Trial Outcomes & Findings for Dose Finding Study of Namilumab in Combination With Methotrexate in Participants With Moderate to Severe Rheumatoid Arthritis (RA) (NCT NCT02379091)

NCT ID: NCT02379091

Last Updated: 2018-09-14

Results Overview

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.

Participant Flow

Participants took part in the study at 28 investigative sites in Bulgaria, Czech Republic, Japan, Poland, Russian Federation, Spain and the United Kingdom from 17 December 2014 to 05 December 2016.

Participants with a diagnosis of moderate to severe Rheumatoid Arthritis were enrolled equally in one of 4 treatment groups: placebo or 20, 80, 150 mg/mL namilumab.

Measure
Placebo
Namilumab placebo-matching, SC injection, once on Days 1, 15, 43, 71 and every 4 weeks for 12 weeks. Participants were assessed for response (a 20% improvement from Baseline in both swollen and tender joint counts). If the participant was a responder, the current treatment continued every 4 weeks up to Week 24. 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.
Namilumab 20 mg/mL
Namilumab 20 mg/mL, subcutaneous (SC) injection, once on Days 1, 15, 43, 71 and every 4 weeks for 12 Weeks. Participants were assessed for response (a 20% improvement from Baseline in both swollen and tender joint counts). If the participant was a responder, the current treatment continued every 4 weeks up to Week 24. 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.
Namilumab 80 mg/mL
Namilumab 80 mg/mL, SC injection, once on Days 1, 15, 43, 71 and every 4 weeks for 12 Weeks. Participants were assessed for response (a 20% improvement from Baseline in both swollen and tender joint counts). If the participant was a responder, the current treatment continued every 4 weeks up to Week 24. 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.
Namilumab 150 mg/mL
Namilumab 150 mg/mL, SC injection, once on Days 1, 15, 43, 71 and every 4 weeks for 12 Weeks. Participants were assessed for response (a 20% improvement from Baseline in both swollen and tender joint counts). If the participant was a responder, the current treatment continued every 4 weeks up to Week 24. If the participant was a non-responder, the participant was discontinued from the study. 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

Timeframe: Baseline and Week 12

Population: Participants from the Full Analysis Set (FAS), all participants in the safety analysis set who had at least 1 valid post-baseline assessment of DAS28-CRP in double-blind period up to Week 12, with data available at Baseline and Week 12 for analysis.

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.

SECONDARY outcome

Timeframe: Baseline and Weeks 12 and 24

Population: FAS includes all participants in the safety analysis set who had at least 1 valid post-baseline assessment of DAS28-CRP in the double-blind period up to Week 12. Number analyzed is the number of participants with data available for analysis at the given time point.

ACR20/50/70 response is defined as a ≥20/50/70% reduction from Baseline for both total joint count-68 joints (TJC68) and swollen joint count-66 joints (SJC66), and the following: * Patient's Assessment of Pain over the previous 24 hours using a Visual Analog Scale (VAS); left end of the line 0=no pain to right end of the line 100=unbearable pain * Patient's Global Assessment of Disease Activity * Physician's Global Assessment of Disease Activity over the previous 24 hours using a VAS where left end of the line 0=no disease activity to right end of the line 100=maximum disease activity * Health Assessment Questionnaire: 20 questions, 8 components: dressing/grooming, arising, eating, walking, hygiene, reach, grip and activities, 0=without difficulty to 3=unable to do * Acute-phase reactant: C-reactive Protein (CRP).

ACRn is defined as the lowest % improvement for TJC68, SJC66 and the median of 5 ACR components. These are • Patient's Assessment of Pain over previous 24 hours using a VAS; left end of line 0=no pain to right end of line 100=unbearable pain • Patient's Global Assessment of Disease Activity • Physician's Global Assessment of Disease Activity over previous 24 hours using a VAS where left end of line 0=no disease activity to right end of line 100=maximum disease activity • Health Assessment Questionnaire: 20 questions, 8 components: dressing/grooming, arising, eating, walking, hygiene, reach, grip and activities, 0=without difficulty to 3=unable to do • Acute-phase reactant: CRP. A positive % change indicates improvement. MMRM model with main effects for study site, treatment, visit, and previously failed medication with interactions between visit and treatment and visit and previously failed medication and participant used as a random effect with an unstructured covariance structure.

Timeframe: Baseline and Weeks 2, 6 and 10

Population: FAS includes all participants in the safety analysis set who had at least 1 valid postbaseline assessment of DAS28-CRP in the double-blind period up to Week 12. Number analyzed is the number of participants with data available for analysis at the given time point.

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.
