Study of Fluticasone/Formoterol/Glycopyrronium for the Treatment Chronic Obstructive Pulmonary Disease (TRIPLAR)

Several studies have demonstrated the benefits of the LAMA (Long-Acting Muscarinic Antagonists) + LABA (Long-Acting Beta-Agonists) + IC (inhaled corticosteroids) combination in the treatment of chronic obstructive pulmonary disease (COPD). The use of the triple combination in patients with severe airflow obstruction and a history of flares has been associated with improved lung function, improved patient-reported endpoints and prevention of flares, when compared to LABA, LABA + LAMA and LABA + IC. Furthermore, when compared to dual therapies LABA + IC and LABA + LAMA, triple therapy has been able to reduce all-cause deaths among chronic obstructive pulmonary disease (COPD) patients.

Previously published studies have demonstrated that the triple combination of Fluticasone 250 mcg/Formoterol 12 mcg/Glycopyrronium 12.5 mcg was able to improve lung function in chronic obstructive pulmonary disease (COPD) patients with a history of flares. There was also a significant improvement in the mMRC (modified-Medical Research Council) which began in the 2nd week of treatment and continued up to week 12. The association was considered safe and well tolerated, with only mild to moderate adverse events recorded in approximately 25% of the subjects treated in the study.

Furthermore, bioavailability studies performed with the components of the combination proposed as experimental drug - Fluticasone/Formoterol/Glycopyrronium - indicated that there is no pharmacokinetic interaction between the 3 active ingredients when they were administered concomitantly to healthy individuals under fasting conditions.
