Abstract Background Urinary tract infections (UTIs) are associated with significant morbidity and economic burden. Nitrofurantoin (NFT) and fosfomycin are among the first-line treatments for uncomplicated UTI (uUTI) recommended by Infectious Diseases Society of America (IDSA) 2011 guidance. We used real-world data (RWD) to assess patterns of appropriate and optimal (AP&OP) and inappropriate or suboptimal (IA/SO) antibiotic (AB) prescribing (RX), and related healthcare resource use (HRU) and costs, in US uUTI patients with high-risk comorbid conditions. Methods This was a retrospective cohort study of RWD (IBM MarketScan, commercial/Medicare Supplemental claims January 1, 2014–December 31, 2017) in females ≥ 12 years of age with uUTI, who had an oral AB prescription ± 5 days of uUTI diagnosis (index date) and continuous health-plan enrollment ≥ 1 year pre-/post-index date. Patients were stratified into high-risk cohorts (Table 1) and by AB RX (AP&OP and IA/SO) during first uUTI episode (within 28 days of index). AP&OP RX followed IDSA guidance, IA RX did not; SO RX was considered a proxy for treatment failure (e.g., AB switch or a second UTI diagnosis [acute care setting] in index episode). Sample size was balanced via random match selection, AP&OP:IA/SO ratio 1:5 (age and region). uUTIrelated HRU and costs were compared between cohorts (at index episode and 1-year follow-up) via multivariable analysis. Table 1. High-risk cohorts identified in the study Results IA/SO AB RX was highest in the elderly cohort (94.3%, likely influenced by renal impairment/no NFT RX in this group) and > 90% in other cohorts; AP&OP AB RX was highest in the postmenopausal cohort (9.0%). IA/SO AB RX in all cohorts was associated with significantly higher uUTI-related HRU (outpatient visits and pharmacy claims) per index episode/during follow-up versus AP&OP AB RX (p ≤ 0.0237, Table 2). IA/SO AB RX in all cohorts was associated with significantly higher adjusted total costs per index episode/during follow-up versus AP&OP AB RX (p < 0.05; Table 3). Table 2. uUTI-related HRU* per patient according to high-risk cohort and stratified by AB RX Table 3. uUTI-related costs* per patient according to high-risk cohort and stratified by AB RX Conclusion Over 90% of females in each high-risk cohort identified had IA/SO AB RX (outside IDSA 2011 guidance for uUTI treatment), leading to high HRU and cost burden. This suggests an unmet need for uUTI symptom relief, new treatments, training, and improved RX practices in the US and, furthermore, a need for additional research in this area.

Abstract Background Urinary tract infections (UTIs) are associated with significant morbidity and economic burden, particularly in the elderly and patients with comorbidities. We used real-world data (RWD) to assess healthcare resource use (HRU) and costs in patients with uncomplicated UTI (uUTI) and high-risk comorbid conditions in the US. Methods This was a retrospective cohort study (IBM MarketScan RWD, commercial/Medicare Supplemental claims January 1, 2014–December 31, 2017) of females ≥ 12 years of age with uUTI who had an oral antibiotic prescription ± 5 days of uUTI diagnosis (index date) and continuous health-plan enrollment for ≥ 1 year pre-/post index date. Five high-risk cohorts and matched-control cohorts (baseline age, region) were identified: controlled type 2 diabetes (T2D), mild/moderate chronic kidney disease (CKD), recurrent UTI (rUTI), elderly (ELD), and postmenopausal (PMP) (Table 1). Sample sizes were balanced via random match selection (1:5 case:control). uUTI-related HRU and costs were compared between cases and controls (index episode/1-year follow-up) using multivariable generalized linear models. Table 1. Cohort assignment for high-risk cohorts and controls Results Of 339,100 patients with uUTI, case/control cohorts comprised T2D, n=15,423/n=77,115; CKD, n=1041/n=5205; rUTI, n=7937/n=39,685; ELD, n=23,666/n=118,330; and PMP, n=105,608/n=211,216 patients. HRU trends across cohorts varied. During 1-year followup, outpatient visits were significantly different for cases versus controls in the T2D, rUTI, and PMP cohorts (p ≤ 0.0079), with higher case than control values in the rUTI and PMP cohorts; pharmacy claims were significantly higher for rUTI, ELD, and PMP cases, and inpatient visits were significantly higher for ELD and PMP cases, versus controls (all p < 0.0001; Table 2). Adjusted total uUTI-related costs (emergency room + outpatient + pharmacy) were significantly different (p < 0.0001) for cases versus controls at index episode and during follow-up in all cohorts except CKD: case values were higher than controls at index episode and during follow-up in the T2D cohort, and during follow-up in the rUTI and ELD cohorts (Table 3). Table 2. uUTI-related HRU* for cases versus controls according to high-risk cohort Table 3. uUTI-related costs* for cases versus controls according to high-risk cohort Conclusion Females in some high-risk case cohorts had higher uUTI-related HRU and costs versus controls. Further studies of relationships between comorbidities and uUTI burden are needed. Disclosures Madison T.

Abstract Background Uncomplicated urinary tract infections (uUTI) are one of the most common bacterial infections in women. Understanding unmet needs of physicians in diverse healthcare systems is important for developing novel uUTI treatment (tx). Methods A cross-sectional survey of physicians in the US and Germany (DE). Physicians were recruited via specialist panel and the survey was piloted (1 US, 1 DE physician) prior to recruitment. Primary objectives were understanding physician tx goals, management approaches, and prescribing patterns for uUTI. Secondary objectives included understanding perceptions of uUTI impact on patients and awareness of antibiotic (AB) resistance. Descriptive statistics were used for analysis. See Table for inclusion/exclusion criteria. Table. Physician inclusion and exclusion criteria Results Overall, 300 physicians (200 US, 100 DE) were surveyed. Symptom relief was in the top 3 (of 5) most important outcomes for ≥ 90% of physicians (US and DE); clearing infection was a top 3 outcome for 85% of US and 60% of DE physicians (Fig. 1). Physicians estimated ~20% of patients do not achieve complete relief from initial AB tx. Generally, urinalysis, dip stick, and symptom review were most commonly used in diagnosis, with culture and AB susceptibility tests mostly used to aid tx decisions (Fig. 2). For first-line AB, US physicians reported trimethoprim-sulfamethoxazole (TMP-SMX; 76%) and nitrofurantoin (57%) as most prescribed; in DE, fosfomycin (61%) and TMP-SMX (50%) were prescribed most. In both countries, ciprofloxacin (US 51%, DE 45%) was most prescribed after ≥ 2 tx failures. On a scale of “very poor” (1) to “exceptional” (7) for tx and management of uUTI, 58% of US physicians gave TMP-SMX a 6 or 7, and 62% of DE physicians gave fosfomycin a 6 or 7. More than 33% of physicians believed patients’ quality of life was greatly impacted by 1 tx failure, rising to 60% of physicians for 2 tx failures, and 73% for ≥ 3. Most physicians (72% US, 83% DE) agreed that development of AB resistance was serious (Fig. 3), but fewer (56% US, 46% DE) were confident in their knowledge of AB resistance. Figure 1. Treatment goal considered in the top 3 most important goals by physicians for managing patients with uUTI Figure 2. Use of diagnosis (A) and treatment decision (B) aids Figure 3. Physicians’ opinions on antibiotic resistance Conclusion Symptom relief was the primary uUTI tx goal for physicians. Physicians recognized that patients are greatly impacted by tx failure and AB resistance is a serious problem, but many were not confident or had insufficient information on AB resistance.

Abstract Background Complicated urinary tract infections (cUTI) are one of the most common bacterial infections and represent substantial burden to the health care system. Here, we examine the epidemiology and treatment patterns associated with cUTI in a large US database containing longitudinal inpatient (IP) and outpatient (OP) patient-level data. Methods We conducted a retrospective cohort study of adult patients in the IBM MarketScan® Commercial or Medicare Supplemental Databases with at least 1 IP or non-diagnostic OP claim with a diagnosis for cUTI between January 1, 2017 and June 30, 2019. Patients meeting the following criteria were included for analysis: (1) ≥18 years of age on the index date, (2) ≥6 months of continuous enrollment (CE) with medical and pharmacy benefits prior to the index date, (3) ≥12 months of CE following the index date or evidence of death, and (4) no evidence of a prior cUTI during the 6-month baseline period. Demographics and clinical characteristics were quantified. Patients were classified as IP if they were hospitalized during 30-day post index date; remaining patients were classified as OP. Antibiotics received in the OP setting in the 12-months post index date were examined. Results 95,423 patients met study criteria. Most (86.4%) patients were Commercially insured, mean (SD) age was 53.6 (18.1) and 70.4% were female. Mean baseline Charlson Comorbidity Index was 0.77. During the 30-day post index date, 22.2% were treated as IP and 77.8% were strictly treated as OP. In the 12-month OP follow-up period among index IP, 78.2% required ≥ 2 antibiotics, 38.2% required ≥4 antibiotics, and 41.6% received an IV antibiotic. In the 12-month OP follow-up period among index OP, 81.8% required ≥2 antibiotics, 38.2% required ≥4 antibiotics, and 46.8% received an IV antibiotic. For both IP and OP, fluoroquinolones were the most common oral antibiotic class (57.7%), followed by cephalosporins (39.2%), penicillins (30.3%), trimethoprim-sulfamethoxazole (29.8%), and nitrofurantoin (25.2%). Cephalosporins were the most common IV antibiotic class (38.5%). Conclusion Regardless of index treatment setting, approximately 40% of all cUTI patients required ≥4 antibiotic therapy and almost half with receive an IV antibiotic in the outpatient setting in the 12-months post index date.

Background: There is a dearth of real-world evidence studies focused on allergy immunotherapy (AIT) use among patients with allergic rhinitis (AR). Objective: This study examined claims data of AR patients residing in the United States to assess patient characteristics and health outcomes. Methods: AR patients were identified in the IBM MarketScan database between January 1, 2014, and March 31, 2017. Patients receiving AIT were identified with relevant billing codes (earliest AIT claim for vaccine as the index date); patients without AIT were identified with claims that contained a diagnosis code for AR (earliest AR claim as the index date). All the patients were required to have continuous enrollment 12 months prior to and following their index date. AIT patients reaching 25+ injection claims were analyzed as a separate maintenance cohort. Patients were assessed for demographic characteristics, comorbid conditions, and health care utilization. Results: A total of 2,334,530 AR patients were included; 103,207 had at least one AIT claim, with 45,279 (43.9%) of these patients reaching maintenance. Patients who reached AIT maintenance presented higher rates of baseline comorbidities than both the full AIT cohort and the patients with no AIT claims, including asthma (34.6% versus 30.1% versus 7.5%) and upper respiratory tract infections (63.1% versus 60.3% versus 34.2%). From baseline to follow-up, maintenance AIT patients demonstrated reductions in all AR-related comorbidities assessed, along with reductions in all-cause and AR-related service utilization. Conclusion: Patients initiating AIT presented the greatest need for therapeutic intervention, as evidenced by higher allergy-related comorbidities; those who reached maintenance demonstrated improved outcomes following the initiation of therapy. Continued efforts to increase patient awareness and adherence to AIT are needed.

Abstract Background Urinary tract infections (UTIs) disproportionately affect women and are a substantial burden on healthcare systems. We assessed the effect of antibiotic (AB) switching on UTI recurrence, healthcare resource use (HRU), and related costs among adolescent and adult females in the US with uncomplicated UTIs (uUTIs). Methods This retrospective cohort study used US Optum claims data (United Healthcare, January 1, 2013–December 31, 2018). Eligible patients were females ≥ 12 years of age with an acute uUTI diagnosis at outpatient or emergency department (ED) visit (index date) and an oral AB prescription within ± 5 days of index. Patients with recurrent UTIs (rUTIs), defined as 2 UTI diagnoses (including index) in 6 months or ≥ 3 UTI diagnoses (including index) in 12 months, were included; those with complicated UTI were excluded. Patients were assigned to two groups: AB switch (≥ 2 filled prescriptions of different AB within 28 days post index [uUTI episode]) and no AB switch. Results In 5870 eligible patients (mean age 44.5 years; 76.6% White), ciprofloxacin (CIP; 38.6%), nitrofurantoin (NFT; 31.4%), and trimethoprim-sulfamethoxazole (TMP-SMX; 25.6%) were the most commonly prescribed first-line ABs at index, and 567 (9.7%) patients switched AB. CIP was switched to NFT and TMP-SMX in 2.0% and 1.7% of patients, respectively. NFT was switched to CIP and TMP-SMX in 2.6% and 1.5% of patients, respectively. TMP-SMX was switched to CIP and NFT in 3.0% and 2.4% of patients, respectively. During index visit, the AB switch group had higher mean ambulatory care and pharmacy claims (both p < 0.001), and higher total mean HRU costs (&2186.4) per patient compared with the no switch group (&1508.8; p = 0.011). More patients had rUTI in the AB switch group (18.9%) versus the no switch group (14.2%; p < 0.001), and more had ED visits in the AB switch group than the no switch group (p < 0.0001) (Table 1). During follow-up, the AB switch group had a higher mean number of uUTI episodes per patient (p < 0.001; Table 1), and more patients had UTI-related ED visits (10.8%) compared with the no switch group (7.7%; p = 0.010; Table 2). Table 1. Primary outcomes of uncomplicated UTI outpatients during January 1, 2013–December 31, 2018, stratified by any switch in AB use during index episode Table 2. Primary outcomes of uncomplicated UTI outpatients during January 1, 2013–December 31, 2018, stratified by any switch in AB use during 12-month follow-up Conclusion US females with uUTI who switched AB had more rUTI cases and increased overall costs and HRU compared with those who did not switch AB, suggesting an unmet need for improved prescribing practices.

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.

Abstract Background Urinary tract infections (UTIs) are the most common outpatient infection requiring medical care in the US; but, despite Infectious Diseases Society of America 2011 guidelines for treating uncomplicated UTI (uUTI), variation in prescribing practices still exists. Few studies have used real-world data (RWD) to evaluate uUTI-associated healthcare resource use (HRU) and costs. We examined HRU and direct costs associated with appropriate and optimal (AP&OP) and inappropriate or suboptimal (IA/SO) antibiotic (AB) prescribing in females with uUTI using US RWD. Methods This retrospective cohort study used RWD from IBM MarketScan (commercial/Medicare claims) to examine uUTI-related HRU and costs (inpatient, emergency room, outpatient, pharmacy) per index uUTI episode and during 1-year follow-up among females (age ≥ 12 years) diagnosed with uUTI from July 1, 2013–December 31, 2017 (index date). Patients had an oral AB prescription ± 5 days of the index date, and continuous health plan enrollment ≥ 6 months pre/1 year post-index date; those with complicated UTI were excluded. Patients were stratified by AB prescription as follows: AP&OP = guideline-compliant and correct duration; IA/SO = guideline non-compliant/incorrect duration or re-prescription/switch within 28 days. Results The study included 557,669 patients. In the commercial population (n=517,664, mean age 37.7 years), fewer patients were prescribed AP&OP (11.8%) than IA/SO (88.2%) ABs, a trend also seen in the Medicare population (n=40,005, mean age 74.5 years). In both populations, adjusted average numbers of uUTI-related ambulatory visits and pharmacy claims were lower for the AP&OP cohort than the IA/SO cohort during index episode and 1-year followup (p < 0.0001, Table 1). In the commercial population, total adjusted uUTI-related costs were &194 (AP&OP) versus &274 (IA/SO; p < 0.0001); in the Medicare population, total adjusted uUTI-related costs were &253 (AP&OP) versus &355 (IA/SO; p < 0.0001) (Table 2). Table 1. uUTI-related HRU for commercial and Medicare populations calculated using the GLM model Table 2. uUTI-related costs for commercial and Medicare populations calculated using the GLM model Conclusion Overall uUTI-related HRU and costs in the US were low during index episodes and follow-up. However, females with uUTI prescribed IA/SO ABs were more likely to incur higher HRU and costs than those prescribed AP&OP ABs, suggesting an unmet need for training to optimize uUTI prescribing per US guidelines.

Abstract Background Despite well-established guidelines for urinary tract infection (UTI) treatment, prescribing practices vary. We examined the association between inappropriate (IA) or suboptimal (SO) antibiotic (AB) prescribing (RX) and hospitalization, healthcare resource use (HRU), and costs among patients with uncomplicated UTI (uUTI) in the US. Methods This retrospective cohort study used linked Premier Healthcare/Optum claims data from female outpatients (≥ 12 years old) with a uUTI diagnosis (January 1, 2013 to December 31, 2018). Patients with complicated UTIs (eg, urological abnormalities, medications/procedures associated with complicated UTI, or intravenous AB receipt at index) were excluded. HRU and costs between patients with IA/SO and appropriate and optimal (AP&OP) AB RX (defined in Table 1) were assessed from Optum claims data during index episode (within 28 days of index) and 12-month follow-up. Table 1. Definitions of appropriateness of AB RX Results Of 5870 patients, 1856 (31.6%) had IA and 1255 (21.4%) had SO AB RX. Patients with IA/SO AB RX (47.1%) were older and more likely to have a Charlson Comorbidity Index score > 0 than those with AP&OP AB RX (52.9%; Table 2). During index episode, mean ambulatory care and pharmacy claims were significantly higher for IA/SO versus AP&OP AB RX (8.0 vs 6.3, 3.3 vs 2.6, respectively; p < 0.01), and total HRU cost per patient was higher for IA/SO (&2616) versus AP&OP AB RX (&649; p < 0.01). During follow-up, 267 (9.7%) patients with IA/SO AB RX had a UTI-related emergency department (ED) visit versus 202 (6.5%) patients with AP&OP AB RX (p < 0.001). Mean UTI-related HRU costs were significantly higher for IA/SO (&5048) versus AP&OP AB RX (&3633; p = 0.01). After adjusting for patient characteristics, patients with IA/SO AB RX were 40% more likely than those with AP&OP AB RX to have a UTI-related ED visit (odds ratio 1.40; 95% confidence interval 1.15–1.71) during follow-up (Table 3). Adjusted HRU costs for IA/SO AB RX (vs AP&OP) were numerically higher for index uUTI episode (by &1772), and UTI-related (by &1102) and all-cause (by &1528) charges during follow-up (Figure).

Total 12-month UTI-related and all-cause visit charges (adjusted), stratified by appropriateness of AB RX at index and during follow-up Conclusion IA/SO AB RX was associated with higher overall and UTI-related HRU and costs during index episode and 12-month follow-up, highlighting a need for education on applying prescription guidelines and the use of culture-based RX.

OBJECTIVE OF THE STUDY SIDECAR (SGLT2-Inhibitors in Diabetes: Evaluation of metabolic Control and Adverse events in the Real-world), is a monocentric prospective observational study performed to monitoring in clinical practice patients with type 2 diabetes (T2D) treated with SGLT2-i to evaluate metabolic and anthropometric evolution during time, as well as the onset of adverse effects (AEs). Design and methods. Demographic features, T2D duration, and clinical parameters at baseline have been recorded as mean ± Standard Deviation (SD) for continuous variables, and frequency distribution for discrete variables. A repeated measures regression model was utilized for the evolution during time of parameters. AEs prevalence were recorded with stratification for main clinical and demographic features at baseline. RESULTS N=220 patients, with 18 months available follow-up, treated with SGLT2-i (N= 19 canagliflozin, 8.6%; N=91 dapagliflozin, 41.4%; N=110 empagliflozin, 50%) monotherapy or in combination according to AIFA indications). Really effective was the action of SGLT2-i on glucose  metabolism, with rapid reduction in HbA1c and fasting plasma glucose after 6 months, as well as after 12 and 18 months (HbA1c: -1,0%; fasting plasma glucose: -34,8mg/dL). Weight and BMI showed a satisfying improvement, while waist circumference was statistically significant only after 12 months. Blood pressure, total cholesterol, and renal function were not modified by the treatment. But, apart from the valuable effects on metabolic parameters, 86 patients (39%) suspended SGLT2-i treatment mainly because ineffectiveness (15,7%) or for Genito-Urinary Tract Infections (GUTIs) appearance (14,3%). CONCLUSIONS Median term follow-up confirms the efficacy of SGLT2-i, but a significant percentage of patients is forced to suspend these drugs especially for GUTIs appearance. Such high prevalence of non-serious AEs limits the potential nephro-cardiovascular benefits related to SGLT2-i utilization. A possible chance to reduce GUTIs should come from single tablet association of SGLT2-i and DPP4-i actually available on the market.

Background: Patients with classical Hodgkin lymphoma (cHL) relapsed or refractory (R/R) disease who relapse after or are ineligible for autologous stem cell transplantation have a poor prognosis. Recently, the anti-PD1 monoclonal antibodies nivolumab and pembrolizumab were approved by the FDA (May 2016 and March 2017, respectively) as treatment options for R/R cHL patients. In the absence of head-to-head clinical trials, observational data may provide hypothesis-generating insight into the real-world outcomes of patients receiving these PD-1 inhibitors. This study aims to evaluate healthcare resource utilization (HRU) among patients with cHL initiated on pembrolizumab compared to nivolumab in the United States. Methods: A retrospective database analysis was conducted using Symphony Health's Patient Integrated Dataverse® (07/2014-06/2018). The date of the first dispensing or administration of pembrolizumab or nivolumab was assigned as the index date. Patients who received both treatments and who initiated nivolumab prior to pembrolizumab approval, or in the first months after, were classified in the pembrolizumab cohort. Included patients were required to meet the following criteria: ≥12 months of continuous clinical activity prior to the index date, ≥1 inpatient or ≥2 outpatient visits with a cHL diagnosis prior to the index date, no diagnosis of nodular lymphocyte-predominant Hodgkin lymphoma, and ≥18 years of age at the index date. Baseline patient characteristics were assessed in the 12-month baseline prior to the index date. Inverse probability of treatment weighting (IPTW) based on the propensity score was used to adjust for observed differences in baseline covariates between cohorts. Rates per person-year (PPY) of all-cause and cHL-related (i.e., visits with a primary or secondary diagnosis of cHL) HRU were calculated for weighted cohorts during the follow-up period, which spanned from the index date to the end of clinical activity or data availability. Rates of HRU were compared using rate ratios (RRs) from Poisson regression models. Results: A total of 92 patients initiated on pembrolizumab and 218 patients initiated on nivolumab met the selection criteria and were included in the analysis. Of the 92 pembrolizumab patients, 6 patients received nivolumab during the baseline period. After weighting, the mean age was similar at 55 years in both cohorts, while the proportion of female was lower in the pembrolizumab cohort (35.3%) compared to the nivolumab cohort (44.1%; standardized difference [StD]=17.9%). The mean (median) follow-up period was 295 (264) days for pembrolizumab users and 274 (208) days for nivolumab users (StD=9.4%). Mean Quan-Charlson Comorbidity Index score was well balanced after weighting in the pembrolizumab and nivolumab cohorts (4.2 and 4.3, respectively; StD=2.2%); 13.8% and 15.0% had depressive disorders (StD=3.7%), and 8.5% and 10.2% had substance-related and addictive disorders (StD=5.8%), respectively. The mean number of baseline hospitalizations (pembrolizumab=1.6, nivolumab=1.5; StD=3.1%) was also well balanced after weighting. The total person-time of observation was 74.6 and 163.6 years for the weighted pembrolizumab and nivolumab cohorts, respectively. Over this period, patients in the pembrolizumab cohort had significantly lower rates of all-cause hospitalizations (0.46) PPY than those in the nivolumab cohort (1.39; RR [95% confidence interval, CI]=0.33 [0.09-0.80], P=0.014; Figure). Furthermore, the rate of cHL-related hospitalizations PPY was significantly lower in the pembrolizumab cohort (0.06) compared to the nivolumab cohort (0.42; RR [95% CI]=0.14 [0.02-0.37], P<0.001; Figure). A similar trend (i.e., ratio below 1) was observed for all-cause and cHL-related outpatient visits, but the difference was not statistically significant (all-cause RR [95% CI]=0.84 [0.56-1.11], P=0.200; cHL-related RR [95% CI]=0.90 [0.47-1.42], P=0.647). Conclusion: In this real-world study, adult cHL patients treated with pembrolizumab had significantly lower rates of all-cause and cHL-related hospitalizations than those treated with nivolumab. Fewer all-cause and cHL-related outpatient visits were also observed among pembrolizumab users. Additional research is warranted to further investigate these early trends in real-world HRU observed among patients with cHL receiving anti-PD1 therapies.
