A phase 2a proof-of-concept, randomised, double-blind, placebo-controlled study to evaluate the safety/tolerability and efficacy of 4 subcutaneous injections of namilumab (150 mg) given over 10 weeks in subjects with moderate-to-severely active axial spondyloarthritis including those previously exposed to anti- TNF therapy (NAMASTE study).
The study will assess the effect of namilumab, a GM-CSF inhibitor, on the clinical response in subjects with axial spondyloarthritis. Subjects will receive treatment with either namilumab or placebo.
