Composite endpoints in COPD: clinically important deterioration in the UPLIFT trial

Klaus F Rabe et al. Respir Res. .

Abstract

Background: Assessments of lung function, exacerbations and health status are common measures of chronic obstructive pulmonary disease (COPD) progression and treatment response in clinical trials. We hypothesised that a composite endpoint could more holistically assess clinically important deterioration (CID) in a COPD clinical trial setting.

Methods: A composite endpoint was tested in a post hoc analysis of 5652 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2-4 COPD from the 4-year UPLIFT study. Patients received tiotropium 18 μg or placebo.

Results: The composite endpoint included time to first confirmed decrease in trough forced expiratory volume in 1 s (FEV1) ≥100 mL, confirmed increase in St. George's Respiratory Questionnaire (SGRQ) total score ≥ 4 units, or moderate/severe exacerbation. Most patients (> 80%) experienced CID, with similar incidence among GOLD subgroups. Most confirmed trough FEV1 (74.6-81.6%) and SGRQ (72.3-78.1%) deteriorations were sustained across the study and in all GOLD subgroups. Patients with CID more frequently experienced subsequent exacerbation (hazard ratio [HR] 1.79; 95% confidence interval [CI] 1.67, 1.92) or death (HR 1.21; 95% CI 1.06, 1.39) by Month 6. CID was responsive to bronchodilator treatment.

Conclusions: Composite endpoints provide additional information on COPD progression and treatment effects in clinical trials.

Kaplan–Meier estimates for the time to CID in the overall population and GOLD subgroups. Kaplan–Meier estimates of time to first event, two of three events, or three of three events of the components of the composite endpoint (trough FEV1 decline ≥100 mL, SGRQ score deterioration ≥4 units, or moderate/severe exacerbation) in (a) the overall population, (b) GOLD 2 patients, (c) GOLD 3 patients, and (d) GOLD 4 patients. - indicates either that this value could not be assessed (median was not estimable) or is not applicable (HR only displayed for time to event analysis). CI: confidence interval; FEV1: forced expiratory volume in 1 s; GOLD: Global Initiative for Chronic Obstructive Lung Disease; HR: hazard ratio; SGRQ: St. George’s Respiratory Questionnaire
