A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Efficacy of Upadacitinib in Subjects With Giant Cell Arteritis: SELECT-GCA
In Brief
A Phase 3 clinical trial evaluating Upadacitinib, Corticosteroid (CS), and 1 other intervention for Giant Cell Arteritis (GCA). Completed, enrolled 429 participants across 172 sites in 24 countries.
Detailed Summary
This study consists of two periods. The objective of Period 1 is to evaluate the efficacy of upadacitinib in combination with a 26-week corticosteroid (CS) taper regimen compared to placebo in combination with a 52-week CS taper regimen, as measured by the proportion of participants in sustained remission at Week 52, and to assess the safety and tolerability of upadacitinib in participants with giant cell arteritis (GCA). The objective of Period 2 is to evaluate the safety and efficacy of continuing versus withdrawing upadacitinib in maintaining remission in participants who achieved sustained remission in Period 1.

Interventions
Administered orally once a day
At Baseline, all participants switched to corticosteroids (CS) provided by the sponsor with the oral prednisone or prednisolone dose at 20, 30, 40, 50, or 60 mg QD. The initial dose of prednisone or prednisolone was at the discretion of the investigator, based on disease severity and comorbid medical conditions, at a minimum of 20 mg QD at Baseline. At Baseline, if a participant was on a dose other than 20, 30, 40, 50, or 60 mg QD, the dose was rounded up or down, as clinically indicated per investigator discretion, to the nearest of these doses. Prednisone or prednisolone was tapered according to a predefined schedule over a 26- or 52-week period. Open-label prednisone or prednisolone was provided until the dose was tapered to 20 mg/day. Subsequently, blinded prednisone or prednisolone was provided for the remaining blinded taper regimen through Week 52.
