Reduced Ultrasound Counts in Rheumatoid Arthritis

Status Recruiting

Clinical Trial Summary

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by intra and peri-articular synovial inflammation. Synovitis can damage the articular cartilage, bones, joint capsule, tendons and ligaments leading to the consequential functional joint deterioration.

The main goal of RA treatment is to achieve disease remission. The treatment of RA consists of synthetic and biologic disease modifying drugs (DMARDs), being the second ones selected when low disease or remission is not achieved with the first ones. Therapeutic response monitoring in RA should be closely managed. It is classically based on clinical exploration and laboratory tests. During the last decade, the resolution improvement of musculoskeletal ultrasound (MSUS) imaging has led to the gradual incorporation of this technique in the evaluation and monitoring of patients with RA, mainly due to its better capacity to detect synovitis than clinical exploration . Ultrasound imaging is highly available, non-invasive, reproducible, affordable and well accepted by patients. Ultrasound doppler mode detects pathological synovial flow, which reflects synovial inflammation and has a demonstrated sensitivity to change in multiple longitudinal studies. Sonographic evaluation of patients with RA includes the detection of synovitis in B and Doppler mode in the joints accessible by ultrasound. There has been high variability in the literature regarding the number of joints that should be evaluated for an appropriate monitoring of the RA patients. The validity for monitoring the therapeutic response in long standing RA has been demonstrated in three reduced joint counts, including 12, 7 and 6 joints. However, in shorter evolution RA, the sensitivity to change of any of these reduced ultrasound evaluations has never been studied

Clinical Trial Description

Primary objectives

• To evaluate the sensitivity to change of the Doppler Ultrasound evaluation of 12, 7 and 6 joints counts in RA patients with more than 6 months and less than 5 years of evolution, which initiate an effective treatment for the disease according to indication (biologic DMARD in monotherapy or combined with methotrexate). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
