Abstract Introduction Immunoglobulin light chain amyloidosis (AL Amyloidosis) is a plasma cell disorder characterized by deposition of misfolded insoluble protein fibrils (composed of monoclonal κ or λ light chains) in tissues causing progressive organ dysfunction. Chemotherapy and autologous stem cell transplant (ASCT), when eligible, are standard treatment options but relapses remain inevitable for most patients. However, there is a paucity of literature describing relapsed or refractory patients. We performed a retrospective study to analyze the outcomes upon relapse and the impact of type of therapy and retreatment with the same therapy at relapse. Methods Clinical and laboratory data of 1327 consecutive patients with systemic AL amyloidosis seen at Mayo Clinic within 90 days of their diagnosis, between 2006 and 2015, was collected by chart review and analyzed retrospectively. Of these patients, 219 (16.5%) were lost to follow-up. Among the remaining 1108 patients, 366 patients experienced a documented hematological or organ relapse or progression requiring change of first line or start of second line therapy and form the current study population. Overall survival (OS) was calculated from start of second line treatment or progression mandating therapy until death from any cause or the date of last follow up. The OS was estimated using the Kaplan-Meier method and log rank test was used to estimate the difference in survival curves. Results The median age was 62.8 years (36.1 - 85.3); 63.1% were males; 64.7% / 59.3% / 11.4% had cardiac / renal / hepatic involvement and 24.2% / 32.1% / 23.3% / 20.3% had MS I/II/III/IV. The median estimated follow up for this cohort was 69.4 months (95% CI; 64.4, 76.8) from the start of first line therapy and 45.2 months (95% CI; 36.5, 50.6) from the start of second line therapy or progression requiring treatment. The median time to second line treatment or relapse /progression mandating therapy was 16.2 months (1-93) from the start of first line therapy. At relapse, 14 patients underwent ASCT, 165 were treated with proteasome inhibitor (PI) based therapy, 83 with immunomodulator (IMiD) based therapy, 33 with alkylator based therapy, 15 with a combination of PI and IMiD, 10 with steroids, 8 with other therapies and 38 did not receive treatment. Among the 366 patients, 124 (33.9%) required change or reinstitution of therapy during follow up at the time of analysis. The median time to third line treatment or relapse /progression mandating therapy was 31 months (95% CI; 24, 40.5) from the start of second line treatment. The median overall survival (OS) was 76.4 months (95% CI; 65.2, 83.6) from the start of first line therapy and 38.8 months (95% CI; 29.6, 52.6) from the start of second line therapy. The type of therapy at relapse (ASCT vs PI vs IMiD vs melphalan vs steroids and others) did not alter the time to next therapy (ASCT, 43.1m; PI, 31m; IMiD, 37m; melphalan, 20.8m; steroids and others, 20m; p=0.3) and OS (ASCT, 66.9m; PI, 51.1m; IMiD, 51.3m; melphalan, 37.2m; steroids and others, 80.7m; p=0.9) from the start of the second line treatment; as depicted in Figure 1. Retreatment with a different drug class (as the first line treatment) at relapse significantly reduced the time to next treatment (32.3m vs 22 m; p= 0.01) as compared to same therapy; but did not have any impact on survival (30.8m vs 51.1m; p = 0.5); as presented in Figure 2. Conclusion This study provides novel information about outcomes of patients with systemic AL amyloidosis who relapse or progress after first line therapy which could be useful in planning salvage therapies and designing clinical trials. Retreatment with a different therapy at relapse improves time to next therapy but does not impact OS. Hence, we conclude that the patients can fare well post relapse/ progression and can benefit from various treatment regimens including retreatment with the same agent.

Introduction: Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma in the Western hemisphere. Patient characteristics and burden of FL are incomplete and vary from previous studies. This study evaluated patient profile, including patient characteristics, treatment patterns, and duration using real-world data. Methods: Using the Truven MarketScan® databases, patients with FL who were newly initiated with FL indicated regimens were identified from 1/1/2010-12/31/2013 (initial treatment identification period). Patients were selected if they were ≥18 years old, had 1 FL ICD-9 code (202.0) as primary or secondary diagnosis, at least 1 FL commonly prescribed systemic anti-cancer therapy after the diagnosis, and did not use any FL indicated regimen in the past 6 months prior to first agent included in the initial treatment identification period. These patents were followed ≥3 months or to June 30, 2018. Primary outcomes were the distribution of regimens by line, the number of patients who switched from first- to second-line therapies, and from second- to third-line therapies. The treatment duration by line of therapy and regimen were also analyzed. Discontinuation was defined as 3 months without receiving a regimen after treatment. Results: This study identified 4,970 patients who initiated treatment for FL. Of these patients, 48.1% were female (n=2,390), with a mean age of 62.0 (SD: 14.0) years. The average follow-up time was approximately 2 years (median: 733 days). In this analysis, 4,970 patients with FL received first-line therapy for 153 days (median: 94 days), 1,985 received second-line therapy (39.9% of patients who received first-line therapy) for 208 days (median: 80 days), and 664 received third-line therapy (13.4% of patients who received first-line therapy) for 117 days (median: 43 days). Of the 4,970 patients on first-line therapy, 453 (9.1%) remained on first-line therapy, 2,532 (51.0%) discontinued treatment, and 1,985 (39.9%) patients switched to the next line of therapy during the follow-up period. Of the 1,985 patients who switched to second-line therapy, 328 (16.5%) remained by the end of follow-up period, 993 (50.0%) discontinued, and 664 (33.4%) switched to the next line of therapy during the follow-up period. Of the 664 patients who switched to third-line therapy, 125 (18.8%) remained, 269 (40.5%) discontinued, and 270 (40.7%) switched to the next line of therapy. The most common first-line regimens in descending order received by patients were rituximab (n=1,478, 29.7%), R-CHOP (n=1,368, 27.5%), BR (n=1,050, 21.1%), R-CVP (n=371, 7.5%), and FCR (n=63, 1.3%). Second-line treatment regimens were (N=1,985) rituximab (n=992, 50.0%), BR (n=202, 10.2%), R-CHOP (n=138, 7.0%), and R-CVP (n=120, 6.1%). Third-line treatment regimens were (N=664) rituximab (n=228, 34.3%), BR (n=91, 13.7%), R-CHOP (n=75, 11.3%), cyclophosphamide (n=35, 5.3%) and R-CVP (n=31, 4.7%). Conclusion: This data set describes the percentage of patients that transition from first- to second-line and second- to third-line treatment for FL. The primary regimens used across the treatment lines conform to those recommended by the NCCN guidelines. In addition, smaller numbers of non-recommended regimens were reported.

Abstract Introduction: Light chain burden in light chain (AL) amyloidosis is often low, making accurate response assessment challenging. Methods: AL amyloidosis patients achieving very good partial or complete response to first line therapy and had serial sFLC studies during and after completion of therapy were included (n=396). Involved free light chain (iFLC), difference in involved-to-uninvolved free light chains (dFLC) and sFLC ratio (sFLCR) were assessed at the end of first line therapy and at nadir iFLC. Survival analysis was done using the Kaplan-Meier method. Hematological progression-free survival (hemPFS) was defined as the time from diagnosis until hematological progression or death, where patients known to be alive and progression-free at the end of follow-up were censored. Hematological progression was defined according to consensus criteria or upon initiation of second line therapy, whichever came first. Results: The median iFLC and dFLC at the end of therapy was 1.7 mg/dL and 0.5 mg/dL, respectively. sFLCR normalization occurred in 70% of patients. iFLC ≤2 mg/dL and dFLC ≤0.5 mg/dL were associated with a longer hemPFS compared to their counterparts (Figure). Only iFLC ≤2 mg/dL was associated with a significantly longer overall survival (Figure). sFLCR normalization did not predict hemPFS or overall survival. Organ response was predicted by iFLC ≤2 mg/dL and dFLC ≤0.5 mg/dL (Table), with best discrimination seen with iFLC ≤2 mg/dL. Organ response was not predicted by sFLC normalization (Table). The median nadir iFLC was 1.4 mg/dL and was reached 3.9 months from the end of therapy, longer in transplanted patients compared to patients treated with non-transplant regimens (7.3 vs 1.8 months, respectively; P<0.001). iFLC ≤2 mg/dL at the completion of therapy and nadir iFLC reached >12 months from the end of therapy were favorable predictors of hemPFS/OS in a multivariate analysis. Conclusion: iFLC at the end of first line therapy better predicts for organ response and survival than dFLC among deep responders. Normalization of sFLCR does not predict for organ response or survival and should not be used as measure of therapeutic efficacy. Figure. Figure.

Background: Multicentric Castleman's disease (MCD) is a rare lymphoproliferative disease accompanying various symptoms and multi-organ dysfunctions. Although anti-interleukin-6 monoclonal antibodies, tocilizumab and siltuximab are recommended as a therapeutic option, these treatments require patients to visit hospitals at least once a month for many years, and the drug costs are quite high. In Japan, where tocilizumab is the only biological agent covered by the medical insurance, glucocorticoid monotherapy is still an important treatment option. In fact, a part of MCD patients initially treated with glucocorticoids could be successfully controlled without adding or switching to other agents. Considering that emergence of neutralizing anti-drug antibodies which reduced therapeutic efficacy could also be a clinical problem in MCD, there would be a rationale for reserving newer agents for future relapse by using glucocorticoids as first-line treatment for potential responders. Here, we retrospectively analyzed clinical characteristics of MCD patients treated in our institution to explore factors predicting who could be successfully treated with glucocorticoid monotherapy. Methods: We retrospectively reviewed histologically confirmed Castleman's disease patients who visited the Department of Hematology and Oncology of the University of Tokyo Hospital from January 2000 to March 2020. Based on the diagnostic criteria of Castleman Disease Collaborative Network (CDCN), MCD was diagnosed when enlarged lymph nodes were present in more than 2 lymph node stations and laboratory and/or clinical diagnostic criteria were met. Unicentric Castleman's disease (UCD) was diagnosed when only one single lymph node region was involved. MCD patients who were initially treated with prednisolone (PSL) were divided into two groups: patients who continued PSL until the latest follow-up (PSL-only group) and patients who received subsequent treatment (Second-line group). Results: 8 patients with UCD and 27 patients with MCD were included in our analysis. With a median follow-up of 5.2 years, 21 MCD patients underwent first-line treatment (PSL, n=18; tocilizumab, n=3). Compared to patients who did not receive any treatment, patients who underwent treatment had marginally higher levels of CRP (7.15 mg/dl vs 4.17 mg/dl, respectively; p=0.066) and significantly lower levels of hemoglobin (9.5 g/dl vs 12.5 g/dl, respectively; p=0.036). Seven out of 18 patients initially treated with PSL had received subsequent treatments (tocilizumab, n=6; rituximab, n=1). Among the PSL-only group, biochemical responses at the latest follow-up could be assessed for 10 in 11 patients: two in complete response, five in partial response, two in stable disease, and one in progressive disease, based on the response criteria of CDCN. Compared to PSL-only group, patients classified into second-line group had higher levels of CRP (11.88 mg/dl vs 6.24 mg/dl, respectively; p=0.024) and lower hemoglobin levels (6.4 g/dl vs9.4 g/dl, respectively; p=0.033). Patients whose CRP levels were lower than 12 mg/dl before starting PSL had significantly longer time to next treatment (TTNT) (median not reached vs 0.88 years; HR, 0.078 [95%CI: 0.013-0.48], p=0.00044). Similarly, patients whose hemoglobin levels were more than 8 g/dl had marginally longer TTNT (median not reached vs 2.63 years; HR, 0.22 [95%CI: 0.040-1.17], p=0.054). In addition, patients with either Hb &lt; 8 g/dl or CRP ≧12 mg/dl had significantly shorter TTNT (median not reached vs 2.12 years; HR, 0.090 [95%CI: 0.010-0.77], p=0.0074). The median PSL dose at the latest follow-up in PSL-only group was 3 mg per day [interquartile range: 0-5 mg per day], which would be comparably safe considering previous reports indicating that PSL dose of less than 5 mg per day was associated with lower incidence of adverse events. Conclusion: Out data suggest that glucocorticoid monotherapy has a good potential to induce sustained disease control for MCD patients with higher Hb or lower CRP levels. Furthermore, PSL doses could be tapered to safer doses among patients who could continue PSL until the latest follow-up. In contrast, the efficacy of glucocorticoids for MCD patients with lower Hb or higher CRP levels were limited. Such patients would be good candidates for novel agents such as tocilizumab or rituximab. Disclosures Honda: Nippon Shinyaku Co., Ltd.: Speakers Bureau; ONO PHARMACEUTICAL CO., LTD.: Speakers Bureau.

Background:Immune thrombocytopenia purpura (ITP) is an autoimmune bleeding disorder that is heterogeneous in presentation, disease course, treatment response, and impact on quality of life. Treatments often cause unpleasant side effects, and prolonged use can lead to tolerability issues and toxicity. Both disease symptoms and treatments available impact the health-related quality of life (HRQoL) among patients living with this rare condition. Here, we compare self-reported fatigue and its impact among adult ITP patients and determine whether these fatigue levels differ depending on treatment status. Methods: For this study, we used three of the five surveys from the PDSA Natural History Study Registry including; treatment history and two adult QoL surveys. As of June 2020, 357 adult patients completed the survey assessing treatment history. A total of 310 adult patients completed the adult QoL (part one) survey, and 301 adults completed the adult QoL (part two) survey. Patients were stratified by 1) no treatment received 2) treated in the past 3) on therapy within the last six months; patients currently on therapy were further stratified by first and second-line therapy. Results: Among the 357 completed surveys on treatment history, 11% (n=40) reported they have never received treatment for their ITP, while 46% (n=166) have in the past, and 43% (n=158) currently receive therapy (within the last six months). Among those currently on treatment, 82% receive monotherapy; 47 (26%) use a first-line therapy (corticosteroid, IVIG, or Anti-D), and 78 (43%) are using a second-line therapy (TPO-RA, rituximab, and other second-line options). Therapies reported include TPO-RA's (41%), corticosteroids (24%), IVIG (7%), rituximab (3%), SYK inhibitor (1%), antibiotics (4%), anti-D (1%), other second-line treatments (such as MMF, dapsone etc.), and "other" therapies including complementary treatments (14%). Overall, 93 (23%) reported having had a splenectomy at some point to manage their active ITP. When asked to reflect on general tiredness, 98% of patients (n=310) reported being tired overall, with 55% reporting feeling tired 'almost always/often' regardless of treatment group or type. Those who have never been treated reported they felt tired 94% of the time, and 55% reported feeling tired 'almost always/often'. Among those who are not currently on treatment (but have received therapy in past), 99% reported feeling tired overall, and 50% reported feeling tired 'almost always/often'. Respondents using a first line therapy reported feeling tired overall 100% of the time, and reported feeling tired 53% 'almost always/often'. Respondents using a second line therapy reported feeling tired 99% of the time, and indicated they were tired 59% 'almost always/often'. There were no significant differences between these treatment types and groups identified. When asked to reflect on fatigue levels over the last seven days, collectively, 86% reported fatigue, and 30% reported experiencing it 'very much/quite a bit'. Among those who had never been treated, 85% reported fatigue, and indicated they felt fatigue 27% of the time 'very much/quite a bit'. Respondents who were not receiving treatment reported feeling fatigue 84% of the time, of which 26% was experienced 'very much/quite a bit'. Among those receiving a first line therapy, 90% reported fatigue in the last seven days, and 34% reported they experienced this 'very much/quite a bit'. Those using a second line therapy reported feeling fatigue 91% of the time, and 29% reported this was 'very much/quite a bit'. There were no significant difference among these treatment types and groups. Conclusion: Reported fatigue and overall tiredness are high among those currently on treatment, not on treatment, and those who have never been treated for their ITP. We did not find that fatigue levels were related to treatment type or group, indicating that the underlying causes may not be platelet count, or disease severity, but rather a combination of factors associated with having an unpredictable chronic disease. The multi-faceted effects of ITP often take a significant toll on patients' quality of life. The registry continues to collect data with the intent of understanding the longitudinal impact of ITP and in future with more of a sample size we can learn if these trends continue.

Introduction: Bruton tyrosine kinase (BTK) is a critical component of the B-cell receptor pathway, and is a validated target for the treatment of chronic lymphocytic leukemia (CLL). Ibrutinib is a first-generation, covalent, small molecule BTK inhibitor approved for the treatment of CLL. We present a preliminary analysis of treatment patterns and adverse events (AEs) in patients with CLL treated with ibrutinib in a real-world setting. Methods: A retrospective chart review is being conducted among patients diagnosed with CLL and treated with ibrutinib in oncology centers throughout the UK; the target sample size for the study is 250 patients. Patients are eligible if they initiated ibrutinib after diagnosis of CLL, between January 2017 and June 2018, with at least 12 months of follow-up data available, with the exception that patients who died less than 12 months after ibrutinib initiation remained eligible. Hematology/oncology physicians reviewed medical records and completed web-based data collection forms. Baseline medical history information and data on treatment characteristics and AEs were collected. By June 2019, a total of 151 medical records (60% of the target sample size) had been abstracted. All analyses were descriptive in nature and were performed in SAS v9.4 or later (Cary, NC, USA). Results: Twenty-two physicians from specialist cancer centers or tertiary referral treatment centers (45.5%), teaching hospitals (31.8%) and non-teaching hospitals (22.7%) submitted data on ibrutinib-treated patients. The median follow-up for this interim sample of 151 patients was 16.1 months (range: 2.8-27.5 months) from ibrutinib initiation (index date) and 61.7 months (range: 11.6-264.1 months) from initial CLL diagnosis (Table 1). Median age was 71 years, 56% were male, 22.5% of patients had del(17p) mutation and 24.5% had TP53 mutations/aberrations. Of the 151 patients, 24.5% (n=37) initiated ibrutinib as first-line therapy while 75.5% (n=114) initiated ibrutinib as second- or later-line treatment. Median time to initiation of ibrutinib was 3.8 months (range: 0.3-123.7 months) for first-line therapy after initial CLL diagnosis and 22.3 months (range: 0.2-242.2 months) for second-line therapy after end of first-line therapy. Other therapies that patients received besides ibrutinib included the combination of fludarabine, cyclophosphamide, and rituximab (first-line, 22.5%; second-line, 1.7%), bendamustine plus rituximab (first-line, 19.9%; second-line, 15.5%), and chlorambucil plus rituximab (first-line, 10.6%; second-line, 1.7%). The most common AEs observed during ibrutinib therapy were bruising (19.9%), cytopenias (18.5%), diarrhea (15.2%), and arthralgia (11.3%) (Table 2). Conclusion: This preliminary analysis describes patient characteristics and treatment patterns in ibrutinib-treated patients in the UK. We found that the majority of ibrutinib use was in the second-line or later, reflecting the current UK public reimbursement situation.

Introduction: About 2 to 10% of patients (pts) diagnosed with Chronic Lymphocytic Leukemia (CLL) develop diffuse large B-cell lymphoma (DLBCL, so-called Richter transformation (RT)) over long-term follow-up. The outcomes of pts with RT are variable and poorly understood and there is no consensus on the best therapeutic approach. The aim of this study was to analyze the clinical characteristics, outcomes and factors predictive of survival in a large series of RT from the French Innovative Leukemia Organization (FILO). Methods: Biopsy-confirmed RT (limited to DLBCL and excluding Hodgkin lymphoma) diagnosed from 2001 to 2018 were identified from eight FILO centers. Clinical and biological characteristics of CLL and RT at diagnosis, including cytogenetics, clonal relation with the pre-existing CLL, Epstein-Barr virus (EBV) status, cell of origin (COO) analyzed by immunohistochemistry and RT score (Tsimberidou AM et al, J Clin Oncol, 2006) were analyzed as well as treatment and outcomes. Overall survivals (OS) were defined as time from CLL and RT diagnosis to death from any cause and analyzed using the Kaplan-Meier method. Statistical analyses were performed with SAS version 9.4. Results: A total of 70 CLL pts who developed RT were identified. The median age at CLL diagnosis was 62 years old (range 35-82), and 50 (71.4 %) were male. The median time to transformation was 5.5 years (range 0 to 22 years), with 12 simultaneous diagnosis of CLL and RT. Prior to RT, 20 (29%) pts had not been treated for CLL, 50 received one (n=21) or more (n= 29) line of treatment ; 6 pts had received a novel agent (ibrutinib, idelalisib or venetoclax). The median age at RT diagnosis was 68 years old (range 42-88). All biopsies were centrally reviewed; 38/58 pts (66%) had elevated LDH (>1.5N) ; 35/65 pts (54 %) had bulky disease (≥ 5 cm); 10/54 (18.5%) pts had del(17p) or TP53 mutation ; 9/42 pts (21%) had a complex karyotype (at least 3 abnormalities). The CLL and RT were clonally related in 27/27 (100%) tested pts. COO by Hans algorithm was non germinal center B cell-like (GCB) in 26/28 pts (93%). EBV was positive or detected in 5/40 (12.5%) pts. The median of Ki67 positivity was 70% (range 30% to 100%). The RT score (based at RT diagnosis on ECOG performance status 2-4, LDH >1.5 x normal, platelets<100 x 109/L, tumor size >5 cm and >1 prior therapy for CLL) was : low risk in 17 pts (31%), low-intermediate risk in 10 pts (19%), high-intermediate risk in 14 pts (25%) and high risk in 14 pts (25%). The most common first-line treatment of RT was immunochemotherapy (n=57, 87%) including R-CHOP-like regimen (n=48, 73%). Autologous or allogeneic transplantation was performed for 7 pts (11%). Response to first-line treatment was complete or partial response in 26 pts (40%), and stable disease or progression in 39 pts (60%). After a median follow-up of 8 years, 51/64 pts (80%) have died. The main causes of death were progressive DLBCL (n=36, 71%), infection (n=8, 16%) or progressive CLL (n=2, 4%). The median OS of the cohort from CLL and RT diagnosis (Figure 1) were 7.8 years and 9.5 months, respectively. In univariate analysis, patients with TP53 disruption at CLL stage, low platelets count, elevated LDH, elevated beta2-microglobulin, high ECOG score, high RT score, EBV positivity and absence of response to first-line RT treatment had worse OS. The ECOG score, platelets count and TP53 disruption remain significant in multivariate Cox-regression. Last, we compared the clinical and biological parameters of two Richter groups defined as: (i) short-term survivors (<12 months, n = 34) and (ii) long-term survivors (>48 months, n = 18). Long survival was significantly associated with elevated platelets count, low LDH, low ECOG, low RT score and response to RT first-line treatment. Discussion: The clinical outcomes of RT patients is poor and novel treatment options are needed. However, a group of long-term survivors was identified, characterized by elevated platelets count, low LDH, low ECOG, low RT score and response to immunochemotherapy.

Abstract Introduction Among patients with aggressive B-NHL who fail RCHOP, about half respond to standard salvage regimens and may proceed to curative-intent, transplant-based therapy. However, whether pts failing more intensive regimens such as dose-adjusted, infusional EPOCH benefit from standard salvage regimens is unclear. We hypothesized that such patients comprise a higher-risk cohort, facing inferior response rates and outcomes using standard salvage regimens. We undertook a collaborative study to assess response rates and survival among pts failing EPOCH for aggressive B-NHL, to inform patient management and design of clinical trials in this setting. Methods Pharmacy records and institutional databases were queried, identifying pts receiving EPOCH over the last 10 years at the University of Washington/SCCA and the Cleveland Clinic Foundation, for combined analysis. Under IRB approval, patient characteristics, histology, outcome with EPOCH, time to EPOCH failure, response to salvage, and overall survival were analyzed. Diffuse large B cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma, B-cell-lymphoma unclassifiable, HIV-associated B cell lymphoma, and transformed B cell non-Hodgkin lymphoma were included. Pts receiving <2 cycles EPOCH, or who had inadequate follow-up (<3 months), were excluded. Failure of EPOCH was defined as failure to respond or progression during therapy, need for initiation of salvage therapy, or death during therapy of any cause. Adverse events or treatment change due to toxicity were not included in the definition of failure. JMP 11 was used to generate kaplan-meier survival estimates. Results 124 pts with aggressive B-NHL receiving EPOCH were identified. 54 had not relapsed, and among 70 remaining da-EPOCH failures, 37 met the above inclusion criteria. Median age was 55. 27% were female, and 23 received EPOCH as first-line therapy. All but 3 received rituximab with EPOCH. Histologies were primarily DLBCL in 22/37 (60%) and BCL-U in 12/37 (32%) carrying a MYC translocation; most of these harbored additional translocations in BCL2 and/or BCL6 (10/12). However, data regarding MYC rearrangement was not available for all pts. 2 had HIV-associated B-NHL and 3 had PMBCL. With 18 months follow up, the median time to EPOCH failure was 5 months. Only 3 EPOCH failures occurred late (>12 months). Median OS from the date of EPOCH failure was 10 months (Figure 1). Those receiving EPOCH as first-line therapy (23) had a median OS of 14 months from EPOCH failure, as opposed to 4 months for those receiving EPOCH as salvage therapy (log-rank p=.01). Salvage chemotherapy regimens after EPOCH were diverse, and generally ineffective; 6/28 (21%) regimens produced a response (Table 1). Among patients failing EPOCH within a year, platinum-containing salvage (RICE/RDHAP) was effective in only 2/13 patients (15%). 9 patients did not receive any salvage, most of whom died or proceeded to palliative measures and/or hospice care. Conclusions A relatively low overall response rate (21%) was observed in this retrospective analysis of patients failing EPOCH. Analogous to early RCHOP failure in the CORAL study, those failing EPOCH within a year may face inferior outcomes with platinum-based salvage therapy. While combined from two institutions, our data represent a modest sample size and require confirmation. If verified, examination of mechanisms of resistance to EPOCH, and selecting EPOCH failures for clinical trials of novel targeted therapies and transplant-based approaches, may prove critical.

Abstract Introduction Immunoglobulin light chain amyloidosis (AL Amyloidosis) is a monoclonal plasma cell proliferative disorder that is characterized by tissue deposits of misfolded insoluble κ or λ light chain derived amyloid fibrils, leading to organ dysfunction. The prognosis of patients depends on the number and severity of organ involvement, especially cardiac involvement. Autologous stem cell transplant (ASCT), if eligible, alkylator (melphalan) and novel drugs like proteasome inhibitors (PI) and immunomodulators (IMiD) have improved the overall survival (OS) during the past decades. But still, nearly half of the patients die within a year of diagnosis. We analyzed the factors predicting early relapse / progression or death (within 12 months) after first line therapy for systemic AL amyloidosis. Methods Clinical and laboratory data of all consecutive patients with systemic AL amyloidosis seen at Mayo Clinic within 90 days of their diagnosis, between 2006 and 2015, was collected by chart review and analyzed retrospectively. Patients who died within 3 months of starting the first line treatment were excluded from analysis. Early relapse (ER) was defined as relapse / progression requiring treatment change / re-institution or death within 12 months of starting first line treatment. Patients in the cohort with ER were compared with patients with a follow up of more than 12 months who had a relapse / progression beyond 12 months or had continuing response at the time of analysis. Categorical variables were analyzed using chi - square and Fisher's exact test and continuous variables using Kruskal- Wallis test and Wilcoxon rank sum test. Multivariate analysis was done using logistic regression model. Results Seven hundred and eighty six patients with newly diagnosed systemic AL amyloidosis met the study criteria and were included in the analysis. Among these, 230 (29.3%) patients had ER within 12 months of starting initial therapy while 556 (70.7%) patients either relapsed after 1 year or had continuing response at the time of analysis. Baseline demographics, organ involvement and type of first line therapy are presented in Table1. The median estimated follow up for the entire cohort from start of initial therapy was 62.9 months (95% CI; 59.9, 67.3). The variables included in the univariate and multivariate analyses for factors predicting ER were age at diagnosis (≤ vs > 70 years ), revised mayo stage (I and II vs III and IV), bone marrow plasma cell percentage (BMPC; ≤ 10% vs > 10%), presence of any chromosomal abnormalities, trisomies or IgH translocations by fluorescence in situ hybridization (FISH), multiorgan involvement [(>1 vs 1) (heart, liver, kidney, gastrointestinal tract, autonomic neuropathy), incorporation of ASCT in initial therapy. In univariate analysis, mayo stage (p<0.0001), multiorgan involvement (p=0.0008) and inclusion of ASCT as part of initial therapy (p<0.0001) were significantly associated with ER, while age (p=0.06), BMPC(p=0.9), FISH abnormalities (p=0.2) were not. However, in multivariate analysis, only mayo stage (III + IV vs I + II; p=0.01) and non-inclusion of ASCT in first line treatment (p=0.0001) were significantly predictive of ER. Conclusions Despite the introduction of ASCT and novel drugs, the early mortality in systemic AL amyloidosis remains high. This study demonstrates that patients with ER are older with higher prevalence of cardiac involvement and multiorgan involvement and higher Mayo stage (III and IV). Incorporation of ASCT as part of the initial therapy was associated with reduced early relapse, but it is difficult to separate the influence of the eligibility for ASCT from the effect of ASCT itself. This will help us in characterizing these patients to better understand their mechanisms of resistance to therapy and gives an insight to the type of initial therapy that benefits them.

Abstract Background: Among patients with immunoglobulin light chain (AL) amyloidosis, there is little consensus on when reinstitution of chemotherapy should occur (Milani and Dispenzieri, International Society of Amyloidosis 2016). AL amyloidosis patients who are treated with high dose chemotherapy followed by autologous stem cell transplant (ASCT) are a relatively low-risk and homogenous population, making them an ideal group to study practice patterns. Methods: We conducted a retrospective study to evaluate the patterns of relapse or progression and the timing of re-initiation of therapy among 146 patients who were initially treated with ASCT at Mayo Clinic between 1996 and 2009 and who received second-line therapy between 7/9/1997 and 4/12/2012. Results: The median time from ASCT to second-line therapy was 23.6 months and the median follow up post ASCT was 57.5 months. The indications for second-line treatment were: 1) both hematologic and organ progression 24.7% (36 patients); 2) organ progression only 41.1% (60); 3) hematologic relapse only 34.2% (50). The median dFLC at the time of starting second-line therapy was 10.5 mg/dL (1.6 - 59.5 mg/dL), which was 44.9% (13.8-167.2%) of dFLC level at diagnosis. Increase in proteinuria by > 50% from nadir (that was also at least 1g/24 hours, i.e. renal progression) was present in 35.8%. Increase in NT proBNP by >30% from nadir and minimum of 300 pg/mL was present in 48.9% of patients. The respective 4 years overall survival rates from the time of ASCT were 87.8%, 63.9%, and 56.7% (p=0.0016) for patients who had hematologic relapse, organ progression only and both organ and hematologic progression. Comparisons of laboratory markers at diagnosis, nadir of post ASCT and initiation of second-line therapy are listed in the table. Conclusions: Our study investigated the patterns of relapse / progression following upfront ASCT. This provides some insights on practice patterns of when physicians re-initiate therapy. Table Table.

Abstract Introduction: As there is limited evidence to guide management of patients with steroid-refractory graft-versus-host disease (SR-GVHD) there is a broad variability of clinical practices. To document the current practice and assess the impact of emerging new drugs in SR-GVHD, Transplant Complications Working Party (TCWP) of the EBMT performed a survey among EBMT centers that covered specific treatment decisions on first- and second-line treatment of acute and chronic GVHD (aGVHD and cGVHD). Methods: The survey was conducted from December 2020 to March 2021 among EBMT centers. A questionnaire was developed by the study authors and used for data collection. It consisted of 40 questions focused on general approach in the first-line treatment, preferred second-line treatment in SR-GVHD and ancillary care in aGVHD and cGVHD. Results: 145 centers from 33 countries agreed to participate and responded to the questionnaire. First-line treatment of aGVHD was reported as rather homogenous; with most centers (68%) starting with lower doses of corticosteroids (CS) (&lt;2mg/kg) in lower grade aGVHD (grade 2a) and most centers (88%) starting with higher doses (2mg/kg) in aGVHD grades &gt;2b. On the other hand, the evaluation of response to CS was more heterogeneous: at 3 days in 33%, at 5 days in 30%, at 7 days in 15% of centers and depending on severity of aGVHD in most other centers. In the presence of SR-aGVHD, 50% of centers consider inclusion of patients in clinical trials. Although as much as 85% of centers reported to have a standard operating procedure (SOP) for SR-aGVHD management, only 45% (n=66) have an established one or 2-agent second-line treatment; most frequently ruxolitinib (n=46) and/or extracorporeal photopheresis (ECP) (n=29). All other centers reported a very heterogeneous practice and listed multiple agents (range, 3-10) as second-line treatment options. In total, the most used agents for SR-aGVHD as shown in Figure 1A are ruxolitinib in 68%, ECP in 59%, mycophenolate-mofetil (MMF) in 27%, calcineurin inhibitors (CNI) in 25%, high-dose CS (&gt;2mg/kg) in 15%, mesenchymal stem cells (MSC) in 14%, etanercept in 13%, infliximab in 11% and anti-thymocyte globulin (ATG) in 10% of centers. Clinical practice in first-line treatment of cGVHD again appeared relatively homogeneous; 58% of centers reported to treat mild forms with topical treatment only, unless affected organs could not be reached topically. In moderate/severe cGVHD, the majority (71%) of centers start with 0.5-1mg/kg of CS, in 45% with addition of CNI, while others use higher doses of CS +/- other agents. The evaluation of response was done before 4 weeks in 41% of centers, between 5-8 weeks in 41%, while a minority performed later response assessment or based the latter on organ affection/severity. In case of SR-cGVHD, 56% of centers would consider the inclusion in clinical trials, while only 65% have a SOP on management of these patients. One third of centers (35%) has an established multidisciplinary cGVHD team. Practices for SR-cGVHD again varied significantly, with most centers reporting on the use of more than 2 agents (range, 3-13) as second-line and with most applied agents as depicted in Figure 1B; ruxolitinib and ECP in 68% of centers, CNI in 40%, MMF in 37%, rituximab in 27%, imatinib in 25%, mTOR inhibitors in 23%, ibrutinib and methotrexate (MTX) in 19%, pulse of CS in 17%, MSC in 12% and PUVA therapy in 10% of centers. Conclusions:In summary, this survey revealed a rather homogenous first-line management of aGVHD and cGVHD based on steroids in the majority of centers. However, when first-line fails, the definition of SR-GVHD remains highly variable and SR-GVHD is still treated with a seemingly "trial and error" approach as demonstrated by significant variability of clinical practices among EBMT centers for second-line treatment. However, in line with recently published prospective trials, ruxolitinib comes forth as one of the most used therapeutic modalities in both SR-aGVHD and cGVHD, together with already widely administered ECP. On the contrary, ibrutinib has not emerged as standard of care in this setting. Future efforts should be invested in finding a standardized approach in SR-GVHD by directly comparing most applied second-line agents in prospective trials as well as evidence-based personalized treatment approaches.
