Abstract Background: Lymphoma patients with residual hypermetabolic lesions on FDG-PET imaging after salvage chemotherapy have poor outcomes following autologous stem cell transplant (ASCT). We have previously shown progression free survival (PFS) of only 5 months (range: 1-19) in this population with only 7% of patients without progression at 12 months (Svoboda et al, BMT 2006). We hypothesized that these high-risk patients may benefit from continued therapy after ASCT. Lenalidomide is an immunomodulatory agent which has been used as maintenance in other hematologic malignancies, but its toxicity and efficacy have not been well described in lymphoma patients following ASCT. Methods: We are conducting a phase I/II prospective, open-label trial of lenalidomide maintenance after ASCT in lymphoma patients at high risk for relapse defined by residual FDG-PET positive lesions (SUV ≥ 2.5) immediately prior to ASCT. The primary objective of phase I was to determine the safety and dose-limiting toxicity (DLT) of lenalidomide maintenance. A 3+3 de-escalation design was used with a starting dose of lenalidomide at 10 mg on days 1 through 28 of each 28-day cycle. Lenalidomide was initiated 28-100 days post-ASCT and planned for up to 24 cycles. DLT was defined as non-hematologic toxicity ≥ grade 3 or hematologic toxicity ≥ grade 4 during the first 28 days of lenalidomide. The primary objectives of phase II were PFS and overall survival (OS). Survival outcomes were calculated from the date of ASCT. Enrollment began in 5/2012; we report data through 7/2016. Results: Fourteen patients were enrolled and 11 were evaluable (one patient withdrew consent and two progressed prior to initiation of lenalidomide). Eight (73%) evaluable patients had diffuse large B-cell lymphoma (DLBCL): 4 with germinal center (GC) origin and 4 non-GC by Hans algorithm. Three (27%) patients had Hodgkin lymphoma. Median age was 44 years (29-61), ECOG PS 0 (0- 1), prior therapies 2 (2-5). Median follow-up was 24 months (range 8-44), and median time on lenalidomide was 13 cycles (1-24). No DLTs were observed in phase I, and the dose of 10 mg daily was determined to be appropriate for phase II. Six (55%) patients discontinued lenalidomide: 3 due to disease progression, 2 at investigator's discretion (1 subsequently progressed), and 1 due to grade 3 rash possibly related to lenalidomide. Of 3 patients who discontinued lenalidomide due to progression, 1 (non-GC DLBCL) died of disease progression, 1 (GC DLBCL) achieved complete remission (CR) with allotransplant, and 1 (non-GC DLBCL) remains on another active therapy. Overall, 8 (73%) patients remain in CR following ASCT, including 3 patients who discontinued lenalidomide. Of note, 1 patient developed adenocarcinoma of the colon 1 year after completion of lenalidomide, and 1 patient developed therapy-related acute myeloid leukemia at 10 months after discontinuing lenalidomide. At a median follow-up of 24 months, PFS of the complete cohort was 62.3% (95% CI: 0.28-0.84; Figure 1) and median PFS was not reached. OS was 75% (95% CI: 0.30-0.93; Figure 2) and median OS was not reached. When compared to the reported PFS of 7% at 12 months in the historical controls with identical high risk pre-transplant characteristics, the PFS of 62.3% (95% CI: 0.28-0.84) at 12 months was significantly improved (Z-test, p<0.05). Conclusion: We established feasibility of lenalidomide maintenance at 10 mg daily after ASCT in patients with relapsed/refractory lymphomas. Preliminary clinical outcomes observed in this phase I/II trial are very encouraging when compared to historical controls. To better understand the toxicity profile and validate the promising clinical benefit, the strategy of utilizing immunomodulatory agents as post-transplant maintenance should be studied in a larger cohort of high-risk lymphoma patients.

Introduction: Patients with high-risk multiple myeloma (HRMM) who have undergone autologous stem cell transplant (ASCT) will inevitably relapse and have a progression free survival (PFS) ranging from 8-14 months (Gaballa et al, American Journal of Hematology, 2016) and 24-39 months while on lenalidomide (Len) maintenance therapy (Jackson et al, The Lancet Oncology, 2019). Unlike in solid tumors, PD-1 blockade has no single agent activity in relapsed and refractory multiple myeloma (MM) patients suggesting that immune stimulating agents, immunomodulatory agents (IMiDs), such as lenalidomide (Len) or pomalidomide (Pom) are necessary in combination with anti-PD-1 blockade to increase depth and duration of response post-ASCT. The Keynote-023 study revealed an overall response rate (ORR) of 76% with the combination of pembrolizumab (Pem), Len and dexamethasone (Dex). Similarly, the Keynote 135 study using the combination of Pem, Pom, and Dex revealed an ORR of 60%. Unfortunately, the phase III studies comparing an IMiD vs Pem with the IMiD upfront at the early relapsed setting were halted because of increased deaths on the Pem arm and a decreased median PFS. With our Phase II study currently on clinical hold by the FDA, we are presenting here the 2-year follow-up of the original patient cohort including some preliminary safety and efficacy data of Pem-Len-Dex in HRMM patients as post-ASCT consolidation (NCT02906332). Methods: Patients with HRMM who have undergone induction therapy followed by single or tandem melphalan-based ASCT were considered eligible 2-6 months post ASCT. HRMM criteria are defined by any of the following: ISS stage 3; del 13q by cytogenetics; FISH with 1q amplification, 1p deletion (del), p53 del, t(4;14), t(14;16), t(14;20), hypodiploidy; or a high-risk gene expression profile score. Patients were excluded if they had progression of disease at time of screening or if there was evidence of organ dysfunction. Patients received Pem 200 mg IV at day 1;Len 25 mg po daily at days 1-14; and Dex 40 mg daily at days 1,8,15 of a 21-day cycle for a total of 2 cycles and then an additional 2 cycles of Pem + Len without Dex at the same dose and frequency. Survival outcomes post-ASCT were measured using the log-rank test. Results: Of 15 patients screened, 12 received at least one dose of therapy and were deemed evaluable. One patient withdrew consent and did not follow up after cycle 2. Baseline characteristics are shown in Table 1. Thirty-three percent were ISS 3, 66.7% had a p53 deletion by FISH, 41.6% received induction Bortezomib-Len-Dex; 33% received induction Carfilzomib-Len-Dex, and the remaining 24.9% received other bortezomib-based induction. Best ORR during the 2 year follow up showed 8 patients (73%) achieving stringent complete remission, 2 patients (18%) showing complete remission and 1 (9%) achieving very good partial remission. Table 2 shows best response to treatment by cycle of therapy. Table 3 shows best response during follow-up visits, which were 3 months apart. Of the 11 patients who completed therapy, 8 had minimal residual disease (MRD) status assessed and among them, 7 were MRD negative by flow cytometry, tested 30 days after the fourth cycle. With a median follow-up of 32.2 months, median PFS was 27.6 months. The PFS rates at 1 year and 2 year are 91.3% and 65.2%, respectively. All patients had adverse events (AEs), AEs were attributed to Pem, Len, or Dex rather than from ASCT. Of the 90 AEs that were reported, 5.6% were grade 3 and 94% were grade 1 or 2 (Table 3). The most common hematologic AE was neutropenia (41.7%), with 3 pts (25%) grade 1 and 2, and 2 pts (16.6%) grade 3. The most common non-hematologic AEs were intermittent constipation (16.6%), diarrhea (16.6%), fatigue (8.3%), and increased ALT (8.3%) and were graded as 1 or 2. Non-hematologic grade 3 AEs occurred in 2 pts and included hypoxia and maculopapular rash. There was 1 serious AE, H. influenza pneumonia requiring inpatient admission, which was not considered to be related to Pem. Conclusions: The combination of Pem, Len, and Dex given to HRMM patients in the post-ASCT consolidation setting is well tolerated. In comparison to historical controls of HRMM patients post-ASCT with a median PFS of 8-14 months, the PFS rates of 91.3% and 65.2% at 1 and 2 year post-ASCT respectively suggest an efficacy signal for the use of Pem, Len, and Dex as post-ASCT consolidation. Larger prospective studies are needed to validate these results.

Abstract Abstract 617 Background: The VDD treatment regimen has been shown to be highly effective as initial therapy for multiple myeloma. Given the established synergy between bortezomib and alkylating agents, incorporating an alkylator to VDD may increase the depth of response and may improve long term outcome. We report the results from a Phase I trial combining VDD with escalating doses of cyclophosphamide ( CVDD) in patients (Pts) with newly diagnosed myeloma. Methods: Pts received Bz 1.0–1.3 mg/m2 on days 1, 4, 8, 11, DOX 30mg/m2 on day 4, Dex 20 mg on days 1, 2, 4, 5, 8, 9, 11, 12 and Cy 250-750 mg/m2 on day 1, for up to eight 21-day cycles, at four planned dose levels (Cy/Bz: 250/1.0, 500/1.0, 750/1.0, 750/1.3). Dose-escalation proceeded (three-pt cohorts) depending on dose-limiting toxicities (DLTs) grade 3 non-hematologic toxicity; thrombocytopenia with platelets <10,000/mm3 on >1 occasion despite transfusion support; Grade 4 neutropenia for >5 days and/or resulting in neutropenic fever; inability to receive cycle 2/day 1 dose due to drug-related toxicity). Pts with Grade 2 peripheral neuropathy (PNY) were excluded. Responses were assessed by International Working Group criteria. Pts with at least partial response ( PR) and standard risk cytogenetics could proceed to autologous stem cell transplant (ASCT) after 6 cycles. Responsive pts with high risk cytogenetics defined as the presence of one of the following at diagnosis; deletion of chromosome 13 by cytogenetics, hypodiploidy, or t (4;14), t(14;16) or deletion of 17 p by FISH, completed 8 cycles of therapy. Results: 26 pts have been enrolled to date: 12 in phase l, and 14 additional pts at the maximum planned dose (MPD). Median age 60 yrs, 62% men, 50% IgG MM, 81% with ISS stage II/III. Pts have received a median of 6 cycles; 17 have completed all 6-8 cycles, 1 has discontinued therapy. No DLTs were observed in the phase I portion of study. Dose reductions in cycle 2 and beyond have occurred in 31% of patients. Toxicities to date have been manageable, including all Grade 3/4 hematological toxicities (4-35%), Grade 3 hand foot syndrome( 15%), Grade 3 pneumonia (8%), Grade 3 UTI (8%), and Grade 3/4 metabolic (19%). There were no grade 3/4 PNY. There was 1 treatment-related mortality secondary to infection. The overall response rate in patients that have completed at least 4 cycles of therapy (ORR; ≥PR) is 90%, including 57% ≥VGPR, and 24% CR. ORR and VGPR rates were similar in patients with standard or high risk cytogenetics. Nine patients have proceeded to transplant and all have had successful stem cell mobilization with G-CSF alone. Conclusions: CVDD produces high quality responses and is well tolerated in newly diagnosed MM pts, regardless of their cytogenetic status or ISS stage. MPD has been reached at CY 750 mg/m2, Bz 1.3 mg/m2, DOX 30 mg/m2, and Dex 20 mg, with phase II enrollment ongoing. Stem cell mobilization has been successful in all pts, with transplant course in pts otherwise unremarkable. Updated efficacy will be presented at the meeting.

Abstract Background: HDT-ASCT with TBC conditioning has emerged as a common consolidation strategy for patients (pts) with relapsed/refractory (rel/ref) primary (PCNSL) or secondary (SCNSL) (Welch et al, Leuk & Lymph 2014). In a prospective study, chemosensitive PCNSL pts in first remission after induction with R-MPV (rituximab, MTX, procarbazine and vincristine) proceeding to HDT-ASCT with TBC conditioning, experienced an encouraging 2-year PFS and OS of 75% and 81%, respectively (Omuro et al, Blood, 2015). Three of these patients experienced transplant-related mortality (TRM, 11.5%), which appears greater than HDT-ASCT for other lymphomas. The purpose of this report is to correlate characteristic toxicities of TBC conditioning for CNSL to pre-HDT-ASCT clinical variables. Methods: The MSKCC IRB approved this retrospective chart review. Eligible pts (n=34) were ≥ 18 years of age with PCNSL or SCNSL that was chemosensitive to induction therapy after which they proceeded to HDT-ASCT conditioned with TBC between December 2006 and April 2015. All pts included were treated outside of prospective clinical trials. Clinically significant grade 3-5 non-hematologic toxicities per CTCAE 4.0 occurring in >20% of pts were recorded from the initiation of conditioning until 6 months post ASCT (Figure 1). Pre-HDT-ASCT variables for analysis include: age, gender, disease (PCNSL or SCNSL), Karnofsky performance status (KPS), hematopoietic cell transplant comorbidity index (HCT-CI), number of prior regimens, prior use of whole-brain radiotherapy (WBRT), and disease status prior to HDT-ASCT (CR/CRu or PR). We evaluated the association of these pre-HDT-ASCT characteristics with the number of clinically significant grade 3-5 non-hematologic toxicities (≥4 vs. <4) using FisherÕs exact test. We further estimated progression-free survival (PFS) and overall survival (OS) using Kaplan-Meier methods. Results: Thirty-three patients (97%) experienced ≥ 1 grade 3-5 non-hematologic toxicity. Febrile neutropenia (grade 3) occurred in 32 pts (94%). Of all pre-HDT-ASCT variables, only the number of prior regimens (>2) was significantly associated with incurring more grade 3-5 non-hematologic toxicities, p=0.04 (Table 1). With a median follow-up for survivors of 12 months (range, 1.5-86.2 months), PFS was 79% (95% CI, 65-96) and OS was 82% (95% CI, 68-98) at 1 year (Figures 2 and 3). During the follow-up period, there were 7 pt deaths: 4 died of disease, 2 died secondary to TRM (5.9%), and one died of a secondary malignancy (squamous cell carcinoma) 86.2 months after HDT-ASCT. There were no progression events beyond 12 months. In a limited subset analysis wherein n=22 had first dose bu pharmacokinetics evaluated, pre-HDT-ASCT variables were not associated with higher bu AUC levels, though 64% of these pts required a dose reduction. Conclusions: We reaffirmed that HDT-ASCT with TBC conditioning is effective consolidation for CNSL, but it is associated with more grade 3-5 non-hematologic toxicity in pts having had >2 prior regimens. Risk-adapted dose attenuation of TBC conditioning for this group of pts may mitigate observed toxicity. Table 1.

Abstract Introduction: In younger patients that are transplant-eligible, autologous stem cell transplant (ASCT) prolongs overall survival based on several prospective randomized control trials. Nevertheless, ASCT is not a curative approach and majority of the patient's relapse, requiring further salvage therapeutic options. However, in the face of an ongoing paradigm shift in myeloma therapeutics, there is a significant knowledge gap regarding how patients relapse following ASCT. We analyzed the patterns of relapse among myeloma patients after ASCT. Methodology: We have evaluated a total of 975 patients that underwent ASCT during the period January 2008 through June 2014 from our myeloma database. 273 patients had documented evidence of first relapse post-ASCT on the laboratory parameters, radiologic or pathologic findings based on IMWG criteria for relapse. We categorized the relapses as biochemical vs symptomatic, and described their frequencies and characteristics. Median time of follow up from diagnosis is 68 months and from ASCT is 54 months. We used IBM SPSS version 23.0 to generate the survival statistics. Results: Median time from ASCT to relapse is 20 months. A total of 182 (66.7%) patients (105M, 77F) experienced biochemical relapse, while 91 (33.3%) patients (50M, 41F) had symptomatic relapse. More IgA patients (30.8% vs 23.1%, p=0.06) relapsed as symptomatic myeloma. While characterizing relapses, we did not find any differences in symptomatic relapses by the risk group [high risk (31.3%) vs standard risk (31.9%), p=0.193, ISS stage I (29.3%) vs II (32.9%) vs III (32.8%), p=0.807] or by maintenance [yes (30.7%) vs no (38.1%), p=0.211]. Among the patients that had a symptomatic relapse, presence of new bone lesions (52%) and anemia (42%) are the most common forms of relapse seen. Only 4% presented as hypercalcemia and 1% presented as renal failure illustrating the benefits of closer follow up. Overall survival is similar among patients that relapsed as biochemical or symptomatic relapse (log rank, p=0.105). More importantly, impressive median OS of 145 months from the ASCT among this entire cohort (at median follow up 54 months, figure 1). Conclusions: Two-thirds of the patients relapse as a biochemical relapse post-ASCT. The patterns of biochemical vs symptomatic relapses were similar among patients by maintenance, by risk status and also by the ISS stage. The significant improvement in OS among the entire cohort emphasizes the power of the new therapeutic salvage strategies aimed at gaining the survival advantage even among this selected group of patients undergoing early relapses.

Introduction: Patients (pts) with high-risk multiple myeloma (HRMM) experience early disease progression post autologous stem cell transplant (ASCT). The median progression free survival (PFS) for HRMM pts undergoing ASCT with lenalidomide (len) maintenance ranges between 27 and 42 months in high risk pts and 22 months in ultra-high risk, defined by two or more adverse cytogenetic abnormalities such as: gain(1q), t(4;14), t(14;16),t(14;20), or del(17p)( Chakraborty et al, Leukemia,2018 and Jackson et al, Lancet, 2018). Elotuzumab, a humanized IgG kappa monoclonal antibody against SLAM-F7 (CS-1), is approved in combination with len and dexamethasone (ERd) in pts with relapsed MM (Dimopoulus et al, BJH, 2017). It directly activates natural killer (NK) cells and mediates myeloma cell death by antibody-dependent cell mediated cytoxicity. We hypothesized that administration of ERd as post-ASCT consolidation will enhance an immune-competent phenotype, by restoring NK cells and effector T-cell populations at a time of maximal disease de-bulking, and will ultimately improve outcomes among pts with HRMM. Methods: Thirty-one HRMM patients who achieved stable disease or better were treated beginning at 30-90 days post ASCT with ERd (29/31 pts) or elotuzumab/pomalidomide )/dex (EPd) (2/31 pts) between September 2016 and February 2019. With institutional review board approval, electronic medical records were reviewed for baseline characteristics, treatment history, adverse events (AE) while on therapy as defined by common terminology criteria for adverse events (CTCAE), and survival outcomes. Treatment with ERd or EPd was administered for 4 consecutive 28-day cycles per standard dosing regimens with a tapering or discontinuation of corticosteroids per investigator discretion with cycles 3 and 4. HRMM was defined by any of the following: ISS or Revised-ISS stage 3, CD-138 selected FISH with del 17p, 1q21 gain, t(4;14), t(14;16), and t(14;20), cytogenetics with 13q del or complex karyotype, and/or high-risk gene expression profile score. Ultra-HR pts were defined by having both del 13q and 1q21 gain by FISH based on recent unpublished COMPASS data. Minimal residual disease (MRD) was evaluated upon achievement of very good partial remission or complete remission using 10-color multiparametric flow cytometry. PFS was measured using the log-rank test. Response criteria was defined per International Myeloma Working Group criteria. Results: Baseline characteristics of all 31 patients are shown in Table 1. Thirty-four percent were ISS-3, 71% (22/31 pts) had high-risk FISH, of which 19% were ultra-high risk (6/22 pts). Seven pts (22.6%) underwent tandem-ASCT pre-consolidation. Of the 8 pts who had GEP testing, 2 (25%) were high risk. Best response to treatment by cycle is depicted in Table 2. Consolidative ERd/EPd deepened response compared to post-ASCT with 71.4% vs 19.4% achieving stringent complete remission (sCR). Post-consolidation, 19.3% vs 12.9%, pre-consolidation, achieved MRD negativity. With a median follow-up of 24.8 months, median PFS was 31.4 months (Figure 1). There was no significant association between median PFS and variables such as tandem ASCT and ultra-HR using multivariate cox regression. Although all pts experienced at least one AE while on therapy, only 1 patient (3.22%) experienced a grade 3 AE. Hematologic AEs included: anemia (48%), neutropenia (45%), and thrombocytopenia (52%), while the most common non-hematologic AEs included: fatigue (32%), malaise (23%), and back pain (19%). One patient experienced a serious AE (SAE) which was PCP pneumonia requiring hospitalization, resulting in early discontinuation from therapy. There was no treatment-related mortality. Conclusion: ERd or EPd as 4 months of fixed duration consolidation therapy post-ASCT resulted in a median PFS of 31.4 months amongst pts with HRMM, similar to or perhaps surpassing historical reports of HRMM pts receiving lenalidomide maintenance until progression. This therapy may offer comparable, if not superior, outcomes while having the advantage of allowing for significant time without therapy and perhaps improving quality of life and financial toxicity. This study is limited due to its retrospective nature. Larger prospective studies evaluating fixed duration ERd/EPd in HRMM patients post ASCT should be conducted.

8013 Background: The 5-year overall survival (OS) for pts with relapsed chemosensitive DLBCL with standard transplantation is approximately 40–50%. We previously piloted the addition of standard outpatient radioimmunotherapy (RIT) with 131-I tositumomab to the transplant regimen for patients with relapsed chemoresistant NHL. This phase I study demonstrated a 3 yr OS of 55% in these poor prognosis patients (JCO 23: 461–467, 2005). The current study is a follow-up phase II study in good prognosis relapsed and high risk DLBCL patients using 131-I tositumomab with BEAM (BCNU, etoposide, cytarabine, and melphalan) followed by an autologous stem cell transplant. Methods: Forty patients were accrued to the study between 2000–2005. The patients had a median age of 54 yrs (26–75) and all had a diagnosis of DLBCL. The patients had a median of two prior chemotherapies before transplant and 88% had received prior Rituximab. All patients had chemotherapy sensitive disease at the time of stem cell transplant. Following stem cell collection, all patients received a stem cell preparative regimen of 75 cGy total body dose of 131-I tositumomab (dosimetric dose day -19 and therapeutic day -12) followed by a standard BEAM transplant regimen. Autologous unpurged stem cells were infused on day 0. The median time of follow-up of the survivors is 28 months (3–68). Results: Seventy eight percent of the patients had a complete remission following the transplant. The 3 year progression free survival (PFS) is 70% (95% CI - 48 - 84%) and the 3 year OS is 81% (95% CI - 61 - 91%). The entire transplant can be delivered on an outpatient basis. No increased toxicity compared to a similar cohort receiving BEAM alone could be detected. Conclusions: The addition of 131-I tositumomab to BEAM and autologous stem cell transplant for relapsed or high-risk chemosensitive DLBCL produces a 3-yr OS of 81% without excess toxicity. This compares favorably to historical controls. This regimen is currently being tested in a phase III trial in the BMT/CTN of Rituximab/BEAM vs. 131-I tositumomab/BEAM in patients with relapsed chemosensitive DLBCL.

Abstract Background Pre-transplant FDG-PET (PET) normalization is the strongest predictor of outcome following autologous stem cell transplant (ASCT) for patients with relapsed or refractory (rel/ref) Hodgkin lymphoma (HL) (Moskowitz, AJ. Blood. 2010 Dec 2;116(23):4934-7). Due to its high efficacy in ASCT failures, we aimed to determine whether brentuximab vedotin (BV) can replace ICE (ifosfamide, carboplatin, etoposide) salvage therapy, increase rate of PET normalization, and enhance referral to ASCT for patients (pts) who fail front-line HL therapy. Here we present our phase II study evaluating a novel salvage strategy for rel/ref HL, an intent-to-treat study of PET-adapted sequential therapy with BV and augmented ICE (augICE) prior to ASCT. Methods Patients with rel/ref HL who have failed 1 prior regimen are enrolling on this phase II clinical trial. Patients receive weekly brentuximab vedotin (BV) administered at 1.2mg/Kg IV weekly for 3 weeks on and 1 week off for 2 cycles, followed by PET. Patients who achieve normalization of PET (Deauville 2 or less) proceed to ASCT. Patients with PET scores of Deauville 3 or higher receive 2 cycles of augICE prior to consideration for ASCT. Results 41 of planned 46 patients have enrolled; 34 pts completed salvage therapy, of whom 33 proceeded to ASCT. 28 pts are at least 90 days post-ASCT and represent the focus of this report. These 28 pts include 20 (71%) males, 21 (75%) pts with primary refractory or relapse within 1 year of initial treatment, 11 (39%) with B symptoms at enrollment and 11 (39%) with extranodal disease. Median number CD34+ cells/kg collected were 7.44x 10^6 (2.96 - 31.43x10^6). Disease status prior to ASCT was CR (Deauville 2) for 27 pts and PR (Deauville 3) for 1 pt. Salvage therapy for pts in CR prior to ASCT include BV alone (9), BV followed by augICE (16), and BV followed by augICE (with Deauville 4 response) followed by involved field radiation to achieve CR (2). The 1 patient in PR prior to ASCT received BV followed by augICE. Conditioning regimens included BEAM (9), CBV( 9), and high dose chemoradiotherapy (10). Early (within 90 days) transplant-related toxicities include grade 2 pneumonitis (3pts) and grade 3 acute kidney injury (1pt); late toxicities include grade 3 esophageal stenosis (1pt), grade 3 acute kidney injury (1pt), and 1 death (7 months post ASCT) due to progressive multifocal leukoencephalopathy. After a median follow-up of 9.5 months post-ASCT (range 3.3-15.6 months), 2 of 28 pts have progressed (at 2.7 and 4.3 months post ASCT respectively). One achieved a second CR with BV and proceeded to allogeneic stem cell transplant (alloSCT); the second achieved near CR following GND (gemcitabine, vinorelbine, Doxil) and proceeded to alloSCT. Conclusion PET-adapted sequential salvage therapy with BV followed by augICE produces high CR rates, adequate stem cell collection, and facilitates referral to ASCT for virtually all pts. Updated results will be presented at the meeting. Disclosures: Moskowitz: Seattle Genetics: Research Funding.

Abstract Introduction: For patients with relapsed or refractory DLBCL with chemosensitive disease after 2nd line (salvage treatment), AutoHCT is considered the standard of care. Risk factors for progression following AutoHCT include primary refractory disease and early relapse (<12 months after initial chemotherapy. In our institution, we have previously shown that a course of ICT given prior to AutoHCT in patients with these high-risk features results in improved outcomes in DLBCL and other lymphomas (Damon et al, BMT 2008; 42(10):649-57). More recently, cell of origin (COO) subtype and double myc and bcl2 protein expression (DPP) status have been shown to predict outcome to front line treatment but data in the relapsed setting are lacking. We hypothesized that our approach of ICT followed by AutoHCT will increase the likelihood of complete remission (especially in patients with high-risk clinical or biologic features) and improve progression free survival (PFS) following AutoHCT. Methods: Consecutive patients who underwent ICT followed by autoHCT for relapsed/refractory DLBCL at our institution between 2005-2015 and had available tissue samples for review were included in our analysis. ICT was applied per institutional standard to patients with apriori identified high-risk features as described below. This chemotherapy step is utilized for stem cell mobilization following evidence of chemosensitivity and prior to undergoing AutoHCT. COO was determined using the Hans algorithm and DPP status using the Johnson criteria. Following CHR approval, patient's charts and EMR were reviewed to ascertain baseline variables and outcome data. Response was determined using radiologic (CT) and metabolic (PET) imaging for all patients at the time of transplantation. Survival probability was estimated by the Kaplan-Meier method. Comparisons were made using the X2 test and Fisher's exact test, where appropriate. Results: A total of 35 patients were included in this analysis. Out of those, 30 patients received a high-dose etoposide and ara-C-based ICT regimen as described by Damon et al. 13/30 (43.3%) were female, 17/30 (56.7%) were male. Median age at transplant was 56 (range 34-68). The high risk features that lead to this treatment were: early (<12 months) relapse (9/30, 30%) or refractory disease (13/30, 43.3%)to front line therapy or other (8/30, 27.7%). In all, 16/30 (53%) patients achieved CR at the end of salvage therapy, with this proportion increasing to 26/30 (86.7%) CR after ICT. Eventually, 24/30 (80%) of patients were able to continue on to AutoHCT, 23/30 (76.7%) with CBV, 4/30 (13.3%) with BEAM, and 3/10 (10.0%) other. With a median follow up of 20 months, 66% of patients are progression-free at 24 months (Figure 1). In our cohort, 8/30 (27%) were germinal center B-cell origin subtype (GCB), 19/30 (63.3%) were non-GCB subtype and 3 (10.0%) could not be identified. In all, 8/30 (26.7%) were double protein positive, 18 (60.0% were double protein negative and 4 (13.3%) could not be determined. Notably, 15.8% of patients with non-GCB were double protein expressors, compared to 37.5% of patients with GCB (Fisher's exact p=0.06). Neither COO nor DPP were associated with response rates prior to AutoHCT (p=0.6 and p=0.17 respectively) or with PFS (p=0.32 and p=0.72 respectively and Figures 2a and 2b). Conclusions: Even though COO and DPP status are associated with inferior outcomes in the front-line setting of patients with DLBCL, data in the relapsed setting are limited. In a cohort of high-risk patients with relapsed DLBCL, we confirmed our previously described excellent outcomes with ICT in terms of increased CR rates prior to AutoHCT and a high rate of 2-year PFS. Moreover, while numbers are small, our study suggests that ICT leads to similar outcomes regardless of cell of origin or double protein expression status.
