Details and patient eligibility

About

The purpose of this study is to evaluate the efficacy of ustekinumab compared to placebo, in combination with oral glucocorticoid (GC) taper regimen, in participants with relapsing Takayasu Arteritis (TAK).

Enrollment: 14 patients

Sex: All

Ages: 15 to 75 years old

Volunteers: No Healthy Volunteers

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

Trial design

Masking: Double Blind

---

14 participants in 2 patient groups, including a placebo group

Ustekinumab

Experimental group

Description:

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.

Treatment:

Drug: Ustekinumab

Drug: Glucorticoid Taper Regimen

Placebo

Placebo Comparator group

Description:

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.

Treatment:

Drug: Ustekinumab

Drug: Glucorticoid Taper Regimen

Other: Placebo
