Multicenter StudyPrognostic value of variables derived from the six-minute walk test in patients with COPD: Results from the ECLIPSE study.
In addition to the six-min walk distance (6 MWD), other six-min walk test (6 MWT) derived variables, such as mean walk-speed (6MWSpeed), 6-min walk-work (6 MWW), distance-saturation product (DSP), exercise-induced oxygen desaturation (EID), and unintended stops may be useful for the prediction of mortality and hospitalization in patients with chronic obstructive pulmonary disease (COPD). We studied the association between 6 MWT-derived variables and mortality as well as hospitalization in COPD patients and compared it with the BODE index. A three-year prospective study (ECLIPSE) to evaluate the prognostic value of 6 MWT-derived variables in 2010 COPD patients. ⋯ An adjusted Cox's regression model of hazard ratio [HR] for impaired 6 MWT-derived variables was significant referring to: mortality (6 MWD ≤334 m [2.30], 6MWSpeed ≤0.9 m/sec [2.15], 6 MWW ≤20000 m kg [2.17], DSP ≤290 m% [2.70], EID ≤88% [1.75], unintended stops [1.99]; and hospitalization (6 MWW ≤27000 m kg [1.23], EID ≤88% [1.25], BODE index ≥3 points [1.40]; all p ≤ 0.05). The 6 MWT-derived variables have an additional predictive value of mortality in patients with COPD. The 6 MWW, EID and the BODE index refine the prognosis of hospitalization.

Randomized Controlled Trial Multicenter StudyEfficacy and safety of umeclidinium added to fluticasone furoate/vilanterol in chronic obstructive pulmonary disease: Results of two randomized studies.
The aim of these studies (NCT01957163; NCT02119286) was to evaluate the efficacy and safety of umeclidinium (UMEC 62.5 μg and 125 μg) added to fluticasone furoate/vilanterol (FF/VI, 100/25 μg) in chronic obstructive pulmonary disease (COPD). ⋯ The results from these two studies demonstrate that the addition of umeclidinium (62.5 μg and 125 μg) to FF/VI (100/25 μg) provides statistically significant and clinically meaningful improvements in lung function compared with placebo + FF/VI in patients with COPD. Statistically significant improvements in quality of life with UMEC + FF/VI versus placebo + FF/VI were reported in one study only. Safety profiles were consistent across all treatment groups in both studies. These studies support the use of triple therapy in COPD, providing physicians with an alternative treatment option.
