Patients with severe COPD may benefit more from therapy that combines salmeterol and fluticasone [SFC] than treatment with tiotropium, according to results from a long-term, multi-center study, Investigating New Standards for Prophylaxis in Reducing Exacerbations (INSPIRE) that directly compared the two therapies.
Although we found no difference in the overall rate of exacerbations between treatment groups, SFC treatment was associated with better health status, fewer patient withdrawals, and a lower mortality rate than occurred during tiotropium therapy, said lead author if the study, Jadwiga Wedzicha, M.D., of the Royal Free & University College Medical School in London
This was the first large-scale trial to directly compare the two different treatment approaches. The results appeared in the first issue for January of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.
The researchers recruited 1,323 patients with severe COPD and randomized them to receive one of two treatmentseither SFC or tiotropiumfor two years. They analyzed number and type of exacerbations, health status as measured by the St. Georges Respiratory Questionnaire (SGRQ), lung function (post-dose forced expiratory volume in one second) and study withdrawal rate. The study was double-blinded and double-dummy controlled, and all patients underwent identical intensification of treatment before beginning the trial to standardize their clinical conditions.
While exacerbation rates between the two treatment groups were statistically indistinguishable, there were differences in the treatment that the exacerbations required. Oral corticosteroids were used more often to treat the tiotropium group, whereas patients on SFC required antibiotics more frequently.
This finding provides indirect evidence that these treatments affect apparently similar patients in different ways that affect clinical judgmen
