5. Prior exposure to TNF-i's or other biologic immunomodulating agents, investigational or approved
6. Active ongoing inflammatory diseases other than pSpA that might confound the evaluation of the benefit of secukinumab therapy (e.g., uveitis).

8. Diagnosis of synovitis associated with primary osteoarthritis
9. Diagnosis of septic arthritis, sarcoidosis, seronegative RA, or erosive osteoarthritis
10. Current severe progressive or uncontrolled disease, which in the judgment of the clinical investigator renders the particpant unsuitable for the trial.

11. History of clinically significant liver disease or liver injury indicated by abnormal liver function tests, such as SGOT (AST), SGPT/ Alanine transaminase (ALT), Alkaline

    phosphatase (ALP) and serum bilirubin. The investigator should be guided by the following criteria:

    • Any single parameter may not exceed 2 x the upper limit of normal (ULN). A single parameter elevated up to and including 2 x ULN should be re-checked once more as soon as possible, and in all cases, at least prior to randomization, to rule-out laboratory error.
    • If the total bilirubin concentration is increased above 2 x ULN, total bilirubin should be differentiated into the direct and indirect reacting bilirubin. In any case, serum bilirubin should not exceed the value of 1.6 mg/dL (27 µmol/L).
12. Screening total White Blood Cells (WBC) count <3,000/μl, or platelets <100,000/μl or neutrophils <1,500/μl or hemoglobin <8.5 g/dl (85 g/L).
13. Plans for administration of live vaccines during the study period or 6 weeks prior to randomization.
14. Significant medical problems or diseases, including but not limited to the following: uncontrolled hypertension (≥160/95 mmHg), congestive heart failure (New York Heart Association status of class III or IV), uncontrolled diabetes, or very poor functional status precluding ability to perform self-care.
15. 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.
16. History or evidence of ongoing alcohol or drug abuse, within the last six months before randomization.

17. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during dosing of study treatment. Effective contraception methods include:

    • Total abstinence (when this is in line with the preferred and usual lifestyle of the participant. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post- ovulation methods) and withdrawal are not acceptable methods of contraception
    • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or bilateral tubal ligation at least six weeks before taking investigational drug. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
    • Male sterilization (at least 6 months prior to screening). For female participants on the study, the vasectomized male partner should be the sole partner for that participant
    • Barrier methods of contraception: Condom or Occlusive cap (e.g. diaphragm or cervical/vault caps)
    • Use of oral, (estrogen and progesterone), injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS).

    In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.

    NOTE:

    Women are considered post-menopausal if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate history of vasomotor symptoms). Women are considered not of child bearing potential if they are post-menopausal or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or bilateral tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

    If local regulations deviate from the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the ICF.

18. Previous treatment with any cell-depleting therapies including but not limited to anti- CD20 or investigational agents (e.g., CAMPATH, anti-CD4, anti-CD5, anti-CD3, anti- CD19).
19. Use of other investigational drugs at the time of enrollment, or within 5 half- lives of enrollment, or within 4 weeks until the expected pharmacodynamic effect has returned to baseline, whichever is longer; or longer if required by local regulations.
20. Use or planned use of prohibited concomitant medication (see Section 6.2.2).
21. History of lymphoproliferative disease or any known malignancy, or history of malignancy of any organ system treated or untreated within the past 5 years, regardless of whether there is evidence of local recurrence or metastases (except for skin Bowen's disease, or basal cell carcinoma or actinic keratosis that have been treated with no evidence of recurrence in the past 12 weeks; carcinoma in situ of the cervix or non- invasive malignant colon polyps that have been removed).
22. Presence of significant medical problems which in the opinion of the investigator will interfere with study participation, including but not limited to the following: participants with severely reduced kidney function (estimated glomerular filtration rate (eGFR) <29 ml/min/1.73m2).
23. History of hypersensitivity to any of the study drug constituents.
24. Any medical or psychiatric condition, which, in the investigator's opinion, would preclude the participant from adhering to the protocol or completing the study per protocol.
25. Chest X-ray or MRI (at Screening Visit 1) with evidence of ongoing infectious or malignant process obtained within 3 months of screening and evaluated by a qualified physician.
26. Active systemic infection during the last two weeks (exception: common cold) prior to randomization or any infection that reoccurs on a regular basis.
27. Underlying conditions (including, but not limited to metabolic, hematologic, renal, hepatic, pulmonary, neurologic, endocrine, cardiac, infectious or gastrointestinal) which in the opinion of the investigator significantly immunocompromises the participant and/or places the participant at unacceptable risk for receiving an immunomodulatory therapy
28. Known infection with Human Immunodeficiency Virus (HIV), hepatitis B or hepatitis C at screening or randomization.
29. History of ongoing, chronic or recurrent infectious disease or evidence of tuberculosis infection as defined by a positive QuantiFERON TB-Gold test as indicated in the assessment schedule. Participants with a positive test may participate in the study if further work up (according to local practice/guidelines) establishes conclusively that the participant has no evidence of active tuberculosis. After active tuberculosis has been excluded, treatment for latent tuberculosis according to local country guidelines must have been initiated prior to enrollment.
