Efficacy of Structured Progressive Training Exercise on Muscle Strength of Patients With Rheumatoid Arthritis

This study aims to find out if a specific exercise program helps patients with Rheumatoid Arthritis (RA). RA is a chronic autoimmune disease that causes pain, weakness, and reduced function in the joints and muscles. While medication is common, exercise is also important for management. The study will test a program called "Progressive Resistance Training." About 118 adult patients with RA at AL-Najaf Teaching Hospital will participate. They will be divided into two groups. One group will perform specific resistance exercises for six weeks, while the other group will continue their usual care without this specific training. The researchers will measure muscle strength, cardiovascular function, and energy levels before and after the six-week program. The goal is to determine if this exercise improves muscle strength and helps patients perform daily activities more efficiently. The study hopes to show that resistance training is a safe and effective way to improve quality of life for people with RA.

Clinical Cohort Construction and Therapeutic Effect Evaluation of Integrated Traditional Chinese and Western Medicine in the Treatment of Rheumatoid Arthritis

This is a large-scale, multicenter observational study on the treatment of rheumatoid arthritis (RA) with integrated Traditional Chinese and Western medicine. The study plans to enroll at least 10,000 patients, including a minimum of 1,000 cases with difficult-to-treat RA (D2T RA) and 1,000 cases with RA-associated interstitial lung disease (RA-ILD). Through long-term follow-up, data will be collected on Traditional Chinese Medicine (TCM) syndrome characteristics, treatment plans, adverse drug reactions, and complications. Biological samples, including blood and urine, will also be collected. The research will utilize multi-omics technologies such as genomics and proteomics, combined with clinical data, to deeply explore the modern scientific connotation of the "disease-syndrome-symptom" framework in RA. The goal is to clarify the patterns and advantages of TCM syndrome differentiation and treatment. Based on these findings, a scientific and standardized efficacy evaluation system for integrated treatment will be established, and optimized treatment strategies for D2T RA and RA-ILD will be developed. The project is led by multiple national TCM clinical research centers and regional diagnostic and treatment centers, including the First Teaching Hospital of Tianjin University of TCM and Shanghai Guanghua Hospital of Integrated Traditional Chinese and Western Medicine. These institutions have mature clinical research platforms, biobanks, and databases, providing a solid foundation for the successful implementation of this study. The results of this research will provide a scientific basis for the integrated treatment of RA, promote the standardization of diagnostic and treatment protocols, and ultimately improve the overall level of RA prevention and treatment in China.

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.

Plant-Based Diet for Patients With Rheumatoid Arthritis

The goal of this clinical trial is to evaluate the effect of a plant-based diet (PBD) intervention in adults with Rheumatoid Arthritis (RA) on disease activity. The investigators hypothesize that if patients with RA follow a 100% PBD over a 16-week period it will lead to improvements in: \- Disease activity (measured by DAS28), including reduction in symptoms and overall improvements in health-related quality of life. The effects of the PBD will be compared to a habitual diet, that includes no dietary changes. Participants in the intervention group will: * Receive weekly delivery of food boxes which include plant-based food items * Receive a daily multivitamin supplement * Receive continuous dietetic guidance * Participate in a practical cooking class to get an introduction to a PBD * Participate in three online supervisions throughout the intervention period Participants in the control group will follow the same plan for the project visits at the hospital but will be restricted to continue their habitual diet. Thus, not performing any dietary changes.

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.

COVID-19 Booster and IIV Schedule in Immunocompromised Hosts

The goal of this pragmatic embedded open-label, 2 x 2 factorial phase II randomized controlled trial is to evaluate strategies to improve COVID-19 booster and influenza vaccine immunogenicity in people living with immunocompromising conditions (PLIC). The main questions it aims to answer are: 1. Is co-administration of seasonal inactivated influenza vaccine (IIV) with the most up-to-date recommended COVID-19 booster dose non-inferior in inducing a 1-month peak protective humoral response against COVID-19, compared to a strategy of sequential administration of COVID-19 booster dose followed by seasonal IIV given one month later? 2. Is the administration of the most up-to-date recommended COVID-19 booster doses at 3-month intervals superior at maintaining a longer term protective humoral immune response, compared to booster doses administered at 6-month intervals? Researchers will compare (1) COVID-19 and Influenza vaccines administered at Day 0 + COVID-19 Booster at a 3-month interval, (2) COVID-19 vaccine administered at Day 0 and Influenza vaccine administered at Day 28 + COVID-19 Booster at a 3-month interval, (3) COVID-19 and Influenza vaccines administered at Day 0 + COVID-19 Booster at a 6-month interval, and (4) COVID-19 vaccine administered at Day 0 and Influenza vaccine administered at Day 28 + COVID-19 Booster at a 6-month interval to see if median neutralization capacity of patient sera is non-inferior in the co- vs. sequential administration arms at 1-month after the initial COVID-19 booster and superior in the 3-month interval arms vs. the 6-month interval arms at 12 months after the initial COVID-19 booster. These outcomes will also be compared at 2-months for question 1 and 6-months for question 2. People living with immunocompromising conditions who take part in the trial will have blood samples drawn to verify immune response, be monitored for changes in clinical events and therapies, and complete questionnaires to verify adverse effects, quality of life and economic impact.

Oral Versus Intramuscular Steroid Use to Control Rheumatoid Arthritis Flares

People living with rheumatoid arthritis (RA) often experience flares-periods where their symptoms suddenly get worse. These flares can cause significant pain, make it harder to move and do daily activities, and lower overall quality of life. Doctors often treat flares with medications called glucocorticoids (GCs), which reduce inflammation. These medications can be taken by mouth (oral/PO) or given as a single injection into the muscle (intramuscular/IM). However, it's not clear which option works better from the patient's point of view-especially when it comes to relief of symptoms, improvements in function, and satisfaction with treatment. Most research so far has focused on how well the drugs control the disease, rather than how they impact the patient's overall experience. Research Questions: 1. Does a single GC injection work just as well as taking pills over a few weeks in improving symptoms reported by patients? 2. How do the two treatments compare in terms of symptom relief, ability to function, and patient satisfaction? 3. What do patients think and feel about using GCs to treat RA flares? What the Investigators Think: The investigators believe that a one-time GC injection is just as good as taking pills for a few weeks when it comes to managing RA flares. In fact, the injection might even be safer and preferred by patients. What the Investigators are Doing: The investigators will study 220 adults with RA who are currently having a flare (with at least 3 swollen and tender joints). These patients will be recruited from rheumatology clinics at the University of Toronto and must not have used GCs in the past month. They will be randomly assigned to receive either: A single injection (Methylprednisolone 120 mg), or Oral pills (Prednisone starting at 15 mg daily and tapering down over 3 weeks). The main thing the investigators will look at is how much better patients feel after 6 weeks, based on a questionnaire designed to measure RA flares. The investigators will also look at how well they function, how satisfied they are with the treatment, and whether they had any side effects. In addition, 20 patients (10 from each group) will be interviewed to understand their experiences and opinions about flare treatment in more detail. Why This Is Possible: The investigators have already surveyed University of Toronto rheumatologists who support the idea and provided input on study design. The investigators have also partnered with experts in research methods, national arthritis organizations, and patient groups to make sure the study is relevant and meaningful. Ethics approval has been obtained. Why It Matters: RA flares can have a major impact on people's lives. While current treatments help control inflammation, the investigators need to better understand how these treatments affect people from their own perspective. This study will shift the focus to what matters most to patients, helping doctors and patients choose the best treatment based not only on medical results but also on the patient's experience. This could lead to more effective and personalized care for people living with RA.

Kinesiophobia in Rheumatoid Arthritis: Associations With Functional Disability, Disease Activity, and Related Clinical Factors

Objectives: Impairment of physical function is a core feature of RA, particularly in patients with high disease activity where pain and inflammation directly limit movement. but, Reduced mobility in RA is not exclusively driven by inflammatory pathology. There are non-inflammatory factors, including kinesiophobia, fatigue, depression, and anxiety, may significantly contribute to functional limitation and may initiate a self-perpetuating cycle in which movement avoidance leads to physical deconditioning, muscle weakness, and progressive functional decline. The aim of this study is to examine the relationship between kinesiophobia and functional outcomes in patients with rheumatoid arthritis, and to investigate its associations with disease activity, pain, fatigue, depressive symptoms, anxiety, and sarcopenia, with a focus on factors relevant to functional assessment and rehabilitation. Patients and Methods A case - control study will be conducted on Two hundred adult patients previously diagnosed with RA according to ACR/EULAR 2010 criteria for RA and 200 apparently healthy volunteers with age and sex matching will be involved in the study. The study will be conducted in Rheumatology department, Minia university Hospital, Egypt. All patients will be subjected to history taking, clinical examination, and assessment of the following parameters: 1. Kinesiophobia: using the Arabic version of TSK-17 2. Disease activity: using DAS 28 3. pain severity using the Visual Analogue Scale (VAS) 4. Fatigue: using the Arabic version of the Fatigue Severity Scale (FSS) 5. Depression: using the Arabic version of the BDI-2 6. Anxiety: using the Arabic version of the BAI 7. sarcopenia using the Arabic version of the SARC-F questionnaire 8. Functional disability: using the Arabic version of the HAQ-DI 9. Physical activity:using IPAQ-SF

Safety and Immunogenicity of the Live Attenuated Tetravalent Butantan-Dengue Vaccine in Autoimmune Rheumatic Diseases

The goal of this clinical trial is to evaluate whether the live attenuated tetravalent Butantan-Dengue vaccine (Butantan-DV) is safe and capable of inducing an immune response in patients aged 12 to 59 years with autoimmune rheumatic diseases (ARDs) who are clinically stable and under low-grade or no immunosuppression, as well as in healthy volunteers matched by sex and age. The main questions it aims to answer are: Does the vaccine induce adequate seroconversion in patients with ARDs compared to healthy controls? What is the frequency and intensity of common adverse events after vaccination in ARDs patients? Does physical activity levels and nutritional status influence vaccine-induced immune response in patients with ARDs? Researchers will compare patients with ARDs to healthy controls to evaluate if the vaccine elicits similar immune responses and safety profiles. All participants will: * receive a single 0.5 mL dose of the Butantan-DV vaccine via subcutaneous injection; * undergo blood sample collection before and after vaccination (baseline, Day 42, and Day 400) to assess antibody and cellular responses; * attend follow-up visits on Days 7, 14, and 42 for safety monitoring and laboratory tests; * report any symptoms or adverse events using a standardized diary for 42 days; * be followed for up to one year for long-term safety and immunogenicity assessments. * wear a device for 14 consecutive days to assess current and habitual physical activity levels. * answer three non-consecutive 24-hour dietary recalls, including at least one weekend day to assess nutritional status. * collect blood samples one-year after vaccination to access immunogenicity and cellular response. Researcher will also perform subgroups analysis in: A viremia subgroup (50 patients and 50 healthy controls) will provide additional samples on Days 1, 7, 14, 28, 42, and-if viremia is detected-Day 68, to evaluate post-vaccination viremia and its duration. An immunogenicity subgroup (\~20% of participants, n=96) will undergo cellular immune response testing via flow cytometry to evaluate T-cell responses.

Effect of Mediterranean vs Paleolithic Diet on RA Activity, Sarcopenia and QOL: 12-Week RCT

This study aims to evaluate the effects of Mediterranean and Paleolithic dietary interventions on nutritional status, disease activity, fatigue, sleep, and quality of life in adults with rheumatoid arthritis (RA). Participants aged 40-60 years will be randomly assigned to follow either a Mediterranean diet, a Paleolithic diet, or continue their usual diet for 12 weeks. The study will assess anthropometric measurements, disease activity score (DAS28), laboratory biomarkers (CBC, CRP, ESR, lipid profile, fasting glucose, HbA1c), and patient-reported outcomes. The trial will determine whether these diets improve RA management and overall well-being.

HiSCs in the Treatment of Rheumatoid Arthritis

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)?

Safety and Efficacy of TollB-001 Tablets in Moderate to Severe Rheumatoid Arthritis

The goal of this study is to evaluate the safety, pharmacokinetic (PK) characteristics, and preliminary efficacy of a new oral chemical drug in : adults aged 18-70 years (male or female) with moderate to severe active rheumatoid arthritis (RA), who have had inadequate response to or intolerance of at least one conventional synthetic disease-modifying antirheumatic drug (csDMARDs) . Participants will take the assigned study drug (either tollB-001 Tablets or placebo) once daily orally for 4 weeks, follow up for 1 week.

This LTFU protocol will be open to any participant who received at least one infusion of KYV-101 in a previous Kyverna sponsored clinical trial or Investigator Initiated Trial (IIT).

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.

Correlation Between Circulating Fibroblast Activation Protein (FAP) and Fibrosis in Two Diseases (Rheumatoid Arthritis and Systemic Sclerosis)

This study aims to measure a blood protein called fibroblast activation protein (FAP), which is linked to tissue scarring and inflammation. A small blood sample will be taken from participants (RA , SSc patients and healthy people ), and the FAP level will be measured and compared with routine clinical examinations, imaging studies, and lung function tests. The purpose of this study is to improve understanding of disease activity and lung involvement in these conditions and to explore whether FAP could be useful as a blood marker for future patients. Participation in this study will not change the participant's usual medical care.
