About this study
Official title: A Phase 2, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-group, Study Evaluating the Efficacy and Safety of Ustekinumab (STELARA®) and CNTO 1959 Administered Subcutaneously in Subjects With Active Rheumatoid Arthritis Despite Concomitant Methotrexate Therapy
The purpose of this study is to evaluate the efficacy of ustekinumab and CNTO 1959 in reducing the signs and symptoms of disease in patients with active rheumatoid arthritis (RA) despite concomitant methotrexate (MTX) therapy and to evaluate the safety of ustekinumab and CNTO 1959 in this population.
Read the detailed description
This is a randomized (patients assigned to treatment by chance), double-blind (study personnel and patients will not know what treatment is being assigned to patients), multicenter, placebo-controlled (a placebo is a treatment identical in appearance to the study agent, but containing no active ingredient), dose-ranging study. Approximately 250 patients will be randomly assigned to 1 of 5 treatment groups. The maximum length of study participation is 54 weeks, including a 6-week screening period. The end of the study will be the last follow-up visit of the last patient. Study visits and evaluations will occur, and patient safety will be monitored throughout the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With American College of Rheumatology 20 (ACR 20) Response at Week 28
The ACR 20 responders are participants with at least 20 percent (%) improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: 1) patient's assessment of arthritis pain-visual analog scale, 2) patient's global assessment of disease activity-visual analog scale, 3) physician's global assessment of disease activity-visual analog scale, 4) patient's assessment of physical function as measured by health assessment questionnaire-disability index (HAQ-Di), 5) C-reactive protein (CRP).
Measured: Week 28
Secondary outcomes (3)
Change From Baseline in Disease Activity Index Score 28 (DAS28; Using C-reactive Protein [CRP]) Score at Week 28
The DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, CRP (mG/L) and patient's global assessment (PGA) of disease activity (participant rated arthritis activity assessment with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity). DAS28 <=3.2 = low disease activity, DAS28 >3.2 to 5.1 = moderate to high disease activity.
Measured: From Baseline to Week 28
Percentage of Participants With American College of Rheumatology 20 (ACR 20) Response at Week 12
The ACR 20 responders are participants with at least 20 percent (%) improvement from Baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: 1) Patient's Assessment of Arthritis Pain-Visual Analog Scale, 2) Patient's Global Assessment of Disease Activity-Visual Analog Scale, 3) Physician's Global Assessment of Disease Activity-Visual Analog Scale, 4) Patient's Assessment of Physical Function as measured by Health Assessment Questionnaire-Disability Index (HAQ-DI), 5) C-reactive Protein (CRP).
Measured: Week 12
Change From Baseline in Health Assessment Questionnaire - Disability Index (HAQ-DI) Score at Week 28
The Health Assessment Questionnaire-Disability Index (HAQ-DI): participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty.
Measured: Baseline and Week 28

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Ustekinumab + MTX (Group 2), Ustekinumab + MTX (Group 3) and CNTO 1959 + MTX (Group 4) in people with Arthritis, Rheumatoid, run by Janssen Research & Development, LLC at 47 sites in 11 countries.
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 6 inclusion and 6 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 12 May 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 47 sites in Russia, Ukraine, Poland, Colombia, Hungary and 6 more countries. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 19 Dec 2014). 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?
Percentage of Participants With American College of Rheumatology 20 (ACR 20) Response at Week 28 (time frame: Week 28). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01645280, which also lists 1 linked publication.
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 12 May 2016.
