To compare reductions in MRI inflammation in the SIJs and spine from week 16 to 24 in patients who at week 16 are in ASDAS remission (defined as ASDAS inactive disease i.e. ASDAS<1.3) (i.e. continue sc. secukinumab 150 mg monthly) vs. not in ASDAS remission (i.e. increase sc. secukinumab 300 mg monthly). |

Several objectives, among others:
To compare changes in ASDAS and in MRI inflammation in the SIJs and spine from week 16 to 24 in patients who at week 16 are in ASDAS remission (i.e. continue sc. secukinumab 150 mg monthly) vs. not in ASDAS remission (i.e. increase to sc. secukinumab 300 mg monthly).
To compare changes in ASDAS and in MRI inflammation in the SIJs and spine from week 0 to 16 in patients who at week 16 are in ASDAS remission vs. not in ASDAS remission.
To describe the temporal changes on cMRI in MRI inflammation and structural lesions in the SIJs and spine from week 0 to week 56 in patients treated with secukinumab (cf. “treatment arms”). |

E.4 | Principal exclusion criteria |
1) Contraindications for secukinumab (described in protocol). 2) Contraindication for TNF inhibitor (described in protocol). 3) Contraindication for MRI (described in protocol). 4) Previous exposure to secukinumab or other biologic drug directly targeting IL-17 or IL-17 receptor 5) Previous exposure to TNF inhibitor or drug targeting TNF. 6) Previous exposure to other types of bDMARDs than TNF inhibitor (e.g. anti-interlukin 1, anti-interleukin 6, anti-interleukin 12/23, anti-interleukin 23, anti-CD20, co-stimulation inhibitors, JAK-inhibitors etc). 7) Patients taking high-potency opioid analgesics (e.g. methadone, hydromorphone, morphine) 8) Any change in the dose of oral corticosteroids in the last 4 weeks prior to the baseline visit or use of i.v. intramuscular or intra-articular corticosteroid during the last 8 weeks prior to the enrollment visit. 9) Use of any investigational drug and/or devices within 4 weeks before randomization or a period of 5 half-lives of the investigational drug, whichever is longer. 10) Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test. 11) Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during the entire study or longer if required by locally approved prescribing information (e.g. 20 weeks in EU). 12) Known recent drug or alcohol abuse. 13) Incapable of complying with the examination programme for physical or mental reasons. 14) Failure to provide written consent

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is defined as the proportion of patients with an improvement in MRI inflammation from week 16 to 24. This is defined as measured a positive change in MRI inflammation score ≥2 in the SIJs and spine, as assessed with the sum of SPARCC MRI SIJ and spine inflammation indices |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After completion of the last patient visit in the study |
|
E.5.2 | Secondary end point(s) |
1) Proportion of patients at week 16 and 24 who are in ASDAS remission respectively not in ASDAS remission. 2) Changes in ASDAS score from week 16 to 24 and from week 0 to 16, respectively. 3) Proportion of patients improving from week 16 to 24 (as measured by a positive change in MRI inflammation in the spine as assessed with the Canada-Denmark MRI system for assessment of inflammation). 4) Changes in MRI inflammation scores from week 0 to 16 and week 16 to 24, respectively (as measured by the SPARCC MRI SIJ and Spine Inflammation indices and the Canada-Denmark MRI system for assessment of inflammation). 5) Changes in scores/anatomical location of MRI lesions in the spine (as measured by the Canada-Denmark MRI system for assessment of inflammation, fat metaplasia, erosion, and new bone formation). 6) Changes in scores/anatomical location of MRI lesions in the SIJs (as measured by the SPARCC MRI SIJ Inflammation Index and SPARCC SIJ Structural Score (SSS) 7) MRI inflammation (as measured by the SPARCC MRI SIJ and Spine Inflammation indices and the Canada-Denmark MRI system for assessment of inflammation assessed on cMRI i.e. on STIR sequences on conventional and novel scan planes and on DWI sequences evaluated visually and based on regions of interest (ROIs)). |
