Study Overview
Brief Summary
This is a multicenter, two-part, randomized, double-blind, placebo-kontrolled, 4-week study with repeated doses of AP1189. The study population will consist of newly diagnosed subjects with severe active Rheumatoid Arthritis, defined with a Clinical Disease Activity score (CDAI) > 22, who are to start up-titration with methotrexate.
Detailed Description
A multicenter, two-part, randomized, double-blind, placebo-kontrolled, 4-week study with repeated doses of AP1189. The study population will consist of newly diagnosed subjects with severe active Rheumatoid Arthritis, defined with a Clinical Disease Activity score (CDAI) > 22, who are to start up-titration with methotrexate.
The study will be conducted in two parts separated by an interim analysis.
Part 1: The subjects will be randomized in a 1:1:1 ratio into: .
- AP1189 dose 50 mg
- AP1189 dose 100 mg
- placebo

50 mg AP1189. The treatment is a 4 week treatment. Each daily dose will be administered as a suspension, i e. the powder will be added 50 ml water.
Intervention: 50 mg AP1189 (Drug)
100 mg AP1189
100 mg AP1189. The treatment is a 4 week treatment. Each daily dose will be administered as a suspension, i e. the powder will be added 50 ml water.
Intervention: AP1189 (Drug)
Placebo
Placebo. The treatment is a 4 week treatment. Each daily dose will be administered as a suspension i e. the powder will be added 50 ml water.
Intervention: Placebo (Drug)
Outcomes
Primary Outcomes
Change in Clinical Disease Activity Index (CDAI)
Time Frame: 4 weeks
The change in CDAI after 4 weeks treatment compared to baseline. CDAI is calculated as a sum of: * SJC (28): Number of Swollen 28-Joint Count (shoulders, elbows, wrists, MCPs, PIPs including thumb IP, knees); * TJC (28): Number of Tender 28-Joint Count (shoulders, elbows, wrists, MCPs, PIPs including thumb IP, knees) * PGA: Patient Global Disease Activity (patient's self-assessment of overall RA disease activity on a scale 0-100, where 100 is maximal activity) * IGA: Physician's Global Disease Activity (evaluator's assessment of the subject's overall RA disease activity on a scale 0-100, where 100 is maximal activity). The CDAI score range is from 0 - 76, whereas a score of: ≤2.8 means Remission \>2.8 and ≤10 means Low Disease Activity \>10 and ≤22 means Moderate Disease Activity \>22 means High Disease Activity For the purpose of this study, a decrease in CDAI (improvement) is reported as - xx.xx).
