A total of 1306 patients with IPF were randomized (525 patients at 106 sites in ISABELA 1 and 781 patients at 121 sites in ISABELA 2). Enrollment began in November 2018 in both trials and follow-up was completed early due to study termination on April 12, 2021, for ISABELA 1 and on March 30, 2021, for ISABELA 2.InterventionsPatients were randomized 1:1:1 to receive 600 mg of oral ziritaxestat, 200 mg of ziritaxestat, or placebo once daily in addition to local standard of care (pirfenidone, nintedanib, or neither) for at least 52 w...

However, the relationship between the level of asthma control and increasing doses of Cic is unknown. This study investigated whether long-term treatment with higher doses of Cic would further improve asthma symptoms in patients with uncontrolled asthma despite ICS use. In a double-blind, randomized, parallel-group study, 367 patients were allocated to one of three treatment arms (Cic 160, 320 and 640 µg/day). After a single-blind, 3-week baseline period with Cic 160 µg/day, eligible patients were randomized to receive 52 weeks of treatment with Cic 160, 320 or 640 µg/day (double-blind period) during which forced expiratory volume in 1 second (FEV1), exacerbations and Asthma Control Questionnaire (ACQ) scores were measured. Treatment with all the three doses was associated with significant improvements in ACQ scores, FEV1 and asthma symptoms ...

COPD poses a high economic burden with the total expenditure per patient costing 40% and nearly one-third of an average family income in urban and rural areas of China, respectively. Despite the use of the Global Initiative for Chronic Obstructive Lung Disease strategy document being recommended for the diagnosis and management of COPD, the majority of patients with COPD go undiagnosed or are not managed appropriately by physicians. Long-acting β2-agonists (LABAs) have long been used for symptomatic management of COPD, with salmeterol and formoterol being the commonly used twice-daily treatments. Indacaterol is the first once-daily LABA, approved at a dose of 150 µg once daily in China. Several phase III studies have shown that indacaterol 150 µg improves lung function, breathless...

Data from a 12-week, double-blind, placebo-controlled, parallel-group study in patients randomized to indacaterol 150 μg, indacaterol 300 μg or placebo once daily were analyzed based on baseline disease severity (moderate or severe). Endpoints were: trough FEV(1) (average of 23 h 10 min and 23 h 45 min post-dose values), transition dyspnoea index (TDI) and St George's Respiratory Questionnaire (SGRQ) at Week 12. Safety data were collected. Of 347 patients randomized, 59.7% had moderate, and 40.3% had severe COPD. Least squares means (LSMs) indacaterol-placebo differences in trough FEV(1) at Week 12 exceeded the pre-specified minimal clinically important difference (MCID) of 0.12L and were statistically superior ...

This study was primarily designed to obtain the regulatory approval of indacaterol in Japan. Moderate-to-severe COPD patients were randomized to indacaterol 150 µg, indacaterol 300 µg or placebo once daily. Efficacy variables: trough FEV(1) (average of 23 h 10 min and 23 h 45 min post-dose values), health status (St. George's Respiratory Questionnaire) and transition dyspnoea index at week 12. Safety/tolerability was evaluated. A total of 347 patients were randomized (96.5% male, mean (SD) age 66.7 (8.38) years, post-bronchodilator FEV(1) % predicted: 53.7 (12.50)); 88.8% completed. The least squares means (LSM) trough FEV(1) at week 12 for indacaterol 150 µg, indacaterol 300 µg and placebo were 1.34 L, 1.37 L and 1.17 L, respectively, with differences versus placebo exceeding the prespecified minimal clinically important difference of 0.12 L (0.17 L and 0.20 L for indacaterol 150 µg and 300 µg, respectively, both P < 0.001). The week 12 LSM transition dyspnoea index score was statistically superior for both indacaterol doses versus placebo (differences of 1.30 and 1.26, P < 0.001; both exceeding the minimal clinically important difference of 1). At week 12, both indacaterol doses provided statistically significant (P ≤ 0.005) and clinically meaningful (≥4 units) improvements in LSM St. George's Respiratory Questionnaire total score versus placebo (differences: -4.8 and -5.7 units). Adverse events for indacaterol (49.1%, both doses) were lower than placebo (59.0%) and were mostly mild/moderate in severity; no deaths were reported. Indacaterol provided clinically significant bronchodilation and improvements in dyspnoea and health status in Asian COPD patients.

This 12-week, double-blind study compared the efficacy, safety, and tolerability of indacaterol to that of placebo in patients with moderate-to-severe COPD.MethodsEfficacy variables included 24-h trough FEV1(mean of 23 h 10 min and 23 h 45 min post-dose) at Week 12 (primary endpoint) and after Day 1, and the percentage of COPD days with poor control (i.e., worsening symptoms). Safety was assessed by adverse events (AEs), mean serum potassium and blood glucose, QTc (Fridericia), and vital signs.ResultsPatients were randomised (n = 416, mean age 63 years) to receive either indacaterol 150μg o.d. (n = 211) or placebo (n = 205) via a single-dose dry-powder inhaler; 87.5% completed the study. Trough FEV1(LSM ± SEM) at Week 12 was 1.48 ± 0.018 L for indacaterol and 1.35 ± 0.019 L for placebo, a clinically relevant difference of 130 ± 24 mL (p ...
