The MASES is the sum of all site scores (range 0 to 13); higher scores indicate more severe enthesitis. LS mean was derived from MMRM with treatment, geographic region, screening MRI/CRP status, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.
19. Change From Baseline in Severity of Peripheral Arthritis by Tender (TJC) and Swollen Joint Count (SJC) Scores of 44 Joints [ Time Frame: Baseline, Week 52 ]
    The number of tender and painful joints was determined by examination of 46 joints (23 joints on each side of the participants body). The 46 joints are assessed and classified as tender or not tender. Sum of all joints checked to be tender/painful divided by number of evaluable joints which is multiplied by 46 to obtain TJC score. The scores ranges from 0 (no tender/painful joints) to 46 (all joints tender/painful). Swollen joint count SJC was determined by examination of 44 joints (22 joints on each side of the participants body). The joints are classified as swollen or not swollen. Sum of all joints checked to be swollen divided by number of evaluable joints which is multiplied by 44 to obtain SJC score. Score ranges from 0 (not swollen) to 44 (all joints swollen). LS mean was derived from MMRM with treatment, geographic region, screening MRI/CRP status and baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.
20. Number of Participants With Anterior Uveitis [ Time Frame: Baseline through Week 52 ]

21. Change From Baseline in the Fatigue Numeric Rating Scale (NRS) Score [ Time Frame: Baseline, Week 52 ]
    The Fatigue Severity NRS is a participant-administered, single-item, 11-point horizontal scale anchored at 0 and 10, with 0 representing "no fatigue" and 10 representing "as bad as you can imagine". Participants rate their fatigue (feeling tired or worn out) by circling the one number that describes their worst level of fatigue during the previous 24 hours. LS Mean was derived from MMRM with treatment, geographic region, screening MRI/CRP status, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.
22. Change From Baseline in ASAS Health Index (ASAS HI) [ Time Frame: Baseline, Week 52 ]
    ASAS-HI is a disease-specific health-index instrument designed to assess the impact of interventions for SpA, including axSpA. The 17-item instrument has scores ranging from 0 (good health) to 17 (poor health). Each item consists of one question that the participant needs to respond to with either "I agree" (score of 1) or "I do not agree" (score of 0). A score of "1" is given where the item is affirmed, indicating adverse health. All item scores are summed to give a total score or index. LS Mean was derived MMRM with treatment, geographic region, screening MRI/CRP status, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.
23. Change From Baseline in the Jenkins Sleep Evaluation Questionnaire (JSEQ) [ Time Frame: Baseline, Week 52 ]
    Jenkins Sleep Evaluation Questionnaire (JSEQ) is a 4 item scale designed to estimate sleep problems in clinical research. The JSEQ assesses the frequency of sleep disturbance in 4 categories: 1) trouble falling asleep, 2) waking up several times during the night, 3) having trouble staying asleep (including waking up far too early), and 4) waking up after the usual amount of sleep feeling tired and worn out. Patients report the numbers of days they experience each of these problems in the past month on a 6 point Likert Scale ranging from 0 = "no days" to 5 = "22-30 days. The total JSEQ score ranges from 0 to 20, with higher scores indicating greater sleep disturbance. LS Mean was derived from using MMRM with treatment, geographic region, screening MRI/CRP status, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.
24. Change From Baseline in the Work Productivity Activity Impairment Spondyloarthritis (WPAI-SpA) Scores [ Time Frame: Baseline, Week 52 ]
    The WPAI-SpA consists of 6 questions to determine employment status, hours missed from work because of SpA, hours missed from work for other reasons, hours actually worked, the degree to which SpA affected work productivity while at work, and the degree to which SpA affected activities outside of work. The WPAI-SpA has been validated in the rad-axSpA patient population. Four scores are derived: percentage of absenteeism, percentage of presenteeism (reduced productivity while at work), an overall work impairment score that combines absenteeism and presenteeism, and percentage of impairment in activities performed outside of work. The computed percentage range for each sub-scale was from 0-100, with higher scores indicating greater impairment and less productivity. LS Mean was derived from ANCOVA with treatment, geographic region, screening MRI/CRP status and baseline value.
25. Change From Baseline in ASAS-Nonsteroidal Anti-Inflammatory Drug (NSAID) Score [ Time Frame: Baseline, Week 52 ]
    ASAS-NSAID score is used to present the NSAID intake by considering the type of NSAID, the total dose, & the number of days taking NSAID during a period of interest (PI). For NSAID equivalent scoring system, range is from 0 to 100, the higher the score, the greater the NSAID intake. ASAS-NSAID score= (equivalent NSAID score) x (days of intake during PI) x (days per week)/(PI in days).
26. Number of Participants With Treatment Emergent (TE) Anti-Ixekizumab Antibodies [ Time Frame: Week 52 ]
    A treatment-emergent positive anti-drug antibody (TE-ADA+) participant will be defined as a 4-fold increase over a positive baseline antibody titer (Tier 3); or for a negative baseline titer, a participant with an increase from the baseline to a level of ≥ 1:10.
27. Pharmacokinetics (PK): Trough Concentration at Steady State (Ctrough ss) [ Time Frame: Week 52 ]
    PK trough serum concentration samples were collected at steady state (Ctrough ss)
