Primary efficacy Objective: •Effect of AP1189 vs. placebo in subjects with severe active RA (CDAI > 22), undergoing up-titration with MTX, by showing a change in CDAI from severe (CDAI > 22) to moderate (CDAI ≤ 22) after 4 weeks treatment compared to baseline.

E.2.2 | Secondary objectives of the trial |
Secondary efficacy Objectives: •Proportion of subjects achieving a reduction of more than 10 (ten) swollen and/or tender joints at week 4 compared to baseline •Proportion of subjects achieving a change in CDAI score at week 4 compared to baseline o Proportion of subjects with a 5-point decrease o Proportion of subjects with a 10-point decrease o Proportion of subjects with a 15-point decrease •Proportion of subjects achieving a change in value to ≤ 3.2 as measured by DAS28 at week 4 compared to baseline •Change in subject-reported HAQ-DI at week 4 compared to baseline •Change in subject-reported fatigue using FACIT-Fatigue at week 4 compared to baseline •Proportion of subjects achieving American College of Rheumatology (ACR) response assessed by ACR20, ACR50, and ACR70

Primary Safety Endpoint: The safety of AP1189 against placebo by evaluating adverse events (AEs), serious adverse events (SAEs), and laboratory abnormalities.
Primary Efficacy Endpoint: The change in CDAI after 4 weeks of treatment compared to baseline will be evaluated by assessing the following, by treatment group: •Mean change in CDAI from baseline to week 4 •Proportion of subjects with a change in CDAI score from severe (CDAI > 22) to moderate (CDAI ≤ 22) at week 4 compared to baseline.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
