Go or no-go for treat-to-target in axial spondyloarthritis?

PURPOSE OF REVIEW: For almost a decade, treat-to-target (T2T) has been advocated as a management strategy for axial spondyloarthritis (axSpA), despite a lack of trial evidence. Recently, the first and only published T2T trial in axSpA did not meet its primary endpoint. The purpose of this review is to discuss whether we should continue with a T2T approach in axSpA and to describe some experiences with T2T in clinical practice.

RECENT FINDINGS: The trial showed no superiority of T2T compared with usual care; however, several secondary trial outcomes and the health economic analysis actually favoured T2T, and there are conceivable reasons for the negative trial results. Furthermore, several knowledge gaps related to an optimal T2T approach in axSpA were identified. In clinical practice, a T2T approach was applied to only a limited extent, possibly because of several challenges.

SUMMARY: Despite one negative trial, it is too early to abandon T2T in axSpA. Not only more evidence from clinical trials but also research on the optimal target and management of all facets of axSpA, are highly needed. For successful implementation of T2T in clinical practice, it is important that barriers and facilitators to application are identified and subsequently addressed.
