T1  - The impact of indacaterol/glycopyrronium fixed-dose combination versus tiotropium monotherapy on lung function and treatment preference : a randomized crossover study – the FAVOR study
T2  - The International journal of chronic obstructive pulmonary disease
N2  - Background: The objective of the FAVOR study was to evaluate the effect of indacaterol/glycopyrronium (IND/GLY) versus tiotropium on peak forced expiratory volume in 1 s (FEV1) and also to investigate patient satisfaction and treatment preference.
Methods: Patients with moderate-to-severe airflow limitation (FEV1/forced vital capacity ratio of <0.70), those with a COPD assessment test score of ≥10, and those who were maintained on tiotropium HandiHaler® therapy prior to enrollment were recruited for the study, and randomized (1:1) to receive either 4 weeks open-label IND/GLY (110/50 µg) once daily followed by 4 weeks of tiotropium (18 µg) once daily or vice versa. The primary endpoint was FEV1 1 h post-inhalation after 4 weeks of treatment. Other endpoints included patient’s and physician’s preference for treatment, patient’s satisfaction evaluated using a study-specific questionnaire and the abbreviated Treatment Satisfaction Questionnaire for Medication, and safety and tolerability.
Results: Eighty-seven out of 88 randomized patients completed the study and showed significantly higher FEV1 1 h post-inhalation after 4 weeks of treatment with IND/GLY versus tiotropium (treatment difference =0.081 L; p=0.0017). IND/GLY was preferred over tiotropium among the patients (69.4% versus 30.6%, p=0.0004) and the physicians (81.6% versus 18.4%, p<0.0001). A higher proportion of the patients stated they were very satisfied or satisfied with IND/GLY versus tiotropium with regard to dyspnea reduction (79.3% versus 58.0%, respectively) and reduction of dyspnea on exertion (72.4% versus 43.2%, respectively). Patients treated with IND/GLY showed significant improvement in Treatment Satisfaction Questionnaire for Medication domain scores versus tiotropium. IND/GLY demonstrated a good safety and tolerability profile.
Conclusion: This study indicated that, beyond FEV1, important patient-reported outcomes improved with the open-label dual bronchodilator IND/GLY when compared with tiotropium. This study suggests that individual patients felt the lung function benefits with IND/GLY compared with tiotropium, which, in turn, may also have contributed to the preference for IND/GLY.
