Brief summary
The purpose of this study was to demonstrate the clinical efficacy, safety and tolerability of secukinumab compared to placebo in patients with nr-axSpA at Week 16 as well as Week 52 and long term efficacy and safety up to Week 104 (core phase) followed by an optional extension phase consisting of a 16-week randomized dose escalation treatment period and a continuous treatment period for up to Week 208
Detailed description
Patients were randomized to one of three treatment groups (1:1:1) in the core phase: * Secukinumab 150 mg Load: secukinumab 150 mg (1 mL, 150 mg/mL) s.c. pre-filled syringe (PFS) at baseline, Weeks 1, 2, and 3, followed by administration every four weeks starting at Week 4 * Secukinumab 150 mg No Load: secukinumab 150 mg (1 mL, 150 mg/mL) s.c. PFS at baseline, placebo at Weeks 1, 2, and 3, followed by secukinumab 150 mg PFS administration every four weeks starting at Week 4 * Placebo: placebo (1 mL) s.c. PFS at baseline, Weeks 1, 2, 3, followed by administration every four weeks starting at Week 4. All patients received secukinumab 150 mg as open-label treatment from Week 52 up to Week 100, unless they had discontinued study treatment. At Week 104, all patients who finished the core phase according to the protocol were asked to continue in an optional, exploratory extension phase. Patients who achieved ASAS20 response at Week 104 (Core Phase Responders) were randomized to the following treatment groups (blinded) in the extension phase: * Core Phase Responder 150 mg: secukinumab 150 mg (1 mL, 150 mg/mL) s.c. PFS and placebo (1 mL) s.c. PFS every four weeks; * Core Phase Responder 300 mg: 2 injections with secukinumab 150 mg (1 mL, 150 mg/mL) s.c. PFS every four weeks. Core Phase Non-Responders (not achieving ASAS20 at Week 104) were escalated to secukinumab 300 mg in an open-label manner. \- Core Phase Non-Responder 300 mg: 2 injections with secukinumab 150 mg (1 mL, 150 mg/mL) s.c. PFS every four weeks open-label. Starting from Week 156 onward, a patient could switch to secukinumab 300 mg open-label based on the clinical judgment of disease activity by the investigator.

Approximately 555 patients were randomized to one of three treatment groups (secukinumab 150 mg Load, secukinumab 150 mg No Load or placebo in a ratio of 1:1:1): * Group 1 (secukinumab 150 mg Load): secukinumab 150 mg (1 mL, 150 mg/mL) s.c. prefilled syringe (PFS) at baseline (BSL), Weeks 1, 2 and 3, followed by administration every four weeks starting at Week 4 * Group 2 (secukinumab 150 mg No Load): secukinumab 150 mg (1 mL, 150 mg/mL) s.c. PFS at BSL, placebo at Weeks 1, 2 and 3, followed by secukinumab 150 mg PFS administration every four weeks starting at Week 4 * Group 3 (placebo): placebo (1 mL) s.c. PFS at BSL, Weeks 1, 2, 3, followed by administration every four weeks starting at Week 4 Based on the clinical judgment of disease activity by the investigator and the patient, background medications, such as NSAIDs and DMARDs, may have been modified or added to treat signs and symptoms of nr-axSpA from Week 16 on.

| Change in Bath Ankylosing Spondylitis Functional Index (BASFI) | Baseline and Week 16 | The Bath Ankylosing Spondylitis Functional Index (BASFI) is a set of 10 questions designed to determine the degree of functional limitation in those subjects with AS. The ten questions were chosen with a major input from subjects with AS. The first 8 questions consider activities related to functional anatomy. The final 2 questions assess the subjects' ability to cope with everyday life. A 100 mm visual analog scale (VAS) is used to answer the questions. The mean of the ten questions gives the BASFI score - a value between 0 and 10. (0 being no problem and 10 being the worst problem, captured as a continuous visual analog scale (VAS)). A higher score on the VAS signifies higher severity. |
| The Number and Percentage of Patients to Achieve a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 50 Response | Week 16 and 52 | The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) consists of a 0 through 10 scale (0 being no problem and 10 being the worst problem, captured as a continuous VAS), which is used to answer 6 questions pertaining to the 5 major symptoms of AS. The BASDAI 50 is defined as an improvement of at least 50% in the BASDAI compared to baseline. A higher score on the VAS signifies higher severity. |
| Change in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) | Baseline and Week 16 | The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a validated assessment tool using 1 through 10 scales (1 indicating no problem and 10 indicating worst problem), to characterize six clinical domains (fatigue, spinal pain, joint pain/selling, localized tenderness, morning stiffness duration, morning stiffness severity) pertaining to five major symptoms of Ankylosing Spondylitis (AS). The computed final BASDAI score is a value between 0 and 10 with a higher score indicating worse disease. A higher score on the VAS signifies higher severity. |

A single point is assigned for each yes response and no points for each no response resulting in overall scores that range from 0 (least severity) to 18 (highest severity). As such, lower score indicate better quality of life. Items include an assessment of mobility/energy, self-care and mood/emotion. The recall period is at the moment, and the measure requires approximately 6 minutes to complete. |

Higher score indicates worse symptoms. The formula is: ASDAS-CRP = 0.121 x total back pain + 0.110 x patient global + 0.073 x peripheral pain/swelling + 0.058 x duration of morning stiffness + 0.579 x ln(hsCRP +1) |

It consists of eight subscales (domains) that can be scored individually: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role- Emotional, and Mental Health. Two overall summary scores, the Physical Component Summary (PCS) and the Mental Component Summary (MCS) also can be computed.

Change in Ankylosing Spondylitis Quality of Life (ASQoL) Scores at Week 16
The Ankylosing Spondylitis Quality of Life scores (ASQoL) is a self-administered questionnaire designed to assess health-related quality of life in adult patients with Ankylosing Spondylitis. The ASQoL contains 18 items with a dichotomous yes/no response option. A single point is assigned for each yes response and no points for each no response resulting in overall scores that range from 0 (least severity) to 18 (highest severity). As such, lower score indicate better quality of life. Items include an assessment of mobility/energy, self-care and mood/emotion. The recall period is at the moment, and the measure requires approximately 6 minutes to complete.

The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a validated assessment tool using 1 through 10 scales (1 indicating no problem and 10 indicating worst problem), to characterize six clinical domains (fatigue, spinal pain, joint pain/selling, localized tenderness, morning stiffness duration, morning stiffness severity) pertaining to five major symptoms of Ankylosing Spondylitis (AS). The computed final BASDAI score is a value between 0 and 10 with a higher score indicating worse disease. A higher score on the VAS signifies higher severity.

Change in Bath Ankylosing Spondylitis Functional Index (BASFI)
The Bath Ankylosing Spondylitis Functional Index (BASFI) is a set of 10 questions designed to determine the degree of functional limitation in those subjects with AS. The ten questions were chosen with a major input from subjects with AS. The first 8 questions consider activities related to functional anatomy. The final 2 questions assess the subjects' ability to cope with everyday life. A 100 mm visual analog scale (VAS) is used to answer the questions. The mean of the ten questions gives the BASFI score - a value between 0 and 10. (0 being no problem and 10 being the worst problem, captured as a continuous visual analog scale (VAS)). A higher score on the VAS signifies higher severity.

Change in Short Form-36 Physical Component Summary (SF-36 PCS)
The Short Form-36 Physical Component Summary (SF-36 PCS) is an instrument to measure health-related quality of life among healthy patients and patients with acute and chronic conditions. It consists of eight subscales (domains) that can be scored individually: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role- Emotional, and Mental Health. Two overall summary scores, the Physical Component Summary (PCS) and the Mental Component Summary (MCS) also can be computed. The eight domains are based on a scale from 0-100 while PCS and MCS are norm-based scores with a mean of 50 and a standard deviation of 10. Higher scores indicate a higher level of functioning. A positive change from baseline score indicates an improvement.
