Filling Bone Erosions: a Longitudinal Multicentric HR-pQCT Study of 12 Months Subcutaneous Tocilizumab in Rheumatoid Arthritis Phase IV Prospective Multicentrique Study

Rheumatoid arthritis (RA) is a chronic inflammatory disease mediated by the production of several cytokines, which leads to the destruction of bone and cartilage tissue in multiple joints and to bone loss. Conventional radiographs (CR) are considered as the gold standard for diagnosis and follow up of joint changes in RA. But this method has low sensitivity to detect early erosive changes and is unable to evaluate periarticular bone loss.

High Resolution peripheral QCT (HRpQCT) enables the detection of erosions less than 0.5 mm in width or depth at metacarpo-phalangeal (MCP) joints. Using 3-D high resolution analysis of cortical bone erosions, this one is also able to evaluate the volumes of erosion and the evolution under treatments IL6 (6- interleukin) plays a major role in inflammatory process and bone damages related to RA. Tocilizumab (TCZ) is a humanized anti-IL-6R monoclonal antibody, developed and investigated in several clinical trials in RA. This biotherapy, in association with methotrexate (MTX) or given in monotherapy, is efficient in RA with inadequate response to MTX or anti-TNF b (tumor necrosis factor). TCZ reduces dramatically systemic inflammation, structural progression and improves clinical symptoms and quality of life.

Tocilizumab may help reducing bone erosions, periarticular osteopenia and systemic bone loss.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
