We assessed long-term safety and efficacy of CT-P10 and rituximab in patients with newly diagnosed low-tumour-burden follicular lymphoma (LTBFL), and following a single transition from rituximab to CT-P10. This double-blind, parallel-group, active-controlled phase 3 trial randomized patients with CD20+ LTBFL to receive CT-P10 or US-sourced rituximab (375 mg/m2 intravenous). Induction therapy (weekly for 4 cycles) was followed by a 2-year maintenance period for patients achieving disease control (CR, CRu, PR and SD). During the maintenance, CT-P10 or rituximab were administered every 8 weeks (6 cycles) in the first year and additional CT-P10 was administered every 8 weeks (6 cycles) in the second year. Secondary endpoints (reported here) were overall response rate during the study period, progression-free survival, time-to-progression, and overall survival. Safety and immunogenicity were also evaluated over the study period. Between Nov 9, 2015 and Jan 4, 2018, 258 patients were randomised (130 CT-P10; 128 rituximab). Over the study period, 115 (88%; CT-P10) and 111 (87%; rituximab) patients achieved overall response. At a median follow-up of 29·2 months (IQR: 26·1-33·7), median progression-free survival, time-to-progression, and overall survival were not estimable. The KM estimates (95% CI) for OS at 36 months were 98% (93-99) and 97% (89-99) in the CT-P10 and rituximab groups, respectively. Corresponding values for PFS were 80% (70-87) and 68% (54-79), while results for TTP were 82% (72-88) and 68% (54-79) in the CT-P10 and rituximab groups, respectively. (Figure A. OS; Figure B. PFS and Figure C. TTP) Over the study period, 114 (88%) and 104 (81%) patients in the CT-P10 and rituximab groups, respectively, experienced at least one treatment-emergent adverse event (TEAE) and 14 (11%) patients in each group experienced TE-serious adverse events (TESAEs). There were no unexpected safety findings observed during the second year of the maintenance period after single transition from rituximab to CT-P10.

Abstract Introduction: Disease control at five years would be a desirable endpoint for elderly multiple myeloma (MM) patients; however, the percentage of cases reaching this objective as well as the biomarkers to predict it, are not well defined. Objective and design: In order to gain further insight about long-term disease control (>5 years progression-free) in elderly MM we have analyzed a homogeneous population of 435 newly-diagnosed transplant-ineligible (TNE) patients enrolled in two consecutive Spanish clinical trials (GEM2005MAS65, GEM2010MAS65), that included both proteasome inhibitors and immunomodulatory drugs. Results: Amongst the 435 patients included in this post-hoc study, only 18.8% remained alive and progression-free after five years of initiating treatment. Noteworthy, in these patients the overall survival (OS) rate at 10-years was 69.4%, as compared to 11.4% for those patients progressing during the first five years (p< 0.001). Baseline variables significantly associated with long-term progression free survival in the univariate analysis were younger age, ISS 1, R-ISS 1, hemoglobin ≥ 12g/dl, normal LDH, and standard-risk cytogenetic abnormalities and the presence of a monoclonal gammopathy of unknown significance (MGUS)-like immunophenotypic profile in the bone marrow. Complete responses (CR) and minimal residual disease (MRD) negativity were also associated with long-term progression free survival. In the multivariate analysis, an hemoglobin level ≥12g/dl (OR 2.61; 95% CI 1.47 - 4.61, p=0.001) and a MGUS-like immunophenotypic profile in the bone marrow (OR 3.33; 95% CI 1.30 - 8.54, p=0.002) were the two baseline variables significantly and independently associated with a higher probability of long-term disease-free survival. When the depth of response (including MRD) was included in the logistic regression model, Hb level ≥12g/dl (OR 2.18; p=0.010) and the MGUS-like signature (OR 4.99, p<0.001) retained their independent predictive value along with the achievement of MRD-negativity (OR 4.09, p<0.001). Focusing on the 24 patients with an MGUS-like signature (based on the automated immunophenotyping analysis of the relative frequency of BM plasma cells (PCs) plus the percentage of clonal and normal PCs within the whole BM PC compartment), 50% percent of these patients displayed a long-term disease-free survival, as compared to only 17.5% of the remaining MM patients. The median OS for patients with MGUS-like signature was 90.2 months as compared to 62.6 for the MM-like patients. Most MGUS-like patients (90.5%) achieved a favorable response (10 complete response (CR) and 9 very good partial response (VGPR)). No differences in outcome were observed between VGPR and CR cases (p-value for OS 0.87) among MGUS-like patients. Conclusions: This study revealed that despite the usage of former novel agents, the probability of disease control at five years is still restricted to a small fraction (18.8%) of transplant-ineligible patients that achieve remarkable rates of long-term OS. Here, we identify that the combination of three biomarkers (normal Hb, MGUS-Like signature and MRD negativity) can help todefine elderly MM patients achieving long-term disease control. Our results highlight the presence of an MGUS-like signature in the bone marrow at diagnoses as the most powerful predictor for long-term disease free survival, and could be incorporated in clinical practice in order toimprove the prognostic information given to our patients.

Purpose: Hodgkin's lymphoma (HL) is a highly curable disease even in advanced-stage, with &gt;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= &lt;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 &lt;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 2406 The outcome for a given CLL patient is difficult to predict. While there are promising models, they require collation of multiple clinical and laboratory parameters, and it remains to be seen whether they will apply to typical CLL patients in the community. To further dissect out explanations for this dramatic clinical heterogeneity, we sought to understand genomic complexity of clonal B-cells as a possible explanation of clinical variability with specific application to genomic complexity as a predictor of therapeutic response and clinical outcome in CLL. Thus we wished to identified global gains and losses of genetic material in order to define copy-number abnormalities (CNA) in 48 clinically progressive CLL patients who were about to be treated on a chemoimmunotherapy protocol. This protocol was previously reported by us (Blood. 109:2007) and had an induction phase with pentostatin (2 mg/m2), cyclophosphamide (600 mg/m2) and rituximab (375 mg/m2) given every 3 weeks for 6 cycles and then responding patients were followed ever three months until relapse. In order to estimate CNA, we employed array-based comparative genomic hybridization (aCGH) using a one-million oligonucleotide probe array format on the leukemic B-cells from the 48 patients entering this trial. In those same patients, the aCGH data were compared to a) FISH detecxtable data using a panel for the common recurring genetic defects seen in CLL and b) to their clinical outcome on this trial. With aCGH we found that 288 CNA were identified (median of 4 per patient; range 0–32) of which 215 were deletions and 73 were gains. The aCGH method identified most of the FISH detected abnormalities with a complete concordance for 17p13.1- deletion (17p-) between aCGH and FISH. We also identified chromosomal gain or loss in ≥6% of the patients on chromosomes 3, 8, 9, 10, 11, 12, 13, 14 and 17. We found that CLL patients with ≥15 CNA had a significantly worse progression free survival (PFS) than patients with <15 CNA (p=0.004)(figure). Patients with ≥15 CNA also had a shorter duration of response than those with <15 CNA (p=0.0726). Of interest, more complex genomic features were found both in patients with a 17p13.1 deletion and in more favorable genetic subtypes such as 13q14.1. Thus, for 5 patients with >15 CNAs the following FISH patterns were seen: +12/13q14.1-x1/13q14.1 -x2, 13q14.1 ×1 (n=2), and 17p13.1 (n=2). In addition, a 17p- by FISH was positively associated with the number of CNA and total deletion size. The odds of having an overall response decreased by 28% (95% CI: 5–55%; p=0.015) with each additional CNA for the 17p13.1- patients. In addition to defining genomic complexity as the total number of CNA for each patient, we also defined complexity as the sum of the lengths of all interstitial chromosomal gains and losses. When defined as the total size of chromosomal gains or losses, genomic complexity was significantly associated with 17p13.1 and worse overall clinical response. In summary, this analysis utilized the global assessment of copy number abnormalities using a high-resolution aCGH platform for clinically progressive CLL patients prior to initiation of their treatment. One outcome was that we found higher genomic complexity was associated with shorter progression-free survival, reduced duration of response and predicted a poor response to treatment. In addition since we did find genomic complexity in more traditionally favorable FISH categories, such as 13q14.1 type defects, this may explain why some of the latter patients do not fare as well as might be expected even with aggressive chemoimmunotherapy approaches. This study adds information on the association between inferior trial response and increasing genetic complexity as CLL progresses. Disclosures: Off Label Use: Pentostatin.

Abstract Abstract 41 AuHCT improves survival in patients with MM, but disease relapse and progression remain a challenge. Both tandem AuHCT and post transplant maintenance therapy improve progression-free survival (PFS). Alternatively, allogeneic HCT has the potential to reduce disease progression through a graft-versus-myeloma effect. Use of nonmyeloablative conditioning regimens allows the latter approach to be used with reduced treatment-related mortality (TRM). BMT CTN 0102 was a multicenter phase III trial that biologically assigned patients with MM to auto-auto using melphalan 200mg/m2 (MEL 200) conditioning or an auto-allo approach using MEL 200 followed by alloHCT with 2 Gy total body irradiation. Graft-versus-disease (GVHD) prophylaxis was cyclosporine and mycophenolate mofetil. The primary endpoint was 3-year progression free survival (PFS). Between December 2003 and March 2007, 710 patients from 43 US centers were enrolled. Patients were assigned to the auto-allo arm based on availability of an HLA-matched sibling donor at time of enrollment. Patients in the auto-auto arm were further randomized to thalidomide and dexamethasone (Thal-Dex) for 1 year or observation (obs). Among 625 patients with SR MM (absence of chromosome 13 deletion by metaphase karyotyping and β-2 microglobulin ≤ 4mg/L), 436 were assigned to auto-auto (217 Thal-Dex, 219 obs) and 189 to auto-allo. Compliance with Thal-Dex was poor, with 84% of patients not completing prescribed therapy. PFS and overall survival (OS) between the Thal-Dex and obs cohorts were equal and these arms were pooled for the primary analysis. The auto-auto and auto-allo groups differed in age (median 55y vs. 52y, p =0.01) and time between first and second transplants (median 98d vs 105d, p =0.02), but were otherwise balanced. Complete and near complete (CR+nCR) response rates at study entry were 24% for both groups. Three-year PFS was 46% and 43% (p=0.67) and 3-year OS was 80% and 77 % (p=0.19) for the auto-auto and auto-allo groups, respectively. Corresponding probabilities for 3-year progression/relapse were 50% and 46% (p=0.8) and for 3-year TRM were 4% and 11% (p=0.04). Among auto-allo patients, probabilities of grade III-IV acute and chronic GVHD were 9% and 47%, respectively. Eighty-two percent of patients in each arm received the assigned second transplant. Among 522 patients who received their second transplant, 3-year PFS was 47% and 44% (p=0.89) with auto-auto and auto-allo, respectively. Disease response rates at day 56 after second HCT were: 50% very good partial response (VGPR) or better and 40% CR+nCR in the auto-auto group; and 49% (VGPR or better, p=0.8) and 48% (CR+nCR,p=0.12) in the auto-allo group. In conclusion, there were no differences in 3-year PFS and OS between patients receiving auto-auto or auto-allo. Potential benefits of graft-versus-myeloma to reduce disease progression or relapse were offset by increased TRM. Thal-Dex maintenance did not improve PFS or OS, likely due to poor tolerability of this regimen. At 3 years, the auto-allo approach for SR MM had no added benefit compared to tandem AuHCT.

Abstract Background: Melflufen is a highly potent anti-angiogenic compound that triggers rapid, robust and irreversible DNA damage and exerts its cytotoxicity through alkylation of DNA. The lipophilicity of melflufen leads to rapid and extensive distribution into tissues and cells where it binds directly to DNA or is readily metabolized by intracellular peptidases into hydrophilic alkylating metabolites. With targeted delivery of alkylating metabolites to tumor cells in vitro (such as multiple myeloma that are rich in activating peptidase), melflufen exerts a 20-100 fold higher anti-tumor potency and produces a 20 fold higher intracellular concentration of alkylating moieties compared with melphalan. Methods: Melflufen is evaluated in combination with dexamethasone (dex) 40 mg weekly in an ongoing Phase 1/2a study. RRMM patients with measurable disease and at least 2 prior lines of therapy are eligible (NCT01897714). Phase 1 established the maximum tolerated dose (MTD) of melflufen to be 40 mg every 3 weeks in combination with low dose dex. The primary objective of Phase 2a is the overall response rate and safety of the MTD in a total of 55 patients. Response was investigator assessed at the end of each cycle by IMWG criteria. Here we present the Phase 2 data as of 14 July 2015 data-cut. Results: Thirty-one patients were dosed at the MTD. The median time from initial diagnosis to first dose of melflufen was 6 years (1-15). The median number of prior therapies was 4 (2-9). 97% of patients were exposed to immunomodulatory drugs (IMiDs), 90% to proteasome inhibitors (PIs), 77% to melphalan, and 71% had received prior autologous stem cell transplant. 58% were double refractory (IMiDs and PIs) and 42% were triple refractory (IMiDs, PIs and alkylators). In total, 121 doses of melflufen have been given (1-11 cycles). Median treatment duration was 13 weeks with 9 patients still ongoing. One patient completed therapy as planned, 15 patients discontinued due to AEs (48%) and 6 due to progression (19%). Twenty-three patients were evaluable for response (protocol defined as ≥2 doses of melflufen with baseline and follow-up response assessments). One patient achieved a very good partial response and 10 patients achieved partial response (PR) (1 unconfirmed, still ongoing) for an overall response rate (ORR) of 48%. Three additional patients achieved minimal response (MR) for a clinical benefit rate (CBR) of 61%. Time to clinical benefit and response was rapid with 93% of patients achieving ≥ MR after 1-3 cycles and 64% achieving PR after only 1-3 cycles. Eight patients maintained stable disease and 1 patient had early progressive disease. Similar ORRs were seen in PI-refractory (43%), IMiD-refractory (40%), alkylator-refractory (62%), double-refractory (38%) and triple-refractory (50%) patients. The median progression free survival (PFS) is currently at 7.6 months (95% confidence interval: 3.4 - ∞) based on 14 events in 30 patients. The most frequent adverse events (AE), all grades, occurring in >10% of patients, regardless of relationship to study drug were thrombocytopenia (94%), anemia (84%), neutropenia (61%), leukopenia (42%), pyrexia (36%), asthenia (32%), fatigue and nausea (26%), bone pain (19%), cough, diarrhea, dyspnea, mucosal inflammation and upper respiratory infection (16%) and constipation and epistaxis (13%). Treatment-related Grade 3 or 4 AEs were reported in 27 patients (87%). Those occurring in >5% of patients were thrombocytopenia (68%), neutropenia (55%), anemia (42%), leukopenia (32%) and febrile neutropenia, fatigue, pyrexia, asthenia and hyperglycemia each occurred in 6% of patients. Serious AEs occurred in 9 patients (29%), but were only assessed as related to study drug in 5 patients (16%) including 3 febrile neutropenia, 1 fever and 1 pneumonia. Cycle length has recently been increased to 28 days to improve tolerability with respect to hematologic toxicity. Conclusion: Melflufen has promising activity in heavily pretreated RRMM patients where conventional therapies have failed. The current ORR is 48% and CBR is 61%. Similar results were seen across patient populations regardless of refractory status. The median PFS is encouraging at 7.6 months. Hematologic toxicity was common, but non-hematologic AEs were infrequent. Updated results will be presented at the meeting.

Abstract Median age at diagnosis of chronic lymphocytic leukemia is 72 years. However, only few patients over 80 years of age are included in clinical trials, even in those devoted to unfit patients. In order to evaluate both efficiency and safety of venetoclax in this category of patients, we conducted a multicentric retrospective study and collected data from 77 CLL patients from 19 FILO centers who started venetoclax after 80 years of age. Median age at venetoclax initiation was 86 years old (81-97). 63% of patients had a history of heart disease, 62% had renal failure (moderate 59% and severe 3%) and 29% had a history of severe infections. Despite their comorbidities and a CIRS greater than 6 in 70% of cases, their autonomy was preserved with a median performans status of 1 (0-4). In this comorbid geriatric population, pretherapeutic geriatric assessment was only performed in a single patient. The median number of prior therapies was 2 (0-6) with an exposure to a BCR inhibitor in 56% of cases. 11q and 17p deletion were found in 39% and 30% of cases respectively, 39% of patients had a complex karyotype and 30% harbored a TP53 mutation. However, in this real life population, these prognostic factors were only performed in half of patients. IGHV mutational status was only available in 11 patients, and 83% of them had unmutated IGHV. At the time of venetoclax initiation, the tumor lysis syndrome (TLS) risk was moderate in 57% of cases and high in 8% of cases. Venetoclax was administered as a single agent (42%) or in association with rituximab (58%). In total, half of the patients were hospitalized at each dose ramp-up, and only 3 patients were treated on outpatient basis. 82% of the cohort was able to reach the daily dose of 400mg. Half of the patients were included in a phone call monitoring program with oncology nurses to pre-emptively manage side effects and foster therapy adherence. The safety study reported 14% of TLS, with 2 discontinuations of treatment within the first month: one of which led to dialysis and the other to death. As in the previously published studies, 25% of patients had infectious complications, and grade 3 haematological and digestive toxicities were reported in 42% and 22% of cases, respectively. The reduction of the daily dose of venetoclax was necessary for 33%. Permanent discontinuation of venetoclax occurred in 40% of subjects, including 29% of early withdrawal (within the first 3 months). Main reasons for discontinuation were intolerance (21%), CLL progression (21%), death (21%) and scheduled treatment discontinuation (10%). The overall response rate was 86%, consisting of 49% of complete response (unconfirmed by bone marrow biopsy) and 37% of partial response. With a median follow-up of 21months, estimated progression free survival and overall survival were 29 and 38 months respectively. Prior exposure to a BCR inhibitor had no impact on progression free survival. To conclude, venetoclax has a manageable safety profile in elderly patients with comorbidities and can induce prolonged responses. Finally, if additional follow-up by oncology nurses seems to be more and more implemented, the pre-therapeutic onco-geriatric evaluation remains underexploited in this population.

Abstract Introduction In their lifetime, patients with follicular lymphoma frequently require multiple treatments, which have improved their survival over the past few decades. The expected treatment outcome based on lines of treatment in the post-Rituximab era is currently unknown. We analyzed the progression free survival and event free survival by line of treatment to aid estimating clinical endpoints when designing future clinical trials for multiply relapsed patients. Patients and Methods Adults (≥18 years) with de novo follicular lymphoma (FL) treated at our center between 1998 and 2007 were eligible (N=1134). 236 patients with ≤2 visits, mixed histology at initial diagnosis, and active concurrent malignancy were excluded. Of the remaining 898 patients, 105 were observed and did not require treatment during the timeframe of this dataset, and 2 had incomplete data, therefore 791 patients were eligible for response, progression and event free survival (PFS and EFS) analysis (Figure 1). Response was documented by investigators based on clinical or radiographic assessment. Complete response was based on radiographic assessment. PFS was defined as start of treatment to progression of disease or death. Patients with inadequate response to treatment, change of treatment, or stable disease without subsequent documented relapse were censored in the PFS analysis. Events for EFS were defined as progression, change of treatment, and death. PFS and EFS of sequential lines of treatment were evaluated by Kaplan-Meier method and compared across lines using log-rank test with adjustment for within-patient correlation. PFS and EFS were compared by other clinical variables using regular log-rank tests. Results Median age of diagnosis was 57.3 years with 1:1 male to female ratio. Median overall survival was not reached with median follow up of 9 years (N=898, range 0.2 - 16.8 years, Figure 1A). Median time to first treatment for the entire group was 2.3 months (range 0 - 13.3 years). In first line treatment of the 791 patients, 51% (N=406) received Rituximab with chemotherapy (R-Chemo), 13% (N=101) received chemotherapy only (Chemo), 19% (N=150) received Rituximab monotherapy (R-Mono), and 17% (N=129) received other treatments including radiation and surgery. For second line treatment, 405 patients were treated with about 37% receiving R-Chemo and 34% receiving R-Mono. As line of treatment increased, the percentage of patients with radiographically assessed complete response diminished from 71% at first line treatment to 25% by fifth line treatment (Figure 1B). Median PFS for first, second and third line treatment are 4.8, 1.6, and 1 year, respectively (Figure 2A). Median EFS for first, second and third line treatment are 3.8, 1.1, 0.8 year, respectively (Figure 2B). For subsequent lines of treatment, both median PFS and EFS were <1 year. Conclusion Follicular lymphoma is an indolent disease often requiring multiple lines of treatment. However, PFS and EFS for multiple lines of treatment in FL has not been described in the post-Rituximab era. The work has benchmarked the median response by line of treatment. After third line treatment, the PFS was ≤1 year. This analysis serves to aide comparison of different therapies for future drug approval in relapsed FL.

Background and Aim: Mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma (CTCL) wherein those with advanced stage have a poor prognosis. The objective of this study was to describe clinical characteristics and survival in MF patients who were refractory or had relapsed after a first systemic therapy. Methods: A retrospective chart review study was conducted at 27 sites in Europe. Patients enrolled had a diagnosis of MF and proved to be relapsed/refractory (R/R) prior to 1-Jan-2016 after a first systemic therapy. Overall survival (OS) and progression-free survival (PFS) were estimated from the date of R/R event (defined as the index date) using Kaplan-Meier estimates. PFS was defined as death, progression, second relapse or refractory, or presence of subsequent treatment after index date. Results: This study included 104 advanced R/R MF patients with a median age of 54.5 years (range: 21-82). The median follow-up was 3.5 years (range: 0-20.7) after index date. In total 80% of patients experienced a second R/R, with a median time to second R/R of 15.8 months (range: 0.6-174.6). The median age at death was 65 years (range: 42-85). In total 39 deaths (37.5%) were observed. Among those patients who had a known cause of death (N=35), 18 died of CTCL progression, 11 of CTCL complication or drug toxicity and 7 of other causes. The estimated median OS was 11.5 years (95% CI: 6.5 - not reached). The median PFS was 1.3 years (95% CI: 1.0-2.1). Conclusions: The high rate of R/R and low PFS suggest that the clinical burden of R/R MF is significant in five European countries, and recently approved targeted therapies have the potential of improving outcomes.

Abstract Background: The optimal duration of anticoagulation after a first unprovoked venous thromboembolism (VTE) is uncertain. Anticoagulant therapy is highly effective at reducing the risk of recurrent VTE, but this clinical benefit is not maintained once anticoagulation is stopped. Current guidelines suggest considering indefinite anticoagulation in all patients with unprovoked who have a non-high bleeding risk. However, this is a weak recommendation based on limited evidence. Deciding whether patients with a first unprovoked VTE should be considered for indefinite anticoagulant therapy requires estimation of the long-term risk of recurrent VTE after stopping anticoagulation. This risk however, is poorly established, hindering decision making. Methods: We performed a systematic review and meta-analysis of randomized clinical trials and prospective observational studies to determine the rate of recurrent VTE in the first year, in the second year, between years 2 and 5, and years 5 and 10; and the cumulative incidence for recurrent VTE at 2, 5 and 10 years after stopping anticoagulation in men and women with first unprovoked VTE, who had completed at least 3 months of initial treatment. Studies were identified through a comprehensive literature search using MEDLINE, EMBASE and the Cochrane CENTRAL databases. Data clarifications were requested from authors of eligible studies. Rates of recurrent VTE were calculated for each study from the total number of recurrent VTE events divided by the person-years of follow-up, and then pooled using random-effects meta-analysis. Results: Fourteen studies involving 6, 446 patients were included in the analysis. Among men with a first unprovoked VTE, the pooled rate of recurrent VTE per 100 person-years after stopping anticoagulation was 11.2 events (95% CI, 9.0-13.6) in the first year; 7.4 events (95% CI, 5.5-9.5) in the second year; 4.4 events/year (95% CI, 3.2-5.7) between years 2 and 5, and 3.8 events/year (95% CI, 1.6-6.9) between years 5 and 10 [Table 1]. Among women with a first unprovoked VTE, the pooled rate of recurrent VTE per 100 person-years after stopping anticoagulation was 8.6 events (95% CI, 6.5-11.0) within the first year; 5.2 events (95% CI, 3.5-7.2) in the second year; 3.0 events/year (95% CI, 1.6-4.7) between years 2 and 5, and 2.0 events/year (95% CI, 1.3-2.9) between years 5 and 10 [Table 1]. In men and women respectively, the cumulative incidence for recurrent VTE was 17.8% (95% CI, 14.0%-21.9%) and 13.4% (95% CI, 9.8%-17.4%) at 2 years, 28.2% (95% CI, 22.0%-34.4%) and 20.9% (95% CI, 14.0%-28.5%) at 5 years, and 40.8% (95% CI, 28.0%-53.9%) and 28.5% (95% CI, 19.5%-38.3%) at 10 years after stopping anticoagulant therapy [Table 2]. Conclusions: Among patients with a first unprovoked VTE who have completed at least 3 months of initial treatment, men have a higher long-term risk of recurrent VTE after stopping anticoagulation, and may be given greater consideration for indefinite anticoagulant therapy. Our findings affirm the importance of considering patient's sex in deciding the optimal duration of anticoagulation, and as such, emphasize the need for individualized, patient-centered approach for the long-term management of unprovoked VTE.

Introduction: There is a paucity of randomized trials to guide therapy for relapsed AL amyloidosis with treatment regimens generally extrapolated from experience in multiple myeloma. Methods: We conducted a retrospective review of patients who relapsed after receiving autologous stem cell transplant at Mayo Clinic. Patients treated for first relapse between January 2004 and December 2018 were included. Results: Three hundred and twenty-one patients were seen for relapsed AL amyloidosis post ASCT during the study period. Baseline characteristics were typical for a cohort with AL amyloidosis and are listed in Table1. 39% received therapy prior to transplant, conditioning in the majority (75%) was melphalan 200mg/m2. The median progression free survival from transplant (PFS1) was 30.7 months. Of the 321 patients 294 received treatment for relapsed disease. We categorized treatment regimens according to commonly used combinations and drug classes to further analyze outcomes. 34 patients were excluded from this analysis as they either proceeded directly to second ASCT (n=10) or received an atypical regimen not commonly considered for AL amyloidosis (n=24). Five categories of therapy regimens were identified, thalidomide based (n=110), melphalan plus steroids (n=31), 2nd generation immunomodulatory (IMiD) drug +/- alkylator (n=76), proteasome inhibitor (PI) +/- alkylator (n=116), PI plus IMiD (n=16), or daratumumab based (n=9). Disease and treatment characteristics for patients treated with these regimens are listed in Table 2. Patients treated with thalidomide had the shortest PFS1 (17.7 months) but PFS1 was similar for those treated with melphalan plus steroids, PI+IMiD and 2nd generation IMiDs (25.5, 24.3 and 25.6 months respectively). Patients treated with a PI +/- alkylator and daratumumab based regimen had the longest PFS1 (36.7 and 41.9 months respectively). The median duration of therapy was longer in patients treated with a 2nd generation IMiD or daratumumab based regimen (10.2, 12, 6.1, 5.5, 6.2 and 5.9 months for Dara based, 2nd generation IMiD, PI+/- alkylator, PI+IMiD, melphalan plus steroids and thalidomide based respectively). Hematologic response rate was lowest in those treated with melphalan plus steroids or thalidomide based regimens (44% and 55% respectively) and highest for patients treated with a PI+/- alkylator, (Figure 1). Progression free survival from relapsed therapy (PFS2) was longest amongst patients treated with daratumumab based regimens, PI +/- alkylator and 2nd generation IMiDs (not reached, 29.9 and 26.7 months respectively), Figure 2A. Overall survival from time of relapsed therapy favored patients treated with daratumumab based regimens, 2nd generation IMiDs and PI +/- alkylator, Figure 2b). Conclusion: A second generation IMiD based regimen or PI +/- alkylator produce high response rates and prolonged progression free and overall survival for relapsed AL amyloidosis. Patients treated with daratumumab based regimens and those treated with a PI plus IMiD also appear to do well, although numbers were low in our study. Patients treated with melphalan plus steroids or thalidomide based combinations have inferior outcomes and these regimens should be avoided.
