Efficacy, Safety and Immunogenicity of BI 695501 Versus Adalimumab in Patients With Active Rheumatoid Arthritis: a Randomized, Double-blind,Parallel Arm, Multiple Dose, Active Comparator Trial

The Proportion of Patients Meeting the American College of Rheumatology 20% (ACR20) Response Criteria at Week 12

时间窗: Week 12

The proportion of patients meeting the ACR20 response criteria was assessed. A patient had an ACR20 response if all of the following occurred: A ≥ 20 % improvement in the swollen joint count (66 joints), A ≥ 20 % improvement in the tender joint count (68 joints), A ≥ 20 % improvement in at least three of the following assessments: Patient's assessment of pain, Patient's global assessment of disease activity (equivalent to the General Health component of the Disease Activity Score (DAS)), Physician's global assessment of disease activity, Patient's assessment of physical function, as measured by the Health Assessment Questionnaire - Disability Index (HAQ-DI) Acute phase reactant (C-reactive protein (CRP)).The Full Analysis Set contained all enrolled patients who were randomized to trial drug and who received at least one dose of trial drug and had all efficacy measures relevant for the co-primary efficacy endpoints measured at baseline and at least once post- baseline.

The Proportion of Patients Meeting ACR20 Response Criteria at Week 24

时间窗: Week 24

ACR20 at Week 12 and Week 24 are standard outcome criteria that are widely accepted for regulatory purposes to demonstrate efficacy in treating the signs and symptoms of Rheumatoid arthritis (RA). The proportion of patients meeting the ACR20 response criteria was assessed at Week 12 and Week 24 to provide a robust comparison with US-licensed Humira® data. A patient had an ACR20 response if all of the following occurred: A ≥ 20 % improvement in the swollen joint count (66 joints), A ≥ 20 % improvement in the tender joint count (68 joints), A ≥ 20 % improvement in at least three of the following assessments: Patient's assessment of pain, Patient's global assessment of disease activity (equivalent to the General Health component of the Disease Activity Score (\[DAS\]), Physician's global assessment of disease activity, Patient's assessment of physical function, as measured by the Health Assessment Questionnaire - Disability Index (HAQ-DI) Acute phase reactant (C-reactive protein \[CRP\]).
