Medical Device for Sustained Remission in Rheumatoid Arthritis Treated With Biological Therapy

This study aims to evaluate a new tool designed to help doctors decide whether it is safe to reduce medication in patients with rheumatoid arthritis (RA) who are in remission. Rheumatoid arthritis is a chronic inflammatory disease that affects the joints, causing pain, stiffness, and reduced mobility. Many patients receive long-term treatment with biological drugs to control the disease. When the disease is well controlled (remission), doctors may gradually reduce the medication dose. However, deciding when and in whom to reduce treatment is currently based on experience and trial-and-error. The study evaluates a predictive tool (called OPTIBIO) that uses information from blood samples, genetic data, and clinical characteristics to estimate the risk that the disease will flare up if treatment is reduced. Participants in the study will be randomly assigned to one of two groups: * In one group, the decision to reduce medication will be made by their usual doctor. * In the other group, the decision will be guided by the predictive tool. The study lasts 12 months and includes several hospital visits. During these visits, participants will: * Answer questionnaires about their health and quality of life * Have physical examinations * Provide blood samples for routine tests and additional research purposes * Possibly undergo joint ultrasound (if they consent) Some additional blood samples may be stored in authorized biobanks for future research related to rheumatoid arthritis, but only if participants explicitly agree. These samples will be coded to protect personal identity and will only be used in ethically approved research projects. Participation in the study is entirely voluntary. Participants can choose which procedures they agree to and may withdraw at any time without affecting their medical care. The study may not provide direct benefit to participants, but it could help improve future treatment decisions and the overall management of rheumatoid arthritis.

Controlling Hyperactive Immunity With Long-lived Lymphocytes

This study is a Phase 1/2, open-label clinical trial to test an experimental treatment called QEL-005 in adults with two autoimmune conditions: diffuse cutaneous systemic sclerosis (dcSSc) and difficult-to-treat rheumatoid arthritis (D2TRA). The main goals are to find out whether QEL-005 is safe, how well people tolerate it, and whether it may help reduce disease activity or improve symptoms. QEL-005 is made from a participant's own white blood cells (autologous cells). These cells are collected and then changed in a laboratory using genetic methods to create specialized immune cells called CAR-T regulatory cells that target a protein on B cells called CD19. These modified cells are then given back to the participant by intravenous (IV) infusion. To take part, eligible participants will first have a procedure called leukapheresis, where some of their white blood cells are removed from the blood. The study team will use these cells to manufacture QEL005. After QEL005 is ready, participants will receive an IV infusion of their modified cells, stay in hospital overnight for monitoring, and will then be followed closely in the clinic. Throughout the trial, participants will have regular safety checks, which may include blood tests, imaging scans, questionnaires about symptoms and daily functioning, and biopsies taken from involved tissues, to help understand how QEL005 is working in the body. Detailed follow up will be for 1 year after QEL-005 infusion, and there is long-term follow up for a total of 15 years, which is standard for cell therapies. The information from this Phase 1/2 study will help determine an appropriate dose and dosing schedule of QEL005 for future studies.

Comparison of Oral Administration of a JAK Inhibitor in Rheumatoid Arthritis

The aim of this study is to offer patients two treatment options: morning or evening administration of a JAK inhibitor prescribed within the framework of its marketing authorization, according to the EULAR response. The objective is to determine whether evening administration in our patients with rheumatoid arthritis provides greater efficacy than morning administration in our patients taking JAK inhibitors once daily.

Validation of Hemoglobin A1c in Patients With Inflammatory Arthritis Treated With Sulfasalazine

The purpose of this study is to examine whether the blood test Hemoglobin A1c (HbA1c) gives an accurate picture of blood glucose levels in patients with inflammatory arthritis who are treated with sulfasalazine. HbA1c is widely used to diagnose and monitor diabetes, but sulfasalazine can shorten red blood cell lifespan and thereby lower HbA1c values independently of actual glucose levels. This may lead to underdiagnosis of diabetes in patients who develop diabetes during sulfasalazine treatment, and to undertreatment in patients with known diabetes due to falsely reassuring HbA1c values. The study aims to answer two main questions: 1. How many patients treated with sulfasalazine have undiagnosed diabetes despite having HbA1c values below the diagnostic threshold? 2. Does HbA1c underestimate actual glucose levels when compared with continuous glucose monitoring (CGM) in patients with sulfasalazine-treated inflammatory arthritis, both in those with known diabetes and those that are not diagnosed with diabetes but have borderline HbA1c values (≥ 38 mmol/mol)?

Mobile App-Based Yoga and Meditation in Rheumatoid Arthritis

The goal of this single-blind, randomized controlled trial is to evaluate the clinical effectiveness and short-term economic impact of a mobile application-based, personalized yoga and meditation program in adult patients with Rheumatoid Arthritis (RA). The main questions it aims to answer are: Does an 8-week digital yoga and meditation intervention reduce anxiety and improve other clinical/psychological outcomes (such as depression, pulmonary function, reaction time, quality of life, and stress) compared to standard medical care? Does this digital intervention reduce short-term healthcare utilization and associated direct medical costs? Researchers will compare the Mobile App Group (receiving personalized yoga and meditation via the Meditopia app) to a Control Group (receiving usual medical care) to evaluate the effectiveness and cost-efficiency of the intervention. Participants in the experimental group will: Use a mobile application to practice 15-30 minutes of yoga and 15-30 minutes of meditation daily, at least 4 days a week over an 8-week period. Complete clinical, psychometric, and economic assessments at baseline, week 4, and week 8.

A Study of LY4213663 in Healthy Participants and Participants With Rheumatoid Arthritis

The purpose of this study is to evaluate how well LY4213663 is tolerated and what side effects may occur in healthy participants and participants with rheumatoid arthritis (RA). The study drug will be administered either subcutaneously (SC) (under the skin) or intravenously (IV) (into a vein in the arm). Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. The study will last approximately 33 weeks excluding screening.

Musculoskeletal Ultrasound for Differentiating Rheumatoid and Gouty Arthritis

Rheumatoid arthritis (RA) and gouty arthritis (GA) are two common forms of joint inflammation that can present with very similar physical symptoms, making them difficult to tell apart early in the disease process. Accurate and early differentiation is crucial because the treatment strategies and long-term management for the two conditions are substantially different. The primary purpose of this observational study is to evaluate the diagnostic performance of musculoskeletal ultrasound (MSUS) in distinguishing between RA and GA. Ultrasound is a safe, radiation-free imaging tool that can visualize joint inflammation and structural changes in real-time. This study utilizes a structured semi-quantitative scoring system (graded on a scale of 0 to 3) to systematically measure the severity of joint lining thickness (synovial hypertrophy) and active blood flow (power Doppler signal). It also checks for crystal-related deposits, such as tophi or the double contour sign, which are highly suggestive of gout. Participants aged 18 and older with suspected or confirmed RA or GA who are referred for joint assessment at Assiut University Hospitals will undergo a standard clinical evaluation, routine laboratory testing, and an ultrasound examination of specific target joints (such as the wrists, hands, knees, and ankles). By comparing the ultrasound scores and specific structural findings between the two patient groups, the study aims to establish a reliable, standardized imaging approach to help physicians make faster, more confident diagnoses and initiate the correct disease-specific therapies sooner.

At-home Ultrasound Localized Therapy for Rheumatoid Arthritis Study [At-home ULTRA Study]

The At-Home ULTRA Study will evaluate performance of the MINI system as indicated for the treatment of adults with active, moderate to severe rheumatoid arthritis who are inadequate responders or are intolerant to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), biologic DMARDs (bDMARDs), or targeted synthetic DMARDs (tsDMARDs). The non-invasive study device delivers ultrasound stimulation to the spleen to reduce inflammation. The study will enroll at least 60 participants at up to 8 sites. There will be three arms consisting of two active stimulation groups (treatment) and one non-active stimulation group (sham-control). After completing the double-blinded primary endpoint assessment period at Week 12, there will be a one-way crossover of control participants to active stimulation and an additional 12 week follow-up with all participants to evaluate long-term outcomes.

COVID-19 Booster Vaccine in Autoimmune Disease Non-Responders

This is a randomized, multi-site, adaptive, open-label clinical trial comparing the immune response to different additional doses of COVID-19 vaccine in participants with autoimmune disease requiring IS medications. All study participants will have negative serologic or suboptimal responses (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result ≤200 U/mL) or a low immune response (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result \>200 U/ml and ≤2500 U/mL) to their previous doses of COVID-19 vaccine. The study will focus on 5 autoimmune diseases in adults: * Systemic Lupus Erythematosus (SLE) * Rheumatoid Arthritis (RA) * Multiple Sclerosis (MS) * Systemic Sclerosis (SSc), and * Pemphigus. This study will focus on 4 autoimmune diseases in pediatric participants: * Systemic Lupus Erythematosus (SLE) * Juvenile Idiopathic Arthritis (JIA) * Pediatric-Onset Multiple Sclerosis (POMS) * Juvenile Dermatomyositis (JDM)

An Investigation of the Effect of Smartphone Usage Levels on Cervical Posture, Tongue Pressure, Balance, and Neck Disability in Individuals With Rheumatoid Arthritis and Ankylosing Spondylitis

The purpose of this cross-sectional and comparative study is to investigate the impact of smartphone addiction on the cervical posture, musculoskeletal system, balance, and tongue pressure in individuals diagnosed with Rheumatoid Arthritis (RA) and Ankylosing Spondylitis (AS), and to compare these findings with a healthy control group. Smartphone addiction has become a major contributing factor to postural alterations such as Text Neck Syndrome. This study aims to evaluate and compare the Craniovertebral Angle (CVA), neck extensor muscle strength, Pressure Pain Thresholds (PPT) of the neck and shoulder, Single-Leg Stance (SLS) static balance, and tongue pressure among three distinct groups. A healthy control group will be included as a reference baseline to differentiate the postural and functional deterioration caused by rheumatological diseases from the additional mechanical load imposed by smartphone dependency. To eliminate the misleading effects of acute pain, joint swelling, and severe functional limitations during flare-ups, only patients with stable disease activity (DAS28 \< 3.2 for RA and BASDAI \< 4 for AS) will be enrolled. This approach aims to examine the pure biomechanical relationship between technological dependency and cervical functions, independent of active systemic inflammation.

A Study of BEN301 Injection in theTreatment of Autoimmune Diseases

The study aims to investigate the safety, tolerability, and preliminary clinical efficacy of BEN301 Injection in patients with autoimmune diseases. In patients with autoimmune diseases, Treg cells are typically deficient or dysfunctional. CAR-Treg cell therapy represents a promising strategy for the treatment of autoimmune diseases and may be applicable to a broad spectrum of autoimmune conditions. Preclinical studies have shown that BEN301 Injection not only effectively suppresses the aberrant activation of T and B cells in SLE models, but also significantly reduces total lgG secretion and the production of SLE-specific autoantibodies, particularly anti-double-stranded DNA (dsDNA) antibodies. Moreover, no significant treatment-related toxicities were observed. Treg cell therapy has already demonstrated favorable efficacy in multiple indications, including organ transplantation and autoimmune diseases, with a well-established safety and tolerability profile. Meanwhile, CAR-Treg cell therapy has been actively explored in various autoimmune conditions; several products have shown therapeutic potential, and some patients have already benefited from treatment. These findings highlight the promising prospects of CAR-Treg cell therapy in the management of autoimmune diseases.

Study of S-4321 in Participants With an Autoimmune or Immune-mediated Disease

This is a multi-center, open-label Ph 1b basket study to assess safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, biomarker response, and preliminary efficacy of multiple doses of S-4321 in adults with autoimmune or immune-mediated disease including rheumatoid arthritis (RA), psoriatic arthritis (PsA), psoriasis (PsO), cutaneous lupus erythematosus (CLE) with or without systemic manifestations, or atopic dermatitis (AD).

Carotid Ultrasound-Based Strategy for Primary Prevention of Cardiovascular Events in Inflammatory Rheumatic Disease (PREVENER)

PREVENER is a randomized, open-label, multicenter, phase IV clinical trial designed to evaluate the efficacy and safety of a carotid ultrasound-based strategy for the primary prevention of cardiovascular events in patients with inflammatory rheumatic diseases (IRD). Patients with IRD, including rheumatoid arthritis (RA), psoriatic arthritis (PsA), axial spondyloarthritis (AxSpA), and systemic lupus erythematosus (SLE), have a 50% higher risk of cardiovascular (CV) events compared to the general population. However, conventional CV risk scores (SCORE2/OP) systematically underestimate this risk, leaving many high-risk patients without appropriate preventive treatment. Patients aged ≥50 years with IRD and low-to-moderate CV risk according to SCORE2/OP will be randomized 1:1 to either an experimental group (carotid ultrasound to detect subclinical atherosclerosis) or a control group (standard care according to ESC 2021 guidelines). Patients in the experimental group with carotid plaques will be reclassified as very high CV risk and treated with high-intensity statins (LDL target \<55 mg/dL). The primary endpoint is the incidence of major adverse cardiovascular events (MACE) over 48 months of follow-up.

A Study to Evaluate the Safety and Activity of SAR448501/DR-0201 in Patients With Autoimmune Rheumatic Diseases

This is an open-label, multi-ascending dose (MAD) phase 1 study, with dose expansion at selected doses, in adult patients with select autoimmune rheumatic diseases including systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA). The purpose of the study is to identify possible optimal dose(s) by assessing the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, and preliminary clinical response of SAR448501/DR-0201. The study duration per participant will be a minimum of approximately 13 months, including a screening period of up to 28 days, a treatment period of 71 days, and a follow-up period of 42 weeks. If necessary, participants will continue to have visits after End of Study (EOS) every 4 weeks until peripheral blood B cells return to at least 80% of either the lower limit of normal (LLN) or the participant's baseline value.

A Trial of Academic Detailing to Promote Prescribing of Biosimilars

The goal of this trial is to learn if an interactive evidence-based educational outreach visits to clinicians who prescribe biologics change prescribing of biosimilar medications. The main questions it aims to answer are: 1. Do educational outreach visits lead to a higher number of prescriptions for biosimilar versions of adalimumab? 2. Do in-person or virtual visits work better? Researchers will compare clinicians offered the educational outreach visit to those who are not offered the visit to see if there is a difference in prescribing of biosimilar versions of adalimumab instead of the original brand-name version. Participants will be offered the chance to meet with a trained clinician who will provide educational information tailored to their knowledge and attitudes on the topic. They will also be provided an educational brochure and patient educational materials.

The study will have 2 parts: Part A is a single ascending dose finding (SAD) and Part B is dose escalation by fractionated dosing.

Dietary Factors and Rheumatoid Arthritis Risk in the UK Biobank

Rheumatoid arthritis (RA) is the most common inflammatory arthritis, affecting around 1% of the UK population. It affects around 400,000 adults and is characterised by synovial inflammation, cartilage and bone damage that requires lifelong treatment and represents a significant burden for both the individual and society. Diet can affect inflammatory status and RA risk, with varying risks for men and women on specific diets. People with low to moderate consumption of alcohol may be at a lower risk of RA. Those who consume lower intakes of fruit and vegetables could be at a greater risk than those with adequate intakes. This research aims to better understand the role of diet in reducing RA risk in men and women in the United Kingdom. The research will use existing dietary and lifestyle data from the United Kingdom Biobank Study and hospital records of RA incidence.
