Abstract
Introduction
The 52-week long-term safety of once-daily indacaterol acetate/glycopyrronium bromide/mometasone furoate (IND/GLY/MF) high-dose (150/50/160 µg) and IND/MF high-dose (150/320 µg) was evaluated in two studies enrolling Japanese patients with inadequately controlled asthma.
Methods
Study 1 (IND/GLY/MF) and Study 2 (IND/MF) were 52-week, phase III, open-label, single-arm, multicenter studies conducted in Japanese adult patients with inadequately controlled asthma. The primary endpoint was incidence and severity of treatment-emergent adverse events (AEs) over 52-weeks.
Results
In Study 1, 94 patients received IND/GLY/MF high-dose and 84 (89.4%) patients completed the 52-week study treatment; in Study 2, 51 patients received IND/MF high-dose and 48 (94.1%) patients completed the 52-week study treatment. In Study 1, 68.1% and 6.4% of 94 patients reported ≥1 AE and ≥1 serious AE (SAE) respectively. In Study 2, 78.4% of 51 patients reported ≥1 AE; no patients reported SAEs. The most commonly reported AEs were asthma (exacerbation; 30.9% and 54.9%) and nasopharyngitis (18.1% and 29.4%) in Study 1 and Study 2, respectively. Severe AEs including asthma (exacerbation) were reported in 13.8% and 13.7% of patients in Study 1 and Study 2, respectively. In Study 1, 10 patients (10.6%) reported treatment-related AEs, of which dysphonia (9 patients [9.6%]) was the most commonly reported; no treatment-related AEs were reported in Study 2. In Study 1, one death (not study drug-related) was reported after study discontinuation (92 days after last dose of study medication).
Conclusions
Once-daily IND/GLY/MF and IND/MF high-dose were well-tolerated in Japanese patients with inadequately controlled asthma. No unexpected safety findings were observed.
