Impact of symptom duration on the short- and long-term efficacy of bimekizumab in axial spondyloarthritis: results up to 2 years.
Trial report in Arthritis research & therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 3 registered trials, which are not on this map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundBimekizumab, a monoclonal IgG1 antibody that selectively inhibits IL-17F in addition to IL-17A, showed efficacy to 2 years in patients with axial spondyloarthritis (axSpA). In this post hoc analysis, we compare the impact of shorter versus longer symptom duration on the efficacy of bimekizumab to Week 104.
methodsEfficacy outcomes by symptom duration (≤ 2 [ASAS early axSpA definition] versus > 2 years; ≤ 5 versus > 5 years) were assessed across patients from BE MOBILE 1 and 2 (non-radiographic [NCT03928704]/radiographic axSpA [NCT03928743]) and the combined open-label extension (NCT04436640). (Relative) odds ratios and (relative) differences were calculated to compare 16-week bimekizumab versus placebo treatment effect and 104-week outcomes, and infer the significance of differences, between symptom duration subgroups. Analyses were neither powered for these comparisons nor multiplicity adjusted, and should be interpreted accordingly.
resultsImproved disease activity, physical function, fatigue, health-related quality of life and objective signs of inflammation were seen with bimekizumab versus placebo at Week 16 regardless of symptom duration. Outcomes were then sustained or improved with bimekizumab to Week 104 across all subgroups. 16-week bimekizumab versus placebo treatment effect was comparable between subgroups (e.g., ≤ 2-year versus > 2-year symptom duration relative odds ratio [95% CI] for ASDAS < 2.1 in BE MOBILE 1: 0.82 [0.22, 3.08]). Significant differences were observed for some 104-week outcomes between symptom duration subgroups across both studies (e.g., ≤ 5-year versus > 5-year symptom duration odds ratio [95% CI] for ASDAS < 2.1 in BE MOBILE 2: 1.94 [1.02, 3.68]), all favouring the shorter symptom duration subgroups.
conclusionsBimekizumab was efficacious to 2 years regardless of symptom duration, with comparable 16-week treatment effect but generally better 104-week outcomes in the shorter versus longer symptom duration subgroups.
