Brief Summary:
The objective of this multicenter, randomized, double-blind study was to evaluate the efficacy and safety of continuing versus withdrawing therapy with adalimumab 40 mg given every other week SC in maintaining remission in subjects with moderate to severe non-radiographic axial spondyloarthritis.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Axial Spondyloarthritis | Biological: adalimumab Biological: Placebo | Phase 3 |
The study duration included a 42-day Screening Period, a 28-week open-label 40 mg adalimumab every other week (eow) treatment period (Period 1), a 40-week double-blind placebo controlled eow treatment period (Period 2) with an opportunity to receive at least 12 weeks of rescue therapy with open-label adalimumab (participants that flared at Weeks 60, 64 or 68 were allowed 12 weeks of rescue therapy and final visits were at Weeks 72, 76 or 80 respectively), plus a 70-day follow-up phone call. Participants in sustained Ankylosing Spondylitis Disease Activity Score (ASDAS) inactive disease were randomized at Week 28 at a 1:1 ratio to receive either blinded adalimumab 40 mg eow or matching placebo. The length of exposure to adalimumab depended on remission or flare status and ranged from 20 (first time Ankylosing Spondylitis Disease Activity Score [ASDAS] remission was calculated) to 80 weeks of treatment.

Primary Outcome Measures :
- Number of Participants Who Did Not Experience a Flare During Period 2 by Week 68 [ Time Frame: From Week 28 through 68 ]The Ankylosing Spondylitis Disease Activity Score (ASDAS) tool is a self-administered questionnaire/objective laboratory evaluation. The questionnaire assesses disease activity, back pain, and peripheral pain/swelling on a numeric rating scale (from 0 (normal) to 10 (very severe)) and duration of morning stiffness on a numeric rating scale (from 0 to 10, with 0 being none and 10 representing a duration of ≥2 hours). The laboratory parameter is a measurement of high-sensitivity C-reactive protein (mg/L) (hs-CRP). Data from five variables (disease activity, back pain, duration of morning stiffness, peripheral pain/swelling, and hs-CRP) are combined to yield a score (0 to no defined upper limit). During Period 2 participants visited study sites at Weeks 28, 32, 36, 40, 44, 48, 52, 56, 60, 64 and 68 or if they discontinued early from the study. A flare was defined as having any 2 consecutive study visits with ASDAS ≥ 2.100.
