A Study of Ustekinumab in Participants With Takayasu Arteritis (TAK)
Takayasu Arteritis
About this trial
This is an interventional treatment trial for Takayasu Arteritis
Eligibility Criteria
Inclusion Criteria:
- Must have developed a relapse of Takayasu Arteritis (TAK) within 12 weeks prior to administration of study intervention and the relapse must have occurred at a dose of at least 7.5 milligrams (mg)/day (prednisolone or equivalent)
- Must be receiving oral glucorticoid (GC) treatment of greater than or equal to (>=)15 mg/day (prednisolone or equivalent), inclusive for the treatment of relapsing TAK and be on a stable dose for at least 2 weeks prior to the first administration of study intervention
- If receiving an oral anti-platelet therapy (including but not limited to aspirin, clopidogrel, ticlopidine) or anti-coagulation therapy (including but not limited to warfarin) for treatment of TAK, the dose must have been stable for at least 2 weeks prior to first administration of the study intervention. In terms of warfarin, the dose should be controlled 1-5mg/day to maintain Prothrombin Time and International Normalized Ratio (PT-INR) target range between 2.0-3.0 (if participants are over 70 years old, PT-INR target range should be between 1.6-2.6)
- Have no history of latent or active Tuberculosis (TB) prior to screening. An exception is made for participants who have a history of latent TB and are currently receiving treatment for latent TB, will initiate treatment for latent TB at least 3 weeks prior to the first administration of the study intervention, or have documentation of having completed appropriate treatment for latent TB within 3 years prior to the first administration of the study intervention. It is the responsibility of the investigator to verify the adequacy of previous antituberculous treatment and provide appropriate documentation
- If receiving an oral anti-hypertensive therapy for treatment of TAK, the dose must have been stable for at least 2 weeks prior to first administration of the study intervention
Exclusion Criteria:
- Has currently any known severe or uncontrolled TAK complications (example, hypertension not responding to adequate treatment, aortic incompetence with cardiac insufficiency, progressing aortic aneurysm, coronary artery lesions with severe stenosis)
- Has received immunosuppressant (s) (including but not limited to Methotrexate [MTX], Azathioprine [AZA], Mycophenolate Mofetil [MMF], oral Triamcinolone [TAC], oral Cyclosporine A) within 4 weeks of first study intervention
- Has had a Bacille Calmette-guerin (BCG) vaccination within 12 months of screening
- Any major illness/condition or evidence of an unstable clinical condition example, history of liver or renal insufficiency (estimated creatinine clearance below 60 milliliters/minute [mL/min]); significant (cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurologic, hematologic, rheumatologic, psychiatric, or metabolic disturbances), disease of any organ system or active acute or chronic infection/infectious illness that, in the investigator's judgment, will substantially increase the risk to the participant if he or she participates in the study
- Having a condition that is steroid dependent (example, steroid dependent asthma, chronic obstructive pulmonary disease, et cetera) that is not amenable to tapering oral GC

Arms of the Study
Arm 1
Arm 2
Experimental
Placebo Comparator
Ustekinumab
Placebo
Double-blind (DB) Period: Participants will receive weight-ranged based ustekinumab (6 milligrams/kilogram[mg/kg]) as IV infusion at Week 0 followed by ustekinumab 90mg injection SC 8 weeks after initial IV dose, then every 8 weeks (q8w) thereafter until the end of the DB period with starting the protocol defined oral GC taper regimen from Week 2 visit. Open Label Extension (OLE) period: Participants will receive ustekinumab SC injection at Week OL-0, followed by ustekinumab 90mg SC injection with oral GC taper at investigator's discretion for 52 weeks (Week OL-52) or until 32 weeks from first SC administration after end of DB period whichever is later. Long-term Extension (LTE) Period: Participants who completed OLE period may be eligible to enter LTE and continue to receive ustekinumab 90mg SC injection q8w.
DB period: Participants will receive placebo intravenous (IV) infusion at Week 0 followed by placebo subcutaneous (SC) injection administration, 8 weeks after the initial IV dose, then q8w thereafter until the end of DB period with starting the protocol defined oral GC taper regimen from Week 2 visit. OLE period: Participants will receive ustekinumab SC at Week OL-0, followed by SC administration of ustekinumab with oral GC taper at investigator's discretion for 52 weeks (Week OL-52) or until 32 weeks from the first SC administration after the end of DB period, whichever is later. LTE Period: Participants who complete their participation in OLE period may be eligible to enter the LTE and continue to receive 90 mg SC ustekinumab q8w.
