Who can join

Age: 50 and older, up to 100. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed informed consent must be obtained prior to participation in the study.
• Patient must be able to understand and communicate with the investigator and comply with the requirements of the study.
• Male or non-pregnant, non-lactating female patients at least 50 years of age.
• Diagnosis of GCA based on meeting all of the following criteria:
• Age at onset of disease ≥ 50 years.
• Unequivocal cranial symptoms of GCA (e.g., new-onset localized headache, scalp or temporal artery tenderness, permanent or temporary ischemia-related vision loss, or otherwise unexplained mouth or jaw pain upon mastication), and/or unequivocal symptoms of polymyalgia rheumatica (PMR) (defined as shoulder and/or hip girdle pain associated with inflammatory morning stiffness) and/or symptoms of limb ischemia (claudication).
• TAB revealing features of GCA and/or cross-sectional imaging study such as ultrasound (e.g., cranial or axillary), MRI/MRA, CTA, or PET-CT with evidence of vasculitis.
• Active disease as defined by meeting both of the following within 6 weeks of BSL (see Section 8.1 for details)
• Presence of signs or symptoms attributed to active GCA and not related to prior damage (e.g., visual loss that occurred prior to 6 weeks before BSL without new findings occurring within 6 weeks of BSL)
• Elevated ESR ≥ 30 mm/hr or CRP ≥ 10 mg/L attributed to active GCA or active GCA on TAB or on imaging study.
• Patients to meet definition of new-onset GCA or relapsing GCA:
• Definition of new-onset GCA*: GCA that is diagnosed within 6 weeks of BSL visit
• Definition relapsing GCA: GCA diagnosed > 6 weeks before BSL visit and following institution of an appropriate treatment course for GCA, participant has experienced recurrence of active symptoms or signs of disease after resolution.
• The 6-week timeframe is to be calculated from the date of suspected GCA diagnosis. Suspected diagnosis is defined as date when GC therapy was initiated.
• Patients' current GCA episode should be treatable with a dose of prednisone (or equivalent) designed to adequately achieve disease control in accordance with international guidelines. If this is not possible due to concerns regarding GC toxicity, the patient should not be enrolled. It must be medically appropriate for the patient to receive prednisone (or equivalent) 20 mg-60 mg daily (or equivalent) at BSL.
• Patients taking MTX (≤ 25 mg/week) are allowed to continue their medication provided they have taken it for at least 2 months and are on a stable dose for at least 4 weeks prior to randomization and if they are on stable folic acid treatment before randomization.

You may not qualify if…

• 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.
• Women of childbearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during study treatment or longer if required by locally approved prescribing information (e.g., in European Union (EU) 20 weeks after treatment discontinuation). Also, contraception should be used in accordance with locally approved prescribing information of concomitant medications administered (e.g., Rescue Treatment). Effective contraception methods include:
• Total abstinence (when this is in line with the preferred and usual lifestyle of the patient). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
• Bilateral oophorectomy with or without hysterectomy, total hysterectomy or bilateral salpingectomy at least 6 weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment are they not considered to be of child-bearing potential.
• Bilateral tubal occlusion, Bilateral tubal ligation (at least six weeks before taking study treatment.
• Male sterilization (vasectomy) of male partner(s) of the female participant at least 6 months prior to screening.
• Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps). NOTE: for United Kingdom: with spermicidal foam/gel/film/cream/vaginal suppository.
• 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.
• 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 participants 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 salpingectomy at least six weeks prior to first dose of study treatment in the study . 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 to be not of child-bearing potential.
• If local regulations are more stringent than the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the Informed Consent Form (ICF).
• Previous exposure to secukinumab or other biologic drug directly targeting IL-17 or IL-17 receptor.
• Patients treated with any cell-depleting therapies.
• Previous participation in a clinical trial where the outcome of treatment with the GCA drug is unknown. This does not include trials where the treatment for GCA was GCs, MTX, leflunomide or azathioprine
• Patients who have been treated with inhibitors directly targeting IL-1, or IL-1 receptor, IL-12 and IL-23, or abatacept within 4 weeks or within 5 half-lives of the drug (whichever is longer) prior to BSL.
• Treatment with tocilizumab, other IL-6/IL6-R inhibitor or JAK inhibitor within 12 weeks or within 5 half-lives of the drug (whichever is longer) prior to BSL, or if the patient did not respond to or experienced a relapse during treatment any time before BSL.
• Any treatment received for GCA in which patient did not respond to treatment or experienced a relapse while on that treatment any time before BSL. This also includes patients who were treated in a clinical trial for GCA. Patients who failed on treatment with GCs, MTX, leflunomide and/or azathioprine may be included.
• Patients treated with i.v. immunoglobulins or plasmapheresis within 8 weeks prior to BSL.
• Patients treated (i.e. systemic therapy) with cyclophosphamide or hydroxychloroquine within 6 months prior to BSL, or tacrolimus, everolimus, cyclosporine A, azathioprine, sulfasalazine, mycophenolate mofetil within 4 weeks prior to BSL.
• Patients treated with leflunomide within 8 weeks of BSL unless a cholestyramine washout has been performed in which case the patient must be treated within 4 weeks of BSL.
• Patients treated with an alkylating agent within 5 years prior to BSL, unless specified in other exclusion criteria.
• Patients requiring or anticipated to require systemic chronic glucocorticoid therapy or pulses of glucocorticoids for reasons other than GCA (e.g., COPD, asthma, planned surgery) at screening or randomization.
• Criterion removed in protocol V01.
• Patients requiring chronic (i.e., not occasional "prn") high potency opioid analgesics for pain management.
• Use of other investigational drugs within 5 half-lives of enrollment or within 30 days (e.g. small molecules) or until the expected pharmacodynamic effect has returned to BSL (e.g., biologics), whichever is longer; or longer if required by local regulations.
• History of hypersensitivity or contraindication to any of the study treatments or its excipients or to drugs of similar chemical classes.
