Official title

A Phase III, Multicenter, Randomized, Double-Blind Placebo-Controlled Study to Assess the Efficacy and Safety of Tocilizumab in Subjects With Giant Cell Arteritis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of tocilizumab in participants with GCA. The study will consist of 2 parts: a 52-week double-blind treatment period (Part 1) followed by a 104-week open label long-term follow-up period (Part 2). In Part 1 of the study eligible participants will be randomized to receive either tocilizumab every week (qw) or every 2 weeks (q2w) or placebo for 52 weeks, with tapering oral daily doses of prednisone. After Week 52, participants in remission will stop study treatment and enter long-term follow-up, whereas participants with disease activity or flares will receive open-label tocilizumab or other treatment at the discretion of the investigator for a maximum period of 104 weeks.
