Summary
Study start date: November 5, 2020
Actual date on which the first participant was enrolled.Treatment of giant cell arteritis (GCA) relies on the use of glucocorticoids (GC), with a very good clinical response at treatment initiation. However, relapses at GC tapering are frequent. GCA population is elderly, frequently over 80 years, and is especially affected by GC-related side effects, that increase proportionally with treatment duration. Thus, metabolic, musculo-skeletal, infectious or neuro-psychiatric complications are frequent during prolonged GC use. After GC introduction, gradual tapering is scheduled, provided the disease remains clinically and biologically controlled. In France, guidelines recommend tapering GC on an 18-24 months timeframe, while other countries, such as the USA, usually taper GC over a shorter period, often 6-8 months. Few comparative data exist on the relapse rates or the GC-related side effects in both settings. In this prospective multicenter study, two GC-tapering schedules are planned: patients in one arm (short treatment) will be treated for 28 weeks, while patients in the second arm will be treated for 52 weeks. Each starting dose of GC and tapering doses will be adapted to body weight. The primary endpoint is to compare the remission rate without relapse at W52 between the two groups and the secondary endpoints are: 1) cumulative GC doses at W52; 2) GC-related side effects and 3) number of relapses (minor and severe) in both arms at W52. The results of this study might considerably modify future French clinical practice if investigators confirm that a shorter GC treatment does not significantly impact the disease course while reducing GC-related side effects.
