Background In the last decades the introduction of novel drugs has greatly improved the prognosis of multiple myeloma (MM) patients. We have investigated healthcare resource utilization and sickness absence-associated productivity loss over time in a population-wide, retrospective registry study in Sweden. Methods 8,693 patients were identified in the National Cancer Register with a MM diagnosis from July 2001 to December 2015 and followed until 2016. Specialized healthcare usage (inpatient admissions and outpatient visits) were obtained from the Patient Register and costs were estimated by weighted DRG codes. For patients under 66 years of age, sickness absence and salary information were obtained by linkage to the LISA Register. Analyses were performed separately on patients who underwent autologous stem cell transplantation (ASCT) (n=1,425) and on non-transplanted patients (n=7,012) and stratified by diagnosis periods 2001-2005, 2006-2010 and 2011-2015 to reflect increased introduction of effective drugs into clinical care. Median age was 60 years in the ASCT group and 75 years in the non-ASCT group. Results The number of MM patients that underwent ASCT increased over time (n= 282 in 2001-2006 to n= 592 in 2011-2015). MM patients diagnosed most recently had improved overall survival (OS), with five-year OS rate increasing from 52% to 58% to 62% for patients diagnosed in 2001-2005, 2006-2010 and 2011-2015, respectively (p<0.0001). Patients diagnosed during 2011-2015 spent on average 20% and 9% less total time in specialized healthcare than patients diagnosed during 2001-2005 and 2006-2010, respectively (adjusting for sex, age at ASCT, weighted comorbidity score at ASCT and per follow-up year and education at ASCT). This decrease was driven by less usage and time in both inpatient and outpatient care. Adjusted sickness absence time decreased by 41% and 38% in the third follow-up year for patients diagnosed during 2011-2015 compared to patients diagnosed during 2001-2005 and 2006-2010, respectively. Productivity loss costs represented about 45% of total costs (healthcare resource costs ~55%) in the first two follow-up years, but decreased over time. The cumulative median per person cost (healthcare- and productivity-related) over the three follow-up years post-diagnosis decreased by 21% in 2011-2015 (€52,273) compared to 2001-2005 (€66,182), despite an 8% increase in three-year OS over the same period. The number of non-ASCT MM patients also increased over time (n=2,053 in 2001-2005 to n= 2,587 in 2011-2015). Median survival increased from 2.5 years to 3.4 years for patients diagnosed during 2001-2005 compared to 2011-2015. Average total time spent in specialized healthcare was reduced by 29% and 12% for patients diagnosed during 2011-2015, compared to patients diagnosed during 2001-2005 and 2006-2010, respectively (adjusting for sex, age at diagnosis, weighted CCS at diagnosis, weighted CCS per follow-up year and education at diagnosis). This was associated with decreased need for inpatient care and a shift towards more outpatient usage. By the third follow-up year, the adjusted sickness absence time in patients diagnosed during 2011-2015 was reduced by 44% and 23% compared to patients diagnosed in 2001-2005 and 2006-2010, respectively. Productivity loss accounted for approximately 15% of total costs (healthcare resource costs ~85%) and was stable over follow-up years. The cumulative median per-person cost (healthcare- and productivity-related) over three follow-up years was similar for patients diagnosed in 2001-2005 (€25,621) and 2011-2015 (€26,592), despite a 12% increase in three-year OS over the same period. Conclusion The availability of new treatment options for MM patients in Sweden over time was associated with less healthcare usage, less time spent in healthcare and lower productivity loss due to sickness absence for both ASCT and non-ASCT-treated patients. These improved clinical and economic outcomes provide policy makers, healthcare providers and physicians with invaluable real-world insights for cost-benefit considerations in the continued development and introduction of effective treatments for MM.

Abstract Introduction: Multiple myeloma (MM) is an incurable hematologic condition that is associated with high Tx costs. Resource consumption is driven by hospitalization and medical utilization, which is highest during periods of uncontrolled disease, such as after diagnosis and during relapses (De Portu 2013). In the pivotal phase 3 FIRST trial, continuous Tx with lenalidomide plus low-dose dexamethasone (Rd) was compared with fixed-duration Rd (Rd18) or fixed-duration combination Tx with melphalan, prednisone, and thalidomide (MPT), each for 18 months (mos), in NDMM pts who were ineligible for stem cell transplantation. Continuous Rd extended progression-free survival (PFS) and overall survival (interim analysis) vs. MPT. However, it is still unclear whether extending Tx duration with Rd adversely affects healthcare resource utilization. This analysis quantifies the rates of hospitalizations and medical utilization with continuous Rd over time based on data collected in the FIRST trial. Methods: The FIRST trial (N = 1,623) was a pivotal multinational, randomized, open-label study with a median follow up of 37 mos. Non-protocol-driven resource-use data was collected until subjects discontinued study Tx. To assess whether continuous Rd increases healthcare resource utilization over time, the rates of resource utilization for subjects treated with continuous Rd (N = 535) were plotted for up to 48 mos. In addition, hospitalization and medical utilization rates during the Tx period (18 mos) were estimated and compared between the 2 fixed-duration Tx arms. Results: Resource utilization amongst pts treated with continuous Rd declined over time (Figure). The annualized hospitalization rate in the first 3 mos was 3.2 times higher than the average rate for the remaining 45 mos of follow-up (2.02 vs. 0.62), and 4.2 times higher for medical utilization (5.66 vs. 1.34). After 4 years (yrs) of continuous Rd Tx, hospitalization and medical utilization rates were estimated to be 83% and 84% lower than those observed in the first 3 mos of Tx, reflecting the long-term disease control observed with continuous Rd in the FIRST trial. The highest hospitalization rates were associated with infections (0.20 per patient year), cardiovascular disorders (0.06), and respiratory and thoracic disorders (0.05). The mean (standard deviation) length of stay per admission was 14.08 (21.19) days. The highest medical utilization rates were associated with blood transfusions (0.76 interventions per patient year), general imaging procedures (0.21), respiratory and thoracic imaging procedures (0.20), and therapeutic interventions (0.09).The hospitalization rates for the fixed dose Tx arms were 0.91 (Rd18) and 0.79 (MPT) per patient year of follow-up during the Tx period of 18 mos, resulting in a rate ratio (RR) of 1.15 (1.01–1.30). The equivalent rates for medical utilization were 3.00 (Rd18) and 2.86 (MPT) medical interventions per patient year (RR = 1.05 [0.98–1.12]). Conclusions: The rates of resource utilization among pts treated with continuous Rd dropped substantially after the first 3 mos of Tx, and then gradually declined as Tx duration increased. The findings suggest that continuous Tx with Rd does not further increase resource utilization in hospitalizations and medical utilization compared to fixed-duration Tx. A comparison between the 2 fixed arms showed a 15% increase in hospitalization with Rd18 vs. MPT, and no differences in medical utilization between the 2 arms. A limitation of this analysis is that the resources were collected only while pts were receiving their respective Txs. Future analysis should include all costs generated by healthcare resources throughout pts Tx, including Tx-free intervals, and the costs associated with relapses.

Abstract Background: Follicular lymphoma (FL) is indolent and typically incurable, and patients (pts) often receive multiple lines of therapy (LOTs) throughout their lifetime (Batlevi et al. Blood Cancer J 2020). Options at relapse following first- or second-line anti-CD20 monoclonal antibody (MoAb)-containing regimens remain limited, although approved third- and later-line therapies (3L+) have become available. Few studies have estimated the real-world economic burden of pts with relapsed/refractory (R/R) FL requiring 3L+ treatment. The aim of this study was to examine real-world healthcare resource utilization (HRU) and costs among pts receiving FL therapies in the 3L+ setting. Methods: This retrospective cohort study used administrative claims data from the IQVIA PharMetrics ® Plus, a US commercial claims database. Adult pts who had ≥1 inpatient claim or ≥2 outpatient claims with an FL diagnosis from January 1, 2011 to September 30, 2020 were included. The final 3L+ population was identified by combining two groups: (1) pts newly initiating FL treatment (defined as systemic anti-cancer therapies listed in the National Comprehensive Cancer Network [NCCN] guidelines) between January 1, 2012 and September 30, 2017 and receiving any subsequent 3L FL treatment during the study period; and (2) pts who received a NCCN-recommended 3L+ FL phosphatidylinositol-3-kinase inhibitor (PI3Ki) between January 1, 2012 and March 30, 2020. Group 1 captured pts who received 3L FL therapies by a proxy algorithm for LOT (Optum 2018) based on NCCN guideline-listed therapies, and group 2 captured pts who received newer available PI3Kis, which are only approved in pts who have received ≥2 previous systemic FL therapies. The index date was the 3L treatment initiation date or the initial PI3Ki claim date. All pts had ≥12 months of pre- and ≥6 months of post-index continuous enrollment in medical and pharmacy benefits. Pts with other primary cancers or evidence of histological transformation during the pre-index period, or clinical trial participation during the study period were excluded. All-cause HRU and all-cause and FL-related (i.e. claim with a FL diagnosis in any position) costs (2020 USD) were annualized during the 3L+ treatment period (defined as the period from index 3L+ treatment until the end of the LOT) to mitigate the effects of different follow-up times. Results: Overall, 100 pts who initiated 3L+ FL treatment were included. Of these, 51% of pts were male, and the mean (standard deviation [SD]) age at index and Charlson Comorbidity Index (non-cancer) at baseline were 62 (10.1) years and 0.9 (1.5), respectively. Mean follow-up time was ~2.3 years, and the mean duration of index 3L+ FL treatment was 273 days. Overall, 44 pts (44%) received subsequent treatment. The most common therapy classes received for index 3L+ FL treatment were oral PI3Kis (n=45, 45%), anti-CD20 MoAb monotherapy (n=19, 19%), and chemoimmunotherapy (CIT; n=18, 18%). A summary of all-cause annualized HRU in pts receiving index 3L+ FL treatment is provided by visit type (Table). For all 3L+-treated pts, mean (SD) all-cause annualized total healthcare costs in the 3L+ treatment period were $193,207 ($148,702), and 83% of total healthcare costs were FL-related costs ($159,815 [$138,477]; Figure). Of the most common 3L+ FL therapy classes, CIT had the highest FL-related mean annualized costs ($214,631 [$120,799]), followed by oral PI3Kis ($131,208 [$86,712]), and anti-CD20 MoAb monotherapy ($105,061 [$73,445]). Conclusions: The economic burden of pts with R/R FL requiring 3L+ FL treatment is substantial, with FL-related costs comprising the majority of total healthcare costs. More than 40% of the pts in this analysis needed subsequent treatment, further compounding the challenges faced by this high-risk population. This analysis provides an initial benchmark for ongoing and future evaluations of the economic value of currently available and emerging therapies for multiple relapsed FL, though future studies with larger sample sizes and longer follow-up are warranted.

Abstract Systemic mastocytosis (SM) is a rare mast cell neoplasm driven by KIT D816V mutation. Advanced SM (AdvSM) includes three disease subtypes: aggressive SM, SM with associated hematological neoplasm, and mast cell leukemia. 1 Advanced disease onset often develops in patients above the age of 60. 1 Patients with AdvSM experience a range of severe symptoms including organ damage and shortened survival. 2 There is limited research quantifying the impact of AdvSM on healthcare resource utilization (HCRU) and costs, particularly within the Medicare population. This retrospective study compared direct HCRU and costs in Medicare beneficiaries with AdvSM to a matched cohort of beneficiaries without SM. This study used Centers for Medicare and Medicaid Services-sourced 100% Medicare Fee for Service (FFS) claims (Parts A/B/D) to identify newly diagnosed SM patients with >2 medical claims for SM (ICD-10-CM Dx codes: D47.02 OR C94.30 OR C94.31 OR C94.32 OR C96.21) between 01/01/2017 and 12/31/2018. The index date was the date of first observed SM diagnosis code. A claims-based algorithm was used to determine AdvSM subtype. Patients were required to have continuous enrollment in Medicare Parts A/B/D for 12 months pre- and post-index. AdvSM patients were direct matched (1:1) to a non-SM control cohort on age, sex, race, index year, Medicare-Medicaid dual eligibility, and Charlson Comorbidity Index score. HCRU and costs were assessed pre- and post-index. Chi-square and t-tests were used to evaluate differences in outcomes between AdvSM and non-SM patients. Medical costs are reported in 2021 USD. After matching, there were 339 AdvSM and 339 non-SM patients. Mean [SD] age was 68.2 [13.2] among AdvSM and 68.5 [13.9] among non-SM patients. More than 25% of patients were <65 years old at index and qualified for Medicare due to a preexisting disability. Majority of patients were female (59%) and White (91%). Compared to non-SM patients, AdvSM patients had more specialist and emergency department (ED) visits during the baseline period. Baseline prevalence of asthma (26% vs. 16%, p=0.0009) and any malignancy (60% vs. 23%, p<0.0001) was higher among AdvSM patients compared to controls, and lower for hypertension (70% vs. 81%, p=0.0006), and diabetes with and without complications (28% vs. 52%; 16% vs. 33%; both p<0.0001). During the 12 months post-index, all cause total healthcare expenditures (Parts A/B/D) were significantly higher for AdvSM patients than for non-SM comparator patients (mean [SD]: $123,412 [$180,386] vs. $47,988 [$64,693]; p<0.0001). Pharmacy costs (Part D) were a key driver of the total, accounting for 41% ($50,494 [$140,561]) of the total costs for AdvSM patients and 19% ($9,221 [$22,270]) of the total for non-SM patients. Inpatient hospital stays made up 24% of AdvSM patient costs and 26% of non-SM patient costs. More AdvSM than non-SM patients had ≥1 inpatient hospitalization (58% vs. 42%; p=0.0001), and length of hospital stay was significantly longer for AdvSM patients (13.1 [26.95] days) than for comparator patients (5.22 [12.66]; p<0.0001). Mean [SD] number of ED visits per patient was over twice as high for AdvSM than for non-SM patients (3.7 [12.0] vs. 1.6 [3.6]; p=0.0026). AdvSM patients had more than 5 times as many oncology/hematology and allergy/immunology physician office visits per patient versus non-SM controls (10.9 [21.5] vs. 2.0 [7.2]; 2.3 [7.4] vs. 0.1 [0.7]; both p<0.0001). AdvSM patients were higher utilizers of epinephrine (29.2% vs. <3% non-SM patients; p<0.0001), oral and systemic corticosteroids (54.0% vs. 38.1%, p<0.0001; 51.9% vs. 41.6%, p=0.0071), chemotherapy (12.09% vs. 6.78%; p=0.0181), and omalizumab (4.7% vs. 0.0%, p<0.0001). AdvSM Medicare FFS patients were more resource intensive and had 2.5 times higher per-patient healthcare costs in the 12 months following SM diagnosis compared to a matched cohort of non-SM patients. These costs were driven by significantly higher rates of inpatient stays, more frequent ED and physician outpatient visits, and higher utilization of multiple medications. Notably, AdvSM patients in this analysis included a larger proportion of patients <65 years old with preexisting disability compared to the broader Medicare population (~25% vs. 14%), suggesting that AdvSM patients may be more likely to qualify for Medicare due to disability rather than age compared to the overall Medicare population. Further research in this area is warranted.

Abstract Systemic mastocytosis (SM) is a rare mast cell disease driven by the KIT D816V mutation in which mast cells accumulate in ≥1 tissues or organs resulting from clonal proliferation of abnormal mast cells in one or more extracutaneous organs. Most forms of SM are non-advanced (non-AdvSM). To date, the economic burden of non-AdvSM has not been well-studied among Medicare patients. This study compared direct healthcare resource utilization (HCRU) and healthcare costs in Medicare beneficiaries with non-AdvSM and a matched cohort without SM. This study used Centers for Medicare and Medicaid Services-sourced 100% Medicare Fee for Service (FFS) claims (Parts A/B/D) and identified newly diagnosed non-AdvSM patients who had ≥2 medical claims for SM (ICD-10-CM Dx codes: D47.02 OR C94.30 OR C94.31 OR C94.32 OR C96.21) between 1/1/2017 and 12/31/2018. Patients were classified as non-AdvSM using a claims-based algorithm. The index date was the date of first observed SM diagnosis. Continuous enrollment in Medicare Parts A/B/D for 12 months pre- and post-index was required. Non-AdvSM patients were direct matched (1:1) on age, sex, race, index year, Medicare-Medicaid dual eligibility, and Charlson Comorbidity Index score to a non-SM control cohort. HCRU and costs were assessed during the 12 months pre- and post-index. Medical costs are reported in 2021 US dollars. Post match, there were 333 non-AdvSM and 333 non-SM patients. Mean [SD] age of the non-AdvSM cohort was 67.3 [11.7] and 67.8 [13.3] years for the control cohort. Over 25% of patients were <65 years of age at index and originally qualified for Medicare with a disability. Most (76%) patients were female, and 94% were White. During the 12-month pre-index period, non-AdvSM patients had more specialist physician office visits per patient (mean [SD]: 15 [15]) compared to non-SM patients (10 [13]; p<0.01). Non-AdvSM patients vs. controls had higher prevalence of asthma (29% vs. 15%, p<0.0001) and any malignancy (43% vs. 15%, p<0.0001) and lower prevalence of hypertension (58% vs. 68%, p=0.0103), diabetes with and without complications (19% vs. 34%; 8% vs. 15%; both p<0.0001), and renal disease (7% vs. 11%, p=0.0439). Non-AdvSM patients were also higher utilizers of corticosteroids (64% vs. 54%, p=0.0094), epinephrine auto-injectors (31% vs. 1%, p<0.0001), and omalizumab (6% vs. 0%, p<0.0001) compared to non-SM patients. Total (Parts A/B/D) healthcare costs in the 12-month follow up period were almost one-third higher for non-AdvSM patients than for non-SM controls (mean [SD]: $40,250, [$54,563] vs. $30,013 [$51,235]; p=0.0128). Pharmacy (Part D only) expenditures were also significantly higher ($13,938[$38,367] vs. $5,745 [$17,213], p=0.0004) and accounted for a greater proportion (34.6% vs. 19.1%) of total costs for non-AdvSM patients vs. non-SM patients. Non-AdvSM patients were high utilizers of physician office visits post-index compared to non-SM controls; more non-AdvSM patients had ≥1 oncology/hematology visit (36.9% vs. 12.9%; p<0.0001), or allergy/immunology visit (47.2% vs. 3.9%; p<0.0001) and mean [SD] visits per patient were higher among non-AdvSM patients (3.4 [11.8] vs. 1.3 [6.4] oncology/hematology, p=0.0049; 3.3 [9.5] vs. 0.2 [1.7] allergy/immunology, p<0.0001). Approximately 40% of non-AdvSM patients filled ≥1 prescription for an epinephrine auto-injector compared with <3% in non-SM patients (p<0.0001). More non-AdvSM patients had prescriptions for H1 antihistamines (13.8% vs. 5.4%, p=0.0002), oral and systemic corticosteroids (39.0% vs. 27.9%, p<0.0001; 51.7% vs. 32.1%, p=0.0079, respectively), leukotriene antagonists (40.5% vs. 8.7%; p<0.0001), and omalizumab (6.9% vs. 0.0%, p<0.0001). Compared to a matched cohort of non-SM Medicare FFS patients, non-AdvSM Medicare patients had 30% higher mean per patient total healthcare expenditures ($40,250 vs. $30,013), driven by more prescription drug use and higher utilization of outpatient resources, specifically visits to oncologists/hematologists and allergists/immunologists. Notably, this analysis does not represent the HCRU and costs of the most severe SM patients. Further research to understand the basis of the higher proportion of non-AdvSM patient in this analysis who were <65 years and qualified for Medicare with a disability (vs. 14% in all of Medicare), and the corresponding long-term medical costs among these patients is warranted.

Abstract Background: Obinutuzumab (G) is an anti-CD20 monoclonal antibody approved in the US for the first-line (1L) treatment of follicular lymphoma (FL), relapsed or refractory FL, and 1L chronic lymphocytic leukemia. G plus chemotherapy (G-chemo) demonstrated superior progression-free survival versus (vs) rituximab (R) plus chemotherapy (R-chemo) in patients with previously untreated FL in the Phase III, randomized GALLIUM study (NCT01332968; Marcus et al. N Engl J Med 2017). R-bendamustine (R-benda) and G-bendamustine (G-benda) are among the most commonly used chemoimmunotherapy (CIT) regimens for FL (Ta et al. J Clin Oncol 2021), and information on comparative healthcare resource use (HRU) and real-world costs associated with G-chemo vs R-chemo in previously untreated FL patients is limited. The aim of this study was to compare HRU and costs for G-benda and R-benda for the 1L treatment of FL using US claims databases. Methods: This was a retrospective cohort study using administrative claims data from the IQVIA PharMetrics® Plus and IBM® MarketScan Commercial and Medicare Supplemental databases. We identified patients aged ≥18 years, who had ≥1 inpatient claim or ≥2 outpatient claims with a diagnosis of FL from February 1, 2015 to September 30, 2020, and received 1L R-benda or G-benda between February 1, 2016 and March 31, 2020. The first claim for FL treatment was the index date. All patients had ≥12 months of pre- and ≥6 months of post-index continuous enrollment in medical and pharmacy benefits. Patients with other primary cancers, FL treatment, diffuse large B-cell lymphoma (DLBCL), or stem cell transplant during the pre-index period, or clinical trial participation or end-stage renal disease during the study period were excluded. Patients initiating 1L G-benda were propensity score matched 1:2 with patients initiating 1L R-benda based on age, sex, Charlson Comorbidity Index (CCI), region, and insurance type. All-cause and FL-related (i.e. claim with a FL diagnosis in any position) HRU and costs (2020 USD) per patient per month (PPPM) during the follow-up period were reported. Patients were followed until the earliest of initiation of second-line therapy, end of continuous follow-up, or end of data availability. Results: Overall, 270 patients were included; of these, 90 (33.3%) patients receiving G-benda were matched to 180 (66.7%) patients receiving R-benda for 1L treatment of FL. 45.2% were male, and the mean (standard deviation [SD]) age and CCI at index date were 59.1 (9.9) years and 1.7 (1.1), respectively. Median follow-up was 7.4 months. After matching, baseline characteristics were well-balanced between R-benda and G-benda patients (standardized mean difference [SMD] <0.1). Both all-cause and FL-related HRU were similar between R-benda and G-benda treated patients across all service categories (Figure 1). Total all-cause mean [SD] PPPM costs were also similar in G-benda vs R-benda patients ($21,378 [$15,242] vs $21,352 [$14,145]; p=0.77) (Figure 2). The majority of the total costs were FL-related and comparable across both patient groups: $17,353 ($11,370) for G-benda vs $17,724 ($13,530) for R-benda (p=0.71). Specifically, FL-treatment related costs PPPM were $17,070 ($14,064) for G-benda; this is comparable to $16,138 ($11,828) PPPM for R-benda (p=0.39). Conclusions: Our study found similar total costs of care and HRU among patients receiving 1L G-benda versus those receiving R-benda, providing real-world economic evidence that complements clinical trial data supporting the use of G-chemo for 1L treatment of FL.

Introduction: Acute myeloid leukemia (AML) is a malignant form of bone marrow cancer commonly diagnosed in older adults. The age-adjusted incidence of AML in the USA is 4.3 per 100,000, with a median age of 68 years at diagnosis. Once diagnosed, treatment options include intensive chemotherapy to induce remission followed by post-remission therapies, including stem cell transplantation, repeated rounds of intensive chemotherapy to achieve durable disease control, or supportive care. Prognosis following relapse is poor with a median survival of 8-10 months. While previous studies have shown that much of this time following relapse is spent in an inpatient or outpatient setting, few studies have looked at the frequency and costs of this healthcare utilization. This study examined annual healthcare resource utilization and associated costs incurred in patients diagnosed with relapsed AML. Methods: A retrospective analysis was conducted in the Premier Healthcare Database, a nationally representative, all-payer hospital administrative database containing more than 1 billion inpatient and hospital-based outpatient encounters. Using International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes for AML in relapse, the study identified adult patients during the period from January 1, 2016 to March 31, 2019. The date of the first encounter with a relapse diagnosis served as the index date. Patients were followed from index date to inpatient death, one year post-relapse, or end of study period (September 30, 2019). Unadjusted descriptive analyses were performed to describe patient demographics, hospital characteristics, and comorbid conditions, as well as outcomes of interest, including outpatient treatment days, inpatient and intensive care unit (ICU) admissions, and associated costs. Results: A total of 2,290 patients were identified for inclusion in the study. Mean age was 61.2 years (median 65.0 years) and 46.9% were female. Healthcare coverage was Medicare (51.2%), commercial insurance (29.1%), Medicaid (13.8%), or other (5.9%). Mean Charlson Comorbidity Index was 4.02 (SD 2.66) and common comorbidities were diabetes (31.0%), congestive heart failure (19.5%), and chronic obstructive pulmonary disease (19.0%). Patients' length of follow-up varied: < 90 days (49.4%), ≥ 180 days (32.8%), and ≥ 360 days (16.8%). During the 1-year follow-up period, patients were seen in the outpatient hospital treatment setting for a median of 7.0 (IQR 2-19) days. In addition to outpatient treatment, patients incurred a total of 1,798 inpatient hospitalizations (median 2.0 per patient, IQR 1-3), with a median length of stay (LOS) of 10.0 (IQR 6-19) days. Among hospitalized patients, 554 (30.8%) included an ICU admission with a median LOS of 3.0 (IQR 1-5) days per admission. Median cost per day for outpatient treatment was $1,039 (IQR $487-2,305) and patients incurred a median cost of $6,569 (IQR $1,872-23,542) in this setting. For hospitalizations, median cost of an inpatient stay was $21,592 (IQR $9,852-45,000). Cost of an ICU admission during a hospital stay was $13,348 (IQR $6,115-28,266). Hospital treatment costs incurred by this cohort of patients in the year following relapse totaled $169 million, of which 82% ($139 million) was attributable to the inpatient setting. Conclusions: After a relapse of AML, patients are commonly admitted to the hospital, oftentimes to the ICU, and incur substantial costs associated with treatment. These results suggest that cost savings could be realized with therapies that would forestall relapse and improve survival in patients with AML.

Abstract Introduction: Although multiple myeloma (MM) is currently incurable, the survival rate has improved over the past decade. Despite advances in treatment, most patients will become refractory to treatment. Lenalidomide and proteasome inhibitors (PI) are frequently used in early MM treatment regimens; however, there is a need to further understand how follow-up treatments affect patient outcomes. The aim of this retrospective database analysis was to examine the demographics, clinical characteristics, treatment sequencing, and overall survival in US Medicare patients with MM who initiated any MM treatment after observed treatment with lenalidomide and a PI. Methods: Claims data from the Centers for Medicare and Medicaid Services (CMS) were assessed during the study period of January 1, 2016, through December 31, 2018. Medicare patients who were diagnosed with MM and had any MM therapy at least 28 days following treatment with lenalidomide and PI were eligible. The index date (ID) was the date of the first observed claim for any MM therapy as a next line of therapy (LOT) following treatment with lenalidomide and a PI. Patients were required to have ≥6 months of continuous enrollment prior to ID (baseline period). Patient data were assessed until health plan disenrollment, death, or end of study period (whichever occurred first). Results: This study identified a cohort of 6590 eligible Medicare patients with MM exposed to lenalidomide and a PI. The mean age (standard deviation) was 72 (8.0) years, and 53.0% of patients were male. The Southern United States showed the largest representation of patients in this population (37.0%). The top baseline comorbidities included osteoarthritis (83.0%), hypertension (76.9%), anemia (76.7%), and respiratory infections (75.7%). PIs used in the lenalidomide/PI combination in the baseline period included bortezomib (67%), carfilzomib (30%), and ixazomib (29%). A patient could have received one or more of these PIs. Of the 6590 patients who received index therapy, 51% had triplet therapy, 35% had doublet therapy, 10% had monotherapy, 3% had quad therapy, and <1% had another combination. Among the 78% patients with a post-index LOT, 37% had triplet therapy, 37% had doublet therapy, 22% had monotherapy, 4% had quad therapy, and <1% had another combination. The most common therapies during the follow-up were dexamethasone (88%), lenalidomide (73%), bortezomib (45%), pomalidomide (31%), and daratumumab (31%). Patients could have received one or more of these therapies in the follow-up period. Overall, 4,788 (73%) patients were retreated with lenalidomide and 5,613 (85%) patients were retreated with a PI during the follow-up period. Between the ID and the end of study period, 24.4% of patients died. The median (range) time to death was 211 (1─890) days from ID. Conclusions: This study showed there was wide variation in subsequent treatment strategies following lenalidomide/PI exposure. After exposure, patients were most often treated with triplet therapies, and there was frequent re-treatment with previously used agents and/or classes. These results highlight the need for novel treatments/classes of therapy and sequencing strategies that may improve outcomes in patients with MM.

BACKGROUND: ESMO guidelines (Moreau P, et al. Ann Oncol. 2017) recommend lenalidomide- (LEN) and bortezomib-based (BORT) regimens as first line (1L) treatment (tx) options for patients (pts) with multiple myeloma (MM) who are ineligible for stem cell transplantation (NSCT). The aim of this study was to determine tx outcomes and healthcare resource utilization (HCRU) for pts with NSCT MM receiving 1L LEN- or BORT-based regimens in 7 European countries. METHODS: Physicians from Austria, Belgium, France, Germany, Italy, Spain, and Netherlands abstracted retrospective data from medical records of pts with MM who received 1L LEN- or 1L BORT-based regimens between Jun 1 2015 and Nov 30 2016. Data were abstracted during Q1-2 2019 to allow adequate follow up time to assess outcomes of interest. Data collected included pt demographics, clinical characteristics, tx patterns, health outcomes (e.g. progression free survival [PFS], time to next tx [TTNT]), and HCRU (e.g. supportive tx, hospitalizations, healthcare professional [HCP] visits, monitoring tests). Health outcomes were compared for LEN- and BORT-based regimens using the Kaplan-Meier estimator. HCRU was calculated as means per month (mo), per usage type, to account for variation in tx duration. Patients with complete resource use data for an HCRU category were included in the analysis for that category. RESULTS: 59 physicians provided data on 453 pts. A total of 220 (48.6%) pts received 1L LEN- and 233 (51.4%) received 1L BORT-based regimens. The most common 1L LEN- and BORT-based regimens were LEN + dexamethasone (DEX; n = 194) and LEN + prednisone (PRED; n = 15), and BORT + melphalan + PRED (n = 94) and BORT + DEX (n = 82), respectively. Mean follow up time was similar for both regimens (38.2 vs 39.4 mo, respectively). Demographic profiles of pts receiving 1L LEN- or BORT-based regimens were similar (P > 0.05 for all demographic variables); time from diagnosis to start of 1L, performance status at first tx, comorbidities, CRAB criteria, bone lesions at diagnosis, or cytogenetic testing did not differ significantly. Within the follow up period, pts treated with 1L LEN-based regimens received significantly fewer lines of tx (mean [SD] 1.55 [0.64] vs 1.75 [0.69] lines; P < 0.01) vs pts treated with 1L BORT-based regimens. Of the 233 pts receiving 1L BORT-based regimens,142 went on to receive 2L tx, of whom 104 (73%) received a second-line (2L) LEN-based regimen. Of the 220 pts receiving 1L LEN-based regimens, 105 went on to receive 2L tx, of whom 50 (48%) received a 2L BORT-based regimen. Health outcomes: Significant differences in PFS (P < 0.01) were observed; the probability of maintaining PFS was higher for pts receiving 1L LEN- vs 1L BORT-based regimens at 12 (94% vs 85%) and 24 mo (76% vs 63%) post-1L initiation. A significantly longer TTNT (median 45.7 vs 36.5 mo; P < 0.01) was observed for pts receiving 1L LEN vs those receiving 1L BORT. A significantly longer time to third line (3L) tx was estimated for pts receiving 1L LEN- vs 1L BORT-based regimens: approximately 15% of 1L LEN pts had started 3L tx at 48 mo vs 22% of 1L BORT pts (P = 0.01). From a sequencing perspective, a trend toward longer time to 3L tx was observed for pts receiving 1L LEN followed by 2L BORT vs pts receiving 1L BORT followed by 2L LEN (P = 0.11). HCRU: Across the follow up period, no differences were observed, with low overall HCRU observed for each cohort. CONCLUSIONS: Following the approval of LEN in the 1L setting, physicians have more options when treating NDMM. The findings of this study suggest that in a real-world setting, health outcomes are significantly better for NSCT pts with NDMM who receive 1L LEN- vs 1L BORT-based regimens. A US claims database study also suggested that LEN-based tx is associated with longer TTNT (Chari A, et al Clin Lymphoma Myeloma Leuk). In this analysis, 1L LEN-based regimens extended the time to 3L tx, potentially delaying progression to use of and associated cost impact of expensive tx in later line settings. Longer duration on 1L tx may also be expected to reduce total per pt per mo (PPPM) costs, as reported by a US study (Arikian SR, et al. Curr Med Res Opin). In our study, routine tx-related HCP visits were not explicitly captured and so the data may not accurately reflect differences in HCRU for pts receiving 1L LEN- vs 1L BORT-based regimens. This study provides real-world evidence to support 1L LEN-based regimens as providing clinically meaningful benefits for pts.

Most malignant tumors of the penis are squamous cell carcinomas (SCC), being divided in 2 groups, one human papillomavirus (HPV)-related and another non-HPV-related, with lymphoepithelioma-like carcinoma (LELC) being one of the rarest HPV-related SCC. In this article, we report a case of a 50-year-old man who presented testicular swelling and pain for the past 3 months. A penile mass was identified, and the patient was submitted to a total penectomy. The penectomy specimen showed an ulcerated lesion at the glans reaching the cavernous bodies. Microscopic examination showed undifferentiated epithelial cells with syncytial growth pattern mix with a dense lymphoplasmacytic infiltrate, consistent with LELC. The tumor cells expressed p16 and all 3 different clones of PDL1 (22C3, SP263, and SP142). The patient is alive and well with a follow-up of 3 months. To our knowledge, this is the third LELC of the penis reported in literature and the first case reported with PDL1 expression.
