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.

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.

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.

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 Advances in the management of multiple myeloma (MM) led to a significant prolongation of overall survival (OS), mainly of the younger patients; almost 10% of them experience more than 10-year OS. Although long progression-free survival (PFS) correlates with extended OS, there is very limited information for the characteristics of patients who manage to be progression-free for a long period after first-line therapy. The aim of this analysis was to evaluate the characteristics of patients who achieved at least 7-year of PFS after frontline therapy and compare them with those of all other patients who were treated in a single center during the same time period. Between January 1994 and December 2010, 406 consecutive newly diagnosed MM patients received first line therapy in the Department of Clinical Therapeutics (Athens, Greece). All patients had symptomatic disease, based on the IMWG criteria of that period (at least one CRAB symptom to start anti-myeloma therapy). Thirty-six (8.8%; 23M/13F) patients achieved a PFS of at least 7 years (long PFS group) after frontline treatment. The median PFS of these 36 patients is 10 years, while the other patients had a median PFS of 22 months. Long PFS patients were younger (median age 56 vs 68 years; p<0.001), had bigger body surface area (median: 1.85 m2 vs. 1.76 m2; p=0.013) and lower ECOG performance status (score 0-1: 71% vs 52%; p=0.014) compared to all others. Long PFS patients had higher hemoglobin (11.4 g/dl vs 10.2 g/dl; p=0.001), higher platelet count (278 vs 224 x109/l; p<0.001) and higher creatinine clearance (CrCl, based on the MDRD formula: 88 vs 67 ml/min; p<0.001; no patient in the long PFS group presented with CrCl <45 ml/min at diagnosis). There was no difference between the two groups regarding percentage of patients with high LDH, presence of osteolysis, type of myeloma (IgG vs IgA vs others), levels of serum and/or urine M-protein, and percentage of plasma cell infiltration in the bone marrow. However, more patients in the long PFS group had ISS-1 or ISS-2 disease (86% vs 61%; p=0.002) and normal pattern of marrow infiltration in the MRI of the spine and pelvis (24% vs 15%; p=0.035). Regarding chromosome abnormalities at diagnosis, no patient in the long PFS group had high-risk cytogenetics (defined as presence of del17p, t(4;14) or t(14;16) vs 32% in all other patients. All patients received either conventional chemotherapy (CC) or first-generation novel anti-myeloma agent (bortezomib (B), thalidomide (T) or lenalidomide (R)-based regimens as frontline therapy. There was no difference between the two groups regarding CC versus novel agent-based induction treatment. Out of 36 long-term PFS patients, 11 (30%) received CC, 8 (22%) B-based, 8 (22%) RD, 6 (17%) T-based, and 3 (8%) VTD; 10 (28%) patients received first-line therapy participating in a clinical trial. Long PFS patients had received more often autologous stem cell transplantation (ASCT, 61% vs 23%; p=0.001) as part of first line therapy; therefore, more long PFS patients had also received consolidation and/or maintenance (50% vs 15%; p=0.001). Higher proportion of patients achieved at least VGPR (74% vs 41%) or at least CR (32% vs 18%) in the long PFS group. We performed next generation flow cytometry in 23 patients of the long PFS group to evaluate minimal residual disease (MRD) and 14 (61%) of them were MRD (-) at the level of the 10-6. The probability of achieving long PFS (≥7 years) for patients who managed to be progression-free at 2, 3 and 4 years was 11.6%, 13.2% and 15.3%, respectively. In the multivariate analysis, only younger age was associated with probability for long PFS (p<0.001). The median OS of the whole group of patients was 5 years; in the long-PFS group median OS has not been reached yet while in all other patients the median OS was 4.3 years. In conclusion, our study in an unselected group of patients, the majority of whom did not participate in clinical trials, showed that 9% of patients with newly diagnosed myeloma experience prolonged PFS of more than 7 years (median: 10 years) even in the era of CC or first-generation novel agents. These patients have low risk disease, mainly of ISS-1 or -2, no high-risk cytogenetics, no or mild renal impairment, and achieve deep responses after ASCT. These patients may be considered as "functionally" cured. The incorporation of novel treatment approaches may lead to a significant improvement in the probability of achievement of this "functionally" cured status.

Abstract Purpose: We assessed the survival outcome of patients with anaplastic large cell lymphoma (ALCL) who experienced disease progression or relapse after first line and subsequent therapy. We sought to evaluate the impact of brentuximab vedotin (BV), and survival outcome of patients with ALCL who experienced progression after BV. Patients and Methods: A total of 176 patients (74 ALK+, 102 ALK-) initially diagnosed between 1999 and 2014 were retrospectively analyzed. Progression-free survival (PFS) and overall survival (OS) after the progression/relapse following first-line chemotherapy (PFS1 and OS1), after first salvage therapy (PFS2 and OS2) and after second salvage therapy (PFS3 and OS3) were calculated. Outcome was separately analyzed according to the ALK status focusing on the use of BV. Results: The median age of the patients was 50 (range: 18-89). With a median follow up of 64 months, 111 patients (38 ALK+, 73 ALK-) experienced progression/relapse after the first-line therapy, of which 4 ALK- patients were post upfront stem cell transplant (SCT). Thirty and 15 patients eventually underwent autologous and allogeneic SCT after salvage chemotherapy, respectively. The median PFS1 and OS1 in patients with ALK+ALCL and ALK-ALCL were 8.4 and 28.5 months, and 13.1 and 47.7 months, respectively. In patients with ALK+ALCL, the median PFS1, PFS2 and PFS3 were 53.6, 5.2 and 2.3 months, respectively. The median OS1, OS2 and OS3 were not reached, 47.3 and 6.1 months, respectively. In patients with ALK-ALCL, the median PFS1, PFS2 and PFS3 were 12.9, 3.0 and 2.0 months, respectively. The median OS1, OS2 and OS3 were 54.3, 10.8 and 5.8 months, respectively. Interestingly, there were no significant difference in PFS2 between ALK+ALCL and ALK-ALCL. However, OS2 was significantly longer in patients with ALK+ALCL, suggesting possibly continued chemosensitivity of recurrent ALK+ALCL. A total of 30 patients received BV in 1st salvage (15 patients) and after 2nd salvage (15 patients).The use of BV at 1st salvage was associated with significantly longer PFS2 and OS2 both in patients with ALK-ALCL but not with ALK+ALCL likely due to small number of cases. Mutivariate analysis adjusting baseline PIT risk factors and the duration of the response to first line therapy revealed that use of BV (at any point in the salvage setting) is significantly associated with longer OS2 (HR: 0.43, 95%CI: 0.23-0.80). Overall, 12 patients experienced relapse/progression after BV treatment. The median OS after BV failure was 1.4 months (95%CI: 0.5-9.5 months) (Figure). Summary: Survival outcome for relapsed/refractory patients with ALK+ and ALK- patients is improved with BV. However, survival outcome after BV failure is very poor. A new treatment strategies to consolidate or maintain the response after BV and to develop more safe and better therapeutic options are needed. Figure 1. Figure 1.

Abstract Abstract 2864 Introduction: Clinical trials have illuminated a number of unique treatment strategies for patients with CLL. The impact of these strategies on routine practice remains unknown as trial participants may not reflect the same population encountered outside of a clinical trial setting. Many questions remain regarding the sequencing of therapies based on age and performance status. By characterizing current patterns of care; patients, treating physicians, and regulatory agencies will be able to understand the current landscape of CLL treatment. The Connect® CLL registry was designed to report the natural history and real world management of patients receiving therapy for CLL. In this first report, we characterize the therapeutic approaches used for the treatment of patients with CLL of different age groups (i.e. < 65 years, 65–75 years, and ≥ 75 years) and with an ECOG PS status score of 0 compared to 1 or greater. Methods: Connect® CLL is a prospective, longitudinal, observational, multi-center registry conducted in community and academic research centers in the United States. At present, 237 sites are actively participating with a projected study enrollment of 1500 patients. Eligible patients are to be enrolled within 2 months of being initiated on any line of therapy; whether initial therapy or salvage therapy. Each patient will be followed for up to 60 months. Clinical data, physician choices, patient-reported health-related quality of life, response and survival are to be collected approximately every 3 months during participation. Results: A total of 607 patients have been enrolled (4% from academic sites) with a median age of 70 years. 198 were < 65 years old (age group 1), 187 were between 65–75 years old (age group 2), and 222 were ≥ 75 years old (age group 3). ECOG status varied across the three age groups, with an ECOG status score of ≥ 1 for 39%, 52%, and 70% of patients respectively. Treatment patterns varied across the age groups and by ECOG status in the 496 patients reporting therapies. The most commonly recorded first-line regimens independent of age included fludarabine (F) cyclophosphamide (C) and rituximab (R) (33%), bendamustine (B) +/− R (19%), F +/− R (15%), or investigational therapy (15%). For second-line regimens and beyond, the most frequently recorded regimen was B +/− R (30%), FCR (23%), other F-based regimens (13%), or investigational therapy (8%). The use of FCR for first-line treatment decreased significantly with increasing age group, (45%, 32%, 20%, for age group 1, 2, 3 respectively, p=0.04, spearman correlation) while use of F +/− R remained level across the age groups (14%, 15%, 15%, respectively). Compared to age group 1, first-line therapy with B +/− R in age groups 2 and 3 (15%, 22%, 21%, respectively) was higher but did not achieve statistical significance. B +/− R represented the most common treatment for all age groups (37%, 26%, 29%, respectively) as second line therapy but did not vary by age (P=0.35). The use of chlorambucil was infrequent in all age groups, but was more common in age group 3 patients compared to the others (P=0.01), in both first-line (2%, 4%, 12%, respectively) and subsequent lines of therapy (0%, 1%, 8%, respectively). Treatment assignments did not vary by ECOG PS score for patients in age group 1. First-line therapy for patients with an ECOG PS score of 0 in age groups 2 and 3 consisted of FCR (32% and 15%, respectively), F +/− R (19% and 15%, respectively), B +/− R (16% and 15%, respectively), and alkylating agents (3% and 23%, respectively). Patients in age groups 2 and 3 with ECOG PS score ≥ 1 received B +/− R regimen (33% and 22%, respectively), FCR (23% and 21%, respectively), F +/− R (14% and 10%, respectively) and alkylating agents (7% and 9%, respectively) as first-line therapy. Further description and clarification on the various treatment regimens based on the three age groups and by ECOG PS score will be presented at the meeting. Conclusion: The Connect® CLL Registry is the largest prospective, multicenter registry in the United States evaluating management for patients with CLL. With the currently available data, we characterize the extent to which age and performance status are associated with treatment selection in both first-line and subsequent lines of therapy in routine practice. As enrollment increases and additional follow-up is completed, the data will provide more extensive and real world overview of the current treatment strategies used in CLL patients.

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.

Abstract Abstract 3926 Introduction. Chronic lymphocytic leukemia (CLL) patients will have significant variation in signs and symptoms at initial presentation and across lines of therapy, with concomitant effect on patient health-related quality of life (HRQOL). HRQOL and other patient-reported outcomes, together with clinical outcomes, provide a more complete perspective on the burden of disease and facilitate a broader view of the impact of treatment regimens. This analysis evaluates whether the HRQOL of patients with CLL in the United States (US) varies at the time the patients are about to embark on various lines of therapy, and offers a baseline report from which subsequent longitudinal analysis post-treatment will be possible. Methods. Clinical and HRQOL data were collected in Connect®CLL, a prospective observational registry initiated in March 2010 involving centers in the US. Physicians provided data on the demographics and clinical characteristics of patients receiving therapy. HRQOL was self-reported by patients at enrollment using the Brief Fatigue Inventory (BFI, a symptom assessment tool), the EQ-5D (a non-disease-specific HRQOL instrument), and the Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu, a leukemia-specific HRQOL instrument). We characterized patients who had initial (First Line), second (Second Line) or subsequent (Higher Line) treatment regimens prior to initiation of regimens. Reported mean overall and/or domain-specific BFI, EQ-5D and FACT-Leu scores were analyzed by line of therapy. Statistical significance of score differences among sub-cohorts was ascertained by ANOVA using SAS 9.1. Results. Evaluable data were reported on 1005 patients, enrolled from 161 centers (93% community, 7% academic). Patients were predominantly male (62%) and white (89%) with mean age at 69 (standard deviation [SD] 11) years. HRQOL scores by line of therapy are presented: The total FACT-Leu and FACT-G results, and the total EQ-5D Index and Visual Analogue Scale (VAS) results, consistently suggest that patients initiating first line therapy have somewhat better HRQOL compared with those initiating subsequent lines of therapy. FACT-Leu total scores of patients initiating first line therapy were associated with better physical and leukemia-specific considerations, and the EQ-5D total score was associated with better mobility and pain/discomfort. Conclusions. Initial results from the Connect® CLL Registry indicate that HRQOL prior to treatment is better among patients initiating first line therapy compared to patients initiating later lines of treatment. Future analyses should be conducted to determine what clinical or other factors may be associated with the HRQOL deterioration in patients initiating subsequent lines of therapy, so as to inform clinician decision making. Also, subsequent longitudinal analyses should be undertaken to determine how HRQOL might be affected by the different lines of therapy and the specific treatment regimens, as well as by their initial HRQOL and other patient factors.

Abstract Introduction:In amyloid light chain (AL) amyloidosis, the most common form of systemic amyloidosis, misfolded light chain (LC) or a fragment of an LC produced by clonal plasma cells accumulates in tissue, resulting in the dysfunction of vital organs and systems (eg, heart, kidneys, nervous system). Current therapies used to treat AL amyloidosis limit LC production but do not directly target deposits underlying multiorgan failure. Approximately 75% of patients do not achieve organ responses and have persistent organ dysfunction. Amyloid-directed therapies may stabilize and potentially reverse organ damage by specifically targeting existing LC aggregates. NEOD001, a monoclonal antibody, targets misfolded LC and is thought to neutralize circulating LC aggregates and to clear insoluble deposits. We have previously reported that monthly infusions of NEOD001 were safe and well tolerated. In addition, NEOD001 was associated with renal and cardiac responses. Here we analyzed the association between organ response and depth and time since last plasma cell-directed (PCD) treatment in the entire cohort of 69 patients enrolled in both the dose-escalation and the expansion phases of the phase 1/2 study. Methods: Inclusion criteria for this trial were that patients complete ≥1 PCD treatment before enrollment, attain partial hematologic response (HR) or better to any previous therapy, and have persistent organ dysfunction. NEOD001 was administered intravenously every 28 days. During the dose-escalation phase, 27 patients received NEOD001 at 0.5, 1, 2, 4, 8, 16, or 24 mg/kg in a 3+3 study design. An additional 42 patients with renal, cardiac, or nerve involvement were enrolled and treated (24 mg/kg) in the expansion phase. We assessed cardiac and renal responses based on consensus criteria and neuropathy responses using the Neuropathy Impairment Score-Lower Limb (NIS-LL). For this analysis, we focused on the relationship between organ response after treatment with NEOD001 to the time since last or best HR and the depth of best and last HR. Results: A total of 69 patients were enrolled, 27 in the dose-escalation and 42 in the expansion cohorts. The entire population included 36 cardiac-evaluable patients, 35 renal-evaluable patients, and 11 patients evaluated for peripheral neuropathy; 39% were women, and the median age was 60 years. Time since diagnosis was 2.8 (0.4-12.8; median, range) years, and 45% of patients had undergone ≥3 previous PCD regimens. Of the patients evaluable for organ response, best response rates indicating organ response were observed in 53% of cardiac-evaluable patients (n = 19/36) and 63% of renal-evaluable patients (n = 22/35). NIS-LL scores indicated that 82% (n = 9/11) of patients met criteria for a peripheral neuropathy response to NEOD001. Cardiac and renal response rates for NEOD001-treated patients could not be attributed to previous PCD treatment regimens. For example, 37% of the NEOD001 cardiac responders and 35% of nonresponders received cyclophosphamide-bortezomib-dexamethasone. Similarly, for NEOD001 renal responders vs nonresponders, 27% vs 25% were treated with autologous stem cell transplantation and 27% vs 31% were treated with bortezomib-dexamethasone. There was no relationship between NEOD001 cardiac, renal, or peripheral nerve organ response and time since last chemotherapy, time since last or best HR, or depth of last or best HR. Finally, an equivalent percentage of evaluable patients experienced renal or cardiac response regardless of whether they had received their most recent PCD treatment ≤6 months or >6 months before NEOD001 initiation. The median time since last PCD treatment to the start of NEOD001 intervention for all patients was 6.5 (range, 0.6-85.8) months and the median time to first cardiac response after NEOD001 treatment for all cardiac responders was 2 months. NEOD001 treatment was safe and well tolerated. Conclusions: Patients treated with monthly NEOD001 infusions had high organ response rates that were independent of time since previous chemotherapy, depth of hematologic response, or predominant type of PCD treatment. Ongoing studies of NEOD001 include VITAL (phase 3 in patients with newly diagnosed AL amyloidosis) and PRONTO (phase 2b in previously treated AL amyloidosis patients with persistent cardiac dysfunction).

Abstract Objective. SPIRIT 2 is the largest phase 3 prospective randomized open-label trial comparing imatinib (I) 400mg with dasatinib (D) 100mg daily in newly diagnosed chronic phase CML. The primary endpoint was 5 year event-free survival. Methods. 812 (406 in each arm) of 814 patients recruited started study medication (median age 53.2, 275/812 (33.8%) were over 60 years old). Patients were recruited at 144 hospitals between August 2008 and March 2013 and randomized to receive either imatinib 400mg or dasatinib 100mg daily. Secondary endpoints included overall survival, rates of treatment failure, cytogenetic/molecular response - RT-PCR BCR-ABL/ABL ratio of <0.1%IS(major molecular response (MMR), 3 log reduction, MR3) and deeper. To address the potential confounding effect on the primary endpoint of patients switching from randomized treatment to an alternative TKI or other treatment, exploratory per-protocol analyses were performed using the inverse probability of censoring weighting (IPCW) method.Results. All patients have now completed 5 years of follow-up. 424/812 (52.2%) patients completed the study whilst still taking first line medication: 230/406 (56.7%) on dasatinib, 194/406 (47.8%) on imatinib. Of the patients who discontinued first line therapy, more patients on the imatinib arm switched due to suboptimal PCR response (as decided by the local investigator) than on dasatinib (D7/406, 1.7%; I71/406, 17.4%) but more patients on the dasatinib arm discontinued due to intolerance (D123/406, 30.3%; I68/406, 16.7%). More patients went on to transplant in the imatinib arm than in the dasatinib arm (D 6/406, 1.5%; I 30/406 7.6%) and in the imatinib patients undergoing transplant the reason for first line treatment failure was disease progression in 5/30 and suboptimal molecular response in 11/30. Using an intention to treat analysis cumulative incidence of MR3 and MR4 on first line therapy within 5 years was higher in the dasatinib arm than the imatinib arm (MR3: D 83.0%, I 63.0% - difference 20.0%, p<0.0001; MR4: D 77.5%, I 57.2% - difference 20.3%, p<0.0001).At 24 months the complete cytogenetic response rate was D 42.6%, I 31.8% - difference 10.8%, Chi-square test p=0.001.At 5 years the probability of treatment failure-free survival was higher with dasatinib than imatinib(D60.9%, I52.9% - HR: 0.73 (95%-CI:0.59-0.90), p=0.004) but there were no significant differences in event free survival (D91.0%, I89.0% - HR:0.80 (95%-CI:0.51-1.25), p=0.319) or overall survival (D91.9%, I91.2% - HR: 0.90 (95%-CI:0.56-1.47), p=0.690). IPCW modelling results will be presented at the meeting.The overall rate of pleural effusion over 5 years in the dasatinib arm was 36.0% with a higher incidence in older patients. 13 patients developed their first pleural effusion after 3 years on study. Conclusions. In SPIRIT 2 we observed a higher molecular and cytogenetic response rate and also a higher pleural effusion rate with dasatinib but a higher treatment failure rate with imatinib often because investigators were concerned about sub-optimal PCR responses. More imatinib-treated patients proceeded to transplant. There were no statistically significant differences in event free survival (the primary endpoint) or overall survival. Imatinib remains a highly effective first line therapy though subgroup analyses are planned to explore whether dasatinib may have advantages in particular clinical scenarios.
