ToFAcitinib in Early Active Axial SpondyloarThritis: a Prospective, Randomized, Double-BLind, PlAcebo-CoNtrolled MulticEntre Study
This is a phase IV, multicentre, randomized, double-blind, placebo-controlled study designed to compare the efficacy and safety of tofacitinib versus placebo (on a background of an NSAID) over 16 weeks of treatment and 4 weeks of safety follow-up in subjects with early active axSpA and inadequate response to at least one NSAID, with objective signs of inflammation.
• Clinical diagnosis of axSpA and fulfilment of the ASAS classification criteria
• Symptom (back pain) duration for ≤ 2 years, according to the definition of early axial SpA by ASAS.
• Active disease activity as defined by: BASDAI ≥4 and back pain score (BASDAI question 2) of ≥4 AND objective signs of inflammation evident by osteitis in MRI of SIJ AND/OR elevated serum CRP levels.
