Brief Summary
-----------------
This 3-year extension study aims at making available the treatment with secukinumab in prefilled syringes (PFS) to patients with ankylosing spondylitis who took part in phase III study CAIN457F2305, defined as core study, as well as to generate additional data on the sustainability of clinical benefits, safety and tolerability during long-term administration of secukinumab.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessment of Spondyloarthritis International Society Criteria (ASAS) 20 Response From Week 104 to Week 260 | 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, ASAS 20 is used to assess quantitatively the sustainability of clinical benefits of two dosage regimens of secukinumab over the treatment period from Week 104 to Week 260 No Statistical Analysis was performed This was the total for Group 1 Participants that up-titrated are counted only at the originally randomized treatment group. | Week 104 to Week 260 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessment of Spondyloarthritis International Society Criteria (ASAS) 40 Response From Week 104 to Week 260 | 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, ASAS 40 is used to assess quantitatively the sustainability of clinical benefits of two dosage regimens of secukinumab over the treatment period from Week 104 to Week 260 No Statistical Analysis was performed This was the total for Group 1 Participants that up-titrated are counted only at the originally randomized treatment group | Week 104 to Week 260 |
