Analysis of health-related quality of life (HR-QOL) data from the GiACTA trial, in which 251 patients with giant cell arteritis (GCA) were treated with either tocilizumab or placebo in addition to a tapered dose of prednisone, showed improvements in overall HR-QOL for patients treated with tocilizumab plus prednisone compared with those treated with placebo plus prednisone. Clinically meaningful differences were reported for 36-Item Short-Form Health Survey Mental Component Summary scores (P = 0.0012) and for Patient Global Assessment scores (P = 0.0029) in those receiving tocilizumab.
