Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of participants that achieve 50% improvement of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at Week 24	This accounts for participants achieving 50% improvement in BASDAI.	24 Weeks after initiation of Humira therapy
Secondary	Percentages of participants who achieve major improvement of Ankylosing Spondylitis Disease Activity Score (ASDAS) at Week 24	The ASDAS tool is a self-administered questionnaire plus an objective laboratory evaluation.	24 Weeks after initiation of Humira therapy
Secondary	Percentages of participants who achieve clinically important improvement of Ankylosing Spondylitis Disease Activity Score (ASDAS) at Week 24	The ASDAS tool is a self-administered questionnaire plus an objective laboratory evaluation.	24 Weeks after initiation of Humira therapy
Secondary	Percentage of participants that achieve 50% improvement of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)	This accounts for participants achieving 50% improvement in BASDAI.	Every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Percentages of participants who achieve clinically important improvement of Ankylosing Spondylitis Disease Activity Score (ASDAS)	The ASDAS tool is a self-administered questionnaire plus an objective laboratory evaluation.	Every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Percentages of participants who achieve major improvement of Ankylosing Spondylitis Disease Activity Score (ASDAS)	The ASDAS tool is a self-administered questionnaire plus an objective laboratory evaluation.	Every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Percentages of participants whose disease activity states are inactive per ASDAS score	The ASDAS tool is a self-administered questionnaire plus an objective laboratory evaluation.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Percentages of participants whose disease activity states are moderate per ASDAS score	The ASDAS tool is a self-administered questionnaire plus an objective laboratory evaluation.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Changes of the frequency of overall extra-articular manifestations (EAM) of interest	The change of the frequency of overall extra-articular manifestations (EAM) will be assessed.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Changes of the respective frequency of each EAM	The changes of the respective frequency of each EAM will be assessed.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Changes in the percentage of participants who have enthesitis of the plantar fascia or Achilles tendon	The change in the percentage of participants who have enthesitis of the plantar fascia or Achilles tendon will be assessed.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Change in Maastricht Ankylosing Spondylitis Enthesitis Score (MASES)	The change in MASES score will be assessed.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Change in Tender Joint Counts (TJC)	The change of TJC (0-46), in participants who had peripheral arthritis (=1 swollen joint) at baseline will be assessed.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
Secondary	Change in Swollen Joint Counts (SJC)	The change of SJC (0-44), in participants who had peripheral arthritis (=1 swollen joint) at baseline will be assessed.	At Week 0 (Baseline) and every 12 weeks' follow-up after initiation of Humira therapy (approximately up to 58 weeks)
