| Primary | Percentage of Participants Who Achieved Sustained Disease Remission at Week 52 | At Week 52 | Disease remission was defined as resolution of signs and symptoms of giant cell arteries (GCA), and normalization of C-reactive protein (CRP) (\<10 mg/L). Sustained remission was defined as meeting all of the following parameters: achievement of disease remission not later than Week 12, absence of disease flare (defined as recurrence of signs and symptoms attributable to active GCA plus an increase in corticosteroid \[CS\] dose due to GCA or elevation of erythrocyte sedimentation rate \[ESR\] attributable to active GCA plus an increase in CS dose due to GCA) from Week 12 through Week 52, normalization of CRP (to \<10 mg/L, with absence of successive elevations to \>=10 mg/L) from Week 12 through Week 52, and successful adherence to prednisone taper from Week 12 through Week 52. |
| Primary | Percentage of Participants Who Achieved Sustained Disease Remission at Week 24 | At Week 24 | Disease remission was defined as resolution of signs and symptoms of GCA, and normalization of CRP \<10 mg/L. Sustained remission was defined as meeting all of the following parameters: achievement of disease remission not later than Week 12, absence of disease flare (defined as recurrence of signs and symptoms attributable to active GCA plus an increase in CS dose due to GCA, or elevation of ESR attributable to active GCA plus an increase in CS dose due to GCA) from Week 12 through Week 24, normalization of CRP (to \<10 mg/L, with an absence of successive elevations to \>=10 mg/L) from Week 12 through Week 24, and successful adherence to the prednisone taper from Week 12 through Week 24. |
| Secondary | Number of Participants With Achievement of Disease Remission up to Week 12: Week 52 Analysis Set | Up to Week 12 | Disease remission was defined as resolution of signs and symptoms of GCA, and normalization of CRP (\< 10 mg/L). The status of normalization of CRP (\<10 mg/L) was determined based on the last two non-missing post-baseline CRP values measured up to Week 12. If at least one of the value was \<10 mg/L, then it was considered as normalization of CRP. Participants who took rescue corticosteroid (CS) due to active GCA prior to Week 12 or who permanently withdrew from the study treatment prior to Week 12 were considered as not achieved disease remission by Week 12. |
| Secondary | Number of Participants With Achievement of Disease Remission up to Week 12: Intent-to-treat (ITT) Population | Up to Week 12 | Disease remission was defined as resolution of signs and symptoms of GCA, and normalization of CRP (\< 10 mg/L). The status of normalization of CRP (\<10 mg/L) was determined based on the last two non-missing post-baseline CRP values measured up to Week 12. If at least one of the value was \<10 mg/L, then it was considered as normalization of CRP. Participants who took rescue CS due to active GCA prior to Week 12 or who permanently withdrew from the study treatment prior to Week 12 were considered as not achieved disease remission by Week 12. |
| Secondary | Number of Participants With Absence of Disease Flare From Week 12 Through Week 52: Week 52 Analysis Set | From Week 12 through Week 52 | Disease flare was defined as either recurrence of signs and symptoms attributable to active GCA plus an increase in CS dose due to GCA, or elevation of ESR attributable to active GCA plus an increase in CS dose due to GCA. Number of participants with absence of disease flare from Week 12 through Week 52 were reported. |
| Secondary | Number of Participants With Absence of Disease Flare From Week 12 Through Week 24: ITT Population | From Week 12 through Week 24 | Disease flare was defined as either recurrence of signs and symptoms attributable to active GCA plus an increase in CS dose due to GCA, or elevation of ESR attributable to active GCA plus an increase in CS dose due to GCA. Number of participants with absence of disease flare from Week 12 through Week 24 were reported. |
| Secondary | Number of Participants With Normalization of C-Reactive Protein From Week 12 Through Week 52: Week 52 Analysis Set | From Week 12 through Week 52 | Normalization of CRP was defined as CRP levels \<10 mg/L. If there were two or more consecutive visits with CRP \>=10 mg/L, then it was categorized as no normalization of CRP. |
| Secondary | Number of Participants With Normalization of C-Reactive Protein (CRP) From Week 12 Through Week 24: ITT Population | From Week 12 through Week 24 | Normalization of CRP was defined as CRP levels \<10 mg/L. If there were two or more consecutive visits with CRP \>=10 mg/L, then it was categorized as no normalization of CRP. |
| Secondary | Number of Participants With Successful Adherence to the Prednisone Taper From Week 12 Through Week 52: Week 52 Analysis Set | From Week 12 through Week 52 | Successful adherence to the prednisone taper from Week 12 through Week 52 was defined as participants who did not take rescue therapy from Week 12 through Week 52 and might include the use of any excess prednisone (beyond the per protocol CS tapering regimen) with a cumulative dose of \<=100 mg (or equivalent), such as those employed to manage adverse event (AE) not related to GCA. |
| Secondary | Number of Participants With Successful Adherence to the Prednisone Taper From Week 12 Through Week 24: ITT Population | From Week 12 through Week 24 | Successful adherence to the prednisone taper from Week 12 through Week 24 was defined as participants who did not take rescue therapy from Week 12 through Week 24 and might include the use of any excess prednisone (beyond the per protocol CS tapering regimen) with a cumulative dose of \<=100 mg (or equivalent), such as those employed to manage AE not related to GCA. |
| Secondary | Total Cumulative Corticosteroid (Including Prednisone) Dose | Up to Week 52 | Cumulative dose of CS used for GCA disease was defined as the dose taken up to the end of treatment, including expected prednisone in tapering regimen per protocol, CS used in rescue therapy and the use of commercial prednisone (an excess of \<=100 mg of prednisone during the study treatment period employed to manage AE not related to GCA). The total cumulative CS dose was based on the total number of days with complete or partial intake, no imputation was done on missed tablets. |
| Secondary | Time to First Giant Cell Arteritis Disease Flare | Up to Week 52 | Time to first GCA flare was defined as the duration (in days) from randomization to first GCA flare after clinical remission (defined as resolution of signs and symptoms and normalization of CRP \[\<10 mg/L\]) and up to 52 weeks. Disease flare was defined as either the recurrence of signs or symptoms attributable to active plus an increase in CS dose due to GCA or elevation of ESR attributable to active GCA plus an increase in CS dose due to GCA. Kaplan-Meier method was used for the analysis. Participants who never achieved remission were censored at randomization day; and those who achieved clinical remission and never flared were censored at the end of treatment assessment date up to Week 52. |
| Secondary | Composite Glucocorticoid Toxicity Index (C-GTI): Cumulative Worsening Score (CWS) and Aggregate Improvement Score (AIS) at Week 24: ITT Population | At Week 24 | GTI assessed glucocorticoid (GC) related morbidity and GC-sparing ability of other therapies; composed of 2 components: Composite GTI and Specific List. Composite GTI contained 9 domains and Specific List contained of 23 items (11 domains), used as complementary tool to C-GTI. Composite GTI score was the sum of 9 domain-specific scores at each visit and Cumulative GTI score was the sum of composite GTI scores across each visit. Two cumulative GTI scores: CWS and AIS at Week 24 are reported in this outcome measure (OM). CWS assessed cumulative GC toxicity regardless of whether toxicity had lasting effects or was transient. AIS assessed new therapy effectiveness in decreasing any Baseline GC toxicity over time. For CWS, composite score ranged from 0 to 439 and for AIS, composite score ranged from -346 to 439. For both CWS and AIS, the minimum score implies the least toxicity and the maximum score implies the most toxicity. |
