Serum Concentration of Adalimumab as a Predictive Factor of Clinical Outcomes in Rheumatoid Arthritis (AFORA)

France69 participantsStarted 2011-01

Plain-language summary

Adalimumab is a fully human monoclonal antibody to tumor necrosis factor-alpha (TNF-α) approved in rheumatoid arthritis (RA) refractory to disease modifying anti rheumatic drugs (DMARDs) and for the treatment of severe, active and progressive RA in adults not previously treated with methotrexate. However, almost one third of patients have no response and approximately 15% develop antibodies towards adalimumab (ATA) after a 6 month course of treatment. There is a relationship between adalimumab concentration and clinical response obtained after 6 month of treatment. Furthermore adalimumab concentration measured 3 months after initiation seems to predict the clinical response at 6 months. There is an important inter individual pharmacokinetic variability of adalimumab. Side effects may occur at the recommended dose and more than 3 months of treatment are generally required to estimate the clinical response. A therapeutic drug monitoring could help clinicians to early adjust the dose to optimize the response and to avoid dose related side effects. To date there is no definite adalimumab target concentration predictive of the clinical response to allow such a pharmacologic monitoring.

Inclusion Criteria: * RA according to the American College of Rheumatology (ACR) 1987 criteria * Treatment with Adalimumab has been chosen by the physician / patient * Treatment given in accordance to the SPC * Stable Disease modifying anti rheumatic drugs (DMARDs) and glucocorticoids 4 weeks before enrollment and during the study period. * Signed consent Exclusion Criteria: * more than one previous treatment with anti TNF-alpha * Past history of malignancy, AIDS * Pregnancy * Change in DMARDS or glucocorticoid dose 4 weeks before entering the study * Active or latent tuberculosis, other active infections * Surgery scheduled during the study period

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
