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.

Introduction: Previous studies have examined the total healthcare resource utilization (HCRU) of patients with beta-thalassemia in relation to the general population. However, limited studies have examined the impact of red blood cell transfusion (RBCT) burden on broad aspects of HCRU beyond transfusion costs among patients with beta-thalassemia. Methods: Patients with beta-thalassemia in Taiwan's National Health Insurance Research Database (NHIRD) in 2016 were identified (International Classification of Diseases, Tenth Revision, Clinical Modification [ICD-10-CM] of D56.1). The index date was the first medical claim in the database after 2001. Identified patients were followed from the index date until the end of the study period (December 31, 2016). During the follow-up period, RBCT units and HCRU (all-cause and thalassemia-related) were measured. Thalassemia-related HCRU was defined as any HCRU claim accompanied by a thalassemia or beta-thalassemia diagnosis code. To control for the different lengths of follow-up between patients, both RBCT units and HCRU were reported as the average per 12 weeks over the entire follow-up period. Patients were categorized into 4 cohorts based on the average number of RBCT units received per 12 weeks during follow-up: 0 RBCT units; > 0 to < 6 RBCT units; ≥ 6 to < 12 RBCT units; or ≥ 12 RBCT units. HCRU outcomes of interest were hospital admissions, hospitalized days, outpatient visits, and emergency room (ER) visits. Descriptive statistics were computed to describe HCRU observed in each cohort. Results: A total of 2,984 patients with beta-thalassemia were included in the analysis, with a mean follow-up of 6.87 years. Mean age at index was 37.8 (standard deviation 23.7) years, and 1,903 (63.8%) patients were female. A total of 1,616 (54.2%) patients did not receive RBCT units during the follow-up period. Of the remaining 1,368 patients, 1,112 (81.3%) received > 0 to < 6 RBCT units, 112 (8.2%) received ≥ 6 to < 12 RBCT units, and 144 (10.5%) received ≥ 12 RBCT units per 12 weeks during follow-up. Mean all-cause and thalassemia-related HCRU was higher for transfused patients than for non-transfused patients across all HCRU categories. Thalassemia-related hospital admissions, hospitalized days, and outpatient days all increased as the transfusion burden increased. Patients in the cohort with the highest average transfusion burden (≥ 12 RBCT units per 12 weeks) had numerically greater mean thalassemia-related hospital admissions (0.5; standard error [SE] = 0.04), hospitalized days (2.5; SE = 0.21), and outpatient visits (4.9; SE = 0.41) than the other cohorts (Figure). Conclusions: Patients with beta-thalassemia and higher average transfusion burden during the follow-up period had additional HCRU compared with patients who required fewer RBCT units. These data may support physician and payer understanding of the downstream economic impact of RBCT burden in beta-thalassemia.

Introduction : Flow diversion has established itself as standard treatment of wide complex intracranial aneurysms (IA). Its recognition has been validated with positive occlusion rates and favorable clinical outcomes. The Surpass Streamline (SS) flow diverter (FD) is a braided cobalt/chromium alloy implant with 72 or 96 wires approved by the FDA in 2018. The aim of this study is to determine the safety and efficacy of the SS in a post‐marketing large US cohort. Methods : We performed a multicenter, retrospective study for consecutive patients treated with the SS FD for IA between January 2018 and June 2021 in the United States. Inclusion criteria for participants were: 1. Adults (≥ 18 years) and 2. Treatment with SS FD for IA. Primary safety end point was a major ipsilateral stroke (increase in National Institutes of Health Stroke Scale Score of ≥ 4) or neurological death within 12 months. Primary efficacy was assessed using the 3‐point Raymond‐Roy (RR) occlusion scale on digital subtraction angiography (DSA) at 6‐12‐month follow‐up. Results : A total of 276 patients with 313 aneurysms were enrolled. The median age was 59 years and 199 (72%) were females. The most common comorbidities included hypertension in 156 (57%) subjects followed by hyperlipidemia in 76 (28%) patients. One hundred and twenty‐two (44%) patients were asymptomatic while subarachnoid hemorrhage was present in only 10 (4%) patients. A total of 143 (46%) aneurysms were left‐sided. Aneurysms were located as follows: 274 (88%) were in the anterior circulation with paraophthalmic being the most common in 120 (38%) followed by petrocavernous ICA in 81 (26%); 33 (11%) aneurysms were located in the posterior circulation with basilar trunk being the most common in 14 (5%). The mean maximum aneurysm dome width was 5.77 ± 4.7 mm, neck width 4.22 ± 3.8 mm and dome to neck ratio was 1.63 ± 1.3 mm. The mean number of SS FD implanted per aneurysm was 1.06 (range 1–3) with more than one SS FD implanted in 21 (7%) aneurysms. Modified Rankin Scale (mRS) of 0–2 was present in 206/213 (97%) patients at 6–12 month follow‐up. The complete aneurysm occlusion (RR 1) rate was 145/175 (83%) among subjects who had angiographic follow‐up at 6–12 months. Major stroke and death was encountered in 7 (2%) and 5 (1.8%) of the patients respectively. Conclusions : Our data represent the largest real‐world study using SS FD. These results corroborate its post‐marketing safety and efficacy for the treatment of intracranial aneurysms showing more favorable rates to the initial experience during SCENT trial.

Abstract Introduction Mantle cell lymphoma (MCL) is a rare, aggressive non-Hodgkin lymphoma associated with a poor prognosis. The approval of ibrutinib in November 2013 has changed the treatment paradigm for patients with relapsed or refractory MCL. There remains a lack of information on the current treatment patterns used in clinical practice in a contemporary cohort of commercially insured patients. We aimed to identify the treatment patterns for MCL overall and by line of therapy (LOT) and to describe patient demographics and clinical characteristics in a large cohort of commercially insured MCL patients. Methods A retrospective cohort study was conducted with the IQVIA Real-World Data Adjudicated Claims-US database. Adult patients (≥18 years old) with ≥1 claim for a NCCN-recommended MCL treatment between November 1, 2013 and December 31, 2017 were identified. Index date was the first treatment claim. Patients were also required to have ≥1 diagnosis of MCL during the study period (November 1, 2012 to January 31, 2018), ≥12 months of continuous enrollment prior to index date (pre-index period) and ≥30 days after index date (follow-up period). Patients were excluded if they were ≥65 years at index and not enrolled in Medicare Risk or Medicare Cost, enrolled in a clinical trial during the study period, had evidence of MCL treatment in the pre-index period (except for patients indexed on ibrutinib as it is indicated for MCL patients with ≥1 prior treatment), or had evidence of stem cell transplant (SCT) before index date. The most commonly observed MCL treatment regimens were identified, and demographic and clinical characteristics of patients and treatment durations by regimen were described. Treatment regimen was defined as the combination of all agents observed in the 35-day period after the first MCL treatment claim; treatment duration was defined as the start of treatment until a gap of ≥90 days between end date and next date of treatment or treatment modification. Treatment end date occurred 90 days after the end of the supply for oral medications or 30 days after the last administration for non-oral medications. Results There were 1,785 patients treated with the most commonly observed MCL treatment regimens. The most common regimens, irrespective of LOT, were rituximab monotherapy (including maintenance therapy; n=773, 43.3%), R-CHOP (n=723, 40.5%), B-R (n=436, 24.4%), and ibrutinib monotherapy (n=199, 11.1%). Overall, patients had a median (IQR) age of 57 (52-62) years, and 59.4% were male. Most patients were commercially or self- insured (57.5% and 33.6%, respectively). Patients had a median Charlson Comorbidity Index (CCI) of 0 (IQR 0-1; mean [SD] 0.9 [1.4]), with the most common CCI components being diabetes (15.7%), chronic pulmonary disease (12.8%), and congestive heart failure (9.5%). During the follow-up period (median [IQR] 22.5 [10.5-35.3] months), in addition to the MCL regimen(s), patients received radiation therapy (17.4%), SCT (10.0%), and/or immunotherapy (0.2%). The use of targeted therapies (i.e. lenalidomide, bortezomib) other than ibrutinib was infrequent. When considering treatment lines, R-CHOP was the most commonly observed first regimen, followed by rituximab, B-R, and ibrutinib; for the second and third observed regimens, rituximab was the most common, followed by ibrutinib (Figure 1). The median (IQR) duration for the first observed regimen was 8.1 (3.9-18.0) months for ibrutinib, 5.0 (3.3-5.6) months for B-R, 4.0 (2.5-4.4) months for R-CHOP, and 1.9 (1.7-4.4) months for rituximab; ibrutinib also had the longest duration in the second and third line (median [IQR] 5.5 [2.4-13.5] months and 8.3 [3.9-12.4] months, respectively). Conclusion This is the largest study of MCL patients describing treatment patterns in current clinical practice among commercially insured patients. MCL patients were most commonly treated with chemoimmunotherapy for all treatment lines while ibrutinib was the second most common LOT2 and LOT3 regimen. As the treatment landscape and clinical practice continues to change with the use of novel agents, future studies are warranted to further study toxicities and outcomes in the real-world setting.

Abstract OBJECTIVES: The purpose of this study was to examine real-world differences in healthcare resource utilization of indolent non-Hodgkin's Lymphoma (iNHL) patients treated with first-line ibrutinib monotherapy (IM) or first-line bendamustine + rituximab (BR) combination therapy using U.S. administrative claims data. METHODS: The MarketScan® Research Databases were used to identify patients aged 18 years or older with commercial or Medicare supplemental insurance plans based on their first prescription (index date) of either IM or BR therapy between 02/01/2014 and 08/30/2017. Patients were required to be diagnosed with iNHL and be treatment naïve, as well as be continuously enrolled (CE) for 6 months prior to and at least 30 days following the index date. All-cause and iNHL-related healthcare resource utilization (e.g., inpatient admission (IP) and emergency room (ER) visits) were evaluated during a 12-month follow-up period from the index date among the subset of patients with 12 months of continuous enrollment and reported per-patient per-month (PPPM). Statistical differences in the distribution of IP and ER visits between the IM versus BR therapy groups were estimated using chi-squared test for categorical variables and t-test for continuous variables. RESULTS: A total of 1,544 iNHL patients were identified, with 207 patients in the IM cohort and 1,337 patients in the BR cohort. The IM cohort was significantly older (mean = 68.3 years; SD = 11.8) then the BR cohort (mean age = 62.1 years; SD = 11.1). The proportion of females was significantly (p<.05) lower in the IM cohort (36%) relative to the BR cohort (49%). The two cohorts did not differ in comorbidity as assessed by National Cancer Institute Comorbidity Index score (IM=0.7 vs. BR=0.8, p=0.40). The results of the comparisons between the two groups with 12 months of follow-up (IM = 110; BR = 745) are provided in Table 1. For all-cause healthcare utilization, the proportion of IM patients experiencing at least one IP admission was significantly higher than the BR cohort as were the PPPM number of admissions. The proportion of patients with at least one ER visit was similar in the IM and BR cohorts. However, the average PPPM number of ER visits was significantly higher in the IM cohort relative to the BR cohort. A similar pattern was found for the iNHL-related healthcare utilization variables with one exception. The proportion of patients with at least one iNHL-related ER visit was significantly higher in the IM relative to the BR cohort. Conclusions: The current study examined differences in healthcare utilization among iNHL-patients treated in a front-line setting with either ibrutinib or BR combination therapy. Results indicated that not only did more ibrutinib patients experience an IP admission and ER visits, including both all-cause and iNHL-related, but they also experienced more repeat admissions and ER visits. These real-world findings highlight the importance of considering the healthcare resource utilization of iNHL patients which may be associated with their first-line therapy.

Abstract OBJECTIVES: The purpose of this study was to examine the real-world differences in healthcare resource utilization in chronic lymphocytic lymphoma (CLL) patients treated with either first-line ibrutinib monotherapy (IM) or first-line bendamustine + rituximab (BR) therapy using U.S. administrative claims data. METHODS: The MarketScan® Research Databases were used to identify patients aged 18 years or older with commercial or Medicare supplemental insurance plans based on their first prescription (index date) of either IM or BR therapy between 02/01/2014 and 08/30/2017. Patients were required to be diagnosed with CLL and be treatment naïve, as well as be continuously enrolled (CE) for 6 months prior to and at least 30 days following the index date. All-cause and CLL-related healthcare resource utilization (e.g., inpatient admission (IP) and emergency room (ER) visits) were evaluated during a 12-month follow-up period from the index date among the subset of patients with 12 months of continuous enrollment and were reported per-patient per-month (PPPM). Statistical differences in the distribution of IP and ER visits between the IM versus BR therapy groups were estimated using chi-squared test for categorical variables and t-test for continuous variables. RESULTS: A total of 1,886 CLL patients were identified, with 1,157 patients in the IM cohort and 729 patients in the BR cohort. The IM cohort was significantly older (mean = 69.3 years; SD = 11.6) then the BR cohort (mean age = 66.4 years; SD = 9.8). There was a similar proportion of females (IM = 36%; BR = 32%), and no significant difference in the National Cancer Institute Comorbidity Index score was observed between the two cohorts (IM=0.9 vs BR=0.8, p=0.34). The results of the comparisons between the two groups with 12 months of follow-up (IM = 589; BR = 436) are provided in Table 1. For all-cause healthcare utilization, the proportion of patients experiencing at least one IP admission and the PPPM number of admissions was significantly higher in the IM cohort compared to the BR cohort. The proportion of patients with at least one ER visit was higher in the IM than in the BR cohort, but the difference was not statistically significant. However, the PPPM number of ER visits was significantly higher in the IM cohort. A similar pattern was found for the CLL-related healthcare utilization variables with two exceptions. First, the average length of stay (ALOS) per CLL-related IP admission was significantly longer for the IM than BR cohort; whereas, ALOS per all-cause IP admission was longer for the IM cohort, but the difference was not significantly different. Second, while patients in the IM cohort experienced more CLL-related ER visits, they were not significantly higher in the IM cohort than in the BR cohort. Conclusions: The current study examined differences in healthcare utilization during a 12 month period among CLL-patients initially treated in a front-line setting with either ibrutinib or BR combination therapy. Results indicated that not only did more ibrutinib patients experience an IP admission and ER visits, both all-cause and CLL-related, but they also experienced more repeat admissions and ER visits. These real-world findings highlight the importance of considering the healthcare resource utilization of CLL patients which may be associated with their first-line therapy.

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 &gt; 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 &lt; 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 Sickle cell disease (SCD) is an autosomal recessive disorder characterized by abnormal hemoglobin. SCD causes hemolytic anemia, vaso-occlusion leading to vaso-occlusive crises (VOC) and contributing to organ damage and early death. SCD is most prevalent in sub-Saharan Africa and the Middle East, but also countries such as Brazil, India and US, have comparatively high frequencies of SCD. Global migration has contributed to a greater geographical spread. The prevalence of SCD in Sweden is unknown. OBJECTIVE The primary objectives of this study were to estimate the 1-year prevalence of SCD and SCD-associated resource use in Sweden. Secondary objectives were to estimate birth incidence, treatment patterns and survival. PATIENTS Patients with an ICD-10 diagnosis code for SCD (any D57 [excluding D57.3, sickle cell trait]) were identified from the Swedish Patient Registry (between January 1 st 2001 and June 30 th 2018). Patients were assessed for 1-year prevalence and resource use per calendar year for a follow-up period of 13 years (2006-2018). METHODS Patients were considered prevalent from birth or immigration to death or emigration. Resource use from specialized care, including all events recorded in the registry with any D57 as the main diagnosis was assessed in the follow up period 2006-2018 as number of outpatient visits and inpatient stays. Costs for this hospital resource use were estimated through remuneration amounts based on diagnosis related groups. Data on sick leave days and days with disability pension due to SCD in patients in working age (18-65 years) were retrieved from the Swedish Social Security Agency and costed with the mean salary in Sweden, plus social security contributions. Costs are reported in 2019 Swedish Krona (SEK, ≈$ 0.1). RESULTS One-year prevalence of all SCD diagnosis increased from 504 patients (5.53 per 100,000 population) in 2006 to 670 patients (6.55 per 100,000 population) in 2018. The 1-year prevalence of SCD patients ever recorded with an ICD-10 code for SCD with VOC (D57.0) increased from 139 patients (1.53 per 100,000 population) in 2006 to 260 patients (2.54 per 100,000 population) in 2018. The proportion of prevalent patients that were born in Sweden decreased over the years, from approximately 55% in the beginning of the study period to 45% in the end of the study period. The mean and median age of the SCD population decreased over the study period. Individuals with SCD and VOC were, on average younger than the other SCD (D57) subgroups. Birth incidence was captured by calendar year 2006-2018 and was highest in 2007 with 15 children born with SCD. For Swedish-born children with SCD during the patient identification time (n=123), the mean time to identification in the registers was 2.6 years (SD 2.7, range 0-16 years). Hospital outpatient visits and inpatient stays with SCD (all events with D57 recorded) as main diagnosis increased from 57 to 189, and 250 to 1,003, respectively, over the years 2006-2018. This corresponded to costs of inpatient care increasing from 1.4 million (M) SEK in 2006 to 7.3 M SEK in 2018 and costs of outpatient visits increasing from 0.9 M SEK in 2006 to 4.6 M SEK in 2018. The vast majority of costs were incurred in individuals ever recorded with a SCD with VOC diagnosis (D57.0). The most frequent hospital treatment was blood transfusion, with 8-11% of patients receiving transfusion in each year studied, especially common in SCD and VOC diagnosis. The prescribed treatment with the highest increase of uptake over the study period were hydroxyurea, vitamins and paracetamol in all SCD. Individuals in working age had on average 2.3 days of sick leave per patient-year due to SCD (D57), and approximately 4% of these patients received disability benefits because of their SCD. During the follow-up period, the median age at death was 74 years for all SCD and 69 years for SCD with crisis, this is 7-10 years and 12-15 years less compared to the Swedish general population respectively. CONCLUSION This study demonstrates that the prevalence, hospital resource use and associated costs have increased substantially in Sweden. In an era of emerging treatments for SCD we have for the first time comprehensively described epidemiological-, disease-related and economical aspects of SCD in Sweden.

Abstract Background/AimsThe study evaluated the real-world treatment outcomes of Glecaprevir/pibrentasvir (GLE/PIB) including effectiveness, safety and healthcare resource utilization based on a nation-wide registry in Taiwan.MethodsThe Taiwan HCV Registry (TACR) is a nation-wide platform organized and supervised by the Taiwan Association for the Study of the Liver. Data were analyzed for patients treated with GLE/PIB, including 3,144 patients who had treatment outcome available. The primary endpoint was sustained virological response (SVR12, undetectable HCV RNA throughout 12 weeks of end-of-treatment). ResultsThe overall SVR12 rate was 98.9% (3110/3144), with 98.8%, 99.4% and 100% in patients receiving 8 weeks, 12 weeks, and 16 weeks of GLE/PIB respectively. The SVR12 rate in the treatment-naïve cirrhotic patients receiving 8 weeks of GLE/PIB was 98.2% (108/110). The most common AEs were fatigue (7.5%), pruritus (6.7%) and dizziness (1.5%). The mean number of outpatient visits during the GLE/PIB was 5.94 visits for patients treated with 8 weeks, significantly different from the patients treated with 12 weeks of GLE/PIB (6.90 visits). ConclusionsThe results support the effectiveness and safety of GLE/PIB treatment in real-world clinical practice, and provide further evidence that the shorter, 8-week GLE/PIB regimen is effective and cost-saving.
