Time to Premature Treatment Discontinuation Due to Any Reason
Ramy czasowe: Up to the treatment discontinuation or the date of the last dosing for participants who were ongoing or completed the study treatment (including those who shorten the treatment based on response-guided therapy)
Time to premature treatment discontinuation for any reason (weeks) was calculated as follows: date of treatment discontinuation for any reason - first treatment administration date + 1/7. The estimated survivorship curves were obtained from Kaplan-Meier maximum likelihood estimates for each treatment group. Participants who completed the study treatment (including those who shorten the treatment based on response-guided therapy) were censored on their last dosing date.
Up to the treatment discontinuation or the date of the last dosing for participants who were ongoing or completed the study treatment (including those who shorten the treatment based on response-guided therapy)

Ramy czasowe: Baseline (Day 1 ), Weeks 2, 4, 6, 8, 12, 16, 24, 36, 48, 12 weeks post-treatment
WPAI-AS is a 6-question participant rated questionnaire to determine the amount of absenteeism, presenteeism, work productivity loss and daily activity impairment attributable to ankylosing spondylitis for a period of 7 days prior to each visit. It yields 4 sub-scores: work time missed (absenteeism), impairment while working (presenteeism or reduced on-the-job effectiveness), overall work impairment (work productivity loss or absenteeism plus presenteeism) and activity impairment (daily activity impairment). Each sub-scores was scaled as 0 (not affected/no impairment) to 10 (completely affected/impaired). Higher scores indicated greater impairment and less productivity.
