A Pilot Study of the Feasibility of Discontinuation of Adalimumab in Stable Rheumatoid Arthritis Patients in Clinical Remission (ADMIRE)

The purpose of this pilot study is to investigate the possibility of discontinuing adalimumab therapy in patients with rheumatoid arthritis who are in stable remission after treatment with adalimumab in combination with methotrexate.

Gedetailleerde beschrijving

Treatments with adalimumab and other tumor necrosis factor (TNF) blockers, once started as therapy for rheumatoid arthritis (RA), are usually continued indefinitely. Information concerning the possibility of discontinuing anti-TNF therapy in RA patients who are in remission is limited. This is a pilot study in one country to study the effect of adalimumab discontinuation. The objective is to assess the proportion of patients with established RA in stable remission (Disease Activity Score [DAS]28 <2.6) after treatment with adalimumab in combination with methotrexate, in whom it is possible to discontinue adalimumab and to compare the remission rates among patients on sustained therapy with adalimumab + methotrexate with remission rates among patients who discontinued adalimumab.

Rheumatoid arthritis patients in stable remission (DAS28 < 2.6) treated with adalimumab + methotrexate were randomized in a 1:1 ratio to continue with adalimumab treatment or discontinue adalimumab treatment for the following 52 weeks. Subsequently an observational extension was conducted to observe patients treated at the discretion of the investigator. The observational extension period lasted until Weeks 105 - 156 (average Week 125) and consisted of one follow-up visit. Participants randomized to discontinue adalimumab therapy will be reinstituted to adalimumab if DAS28-score increases by >1.2 units from baseline and/or is scored ≥2.6 at any visit during the study and will be followed for an additional 12 weeks.

Percentage of Participants in Remission at Week 28
Tijdsspanne: Week 28

Remission is defined as a Disease Activity Score (DAS)28 of less than 2.6. The DAS28 is a validated index of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, C-reactive protein (CRP), and general health are included in the DAS28 score. Scores on the DAS28 range from 0 to 10, with higher scores indicating higher disease activity.

In this analysis participants in the methotrexate treatment group with a DAS28 score ≥ 2.6 (and thus allocated to rescue therapy with adalimumab) prior to Week 28 were considered not to be in remission at Week 28. Also, participants who did not complete 28 weeks were considered not in remission.

Tijdsspanne: Baseline and Weeks 4, 8, 12, 20, 28, 36, 44, 52, and 104-156 (extension period visit)
Physical function was evaluated using the Health Assessment Questionnaire - Disability Index (HAQ-DI), a patient-reported questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. HAQ remission indicating normal physical function is defined by HAQ-DI < 0.5.

Change From Baseline in Radiological Modified Total Sharp Score
Tijdsspanne: Baseline, Week 52, and Weeks 104-156
The van der Heijde modified Total Sharp Score (mTSS) is a measure of the level of joint damage. X-rays of hands and feet were taken at Baseline, Week 52 and the Week 104-156 visit. Joints were scored for erosions on a scale of 0 (no damage) to 5 (complete collapse) and joint space narrowing on a scale of 0 (no damage) to 4 (ankylosis or complete dislocation). Erosion scores and narrowing scores were added to obtain the mTSS (range = 0 [normal] to 398 [maximal disease]). An increase in mTSS from Baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement.
