Continuing Versus Withdrawing Adalimumab in Maintaining Remission in Non-Radiographic Axial Spondyloarthritis

Axial Spondyloarthritis Clinical Trial

Official title: A Multicenter, Randomized, Double-Blind, Study Comparing the Efficacy and Safety of Continuing Versus Withdrawing Adalimumab Therapy in Maintaining Remission in Subjects With Non-Radiographic Axial Spondyloarthritis

Status Completed

Clinical Trial 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.

Clinical Trial Description

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. ;
