Introduction. The combination of rituximab and lenalidomide (R2) is active in patients with untreated indolent lymphoma. Recent randomized trials (RELEVANCE) have demonstrated similar efficacy when compared to standard chemo-immunotherapy backbones. Long term follow up of patients receiving R2 as well as predictors of long term remission and survival have yet to be published. Methods. We prospectively evaluated patients with low grade advanced stage FL who received R2 as initial treatment at our institution between 07/2008 and 10/2014. Lenalidomide was given at 20 mg (day 1-21, in a 28 day cycle) for 6 cycles with rituximab monthly. Lenalidomide starting dose was 10 mg if baseline creatinine clearance was < 60 mL/min. Patients with an objective response continued with 10-20 mg of lenalidomide with rituximab for up to 12 more cycles. Response was evaluated according to 2014 Lugano criteria. Results. One-hundred and one patients were included in the analysis, baseline characteristics are shown in the Table. Median number of provided cycles was 7 (range, 1-20). Median dose of lenalidomide was 20 mg (range, 5-20 mg), and 29 (29%) patients required a dose reduction. Fifty-six (55%) patients experienced grade 3-4 treatment-related toxicities, the most common (> 5%) being neutropenia (39%), skin rash (20%), myalgia (16%) and fatigue (16%). Seven (7%) patients discontinued treatment before completion, after a median time of 4 months (range, 1-10 months): 4 because of toxicity (arterial thrombosis in 2, respiratory failure in 1, and skin rash in 1), and 3 because of progression. Ninety-eight patients were evaluable for response, while 3 patients discontinued treatment because of toxicity before first response assessment. Overall response rate was 98%, CR rate 90% (both achieved after a median of 6 months [range, 3-22 months]), and CR rate at 30 months (CR30) was 80%. Only female sex associated with a higher CR rate (96% vs 83%, p=0.05), while no baseline characteristic associated with CR30 rate. After a median follow-up of 88 months (95% confidence interval, 84-92 months), 31 (31%) patients progressed and/or died, 7-year progression-free survival (PFS) was 63%, and 13% of patients had a PFS < 24 months (PFS24). Failure to achieve CR was the only factor associated with significantly decreased PFS (10 months vs not reached, p<0.001) and higher likelihood of PFS24 (46% vs 5%, p<0.001). No association was observed with baseline characteristics, including FLIPI and FLIPI-2 score. At most recent follow-up, transformation was reported in 3 (3%) patients, after 30, 32 and 42 months, respectively. Two (2%) patients have died, 1 of unrelated comorbid health conditions, 1 of progressive disease, and 7-year overall survival was 98%. Second cancers (excluding transformation) were diagnosed in 8 (8%) patients, after a median of 55 months (range, 3-105 months). These included: breast adenocarcinoma (2), melanoma (2), pancreatic adenocarcinoma (1), esophageal adenocarcinoma (1), and therapy-related acute myeloid leukemia. Discussion. Long-term follow-up show very favorable outcomes for patients with advanced stage FL receiving R2 as initial treatment, independent of traditional prognostic factors relevant to patients treated with chemoimmunotherapy, including FLIPI and FLIPI-2 score. Combination strategies, aimed at increasing depth of response to R2, may further improve outcomes observed with this regimen. Table.

Introduction: The R-MegaCHOEP trial showed that dose-escalation of conventional chemotherapy necessitating autologous stem cell transplantation (ASCT) does not confer a survival benefit for younger patients (pts) with high-risk aggressive B-cell lymphoma in the Rituximab era (Schmitz et al., Lancet Oncology 2012; 13, 1250-1259). To describe efficacy and toxicity over time and document the long-term risks of relapse and secondary malignancy we present the 10-year follow-up of this study. Methods: In the randomized, prospective phase 3 trial R-MegaCHOEP younger pts aged 18-60 years with newly diagnosed, high-risk (aaIPI 2-3) aggressive B-cell lymphoma were assigned to 8 cycles of CHOEP (cyclophosphamide, doxorubcine, vincristine, etoposide, prednisone) or 4 cycles of dose-escalated high-dose therapy (HDT) necessitating repetitive ASCT both combined with Rituximab. Both arms were stratified according to aaIPI, bulky disease, and center. Primary endpoint was event-free survival (EFS). All analyses were calculated for the intention-to-treat population. This follow-up report includes molecular data based on immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) for MYC (IHC: 31/92 positive [40-100%], FISH: 14/103 positive), BCL2 (IHC: 65/89 positive [50-100%], FISH: 23/111 positive) and BCL6 (IHC: 52/86 positive [30-100%], FISH: 34/110 positive) and data on cell of origin (COO) classification according to the Lymph2CX assay (GCB: 53/88; ABC: 24/88; unclassified: 11/88). Results: 130 pts had been assigned to R-CHOEP and 132 to R-MegaCHOEP. DLBCL was the most common lymphoma subtype (~80%). 73% of pts scored an aaIPI of 2 and 27% an aaIPI of 3. 60% of pts had an initial lymphoma bulk and in 40% more than 1 extranodal site was involved. After a median observation time of 111 months, EFS at 10 years was 57% (95% CI 47-67%) in the R-CHOEP vs. 51% in the R-MegaCHOEP arm (42-61%) (hazard ratio 1.3, 95% CI 0.9-1.8, p=0.228), overall survival (OS) after 10 years was 72% (63-81%) vs. 66% (57-76%) respectively (p=0.249). With regard to molecular characterization, we were unable to detect a significant benefit for HDT/ASCT in any subgroup analyzed. In total, 16% of pts (30 pts) relapsed after having achieved a complete remission (CR). 23% of all relapses (7 pts) showed an indolent histology (follicular lymphoma grade 1-3a) and 6 of these pts survived long-term. In contrast, of 23 pts (77%) relapsing with aggressive DLBCL or unknown histology 18 pts died due to lymphoma or related therapy. The majority of relapses occurred during the first 3 years after randomization (median time: 22 months) while after 5 years we detected relapses only in 5 pts (3% of all 190 pts prior CR). 11% of pts were initially progressive (28 pts) among whom 71% (20 pts) died rapidly due to lymphoma. Interestingly, the remaining 29% (8 pts) showed a long-term survival after salvage therapy (+/- ASCT); only 1 pt received allogeneic transplantation. The frequency of secondary malignancies was very similar in both treatment arms (9% vs. 8%) despite the very high dose of etoposide (total 4g/m2)in the R-MegaCHOEP arm. We observed 2 cases of AML and 1 case of MDS per arm. In total 70 pts (28%) have died: 30 pts due to lymphoma (12%), 22 pts therapy-related (11 pts due to salvage therapy) (9%), 8 pts of secondary neoplasia (3%), 5 pts due to concomitant disease (2%) and 5 pts for unknown reasons. Conclusions: This 10-year long-term follow-up of the R-MegaCHOEP trial confirms the very encouraging outcome of young high-risk pts following conventional chemotherapy with R-CHOEP. High-dose therapy did not improve outcome in any subgroup analysis including molecular high-risk groups. Relapse rate was generally low. Pts with aggressive relapse showed a very poor long-term outcome while pts with indolent histology at relapse survived long-term. Secondary malignancies occurred; however, they were rare with no excess leukemias/MDS following treatment with very high doses of etoposide and other cytotoxic agents.

Purpose: Hodgkin's lymphoma (HL) is a highly curable disease even in advanced-stage, with >90% of long-term survivors. Currently, the standard of care is ABVD (doxorubicin, etoposide, vinblastine and dacarbazine), as it is less toxic and as effective as other more intensive chemotherapy regimens. Alternatively, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) has been proposed as front-line intensified regimen with a better initial disease control and prolonged time to relapse when compared to ABVD. However, this advantage is associated with higher rates of severe hematologic toxicity, treatment-related deaths, secondary neoplasms and infertility. To date, the debate regarding which regimen should be preferred as first line for advanced-stage HL is still ongoing. To shed some light on this open question we compared efficacy and safety of both regimens in clinical practice. Patients and Methods: From October 2009 to October 2018, patients with HL stage III-IV treated with either ABVD or BEACOPP escalated (BEACOPPesc) were retrospectively assessed in 7 European cancer centers. Results: A total of 372 consecutive patients were included in the study. One-hundred and ten patients were treated with BEACOPPesc and 262 with ABVD. The baseline characteristics of the two groups did not differ significantly, except for a higher rate of high-risk patients in the BEACOPPesc group in contrast to the ABVD one (47% vs 18%; p= 0.003). Complete response rate (CR) assessed by PET imaging at the end of the second cycle was 67% and 78% for the ABVD and BEACOPPesc group (p= 0.003), respectively. Thirteen patients of the ABVD group achieved stable disease (SD) and 6 had a progression disease (PD). On the other hand, 4 of the patients in the BEACOPPesc group progressed, another 2 interrupted therapy because life-threatening toxicity. At the end of the therapy, CR was 76% in the ABVD group and 85% in the BEACOPPesc group (p= 0.01). A total of 20% patients in the ABVD group and 14% patients in the BEACOPPesc group received consolidation radiotherapy on the mediastinal mass at the dose of 30Gy. After radiotherapy, the number of patients with CR increased to 79% and 87% in the two groups (p= 0.041), respectively. Thirty-nine patients (35%) in the BEACOPPesc group required dose reduction of chemotherapy due to toxicity compared to 12 patients (5%; p= <0.001) in the ABVD group. Overall, the rate of severe toxicities was higher in the BEACOPPesc group in comparison with the ABVD cohort. In particular, there was a significant increased frequency of acute grade 3-4 hematologic adverse events (neutropenia 61% vs 24%; anemia 29% vs 4%; thrombocytopenia 29% vs 3%), febrile neutropenia (29% vs 3%), severe infections (18% vs 3%). Myeloid growth factors were administered to 85% and 59% of patients in the BEACOPPesc group compared to the ABVD group. Blood transfusions were required in 51% and 6% of patients in the BEACOPPesc group compared to the ABVD cohort. Progression during or shortly after treatment occurred in 5 patients in the BEACOPPesc group (4%) and in 16 patients in the ABVD group (6%; p= 0.62). Among the 96 patients who achieved a CR after BEACOPPesc and radiotherapy, 8 relapsed (8%), compared to 29 of 208 patients in the ABVD group (14%; p= 0.04). At a median follow-up period of 5 years, no statistical difference in progression free survival (PFS; p=0.11) and event-free survival (EFS; p=0.22) was observed between the BEACOPPesc and ABVD cohorts. Similarly, overall survival (OS) did not differ between the two groups (p=0.14). The baseline international prognostic score (IPS <3 vs ≥ 3) significantly influenced the EFS with an advantage for the high-risk group treated with BEACOPPesc (Figure 1A; p=0.03), but not the PFS (Figure 1B; p=0.06) and OS (Figure 1C; p=0.14). During the follow-up period, in the BEACOPPesc group one patient developed myelodysplasia and one acute leukemia. Second solid tumors developed in one patient in the ABVD group (lung cancer) and one in BEACOPPesc group (breast cancer). Conclusion: We confirm that the ABVD regimen is an effective and less toxic therapeutic option for advanced-stage HL. Although BEACOPP results in better initial tumor control especially in high-risk patients, the long-term outcome remains similar between the two regimens.

Abstract Abstract 3697 Introduction: Rituximab has been a useful treatment for patients with ITP; many hundreds of patients have been treated. 30–40% of patients will achieve a complete remission (CR: platelet count >150 × 109/l) with initial treatment and, of this group, the CR will last at least a year in almost all patients. However, emerging data suggests that at least 40% of these patients in CR will relapse between 1 and 3 years from initial treatment suggesting that long-term “cures” only occur in 20% of the initial patients. Therefore it would be desirable if CR's could be achieved in more patients and especially if these would be durable in more than 20%. One approach would be to use rituximab maintenance, however it results in suppression of B-cells for more than 2 years. Dexamethasone has also been used to achieve “cure” in ITP especially in adults at or near diagnosis. Cheng's study suggested that approximately 50% of patients would achieve a long-term response with only one 4-day cycle of high dose (40 mg/day) dexamethasone (N Engl J Med, 2003). A follow up study from GIMEMA suggested that 3–4 cycles of dexamethasone would be better than 1 cycle (Blood, 2007). Finally, Zaja's study suggested that rituximab plus one cycle of dexamethasone was superior to dexamethasone alone with a > 50% CR rate at 6 months (Blood, 2010). Therefore, we elected to perform a pilot study to explore the combination of rituximab with three cycles of dexamethasone at 14 day intervals. Methods: Patients with ITP with platelet counts < 30,000 off therapy and in need of treatment were enrolled. The standard dose (4 infusions of 375mg/m2) rituximab was given on days 1, 8, 15 and 22 and dexamethasone 40 mg (adjusted for size) on days 1–4, 15–18, and 29–32. Results: Fourteen patients between the ages of 4 and 53 years with ITP were treated with rituximab and dexamethasone (R&D) (Table 1). All had received previous steroid therapy as well as other treatments. The median platelet count was 40,000 at initiation of rituximab (range 7,000-230,000); several patients with low counts started with dexamethasone prior to initiating Rituximab to sustain their counts during initial treatment. Patients received rituximab weekly for between 2 and 4 doses and dexamethasone for either 2 or 3 courses at intervals between 1 and 8 weeks (median 2 week intervals). A summary of the results is shown in table 2 demonstrating short-lived platelet increases in response to dexamethasone in almost all patients. With short follow up, there were 7 CR's, 3 PR's and 4 NR's. If this was divided by duration of ITP prior to R&D, there were 4 CR's and 1 NR for ≤ 12 months and 3 CR, 3 PR, and 3 NR for > 12 months. More of the children who were treated had chronic disease than did adults explaining their apparently poorer response. Observed toxicities included hyperglycemia, grade 1 and 2 liver function abnormalities, weight gain, and 1 episode of colitis requiring hospitalization. Three patients opted to skip the third cycle of dexamethasone. Conclusion: A regimen of rituximab + 2–3 courses of dexamethasone is active in patients with pretreated ITP with appreciable but usually manageable toxicity. It appears to yield superior results if administered to patients within one year of diagnosis. This combination merits further exploration in a prospective clinical trial.

Abstract INTRODUCTION The hypomethylating agents (HMAs), decitabine (DEC) and azacitidine (AZA), have made it possible to treat more elderly patients with acute myeloid leukemia (AML). Both HMAs have demonstrated efficacy in monotherapy and in combination with targeted therapies. However, there is little direct comparative data on AZA and DEC in first-line treatment, and we do not know which group of patients might benefit from each drug. Results of the full analysis set (FAS) were presented previously (Labrador J, et al. ASH 2020). Here, we report long-term clinical efficacy from prespecified patient subgroup analyses. METHODS We conducted a retrospective study to compare real-life clinical outcomes between AZA and DEC in patients with AML ineligible for intensive chemotherapy included in the PETHEMA registry, and analyzed clinical variables associated with response and overall survival (OS) between AZA and DEC. RESULTS A total of 626 patients were included for the FAS between 2006 and 2019. 487 (78%) received AZA and 139 (22%) received DEC. Baseline characteristics were comparable in both groups, except for the percentage of bone marrow blasts (44% vs. 34% in the DEC group compared to AZA, p=0.010). In the FAS, there was no difference in the CR, CR/CRi or ORR (CR/RCi + PR) rate: 18%, 20.5% and 32% with AZA vs. 23%, 25% and 39.5% with DEC (p=0.20, p=0.27 and p=0.12). In the subgroup analysis, DEC was associated with higher CR/CRi rate than AZA in patients with ECOG ≥ 2 (95% CI: 0.088 - 0.801), bone marrow blast count &lt; 50% (95% CI: 0.293 - 0.965), secondary AML (95% CI: 0.223 - 0.918) and adverse cytogenetics (95% CI: 0.171 - 0.857) (Figure 1A). DEC was associated with higher ORR rate than AZA in patients with ECOG ≥ 2 (95% CI: 0.116 - 0.782), leukocytes &lt; 10 x10 9/L (95% CI: 0.321 - 0.920) and bone marrow blasts &lt; 50% (95% CI: 0.321 - 0.920) (Figure 1B) 120 days-mortality was 25.4% after AZA and 27.1% after DEC, p=0.70. Patients who did not achieve at least a PR had significantly higher 120-day mortality with both HMAs (OR 8.85 and 8.22 for AZA and DEC, respectively). In the subgroup analysis, patients with leukocytes ≥ 10 x10 9/L (95% CI: 1.069 - 4.157) and those with estimated glomerular filtration rate (eGFR) ≥ 45 mL/min/1.73m 2 (95% CI: 1.249 - 4.664) had higher 120-day mortality with DEC than with AZA (Figure 1C) With a median follow-up of 12 months, median OS was 10.4 months (95% CI: 9.2 - 11.7) for AZA vs. 8.8 months (95% CI: 6.7 - 11.0) for DEC (p = 0.455). The subgroup analysis revealed that patients ≥ 80 years (95%: CI 1.005 - 2.341), with leukocytes ≥ 10 x10 9/L (95% CI 1.039 - 2.062), platelet count &lt;20 x10 9/L (95% CI: 1.150 - 3.422) and those with eGFR ≥ 45 mL/min/1.73m 2 (95% CI: 1.040 - 2.059) did benefit for treatment with AZA compared to DEC (Figure 1D). CONCLUSIONS Our study provides real-life data on the outcomes of AML patients treated with AZA compared to DEC in a large retrospective cohort with long-term follow-up. In addition, we identify for the first time some baseline characteristics that could benefit from AZA or DEC in terms of responses, 120-day mortality and OS. These findings could help us to choose the most appropriate HMA in monotherapy or for the development of new combinations. Figure 1 Figure 1.

Introduction: Tandem autologous transplant (auto- auto) has been studied as a method to increase remission rates and reduce relapse in the upfront therapy of MM. The use of autologous followed by reduced intensity conditioning allogenic transplantation (auto-allo) offers the potential of long-term graft-versus-myeloma (GVM) effect, but with the risk of graft versus host disease and potentially higher non-relapse mortality (NRM). Trials comparing these two strategies relied on availability of HLA-matched sibling donors for arm allocation (biological "randomization") and have yielded conflicting results, in part due to trial size or limited follow up. A pooled analysis of multiple trials with extended follow up provides the best opportunity to compare these two transplant strategies. Methods: We obtained individual patient data from participants of 4 trials comparing auto-auto vs. auto-allo after brief induction therapy, namely BMT CTN 0102 (N=709), NMAM2000 (N=357), PETHEMA/GEM2000 (N=110), and the Torino consortium trial (N=162). In all 4 trials arm allocation was by biological "randomization". Patients were designated high risk if beta-2 microglobulin ≥ 4.0 mg/L at diagnosis or presence of deletion of chromosome 13 by metaphase karyotyping. Time to event outcomes were analyzed by intention to treat, from the time of first autologous transplant. Main outcomes analyzed were overall survival (OS) and progression free survival (PFS). Secondary outcomes analyzed were NRM and risk of relapse, treated as competing risks, and post relapse survival. Results: There were 1,338 patients included in the analysis, 899 in auto-auto and 439 in auto-allo. Median follow up of survivors is 118.5 months. Characteristics of the two arms are displayed in Table 1. Median OS was 78.0 months in auto-auto and 98.3 months in auto-allo (HR= 0.85, P=0.003, Figure 1). OS was 59.8 % vs. 62.3% at 5-years (P=0.37) and 36.4% vs. 44.1% at 10 years (P=0.01) for auto-auto and auto-allo respectively. PFS was also improved in auto-allo (HR= 0.84, P=0.004) with 5-year PFS of 23.4 vs. 30.1% (P=0.01) and 10-year PFS of 14.4% vs. 18.7% (P=0.06). For the 214 high risk patients (125 auto-auto, 89 auto-allo) there was superior 5-year and 10-year PFS with auto-allo, but no difference in OS. Risk of NRM was higher in auto-allo (10 year 8.3% vs. 19.7%, P&lt;0.001), while risk of disease progression was higher in auto-auto (10 year 77.2% vs. 61.6%, P&lt;0.001). There were 685 progressions in auto-auto and 266 in auto-allo. Median post relapse overall survival was 41.5 months in auto-auto and 62.3 months in auto-allo (HR= 0.71, P&lt;0.001, Figure 2). Five years post relapse, 37.0% of patients were alive in auto-auto vs. 51.1% in auto-allo (P&lt;0.001). Conclusion: Long-term follow up using a large pooled dataset of 4 trials indicates durable, long-term disease control with an auto-allo strategy. Despite higher NRM, there was a reduction in the risk of relapse and superior post relapse survival in auto-allo. This supports the hypothesis of a durable GVM effect enhancing myeloma control with subsequent therapies.

High Doses

Background: Disease relapse following allogeneic stem-cell transplantation remains unacceptably high and there is an urgent need for new therapies that decrease relapse rates and improve survival post-transplant. Natural killer (NK) cells have potent antitumor effects, particularly those expended with mb-IL21 from peripheral blood. Preliminary data from a phase-1 dose-escalation study of up to 1x108 NK cells/Kg/dose and multiple dosing yielded promising results and a favorable safety profile (Ciurea SO.Blood.2017;130:18657). This report presents long-term follow-up from a phase-1/2 clinical trial in patients with high-risk myeloid malignancies (AML/MDS/CML) (clinicaltrials.gov NCT01904136) and a comparison with CIBMTR controls. Methods: Patients received conditioning with fludarabine 160 mg/m2, melphalan 140 mg/m2 and 2GyTBI, post-transplant cyclophosphamide-based GVHD prophylaxis and bone marrow graft from a haploidentical donor. Ex vivo expanded NK cells were generated from peripheral blood mononuclear cells of the same donor with a K562 feeder cells expressing mb-IL21 and 41BB and infused fresh on Day-2, and cryopreserved on Day+7 and +28 (up to Day+90). 1x108/Kg/dose was chosen for the phase 2 trial. An independent matched-pair analysis was done using controls from the CIBMTR database stratified by conditioning intensity. Results: 24/26 patients treated to date were evaluable (one short follow-up and one excluded as ineligible). 80% (19/24) of patients received all 3 doses of NK cells. The median age was 45 years (range 18-59), median follow-up was 43.6 months (range 15.1-60.9). Thirteen patients (54%) were females. 5 patients had donor-specific anti-HLA antibodies (DSA). The median HCT-CI was 2 (range 0-8), 12 patients (50%) had HCT-CI&gt;3. 17 patients (72%) had AML/MDS and 7 (28%) advanced CML. Of AML/MDS patients, 10 (59%) had high-risk cytogenetics, 7 (41%) had measurable residual disease, 9 (53%) had intermediate/adverse-risk ELN2017 and 5 (29.4%) had primary induction failure. No infusion reactions or significant adverse events were observed to date. All patients (100%) achieved engraftment after a median of 19 days (range 14-42). The cumulative incidence (CI) of grade 2-4 aGVHD was 29.2% at Day100 and 41.7% at 1-year post-transplant. Only one patient developed severe grade 3-4 aGVHD and one patient had extensive cGVHD. Only one patient relapsed (a patient with DSA who did not receive desensitization prior to transplantation), 1-year CI of relapse was 5.9%. The CI of TRM at 1-year for patients without DSA was 21%. The median overall survival and progression-free survival (PFS) were not reached. The 1-year and 3-year PFS for all patients and patients without DSA was 70.8% and 66.1%, and 79% and 72.9% for patients without DSA, respectively (Figure 1). One-year and 3-years GRFS for all patients and patients without DSA was 70.8% and 66.1%, and 79% and 72.9%, respectively. An independent matched-pair analysis (at least 1:1) was conducted by CIBMTR after the first 18 patients treated on study in 07/2018 with RIC (N=57) or MAC (N=61) controls. The relapse was 1/18 vs 25/57 for RIC (p=0.037) and 15/61 for MAC (p=0.07), while the 1-year PFS was 82% vs 49% for RIC and 64% for MAC (p=0.21) (Figure 1). Updated results of this analysis will be presented at the meeting. Conclusions: Results from this long-term follow-up analysis confirm very low relapse rate and excellent GRFS after haploSCT for patients treated with high-doses of NK cells expanded with mbIL21 stimulation. A prospective multi-center phase 2 BMTCTN study will evaluate the safetly and efficacy of high doses of NK cells for the prevention of relapse in patents with AML/MDS receiving haploSCT.

Abstract Background Thrombocytopenia in myelodysplastic syndrome (MDS) occurs in approximately 50% of patients with low/intermediate-1 MDS and is associated with reduced survival; few therapies are available. In a randomized placebo-controlled study, 250 patients with MDS were randomized 2:1 to receive weekly romiplostim or placebo. In the original June 2011 analysis, romiplostim reduced clinically significant bleeding events (HR 0.83, 95% CI: 0.66, 1.05, P = 0.13) and platelet transfusions (RR 0.77, 95% CI: 0.66, 0.88), and increased IWG HI-P incidence (OR 15.6, 95% CI: 4.7, 51.8). Increases in peripheral blast counts to >10% were more frequent with romiplostim (25/167, 15%) than placebo (3/83, 3.6%), and in most cases resolved after discontinuation. Due to concerns of the data monitoring committee that the potential benefit seen in the reduction of bleeding did not outweigh the potential risk for disease progression to acute myeloid leukemia (AML) and that transient increases in blast cell counts might put patients at risk for diagnosis of and treatment for AML, treatment with study drug was discontinued in February 2011. Patients were then moved into the long-term follow-up (LTFU) portion of the study. Previously reported (July 2012) 58-week incidence of AML was romiplostim: 6.0% (10 patients), placebo: 4.9% (4 patients), HR 1.20 (95% CI: 0.38, 3.84). This report provides data on long-term follow-up of these patients to March 2013, with a particular emphasis on AML incidence. Methods Eligible patients had IPSS low/intermediate-1 MDS and platelets 1) ≤20x109/L or 2) ≤50x109/L with a history of bleeding, and were receiving only supportive care. Disease progression to AML was defined as 1) ≥20% blasts in the bone marrow or peripheral blood after 4 weeks following discontinuation of romiplostim, 2) pathology consistent with leukemia including chloroma or leukemia cutis, or 3) anti-leukemic treatment initiation. Results are presented by treatment group. Results Of 250 patients in the study, 210 entered LTFU, and 98 of these patients remained on study as of March 2013; the median (Q1, Q3) follow-up was 25.5 (10.8, 33.1) months. Reasons for discontinuation during LTFU were similar in the romiplostim and placebo groups: death (46.7%, 98 patients); lost to follow up (4.8%, 10 patients), and consent withdrawal (1.9%, 4 patients). During the active study period or during LTFU, death was reported in 44.3% (74 patients) in the romiplostim group and 44.6% (37 patients) in the placebo group (HR 1.04, 95% CI: 0.70, 1.54) (Figure). AML was reported in 10.7% (18 patients) in the romiplostim group and 9.8% (8 patients) in the placebo group (HR 1.14, 95% CI: 0.49, 2.62) (Figure). The proportions of patients who either died or developed AML were 46.1% (77 patients) in the romiplostim group and 45.8% (38 patients) in the placebo group (HR 1.07, 95% CI: 0.72, 1.58). Thirteen of the 26 AML cases occurred in patients who were RAEB-1 and 5 cases were diagnosed by anti-AML treatment alone (Table). In LTFU, patient-reported use of MDS therapy (e.g., azacitidine or cyclosporine) in the romiplostim group was 40.6% and in the placebo group, 28.2%. Reported use of AML therapy (e.g., chemotherapy) was 8.8%, romiplostim and 7.0%, placebo. Conclusion Following the 2011 decision to stop study drug, results have been updated with more observational time on study. Specifically, the HRs for death or progression to AML are 1.04 and 1.14, respectively, compared with 2012 HRs of 1.09 (95% CI: 0.71, 1.68) and 1.15 (95% CI: 0.47, 2.85) respectively. In LTFU, more patients in the romiplostim group than in the placebo group received MDS therapy. As LTFU continues, additional data will be evaluated. Safety concerns regarding risk of disease progression to AML are still being investigated. Disclosures: Kantarjian: Amgen Inc.: Research Funding.

Abstract Background: We reported better PFS and OS in transplant eligible patients with newly diagnosed Multiple Myeloma (MM) who were treated with bortezomib during induction and maintenance, when compared with standard treatment in the HOVON-65/GMMG-HD4 trial. (P. Sonneveld et al., J Clin Oncol 30:2946-2955, 2012). Here the long-term follow up data are presented. Methods: 827 eligible patients were randomized to induction therapy with VAD (vincristine, doxorubicin, dexamethasone) or PAD (bortezomib, doxorubicin, dexamethasone) followed by high-dose melphalan (once or twice) and autologous stem cell transplant. Maintenance consisted of daily thalidomide (T) 50 mg (VAD arm) or 2-weekly bortezomib (B) 1.3 mg/m2 (PAD arm) for 2 years. The primary endpoint was progression-free survival (PFS) adjusted for ISS stage. Results: After a median follow up of 91.4 months (maximum 119) 410 patients are alive. Response rates were VAD/HDM/T: CR 25%, ≥VGPR 56%, ≥PR 83%; PAD/HDM/B: CR 37%, ≥VGPR 76%%, ≥PR 91%, The median duration of maintenance therapy was 14 months (thalidomide) and 23 months (bortezomib), respectively. Main reasons for discontinuation were toxicity (T: 31%; B: 11%), disease progression (T: 33%; B: 36%) or normal completion (T: 28%; B: 48%). Of 827 patients in the analysis, 206 are alive without progression/relapse. PFS was significantly better in the bortezomib arm, i.e. median 34 versus 28 months (HR=0.77, 95% CI=0.65-0.90, p=0.001). Median overall survival (OS) was 90 months in the bortezomib arm vs 83 months in the control arm, but 42% at 9 years in both arms. We used the restricted mean survival time (RMST) method to compare OS between the two treatment arms In univariate analysis. The difference in RMST8y was 4.8 months (95% CI 0.2-9.5, p=0.04) in favor of the bortezomib arm. A landmark analysis in patients who had received HDM starting at 12 months showed a significant PFS advantage of bortezomib in all patients (p=0.02), in patients in VGPR/PR (p=0.02) but not in CR (p=0.19). For OS there was no advantage for bortezomib in either group. PFS at 60 months in bortezomib treated patients was not different when single vs double HDM/ASCT was administered, i.e. 28% vs 27%. However, OS at 60 months was 71% vs 60% in favor of double HDM/ASCT (p=0.04). Subgroup analysis was performed based on presence/absence of adverse FISH (CA) in 395 patients treated with double HDM/ASCT. PFS at 60 months for each abnormality (CA or no CA) in bortezomib vs standard arm is given in Table 1 Table 1.PFS at 60 months, %OS at 60 months, %FISHnBortezomib armpStandard armBortezomib armpStandard Armt(4;14) yes/no50/29516% vs 27%0.048% vs 24%52% vs 75%0.0133% vs 64%add(1q) yes/no113/23116% vs 32%0.00510% vs 28%57% vs 79%0.00143% vs 70%del(17p) yes/no39/31222% vs 27%0.475% vs 24%65% vs 72%0.4818% vs 66% These data show that bortezomib treatment combined with double HDM/ASCT significantly improves PFS and OS in patients with del(17p) and almost abrogates the negative impact of this CA. In t(4;14) and add(1q) some improvement is observed, however the negative impact remains significant. In high-risk patients presenting with elevated creatinine >2 mg/dL bortezomib significantly improved PFS at 60 months (32% vs 5%) (p=0.001) and OS at 60 months (66% vs 21% months (p<0.001)). OS at 8 years was 46% vs 12%. Finally, OS from progression/relapse was not different between patients treated in the bortezomib vs standard arm (OS at 72 months: 33% vs 35%, p=0.73) Conclusions: We conclude that bortezomib leads to a significant and lasting improvement of PFS and OS. Bortezomib significantly reduces the high-risk impact of del(17p) and renal impairment on survival.

Abstract Introduction: Post autologous transplant maintenance therapy with lenalidomide for patients with multiple myeloma (MM) is standard of care (McCarthy et al, NEJM, 2012). Vorinostat (SAHA, Zolinza) is a HDAC inhibitor and preclinical data suggested that HDAC-I's increase MHC class I and class II expression, rendering tumor cells more susceptible to host innate immune killing. Lenalidomide activates NK cells via PP2A inhibition and induces CD56 expression in CD16+CD56- cells thereby enhancing NK cell-mediated ADCC. Initiating lenalidomide to enhance NK cell activity against tumor cells in the early post autologous transplant period may be particularly effective when the NK:myeloma cell ratios favor NK killing, especially if administered after increased MHC class I expression induced by HDAC-I pretreatment. We hypothesized that the combination of vorinostat and lenalidomide would be both tolerable and effective in the post-transplant setting. We have published the initial report of this combination (Sborov, BJH, 2015). We now present the long term follow up. Methods: This was a non-randomized, open-label phase I trial for patients with myeloma who have received high dose IV melphalan followed by autologous peripheral blood stem cell transplant (ASCT) following the three-and-three up-and-down phase I design. Vorinostat was administered beginning at 200 mg starting day +90 after HSCT for days 1-7 and 15-21 of a 28-day cycle combined with lenalidomide 10 mg days 1-21 of a 28-day cycle until progression or clinically significant toxicity. The initial dose of lenalidomide could be increased from 10 mg after cycle 1 and escalated as tolerated up to 25 mg. Results: Sixteen patients were enrolled after autologous transplant with a median age 58 y.o. (range 41-67), with a median number of prior therapies at enrollment of 2 (range 1-8) and mean ISS stage 1.5 (range 1-3). Twelve patients had trisomies on CD138-selected FISH, one patient had normal cytogenetics, and three patients had high risk features [complicated karyotype, t(4;14), or abnormal chromosome 1]. All patients started with 10 mg of lenalidomide and 14 patients received more than one cycle of therapy. 11/14 (78%) were able to escalate the lenalidomide dose. 4/11 (36%) were able to escalate to 25 mg of lenalidomide. The tolerability, toxicities and adverse events have been previously reported (Sborov, BJH, 2015). With a median follow up of 84 months (range 17 - 88), 9 patients (56%) have progressed and 5(31%) have died due to disease progression. Seven patients (44%) remain in complete remission with 5 currently on continued maintenance more than 72 months from ASCT. The median progression-free survival (PFS) is 46.5 months (range 2 - 88) and the median overall survival (OS) has not been reached (17 to NR) (Figure 1). Conclusions: The combination of lenalidomide and vorinostat is well tolerated, with prolonged PFS and OS. Details on the current seven patients still in remission and on continued maintenance will be presented at the meeting.

Background LentiGlobin gene therapy contains autologous CD34+ hematopoietic stem cells (HSCs) transduced with the BB305 lentiviral vector (LVV), encoding human β-globin with a T87Q substitution. This substitution confers anti-sickling properties to the gene therapy-derived hemoglobin (HbAT87Q) and allows for its quantification in transduced HSCs. The proof of concept for LentiGlobin gene therapy in patients with transfusion-dependent β-thalassemia (TDT) and sickle cell disease (SCD) was established in the recently completed HGB-205 study (NCT02151526). Herein, we provide the safety and efficacy outcomes and long-term follow-up data for all 7 treated patients, 4 with TDT and 3 with SCD. Methods Patients 5−35 years old with TDT (≥ 100 mL/kg of packed red blood cells [pRBCs]/year) or severe SCD (e.g., ≥ 2 acute chest syndromes [ACS] or ≥ 2 vaso-occlusive crises in the preceding year or the year before regular transfusions) were enrolled. CD34+ HSCs were obtained by mobilization and apheresis in patients with TDT or by bone marrow harvest in patients with SCD. Following collection, cells were transduced with the BB305 LVV. Patients underwent busulfan myeloablative conditioning and were infused with transduced cells. Patients were monitored for engraftment, adverse events (AEs), HbAT87Q levels, and other hematologic and clinical parameters. After 2 years in HGB-205, patients transitioned into the long-term follow-up study, LTF-303 (NCT02633943). Summary statistics are shown as median (min-max). Results As of June 2019, patients with TDT (n=4) and SCD (n=3) had a median follow-up of 49.6 (40.5-60.6) and 28.5 (25.5-52.5) months, respectively. Table 1 shows patient and drug product characteristics and several key efficacy outcomes. All patients achieved HSC engraftment. LentiGlobin safety profile was consistent with busulfan myeloablative conditioning and, in case of SCD, with the underlying disease state. The most common non-hematologic Grade ≥ 3 AEs post-LentiGlobin gene therapy (≥ 2 patients) for patients with TDT were stomatitis (n=4) and increased aspartate aminotransferase (n=2), and for patients with SCD were ACS (n=2) and vaso-occlusive pain (n=2). In all 4 patients with TDT, total Hb and HbAT87Q levels remained generally stable up to 5 years post-LentiGlobin infusion. Three of 4 patients achieved transfusion independence (TI; defined as weighted average Hb ≥ 9g/dL without pRBC transfusions for ≥ 12 months), for an ongoing duration of 56.3 (38.2-57.6) months. Weighted average total Hb during TI was 11.4 (10.5-13.0) g/dL. One patient has been off transfusions for 37.5 months and had total Hb of 7.7 g/dL, which was below the ≥ 9 g/dL requirement to meet the protocol definition of TI. At last visit, HbAT87Q levels in these 4 patients ranged from 6.2-11.2 g/dL, which contributed 73.8-86.8% of the total Hb. The first patient treated with LentiGlobin for SCD experienced one vaso-occlusive pain episode, which developed at 30 months after LentiGlobin gene therapy following a case of acute gastroenteritis with fever and dehydration. The second SCD patient had 2 serious AEs (SAEs) of ACS approximately 6 and 8 months after LentiGlobin gene therapy. The patient resumed chronic pRBC transfusions and hydroxyurea treatment and subsequently experienced 2 SAEs of vaso-occlusive pain; no additional SAEs of vaso-occlusive pain or ACS were reported during the last 16 months of follow-up after LentiGlobin infusion. The third SCD patient had no episodes of vaso-occlusive pain or ACS during 25.5 months of follow-up post-LentiGlobin gene therapy as of the data cut-off. Two patients with SCD who have been off chronic pRBC transfusions, showed improvement in hemolysis markers post-LentiGlobin treatment and stabilization of HbAT87Q expression at approximately 6 months post-LentiGlobin infusion. Total Hb levels for patients with SCD at last visit were 13.0 g/dL (patient 1), 9.4 g/dL (patient 2), and 9.8 g/dL (patient 3), with corresponding HbAT87Q contributions of 47.9%, 7.9%, and 25.8%, respectively. Summary With up to 5 years of follow-up, treatment with LentiGlobin gene therapy was well tolerated and resulted in improvement in hematologic parameters and disease-related symptoms. Further results from the completed study will be presented.
