Introduction: MCL is an aggressive type of non-Hodgkin's lymphoma, and was reported associated with early relapse and poor long-term survival. Treatment options include chemotherapy, immunotherapy, and molecular targeted therapies. As of 2019, molecular targeted therapies available in the United States indicated for the treatment of MCL include the proteasome inhibitor bortezomib, the immunomodulatory drug lenalidomide (following two previous lines of therapy), and the Burton's tyrosine kinase inhibitors (BTKIs) ibrutinib and acalabrutinib (following at least one previous line of therapy). Objective/Methods: To examine the real-world treatment patterns of patients with MCL globally, a systematic literature review was performed (2010-2019) with predefined methodology and inclusion and exclusion criteria. Embase and Medline were searched via ProQuest and the Cochrane Controlled Register of Trials (CENTRAL) via the Cochrane Library. Results: Of the 2207 publications identified, 6 publications (US, n = 4; EU, n = 2) provided information on the first-line treatment of MCL (Table). The most commonly administered first-line treatments were bendamustine-rituximab; high dose cytarabine ± rituximab; and cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and prednisone (CHOP) ± rituximab although differences were noted across studies. Most patients received rituximab first-line either in combination with chemotherapy (54.2%-87.5%) or as monotherapy (12.9%-28.9%); although in some studies, rituximab maintenance therapy could not be excluded. The most commonly administered second-line therapies were cytarabine, rituximab monotherapy, and ibrutinib while third-line therapies were rituximab monotherapy, ibrutinib, and temsirolimus. Nine studies provided data on the real-world treatment of MCL with the BTKI ibrutinib (EU, n = 3; US, n = 5; EU/US, n = 1; Table); no real-world studies were identified for acalabrutinib. Six studies enrolled patients only with relapsed or remitting MCL; 3 studies enrolled patients (≤7.5%) who received ibrutinib as first-line therapy. Ibrutinib second-line therapy was administered to 13%-20% of patients and third-line therapy to 21% of patients. Ibrutinib discontinuation rates in 7 studies varied from 38.7%-83.6%. Non-response, including relapse or progression (34.6%-100%), was the main cause of discontinuation, followed by toxicity/adverse events (8.1%-25.6%). Across studies, toxicity/adverse events causing ibrutinib discontinuation included atrial fibrillation, bleeding/hemorrhage, chronic obstructive pulmonary disease, diarrhea, herpes zoster, infection, leukocytosis/ lymphocytosis, lung cancer, myelodysplastic syndrome, and thrombocytopenia. Two studies provided information on ibrutinib dose reductions (16.4% of patients) and ibrutinib dose interruptions (7.8%-30.2% of patients). Treatment options administered post-ibrutinib included rituximab (52.7%), hyper-CVAD + rituximab (16.7%-25.8%), lenalidomide-based regimens (9.7%-41.5%), and bortezomib-based regimens (8.4%-34.4%). Conclusion: Our analyses showed that most patients with MCL received first-line chemoimmunotherapy, although regimens varied across studies. Approximately 13%-21% of patients received ibrutinib following first-line therapy. Most ibrutinib discontinuation was due to progression followed by toxicity/adverse events. Upon discontinuation of ibrutinib, considerable variation in treatments was seen and no standard therapy identified. Given the limitations of current therapies, there is a need for additional second- and third-line treatments for patients with MCL. Quantitative assessments of clinical endpoints from real-world studies evaluating BTKI therapies are also warranted. Disclosures Yang: BeiGene, Ltd.: Employment. Lesher:Pharmerit: Employment.

Aim: To conduct a retrospective analysis of electronic medical record data to understand real-world treatment patterns and overall survival (OS) in patients with metastatic non-small-cell lung cancer (NSCLC). Materials & methods: We included n = 9656 adults (≥18 years) with metastatic NSCLC and no prior therapy. Data from 1 January 2013 to 31 January 2017 were analyzed. Results: Carboplatin plus paclitaxel was the most common first-line therapy (18.6%), and nivolumab was the most common second- (31.0%) and third-line (38.4%) therapy; 26.7% of all patients were untreated. Median OS from initial metastatic diagnosis was 11.1 months (95% CI: 10.8–11.5). Second-line immunotherapy extended OS by over 3 months versus second-line chemotherapy. Conclusion: Platinum-based therapy was the most common first-line therapy, and immunotherapy was the most common second- and third-line therapy. Median OS of patients with metastatic NSCLC was <1 year.

Abstract Background and Objective : Hairy cell leukemia (HCL) is a rare condition and accounts for ~2% of all leukemia cases in the US. NCCN guidelines recommend first-line agents including pentostatin and cladribine among patients with HCL. However, a paucity of data exists with regard to real-world treatment patterns among patients with HCL. Current study evaluates treatment patterns and associated clinical outcomes among patients with HCL using a large US administrative claims database. Methods : This retrospective observational study was conducted using the IMS Health PharMetrics Plus Health Plan Claims Database (2006-2014), which includes over 150 million unique health plan members across the US and is nationally representative of the commercially-insured US population. Data includes date stamped medical and pharmacy records along with information on health plan enrollment. Individuals with at least 2 medical claims with a diagnosis for HCL (identified using ICD-9-CM cod: 202.4x) were selected and the first observed claim defined the "index date." Patients <18 years of age at index date or with other malignancies during 6 months (the "pre-index period") prior to index date were excluded. Patients were required at least 90 days of continuous enrollment (the variable "follow-up period") in the health plan post index date with exception of patients who died within 3 months of diagnosis. Patients were followed until death (recorded on inpatient discharge disposition), end of enrollment or end of database, whichever occurred earlier. Study measures including patient demographic and baseline clinical characteristics, line of therapy (LOT), treatment patterns, relapse (receipt of same or new regimen in subsequent LOT following a gap of 365 days) and refractory disease (receipt of same or new regimen where the gap of two adjacent LOTs was <365 days) and post-treatment complications were assessed during the follow-up period. All analyses were descriptive in nature. Results : The study cohort included 749 patients after applying the selection criteria (mean follow-up from diagnosis 32 months). At diagnosis, the mean age (standard deviation) of the study cohort was 56 (10) years and majority of patients were male (77%). Mean baseline comorbidity burden (assessed using Charlson Comorbidity Index score) was 0.8 (1.1) with hypertension (24%) and aplastic anemia (22%) being the two most common co-morbidities. Only 38% (n=282) of patients received first-line chemotherapy post diagnosis. Majority initiated first-line cladribine (76%) as a single agent, while 9% had evidence of single agent pentostatin. Mean time to initiation of first-line therapy from diagnosis was 132 (294) days and average time on first-line therapy was 34 (104) days. Among patients with first-line therapy 14% received second-line therapy and rituximab (53%) and cladribine (21%) were frequently observed second-line agents. Post first-line therapy, mean time to initiation of second-line therapy was 303 (406) days. Among second-line initiators, 76% had refractory disease and 24% had relapsed following first-line. Neutropenia and fever were frequently reported complications while on chemotherapy. Conclusion : The real-world chemotherapy utilization patterns observed in this study are consistent with the NCCN guidelines with cladribine and pentostatin being the agents of choice for first-line therapy. Following diagnosis, more than one-third of patients initiated chemotherapy and only a small proportion of these received second-line chemotherapy suggesting durable response with first-line therapy. Limited follow-up post first-line therapy may have impacted the proportion of patients initiating second-line therapy as well as categorization of refractory and relapse disease.

113 Background: Although the clinical trial WJOG7112G was failed to prove weekly paclitaxel with trastuzumab in patients with HER2-positive gastric or gastro-esophageal junction (GEJ) cancer refractory to trastuzumab is better than paclitaxel alone, there are limited data concerning efficacy of continuing trastuzumab beyond first-line progression in the real world. Methods: This retrospective study included all consecutive patients with HER2-positive advanced gastric or GEJ adenocarcinoma who received a chemotherapy with trastuzumab in first-line, or second-line, or third-line therapy between 2010 and 2016 in Chinese People’s Liberation Army General Hospital. Progression-free survival (PFS) and overall survival (OS) were estimated from the initial chemotherapy. Results: A total of 67 patients (median age, 59 years; male, 71.6%) with HER-2 positive advanced gastric or GEJ adenocarcinoma treated with chemotherapy plus trastuzumab initially in first (n = 50), second (n = 13), or third (n = 4) line of therapy were included. The median OS of trastuzumab for initial first-line, second-line, or third-line treatment was 16.7 months, 14.2 months, and 13.2 months, respectively (P = 0.83). In patients initially using trastuzumab in first-line therapy, the continuation (n = 19) versus discontinuation (n = 31) of trastuzumab beyond first-line progression was significantly associated with an improvement of median PFS (3.4 versus 1.9 months; P = 0.02), but not OS (19.0 versus 16.4 months; P = 0.13). In the multivariate analysis including the ECOG PS, number of metastatic sites and chemotherapy regimen, the continuation of trastuzumab beyond progression remained significantly associated with longer PFS (HR, 0.77; 95% CI, 0.41-0.93; P = 0.04), but not OS (HR, 0.85; 95% CI, 0.56-1.22; P = 0.24). Conclusions: This study suggests that HER-2 positive advanced gastric or GEJ adenocarcinoma patients could benefit from trastuzumab no matter when they start receiving trastuzumab. The continuation of trastuzumab beyond progression has clinical benefit in patients with HER2-positive advanced gastric cancer for PFS, but not for OS. Large scale prospective randomized validation is warranted.

e21104 Background: Crizotinib, alectinib, ceritinib, and brigatinib are approved as second line treatment for ALK+ NSCLC. Crizotinib was the first ALK inhibitor for first line therapy approved by Food and Drug Administration (2011) then ceritinib (2014), alectinib (2015), and brigatinib (2017) were approved as second line drugs. Following more data, these agents were approved as the first line therapy (2017 for ceritinib and alectinib; 2020 for brigatinib). These remain as a treatment option in patients who fail the first line therapy. Cost-effectiveness/utility analyses were conducted to assess clinical efficacy with varying costs of the agents. Methods: A three state Markov model were assumed (progression free, progression and death). Progression free survival (PFS) curves were digitized and fitted with exponential function. US payer perspective, a lifetime horizon, and discount rate of 3% were applied. Drug costs were Redbook wholesale acquisition cost. Other costs included were monitoring, adverse events and disease progression from published data (US$ 2020). Adverse events reported >5% in patients were included. Measured outcomes were PFS life years (PFSLY) and quality adjusted life years (PFSQALY). Crizotinib was the reference drug. Incremental cost-effectiveness and utility ratios (ICER/ICUR) of PFSLY and PFSQALY gained (PFSLYG, PFSQALYG) and lost were estimated. Base case (BCA) and probabilistic sensitivity analyses (PSA) were conducted. Results: Crizotinib was the reference drug for the following outcomes. For alectinib, with the decremental cost of -$14,653 (-$14,712), the incremental PFSLY of 0.16 (0.16) and PFSQALY of 0.05 (0.05) resulted in an ICER / PFSLYG of -$89,337 (-$88,604) and an ICUR / PFSQALYG of -$269,835 (-$266,510). For brigatinib, with the decremental cost of -$14,975 (-$14,954), the incremental PFSLY of 0.01 (0.01) and PFSQALY of ̃0.01 (0.02) yielded an ICER / PFSLYG of -$1,982,962 (-$1,431,631) and an ICUR / PFSQALYG of -$2,140,534 (-$570,538). For ceritinib, with the incremental cost of $7,590 ($7,514), there were decremental PFSLY of -0.01 (-0.01) and PFSQALY of -0.03 (-0.03). Conclusions: As second line treatment, crizotinib, ceritinib, and brigatinib had comparable PFSLYs and PFSQALYs while alectinib had the most PFSLY and PFSQALY and the lowest cost. Therefore, alectinib is the most cost-effective treatment for treating ALK+ NSCLC as the second line therapy.[Table: see text]

Abstract Abstract 4736 Background: Tyrosine Kinase Inhibitors (TKI) are the first line therapies for patients with chronic myelogenous leukemia (CML). The value of survival gains to patients associated with TKI treatment—in aggregate or relative to the cost of treatment—is unknown. Methods: Multivariate Cox proportional hazard models are used to construct real-world, community-based estimates of survival improvements in CML associated with the introduction of first-line TKI therapy, controlling for characteristics of patients which may independently affect survival. We then employ an economic framework following Becker, Philipson and Soares (2005) to calculate social value of infra-marginal improvements in survival gains due to treatment with TKIs. Finally, the value of community-based improvements in CML survival from treatment by newer TKIs used in second line is estimated by combining community-based survival data for first-line TKIs, along with clinical data on health improvements for CML patients receiving a TKI in second line. Results: Introduction of first-line TKIs in 2001 is associated with a real-world decrease in the all-cause mortality hazard rate of 0.183 (p < 0.01) for CML patients. A decrease of this magnitude is associated with an increase in life expectancy from 60 to 110 months for treated CML patients with median survival length in 2001. We estimate that patients place an annual value of $110,000 on first-line treatment with TKIs. This implies that for all patients in present and future CML cohorts, the present social value of first-line TKI therapy is $88bn. The present value of costs is estimated to be $8bn, suggesting that more than 90% of social value of TKIs in first line therapy is retained by patients. In second-line CML therapy, use of newer TKI agents is estimated to have created $47bn in social value, of which roughly 88% is retained by patients. This estimated value of the newer TKIs does not incorporate possible benefits in first-line therapy. Conclusions: In total, the TKI class in first and second-line theray has created over $135bn in social value. Approximately 90% of this value is retained by patients; approximately 10% is recouped by manufacturers. These estimates suggest that at current price levels, the vast majority of value created by new therapies in CML is appropriated by patients. In addition, since our estimates of survival community-based improvements are somewhat smaller than those contained in clinical trial estimates, this suggests the potential value of addressing real-world obstacles to efficacy, such as poor adherence.

387 Background: NET comprise a broad set of rare tumors. Almost 2/3 arise in the gastrointestinal (GI) tract. NCCN guidelines for unresectable GI NET recommend somatostatin analogues (SSA) first, however, guidelines do not recommend a particular sequence for remaining therapies. Our objective is to describe real world treatment patterns of GI NET. Methods: This retrospective study combined 2 claims databases to examine newly pharmacologically treated patients using tabular and graphical techniques. Treatments included SSA, cytotoxic chemotherapy (CC), targeted therapy (TT), interferon (IF) and combinations. Patients ≥ 18 years, with ≥ 1 inpatient or ≥ 2 outpatient claims for GI NET who received pharmacologic treatment from 7/1/09-6/30/14 were identified. A 6 month clean period prior to first treatment ensured patients were newly treated. Patients were followed until end of enrollment. Results: We identified 2,258 newly treated GI NET patients. 59.6% started first line therapy with SSA monotherapy, 33.3% CC, 3.6% TT, and 0.5% IF. The remainder received combination therapies. Mean follow up was 576 days. Mean duration of first line therapy was 361 days for all newly treated patients (449 SSA, 215 CC, 267 TT). 58.9% of patients had no subsequent pharmarcological treatment after discontinuation of first line therapy.The most common second line was combination therapy with SSA (i.e., CC or TT added). In patients who did not begin with SSA, most received SSA as second line. In graphical pattern analysis, there was no clear pattern visible after first line therapy. Conclusions: More than 1/2 of pharmacologically treated patients began treatment with SSA and 1/3 with CC, with duration of use > 1 year and just over 6 months, respectively. We found treatment patterns after first line were unclear, and more than 1/2 of patients had no subsequent pharmacological treatments after discontinuing first line therapy. It is unclear whether there is underutilization of the pharmacological therapy or this is due to stable disease status after alternative non-pharmacological treatment. Future studies directed at understanding treatment patterns using patient medical records are warranted. As new treatments emerge, reassessment of treatment patterns may be needed.

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 Background Eosinophilic gastrointestinal disorders, also known as eosinophilic gastroenteritis, are rare inflammatory conditions characterized by eosinophilic infiltration of different parts of the gastrointestinal tract, along with peripheral eosinophilia in most cases. Other known causes for gut eosinophilic infiltration must be excluded to confirm the diagnosis of eosinophilic gastroenteritis. Symptoms of the disorder depend on the affected gastrointestinal tract segment and depth of involvement. Treatment includes systemic glucocorticoids and/or dietary therapy with an empiric elimination diet. Second line therapies include the leukotriene receptor antagonist montelukast, and other anti-allergy drugs such as mast cell stabilizers (including cromolyn and the H1-antihistamine ketotifen), suplatast tosilate which is a selective Th-2 cytokines (IL-4 and IL-5) inhibitor, and the monoclonal anti-IgE antibody omalizumab. We report a case of eosinophilic gastroenteritis who was successfully treated and achieved remission with montelukast as an initial monotherapy. Upon extensive literature review, this represents the second reported adult case of eosinophilic gastroenteritis who responds to montelukast alone as a first line therapy. Case presentation A 49-year-old female presented with recurrent abdominal pain, vomiting, diarrhea and unexplained eosinophilia. She was diagnosed with eosinophilic gastroenteritis and was successfully treated with montelukast monotherapy. After 7 days of therapy, the patient responded well and had complete resolution of her gastrointestinal symptoms and peripheral eosinophilia. Patient remained in remission on follow-up after 12 months. We reviewed the literature for leukotriene antagonist use in the treatment of eosinophilic gastroenteritis and included the cases treated with the leukotriene antagonist montelukast as an initial therapy or as a second line therapy for refractory disease. Conclusion Montelukast may be an effective treatment for eosinophilic gastroenteritis, either alone or in combination with systemic steroids or ketotifen. Our patient is the second reported adult case of eosinophilic gastroenteritis who responded to montelukast alone as a first line therapy. Further studies and clinical trials are required to confirm efficacy compared to standard therapy.

The treatment pattern of cutaneous T-cell lymphoma (CTCL) remains diverse and patient-tailored. The objective of this study was to describe the treatment patterns and outcomes in CTCL patients who were refractory or had relapsed (R/R) after a systemic therapy. A retrospective chart review study was conducted at 27 sites in France, Germany, Italy, Spain and the United Kingdom (UK) of patients who received a first course of systemic therapy and relapsed or were refractory. Data were collected longitudinally from diagnosis to first-, second- and third-line therapy. The study included 157 patients, with a median follow-up of 3.2 years. In total, 151 proceeded to second-line and 90 to third-line therapy. In the first line (n = 147), patients were treated with diverse therapies, including single- and multi-agent chemotherapy in 67 (46%), retinoids in 39 (27%), interferon in 31 (21%), ECP in 4 (3%), corticosteroids in 3 (2%) and new biological agents in 3 (2%). In the second line, the use of chemotherapy and retinoids remained similar to the first line, while the use of new biologics increased slightly. In sharp contrast to the first line, combination chemotherapy was extremely diverse. In the third line, the use of chemotherapy remained high and diverse as in the second line. From the time of first R/R, the median PFS was 1.2 years and the median OS was 11.5 years. The presented real-world data on the current treatments used in the management of R/R CTCL in Europe demonstrate the significant heterogeneity of systemic therapies and combination therapies, as expected from the European guidelines.
