E.1.1.1 | Medical condition in easily understood language |
Giant Cell Arteritis (GCA) is a condition in which there is inflammation of the large arteries, predominately those in the head and neck. Symptoms include headache, scalp/jaw pain and vision problems |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary purpose of this study is to determine whether delayed release prednisone, in doses equivalent to standard of care immediate release prednisolone, can effectively maintain disease control in new cases of giant cell arteritis. |
|
E.2.2 | Secondary objectives of the trial |
Flare free patients in each arm at 26 weeks Time to the first flare Time to second flare Total steroid dosage Patient global assessment of disease activity (overall effect of the condition on patient) Reduction in levels of inflammation on blood tests (ESR and CRP) Improvement in assessment of disability and quality of life (HAQ and Euro QOL 5D) Visual Function Questionnaire (VFQ-25) in patients with vision loss (quality of life effect from vision loss) Improvement in sleep and fatigue Proportion with steroid related side effects in each arm with particular reference to Weight gain, fluid retention, bruising, blood sugar tolerance, raised blood pressure, indigestion |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Age ≥50 years New diagnosis of GCA within last 4 weeks ESR >30 mm/h or CRP >10 mg/dl Unequivocal clinical and laboratory picture of GCA either fulfilling American College of Rheumatology criteria or typical features (as assessed by clinician) including one or several of the following: - New onset localised pain in the head after 50 years of age - Jaw or tongue claudication - Visual symptoms (amaurosis fugax, blurring and diplopia) - Systemic symptoms not attributable to other causes - Limb claudication - Polymyalgia - Abnormal temporal artery (tender, thickened, beading, decreased pulsation) - Scalp tenderness - Decreased visual acuity/visual field defect - Anterior ischemic optic neuropathy (AION) or central retinal artery occlusion on fundoscopy - Upper cranial nerve palsies - Typical ischaemic complications of GCA (eg AION) |
|
E.4 | Principal exclusion criteria |
GCA on steroid therapy longer than 4 weeks Previous exposure to DMARD/biologic therapy Serious or chronic infection in the last 3 months. Diagnostic doubt Failure to respond to high dose steroids within 5 days Known other vasculitis Patients with evolving ischemic symptoms requiring IV methylprednisolone Malignancy Patients unable to consent |
|

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
26 weeks after the patient has been started on steroids |
|
E.5.2 | Secondary end point(s) |
Relapse free subjects in each arm at 26 weeks Time to the first flare Time to second flare Cumulative steroid dosage Patient global VAS of disease activity Reduction of ESR Reduction of CRP Improvement in HAQ and Euro QOL 5D Visual Function Questionnaire (VFQ-25) in patients with vision loss. Improvement in sleep and fatigue scores Proportion with steroid related toxicity in each arm with particular reference to weight gain, fluid retention, bruising, glucose tolerance, hypertension, dyspepsia |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
