Eligibility Criteria:
Inclusion Criteria:
1. Patients ≥15 years
2. Signed informed consent
3. Affiliation with the French national social security system.
4. Adequate and effective contraceptive measures based on CTFG update of recommendations version 1.1 dated 21-Sep-2020
5. For women of childbearing age, a negative serum or urinary pregnancy test.
6. Diagnosis of TAK based on the 2022 American College of Rheumatology/EULAR and/or Ishikawa criteria modified by Sharma (Appendix 1) for patients with age ≥ 18 years and based the PRINTO/EULAR/PReS criteria for patients with age between 15 and 17 years
7. Active TAK defined by a National Institutes of Health \[NIH\] score \>1 in the past 2 months (Appendix 2)
8. Severe TAK, defined as either refractory/relapsing disease or by the presence of severe arterial involvement at baseline.
1. refractory/relapsing disease is defined as the recurrence or persistence of vasculitis activity confirmed by a specialized physician despite adequate corticosteroid tapering (i.e., inability to taper corticosteroids below 1mg/kg/day within 1 month due to disease activity, or inability to taper corticosteroids below 10mg/day within 6 months, or inability to discontinue corticosteroids after 1 year of treatment, or relapse of disease during/after gradual decrease of corticosteroids therapy) and/or immunosuppressive treatment (e.g., azathioprine, methotrexate, mycophenolate mofetil, leflunomide)
2. Severe arterial involvement is defined by the presence of stroke, retinopathy, coronary artery stenosis, pulmonary artery stenosis, mesenteric arteries or celiac trunk stenosis, renal artery stenosis or limb ischemia at baseline.
9. Patients must be eligible to receive prednisone (or equivalent) 10-50 mg daily at baseline. Oral corticosteroids must be at a stable dose for at least 2 weeks prior to the first administration of study drug at Day 0.
10. Absence of chronic active infections. Patients with a positive TB test may participate in the study if further work up (according to local practice/guidelines) conclusively establishes that the patient has no evidence of active tuberculosis. If the test result is indeterminate, the investigator may repeat the test once or may proceed directly to perform the work-up for TB as per local procedure. If presence of latent tuberculosis is established then treatment according to local country guidelines must be initiated prior to randomization
Exclusion Criteria:
1. Inability to comply with study guidelines or provide informed consent
2. 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 child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception while taking study treatment and for 6 months after stopping of investigational drug. Highly 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, symptotherma), post- ovulation methods) and withdrawal are not acceptable methods of contraception.
* Female bilateral tubal ligation, female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or total hysterectomy at least six 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.
* 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.
* Use of oral (estrogen and progesterone), injected, or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate \< 1%), for example hormone vaginal ring or transdermal hormone contraception.
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.
Contraception should be used in accordance with locally approved prescribing information of concomitant medications administered.
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 of not 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 informed consent form (ICF).
Sexually active males, unless they agree to use barrier protection during intercourse with a woman of child-bearing potential, while taking study treatment. As condom use alone has a reported failure rate exceeding 1% per year, it is recommended that female partners of male study participants use a second method of birth control.
Globally, for all sexually active males, contraception should be used in accordance with the locally approved prescribing information of concomitant medications administeredPregnancy or breastfeeding;
3. History of severe immunosuppression, positive serology for HIV or positive HBsAg
4. Infection requiring treatment with intravenous antibiotics within 2 weeks prior to the inclusion \& randomization visit
5. Contraindication or hypersensitivity to Secukinumab, TNF inhibitors or tocilizumab, corticosteroids, TB prophylactic treatment or to any of their excipients. For contra-indications related to the standard of care medications refer to the summary of each Product Characteristics (SmPC) refer to EMA links (7.1.2)
6. Have received live vaccines within 3 months prior to inclusion
7. Indication to initiate infliximab, adalimumab, tocilizumab, secukinumab for another active disease than Takayasu arteritis (retained)
8. Use of the following systemic treatments during the specified periods
1. Treatment with biologic therapy secukinumab, within 3 months prior to the inclusion \& randomization visit
2. Treatment with any systemic alkylating agents within 3 months prior to the inclusion \& randomization visit (e.g., cyclophosphamide, chlorambucil)
9. Presence of any of the following on-ongoing and on-treatment disease processes (vasculitis and auto- immunes disease):
Microscopic polyangiitis
* Granulomatosis with polyangiitis Eosinophilic granulomatosis with polyangiitis
* Polyarteritis nodosa o Cogan's syndrome
* Behcet's disease
* Kawasaki's disease
* Atypical mycobacterial infections
* Deep fungal infections o Lymphoma, lymphomatoid granulomatosis, or other type of malignancy that mimics vasculitis o Cryoglobulinemic vasculitis
* Systemic lupus erythematosus
* Rheumatoid arthritis o Mixed connective tissue disease or any overlap autoimmune syndrome
* Known constitutive immunodeficiency
10. History of malignancy in the last 5 years (except adequately treated basal or squamous cell carcinoma of the skin)
11. Severe renal impairment (creatinine clearance \<30mL/min/1.73m2)
12. History of clinically significant liver disease or liver injury as indicated by abnormal liver function tests such as Aspartate Aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) or serum bilirubin. The investigator should be guided by the following criteria:
1. SGOT (AST) and SGPT (ALT) may not exceed 3 × the upper limit of normal (ULN). A single parameter elevated up to and including 3 × 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.
2. Alkaline phosphatase may not exceed 4 × ULN. An elevation up to and including 4 × 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.
3. Total bilirubin may not exceed 4 × ULN. If the total bilirubin concentration is increased above 4 × ULN, total bilirubin should be differentiated into the direct and indirect reacting bilirubin
13. Blood count abnormality:
1. Platelet count \< 50 x 10.3/mm3
2. Neutropenia \< 1000/mm3
3. Haemoglobin \< 8 g/dl
