Comparison of glycopyrronium versus tiotropium on the time to clinically important deteriorations in patients with COPD: a post-hoc analysis of randomized trials.
Ontology highlight
ABSTRACT: Glycopyrronium is a once-daily, inhaled long-acting muscarinic antagonist (LAMA) demonstrating similar efficacy to inhaled tiotropium in patients with moderate-to-severe COPD; however, the benefit of LAMAs on COPD symptoms has been variable. COPD is a progressive disease in which many patients develop an acute or sustained deterioration. Data on the prevention of clinically important deteriorations (CID) using LAMAs are limited. A pooled analysis was performed on four Phase III trials (n?=?2936) that compared the efficacy of glycopyrronium (n?=?1859) with tiotropium (n?=?1077). The primary endpoint was significant delay and/or reduction in the occurrence of CID. CID was defined as any of the following: ?100?mL decrease from baseline in pre-dose forced expiratory volume in 1?second (FEV1), ?4 point increase in St George's Respiratory Questionnaire score or a moderate-to-severe COPD exacerbation occurring after the first dose of study medication. A sustained CID was a CID occurring on ?2 consecutive visits 4 weeks apart or for ?50% of all available subsequent visits. Baseline characteristics for the overall population were similar. Patients had moderate (62%) or severe (38%) COPD. Mean post-bronchodilator FEV1 was approximately 55% predicted, and mean FEV1 reversibility was 16.7 and 18.6% in the glycopyrronium and tiotropium groups, respectively. Both glycopyrronium and tiotropium significantly reduced time to CID and sustained CID versus placebo (p?
