent of their MRD results. First results on MRD and outcome were published earlier (Conter et al. Blood 2010). Out of the 409 patients analyzed in our study, 46 (11%) displayed a deletion in at least one of the eight IKZF1 exons. Forty-three out of the 46 cases showed heterozygous deletions, while 3 patients displayed homozygous loss of IKZF1 exons. MLPA results of 11 patients were validated with results derived from copy number/LOH analyses using Affymetrix SNP 6.0 arrays. IKZF1 deletion was significantly more common in precursor B compared to T cell ALL (13% vs. 4%, P = 0.03) and less frequent in TEL/AML1-positive ALL (3% vs. 13%, P = 0.004). Out of 11 BCR/ABL1-positive samples, only two were characterized by an IKZF1 deletion. Forty-four patients with IKZF1-deleted ALL had results of MRD analyses available for both informative time points (day 33 after induction and day 78 after consolidation). Despite a trend towards increasing incidence of IKZF1 deletion in patients with slow response, the distribution of IKZF1-deleted ALL patients over the risk groups was not significantly different from non-deleted ALL (SR: 40.9 vs. 41.9; MR: 45.5 vs. 52.3; HR: 13.6 vs. 5.7%; P = 0.153). Regarding treatment outcome, patients with an IKZF1 deletion had a significantly lower 5-year event-free survival (EFS) compared to non-deleted patients (0.78±0.06 vs. 0.86±0.02; P = 0.015). This result was due to a higher cumulative incidence of relapses in IKZF1-deleted patients (0.16±0.05 vs. 0.10±0.02; P = 0.031). In multivariate Cox regression analyses including known prognostic variables (gender, immunophenotype, WBC count at diagnosis, TEL/AML1 status, risk group criteria of ALL-BFM 2000), IKZF1 deletion conferred a risk of 2.16 (95% confidence interval 1.14 – 4.10; P = 0.018) for an event when compared to non-deleted patients. We conclude that IKZF1 deletion is an independent predictor of treatment outcome for patients enrolled on the ALL-BFM 2000 protocol and represents a candidate marker to be integrated in future algorithms for early risk stratification in pediatric ALL.

Abstract Background and Aims Infections remain an important contributor to the morbidity and mortality of immunosuppressive (IS) therapy in aggressive glomerulonephritis. We sought to investigate the infection profile and associated risk factors in a compiled cohort of patients with lupus nephritis (LN), cryoglobulinemic vasculitis (CryoVas) and ANCA-associated vasculitis (AAV) treated with induction and maintenance IS regimens. Method A total of 162 patients (101 with LN, 24 with CryoVas and 37 with AAV) were retrospectively reviewed for any infection that occurred from initiation of induction therapy. Infections were graded (1-5) according to the Common Terminology Criteria for Adverse Events. Infection site and type of microorganism were also recorded. Univariate and multivariate Cox proportional hazard regression analysis were performed in order to identify independent risk factors for infection. Results Eighty-two patients (50.6%) had at least one infection with a total 179 episodes of infection occurring during a median follow-up of 12 months (IQR:4-36.25 months). The majority of patients (64 of 82) had infections during the first 24 months since IS treatment initiation with a 24-month infection-free rate of 55%. The most common site was lung infection (in 32.7% of patients), while 39.5% of patients had bacterial infections (1.8% with Mycobacterium tuberculosis). 36.7% of patients had severe infections (grade 3 or higher) with 4.4% of infection-related deaths (8 patients). The most common induction regimen was cyclophosphamide in addition to corticosteroids (62%), while 43% received either mycophenolate mofetil or azathioprine in addition to corticosteroids as a maintenance regimen. In univariate Cox regression analysis, chronic obstructive pulmonary disease (HR 3.91; 95% CI, 1.76-8.68, p=0.001), pulmonary involvement in the setting of systemic disease (HR 2.35; 95% CI, 1.26-4.37, p=0.007), pulse methylprednisolone (HR 2.7; 95% CI, 1.7-4.31, p=0.001) and high-dose (≥30 mg/day) oral corticosteroids (HR 3.38; 95% CI, 2.11-5.43, p=0.001) were risk factors for infection. In multivariate Cox regression analysis, high-dose oral corticosteroids (HR 2.67; 95% CI, 1.5-4.76, p=0.001) remained an independent predictor of infection risk. Of the risk factors associated with severe infections (grade 3 or higher), in univariate analysis we identified pulmonary involvement in the setting of systemic disease (HR 3.65; 95% CI, 1.72-7.77, p=0.001), pulse methylprednisolone (HR 3.56; 95% CI, 1.7-7.3, p=0.001), high-dose (≥30 mg/day) oral corticosteroids (HR 3.56; 95% CI, 1.77-7.16, p=0.001), estimated GFR (HR 0.98; 95% CI, 0.98-0.99, p=0.01) and AAV (by comparison to CryoVas and LN) (HR 2.81; 95% CI, 1.39-5.66, p=0.004) as risk factors for infection. After multivariate adjustment, pulmonary involvement in the setting of systemic disease (HR 2.38; 95% CI, 1.01-5.73, p=0.05) and high-dose oral corticosteroids (HR 2.44; 95% CI, 1.04-5.72, p=0.04) were identified as independent predictors of infection risk. Conclusion Infections occur frequently with current immunosuppressive regimens in aggressive glomerulonephritis. In addition to pulmonary involvement in the setting of systemic disease, a high dose corticosteroid regimen was the most significant risk factor for infection.

Abstract Background: The introduction of rituximab into the therapy of DLBCL has improved the prognosis dramatically. However, relapse in CNS is still the issue. We studied the prognosis and risk factors of CNS recurrence in DLBCL. Method: Between Jan. 1996 and Apr. 2007, 441 patients were diagnosed to have DLBCL in our institute, of whom 31 patients were excluded due to CNS involvement at the time of initial diagnosis. We have analyzed 410 cases, in which 37 cases had relapsed in CNS. Before Sep. 2003, 168 patients were treated with the regimen based on CHOP, and after Sep. 2003, 242 patients were treated with the regimen based on CHOP plus rituximab. Once relapsing in CNS, the patients were treated with systemic chemotherapy plus high-dose methotrexate or radiation with intrathecal methotrexate. The risk category by the international prognostic index of these 411 cases was assessed as low: 36%, low-intermediate: 15%, high-intermediate: 23%, and high: 26%. Results: The median age was 71 years old (range: 17–92). Median follow-up period was 507 days, and the median period free from relapsing in CNS was 331 days. The mean survival period of the cases with CNS relapse, of the cases relapsed outside the CNS, and of the non-relapsed cases was 1328 days, 2290 days, and 2817days, respectively. The overall survival rate of cases with CNS relapse was significantly lower than that of the cases relapsed outside the CNS, or than that of the non-relapsed cases (p=0.0233, p=0.0003, respectively). Multivariate Cox regression analysis identified the increased lactate dehydrogenase (p=0.014), the involvement of more than one extranodal site (p=0.006), and not using rituximab before CNS relapse (p=0.040) as an independent predictor of CNS recurrence. Conclusion: CNS relapse has extremely poor prognosis than relapse outside the CNS in DLBCL. Rituximab may be effective in preventing CNS relapse. Since rituximab poorly penetrates into CNS, this may partly due to the reduction of all recurrence by rituximab. According to the risk assessment in CNS relapse, an effective CNS prophylaxis strategy should be determined.

Abstract Abstract 1288 Recurrence or persistence of disease after hematopoietic cell transplantation (HCT) remains a significant obstacle in the treatment of patients with acute myeloid leukemia (AML) and high risk myelodysplastic syndromes (MDS). Standard therapies for relapsed disease include withdrawal of immunosuppression (WIS), donor lymphocyte infusion, induction chemotherapy, and in selected patients, a second HCT. Regardless of the intervention chosen, survival for post-transplant relapse has been dismal. Effective therapies without significant toxicity are needed. Azacitidine, a DNA demethylating agent, is the only non-HCT therapy shown to prolong survival in patients with MDS. It has also shown efficacy in patients with AML when used alone as induction or consolidation therapy or in combination with the anti CD-33 antibody gemtuzumab. Its use following HCT was inspired by the discovery of the drug's potential to enhance the graft-versus-leukemia effect through demethylation of the KIR regions on donor NK cells and by enhancing HLA-DR2 expression on leukemic blasts. It has also been shown to modulate T-cells post-engraftment and may result in lower rates of GVHD without impairing the GVL effect. Several small case series have been published evaluating azacitidine as therapy for treatment of relapse following HCT and have demonstrated improvement in disease status. None of these studies have examined azacitidine in the setting of persistent disease, which has become more relevant with the use of lower intensity conditioning regimens and the use of new methods to detect the presence of disease at extremely low levels. In this retrospective study, we determined the outcomes of patients treated with azacitidine (75 mg/m2/day for 7 days +/− gemtuzumab (3mg/m2) on day 9, every 4 weeks) for post-HCT recurrence or persistence of AML/MDS. Azacitidine treatment was initiated following HCT if there was evidence of recurrent or persistent disease (defined as any recurrent abnormal blasts detected by flow on peripheral blood or marrow or recurrent cytogenetic abnormalities). Seventeen (74%) of the patients had AML while 6 (26%) had MDS. FAB subtypes of the latter included RAEB (3), RA (1), CMML (1) and unclassified (1). Eighteen (78%) patients underwent conventional high dose conditioning, and 5 (22%) patients underwent nonmyeloablative conditioning prior to HCT. Eleven (48%) of patients had low risk cytogenetics, 3 (13%) had intermediate risk, and 9 (39%) had high risk cytogenetics. Seventeen (74%), 0 (0%) and 6 (26%) of patients were diagnosed with persistent or relapsed disease within 100, 100–200 and > 200 days following HCT. Patients began azacitidine 0–242 (median: 17) days from time of relapse and completed a median of 2 azacitidine cycles (range 1–8). Overall 6-month survival from the day of relapse was 57% and from start of azacitidine therapy was 48%. Among the 18 patients who started azacitidine within 2 months of documented relapse the 6-month survival was 50%. Blast count at time of relapse was not significantly associated with survival (> 1% vs ≤ 1%, HR=1.26, p=0.63), nor was survival after initial treatment with azacitidine affected by longer time intervals prior to first administration (> 28 days vs ≤ 28 days, HR=0.85, p=0.76). There were 12 patients who received gemtuzumab with azacitidine, and the addition of gemtuzumab made no difference in survival (HR with gemtuzumab = 0.81 (0.3-2.1), p=0.66). The 6-month survival with azacitidine is superior to that observed with induction chemotherapy (20%) or WIS (10%). Azacitidine therapy may be superior to standard therapies for recurrent/persistent disease following HCT and warrants further study. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 368 Background: TT3, incorporating bortezomib and thalidomide with induction prior to and consolidation after melphalan 200mg/m2-based transplants and 3 year maintenance with VTD (year 1) and TD (years 2+3) in TT3A and with VRD for 3 years in TT3B resulted in a high CR rate of ∼60% and, in the 85% of patients with GEP-defined low-risk MM, 5-yr OS/EFS of 80%/78%; 5-year CR duration estimate was 88%. Patients and Methods: Phase III trial TT4 for low-risk MM randomized patients between standard (S) and light (L) arms. TT4-L applied 1 instead of 2 cycles of induction therapy with M-VTD-PACE prior to and 1 instead of 2 cycles of consolidation with dose-reduced VTD-PACE after tandem transplantation. M-VTD-PACE comprised melphalan, bortezomib, thalidomide, dexamethasone and 4-day continuous infusions of cisplatin, doxorubicin, cyclophosphamide, etoposide. TT4-S applied standard single dose melphalan 200mg/m2, while TT4-L used a 4-day fractionated schedule of melphalan 50mg/2 on days 1–4. VRD maintenance for 3 years was identical in both arms. Here we report, for both TT4 arms combined, on grade >2 mucosal toxicities, applying CTCAE version 3.0, and on efficacy (CR, EFS, OS) in relationship to TT3 in low-risk MM. At the time of analysis, median follow-up on TT4 is 10.7 months and on TT3A/B 62.3/33.4 months. To facilitate comparisons between trials with different follow-up times, TT3 data were backdated to follow-up time comparable to TT4 as of this reporting time. Results: Baseline characteristics were similar in TT3 (n=364) and TT4 (n=165) in terms of B2M both >=3.5mg/L and >5.5mg/L, and elevated levels of CRP, creatinine, and LDH. Presence of cytogenetic abnormalities (CA) overall and in terms of CA13/hypodiploidy was similar in both. Fewer TT4 patients had ISS-1 (31% v 43%, P=0.010) and more had hemoglobin <10g/dL (35% v 26%, P=0.029). While neither trial had GEP-defined high-risk in the 70-gene model (R70), the more recently validated R80 distribution showed 7% high-risk in TT4 v 3% in TT3 (P=0.031). DelTP53 was more prevalent in TT4 than TT3 (39% v 10%, P<0.001), and MY favorable subgroup designation pertained to 3% in TT4 v 12% in TT3 (P=0.002). Toxicities are reported per protocol phase. During induction (TT4, n=160; TT3, n=364), grade >2 mucosal toxicities included colitis in 0%/1% (P=0.32), esophagitis/dysphagia in 0%/1% (P=0.33), GI mucositis, NOS in 1%/1% (P=0.99) and stomatitis/pharyngitis in 0%/1% (P=0.99). With transplant-1, (TT4, n=139; TT3, n=344), grade >2 mucosal toxicities included colitis in 3%/1% (P=0.24), esophagitis/dysphagia in 1%/5% (P=0.03), gastritis in 1%/0% (P=0.29), GI mucositis, NOS in 1%/2% (P=0.73) and stomatitis/pharyngitis in 0%/5% (P=0.008); with transplant-2 (TT4, n=105; TT3, n=294), grade >2 mucosal toxicities included colitis in 4%/3% (P=0.77), esophagitis/dysphagia in 0%/2% (P=0.20), GI mucositis, NOS in 2%/3% (P=0.99) and stomatitis/pharyngitis in 0%/1% (P=0.58). With consolidation (TT4, n=85; TT3, n=280), grade >2 mucosal toxicities included colitis in 0%/3% (P=0.36) and GI mucositis, NOS in 0%/1% (P=0.99). Timing of onset and final levels of CR differed substantially between TT4 and TT3 in favor of TT4 (P=0.006); no differences were observed in OS (P=0.36), EFS (P=0.66), and CR duration (P=0.12). Conclusion: TT4 (both arms combined) provided, despite higher proportions of patients with unfavorable characteristics than in TT3, superior CR rate and comparable survival outcomes to TT3's low-risk population. GI toxicities were reduced in TT4 v TT3. Results of TT4 arms will be presented. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 678 Background: Umbilical cord blood transplant (UCBT) recipients are high risk for cytomegalovirus (CMV) complications due to delayed and insufficient immune reconstitution. Since CMV viral load has been shown to be associated with the development of disease, an intensified prevention strategy was adopted at the FHCRC (Seattle, WA) which consists of pre-transplant ganciclovir (from day -8 to day -2), and high-dose acyclovir ([HDA] 2 gm valacyclovir 3 times daily) with preemptive bi-weekly monitoring for CMV DNA in serum from day 0 until day +100. Methods: We set out to compare rates of CMV reactivation and disease through day +100 in high-risk CMV seropositive UCBT recipients who received either the intensified strategy (G+HDA) or standard dose of acyclovir/valacyclovir (SDA, acyclovir 800 mg or valacyclovir 500 mg twice daily). All patients underwent weekly plasma testing for CMV by polymerase chain reaction (PCR). Our primary outcomes of interest were any CMV reactivation or disease by day 100. Risk factors for CMV reactivation were assessed using a multivariate Cox proportional hazards model. Results: Of the 105 UCBT recipients transplanted at the FHCRC between 1/2006 and 12/2009, 61 (58%) were CMV seropositive and eligible for inclusion in the cohort. In total, 31/61 (51%) received SDA and 30 (49%) G+HDA. The median patient age was lower in the SDA group 21.3 (interquartile range [IQR] 14.8–46.7) years and 30.1 (IQR 10.1–41.8) for G+HDA group, but other demographic factors were similar. Overall, the cumulative incidence of CMV reactivation was significantly lower in the G+HDA group (60% vs. 96.7; p=0.001 [Gray's test]) (Figure 1). In patients receiving G+HDA, the median time to first positive CMV PCR occurred later (27 days [IQR 11–35]) when compared to those given SDA prophylaxis (17 days [IQR 8–25]) (p=0.26). Additionally, the G+HDA group had significantly lower initial (71 copies/mL [IQR 47–110] vs. 235 [IQR 63–760], p=0.006) and maximum PCR viral loads (VL) (170 copies/ml [IQR 88–310] vs. 3200 [1400-11000], p<0.001) when compared to those receiving SDA prophylaxis. In multivariate analyses, the G+HDA prophylactic strategy was also associated with a significant reduction in CMV reactivation (HR 0.31; 95% CI 0.16–0.58; p<0.001). Over the first 100 days following transplant, there were fewer episodes of invasive CMV disease in the G+HDA group (1/30, 3% [1 pneumonia]) than under SDA prophylaxis (5/31, 16% [1 disseminated, 2 pneumonia, and 2 GI]) (p=0.09). In the SDA group 2/5 (40%) patients died secondary to CMV disease, and an additional 2 patients developed fatal CMV pneumonia after day 100 (day 165 & 191); no CMV related death or cases of late disease developed in the group receiving G+HDA prophylaxis. There was no evidence of increased toxicity by either median and maximum creatinine levels or days to engraftment when comparing the two regimens. Conclusions: Our study demonstrates that G+HDA was effective in preventing CMV complications in UCBT recipients. This intensified prevention strategy was associated with a decreased rate of CMV reactivation and appeared to significantly alter CMV replication dynamics. Importantly, the increased valacyclovir exposure did not alter the risk for developing either renal or hematologic toxicity. Disclosures: No relevant conflicts of interest to declare.
