About this study
Official title: A Phase 3, Randomized, Double-Blind, Placebo Controlled, Multicenter, Efficacy and Safety Study of Adalimumab in Adult Chinese Subjects With Active Ankylosing Spondylitis
Study of the efficacy and safety of adalimumab compared with placebo in adult Chinese participants with ankylosing spondylitis (AS) who have had an inadequate response to or who are intolerant to one or more nonsteroidal anti-inflammatory drugs (NSAIDs)
Read the detailed description
Adults with active ankylosing spondylitis (AS) were randomized in a 2:1 ratio to receive treatment with adalimumab 40 mg every other week (eow) or matching placebo, given subcutaneously (SC), in the 12-week double-blind (DB) phase. Randomized participants received one SC injection of the appropriate DB study medication (adalimumab 40 mg or matching placebo) at Week 0 and then eow until Week 10. Participants who completed the DB phase could enter the 12-week open-label (OL) phase, during which all participants received treatment with adalimumab 40 mg eow, starting at Weeks 12 through 22. No study drug was administered or injected at the final study visit (Week 24). A follow-up visit occurred 70 days after the last dose of study drug (in DB or OL phases) to obtain information on any ongoing or new adverse events (AEs).

How long does your morning stiffness last from the time you wake up?) Responses range from "none" to "very severe" or from 0 hours to 2 or more hours for morning stiffness. The score is calculated as 0.2 (Q1 + Q2 + Q3 + Q4 + Q5/2 + Q6/2).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing adalimumab in people with Ankylosing Spondylitis, run by Abbott at 9 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Nov 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants Meeting the Assessment of Spondyloarthritis International Society (ASAS) ASAS20 Response Criteria (time frame: Week 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Dec 2011.
