Predicting response to benralizumab in patients with COPD: a plain language summary of publication of the GALATHEA and TERRANOVA studies.

What is this summary about?● This is a plain language summary of two articles originally published in The New England Journal of Medicine and The Lancet Respiratory Medicine. These articles presented the results of GALATHEA and TERRANOVA, two clinical studies that took place across 41 countries. ○ GALATHEA and TERRANOVA measured how patients' COPD changed from before their first benralizumab (10, 30, or 100 mg) injection, to after 56 weeks of treatment. ○ In both studies, benralizumab was compared with placebo. ○ To see whether benralizumab treatment would benefit any particular patients included in these studies, researchers carried out an additional analysis following the main studies of GALATHEA and TERRANOVA.
