axial spondyloarthritis


This is a pilot study to determine if further research is warranted to assess if anti-fungal therapy is an effective adjunctive treatment for axial spondyloarthropathy


The purpose of this trial is to determine if terbinafine is an effective therapy for ankylosing spondylitis. Benefit will be determined by a reduction of the BASDAI by two or more.

The primary endpoint is the BASDAI at the completion of 16 weeks of terbinafine versus the BASDAI at the start of the trial and at the completion of the placebo. The secondary endpoint with the percent of patients whose BASDAI improves by two or more while on terbinafine (week 16) versus the percent of subjects with a similar improvement after 16 weeks of placebo.
