Abstract
INTRODUCTION This retrospective cohort study (GSK213737) aimed to characterize treatment patterns, healthcare resource utilization (HCRU), and costs in patients with lupus nephritis (LN) initiating immunosuppressant therapy in clinical practice in Germany, to better understand the full picture of the real-world burden of LN. METHODS Adult patients with LN who initiated mycophenolate mofetil (MMF), intravenous cyclophosphamide (CYC), azathioprine (AZA), tacrolimus, cyclosporin A, or rituximab therapy in 2011-2017 (index therapy) were identified from the Betriebskrankenkassen German Sickness Fund database. Treatment patterns, including immunosuppressant discontinuations, and therapy switches, were assessed (maximum follow-up 4 years). Corticosteroid use, HCRU, and total economic costs were also evaluated. HCRU and costs were compared with matched controls (individuals without systemic lupus erythematosus [SLE]/LN matched by age, sex, and baseline Charlson Comorbidity Index). RESULTS Among 334 patients with LN, the median (interquartile range) duration of index immunosuppressant therapy use was 380.5 (126, 1064) days. Of those patients with 4 years complete enrollment, 70.8% had ≥ 1 discontinuation and 28.8% switched therapy. While most patients (71.2%) received only one immunosuppressant, gaps in treatment were common. After 1 year of follow-up, 41.6% of patients had a prednisone-equivalent corticosteroid dose of ≥ 7.5 mg/day. Patients with LN had greater HCRU use for most categories assessed and increased mean total costs per person-year versus controls (€15,115.99 versus €4,081.88 in the first year of follow-up). CONCLUSIONS This real-world analysis demonstrated the considerable burden of immunosuppressant-treated LN in Germany, with a high rate of discontinuations, frequent use of high-dose corticosteroids, and substantial HCRU/costs.

Abstract
INTRODUCTION Lupus nephritis (LN) treatment aims to control and prevent flares and irreversible kidney damage. Around 30% of patients are unresponsive to treatment; however, real-world LN treatment patterns have not been reported. Objectives of this retrospective cohort study (GSK 209758) were to quantify the time to switching/re-initiating induction therapy in patients with LN initiating immunosuppressant therapy and conversion from induction to maintenance immunosuppressant therapy, and to assess corticosteroid use. METHODS Patients with LN initiating induction or maintenance immunosuppressant therapy were identified using claims data. Patients were followed up from the index date (immunosuppressant initiation date) until treatment discontinuation, death, disenrollment, administrative censoring, or the end of follow-up period. The cumulative incidence of switching/re-initiating induction therapy and conversion to maintenance therapy was estimated using outpatient pharmacy claims and procedure codes. Corticosteroid use was estimated using pharmacy claims; a mean daily dose of ≥ 7.5 mg/day was considered high. RESULTS In total, 5000 patients with LN contributed 5516 treatment episodes (induction cohort, N = 372; maintenance cohort, N = 5144). In the induction cohort, the cumulative incidence (95% confidence interval) of switching between induction therapies was 24.6% (20.1-30.0) at 12 months, while 59.6% (52.4-66.1) of patients converted to maintenance therapy at 12 months. In the maintenance cohort, 21.2% (19.9-22.5) re-initiated induction therapy at 12 months. Oral corticosteroid use decreased during the follow-up in both cohorts, but 21.5% of patients remained on a high dose at 12 months in the induction cohort, while 15.8% in the maintenance cohort were taking a high dose at 24 months. CONCLUSIONS Around a quarter of patients with LN initiating immunosuppressant therapy switched within 12 months, while a fifth re-initiated induction therapy within 12 months. Use of high corticosteroid doses were observed during 24 months of follow-up. These data suggest that many patients do not respond to existing standard LN therapies.

Abstract
Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can lead to irreversible organ damage (OD). Data describing the patient burden of OD, as compared with SLE without OD, are limited. Objective: To develop a comprehensive conceptual model describing the burden experienced by patients living with SLE-associated OD. Methods: There were three phases to this qualitative study. First, a targeted literature review was conducted to inform a draft conceptual model. Second, key opinion leaders (KOLs) were interviewed to assess the draft conceptual model and help shape patient interview materials. Third, patients of different demographic backgrounds from across the United States were interviewed individually to gather their perspectives on living with SLE-associated OD. Data from concept elicitation interviews with KOLs and patients were coded and analyzed using NVivo software to identify the key concepts of the overall patient burden of SLE-associated OD. Findings from the KOL and patient interviews were used to finalize the conceptual model. Results: KOLs highlighted that SLE-associated OD carried a higher rate of mortality than SLE alone. Participants with SLE-associated OD (n = 40) experienced detrimental impacts across 4 areas of their lives: physical, cognitive, psychosocial functioning, and economic and work-related well-being. Physical impacts were described by all participants, often affecting their ability to perform everyday tasks. Many also described deterioration of cognitive functioning. Almost all participants experienced emotional impacts and challenges to their relationships and social lives resulting from living with SLE-associated OD. Additionally, SLE-associated OD imposed an economic burden including increased healthcare costs. SLE-associated OD had a more severe and debilitating impact on all aspects of the patient's quality of life than SLE prior to OD development, including further limitations in activities of daily living after the development of OD. Discussion: Study findings guided the development of a comprehensive conceptual model that fully represents the patient experience of living with SLE-associated OD, highlighting the additional burden of OD when compared with SLE alone. Conclusions: The conceptual model will inform improvements in disease management, which may result in better patient outcomes and aid development of clinical outcome assessments of disease burden.

Abstract
INTRODUCTION The Profile of Fatigue and Discomfort-Sicca Symptoms Inventory-Short Form (PROFAD-SSI-SF) is a 19-item patient-reported outcome (PRO) measure to assess pain, fatigue, and dryness in patients with primary Sjögren's syndrome (pSS). This analysis identified concepts important to measure, and evaluated the content validity and measurement properties of the PROFAD-SSI-SF, in patients with pSS. METHODS Qualitative analyses (GSK Study 208396) used transcripts from an online concept elicitation (CE) discussion forum with patients with pSS and interviews with key opinion leaders (KOLs) to finalize a disease model depicting important concepts for patients with pSS. Cognitive debriefing (CD) interviews with patients with pSS were conducted to further evaluate the content validity of the PROFAD-SSI-SF. Quantitative analyses (GSK Study 213253) used post hoc analyses of blinded data from a phase 2 trial to assess PROFAD-SSI-SF measurement properties. RESULTS The CE discussion forum (N = 46) revealed dryness (oral 87.0%, ocular 73.9%, cutaneous 37.0%, vaginal 23.9%, nasal 15.2%, otic 6.5%), pain (89.1%), and fatigue (87.0%) as the most reported symptoms. KOLs (N = 5) found the concepts identified in the disease model accurate and understandable, and confirmed that PROs used in pSS studies should focus on dryness, joint pain, and fatigue. In the CD interviews (N = 20), of the 19 participants asked, all found the PROFAD-SSI-SF easy to understand, and 14/19 items were considered relevant by ≥ 18/20 participants. The quantitative analyses found an acceptable fit of the PROFAD-SSI-SF factor structure, with adequate internal consistency, test-retest reliability, convergent validity with other PRO measures, known-groups validity with Patient Global Assessment, and ability to detect change in patients with pSS. CONCLUSION The final disease model confirmed that the PROFAD-SSI-SF assesses concepts that are relevant and important to patients with pSS. Our findings support the content validity and measurement properties of the PROFAD-SSI-SF as a fit-for-purpose PRO measure appropriate for use in clinical trials in patients with pSS. CLINICAL TRIAL REGISTRATION NUMBER FOR THE PHASE 2 TRIAL: Clinicaltrials.gov NCT02631538.

Abstract
OBJECTIVE Glucocorticoids are part of standard therapy for systemic lupus erythematosus (SLE), despite adverse effects associated with long-term treatment. Belimumab improved clinical manifestations of SLE and reduced glucocorticoid doses in clinical trials and clinical practice; however, associations have not been examined using multi-institutional electronic health record (EHR) data. Using the Rheumatology Informatics System for Effectiveness registry, we examined glucocorticoid use patterns among belimumab-treated adults with SLE. METHODS This retrospective analysis (GSK Study 209267) used EHR prescription records of patients with SLE managed by rheumatologists. Eligible patients had an index date (first belimumab prescription) between January 2014 and June 2018. The primary analysis compared patients' mean daily oral glucocorticoid (prednisone equivalent) dose over the 6 months preindex versus 6 months post index. An exploratory analysis assessed glucocorticoid doses at 12 and 24 months post index for patients with extended follow-up. RESULTS Of the 1987 patients receiving their first belimumab prescription, 767 had available glucocorticoid prescribing data, whereas 204 (primary analysis population) had glucocorticoids prescribed in the 6 months preindex and received belimumab according to the prescribing information for the first 8 weeks post index. The mean (SD) glucocorticoid dose was 12.5 (13.5) mg/day 3 months preindex, reducing to 10.3 (10.6) mg/day over the 6 months post index, and 8.7 (9.4) and 9.0 (9.3) mg/day at 12 and 24 months post index. CONCLUSION This study showed reductions in mean daily glucocorticoid dose after belimumab initiation. Several limitations of EHRs for real-world effectiveness research were identified, which limited interpretation of results and may inform future study designs.

Abstract
Introduction Lupus nephritis (LN) is more prevalent in patients with SLE of Asian ethnicity than in Caucasian patients. Belimumab became available in Japan in 2017 to treat patients with SLE, including those with LN. In the BLISS-LN trial (NCT01639339), belimumab showed a favourable effect on renal outcomes when combined with standard therapy (ST) starting at the induction treatment phase for active LN, but real-world effectiveness of belimumab in LN has not been extensively studied. Here we describe the protocol for the MOONLIGHT (post-Marketed effectiveness of belimumab cOhOrt and JapaN Lupus NatIonwide ReGistry (LUNA) coHorT) study, which will use data from a Japan postmarketing surveillance study and the Lupus Registry of Nationwide Institutions (LUNA) to evaluate the real-world effectiveness of belimumab plus ST versus ST alone in patients with a history of active LN who are not in the induction phase. Methods and analysis This multicentre, retrospective, observational study (GSK Study 214710) will enrol adults with SLE and a history of active LN, holding ≥3 years of complete follow-up data from the initiation of belimumab (no continuous treatment required). Data for patients with belimumab plus ST treatment (postmarketing registry data, belimumab cohort) will be compared with those for patients with ST only treatment (LUNA data, comparison cohort). Patients who discontinue/initiate belimumab after the start of the follow-up may be included in the comparison/belimumab cohort, respectively. The primary endpoint will be the occurrence of renal flares, for which belimumab’s effectiveness will be estimated using a marginal structural model to consider time-dependent treatment and confounding factors. Secondary endpoints will include change in corticosteroid dose, renal disease activity, extrarenal disease activity, disease severity/activity biomarkers, LN class changes, end-stage kidney disease events and hospitalisations. Ethics and dissemination This study will be conducted according to the Declaration of Helsinki and the local ethical guidelines. Findings will be submitted to peer-reviewed journals and presented at scientific meetings.

Abstract
Background Systemic lupus erythematosus (SLE) is a chronic, autoimmune disease
characterized by abnormal B-cell activation and the presence of
autoantibodies, which can result in organ damage. Lupus nephritis (LN) is
the most common severe organ manifestation of SLE and may result in impaired
kidney function. However, there is limited research on the health-related
quality of life (HRQoL) burden amongst patients with LN. The objective of
this systematic literature review was to assess the HRQoL, fatigue and
health utilities associated with LN. Methods A structured literature search (GSK Study 212980) of the MEDLINE and Embase
databases was conducted in July 2019 and updated September 2021. Relevant
international congress abstracts from 2016 to 2021 were searched, and gray
literature searches and keyword-based searches in PubMed, Google, and Google
Scholar were also conducted. Results were screened according to predefined
criteria and data on the outcomes of interest were extracted. A quantitative
analysis was conducted to supplement the narrative review, to provide
36-item Short Form survey (SF-36) estimates, and to determine variation by
prognostic factors. Results Of 1155 articles identified, 26 studies for a total of 3440 patients were
included. Patients with LN showed poorer HRQoL and more fatigue than healthy
controls/the general population, although these were similar between
patients with SLE with and without LN. HRQoL was worse in patients with LN
Class III/IV or with active disease. Fatigue was generally reported as the
most burdensome symptom and was associated with lower HRQoL and increased
treatment dissatisfaction. During induction treatment, HRQoL and fatigue
were improved with mycophenolate mofetil versus cyclophosphamide. HRQoL
improved over time with treatment amongst patients with active LN. Very
limited data were identified assigning utilities to health states for
cost-effectiveness analysis. Nine studies were considered for quantitative
analysis of baseline SF-36 scores. The analysis suggested that LN has a
significant impact across all SF-36 domains, with the lowest scores in the
general health perceptions and role-physical domains and physical component
summary. Conclusions There is a large HRQoL burden in patients with LN, in particular regarding
symptoms of fatigue. Future research should focus on investigating fatigue
severity and health utilities in LN.

Abstract
BACKGROUND AND AIMS
Lupus nephritis (LN) is the most common severe manifestation of systemic lupus erythematosus (SLE) and can lead to end-stage renal disease and death. However, there are limited data to contextualize the burden of LN in Germany, with no published studies using national claims data. This cross-sectional study aimed to estimate the annual prevalence of SLE and LN from 2011–17 using claims data from the Betriebskrankenkassen (BKK) German Sickness Fund Database.
METHOD
For each study year (2011–17), three patient populations were identified using International Classification of Diseases, Tenth Revision, German Modification (ICD-10-GM) codes: (1) Patients with SLE (≥1 SLE inpatient claim or ≥1 outpatient claim with a confirmatory claim in a separate quarter within ± 3 years); (2) Patients with LN, sensitive definition (based on the presence of SLE [as above] with ≥ 1 nephritis claim within ± 1 year from the initial SLE claim) and (3) Patients with LN, specific definition (based on the presence of SLE [as above] with ≥ 2 nephritis claims in separate quarters within ± 1 year from the initial SLE claim). For each year, the annual prevalence of SLE and LN/100 000 was estimated by dividing the number of patients identified in each population by the number of individuals insured in the database in that year. The proportion of SLE patients with LN was also estimated. To estimate the total number of patients with SLE and LN in Germany by age and sex standardization, the German statutory health insurance (SHI) system (covering 87% of the German population) was used to extrapolate from the prevalence calculated in the BKK database.
RESULTS
Approximately 5 million patients were insured in the BKK database between 2011–17; the ratio of insured males to females was ∼1:1 throughout the study period. The annual prevalence of SLE and LN/100 000 increased from 2011 (SLE, 37.68; LN sensitive, 12.79; LN specific, 9.99) to 2017 (SLE, 54.74; LN sensitive, 19.06; LN specific, 15.16) (Fig. 1). In 2017, the ratio of males to females/100 000 patients was ∼1:5.5 for the SLE cohort, 1:4.5 for the LN-sensitive cohort and 1:4.4 for the LN-specific cohort.
The proportion of SLE patients with LN remained consistent across the study period, ranging from 26.51% (specific definition) and 33.96% (sensitive definition) in 2011 to 27.69% and 34.82%, respectively, in 2017.
When extrapolating the prevalence estimates to the wider German SHI system, the estimated number of SLE patients was >41 000 in 2017, with the total LN patient population ranging from 11 515 (specific definition) to 14 483 (sensitive definition) (Fig. 2).
CONCLUSION
The prevalence of LN increased between 2011 and 2017 among patients insured in the BKK database and is estimated to impact >11 000 patients in the wider German SHI system. Limitations include an absence of renal biopsy information and the inability to distinguish patients with active nephritis from those with historical or inactive LN based on clinical parameters. Nonetheless, these data highlight the prevalence of LN among patients with SLE and the need for effective screening and disease management to improve patient outcomes. Further work to understand the treatment and economic burden of LN among patients with SLE in Germany is ongoing.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease affecting both adults and children. Belimumab is the only biologic approved for SLE, and the first in a class of drugs known as B-lymphocyte stimulator-specific inhibitors. The introduction of intravenous belimumab in 2011 was a major advance, being the first new therapy approved for SLE in over 50 years. As of April 2021, more than 7200 people with SLE have received belimumab in clinical studies, and it is approved in over 75 countries for the treatment of adults with SLE. A subcutaneous, self-injectable belimumab formulation was licensed in 2017 by both the US Food and Drug Administration (FDA) and European Medicines Agency (EMA). Belimumab was then approved for use in children in Europe, the USA and Japan in 2019, and China and Brazil in 2020. Recently, belimumab became the first FDA-approved drug for the treatment of adults with active lupus nephritis (LN), the most-common severe manifestation of SLE.Over the past 10 years, belimumab has established its position as a disease modifier in the SLE treatment paradigms. Robust evidence from randomised clinical studies and observational, real-world studies has demonstrated the tolerability and efficacy of belimumab for reducing disease activity and the risk of new, severe SLE flares. This enables patients to taper their glucocorticoid use, which limits damage accumulation. Significantly more patients with active LN met the criteria for renal responses and were at less risk of a renal-related event or death after receiving belimumab plus standard therapy, compared with standard therapy on top of mandatory steroid reduction. Ongoing clinical studies are evaluating belimumab's effectiveness in various indications beyond SLE. Post-marketing and registry studies are gathering additional data on key areas such as pregnancy outcomes after belimumab exposure and belimumab co-administration with other biologics.

Abstract
INTRODUCTION Primary Sjögren's syndrome (pSS) is an autoimmune disease that affects salivary and lachrymal glands and is associated with complex extraglandular manifestations. This study investigates the clinical and economic burden and disease course of pSS in Sweden. METHODS This retrospective cohort study utilizes data from Swedish national registries and consists of patients at least 18 years of age diagnosed in secondary care with pSS, and matched members of the Swedish general population. Healthcare resource utilization (HRU) and costs were compared. The clinical burden of pSS during follow-up was explored via year-on-year prevalence of and time-to-first extraglandular manifestation. Employment status and retirement rates were used to investigate the impact of pSS on productivity. RESULTS A total of 8884 patients with pSS and 88,233 general population comparators were included. Patients with pSS had significantly higher rates of HRU and higher healthcare costs than matched comparators, including twice as many outpatient visits. Costs were highest in year 1 post index before reducing in years 2 and 3 and stabilizing thereafter. Almost two-thirds of patients received their index diagnosis during an outpatient visit, and < 30% of diagnoses were from rheumatology departments. Overall, 41% of patients experienced a healthcare encounter that included a relevant extraglandular manifestation code during follow-up. Patients with pSS had significantly higher odds of early retirement than the general population at 5 years post index. CONCLUSIONS Patients with pSS experience a high clinical and economic disease burden in Sweden.

Abstract
OBJECTIVES To describe how patients with primary SS (pSS) and systemic organ involvement are classified and clustered in routine practice. METHODS This multinational, cross-sectional survey of real-world quantitative data was conducted across Europe and the US. Rheumatologists who treated seven or more adult patients per month with pSS and current/past systemic manifestations undertook a survey before completing a patient record form capturing demographic, clinical and treatment information for their next six eligible patients. Patients with a completed patient record form were invited to complete a patient self-completion questionnaire capturing insights into their disease and treatment. Subgroups were defined by physicians' assessment of disease severity; clusters were derived based on key clinical characteristics using latent class analysis. RESULTS Rheumatologists completed 316 physician surveys and 1879 patient record forms; 888 patients completed the patient self-completion questionnaire. pSS severity reflected organ involvement and symptomatology. Latent class analysis produced five clusters distinguished by the organ systems involved and the presence of pain and fatigue symptoms at the time of the survey. A minority of patients [n = 67 (4%)] were categorized with multiple organ involvement and the highest frequency of pain and fatigue. A total of 324 patients (17%) were categorized as 'low burden'. The remaining three clusters exhibited high frequencies of articular involvement but were distinguished by the extent of other organ system involvement. CONCLUSION Cluster analysis using a real-world cohort of patients with pSS and systemic organ involvement highlights the heterogeneous presentation of patients with pSS and confirms the importance of pain and fatigue as well as organ involvement when determining disease burden.

Abstract
Introduction The real-world effectiveness of belimumab for systemic lupus erythematosus (SLE) in six countries was evaluated in the OBSErve program. The aim of this post hoc analysis (GSK study 206351) was to pool individual patient OBSErve data to further evaluate the effectiveness of belimumab in a large sample of patients with SLE. Methods OBSErve (Argentina, Canada, Germany, Spain, Switzerland, and the USA) enrolled adults ≥ 18 years of age with SLE, who were prescribed belimumab as part of standard therapy (index: date of belimumab initiation). Endpoints (month 6 vs. index) included physician-assessed overall clinical response to belimumab in the overall population (primary) and high disease activity subgroups (secondary; patients with a SLEDAI-2K/SELENA-SLEDAI score ≥ 10 or patients with high anti-dsDNA or low complement at index); other secondary endpoints included changes in glucocorticosteroid (GCS) use and changes in disease activity. Factors associated with physician-assessed overall clinical response were also evaluated. Results In total, 830 patients were included in the overall population (mean [standard deviation (SD)] age: 41.9 [12.57] years; female: 89.3%; 60.4% from the USA). Nearly half (48.1%) of belimumab-treated patients experienced a ≥ 50% physician-assessed improvement in their overall manifestations, and 13% achieved a near normalization of their condition (equal to ≥ 80% improvement). Initiating belimumab while on high-dose (> 7.5 mg/day) GCS use was associated with ≥ 50% clinical improvement at month 6 (OR: 1.9, p = 0.003). Most (78.1%; n = 518/663) patients were able to reduce or discontinue their oral GCS dose after 6 months of belimumab, with a mean (SD) change of − 8.5 (10.74) mg/day prednisone-equivalent. The mean (SD) change from belimumab initiation in disease activity score (SLEDAI-2K/SELENA-SLEDAI) was − 5.7 (4.5; n = 344). Conclusions Belimumab improves clinical manifestations of SLE and is associated with GCS dose reductions in a real-world clinical setting, supporting the real-world effectiveness of belimumab for SLE.

Abstract
Objective The understanding of systemic lupus erythematosus (SLE) and lupus nephritis (LN) pathogenesis remains incomplete. This review assessed LN development in SLE, within-LN progression and progression to end-stage renal disease (ESRD). Methods A keyword-based literature search was conducted, and 26 publications were included. Results Overall, 7–31% of patients had LN at SLE diagnosis; 31–48% developed LN after SLE diagnosis, most within 5 years. Class IV was the most commonly found LN class and had the worst prognosis. Histological transformation occurred in 40–76% of patients, more frequently from non-proliferative rather than proliferative lesions. Cumulative 5- and 10-year ESRD incidences in patients with SLE were 3% and 4%, respectively, and 3–11% and 6–19%, respectively, in patients with SLE and LN. Conclusions Elevated serum creatinine was identified as a predictor of worsening disease state, and progression within LN classes and from SLE/LN to ESRD. This review highlights the substantial risk for developing LN and progressing to ESRD amongst patients with SLE.

Abstract
BACKGROUND Mantle cell lymphoma (MCL) is a rare and aggressive form of non-Hodgkin's lymphoma. Bortezomib is the first product to be approved for the treatment of patients with previously untreated MCL, for whom haematopoietic stem cell transplantation is unsuitable, and is used in combination with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (VR-CAP). The National Institute of Health and Care Excellence recently recommended the use of VR-CAP in the UK following a technology appraisal. We present the cost effectiveness analysis performed as part of that assessment: VR-CAP versus the current standard of care regimen of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in a UK setting. METHODS A lifetime economic model was developed with health states based upon line of treatment and progression status. Baseline patient characteristics, dosing, safety and efficacy were based on the LYM-3002 trial. As overall survival data were immature, survival was modelled by progression status, and post-progression survival was assumed equal across arms. Utilities were derived from LYM-3002 and literature, and standard UK cost sources were used. RESULTS Treatment with VR-CAP compared to R-CHOP gave an incremental quality-adjusted life year (QALY) gain of 0.81 at an additional cost of £16,212, resulting in a base case incremental cost-effectiveness ratio of £20,043. Deterministic and probabilistic sensitivity analyses showed that treatment with VR-CAP was cost effective at conventional willingness-to-pay thresholds (£20,000-£30,000 per QALY). CONCLUSIONS VR-CAP is a cost-effective option for previously untreated patients with MCL in the UK.

Abstract
OBJECTIVE This study compares the cost-effectiveness of intravitreal ranibizumab vs observation and/or laser photocoagulation for treatment of macular edema secondary to retinal vein occlusion in a UK-based model. METHODS A Markov model was constructed using transition probabilities and frequency of adverse events derived using data from the BRAVO, CRUISE, and HORIZON trials. Outcomes associated with treatments and health states were combined to predict overall health costs and outcomes for cohorts treated with each option. RESULTS In branch retinal vein occlusion, ranibizumab produced a gain of 0.518 quality-adjusted life years at an incremental cost of £8141, compared with laser photocoagulation. The incremental cost-effectiveness ratio was £15,710 per quality-adjusted life year, and the incremental cost per month free from blindness was £658. In central retinal vein occlusion, ranibizumab produced a gain of 0.539 quality-adjusted life years at an incremental cost of £9216, compared with observation only. The incremental cost-effectiveness ratio was £17,103, and the incremental cost per month free from blindness was £423. CONCLUSIONS These incremental cost-effectiveness ratios are below the £20,000-30,000 range typically accepted as a threshold for cost-effectiveness. This suggests that ranibizumab may be regarded as a cost-effective therapy for patients with macular edema secondary to retinal vein occlusion, relative to grid laser photocoagulation (for BRVO) and observation (for CRVO). Limitations include sparse data for utilities associated with the severity of visual impairment in the WSE in patients with RVO. A lack of direct comparative evidence between ranibizumab and the dexamethasone intravitreal implant for the treatment of BRVO and CRVO and the infeasibility of an indirect comparison due to significant heterogeneity in trial designs prevented the inclusion of this treatment as a comparator in the Markov model.

Abstract
Background Macular oedema secondary to retinal vein occlusion (RVO) can cause vision loss due to blockage of the central retinal vein (CRVO) or a branch retinal vein (BRVO). This systematic review assessed the efficacies of widely used treatments for macular oedema secondary to RVO and the feasibility of conducting indirect comparisons between these therapies. Methods A systematic review was undertaken in November 2010, including a literature search for trials in medical databases and relevant websites. Abstracts, conference presentations and unpublished studies were considered. Studies were data-extracted and quality assessed by two independent researchers. Outcome measures included the mean change in best corrected visual acuity (BCVA) from baseline in the study eye and/or number of patients gaining at least 10 letters from baseline to 6 months or the nearest equivalent time point. Results Fourteen unique randomized controlled trials (RCTs) were identified. Ranibizumab 0.5 mg produced greater improvements in BCVA at 6 months than sham in BRVO (mean difference 11.0 letters, 95% confidence interval [CI] 7.83, 14.17) and CRVO (mean difference 14.10 letters, 95% CI 10.51, 17.69) in two double-blind sham-controlled RCTs. Pooled data from two double-blind, sham-controlled RCTs showed that improvements in BCVA were also significantly better for dexamethasone intravitreal (IVT) implant 0.7 mg compared with sham in patients with BRVO or CRVO (mean difference 2.5 letters, 95% CI 0.7, 4.3); the difference was significant for BRVO alone, but not CRVO alone. A significantly greater proportion of patients with BRVO gained ≥15 letters with laser therapy vs. no treatment at 36 months in a large prospective RCT (odds ratio 3.16, 95% CI 1.25, 8.00), whereas no difference was observed at 9 months in a smaller study. Three studies reported no benefit for laser therapy in CRVO. No indirect comparisons with ranibizumab were feasible due to differences in study design and baseline characteristics. Conclusions Data from RCTs for ranibizumab and dexamethasone IVT demonstrate that both new agents constitute significant improvements over the previously widely accepted standard of care (laser therapy) for the treatment of BRVO and CRVO. However, head-to-head studies are needed to assess the relative efficacies of licensed therapies for RVO.

Abstract
Background/aims To evaluate the cost-effectiveness of ranibizumab as either monotherapy or combined with laser therapy, compared with laser monotherapy, in the treatment of diabetic macular oedema (DME) causing visual impairment from a UK healthcare payer perspective. Methods A Markov model simulated long-term outcomes and costs of treating DME in one eye (BCVA ≤75 letters) based on data from the RESTORE Phase III trial. Outcomes measured in quality-adjusted life-years (QALYs) were simulated for a 15-year time horizon based on 12-month follow-up from RESTORE and published long-term data. Costs included treatment, disease monitoring, visual impairment and blindness (at 2010 price levels). Results Ranibizumab monotherapy resulted in a 0.17 QALY gain at an incremental cost of £4191 relative to laser monotherapy, yielding an incremental cost-effectiveness ratio (ICER) of £24 028. Probabilistic sensitivity analysis showed a 64% probability of being cost-effective at a threshold of £30 000 per QALY. Combined ranibizumab and laser therapy resulted in a 0.13 QALY gain at an incremental cost of £4695 relative to laser monotherapy (ICER £36 106; 42% probability of ICER <£30 000). Conclusions Based on RESTORE 1-year follow-up data, ranibizumab monotherapy appears to be cost-effective relative to laser monotherapy, the current standard of care. Cost-effectiveness of combination therapy is less certain. Ongoing studies will further inform on disease progression and the need for additional ranibizumab treatment.

Abstract
OBJECTIVES Therapy for osteoporosis reduces the risk of fracture in clinical trials; real-world adherence to therapy is suboptimal and may reduce the effectiveness of intervention. The objective was to assess the fracture risk among patients nonadherent versus adherent to therapy for osteoporosis. METHODS Medline, Embase, and CINAHL were searched for English-language publications of observational studies (January 1998-February 2009). Proceedings from two recent meetings of five relevant conferences were hand searched. Prospective and retrospective observational studies of patients with osteoporosis receiving bisphosphonates, parathyroid hormone, or selective estrogen receptor modulators denosumab were included. Studies were required to consider both fracture risk and adherence (compliance and/or persistence); any definition of adherence/fracture was acceptable. Data were analyzed using pooled comparisons of the odds and hazard ratios of fracture in noncompliance versus compliance and nonpersistence versus persistence. Sensitivity analyses were conducted to determine the effect of clinical heterogeneity on the results. RESULTS Twenty-seven citations were identified, the majority of which were retrospective database analyses considering the effect of adherence to bisphosphonate therapy on fracture at any skeletal site. The absolute frequency of fracture ranged from 6% to 38% with noncompliance and from 5% to 19% with nonpersistence (104-159 weeks). Meta-analysis indicates that fracture risk increases by approximately 30% with noncompliance (odds ratio [95% confidence interval] 1.29 [1.22-1.38]; hazard ratio 1.28 [1.18-1.38]) and by 30% to 40% with nonpersistence (odds ratio 1.40 [1.29-1.52]; hazard ratio 1.32 [1.23-1.42]). CONCLUSIONS Poor medication adherence is associated with a significantly increased risk of fracture versus optimal adherence. Improving medication adherence in patients with osteoporosis may lead to a greater reduction in fracture.

Abstract
BACKGROUND Biennial faecal occult blood testing (FOBT) for individuals aged 60-69 years is the primary screening tool for colorectal cancer (CRC) in the UK NHS, despite a large number of patients undergoing an unnecessary optical colonoscopy (OC) and evidence from modelling studies to suggest that more cost-effective technologies exist. CT colonography (CTC) is an emerging CRC screening technology with the potential to prevent CRC by detecting pre-cancerous polyps and to detect cancer at an earlier stage. OBJECTIVE to assess the impact of introducing CTC into the UK NHS screening programme for CRC on key health outcomes as well as the NHS budget and healthcare resource capacity. METHODS a discrete Markov model was used to reflect the natural history of CRC and the impact of three screening scenarios (biennial FOBT with and without CTC triage of patients referred to OC, and CTC every 5 years) on a range of health outcomes, including the incidence and prevalence of CRC, in a hypothetical cohort of individuals. The yearly costs, health outcomes and healthcare resource capacity requirements were estimated over a 10-year period (2009-18). RESULTS using CTC to follow up FOBT-positive patients (scenario 2) was less costly than directing all FOBT-positive patients to OC (scenario 1); saving £776 283 over 10 years for 100 000 individuals invited for screening (year 2007 values), primarily by avoiding approximately 1700 OCs, but was estimated to require 2200 additional CT scans. Implementing a programme of 5-yearly CTC as a primary screen is expected to be more expensive than FOBT screening over the short term (driven by high screening and diagnosis costs), despite substantial savings in treatment costs for CRC over the 10-year time horizon of the model and improved health outcomes. CONCLUSIONS adding CTC into the existing NHS Bowel Cancer Screening Programme as part of a preventive screening strategy could be less costly to the NHS over the longer term when used to triage FOBT-positive patients to appropriate follow-up. Increased demand for radiology services may be compensated for by reduced demand in endoscopy units.

Abstract
OBJECTIVE Niemann-Pick disease type C (NP-C) is a rare and devastating genetic disorder characterised by a range of progressive neurological symptoms, which imposes a burden on patients, family members, the healthcare system and society overall. The objective of this study was to assess direct and indirect costs associated with NP-C in the UK. METHODS This was a non-interventional, retrospective, cross-sectional cohort study based on responses from patients and/or their carers/guardians recruited from a UK NP-C database. Resource use and direct medical, direct non-medical and indirect costs were evaluated using data collected via postal survey in October 2007, which included a Medical Resource Use questionnaire. Total annual costs per patient were estimated. RESULTS In total, 18 Medical Resource Use questionnaires (29% response rate) were received and analysed. The mean total annual cost (SD) of NP-C per patient was 39,168 pounds (50,315 pounds); 46% were direct medical costs, to which home visits and residential care contributed 68% and 15%, respectively. Direct non-medical costs accounted for 24% of the average annual cost per patient, mainly due to specialist education, and indirect costs 30%. If only direct medical costs were considered, the mean annual cost (SD) per patient was reduced to 18,012 pounds (46,536 pounds). CONCLUSIONS The direct annual per-patient cost of NP-C illness in 2007 appears moderate when compared with other rare and severely disabling diseases. However, cost estimates may be conservative, since findings are limited by a small sample size, low survey response rate and potential recall bias. As demonstrated by this study, a substantial proportion of the cost is shifted from the healthcare system to the patient, family and non-medical providers. These findings highlight the need for treatments that can slow or stop disease progression in NP-C.
