Active clinical trials for "Arthritis"

An open label phase 3 study

The purpose of this study is to evaluate the superiority in efficacy of abatacept compared with adalimumab, on background methotrexate, in adults with early, seropositive, and shared epitope-positive rheumatoid arthritis and an inadequate methotrexate response.

ATI-450 Plus Methotrexate (MTX) Versus Placebo Plus MTX in Patients with Moderate to Severe Active Rheumatoid Arthritis (RA) who have had an Inadequate Response to MTX Alone

The purpose of this study is to investigate how RA affect the brain structures in RA-patients and if anti-inflammatory treatment that target TNF-α or JAK OR physical training of hands has positive impact on neuropsychiatric symptoms and morphological changes in the brain caused by the disease. The goal of this research project is to improve the knowledge of morphological changes in brain developed in connection to RA and to identify clinical and serological markers to predict development of those changes and finally, to investigate if anti-rheumatic interventions counteract destructive processes in the central nervous system (CNS) and improve the patient's health with respect to functionality, pain experience and psychological well-being.

The study objectives of Period 1 are to compare the efficacy, safety, and tolerability of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo for the treatment of signs and symptoms in adults with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response or intolerance to biologic disease-modifying anti-rheumatic drug (bDMARD). The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg QD and 30 mg QD in participants who have completed Period 1.

A randomized, double-blind, placebo-controlled trial including 160 consecutive patients who have been diagnosed with both rheumatoid arthritis (RA) and low bone mass and have been treated with alendronate (ALN) for five years or more. Patients will be randomized to discontinuation or continuation of alendronate. Outcomes are measured using dual energy absorptiometry (DXA), High Resolution peripheral Quantitative Computer Tomography (HR-pQCT) and biochemical markers of bone metabolism and inflammation after 6 months, 1 and 2 years.

A Multicenter, Open-label Study to Assess the Pharmacokinetics, Safety and Efficacy of Certolizumab Pegol in Children and Adolescents With Moderately to Severely Active Polyarticular-course Juvenile Idiopathic Arthritis (JIA).

This study is a comparison of quantitative Tc 99m tilmanocept imaging with IHC analysis of CD206 expression in synovial tissue of RA subjects.

Evaluation of a new screening method for sarcopenia in rheumatoid arthritis

Background: Inflammation can play a role in diseases like heart disease and rheumatoid arthritis. PET scans can help detect inflammation. Two new drugs may create better PET images. Objective: To see if the drugs [11C]ER176 and [11C]MC1 can help image inflammation. Eligibility: People ages 18 and older with rheumatoid arthritis or idiopathic inflammatory myopathy (IIM). Healthy volunteers enrolled in protocol 01-M-0254 or 17-M-0181 are also needed. Design: Healthy participants will be screened under protocol 01-M-0254 or 17-M-0181. Participants with arthritis or IIM will have a screening visit. This will include: Medical history Physical exam Blood and urine tests Possible CT or X-ray: A machine will take pictures of the body. Healthy participants will have 1 or 2 visits. They may have urine tests. They may take the drug celecoxib by mouth. They will have a PET scan. A small amount of one or both study drugs will be injected through a catheter: A needle will guide a thin plastic tube into an arm vein. Another catheter will draw blood. They will like on a bed that slides into a machine. Their vital signs and heart activity will be measured. Participants with arthritis will have up to 2 visits after screening. They may take celecoxib and have PET scans. Participants with IIM will have up to 3 visits after screening. At 1 or 2 visits, they will take celecoxib and have PET scans. They will have 1 visit where they have an MRI: They will lie on a table that slides into a machine. The machine takes pictures of the body.
