Brief Summary:
This study assessed the clinical Assessment of SpondyloArthritis international Society (ASAS) 20 response to secukinumab and evaluated to which extent concomitant nonsteroidal anti-inflammatory drug (NSAID) treatment can be reduced in patients treated with secukinumab or placebo following an initial run-in phase of stable NSAID therapy.

Condition or disease Intervention/treatment Phase
Ankylosing Spondylitis Drug: Secukinumab (AIN457) 150 mg s.c. Drug: Placebo - Secukinumab (AIN457) 150 mg s.c. Phase 4

Detailed Description:

This was a phase IV, 20-week, randomized, double-blind, 3-arm, placebo-controlled, parallel-group, multicenter study to examine the clinical response of secukinumab treatment in patients with ankylosing spondylitis as measured by the Assessment of SpondyloArthritis international Society (ASAS) 20 response and the nonsteroidal anti-inflammatory drug (NSAID)-sparing effect. This study evaluated to which extent nonsteroidal anti-inflammatory drug (NSAID) treatment can be reduced between Week 4 and Week 12 in patients randomized to secukinumab 150 mg or placebo following an initial run-in phase of 4 weeks on stable NSAID therapy. Two NSAID tapering approaches were evaluated in this study:

  1. an early tapering approach in which NSAID were tapered at the start of secukinumab treatment,
  2. a delayed tapering approach in which NSAID were tapered following 4 weeks of secukinumab treatment.

Patients were randomized 1:1:1 to one of the following treatment groups:

  • Secukinumab - delayed NSAID tapering: Induction with secukinumab 150 mg s.c. once per week (Week 0, 1, 2, 3 and 4) followed by maintenance with secukinumab 150 mg s.c. every 4 weeks (Week 8, 12, 16 and 20), with intermittent placebo injections at Week 5, 6, 7, 17, 18 and 19 to maintain the blind. NSAID tapering allowed from Week 4 (delayed tapering).
  • Secukinumab - early NSAID tapering: Placebo at weeks 0, 1, 2, 3 to maintain the blind; followed by induction with secukinumab 150 mg s.c. once per week (Week 4, 5, 6, 7, 8) and maintenance with secukinumab 150 mg s.c. every 4 weeks (Week 12, 16 and 20), with intermittent placebo injections at Week 17, 18 and 19 to maintain the blind. NSAID tapering allowed from Week 4 (early tapering).
  • Placebo: Placebo s.c. at Week 0, 1, 2, 3, 4, 5, 6, 7, 8 and 12. After the Week 16 assessments of the secondary endpoint had been performed, these patients received weekly doses of secukinumab 150 mg s.c. (Week 16, 17, 18, 19 and 20). NSAID tapering allowed from Week 4.

The primary objective of the study was to demonstrate that the efficacy of secukinumab 150 mg subcutaneous (s.c.) injection (with NSAID tapering) is superior to placebo based on the proportion of patients achieving an ASAS20 response at Week 12. To show superiority, both secukinumab treatment arms were pooled and compared against placebo.

Primary Outcome Measures :
  1. Proportion of Patients Who Achieved ASAS20 Response in the Pooled Secukinumab Group Compared With the Placebo Group at Week 12 [ Time Frame: Baseline, Week 12 ]

    ASAS (Assessment of SpondyloArthritis International Society criteria) 20 response is defined as an improvement from baseline of ≥20% and ≥1 unit on a scale of 0-10 in at least three of the four ASAS main domains and no worsening of ≥20% and ≥1 unit on a scale of 0-10 in the remaining domain. The four main ASAS domains are: Patient's global assessment of disease activity, back pain, function represented by ability to perform specific tasks (from Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]) and inflammation represented by mean duration and severity of morning stiffness.

    Non-responder imputation was applied for missing data.



Secondary Outcome Measures :
  1. Proportion of Patients Who Achieved ASAS20 Response in Each Secukinumab Group (Delayed NSAID Tapering and Early NSAID Tapering) Compared With the Placebo Group [ Time Frame: Baseline, Week 12, Week 16 ]

    ASAS (Assessment of SpondyloArthritis International Society criteria) 20 response is defined as an improvement from baseline of ≥20% and ≥1 unit on a scale of 0-10 in at least three of the four ASAS main domains and no worsening of ≥20% and ≥1 unit on a scale of 0-10 in the remaining domain. The four main ASAS domains are: Patient's global assessment of disease activity, back pain, function represented by ability to perform specific tasks (from Bath Ankylosing Spondylitis Disease Activity Index [BASDAI]) and inflammation represented by mean duration and severity of morning stiffness.

    Non-responder imputation was applied for missing data.


  2. Mean Change From Baseline in ASAS-NSAID Score at Week 12 [ Time Frame: Baseline, Week 12 ]

    ASAS-NSAID score is used to present the NSAID (nonsteroidal anti-inflammatory drug) intake by considering the type of NSAID, the total dose and the number of days taking NSAID during a period of interest (PI). For the NSAID equivalence scoring system, "no NSAID intake" was set to a score value of 0, and the reference dose of 150 mg/day diclofenac was set to a score value of 100. The Daily diclofenac-equivalent dose score was derived by converting each daily dose of NSAID to a percentage dose equivalent of 150 mg diclofenac. ASAS-NSAID score = (equivalent NSAID score) x (days of intake during PI) x (days per week)/(PI in days).

    A negative change from baseline indicates less NSAID consumption.


  3. Mean Change From Baseline in ASAS-NSAID Score in Each Secukinumab Group After 12 Weeks of Exposure (at Week 12 in the Secukinumab-delayed NSAID Tapering Group and at Week 16 in the Secukinumab-early NSAID Tapering Group) [ Time Frame: Baseline, Week 12 (delayed NSAID tapering), Week 16 (early NSAID tapering) ]

    ASAS-NSAID score is used to present the NSAID (nonsteroidal anti-inflammatory drug) intake by considering the type of NSAID, the total dose and the number of days taking NSAID during a period of interest (PI). For the NSAID equivalence scoring system, "no NSAID intake" was set to a score value of 0, and the reference dose of 150 mg/day diclofenac was set to a score value of 100. The Daily diclofenac-equivalent dose score was derived by converting each daily dose of NSAID to a percentage dose equivalent of 150 mg diclofenac. ASAS-NSAID score = (equivalent NSAID score) x (days of intake during PI) x (days per week)/(PI in days).

    A negative change from baseline indicates less NSAID consumption. For this endpoint the analysis was performed after 12 weeks of exposure to secukinumab which was achieved at Week 12 in the secukinumab delayed NSAID tapering group but at Week 16 in the secukinumab early NSAID tapering group.


  4. Mean Change From Baseline in the BASDAI Total Score [ Time Frame: Baseline, Week 12, Week 16 ]

    The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) is a participant-reported assessment consisting of 6 questions that relate to 5 major symptoms relevant to ankylosing spondylitis: 1) Fatigue, 2) Spinal pain, 3) Peripheral arthritis, 4) Enthesitis, 5) Intensity, and 6) Duration of morning stiffness. Participants need to score each item with a score from 0 to 10 (captured as a continuous visual analog scale). Total score is obtained from the average of symptom scores ranging 0 (no problem) to 10 (worst problem), with a higher score indicating more severe symptoms.

    A negative change from baseline in the total 0-10 BASDAI score indicates improvement.


  5. Mean Change From Baseline in Health-related Quality of Life as Measured by the Short Form-36 Health Survey (SF-36) Physical Component Summary (PCS) Score [ Time Frame: Baseline, Week 12 ]
    The Short Form-36 Health Survey (SF-36) measures the impact of disease on overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 comprise the physical component of the SF-36 (SF-36 PCS) that is evaluated in this study. Scores on each item 1-4 were summed and averaged (range = 0-100 with higher scores indicating better levels of function and/or better health). A positive change from Baseline indicates improvement.
