Historically, participation in clinical trials has been highly skewed towards specific demographic groups. However, research identifying which trial attributes impact participation, in either positive or negative ways, is limited. This study invites participants to record a wide range of data on their clinical trial experience, with the goal being to identify factors which persistently limit patients' ability to participate in, or complete, a trial in which they were initially interested. This data will be analyzed through a range of demographic lenses, in hopes of discovering patterns which might improve the experience of future rheumatoid arthritis patients.
Background: Pulmonary diseases are significant contributors to morbidity and mortality in patients with rheumatoid arthritis (RA). One of the most common pulmonary manifestation in RA is interstitial lung disease (RA-ILD). Consequently, RA-ILD may be prevalent in approximately 30% and clinically evident in about 10% of RA patients. Since the median survival for patients with manifest RA-ILD is only 6.6 years, feasible methods of detecting early RA-ILD are warranted. Objectives: To determine the diagnostic accuracy of thoracic ultrasound (TUS), using a 14-zone protocol, for ILD in RA patients with respiratory symptoms by using chest high-resolution computed tomography (HRCT) as the reference standard. The secondary aim is to evaluate the diagnostic accuracy for the blood biomarkers surfactant protein-D (SP-D) and microfibrillar-associated protein 4 (MFAP4) in the detection of ILD in this group of patients. Data collection: Participants will be included after signing the informed consent; data will be collected and stored in a REDCap database. Eligibility criteria for participants and settings where data will be collected: Patients eligible for inclusion are consenting adults (≥18 years) diagnosed with RA (according to the 2010 ACR-criteria for RA) and respiratory symptoms indicating RA-ILD, based on the presence of at least one of the following symptoms: unexplained dyspnoea, unexplained cough and/or a residual pneumonia or a chest X-ray indicating interstitial abnormalities in the lung. Whether participants form a consecutive, random or convenience series: Participants form a consecutive series of up to 80 individuals in total. Description of the index test and reference standard: Patients suspected of having RA-ILD will undergo a 14 zone TUS as index test performed by a junior resident in rheumatology, who is certified by the European Respiratory Society in performing TUS assessment. The anonymised images will be stored, and scored by the junior resident and two senior rheumatologists, who have also received training in TUS, as well as a TUS and ILD experienced pulmonologist. Chest HRCT will be the gold standard, i.e. the ILD reference standard. Estimates of diagnostic accuracy and their precision: The two basic measures for quantifying the diagnostic accuracy of the TUS (index) test are the sensitivity and specificity in comparison to the chest HRCT. Statistical tests will be conducted using the McNemar test for correlated proportions.
This study is a multi-center, randomized, double-blinded, controlled trial with two parallel arms. The aim of the study is to evaluate whether Colquhounia Root Tablet combined with methotrexate (MTX) might be better than MTX alone for patients with active rheumatoid arthritis (RA).
This is a drug-drug interaction study conducted in healthy volunteers to evaluate the pharmacokinetic effect of SHR0302 on CYP3A4, CYP2C9, CYP2C9, CYP2C19, using midazolam, s-warfarin, omeprazole, and repaglinide as probe drugs.

The objective of this study is to examine the efficacy of the Compassion and Mindfulness Intervention for RA (MITIG.RA), a novel intervention combining different components of Cognitive Behavioural Therapy (CBT), compared to treatment-as-usual (TAU) in the management of Rheumatoid Arthritis (RA) associated fatigue. This is a multicentre, two-arm parallel randomized controlled trial. Patients will be screened for eligibility, willingness to participate, and will be assessed and randomized to the experimental (MITIG.RA + TAU) or control condition (TAU) using computer-randomization. MITIG.RA will be delivered by a certified psychologist and comprises eight sessions of 2 hours, followed by two booster sessions. Outcomes will be assessed via validated self-report measures and include levels of fatigue (primary outcome), perceived impact of disease, depressive symptoms, mindfulness, self-compassion, safety, and satisfaction (secondary outcomes). Assessment will take place at baseline, post-intervention, before the first and second booster session (week 12 and 20, respectively), and at 32 and 44 weeks after the interventions' beginning.
This study was a randomized, double-blind, placebo-controlled phase I clinical trial of TQH3821 in adult healthy subjects, which plans to recruit 72 healthy subjects. The main purpose was to evaluate the safety and tolerance of different doses of TQH3821 or in combination with methotrexate tablets after single and multiple administration in healthy subjects.
SYBRA is an open-label, phase 3, randomized controlled clinical trial that aims to assess the use of synovial biopsies in predicting response to biologic therapy in patients with rheumatoid arthritis that have failed disease-modifying drugs. The project has the potential to help change the current practice by offering the best treatment option. The decision to choose the best treatment for a particular patient is especially important in the context of the growing number of therapies available as a first-line option and the lack of specific biomarkers to predict response to treatment.
Rheumatoid arthritis (RA) is an autoimmune, chronic inflammatory disease and TNF-alpha has been recognized as a triggering cytokine in the induction of joints inflammation and is involved in the pathogenesis of RA. Treatment for RA aims to reduce disease activity, prevent or manage joint deterioration and lower the risk of major comorbidities such as heart disease and stroke. The strategy of targeting cytokines has significantly increased RA patient outcomes. Therefore management with biological disease-modifying antirheumatic drugs "bDMARD" (Etanercept, Infliximab, Adalimumab) should be considered, If the treatment goal is not met with the first conventional synthetic drug modifying antirheumatic drugs (csDMARD) strategy, or if there are poor prognostic factors. The multi-biomarker disease activity test could be used to help standardise individual treatment decisions, especially in patients who failed to respond well to the traditional treatment. Iraq does not currently have specific guidelines, which might pose a risk to patients' safety. More data about the choice of bDMARD is needed in terms of tracking therapeutic response, or whether TNF or other pro-inflammatory cytokines like interleukin-6 (IL-6) is the main factor for the development and severity of RA. These data are important to improve the overall status of the patient, better choice of treatment and biomarkers to detect. There is limited information on the treatment patterns of rheumatoid arthritis (RA) across Iraq including the Kurdistan Region. Therefore, the aim of this research is to evaluate the efficacy, and clinical responses of RA patients who have been treated with different anti-TNF, as well as on answering the research hypothesis, Can plasma TNF-alpha and IL-6 be used as markers of therapeutic response to TNF alpha antagonist in patients with RA?
