Design of a phase IV randomised, double-blind, placebo-controlled trial assessing the ImPact of Residual Inflammation Detected via Imaging TEchniques, Drug Levels and Patient Characteristics on the Outcome of Dose TaperIng of Adalimumab in Clinical Remission Rheumatoid ArThritis (RA) patients (PREDICTRA).

ABSTRACT: INTRODUCTION:The current American College of Rheumatology and European League Against Rheumatism treatment recommendations advise tapering biological disease-modifying antirheumatic drug (bDMARD) therapy in patients with rheumatoid arthritis (RA) who achieve stable clinical remission while receiving bDMARDs. However, not all patients maintain remission or low disease activity after tapering or discontinuation of bDMARDs. The aim of the ImPact of Residual Inflammation Detected via Imaging TEchniques, Drug Levels and Patient Characteristics on the Outcome of Dose TaperIng of Adalimumab in Clinical Remission Rheumatoid ArThritis (RA) study, or PREDICTRA, is to generate data on patient and disease characteristics that may predict the clinical course of a fixed dose-tapering regimen with the bDMARD adalimumab. METHODS AND ANALYSIS:PREDICTRA is an ongoing, multicentre, phase IV, randomised, double-blind, parallel-group study of adalimumab dose tapering controlled by withdrawal in participants with RA who achieved stable clinical remission while receiving adalimumab. The study includes a screening period, a 4-week lead-in period with open-label adalimumab 40?mg every other week and a subsequent 36-week double-blind period during which participants are randomised 5:1 to adalimumab 40?mg every 3 weeks (taper arm) or placebo (withdrawal arm). The primary explanatory efficacy variables are lead-in baseline hand and wrist MRI-detected synovitis and bone marrow oedema scores, as well as a composite of both scores; the dependent variable is the occurrence of flare up to week 40. Additional efficacy variables, safety, pharmacokinetics, biomarkers and immunogenicity will also be assessed, and an ultrasound substudy will be conducted. ETHICS AND DISSEMINATION:The study is conducted in accordance with the International Conference on Harmonisation guidelines, local laws and the ethical principles of the Declaration of Helsinki. All participants are required to sign a written informed consent statement before the start of any study procedures. TRIAL REGISTRATION NUMBER:EudraCT 2014-001114-26 and NCT02198651; Pre-results.

Project description:ObjectiveTo evaluate the efficacy and safety of 2 canakinumab monotherapy tapering regimens in order to maintain complete clinical remission in children with systemic juvenile idiopathic arthritis (JIA).MethodsThe study was designed as a 2-part phase IIIb/IV open-label, randomized trial. In the first part, patients received 4 mg/kg of canakinumab subcutaneously every 4 weeks and discontinued glucocorticoids and/or methotrexate as appropriate. Patients in whom clinical remission was achieved (inactive disease for at least 24 weeks) with canakinumab monotherapy were entered into the second part of the trial, in which they were randomized 1:1 into 1 of 2 treatment arms. In arm 1, the dose of canakinumab was reduced from 4 mg/kg to 2 mg/kg and then to 1 mg/kg, followed by discontinuation. In arm 2, the 4 mg/kg dose interval was prolonged from every 4 weeks, to every 8 weeks, and then to every 12 weeks, followed by discontinuation. In both arms, canakinumab exposure could be reduced provided systemic JIA remained in clinical remission for 24 weeks with each step. The primary objective was to assess whether >40% of randomized patients in either arm maintained clinical remission of systemic JIA for 24 weeks in the first part of the study.ResultsIn part 1 of the study, 182 patients were enrolled, with 75 of those patients randomized before entering part 2 of the trial. Among the 75 randomized patients, clinical remission was maintained for 24 weeks in 27 (71%) of 38 patients in arm 1 (2 mg/kg every 4 weeks) and 31 (84%) of 37 patients in arm 2 (4 mg/kg every 8 weeks) (P ≤ 0.0001 for arm 1 versus arm 2 among those meeting the 40% threshold). Overall, 25 (33%) of 75 patients discontinued canakinumab, and clinical remission was maintained for at least 24 weeks in all 25 of these patients. No new safety signals were identified.ConclusionReduction of canakinumab exposure may be feasible in patients who have achieved clinical remission of systemic JIA, but consistent interleukin-1 inhibition appears necessary to maintain this response.

Project description:Background:Tapering of anti-tumour necrosis factor (TNF) therapy appears feasible, safe and effective in selected patients with rheumatoid arthritis (RA). Depression is highly prevalent in RA and may impact on flare incidence through various mechanisms. This study aims to investigate if psychological states predict flare in patients' dose tapering their anti-TNF therapy. Methods:This study is a post-hoc analysis of the Optimizing TNF Tapering in RA trial, a multicentre, randomised, open-label study investigating anti-TNF tapering in RA patients with sustained low disease activity. Patient-reported outcomes (Health Assessment Questionnaire, EuroQol 5-dimension scale, Functional Assessment of Chronic Illness Therapy fatigue scale (FACIT-F), 36-Item Short Form Survey (SF-36)) were collected at baseline. The primary outcome was flare, defined as an increase in 28-joint count Disease Activity Score (DAS28) ?0.6 and ?1?swollen joint. Discrete-time survival models were used to identify patient-reported outcomes that predict flare. Results:Ninety-seven patients were randomised to taper their anti-TNF dose by either 33% or 66%. Forty-one patients flared. Higher baseline DAS28 score was associated with flare (adjusted HR 1.96 (95% CI 1.18 to 3.24), p=0.01). Disability (SF-36 physical component score), fatigue (FACIT-F) and mental health (SF-36 mental health subscale (MH)) predicted flare in unadjusted models. In multivariate analyses, only SF-36 MH remained a statistically significant predictor of flare (adjusted HR per 10 units 0.74 (95% CI 0.60 to 0.93), p=0.01). Conclusions:Baseline DAS28 and mental health status are independently associated with flare in patients who taper their anti-TNF therapy. Fatigue and function also associate with flare but the effect disappears when adjusting for confounders. Given these findings, mental health and functional status should be considered in anti-TNF tapering decisions in order to optimise the likelihood of success.

Project description:ObjectiveTo evaluate the impact of upadacitinib vs placebo and adalimumab treatment, on patient-reported outcomes (PROs) in SELECT-COMPARE in an active RA population with inadequate responses to MTX (MTX-IR).MethodsPROs in patients receiving upadacitinib (15 mg QD), placebo, or adalimumab (40 mg EOW) while on background MTX were evaluated over 48 weeks. PROs included Patient Global Assessment of Disease Activity (PtGA) and pain by visual analogue scale (VAS), the HAQ Disability Index (HAQ-DI), the 36-Item Short Form Survey (SF-36), morning (AM) stiffness duration and severity, the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), and work instability. Least squares mean (LSM) changes and proportions of patients reporting improvements ≥ minimal clinically important differences (MCIDs) and scores ≥ normative values were evaluated.ResultsUpadacitinib and adalimumab resulted in greater LSM changes from baseline vs placebo across all PROs (P < 0.05) at week 12, and pain and AM stiffness severity (P < 0.05) at week 2. More upadacitinib- vs placebo-treated (P < 0.05) and similar percentages of upadacitinib- vs adalimumab-treated patients reported improvements ≥ MCID across all PROs at week 12. Upadacitinib vs adalimumab resulted in greater LSM changes from baseline in PtGA, pain, HAQ-DI, stiffness severity, FACIT-F, and the SF-36 Physical Component Summary (PCS) (all P < 0.05) at week 12. More upadacitinib- vs adalimumab-treated patients reported scores ≥ normative values in HAQ-DI and SF-36 PCS (P < 0.05) at week 12. More upadacitinib- vs adalimumab-treated patients maintained clinically meaningful improvements in PtGA, pain, HAQ-DI, FACIT-F, and AM stiffness through 48 weeks.ConclusionIn MTX-IR patients with RA, treatment with upadacitinib resulted in statistically significant and clinically meaningful improvements in PROs equivalent to or greater than with adalimumab.Trial registrationClinicalTrials.gov, http://clinicaltrials.gov, NCT02629159.
