Adalimumab plus Methotrexate for Uveitis in Juvenile Idiopathic Arthritis.

BACKGROUND: Adalimumab, a fully human anti-tumor necrosis factor α monoclonal antibody, is effective in the treatment of juvenile idiopathic arthritis (JIA). We tested the efficacy of adalimumab in the treatment of JIA-associated uveitis. METHODS: In this multicenter, double-blind, randomized, placebo-controlled trial, we assessed the efficacy and safety of adalimumab in children and adolescents 2 years of age or older who had active JIA-associated uveitis. Patients who were taking a stable dose of methotrexate were randomly assigned in a 2:1 ratio to receive either adalimumab (at a dose of 20 mg or 40 mg, according to body weight) or placebo, administered subcutaneously every 2 weeks. Patients continued the trial regimen until treatment failure or until 18 months had elapsed. They were followed for up to 2 years after randomization. The primary end point was the time to treatment failure, defined according to a multicomponent intraocular inflammation score that was based on the Standardization of Uveitis Nomenclature criteria. RESULTS: The prespecified stopping criteria were met after the enrollment of 90 of 114 patients. We observed 16 treatment failures in 60 patients (27%) in the adalimumab group versus 18 treatment failures in 30 patients (60%) in the placebo group (hazard ratio, 0.25; 95% confidence interval [CI], 0.12 to 0.49; P<0.0001 [the prespecified stopping boundary]). Adverse events were reported more frequently in patients receiving adalimumab than in those receiving placebo (10.07 events per patient-year [95% CI, 9.26 to 10.89] vs. 6.51 events per patient-year [95% CI, 5.26 to 7.77]), as were serious adverse events (0.29 events per patient-year [95% CI, 0.15 to 0.43] vs. 0.19 events per patient-year [95% CI, 0.00 to 0.40]). CONCLUSIONS: Adalimumab therapy controlled inflammation and was associated with a lower rate of treatment failure than placebo among children and adolescents with active JIA-associated uveitis who were taking a stable dose of methotrexate. Patients who received adalimumab had a much higher incidence of adverse events and serious adverse events than those who received placebo.

Cost-Effectiveness Analysis of Adalimumab for the Treatment of Uveitis Associated with Juvenile Idiopathic Arthritis.

PURPOSE: To investigate the cost effectiveness of adalimumab in combination with methotrexate, compared with methotrexate alone, for the management of uveitis associated with juvenile idiopathic arthritis (JIA). DESIGN: A cost-utility analysis based on a clinical trial and decision analytic model. PARTICIPANTS: Children and adolescents 2 to 18 years of age with persistently active uveitis associated with JIA, despite optimized methotrexate treatment for at least 12 weeks. METHODS: The SYCAMORE (Randomised controlled trial of the clinical effectiveness, SafetY and Cost effectiveness of Adalimumab in combination with MethOtRExate for the treatment of juvenile idiopathic arthritis associated uveitis) trial (identifier, ISRCTN10065623) of methotrexate (up to 25 mg weekly) with or without fortnightly administered adalimumab (20 or 40 mg, according to body weight) provided data on resource use (based on patient self-report and electronic records) and health utilities (from the Health Utilities Index questionnaire). Surgical event rates and long-term outcomes were based on data from a 10-year longitudinal cohort. A Markov model was used to extrapolate the effects of treatment based on visual impairment. MAIN OUTCOME MEASURES: Medical costs to the National Health Service in the United Kingdom, utility of defined health states, quality-adjusted life-years (QALYs), and incremental cost per QALY. RESULTS: Adalimumab in combination with methotrexate resulted in additional costs of £39 316, with a 0.30 QALY gain compared with methotrexate alone, resulting in an incremental cost-effectiveness ratio of £129 025 per QALY gained. The probability of cost effectiveness at a threshold of £30 000 per QALY was less than 1%. Based on a threshold analysis, a price reduction of 84% would be necessary for adalimumab to be cost effective. CONCLUSIONS: Adalimumab is clinically effective in uveitis associated with JIA; however, its cost effectiveness is not demonstrated compared with methotrexate alone in the United Kingdom setting.

Model-free and model-based reward prediction errors in EEG.

Learning theorists posit two reinforcement learning systems: model-free and model-based. Model-based learning incorporates knowledge about structure and contingencies in the world to assign candidate actions with an expected value. Model-free learning is ignorant of the world's structure; instead, actions hold a value based on prior reinforcement, with this value updated by expectancy violation in the form of a reward prediction error. Because they use such different learning mechanisms, it has been previously assumed that model-based and model-free learning are computationally dissociated in the brain. However, recent fMRI evidence suggests that the brain may compute reward prediction errors to both model-free and model-based estimates of value, signalling the possibility that these systems interact. Because of its poor temporal resolution, fMRI risks confounding reward prediction errors with other feedback-related neural activity. In the present study, EEG was used to show the presence of both model-based and model-free reward prediction errors and their place in a temporal sequence of events including state prediction errors and action value updates. This demonstration of model-based prediction errors questions a long-held assumption that model-free and model-based learning are dissociated in the brain.

CHronic hypERtension and L-citRulline studY (CHERRY): an Early-Phase Randomised Controlled Trial in Pregnancy.

Oral supplementation with L-citrulline, which is sequentially converted to L-arginine then nitric oxide, improves vascular biomarkers and reduces blood pressure in non-pregnant, hypertensive human cohorts and pregnant mice with a pre-eclampsia-like syndrome. This early-phase randomised feasibility trial assessed the acceptability of L-citrulline supplementation to pregnant women with chronic hypertension and its effects on maternal BP and other vascular outcomes. Pregnant women with chronic hypertension were randomised at 12-16 weeks to receive 3-g L-citrulline twice daily (n = 24) or placebo (n = 12) for 8 weeks. Pregnant women reported high acceptability of oral L-citrulline. Treatment increased maternal plasma levels of citrulline, arginine and the arginine:asymmetric dimethylarginine ratio, particularly in women reporting good compliance. L-citrulline had no effect on diastolic BP (L-citrulline: - 1.82 95% CI (- 5.86, 2.22) vs placebo: - 5.00 95% CI (- 12.76, 2.76)), uterine artery Doppler or angiogenic biomarkers. Although there was no effect on BP, retrospectively, this study was underpowered to detect BP changes < 9 mmHg, limiting the conclusions about biological effects. The increase in arginine:asymmetric dimethylarginine ratio was less than in non-pregnant populations, which likely reflects altered pharmacokinetics of pregnancy, and further pharmacokinetic assessment of L-citrulline in pregnancy is advised.Trial Registration EudraCT 2015-005792-25 (2017-12-22) and ISRCTN12695929 (2018-09-20).

Effectiveness and cost-effectiveness of a web-based cardiac rehabilitation programme for people with chronic stable angina: protocol for the ACTIVATE (Angina Controlled Trial Investigating the Value of the 'Activate your heart' Therapeutic E-intervention) randomised controlled trial.

INTRODUCTION: Chronic stable angina is common and disabling. Cardiac rehabilitation is routinely offered to people following myocardial infarction or revascularisation procedures and has the potential to help people with chronic stable angina. However, there is insufficient evidence of effectiveness and cost-effectiveness for its routine use in this patient group. The objectives of this study are to compare the effectiveness and cost-effectiveness of the 'Activate Your Heart' cardiac rehabilitation programme for people with chronic stable angina compared with usual care. METHODS AND ANALYSIS: ACTIVATE is a multicentre, parallel-group, two-arm, superiority, pragmatic randomised controlled trial, with recruitment from primary and secondary care centres in England and Wales and a target sample size of 518 (1:1 allocation; allocation sequence by minimisation programme with built-in random element). The study uses secure web-based allocation concealment. The two treatments will be optimal usual care (control) and optimal usual care plus the 'Activate Your Heart' web-based cardiac rehabilitation programme (intervention). Outcome assessment and statistical analysis will be performed blinded; participants will be unblinded. Outcomes will be measured at baseline and at 6 and 12 months' follow-up. Primary outcome will be the UK version of Seattle Angina Questionnaire (SAQ-UK), physical limitations domain at 12 months' follow-up. Secondary outcomes will be the remaining two domains of SAQ-UK, dyspnoea, anxiety and depression, health utility, self-efficacy, physical activity and the incremental shuttle walk test. All safety events will be recorded, and serious adverse events assessed to determine whether they are related to the intervention and expected. Concurrent economic evaluation will be cost-utility analysis from health service perspective. An embedded process evaluation will determine the mechanisms and processes that explain the implementation and impacts of the cardiac rehabilitation programme. ETHICS AND DISSEMINATION: North of Scotland National Health Service Research Ethics Committee approval, reference 21/NS/0115. Participants will provide written informed consent. Results will be disseminated by peer-reviewed publication. TRIAL REGISTRATION NUMBER: ISRCTN10054455.

Tocilizumab in patients with anti-TNF refractory juvenile idiopathic arthritis-associated uveitis (APTITUDE): a multicentre, single-arm, phase 2 trial.

BACKGROUND: Uveitis associated with juvenile idiopathic arthritis is a cause of major ocular morbidity. A substantial proportion of children are refractory to systemic methotrexate and TNF inhibitors. Our aim was to study the safety and efficacy of tocilizumab in children with juvenile idiopathic arthritis-associated uveitis refractory to both methotrexate and TNF inhibitors. METHODS: This multicentre, single-arm, phase 2 trial was done following a Simon's two-stage design at seven tertiary hospital sites in the UK. Patients aged 2-18 years with active juvenile idiopathic arthritis-associated uveitis were eligible. All patients had been on a stable dose of methotrexate for at least 12 weeks and had not responded to treatment with a TNF inhibitor. Patients weighing 30 kg or more were treated with 162 mg subcutaneous tocilizumab every 2 weeks for 24 weeks, and participants weighing less than 30 kg were treated with 162 mg every 3 weeks for 24 weeks. The primary outcome was treatment response defined as a two-step decrease, or decrease to zero, from baseline in the level of inflammation (anterior chamber cells) at week 12, per the standardisation of uveitis nomenclature criteria. A phase 3 trial would be justified if more than seven patients responded to treatment. An interim analysis was planned to assess whether the trial would be stopped for futility, with futility defined as two or fewer treatment responses among ten participants. Adverse events were collected up to 30 calendar days after treatment cessation. The primary analysis was done in the intention-to-treat population and the safety analysis was done in all patients who started the treatment. This trial is registered with the International Standard Randomised Controlled Trial Number registry (ISRCTN95363507) and EU Clinical Trials Register (EudraCT 2015-001323-23). FINDINGS: 22 participants were enrolled to the trial between Dec 3, 2015, and March 9, 2018, and 21 participants received treatment. One participant was found to be ineligible immediately after enrolment and was therefore withdrawn. Seven of 21 (median unbiased estimate of proportion 34% [95% CI 25-57]) responded to treatment (p=0·11). Safety results were consistent with the known safety profile of tocilizumab. INTERPRETATION: The primary endpoint was not met, and thus the results do not support a phase 3 trial of tocilizumab in patients with juvenile idiopathic arthritis-associated uveitis. Importantly, data on the use of tocilizumab in clinical practice is now captured in national registries. Despite this trial not meeting the threshold required to justify a larger phase 3 trial, several patients responded to treatment; as such, tocilzumab might still be a therapeutic option in some children with uveitis refractory to anti-TNF drugs, given the absence of other treatment options.

A group intervention to improve quality of life for people with advanced dementia living in care homes: the Namaste feasibility cluster RCT.

BACKGROUND: People with advanced dementia who live and die in nursing homes experience variable quality of life, care and dying. There is a need to identify appropriate, cost-effective interventions that facilitate high-quality end-of-life care provision. OBJECTIVES: To establish the feasibility and acceptability to staff and family of conducting a cluster randomised controlled trial of the Namaste Care intervention for people with advanced dementia in nursing homes. DESIGN: The study had three phases: (1) realist review and (2) intervention refinement to inform the design of (3) a feasibility cluster randomised controlled trial with a process evaluation and economic analysis. Clusters (nursing homes) were randomised in a 3 : 1 ratio to intervention or control (usual care). The nature of the intervention meant that blinding was not possible. SETTING: Nursing homes in England providing care for people with dementia. PARTICIPANTS: Residents with advanced dementia (assessed as having a Functional Assessment Staging Test score of 6 or 7), their informal carers and nursing home staff. INTERVENTION: Namaste Care is a complex group intervention that provides structured personalised care in a dedicated space, focusing on enhancements to the physical environment, comfort management and sensory engagement. MAIN OUTCOME MEASURES: The two contender primary outcome measures were Comfort Assessment in Dying - End of Life Care in Dementia for quality of dying (dementia) and Quality of Life in Late Stage Dementia for quality of life. The secondary outcomes were as follows: person with dementia, sleep/activity (actigraphy), neuropsychiatric symptoms, agitation and pain; informal carers, satisfaction with care at the end of life; staff members, person-centred care assessment, satisfaction with care at the end of life and readiness for change; and other data - health economic outcomes, medication/service use and intervention activity. RESULTS: Phase 1 (realist review; 86 papers) identified that a key intervention component was the activities enabling the development of moments of connection. In phase 2, refinement of the intervention enabled the production of a user-friendly 16-page A4 booklet. In phase 3, eight nursing homes were recruited. Two homes withdrew before the intervention commenced; four intervention and two control homes completed the study. Residents with advanced dementia (n = 32) were recruited in intervention (n = 18) and control (n = 14) homes. Informal carers (total, n = 12: intervention, n = 5; control, n = 7) and 97 staff from eight sites (intervention, n = 75; control, n = 22) were recruited over a 6-month period. Recruitment is feasible. Completion rates of the primary outcome questionnaires were high at baseline (100%) and at 4 weeks (96.8%). The Quality of Life in Late Stage Dementia was more responsive to change over 24 weeks. Even where economic data were missing, these could be collected in a full trial. The intervention was acceptable; the dose varied depending on the staffing and physical environment of each care home. Staff and informal carers reported changes for the person with dementia in two ways: increased social engagement and greater calm. No adverse events related to the intervention were reported. CONCLUSIONS: A subsequent definitive trial is feasible if there are amendments to the recruitment process, outcome measure choice and intervention specification. FUTURE WORK: In a full trial, consideration is needed of the appropriate outcome measure that is sensitive to different participant responses, and of clear implementation principles for this person-centred intervention in a nursing home context.

Namaste Care is a programme of respectful stimulation for nursing home residents who have advanced dementia. It is person-focused and reflects residents' individual likes and interests. It is claimed that Namaste Care improves quality of life for residents, family and staff, and quality of dying for residents, and can be provided without additional cost. This study explored how feasible it would be to conduct a large study in the future to understand the effects of Namaste Care on people with advanced dementia. Our literature review showed that Namaste Care enables people with advanced dementia to have moments of connection with others. We refined some Namaste Care resources through working with care home staff, family and volunteers to create a user-friendly booklet. Eight care homes were recruited to our 6-month trial; four homes were supported to introduce Namaste Care, two continued as usual and two withdrew. In the four intervention homes, residents with advanced dementia received Namaste Care. Staff used standard measures to assess (1) residents' responses and (2) the economic costs and benefits of Namaste Care. Researchers made observation visits. Records of activity in Namaste Care sessions were completed, and interviews were held with staff and family. Residents wore an ActiGraph (Activinsights Ltd, Kimbolton, UK) device that recorded their levels of sleep and activity. The length and frequency of Namaste Care sessions varied. Nursing homes incurred additional costs but could see ways to reduce those. All residents accepted wearing an ActiGraph device. Staff completed the data collection tools; some measures were more informative than others. Data from interviews showed that most people had positive experiences of Namaste Care. The findings support the view that Namaste Care has benefits for people with advanced dementia in nursing homes. We consider that, with some changes, this trial offers a model for a large study to show whether or not Namaste Care could be promoted more widely.

Protocol for a definitive randomised controlled trial and economic evaluation of a community-based rehabilitation programme following hip fracture: fracture in the elderly multidisciplinary rehabilitation-phase III (FEMuR III).

INTRODUCTION: Proximal femoral (hip) fracture is common, serious and costly. Rehabilitation may improve functional recovery but evidence of effectiveness and cost-effectiveness are lacking. An enhanced rehabilitation intervention was previously developed and a feasibility study tested the methods used for this randomised controlled trial (RCT). The objectives are to compare the effectiveness and cost-effectiveness of the enhanced rehabilitation programme following surgical repair of proximal femoral fracture in older people compared with usual care. METHODS AND ANALYSIS: Protocol for phase III, parallel-group, two-armed, superiority, pragmatic RCT with 1:1 allocation ratio; allocation sequence by minimisation programme with a built-in random element; secure web-based allocation concealment. The two treatments will be usual care (control) and usual care plus an enhanced rehabilitation programme (intervention). The enhanced rehabilitation will consist of a patient-held information workbook, goal setting diary and up to six additional therapy sessions. Outcome assessment and statistical analysis will be performed blind; patient and carer participants will be unblinded. Outcomes will be measured at baseline, 17 and 52 weeks' follow-up. Primary outcome at 52 weeks will be the Nottingham Extended Activities of Daily Living scale. Secondary outcomes will measure anxiety and depression, health utility, cognitive status, hip pain intensity, falls self-efficacy, fear of falling, grip strength and physical function. Carer strain, anxiety and depression will be measured in carers. All safety events will be recorded, and serious adverse events will be assessed to determine whether they are related to the intervention and expected. Concurrent economic evaluation will be a cost-utility analysis from a health service and personal social care perspective. An embedded process evaluation will determine the mechanisms and processes that explain the implementation and impacts of the enhanced rehabilitation programme. ETHICS AND DISSEMINATION: National Health Service research ethics approval reference 18/NE/0300. Results will be disseminated by peer-reviewed publication.

Adalimumab in Juvenile Idiopathic Arthritis-Associated Uveitis: 5-Year Follow-up of the Bristol Participants of the SYCAMORE Trial.

PURPOSE: To determine longer-term outcomes of participants enrolled from a single center in the SYCAMORE trial, a randomized placebo-controlled trial of adalimumab vs placebo in children with juvenile idiopathic arthritis-associated uveitis (JIA-U) uncontrolled on methotrexate. DESIGN: Retrospective interventional case series. METHODS: Medical records of all 28 SYCAMORE participants recruited at the Bristol Eye Hospital were reviewed at approximately 3-monthly intervals up to 5 years from the trial randomization date. Uveitis activity, treatment course, visual outcomes, ocular complications, and adverse events were recorded. Data are presented using summary statistics. RESULTS: Following withdrawal of the investigational medicinal product (IMP), 25 of the 28 participants were started on adalimumab for active JIA-U. Of the 12 participants in the active treatment arm of the SYCAMORE study, 11 (92%) were restarted on adalimumab after withdrawal of the IMP for active JIA-U (median time to flare 188 days [range 42-413 days). Two participants stopped adalimumab for uncontrolled JIA-U. One participant had a reduction in vision to 0.3 owing to cataract. Mean visual acuity for the remaining 27 participants was -0.04 (right eye) and -0.05 (left eye). CONCLUSIONS: Drug-induced remission of JIA-U did not persist when adalimumab was withdrawn after 1-2 years of treatment. Adalimumab was well tolerated and visual acuity outcomes were excellent.

Adalimumab in combination with methotrexate for refractory uveitis associated with juvenile idiopathic arthritis: a RCT.

BACKGROUND: Children with juvenile idiopathic arthritis (JIA) are at risk of uveitis. The role of adalimumab (Humira®; AbbVie Inc., Ludwigshafen, Germany) in the management of uveitis in children needs to be determined. OBJECTIVE: To compare the efficacy, safety and cost-effectiveness of adalimumab in combination with methotrexate (MTX) versus placebo with MTX alone, with regard to controlling disease activity in refractory uveitis associated with JIA. DESIGN: This was a randomised (applying a ratio of 2 : 1 in favour of adalimumab), double-blind, placebo-controlled, multicentre parallel-group trial with an integrated economic evaluation. A central web-based system used computer-generated tables to allocate treatments. A cost-utility analysis based on visual acuity was conducted and a 10-year extrapolation by Markov modelling was also carried out. SETTING: The setting was tertiary care centres throughout the UK. PARTICIPANTS: Patients aged 2-18 years inclusive, with persistently active JIA-associated uveitis (despite optimised MTX treatment for at least 12 weeks). INTERVENTIONS: All participants received a stable dose of MTX and either adalimumab (20 mg/0.8 ml for patients weighing < 30 kg or 40 mg/0.8 ml for patients weighing ≥ 30 kg by subcutaneous injection every 2 weeks based on body weight) or a placebo (0.8 ml as appropriate according to body weight by subcutaneous injection every 2 weeks) for up to 18 months. A follow-up appointment was arranged at 6 months. MAIN OUTCOME MEASURES: Primary outcome - time to treatment failure [multicomponent score as defined by set criteria based on the Standardisation of Uveitis Nomenclature (SUN) criteria]. Economic outcome - incremental cost per quality-adjusted life-year (QALY) gained from the perspective of the NHS in England and Personal Social Services providers. Full details of secondary outcomes are provided in the study protocol. RESULTS: A total of 90 participants were randomised (adalimumab, n = 60; placebo, n = 30). There were 14 (23%) treatment failures in the adalimumab group and 17 (57%) in the placebo group. The analysis of the data from the double-blind phase of the trial showed that the hazard risk (HR) of treatment failure was significantly reduced, by 75%, for participants in the adalimumab group (HR 0.25, 95% confidence interval 0.12 to 0.51; p < 0.0001 from log-rank test). The cost-effectiveness of adalimumab plus MTX was £129,025 per QALY gained. Adalimumab-treated participants had a much higher incidence of adverse and serious adverse events. CONCLUSIONS: Adalimumab in combination with MTX is safe and effective in the management of JIA-associated uveitis. However, the likelihood of cost-effectiveness is < 1% at the £30,000-per-QALY threshold. FUTURE WORK: A clinical trial is required to define the most effective time to stop therapy. Prognostic biomarkers of early and complete response should also be identified. TRIAL REGISTRATION: Current Controlled Trials ISRCTN10065623 and European Clinical Trials Database number 2010-021141-41. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 23, No. 15. See the NIHR Journals Library website for further project information. This trial was also funded by Arthritis Research UK (grant reference number 19612). Two strengths of adalimumab (20 mg/0.8 ml and 40 mg/0.8 ml) and a matching placebo were manufactured by AbbVie Inc. (the Marketing Authorisation holder) and supplied in bulk to the contracted distributor (Sharp Clinical Services, Crickhowell, UK) for distribution to trial centres.

Juvenile idiopathic arthritis (JIA) is one of the most common rheumatic diseases in children and young people, who are at risk of developing inflammation in an area of the eye called the uvea (called uveitis). The purpose of the study was to look at how effective the use of adalimumab in combination with methotrexate (MTX) is compared with using MTX alone to treat JIA-associated uveitis. A total of 90 children (aged 2­18 years) taking MTX with JIA-associated uveitis took part in the study. If the inflammation in a patient's eye or eyes was not getting better during the 18 months, the patient was told to stop taking the study drug. It was found that those patients who were taking placebo and MTX in the trial stopped taking the study drug sooner than those who were taking adalimumab and MTX. This means that adalimumab and MTX was better at treating uveitis than MTX alone. It was found that more patients taking adalimumab and MTX together either reduced or stopped taking topical steroids than the patients taking placebo and MTX. It was found that patients taking adalimumab and MTX together experienced more side effects than those taking placebo with MTX. However, these were expected based on what was already known about adalimumab's side effects. An economic evaluation was conducted to estimate whether or not adalimumab would represent value for money for the NHS for this condition. This included long-term effects based on information about patients' clarity of vision. The analysis showed that adalimumab may not be cost-effective, as the additional costs of treatment may not be justified by the benefits. The final results show that although adalimumab used in combination with MTX does help to treat patients with JIA and uveitis, it may not represent good value for the NHS.

Namaste Care in nursing care homes for people with advanced dementia: protocol for a feasibility randomised controlled trial.

INTRODUCTION: Many people living with advanced dementia live and die in nursing care homes. The quality of life, care and dying experienced by these people is variable. Namaste Care is a multisensory programme of care developed for people with advanced dementia. While there is emerging evidence that Namaste Care may be beneficial for people with dementia, there is a need to conduct a feasibility study to establish the optimum way of delivering this complex intervention and whether benefits can be demonstrated in end-of-life care, for individuals and service delivery. The aim of the study is to ascertain the feasibility of conducting a full trial of the Namaste Care intervention. METHODS AND ANALYSIS: A feasibility study, comprising a parallel, two-arm, multicentre cluster controlled randomised trial with embedded process and economic evaluation. Nursing care homes (total of eight) who deliver care to those with advanced dementia will be randomly allocated to intervention (delivered at nursing care home level) or control. Three participant groups will be recruited: residents with advanced dementia, informal carers of a participating resident and nursing care home staff. Data will be collected for 6 months. Feasibility objectives concern the recruitment and sampling of nursing homes, residents, informal carers and staff; the selection and timing of primary (quality of dying and quality of life) and secondary clinical outcome measures (person centredness, symptom presence, agitation, quality of life, resource use and costs and residents' activity monitored using actigraphy). Acceptability, fidelity and sustainability of the intervention will be assessed using semistructured interviews with staff and informal carers. ETHICS AND DISSEMINATION: This protocol has been approved by NHS Wales Research Ethics Committee 5 (ref: 17/WA0378). Dissemination plans include working with a public involvement panel, through a website (http://www.namastetrial.org.uk), social media, academic and practice conferences and via peer reviewed publications.

A phase II trial protocol of Tocilizumab in anti-TNF refractory patients with JIA-associated uveitis (the APTITUDE trial).

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. Children with JIA are at risk of intraocular inflammation (uveitis). In the initial stages of mild-moderate inflammation uveitis is asymptomatic. Most children with mild-moderate uveitis are managed on topical steroid drops with or without systemic methotrexate (MTX). When children with moderate-severe uveitis are refractory to MTX, monoclonal anti-tumour necrosis factor agents have been trialled, interim analysis data showed positive results. However, several children with severe recalcitrant disease or non-responsive to anti-tumour necrosis factor agents remain and are at greater risk of significant ocular complications and visual loss. Further evidence of alternative therapies is needed with evidence of a potential role of anti-interleukin-6 agents in the management of severe refractory uveitis. METHODS: The trial will be conducted following a two-stage Simon design. The trial will register at least 22 patients aged 2 to 18 years with active JIA-associated uveitis, who have taken MTX for at least 12 weeks and have failed an anti-TNF agent. It will take place in 7 centres across the UK. All participants will be treated for 6 months, with follow up of 9 months from registration. Participants will receive a stable dose of MTX and those weighing ≥30 kg will be dosed with 162 mg of Tocilizumab every 2 weeks and participants weighing < 30 kg dosed with 162 mg of Tocilizumab every 3 weeks. Primary outcome is treatment response at 12 weeks. Adverse events will be collected up to 30 calendar days following treatment cessation. DISCUSSION: This is a novel adaptive design study of subcutaneous IL-6 inhibition in anti-TNF refractory JIA associated uveitis which will be able to determine if further research should be conducted. This is the first trial to look at ophthalmology outcomes in the efficacy of Tocilizumab in uveitis.This is the first paediatric clinical trial to assess the clinical effectiveness and safety of tocilizumab with MTX in JIA associated uveitis. TRIALS REGISTRATION: The Trial is registered on the ISRCTN registry (ISRCTN95363507) on the 10/06/2015 and EU Clinical Trials Register on the 03/07/2015 (EudraCT Number: 2015-001323-23).

Assessing the feasibility of injectable growth-promoting therapy in Crohn's disease.

BACKGROUND: Despite optimal therapy, many children with Crohn's disease (CD) experience growth retardation. The objectives of the study are to assess the feasibility of a randomised control trial (RCT) of injectable forms of growth-promoting therapy and to survey the attitudes of children with CD and their parents to it. METHODS: A feasibility study was carried out to determine study arms, sample size and numbers of eligible patients. A face-to-face questionnaire surveyed willingness to consent to future participation in the RCT. Eligibility to the survey was any child under 18 (with their parent/guardian) with CD whose height standard deviation score (HtSDS) was ≤+1. Of 118 questionnaires, 94 (80%) were returned (48 by children and 46 by parents). RESULTS: The median age of the patients in the survey was 14.3 years (range 7.0 to 17.7), and 35 (73%) were male. Their median HtSDS was -1.2 (-3.01, 0.23), and it was lower than the median mid-parental HtSDS of -0.6 (-3.1, 1.4). We analysed the willingness of the children whose HtSDS <-1 to take part in the proposed RCT, being those most likely to require treatment. Overall, 18 (47%) children and 17 (46%) parents were willing. This increased to 61% of children who were slightly concerned about their height and 100% (4/4) of those very concerned. A common reason for not taking part in the RCT was fear of injections (44%); 111 children are required for randomisation into three study arms from nine centres. CONCLUSIONS: Almost half of children and parents surveyed would take part in an RCT of growth-promoting therapy. Allaying fears about injections may result in higher recruitment rates.

A randomised controlled trial of the clinical effectiveness, safety and cost-effectiveness of adalimumab in combination with methotrexate for the treatment of juvenile idiopathic arthritis associated uveitis (SYCAMORE Trial).

BACKGROUND: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. Children with JIA are at risk of inflammation of the uvea in the eye (uveitis). Overall, 20% to 25% of paediatric uveitis is associated with JIA. Major risk factors for development of uveitis in JIA are oligoarticular pattern of arthritis, an age at onset of arthritis of less than seven years of age, and antinuclear antibody positivity. In the initial stages of mild to moderate inflammation the uveitis is asymptomatic. This has led to current practice of screening all children with JIA for uveitis. Approximately 12% to 38% of patients with JIA develop uveitis in seven years following onset of arthritis. In 30% to 50% of children with JIA-associated uveitis structural complications are present at diagnosis. Furthermore about 50% to 75% of those with severe uveitis will eventually develop visual impairment secondary to ocular complications such as cataract and glaucoma. Defining the severity of inflammation and structural complications in uveitis patients is now possible following Standardised Uveitis Nomenclature (SUN) guidelines, and modified to incorporate the consensus of end point and outcome criteria into the design of randomised trials. Despite current screening and therapeutic options (pre-biologics) 10% to 15% of children with JIA-associated uveitis may develop bilateral visual impairment and certified legally blind. To date, there remains no controlled trial evidence of benefits of biologic therapy. METHODS/DESIGN: This study will randomise 154 patients aged 2 to 18 years with active JIA-associated uveitis (despite methotrexate (MTX) treatment for at least 12 weeks). All participants will be treated for 18 months, with follow up of 3 years from randomisation (continuing on MTX throughout). All participants will receive a stable dose of MTX and in addition either adalimumab (20 mg/0.8 ml for patients<30 kg or 40 mg/0.8 ml for patients weighing 30 kg or more, subcutaneous (s/c) injection every 2 weeks based on body weight), or placebo (0.8 ml as appropriate according to body weight) s/c injection every 2 weeks. DISCUSSION: This is the first randomised controlled trial that will assess the clinical effectiveness, safety and cost effectiveness of adalimumab in combination with methotrexate for the treatment of juvenile idiopathic arthritis associated uveitis.
