About this study
Official title: A 24-Week Randomized, Double-Blind, Placebo-Controlled, Phase 2 Dose Finding Study to Evaluate the Efficacy and Safety of 3 Doses of Namilumab (20 mg, 80 mg and 150 mg) in Combination With Methotrexate (MTX) in Subjects With Moderate to Severe Rheumatoid Arthritis (RA)
The purpose of this study is to establish proof of concept and identify the optimal efficacious dose for namilumab in RA in patients with an inadequate response to methotrexate (MTX-IR) and in patients with an inadequate response to one tumor necrosis factor (TNF)-inhibitor (TNF-IR).
Read the detailed description
The drug being tested in this study is called namilumab. Namilumab is being tested to treat rheumatoid arthritis (RA) in people who have an inadequate response to methotrexate, and in people who have an inadequate response to tumor necrosis factor-inhibitor (TNF-IR). This study will look at improvement in disease activity in participants who take namilumab.
The study will enroll approximately 100 patients. Participants will be randomly assigned (by chance) to one of the four treatment groups-which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need):
- Namilumab 20 mg/mL subcutaneous injection
- Namilumab 80 mg/mL subcutaneous injection
- Namilumab 150 mg/mL subcutaneous injection
- Placebo (dummy inactive subcutaneous injection) - this is a medication that looks like the study drug but has no active ingredient.
All participants will receive namilumab or placebo as specified in the protocol. A stable dose of methotrexate and daily folic acid will also be required treatments.
This multi-centre trial will be conducted worldwide. The overall time to participate in this study is up to approximately 40 weeks. Participants will make multiple visits to the clinic, including a follow-up assessment up to 18 weeks after the last dose of study medication.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Disease Activity Score 28 C-Reactive Protein (DAS28-CRP) at Week 12
The DAS28-CRP score is a measure of the participant's disease activity calculated using the tender joint count (TJC) [28 joints], swollen joint count (SJC) [28 joints], general health: patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity] and acute phase response: C-Reactive Protein (CRP) for a total possible score of 0 (best) to approximately 10 (worst). Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. A negative change from Baseline indicates improvement. A mixed model repeated measures (MMRM) model with main effects for study site, treatment, visit, and previously failed medication with interactions between visit and treatment, visit and previously failed medication, and visit and baseline value as a covariate and participant as a random effect with an unstructured covariance structure was used for analysis.
Measured: Baseline and Week 12
Secondary outcomes (6)
Percentage of Participants Achieving American College of Rheumatology 20% (ACR20), 50% (ACR 50) and 70% (ACR70) Response at Weeks 12 and 24

Measured: Baseline and Week 24
Change From Baseline in DAS28-CRP at Weeks 2, 6, and 10
The DAS28-CRP score is a measure of the participant's disease activity calculated using the tender joint count (TJC) [28 joints], swollen joint count (SJC) [28 joints], general health: patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity] and acute phase response: C-Reactive Protein (CRP) for a total possible score of 0 (best) to approximately 10 (worst). Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. A negative change from Baseline indicates improvement. A MMRM model with main effects for study site, treatment, visit, and previously failed medication with interactions between visit and treatment, visit and previously failed medication, and visit and baseline value as a covariate and participant as a random effect with an unstructured covariance structure was used for analysis.

If the participant was a non-responder, the participant entered an open-label period and received namilumab 150 mg/mL, SC injection, every 4 Weeks up to Week 24. All participants were on a stable dose of methotrexate tablets (15-25 mg weekly) and folic acid (at least 5 mg/week) orally throughout the duration of the study. |

Primary outcome
Change From Baseline in Disease Activity Score 28 C-Reactive Protein (DAS28-CRP) at Week 12
Time frame: Baseline and Week 12
The DAS28-CRP score is a measure of the participant's disease activity calculated using the tender joint count (TJC) [28 joints], swollen joint count (SJC) [28 joints], general health: patient's global assessment of disease activity [visual analog scale: 0=no disease activity to 100=maximum disease activity] and acute phase response: C-Reactive Protein (CRP) for a total possible score of 0 (best) to approximately 10 (worst). Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. A negative change from Baseline indicates improvement. A mixed model repeated measures (MMRM) model with main effects for study site, treatment, visit, and previously failed medication with interactions between visit and treatment, visit and previously failed medication, and visit and baseline value as a covariate and participant as a random effect with an unstructured covariance structure was used for analysis.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Namilumab, Methotrexate and Folic/folinic acid in people with Rheumatoid Arthritis, run by Takeda at 31 sites in 8 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 18 inclusion and 34 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 14 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 31 sites in Japan, Czechia, Russia, Bulgaria, Poland and 3 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 14 Sep 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?
Change From Baseline in Disease Activity Score 28 C-Reactive Protein (DAS28-CRP) at Week 12 (time frame: Baseline and Week 12). 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 NCT02379091, 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 14 Sep 2018.
