A Clinical Study of Tulisokibart (MK-7240) to Treat Rheumatoid Arthritis (RA) (MK-7240-014)
Researchers are looking for new ways to treat rheumatoid arthritis (RA). Methotrexate (MTX) is a standard (usual) treatment for RA. However, MTX and other current treatments may not work well to treat RA symptoms for many people. This study will help find out if a study medicine called tulisokibart can treat symptoms of active RA in people who are taking MTX. In this study, researchers will look at different doses of tulisokibart. Researchers want to learn if at least one of the study doses of tulisokibart works better than a placebo to lessen RA symptoms. A placebo looks like the study medicine but has no study medicine in it. Using a placebo helps researchers better understand the effects of the study medicine.

Application of the Personalized N-of-1 Trial Design in Patients With Rheumatoid Arthritis
The goal of this N-of-1 study is to learn about treatment for individual patients who have rheumatoid arthritis (RA,) for which many treatments are available. The treatments are different in how they work, the way they are given, side- effects, and cost. While treatment guidelines are available, finding the best treatment order of treatments is often based on physician choice. The main question this study aims to answer are: * What are the effects of different treatments on RA symptoms and condition for each individual patient * What is the effectiveness of different treatments across all patients enrolled in the N-of-1 study Participants will be enrolled and randomized to a sequence of three U.S. Food and Drug Administration (FDA) approved RA medications: 1. etanercept, 2. adalimumab, 3. upadacitinib 4. tocilizumab. Participants will be asked to complete questionnaires about their condition and quality of life fortnightly, monthly and/or quarterly (either in clinic or remotely) and report their level of pain on alternate days (remotely).

Methotrexate and Metformin in Rheumatoid Arthritis Patients
Methotrexate (MTX) is the anchor drug for patients with rheumatoid arthritis (RA). Despite its marked efficacy and acceptable side effect profile, about 1/3 of patients failed to reach RA remission. Metformin is the first-line therapy for type 2 diabetes. Its antioxidative and anti-inflammatory properties make it a good candidate for the treatment of inflammatory diseases such as rheumatoid arthritis.

Effects of Phytocannabinoids on Immune Response and Autophagy During Chronic Immune-mediated Inflammatory Diseases
Cannabis, in addition to its psychotropic properties, could have anti-inflammatory and immunomodulatory effects. Phytocannabinoids (pCBs) are a group of molecules naturally secreted by the cannabis plant. The major pCBs are cannabidiol (CBD) and Δ9-tetrahydrocannabinol Δ9 (THC). Only THC has psychotropic effects, which CBD does not have. Alongside these two main components, there is a wide variety of other molecules, such as other pCBs and terpenes which could increase the effects on immune system through synergistic interactions between these different compounds ("entourage effect").In vivo, pCBs essentially interfere with the endocannabinoid system, acting on many ubiquitous receptors, present on a significant number of different cell types. Numerous published studies show that pCBs have immunomodulatory and anti-inflammatory properties by acting on several of these receptors, whether through modulation of the immune response of different cell types, effects on cytokine networks, reduction of innate and adaptive responses and/or impact on cell survival or death (autophagy, proliferation/ apoptosis). The Immune-Mediated Inflammatory Diseases (IMIDs) affect 5 to 7% of the general population in Western countries, involve different organs (joints, skin, digestive tract) but share the same inflammatory mechanisms resulting from a dysregulation of the immune response. Our research focuses on the identification of the most effective phytochemical profile of pCBs, allowing an optimal effect on chronic inflammatory pathologies of interest among immune-mediated chronic inflammatory diseases (IMIDs). The pCB-IMIDs project is therefore part of an innovative translational project, around new therapeutic applications of medical cannabis (CannAppIMIDs). In our study, we will include 100 patients with one of IMIDs among Rheumatoid Arthritis, spondylarthritis, psoriatic arthritis, Sjogren disease and systemic lupus, at different stage and with different treatments. After patient's consent we will collect for research purposes an additional 40 ml of blood during a routine care blood test. Mononuclear and polynucleated blood cells will be exposed in vitro to different full-spectrum pCB extracts (full spectrum extract) including a CBD dominant and low THC extract (\<0.2%), 1 dominant THC extract, 1 balanced THC/CBD extract and 1 dominant CBG extract. In this cross-sectional study, our objective will be to assess the biological effects of different pCB compositions on inflammatory profiles (concentrations of pro and anti-inflammatory cytokines and chemokines) and modulations of expression profiles (autophagy, apoptosis, and cannabinoid receptor expression profile).

Design and Evaluation of an Individualized Biodrug Tapering Strategy Based on Biodrug Dosage: the MONITORA Study
Rheumatoid arthritis (RA) is the most common inflammatory joint disorder. Since twenty year and the use of synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and biological (b)DMARD, remission can be reached. When remission is obtained, the physician has no recommendations for managing a step-down, and future guidelines will be useful to assist the clinician. Recent data suggest that tapering is feasible, but with high risk of flares. Flares are less frequent when bDMARD blood concentration is high. But, the optimal adalimumab concentration to keep before a step of tapering no targeting personal is unknown.

Fucoidan in the Treatment of Active Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint destruction and autoantibody production. Scavenger receptor-A (SR-A), a pattern recognition receptor primarily expressed on myeloid-derived cells, is significantly elevated in the serum of RA patients. Genetic knockout of SR-A completely protects mice from collagen-induced arthritis (CIA). As an SR-A inhibitor, fucoidan markedly suppresses the progression of CIA in mice. Given the potential role of SR-A in RA pathogenesis, the investigators hypothesize that fucoidan may exert therapeutic effects in RA by specifically targeting human SR-A. This study aims to investigate the efficacy of fucoidan in RA treatment through a randomized, double-blind, placebo-controlled trial, providing original insights into its clinical application. The investigators plan to enroll 38 patients each in the fucoidan treatment group and the control group, with a 12-week follow-up period. Clinical manifestations, laboratory parameters, and disease activity will be systematically evaluated to assess therapeutic outcomes. The findings will provide evidence-based medical data for RA treatment strategies.

Ultrasound to Guide Treatment Decisions in Patients With Rheumatoid Arthritis According to a T2T Approach
Population Patients with a diagnosis of Rheumatoid Arthritis (RA), moderate or high clinical disease activity (CDAI\>10) despite conventional synthetic (cs)DMARD(s) or bs-ts-DMARDs therapy for ≥3 months, and a maximum of 2 swollen joints (out of 44 joints) Study design Randomised multicentre, parallel-arm clinical study Primary objective Non-inferiority of the experimental arm (i.e. clinical therapy together with ultrasound guided treatment decision) in comparison to the control arm (clinically guided decision) concerning the proportion of patients reaching low disease activity (CDAI ≤10) and a minimal clinical important improvement (MCII: improvement of ≥6 points if starting from moderate disease activity, any case starting from high disease activity and achieving low disease activity) or remission according to ACR/EULAR index-based remission criteria (CDAI ≤2.8/Boolean remission) at week 24. Intervention This is a randomised multicentre, national, parallel-arm clinical study. Patients with a diagnosis of RA, moderate or high clinical disease activity (CDAI\>10) despite conventional synthetic (cs)DMARD(s) or b-tsDMARDs therapy for ≥3 months, and a maximum of 2 swollen joints (out of 44 joints) will be included and randomized to one of the following two strategic arms: 1. Clinical decision strategy: All patients receive a new course of b-ts-DMARDs, with or without concomitant cDMARD. If a CDAI ≤10 is not achieved after 12 weeks, patients are switched to a bDMARD or tsDMARD. The decision on which b/tsDMARD to use at week 12 is at the discretion of the investigator. 2. Clinical plus ultrasound-based decision strategy. All patients in this group will be evaluated by ultrasound at 44 joints. In case of clinically-verified plus ultrasound verified inflammation, patients will receive a new b-ts-DMARD while continuing or not background csDMARD(s) therapy. If a CDAI ≤10 is not achieved after 12 weeks, patients are again evaluated by ultrasound at 44 joints. In case clinically-verified plus ultrasound-verified inflammation is present, patients are switched to a bDMARD or tsDMARD. The decision on which b/tsDMARD to use is at the discretion of the investigator. In case clinically-verified plus ultrasound-verified inflammation is absent, patients receive step-up pain therapy while background treatment will be continued. Sample size 158 patients Time plan * Total duration of the study: 72 months * Active phase for each patient: 48 weeks (24 weeks for the interventional treatment strategy and 24 weeks for follow-up visit) * Recruitment: 60 months

Chronic Pain in Rheumatoid Arthritis
The objective is to identify modifiable clinical factors and neurobiological pathways that lead to the development of chronic pain in patients with early rheumatoid arthritis. Participants will undergo quantitative sensory testing, a type of testing that involves assessing response to well-defined, quantifiable painful stimuli, at 0, 3, and 12 months. A subset of participants will also undergo magnetic resonance imaging at 0 and 12 months to assess neuroimaging markers that have previously been shown to be involved in chronic pain.

BIOTIPRA: BIOmarker-guided Treatment Decisions in Psoriatic and Rheumatoid Arthritis
TNFi drugs remain the most prescribed first-line biologics for patients with rheumatoid arthritis (RA). However, up to 40% of RA patients fail to respond to TNFi treatment. One explanation of non-response is the development of anti-drug antibodies and low drug levels. Studies have consistently shown that: 1. Serum drug levels of monoclonal antibodies (such as adalimumab, certolizumab, infliximab) and the presence of anti-drug antibodies in samples taken at 3 and 6 months correlate with subsequent response at 12 months. 2. Non-responders and those who develop anti-drug antibodies are less likely to receive concomitant methotrexate or, if they do receive it, are on lower doses than responder groups. However, it has not been proven that knowing that a patient had low drug levels or anti-drug antibodies would have improved the outcome; neither has it been shown that introducing or increasing the dose of methotrexate would reduce the formation of anti-drug antibodies, thereby improving outcome. Observational data has revealed that RA non-responders, who exhibit adequate serum drug levels and no detectable anti-drug antibodies, have lower probability of response to another agent with the same mechanism of action (MOA), and may benefit in switching to a drug with a different MOA (12). RA non-responders, who have low detectable serum trough levels and detectable anti-drug antibodies, may benefit in switching to a less immunogenic drug (13, 14). These patients may have a predisposition of developing immunogenicity against the introduced foreign protein (12). Neutralising anti-drug antibodies against the TNFi etanercept or the T-cell co-stimulation inhibitor abatacept have not been detected (10, 12, 15). Furthermore whilst the use and dose of methotrexate at initiation of TNFi, has been associated with lower levels of anti-drug antibodies in our work and others (10, 16), it is not known if increasing the MTX dose once immunogenicity has developed reduces anti-drug antibodies and leads to improved treatment response. Whilst algorithms have been proposed based on these tests (4, 17, 18), they have not been confirmed in a randomised controlled trial setting to show that the intervention (testing) is effective. Based on our preliminary work in an observational dataset, this feasibility study will allow us to design a definitive study to answer the important issue of whether pharmacological testing can be utilised as robust biomarkers to optimise future patient outcomes. The next essential step, therefore, is to prove that introducing these tests improves clinical outcome. It is very important to do so because some clinicians are already requesting that their immunology laboratories introduce such tests; yet the tests themselves are expensive and have not yet shown efficacy (19). Conducting a clinical feasibility trial is one of the essential first steps in development of a full clinical trial to undertake process evaluation and assess the proposed study design, required number of participants and ensure optimum project completion. The proposed trial is a clinical feasibility trial with the aim to ensure a realistic assessment and capability to conduct the full clinical trial. Participants with RA, commencing adalimumab or certolizumab will be randomised to determine whether providing test results on adalimumab/certolizumab drug levels and anti-drug antibodies at 4 weeks, 3 and 6 months to clinicians caring for patients with RA (n=15 patients) starting on treatment with adalimumab/certolizumab, improves the course of disease activity, compared to standard care (n=15 patients). Clinicians will be provided with feedback and a treatment algorithm. The feasibility of the study will be assessed by a number of factors including evaluation of recruitment, attrition, data completeness and process evaluation. The results will be used to inform the number of participants required to fully evaluate the intervention.

Evolution and Treatments of Chronic Inflammatory Systemic Diseases
Patients with chronic inflammatory diseases (CID) followed in gastroenterology, dermatology and rheumatology have physiopathological, epidemiological and therapeutic focal points. The pathologies concerned are inflammatory bowel diseases (IBD - Crohn's disease \[MC\] and ulcerative colitis \[RCH\]), chronic inflammatory skin diseases (psoriasis or Verneuil's disease) and chronic inflammatory rheumatic diseases (rheumatoid arthritis \[RA\] and spondyloarthritis \[SpA\] including psoriatic arthritis \[PsA\]). Presenting one of these diseases is associated with a higher risk of having a second inflammatory pathology, whether the latter is ophthalmological, dermatological, rheumatological or gastroenterological. An association of extra-articular manifestations is observed in 10 to 30% of patients with SpA, and an association of extra-intestinal manifestations is observed in approximately 30% of patients with IBD. No common database for chronic systemic inflammatory diseases currently exists in France.

Impact of a High-fiber Diet on the Microbiome and Disease Activity in Patients With Rheumatoid Arthritis
The goal of this clinical trial is to learn if increasing dietary fiber can improve the gut microbiome and reduce disease activity in adults with rheumatoid arthritis (RA). The main questions it aims to answer are: * Can a higher fiber diet improve gut bacteria and produce beneficial short-chain fatty acids (SCFAs)? * Does a higher fiber diet reduce RA symptoms and help with weight loss? Researchers will compare two groups: one group will receive dietary counseling and take 10 grams of psyllium husk daily, while the other group will continue their usual diet. Participants will: * Complete dietary questionnaires at the start, 6 months, and 12 months. * Provide stool samples for gut bacteria and SCFA analysis. * Have their RA activity and body weight monitored regularly. * Receive regular phone calls to support the dietary changes. The study will involve adults with diagnosed RA who can provide informed consent and meet other inclusion criteria.
