A Study to Evaluate Guselkumab for the Treatment of Participants With New-onset or Relapsing Giant Cell Arteritis (THEIA)
Giant Cell Arteritis
About this trial
This is an interventional treatment trial for Giant Cell Arteritis
Eligibility Criteria
Inclusion criteria
- Diagnosis of Giant cell arteritis (GCA) according to the revised American College of Rheumatology criteria
- GCA diagnosis confirmed by either temporal artery biopsy revealing features of GCA either at time of diagnosis or at other timepoint during disease history; or evidence of cranial GCA either at time of diagnosis or at other timepoint during disease history by cranial doppler-ultrasound; or cranial Magnetic Resonance Imaging (MRI) or Magnetic Resonance Angiography; or other imaging modality upon agreement with the sponsor or evidence of GCA by angiography or cross-sectional imaging (ultrasound, MRI, computed tomography [CT], positron emission tomography [PET])
- Have new onset or relapsing GCA
- Have active GCA within 6 weeks of first study intervention: Active GCA: presence of signs and symptoms of GCA and elevated erythrocyte sedimentation rate (ESR) greater than or equal to (>=) 30 millimeter per hour (mm/hour), or C-reactive protein (CRP) >= 10 milligrams per liter (mg/L) (or 1 milligrams per deciliter [mg/dL]), attributed to active GCA. ESR >= 30 mm/hour or CRP >= 10 mg/L (or 1 mg/dL) is not required if active GCA has been confirmed by a positive temporal artery biopsy or ultrasound or other imaging modality within 6 weeks of first study intervention
- Clinically stable GCA disease on a glucocorticoid (GC) dose between 20 and 60 milligrams per day (mg/day) (prednisone or equivalent) at randomization such that the participant is able to safely participate in the protocol defined prednisone taper regimen, in the opinion of the investigator
Exclusion criteria
- Has any known severe or uncontrolled GCA complications
- Has any rheumatic disease other than GCA such that could interfere with assessment of GCA
- Has a current diagnosis or signs or symptoms of severe, progressive, or concomitant medical condition that places the participant at risk by participating in this study)
- Has or has had any major ischemic event, within 12 weeks of first study intervention. Has a personal history of arterial thrombosis or venous thromboembolism (including deep venous thrombosis [DVT] and Pulmonary Embolism [PE])
- Has any comorbidities requiring 3 or more courses of systemic GCs within 12 months of first study intervention, AND, inability, in the opinion of the investigator, to withdraw GC therapy through protocol-defined taper regimen due to suspected or established adrenal insufficiency, OR, currently on systemic chronic GC therapy for reasons other than GCA and be GC dependent and have the potential to flare due to GC tapering (e.g. unstable asthma, unstable COPD)
- Has a history of, or ongoing, chronic or recurrent infectious disease
- Has received within specified timeframe, or 5 half-lives (whichever is greater) , or has failed treatment with any investigational or approved biologic agents or Janus Kinase Inhibitor prior to first study intervention
- Use of any of the following systemic immunosuppressant treatments within the specified timeframe prior to study start: Any cytotoxic agents (cyclophosphamide, chlorambucil, nitrogen mustard, or other alkylating agents) with 6 months; Hydroxychloroquine, cyclosporine A, azathioprine, tacrolimus, sirolimus, sulfasalazine, leflunomide with cholestyramine washout or mycophenolate mofetil/mycophenolic acid within 3 months; Intramuscular, intra-articular, intrabursal, epidural, intra-lesional or IV GCs within 6 week; and Methotrexate (MTX) within 12 weeks. If started MTX >12 weeks prior to first study intervention MTX must have been at a stable dose for minimally 4 weeks and must not be receiving more than 25 mg oral or SC MTX per week
- Has chronic continuous use of systemic GCs for greater than (>) 4 years or inability, in the opinion of the investigator, to withdraw GC treatment through protocol-defined taper regimen due to suspected or established adrenal insufficiency

Guselkumab
Placebo
Participants will receive guselkumab subcutaneously (SC) every 4 weeks from Week 0 through Wweek 48. This will be in combination with a protocol specified 26-week GC taper. Participants of the long-term extension (LTE) period will continue to receive subcutaneous (SC) injections every 4 weeks starting at Week 52 (LTE Week 0) through Week 100 (LTE Week 48) or until the participants have a Giant cell arteritis (GCA) flare, or the participants discontinues treatment due to unblinding after the Week 60 DBL for the Main study, or until a decision is made not to continue clinical development in this GCA population, whichever occurs first.
