| Ankylosing Spondylitis | Drug: 150 mg open-label secukinumab Drug: 150 mg double-blinded secukinumab Drug: 300 mg double-blinded secukinumab | Phase 4 |
The study used a multicenter design which included an initial 16 week open-label period (Treatment Period 1) followed by a randomized, double-blind, parallel-group period (Treatment Period 2),
- Screening: A Screening Period took place over 2 separate visits, with the first visit used to assess eligibility and to washout prohibited medications (up to 11 weeks). The second Screening Visit, which occurred at a minimum of 2 weeks prior to the Baseline Visit for all patients, was used to further assess eligibility and to initiate patients on the sensor actigraphy device and morning sleep questionnaires which collected data over the 2-week Screening Period to establish Baseline data. Note: Patients who did not require a washout, and who satisfied all inclusion and none of the exclusion criteria at the first Screening Visit, could initiate the second Screening Visit 1 (SV1) week after their first Screening Visit.
- Treatment Period 1: Patients who met all of the inclusion criteria and none of the exclusion criteria had a Baseline Visit performed to start Treatment Period 1. During this 16-week period, all patients received open-label secukinumab 150 mg (1 x 1.0mL subcutaneously [s.c.]) at Baseline, Weeks 1, 2, 3, 4, 8, and 12.
At Week 16, patients were placed into 1 of the following groups:
- Responders (Rs): Patients who achieved ASDAS inactive disease (total score < 1.3) at both Week 12 and Week 16 and who achieved a decrease (improvement) from Baseline in total ASDAS score at both Week 12 and Week 16.
- Inadequate responders (IRs): Patients who had active disease, defined as an ASDAS total score of ≥ 1.3 at either Week 12 or Week 16, and who achieved a decrease (improvement) from Baseline in total ASDAS score at both Week 12 and Week 16.
- Nonresponders: Patients who exhibited no change or an increase (worsening) from Baseline in total ASDAS score at either Week 12 or Week 16.
Note: To minimize patient burden, at the Week 16 Visit, the hs-CRP measurement that is part of the ASDAS calculation was imputed from the Week 12 hs-CRP results to allow for assignment into the groups above. Historically, hs-CRP levels have varied little between Week 12 and Week 16 or in previous studies of secukinumab in active AS.
1. Treatment Period 2: Upon completion of the Week 16 visit,
- Responders entered Treatment Period 2 and continued to receive secukinumab 150 mg every 4 weeks through Week 48 as well as 1 matched placebo dose (s.c. injection) to maintain the integrity of the blind for the randomized IR group.
- Inadequate responders entered Treatment Period 2 and were randomized (1:1, double blinded) to secukinumab 300 mg or secukinumab 150 mg every 4 weeks through Week 48. Patients knew that they were on secukinumab, but were blinded to dose, so they did not know whether they were receiving 150 mg or 300 mg.
- Nonresponders were discontinued from the study at Week 16. The only condition that was placed on enrollment targets was that no less than 60% of patients (162 patients) were tumor necrosis factor alpha (TNFα) inhibitor naive (or, no more than 40% of patients were TNF-IR). In theory the percentage of TNFα inhibitor naive patients could have reached 100%, although that was not anticipated.
Patients could discontinue the study at any time. If rescue treatment with prohibited medications (as described in Section 9.4.7) occurred, patients were discontinued from the study and were to return for an End of Study Visit. The End of Study Visit was scheduled approximately 4 weeks after the last study treatment and was performed before any new treatment was initiated. After the End of Study Visit, any serious adverse events (SAEs) that occurred in the following 30 days were required to be reported.

- The Proportion of Participants Who Achieved Inactive Disease Based on the Ankylosing Spondylitis Disease Activity Score (ASDAS) Measure [ Time Frame: Week 52 ]
Proportion of participants with inadequate response at week 16 who achieved inactive disease at Week 52 The Ankylosing Spondylitis Disease Activity Score (ASDAS) is a composite index to assess disease activity in AS. The ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score) were utilized to assess the disease activity status.
- < 1.3 between inactive disease and moderate disease activity,
- < 2.1 between moderate disease activity and high disease activity, and
- 3.5 between high disease activity and very high disease activity.
- The Proportion of Participants Who Achieved a Clinically Important Improvement on the Ankylosing Spondylitis Disease Activity Score (ASDAS) Scale [ Time Frame: Baseline, Week 52 ]
A reduction from baseline in ASDAS score of ≥1.1 was considered a clinically important improvement in disease activity in Ankylosing Spondylitis. In this study, ASDAS is used to estimate the difference in response between 150mg and 300mg of secukinumab.
The Ankylosing Spondylitis Disease Activity Score (ASDAS) is a composite index to assess disease activity in AS. The ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score) wias utilized to assess the disease activity status.
- < 1.3 between inactive disease and moderate disease activity,
- < 2.1 between moderate disease activity and high disease activity, and
- 3.5 between high disease activity and very high disease activity.
- Change in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) [ Time Frame: Baseline, Week 52 ]BASDAI is a validated assessment tool using 0 through 10 scales (0 indicating "no problem" and 10 indicating "worst problem"), to characterize six clinical domains pertaining to five major symptoms of AS perceived by the patients. Computed composite scores of 4 or greater indicate suboptimal disease control. In this study, BASDAI is used to estimate the difference in response between 150mg and 300mg of secukinumab.
- Proportion of Patients Who Achieved Bath Ankylosing Spondylitis Disease Activity Index 50 (BASDAI-50) [ Time Frame: Baseline, Week 52 ]BASDAI-50 represents a change from baseline (improvement) of at least 50% in BASDAI score. In this study, BASDAI is used to estimate the difference in response between 150mg and 300mg of secukinumab.
- The Proportion of Participants Who Achieved an ASAS 20 Response (Assessment of SpondyloArthritis International Society Criteria) [ Time Frame: Week 52 ]
ASAS 20 response is a validated composite assessment, reflecting the proportion of treated patients who achieve within a defined time frame at least 20% improvement in score in at least 3 of a conventional set of 4 clinical domains relevant to AS and no worsening in the fourth domain. In this study, ASAS20 is used to estimate the difference in response between 150mg and 300mg of secukinumab.
An ASAS20 response is defined as an improvement of ≥20% from baseline and absolute improvement from baseline of at least 1 on a 0-to-10 scale in at least 3 of the following 4 domains: patient global, total back pain, function (BASFI), and inflammation (average of the last 2 questions of the BASDAI concerning morning stiffness). An absence of deterioration from baseline (deterioration defines as ≥20% worsening and absolute worsening of at last 1 on a 0-to-10 scale) in the potential remaining domain.
- The Proportion of Participants Who Achieved an ASAS 40 Response [ Time Frame: Week 52 ]
ASAS 40 response is a validated composite assessment, reflecting the proportion of treated patients who achieve within a defined time frame at least 40% improvement in score in at least 3 of a conventional set of 4 clinical domains relevant to AS and no worsening in the fourth domain. In this study, ASAS40 is used to estimate the difference in response between 150mg and 300mg of secukinumab.
An ASAS40 response is defined as a ≥40% improvement in 3 of the 4 domains with an absolute improvement of at least 2 on a 0-to-10 scale, and no worsening in the remaining domain.
- The Proportion of Patients Who Achieved an ASAS Partial Remission [ Time Frame: Week 52 ]The ASAS partial remission criteria are defined as a value not above 2 units in each of the four main domains on a scale of 0-10. In this study, ASAS partial remission is used to estimate the difference in response between 150mg and 300mg of secukinumab.
- Change in ASAS - Health Index Over Time [ Time Frame: Baseline, Week 52 ]The ASAS-HI is a self-administered questionnaire and measures functioning and health over 17 aspects of health and 9 environmental factors in patients with spondyloarthritis. Patients score each item as "I agree" and "I do not agree". In this study, ASAS-HI is used to estimate the difference in response between 150mg and 300mg of secukinumab. Lower score indicating a better health status
- Change in Functional Assessment of Chronic Illness Therapy (FACIT) - Fatigue Over Time [ Time Frame: Baseline, Week 52 ]Fatigue was assessed using the 13-item FACIT-fatigue scale for the assessment of fatigue in cancer patients.24 The FACIT-Fatigue is a validated questionnaire that was originally developed for the precise evaluation of fatigue levels in cancer patients with anemia. It consists of 13 questions using a 5 point scale (0=not at all; 1 = a little bit, 2 = somewhat, 3 = quite a bit and 4 = very much). Responses to each question were added with equal weight to obtain a total score. The range of possible scores is 0-52, with 0 corresponding to the highest level of fatigue and 52 corresponding to the lowest level of fatigue.
