| E.2.1 | Main objective of the trial |
| The primary objective is to demonstrate that the efficacy of secukinumab 300 mg s.c. in combination with a 26-week Glucocorticoids (GC) taper regimen is superior to placebo in combination with a 52-week GC taper regimen in participants with GCA based on sustained remission at Week 52. |
|
| E.2.2 | Secondary objectives of the trial |
*All assessments made with secukinumab in combination with a 26-week GC taper regimen compared to placebo in combination with a 52-week GC taper regimen in participants with GCA
To demonstrate the superior efficacy of 300 mg based on:
- Time to clinical failure through Week 52
- Cumulative GC dose through Week 52
To demonstrate the superior efficacy of 150 mg based on:
- Sustained remission at Week 52
- Time to clinical failure through Week 52
- Cumulative GC dose through Week 52
To demonstrate the superior effect on participant's QoL of 300 or 150 mg:
- Based on change of SF-36 score (PCS) at Week 52
To demonstrate the superior effect of 300 or 150 mg based on change in Glucocorticoid Toxicity Index (GTI) at Week 52
To demonstrate the superior effect of 300 or 150 mg on participant's QoL in participants with GCA based on change in:
- FACIT-Fatigue score at Week 52
To evaluate the safety and tolerability of secukinumab |

| E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Optional MRI/MRA Imaging Sub-Study
To assess the efficacy of secukinumab in combination with a 26-week glucocorticoid (GC) taper regimen compared to placebo in combination with a 52 week GC taper regimen, based on improvement in signs of vascular inflammation in an optional Magnetic Resonance Imaging (MRI)/ Magnetic Resonance Angiography (MRA) substudy at Screening and Week 52 |
|
| E.3 | Principal inclusion criteria |
Patients eligible for inclusion in this study must meet all of the following
criteria:
- Signed informed consent must be obtained prior to participation in the
study.
- Patient must be able to understand and communicate with the
investigator and comply with the requirements of the study.
- Male or non-pregnant, non-lactating female patients at least 50 years
of age.
- Diagnosis of GCA based on meeting all of the following criteria:
- Age at onset of disease ≥ 50 years.
- Unequivocal cranial symptoms of GCA (new-onset localized
headache, scalp or temporal artery tenderness, permanent or temporary
ischemia-related vision loss, or otherwise unexplained mouth or jaw
pain upon mastication), and/or unequivocal symptoms of polymyalgia
rheumatica (PMR) (defined as shoulder and/or hip girdle pain associated
with inflammatory morning stiffness) and/or symptoms of limb ischemia
(claudication).
- Temporal artery biopsy (TAB) revealing features of GCA and/or
cross-sectional imaging study such as ultrasound (e.g. cranial or
axillary), MRI/MRA, CTA, or PET-CT with evidence of vasculitis.
- Active disease as defined by meeting both of the following within 6
weeks of Baseline:
- Presence of signs or symptoms attributed to active GCA and not
related to prior damage (e.g., visual field loss that occurred prior to 6
weeks before Baseline without worsening occurring within 6 weeks of
baseline)
- Elevated erythrocyte sedimentation rate (ESR) ≥ 30 mm/hr or Creactive
protein (CRP) ≥ 10 mg/L attributed to active GCA or active GCA
on TAB or on imaging study
- Participants to meet definition of new-onset GCA or relapsing GCA:
- Definition of new-onset GCA: GCA diagnosis within 6 weeks of
Baseline visit
- Definition relapsing GCA: GCA diagnosed > 6 weeks before
Baseline visit and following institution of an appropriate treatment
course for GCA, participant has experienced recurrence of active
symptoms or signs of disease after resolution.
*The 6-week timeframe is to be calculated from the date of suspected
GCA diagnosis. Suspected diagnosis is defined as the date when GC
therapy was initiated.
- Patients' current GCA episode should be treatable with a dose of
prednisone (or equivalent) designed to adequately achieve disease
control in accordance with international guidelines. If this is not
possible due to concerns regarding GC toxicity, the patient should not be
enrolled. It must be medically appropriate for the patient to receive
prednisone (or equivalent) 20 mg-60 mg daily (or equivalent) at BSL .
- Patients taking MTX (≤ 25 mg/week) are allowed to continue their
medication provided they have taken it for at least 2 months, are on a
stable dose for at least 4 weeks prior to randomization. |
