What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants Achieving American College of Rheumatology 20 (ACR20) Response at Week 24
American College of Rheumatology (ACR) response is a composite rating scale that includes 7 variables: tender joints count (TJC [68 joints]); Swollen joints count (SJC [66 joints]); levels of an acute phase reactant (high sensitivity C-reactive protein [hs-CRP level]); participant's assessment of pain (measured on 0 [no pain]-100 mm [worst pain] visual analog scale [VAS]); participant's global assessment of disease activity (measured on 0 [no arthritis activity]-100 mm [maximal arthritis activity] VAS); physician's global assessment of disease activity (measured on 0 [no arthritis activity]-100 mm [maximal arthritis activity] VAS); participant's assessment of physical function (measured by health assessment questionnaire disability index [HAQ-DI], with scoring range of 0 [better health] - 3 [worst health]). ACR20 response was defined as achieving at least 20% improvement in both TJC and SJC, and at least 20% improvement in at least 3 of the 5 other assessments.
Measured: Week 24
Secondary outcomes (8)
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
AE: any untoward medical occurrence in a participant during the study; the event does not necessarily have a causal relationship with the treatment. This includes any newly occurring event or previous condition that has increased in severity or frequency after informed consent form is signed. AE includes serious as well as non-serious AEs. SAE (subset of AE): medical event or condition, which falls into any of the following categories, regardless of its relationship to the study drug: death, life threatening adverse experience, In-patient hospitalization/prolongation of hospitalization, persistent/significant disability or incapacity, congenital anomaly/birth defect, important medical event. Any AEs that developed or worsened or became serious during double-blind on-treatment period, single-blind on-treatment period up to 6-week post-treatment follow-up period (up to Week 58) were considered treatment-emergent.

Primary outcome
Percentage of Participants Achieving American College of Rheumatology 20 (ACR20) Response at Week 24
Time frame: Week 24
American College of Rheumatology (ACR) response is a composite rating scale that includes 7 variables: tender joints count (TJC [68 joints]); Swollen joints count (SJC [66 joints]); levels of an acute phase reactant (high sensitivity C-reactive protein [hs-CRP level]); participant's assessment of pain (measured on 0 [no pain]-100 mm [worst pain] visual analog scale [VAS]); participant's global assessment of disease activity (measured on 0 [no arthritis activity]-100 mm [maximal arthritis activity] VAS); physician's global assessment of disease activity (measured on 0 [no arthritis activity]-100 mm [maximal arthritis activity] VAS); participant's assessment of physical function (measured by health assessment questionnaire disability index [HAQ-DI], with scoring range of 0 [better health] - 3 [worst health]). ACR20 response was defined as achieving at least 20% improvement in both TJC and SJC, and at least 20% improvement in at least 3 of the 5 other assessments.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sarilumab SAR153191 (REGN88), Methotrexate and Folic acid in people with Rheumatoid Arthritis, run by Sanofi at 96 sites in Japan.
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 4 inclusion and 4 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 30 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 96 sites in Japan. 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 30 Jan 2018). 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 Achieving American College of Rheumatology 20 (ACR20) Response at Week 24 (time frame: Week 24). 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 NCT02293902, which also lists 2 linked publications.
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 30 Jan 2018.
