Background Essential thrombocythemia (ET) is a myeloproliferative neoplasm (MPN) associated with an increased risk of thrombotic events (TEs), which represent a substantial cause of mortality in this population. There is limited contemporary, real-world evidence exploring the effect of TEs on mortality in patients with ET. The aim of this analysis was to compare risk of mortality among patients newly diagnosed with intermediate- or high-risk ET who experienced a TE vs those who did not experience a TE. Study Design and Methods All data from the Medicare Fee-for-Service (FFS) claims database (Parts A/B/D) from January 2010-December 2017 were used to identify patients with an ET diagnosis (all intermediate or high risk based on cohort age ≥65 years) with ≥1 inpatient or ≥2 outpatient claims. The index date was the date of the first qualifying ET claim. Patients with an ET diagnosis, use of hydroxyurea, or use of ruxolitinib within 12 months before the index date and patients with a myelofibrosis diagnosis during the study period were excluded. A minimum of 12 months of continuous medical and pharmacy enrollment pre-index was required. The study sample was categorized into TE and non-TE groups based on the occurrence of any of the following events during follow-up: deep vein thrombosis, pulmonary embolism, ischemic stroke, acute myocardial infarction, transient ischemic attack, peripheral arterial thrombosis, or superficial thrombophlebitis. TEs were evaluated from the index date to the end of follow-up. Cox regression analyses with time-varying effects were used to assess mortality risk among patients with ET with post-index TE as a time-dependent variable, stratified by pre-index TE, and adjusting for patient demographic characteristics and comorbid conditions. Results A total of 143,588 Medicare FFS beneficiaries with a diagnosis of ET met the study inclusion criteria; median age was 76.0 years, 68.1% were female, and 84.2% were white. Pre-index TE was reported in 37,284 patients (26.0%). In the follow-up period, 49,497 patients (34.5%) had a TE and 94,091 patients (65.5%) did not have a TE. In the comparison between the TE vs non-TE groups, the median (range) age (77 [65-107] vs 75 [65-110] years, respectively), mean (SD) Charlson comorbidity index score (4.8 [3.5] vs 3.8 [3.5]), and percentage of patients with a history of bleeding (27.0% vs 22.2%), anemia (64.7% vs 55.9%), or a cardiovascular event (45.8% vs 33.5%) were higher (Table 1). The median time from ET diagnosis to first TE in the follow-up period was 2.8 months for all patients, 0.5 months for patients with pre-index TE, and 8.0 months for those without pre-index TE. The most common types of first TE in the follow-up period were ischemic stroke (37.3%), acute myocardial infarction (23.2%), and transient ischemic attack (22.6%). The risk of mortality was increased for patients who experienced a TE compared with those who did not (hazard ratio [HR; 95% CI], 11.2 [10.6-11.8]; P<0.001), including for both those with pre-index TE (HR [95% CI], 9.3 [8.6-10.1]; P<0.001) and those without pre-index TE (HR [95% CI], 15.4 [14.2-16.8]; P<0.001). Conclusions In this contemporary, real-world analysis, approximately one-third of patients with newly diagnosed intermediate- to high-risk ET experienced a TE. Elderly patients with ET who experienced a TE had an approximately 11-fold increased risk of mortality vs those who did not experience a TE, highlighting a continued unmet need in this population. Further efforts are needed to better define and mitigate TE risk in patients with ET, particularly in those with prior TE.

Background Polycythemia vera (PV) is a myeloproliferative neoplasm (MPN) associated with an increased risk of thrombotic events (TEs), a major cause of morbidity and mortality. Patients aged ≥60 years and/or with a history of thrombosis are considered to have high-risk PV. There is limited contemporary, real-world evidence exploring the effect of TEs on mortality in patients with PV. The aim of this analysis was to compare the risk of mortality in patients newly diagnosed with high-risk PV who experienced a TE vs those who did not experience a TE. Study Design and Methods All data from the Medicare Fee-for-Service (FFS) claims database (Parts A/B/D) from January 2010-December 2017 were used to identify patients with a PV diagnosis (all high risk based on cohort being ≥65 years of age) with ≥1 inpatient or ≥2 outpatient claims. The index date was the date of the first qualifying PV claim. Patients with a PV diagnosis or use of cytoreductive therapy within 12 months before the index date (pre-index period) were excluded; ≥12-months continuous medical and pharmacy enrollment pre-index dates was required. The study sample was categorized into TE and non-TE groups based on the occurrence of any of the following events during follow-up: deep vein thrombosis, pulmonary embolism, ischemic stroke, acute myocardial infarction, transient ischemic attack, peripheral arterial thrombosis, or superficial thrombophlebitis. TEs were evaluated from the index date to the end of follow-up. Cox regression analyses with time-varying effects were used to assess mortality risk among patients with PV, with post-index TE as a time-dependent variable, stratified by pre-index TE, and adjusting for patient demographic characteristics and comorbid conditions. Results A total of 56,176 Medicare FFS beneficiaries with PV diagnoses met inclusion criteria. The median age was 73 years, 51.9% were men, and 90.7% were white; 10,110 patients (18.0%) had a history of TE before diagnosis (ie, pre-index). In the follow-up period, 20,105 patients (35.8%) had a TE and 36,071 patients (64.2%) did not have a TE. In the comparison between the TE vs non-TE groups, the median (range) age (75.0 [65-104] vs 73.0 [65-106] years, respectively), mean (SD) Charlson comorbidity index score (3.1 [2.6] vs 2.2 [2.3]), and percentage of patients with a history of cardiovascular events (34.1% vs 23.8%), bleeding (13.3% vs 10.4%), or anemia (28.6% vs 23.4%) were higher (Table 1). Among all patients with PV, the median time from diagnosis to first post-index TE was 7.5 months. Among those with pre-index TE (n=10,093), median time from index to first post-index TE was 0.6 months, whereas patients without pre-index TE (n=46,083) had a median time to first post-index TE of 14.2 months. Among all patients with TE during follow-up, the most common TEs were ischemic stroke (47.5%), transient ischemic attack (30.9%), and acute myocardial infarction (30.5%). The risk of mortality was increased for patients who experienced a TE compared with those who did not (hazard ratio [HR; 95% CI], 9.3 [8.4-10.2]; P<0.0001). For patients who experienced a pre-index TE, the risk of mortality was increased for patients who experienced a subsequent TE during follow-up compared with patients who did not (HR [95% CI], 6.7 [5.8-7.8]; P<0.0001). Likewise, for patients who did not experience a pre-index TE, the risk of mortality was increased for patients who experienced a TE during follow-up compared with patients who did not (HR [95% CI], 13.1 [11.4-15.0]; P<0.0001). Conclusions In this real-world study, approximately one-third of patients with newly diagnosed high-risk PV experienced a TE during follow-up and had a 9-fold increased risk of mortality vs those who did not experience a TE. TE risk mitigation remains an important management goal in patients with PV, particularly in those with prior TE.

Background The myeloproliferative neoplasm myelofibrosis (MF) is associated with reduced overall survival (OS) compared with the general population (Hultcrantz M, et al. J Clin Oncol. 2012;30[24]:2995-3001; Price GL, et al. PLoS One. 2014;9[3]:e90299). The Janus kinase 1 and 2 inhibitor ruxolitinib (RUX) was approved by the US Food and Drug Administration in November 2011 for the treatment of adult patients with intermediate- or high-risk MF based on data from the phase 3 COMFORT trials, which showed significantly improved OS in patients who received RUX (Verstovsek S, et al. J Hematol Oncol. 2017;10:156). Understanding the clinical benefit of RUX in real-world practice requires an understanding of changes in patient outcomes for those exposed to RUX compared with those never exposed to RUX, both before and after approval. The aim of this analysis was to assess the OS of patients newly diagnosed with intermediate- to high-risk MF before RUX approval, and for those who were RUX-unexposed vs -exposed in the post-RUX approval time frame. Study Design and Methods All data from the Medicare Fee-for-Service claims database (Parts A/B/D) from January 2010 to December 2017 were used to identify patients who were ≥65 years old (intermediate-1 or higher risk MF due to age) with ≥1 inpatient claim or ≥2 outpatient claims with a documented MF diagnosis. The index date was the date of the first qualifying MF claim; ≥12 months of pre-index continuous medical and pharmacy enrollment was required. Patients with evidence of an MF diagnosis ≤12 months before the index date were excluded. Patients with a diagnosis of myelodysplastic syndrome, hematologic malignancies (leukemias, multiple myeloma, and lymphomas), or solid tumors either ≤12 months before, on, or any time after index were also excluded in a stepwise manner. The study sample was classified into 3 groups: patients diagnosed with MF pre-RUX approval (index year 2010-2011; no post-index exposure to RUX); those diagnosed with MF post-RUX approval and unexposed to RUX (index year 2012-2017); and those diagnosed with MF post-RUX approval and exposed to RUX (index year 2012-2017). One-year survival rate and risk of mortality were estimated using Kaplan-Meier and Cox proportional hazards regression analyses, adjusting for baseline demographic and clinical characteristics. OS was measured from the index date until death or end of follow-up. Patients without a death date were censored at disenrollment or the end of the study period, whichever occurred first. Results Among eligible patients with an MF diagnosis (N=1677), median age was 78 years, 39.8% were male, and 84.1% were white. The analysis included 278 patients diagnosed pre-RUX approval (all RUX-unexposed) and 1399 diagnosed post-RUX approval (RUX-unexposed, n=1127; RUX-exposed, n=272). Median follow-up for the pre- and post-RUX approval groups was 12.5 and 11.3 mo (RUX-unexposed, 10.2 mo; RUX-exposed, 14.0 mo), respectively. In the pre-RUX approval group, 119 (42.8%) patients had a valid death date compared with 436 (31.2%) in the post-RUX approval group (RUX unexposed, n=382 [33.9%]; RUX exposed, n=54 [19.9%]). The 1-year survival rate (95% CI) was 55.6% (49.4%-61.3%) for the pre-RUX approval group, 72.5% (69.5%-75.2%) for the post-RUX approval RUX-unexposed group, and 82.3% (76.7%-86.7%) for the post-RUX approval RUX-exposed group (Figure). The risk of mortality was lowest among RUX-exposed patients (adjusted hazard ratio [HR], 0.36; 95% CI, 0.26-0.50; P<0.0001 vs the pre-RUX approval group). Patients in the post-RUX approval group who had never been exposed to RUX also had a lower risk of mortality, although less pronounced than RUX-exposed patients, compared with the pre-RUX approval group (adjusted HR, 0.67; 95% CI, 0.56-0.80; P<0.0001). Conclusions In this real-world study of US patients diagnosed with intermediate- or high-risk MF, 1-year OS was improved in patients diagnosed after RUX approval compared with before RUX approval. Notably, in the post-RUX approval time frame, 1-year OS was greater for those who received RUX than for those who did not receive RUX. These findings complement the survival benefit results demonstrated in the COMFORT studies using real-world data.

Background: CPX-351 is a liposomal encapsulation of daunorubicin and cytarabine in a 1:5 molar ratio. In a randomized phase 3 study (CPX-351-301) conducted in older adults (60 to 75 years old) with newly diagnosed, high-risk and/or secondary AML, CPX-351 induction therapy was superior to standard 7+3 with improved rates of complete remission (CR) and overall survival (OS). In both older adults and high-risk AML, allogeneic hematopoietic cell transplantation (HCT) is frequently the preferred post-remission strategy owing to the high rates of relapse and poor overall survival with conventional chemotherapy approaches. After a median follow-up of 20.7 months, the primary pre-planned analysis found that more patients randomized to CPX-351 underwent HCT and an exploratory landmark survival analysis from the time of HCT favored CPX-351 (HR = 0.46 [95% CI: 0.24, 0.89]; one-sided P = 0.009). However, the initial protocol did not collect data related to HCT and the basis for improved HCT outcomes with CPX-351 was previously unknown. Here we present a detailed analysis of HCT outcomes in patients enrolled in the CPX-351-301 study with 5-years of follow-up. Methods: Patients age 60 to 75 years with high-risk and/or secondary AML were randomized in a 1:1 fashion to receive CPX-351 or 7+3 as induction and consolidation chemotherapy (Lancet J et al, JCO 2018). The protocol was amended to collect additional HCT-specific information, including donor and HCT characteristics and post-HCT outcomes, including rates of relapse and GVHD. Post-HCT outcomes including relapse, GVHD, and death were analyzed as competing events. Results: Of 309 randomized patients in the CPX-351-301 study, more patients achieved CR/CRi with CPX-351 vs 7+3 (48% vs 33%) allowing more patients to proceed to HCT (35% vs 25%) and more patients to proceed to HCT in remission (CPX-351: 41/73 [56%]; 7+3: 24/52 [46%]). The median age was 66 years with CPX-351 vs 65 years with standard induction among the transplanted cohorts; 16 patients in the CPX-351 transplanted arm were over the age of 70 compared to only 6 in the 7+3 arm. Other pre-HCT patient characteristics were balanced between the CPX-351 and 7+3 groups, including ECOG performance status (8% vs 5% with ECOG PS of 2), HCT-CI (median 4 vs 3), donor type (matched unrelated donor 49% vs 49%), and conditioning regimen intensity (myeloablative [17% vs 13%] vs reduced-intensity conditioning [43% vs 46%]). The Kaplan-Meier-estimated 3-year survival rate among transplanted patients was 56% with CPX-351 vs 23% with 7+3 (Figure 1A). The differences in survival consistently favored CPX-351 across patient age, AML subtype, disease status, donor type, and conditioning intensity (Figure 1B). Differences in OS were driven by a large reduction in non-relapse mortality (HR = 0.42 [95% CI: 0.21, 0.86]; Figure 1D). The cumulative incidence of acute GVHD with death as a competing event at 6 months from HCT date was 0.49 (95% CI: 0.35, 0.62) in the CPX-351 arm and 0.38 (95% CI: 0.23, 0.53) in the 7+3 arm. Conclusions: Analysis of HCT outcomes in patients enrolled in the CPX-351-301 study demonstrated that treatment with CPX-351 in older adults with high-risk and/or secondary AML resulted in more patients bridged to HCT and more patients transplanted in CR/CRi compared to 7+3, with improved OS in transplanted patients. The pattern of HCT outcomes suggests improved disease control with CPX-351 induction allowing higher HCT rates, but more importantly improved tolerability with less non-relapse mortality; this data supports the development of CPX-351 in other high-risk AML populations in which allogeneic HCT is the preferred post-remission strategy.

INTRODUCTION Adolescents and young adult (AYA) survivors of Hodgkin lymphoma (HL) are potentially at increased risk of cardiovascular (CV) disease due to anthracycline exposure, in addition to use of mediastinal radiotherapy (RT). Although the risk has been well described in the pediatric age-group, the impact in the AYA population has been less well characterized. Capturing the incidence of these late effects is challenging given that events can occur more than a decade after therapy completion. Using population-based administrative data, we evaluated the incidence of CV disease (combined heart failure (HF) and ischemic heart disease (IHD)) in a cohort of AYA survivors treated for classical HL (cHL) using ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) or equivalent chemotherapy. METHODS Patients with cHL aged 16-39 years (y), diagnosed between 1992-2013 and treated with an ABVD or equivalent therapy, were identified in the BC Cancer Lymphoid Cancer Database. Patients must have survived to an Index Date defined as 2 y from most recent HL event (primary diagnosis or if applicable, most recent relapse) and have had a minimum follow-up of 1 y beyond their Index Date. Patients were excluded if they had history of prior malignancy or HIV positivity. Limited stage disease was defined as stage IA, IB or IIA and absence of bulky disease (≥10cm); all others had advanced stage disease. Cases were linked with population-based databases of BC Cancer Registry; BC Radiation Oncology Database; and BC Ministry of Health (MOH) Chronic Disease Registry (CDR) that captures all BC residents registered with medical service plan coverage during the study period. The outcome variables, including HF and IHD, were defined by the BC MOH CDR using Standardized Case Definitions. To focus on late onset CV complications, only events that occurred after the Index Date were included in the analysis. A 10:1 individually-matched control population was identified from the CDR based on age, sex, and health authority region on the Index Date of the matched case. Controls were excluded if they had a pre-existing malignancy, HF, or IHD prior to the study window. Individual outcomes were collected from the Index Date of the matched case until December 31, 2015 or until an individual was censored due to loss to follow-up or death. Kaplan Meier (K-M) methodology and log-rank test was used to estimate cumulative incidence. A competing risk regression analysis was used to evaluate relative risk (RR) and p-values less than 0.05 were considered significant. RESULTS With a median follow-up time of 11 y (range 3-24 y) from most recent HL event, 764 AYA 2-y survivors were identified, aged 20 to 61 y (median 38 y) at the end of study period. The proportion of limited and advanced stage disease was 34.2% and 65.6%, respectively; and 49.9% were male. Eighty-eight patients (11.5%) had relapsed disease; eighty-six (11.3%) underwent high dose chemotherapy and autologous stem cell transplantation as part of their salvage therapy. In total, 268 patients (36.4%) were treated with mediastinal RT for primary therapy or for relapsed disease. Fifty-three percent received cumulative anthracycline dose ≥300 mg/m2. Survivors had a 3-fold increased risk of CV disease relative to controls (p<0.0001). The onset of CV disease in survivors occurred at median of 11.7 y after most recent treatment (range 2.2-19.2 y), and at a median age of 44.3 y (range 21 - 58 y). At 15 y, the estimated cumulative incidence of CV disease was 6.3% in survivors compared to 2.3% in controls (Figure A). In the 496 survivors that received chemotherapy only, the incidence of CV disease at 15 y was 4.6% vs 2.3% in controls, and those that received anthracyclines and mediastinal RT had significantly higher incidence at 8.6% (Figure B). The increase in risk was greatest for a diagnosis of HF (RR 6.92, p<0.0001): at 15 y, the cumulative incidence of HF was 2.2% vs 0.6% in controls. The RR of IHD was 2.63 (p<0.0001) with incidence of 5.1% in cases compared to 1.8% in controls. CONCLUSION Similar to the pediatric population, AYA cHL survivors are at increased risk of both HF and IHD after completion of treatment. The majority of patients had received ABVD alone and had a lower incidence of CV disease at 15 y when compared to those that received treatment that included mediastinal RT. These results will inform counseling regarding risk factor modification and aid in the development of surveillance guidelines for AYA survivors.

Abstract Background VMP and Rd are two of the most efficient and widely accepted regimens in the treatment of elderly newly diagnosed MM patients. In order to further improve the outcome of elderly patients, one possibility would be to use regimens including all these drugs simultaneously, but this may result into high toxicity. Alternatively, the use of these regimens (VMP and Rd) in a sequential or alternating scheme could improve the treatment of elderly patients. We hypothesized the alternating scheme would minimize the emergence of resistant clones, and would reduce the cumulative toxicity. In order to test this hypothesis we decided to compare VMP and RD in a sequential vs an alternating scheme. Patients and methods 241 patients were randomized to receive a sequential scheme consisting on 9 cycles of VMP followed by 9 cycles of Rd or the same regimens in an alternating approach (one cycle of VMP alternating with one Rd (half of the patients started by VMP and half by Rd) up to 18 cycles). VMP included the iv administration of bortezomib 1.3 mg/m2 twice weekly for 1 six-weeks cycle, followed by once weekly for 8 four-weeks cycles in combination with oral melphalan 9 mg/m2 and prednisone 60 mg/m2 once daily on days 1–4 of each cycle. Rd treatment consisted on lenalidomide 25 mg daily on days 1-21 plus dexamethasone 40 mg weekly. Results 121 patients were allocated to receive the sequential scheme and 120 the alternating regimen. Both arms were well balanced according to the baseline characteristics. 52% patients in the sequential arm and 55% in the alternating and had high risk cytogenetic abnormalities (t(4;14), t(14;16), del17p or 1q gains). After 9 cycles of treatment, in the sequential arm, 35 out of 66 (54%) achieved at least VGPR vs 51 out of 65 patients (78%) in the alternating arm (p=0.002), including sCR/CR rate of 28% vs 38% in the sequential and alternating arms, respectively (p=NS). Seven patients in each arm achieved immunophenotypic CR. Moreover, while four patients progressed in the sequential arm under treatment with VMP, no patients in the alternating scheme developed disease progression during the first 9 cycles, After a median follow up of 12 months, there was a trend for shorter TTP in the sequential as compared with the alternating scheme (18 m-TTP of 83% vs 89% (p=NS)). In terms of OS, 83% of patients in the sequential arm were alive at 18 m versus 93% in the alternating (p=NS). Patients who achieved sCR/CR had a significantly longer 18 m-TTP as compared with patients who didn’t achieve it in both sequential (100% vs 71%; p=0.006) and alternating arms (100% vs 79%; p=0.006) and this translated into a significant benefit in OS. No differences were observed in overall response rates and CR rates in standard and high risk patients. The 18 m-TTP was similar in standard and high risk groups in both sequential (86% vs 81%) and alternating arms (84% vs 94%), noting that 94% of patients receiving the alternating scheme were progression-free at 18 months. Regarding hematologic toxicity, the frequency of G3-4 neutropenia was slightly lower in the sequential than in the alternating arm (16% and 23%) and the same trend was observed for G3-4 thrombocytopenia (16% vs 20%). Concerning non-hematologic toxicity, 5% and 4% of the patients in the sequential and alternating arms developed G3-4 infections, respectively; the rate of G3-4 skin rash was 4% in the sequential and 3% in the alternating arm; 4% of patients in the sequential arm developed G3-4 peripheral neuropathy and 3% in the sequential arm. The rate of grade 3-4 thrombotic events was 2% in both arms. Nevertheless, the detailed evaluation of the toxicity will be done at the completion of the trial when all patients will have received the same amount of drugs in either a sequential or an alternating scheme (at the present time, 42 patients in the sequential arm were not yet at risk for the development of lenalidomide-related side effects). Conclusions The administration of melphalan, bortezomib, lenalidomide and steroids in elderly MM patients in a sequential or alternating scheme is feasible. Although longer follow-up is necessary, the alternating scheme may be superior in terms of response rate and outcome, as result of the early exposure of the plasma cell to different agents. Toxicity profile is acceptable. Aparently both schemes of therapy seems to overcome the poor prognosis of high risk cytogenetic. Disclosures: Mateos: Janssen, Celgene: Honoraria.

Abstract BACKGROUND: Consistent with the advanced age at diagnosis (median age ~70 years), most patients with CLL have co-existent health problems. These co-morbidities influence the ability of many CLL patients to tolerate aggressive chemotherapy-based treatment and can also contribute to treatment-related side effects. The recent development of novel signaling inhibitors, particularly the Bruton's tyrosine kinase inhibitor ibrutinib, has been a major treatment advance for patients with CLL. While these agents generally have favorable toxicity profiles relative to standard chemotherapy-based treatments, they are chronic therapies which patients typically stay on for an extended period. Preliminary data suggests ibrutinib may be associated with an increased risk of atrial fibrillation (Afib). In one randomized trial comparing ibrutinib to ofatumumab in patient with relapsed CLL, incident grade 3+ Afib occurred in 3% of ibrutinib treated patients compared to 0% of ofatumumab treated patients (NEJM 371:213). Despite these observations, the baseline frequency of Afib in patients with CLL is not well described - particularly incident atrial fibrillation acquired during the course of the disease. METHODS: We used the Mayo Clinic CLL database to evaluate the prevalence of Afib at the time of CLL diagnosis as well as the incidence of Afib during follow-up. All patients with a new diagnosis of CLL after January 1995 who were seen at Mayo within 12 months of diagnosis were included in the analysis. Afib was identified by chart review and by billing search using ICD9 codes. Data on co-morbid conditions associated with risk of Afib was also abstracted (e.g. hypertension, coronary artery disease [CAD], valvular heart disease, cardiomyopathy, diabetes mellitus, pulmonary disease). RESULTS: A total of 2444 patients with newly diagnosed and previously untreated CLL were seen at Mayo Clinic within 12 months of diagnosis between 1/1995 and 4/2015.Median age at diagnosis was 65 years and 1626 (66.5%) patients were men. A history of Afib was present at the time of CLL diagnosis in 148 (6.1%) patients. Four additional patients had Afib documented in the record but the precise date of onset (e.g. prior to or after CLL diagnosis date) could not be determined. Age, male sex and history of CAD, valvular heart disease, cardiomyopathy, hypertension, and diabetes were associated with a greater likelihood of having a history of Afib at the time of CLL diagnosis (all p<0.01). Among the 2292 patients without a history of Afib at CLL diagnosis, 139 (6.1%) had incident Afib during the course of follow-up for their CLL. The incidence of Afib among patients without a history of Afib at diagnosis was approximately 1%/year (Figure 1A). Considering both Afib present at the time of CLL diagnosis or acquired during the course of the disease, 291 (11.9%) of the 2444 patients in this cohort experienced Afib (median follow-up: 59 months). Among patients without Afib at the time of CLL diagnosis, the following characteristics at the time of CLL diagnosis were associated with an increased risk of incident Afib on multivariate analysis: older age (age 65-74 HR=2.4, p<0.001; age ≥75 HR=3.6, p<0.001), male sex (HR=1.8, p=0.004); valvular heart disease (HR=2.4, p=0.007), and hypertension (HR=1.5; p=0.02). A predictive model for acquired Afib was subsequently constructed based on the independent factors in the Cox regression model. An individual weighted risk score was assigned to each independent factor based on the regression coefficients of the HRs. The Afib risk score (range 0-7) was defined as the sum of the scores of these independent factors. The risk of incident Afib among patients with risk scores of 0-1, 2-3, 4, and 5+ is shown in Figure 1B. Rates for these 4 groups were significantly different (p<0.001), with the 10-year Afib rates (95% C.I.) for those with a score of 0-1, 2-3, 4, and 5+: 4% (2-6%), 9% (6-13%), 17% (11-23%), and 33% (20-43%), respectively. CONCLUSIONS: A history of Afib is present in approximately 1 out of every 16 patients with newly diagnosed CLL. Among patients without Afib at diagnosis, the incidence rate of Afib is ~1%/year. The risk of incident Afib in newly diagnosed CLL patients can be predicted based on age, sex, and co-morbid health conditions present at diagnosis. These data provide context to help interpret data on the frequency of Afib in CLL patients treated with ibrutinib and other novel agents.

Multiple Myeloma is preceded by precursor states of monoclonal gammopathy of undermined significance (MGUS) and smoldering multiple myeloma (SMM). Studies have shown that progression to symptomatic MM five years after diagnosis is 1% for MGUS and 10% for SMM. However, based on the genomic background, this rate is highly variable, especially for SMM patients. Recent studies have evaluated the high-risk genomic features for SMM, but the genomic background of SMM patients who do not progress to MM after long-term follow-up (>= 5 years) has not been described. Here, we evaluated genomic changes enriched in non-progressor (NP) (no progression after 5 years of follow-up) precursor conditions (N=31) with those progressed within a short time (N=71) as well as newly diagnosed Myeloma (N=192). We also studied additional unique samples from 18 patients at their precursor stage as well as when progressed to Myeloma. We report a similar large-scale CN alteration in non-progressor SMM compared to progressor SMMs or MM at diagnosis. However, whole-genome sequencing data showed that the overall mutational load for non-progressor SMM samples was lower than Progressor MGUS/SMM (median SNV 5460 vs. 7018). This difference significantly increased for mutations affecting the coding regions. NP samples at diagnosis had 26% and 53% less coding mutations (missense, nonsense, and frameshift mutations) compared to progressor MGUS/SMM (p=0.008) and newly diagnosed MM (p < 0.001) respectively. We observed very low NRAS (3%, OR=8.86) and BRAF (3%, OR=2.17), mutation frequency in non-progressor SMM samples compared to newly diagnosed MM. We did not observe driver mutations in FAM46C, TTN, CYLD, TP53, KMT2C, IRF4, HIST1H1E that are otherwise frequently mutated in high-risk SMM or symptomatic MM. None of the non-progressor SMM samples had MYC alteration. We observed t(11;14), t(4;14), and t(14;16) translocations at similar frequency compared to newly diagnosed MM samples. We also observed a significant difference in non-recurrent focal deletions. Based on our recent data in newly-diagnosed MM, we quantified genomic scar score, and observed that non-progressor SMM have lower GSS (median=3,IQR=[1-9]) compared to progressor MGUS/SMM (median=11,IQR=[5-15] / median=9,IQR=[9-15], respectively) as well as MM samples at diagnosis (median=9, IQR= [5-16],p=0.002). We further validated this observation in an independent cohort with 69 SMM samples in whom progressor SMM patients had high GSS (median =4, IQR=[2-7.75]), compared to delayed progressor (> four years) or non-progressor SMM (median =1.5, IQR= [0-3.5]; p=0.029). Moreover, non-progressor SMM had significantly low utilization of APOBEC and DNA repair mutational processes. Next, we compared non- progressor SMM with progressor SMM using RNAseq data. We identified 1653 differentially expressed genes (DEG) (762 up-regulated and 891 down-regulated). Genes that were upregulated in non-progressor SMM samples were enriched in IL6/JAK/STAT3 and IL2/STAT5 signaling and the regulation of cytokine secretion. Whereas genes up-regulated in progressor SMM were enriched in MYC targets, DNA repair, and mTOR pathways. Moreover, genes that control the translational initiation, translational elongation, mitochondrial translation, and ATP control were among the top highly expressed genes in progressor SMM. We used our MGUS/SMM to MM paired samples and showed that the E2F target, MYC target, and G2/M checkpoint pathways are more active at MM. We measured the distance between progressor and non-progressor SMM as well as MM and found that non-progressor SMM is less similar to MM compared to progressor SMM. In conclusion, the global CNA and translocations are similar between progressor and non-progressor SMM and symptomatic MM and confirm their role in the development of precursor condition but not adequate for progression to MM, which requires additional hits. On the other hand, lower GSS score reflecting genomic stability along with lower SNVs, low DNA damage and APOBEC mutational processes, down-regulated MYC target genes, and low DNA repair activation define low-risk SMM. These results now provide the basis to develop a genomic definition of SMM. Disclosures Fulciniti: NIH: Research Funding.

Introduction: The JAK1/2 inhibitor, ruxolitinib, was approved in the USA in 2011 for the treatment of patients with myelofibrosis (MF) with intermediate and high-risk IPSS score (International Prognostic Scoring System). In the approval phase 3 COMFORT 1 - 2 studies, about 50% patients were taking ruxolitinib for at least 3 years, respectively. Objective: We sought to evaluate the characteristics and outcome of MF patients on long-term ruxolitinib therapy (≥3 years) at our center. Methods: We retrospectively reviewed the charts of patients with MF who were treated with ruxolitinib for ≥3 years. Cytogenetic were classified into risks according to Gangat et all, JCO, 2011. Descriptive statistics were used for nominal and continues variables, captured at the time of ruxolitinib start. Duration of therapy and overall survival (OS) were estimated using the Kaplan-Meier method, from the start of ruxolitinib initiation until the last day of initial ruxolitinib therapy, the date of last follow-up or death, respectively. Response to therapy was according to IWG-MRT 2013 criteria. Results: Among 437 patients who initiated therapy with ruxolitinib at our center, 136 (31%) remained on therapy for ≥3 years and represent current cohort. Ninety-one patients (67%) were newly diagnosed; the remaining patients presented after a median of 28 months (range, 4-228) from MF diagnosis. Median time to initiate ruxolitinib from presentation to our center was 1 month (range, 0.3-123) for all patients. However, the time was longer for patients who presented > 3 months from MF diagnosis (median of 11.5 months; range, 3.5-123). Patient's characteristics (n = 136) at the time of ruxolitinib initiation are summarized in Table 1. Median age was 67 years (range, 32-84), and 76 (56%) of patients were males. Half of the patients had high risk IPSS score, > 80% had systemic symptoms or splenomegaly. Eighty six percent of patients had diploid or favorable karyotype. JAK2 mutation was detected in 87% of tested patients. Median duration of ruxolitinib therapy was 72 months (95% CI: 66-78). Over the median follow-up of 83 months (range, 36-174), 63 patients (46%) died. Currently, 48 (35%) patients are still on ruxolitinib; 88 discontinued therapy after a median time of 55 months (range, 47-63). By 5th and 7th year of therapy, out of 136 patients that were treated for at least 3 years, 35% and 65% percent of patients discontinued treatment. The reasons for discontinuation included allogeneic stem cell transplantation (SCT, n 5), cytopenia (n 6), progression of MF (n 38), progression to accelerate phase (n 2) or acute leukemia (n 7), patient's choice (n 11), and death (n 23: infection 4, cardiac 3, cancer 3, others 16). Overall, 101 patients (74%) achieved IWG-MRT response, represented in majority by clinical improvement (CI) in spleen (n 90, 84%) and CI in TSS (n 51, 71%), respectively. The remaining patients achieved clinical benefit not qualifying for overall IWG-MRT response. Median duration of IWG-MRT response was 55 months (95% CI: 48-63). Responses were ongoing in 29 patients (29% of initial responders) at the time of last follow-up. Median duration of therapy was 75 months (95% CI: 68-82) for responders vs 60 months (95% CI: 39-79) for non-responders, p = 0.74. Median OS from the start of ruxolitinib was 90 months (95% CI: 76-104), Figure 1. Median OS for patients who were on ruxolitinib for ≥5 years (n = 73) was 106 months (95% CI: 80-137). Univariate and multivariate analysis for factors associated with OS is shown in Table 2. After ruxolitinib discontinuation, 25 patients received subsequent treatment at our center: SCT in 6, another JAK inhibitor in 11, other investigational agents in 3, chemotherapy in 5 patients. Median OS from ruxolitinib discontinuation was 20 months (95% CI: 12-28). Conclusion: Our data with the longest follow-up of patients receiving ruxolitinib for ≥3 years confirm the long-term benefit of this therapy with a median OS approaching 8 years since ruxolitinib treatment initiation.

Background. The TT approach has significantly improved the outcome of multiple myeloma (MM) by combining new drugs with a regimen that comprises induction, tandem autologous stem cell transplantation (ASCT), consolidation and maintenance. However, a group of 15% of patients with high risk multiple myeloma (HRMM) have derived little benefit despite similar response rates to induction chemotherapy and ASCT when compared to low risk MM. The poor outcome of HRMM is explained by early relapse post ASCT resulting in a short progression free survival (PFS) with only 15-20% of patients surviving long-term. Daratumumab (Dara) is a human IgG1k anti-CD38 monoclonal antibody that has shown favorable results in early single-arm studies and more recently in phase III studies for relapsed/refractory and newly diagnosed MM. In TT7, we introduced Dara during all phases of therapy, including immune consolidation early post ASCT, to improve responses rate and PFS in HRMM. Methods. Patients had newly diagnosed HRMM as defined by high risk cytogenetic abnormalities, presence of extramedullary disease, >3 focal lesions on CT-PET, elevated LDH due to MM, or ISS II/III with cytogenetic abnormality. Dara (16mg/kgx1) was added to induction with KTD-PACE (carfilzomib, thalidomide, dexamethasone; and four-day continuous infusions of cisplatin, doxorubicin, cyclophosphamide, etoposide). Conditioning for tandem autologous stem cell transplantation (ASCT) was with fractionated melphalan (50mg/m2x4) (fMEL) based on prior observations that patients with adverse cytogenetics fare better with fMEL rather than single high dose MEL200mg/m2.In the inter tandem ASCT period immunological consolidation with Dara (16mg/kg) alone for 2 doses was followed by Dara (16mg/kg) on day 1 combined with K (36mg/m2) and D (20mg) weekly for 2 cycles. DaraKD was administered to avoid treatment free periods allowing for myeloma regrowth. The 2nd ASCT was followed by further immunological consolidation with Dara (16mg/k) for 2 doses, and maintenance therapy for 3 yrs with 3-months block of alternating Dara-KD (dara 16mg/kg day 1; K 36mg/m2 and dex 20mg weekly) and Dara-lenalidomide (R)D (dara 16mg/kg day 1; R 15mg day 1-21 q28 and D 20mg weekly). Results. TT7 enrolled 43 patients thus far. The median follow-up was 11 months (range: 1-22). The median age was 61 yrs (range 44-73). Sixteen patients were ≥65 yrs (37.2%). A mean of 29.4x106 CD34+ cells/kg (range: 4.6-86.4) were collected. 36 patients completed ASCT #1 (83.7%) and 18 (41.9%) ASCT #2, whilst 14 patients have proceeded to the maintenance phase. R-ISS II/III or metaphase cytogenetic abnormalities were present in 85.1 and 58.1% of patients, respectively. Elevated LDH or >3FL on CT-PET were noted in 30 and 41.8%. The 1-yr cumulative incidence estimates for reaching VGPR and PR were 87 and 83%, respectively. A CR or sCR was achieved in 68 and 46%. The 1-yr estimates of PFS and OS were 91.6 and 87.2%. 40 subjects are alive, whilst 5 progressed on study therapy and 3 subsequently died. 38 patients are progression free at the time of reporting. Dara was well-tolerated and no subjects discontinued therapy due to dara-related side effects. The CR and sCR rates compared favorably to the predecessor HRMM TT5 protocol where CR and sCR rates were 59 and 27%. Conclusion. The early results of TT7 point to increased response rates of HRMM to a dara-based TT regimen with especially higher rates of CR and sCR. Longer follow-up is required to determine if these early results translate into superior PFS and OS.

Abstract Introduction : Cytogenetic abnormalities by fluorescence in situ hybridization (FISH) are clinically relevant prognostic factors in MM. Data in transplant ineligible patients treated with bortezomib or lenalidomide in first-line therapy for high-risk (HiR) patients is limited. Careful analysis of cytogenetic subgroups in trials comparing different treatments remains an important goal. This sub-analysis evaluates the impact of cytogenetics on outcomes in transplant-ineligible patients with newly diagnosed MM (NDMM) treated with bortezomib-based induction (BORT) or lenalidomide-based (LEN) treatment. Methods : In the GIMEMA-MM-03-05-trial, patients were randomized to bortezomib-melphalan-prednisone-thalidomide for 9 cycles followed by maintenance with bortezomib-thalidomide (VMPT-VT) vs VMP for 9 cycles, without maintenance. In the EMN01-trial, patients were randomized to melphalan-prednisone-lenalidomide (MPR) or cyclophosphamide-prednisone-lenalidomide (CPR) or lenalidomide plus low-dose dexamethasone (Rd) for 9 cycles, followed by maintenance with lenalidomide alone or plus prednisone continuously. Results of these studies have previously been reported (Palumbo A et al JCO 2010 and 2014; Magarotto V et al Blood 2016 127(9)). Cytogenetics were assessed using FISH. Patients were categorized into cytogenetic risk groups according to International Myeloma Working Group criteria. HiR cytogenetics included del(17p), t(4;14), and t(14;16); all other patients were categorized as standard risk (StR). Subgroup analyses were performed to determine the consistency of treatment effects of BOR vs LEN in the different subgroups using interaction terms between treatment and FISH, ISS, age, sex, Karnofsky PS and LDH. The different effect of BORT vs LEN in cytogenetic subgroups was confirmed by one sensitivity analysis where the follow-up of the BORT study was reduced to make the follow-up times similar; and by another sensitivity analysis with multiple imputation method for missing cytogenetic value. Results : 902 of 1165 patients from the intent-to-treat population had available cytogenetic profiles, with 243 (27%) patients in the HiR group and 659 (73%) in the StR group. In the BORT vs LEN groups, median age was 71 vs 73 years (p<0.001), ISS3 20% vs 27% (P=0.65), HiR patients were 29% vs 26%, StR patients were 71% vs 74% (p=0.32) and the median follow-up was 72.3 and 63.6 months, respectively. In the subgroup analysis, a significant difference was found in the cytogenetic subgroup with a superior advantage of BORT versus LEN in HiR group, whereas no significant difference was found between BORT and LEN in the other subgroups analyzed (ISS, age, sex, Karnofsky PS and LDH) (interaction-p=0.01) (Fig. 1 B). BORT treatment resulted in a reduced risk of death or progression compared with LEN in patients with HiR. In HiR patients, median PFS was 30.8 with BORT compared with 14.8 months with LEN (HR: 0.54; 95% CI: 0.41-0.72); in StR, median PFS was 29.1 with BORT compared with 22.1 months with LEN (HR: 0.87; 95%; CI: 0.72-1.05) (Fig. 1 A). Considering the standard of care VMP and Rd, in the HiR group (n=95) VMP resulted in a 48% reduced risk of death or progression compared with Rd (HR: 0.53; 95% CI: 0.34-0.83), whereas no significant difference in PFS was found in the StR group (n=273) (HR: 1.00; 95% CI: 0.75-1.33), interaction-p=0.02. BORT treatment resulted in a reduced risk of death in patients with HiR cytogenetics: median OS was 62.4 months with BORT compared with 43.2 months with LEN (HR: 0.68; 95% CI: 0.47-0.96); in StR, median OS was 78.1 months with BORT and was not reached with LEN (HR: 1.06; 95% CI: 0.82-1.36), interaction-p=0.04 (Fig. 1 A). In patients with del(17p) (n=131) median PFS was 18.0 vs 12.9 months for BORT vs LEN (HR: 0.71; 95% CI: 0.49-1.04), interaction-p=0.73. In patients with t(4;14) (n=118) median PFS was 31.5 vs 15.2 months for BORT vs LEN (HR: 0.41; 95% CI: 0.27-0.62) interaction-p=0.002. In patients with t(14;16) (n=31) median PFS was 36.2 vs 9.8 months for BORT vs LEN treated patients (HR: 0.34; 95% CI: 0.16-0.76), interaction-p=0.045. Conclusions : BORT treatment resulted in a PFS and OS benefit vs LEN in patients with HiR cytogenetics. Treatment with VMP led to a significant reduction of the risk of death or progression vs Rd in HiR patients. These results support VMP induction as a standard treatment option for patients with NDMM who are ineligible for transplant with HiR cytogenetics.
