About
The aim of the study is to evaluate the efficacy, safety, immunogenicity, pharmacokinetics and pharmacodynamics of a fixed dose of study drug (BCD-180) in comparison with placebo in patients with active axial spondyloarthritis (axSpA). The study will include HLA-B27+ patients with radiographic (r-axSpA) and non-radiographic (nr-axSpA) who had no response to prior therapy with non-steroidal anti-rheumatic drugs (NSAIDs), have not received biologic disease-modifying anti-rheumatic drugs (bDMARDs) or targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs), and subjects with insufficient efficacy and/or loss of efficacy on bDMARDs and/or tsDMARDs.
Full description
Subjects meeting the eligibility criteria will be randomized in 2 groups:bDMARDs and/or tsDMARD naive subjects and bDMARDs and/or tsDMARD experienced subjects will be randomized independently of each other.
bDMARDs and tsDMARD-naive subjects (naïve) will be randomized into 3 groups:
- BCD-180 (naïve);
- Placebo (naïve);
- Adalimumab.
bDMARDs and/or tsDMARD experienced subjects (exp) will be randomized into 2 groups:
- BCD-180 (exp);
- Placebo (exp).
After the primary endpoint assessment all subjects will be switched to BCD-180.
