Efficacy and Safety of Roflumilast in Korean Patients with COPD.

ABSTRACT: PURPOSE:Roflumilast is the only oral phosphodiesterase 4 inhibitor approved to treat chronic obstructive pulmonary disease (COPD) patients [post-bronchodilator forced expiratory volume in 1 second (FEV?) <50% predicted] with chronic bronchitis and a history of frequent exacerbations. This study evaluated the efficacy and safety of roflumilast in Korean patients with COPD and compared the efficacy based on the severity of airflow limitation. MATERIALS AND METHODS:A post-hoc subgroup analysis was performed in Korean COPD patients participating in JADE, a 12-week, double-blinded, placebo-controlled, parallel-group, phase III trial in Asia. The primary efficacy endpoint was the mean [least-squares mean adjusted for covariates (LSMean)] change in post-bronchodilator FEV? from baseline to each post-randomization visit. Safety endpoints included adverse events (AEs) and changes in laboratory values, vital signs, and electrocardiograms. RESULTS:A total of 260 Korean COPD patients were recruited, of which 207 were randomized to roflumilast (n=102) or placebo (n=105) treatment. After 12 weeks, LSMean post-bronchodilator FEV? increased by 43 mL for patients receiving roflumilast and decreased by 60 mL for those taking placebo. Adverse events were more common in the roflumilast group than in the placebo group; however, the types and frequency of AEs were comparable to those reported in previous studies. CONCLUSION:Roflumilast significantly improved lung function with a tolerable safety profile in Korean COPD patients irrespective of the severity of airflow limitation.

<h4>Purpose</h4>Roflumilast is the only oral phosphodiesterase 4 inhibitor approved to treat chronic obstructive pulmonary disease (COPD) patients [post-bronchodilator forced expiratory volume in 1 second (FEV₁) <50% predicted] with chronic bronchitis and a history of frequent exacerbations. This study evaluated the efficacy and safety of roflumilast in Korean patients with COPD and compared the efficacy based on the severity of airflow limitation.<h4>Materials and methods</h4>A post-hoc subgrou ...[more]

Project description:PurposeIn the Phase III SIROCCO trial (NCT01928771), benralizumab significantly reduced asthma exacerbations and improved lung function and symptoms for patients with severe, uncontrolled eosinophilic asthma. The aim of this subgroup analysis was to evaluate efficacy and safety of benralizumab for Korean patients in SIROCCO.MethodsSIROCCO was a randomized, double-blind, parallel-group, placebo-controlled trial of 1,204 patients aged 12-75 years with severe asthma uncontrolled by high-dosage inhaled corticosteroids/long-acting β₂-agonists (ICS/LABA). Patients received benralizumab 30 mg every 4 weeks (Q4W) or every 8 weeks (Q8W; first 3 doses Q4W) or placebo Q4W for 48 weeks. The primary analysis population comprised patients with blood eosinophil counts ≥ 300 cells/μL. This subgroup analysis evaluated Korean patients from this group.ResultsOf 122 Korean patients randomized, 86 had blood eosinophil counts ≥ 300 cells/μL. Benralizumab reduced the annual asthma exacerbation rate by 70% (Q4W: rate estimate 0.79, rate ratio 0.30 [95% confidence interval {CI}, 0.13-0.65], nominal P = 0.003; n = 28) and 85% (Q8W: rate estimate 0.40, rate ratio 0.15 [95% CI, 0.06-0.36], nominal P < 0.001; n = 30) vs. placebo (rate estimate 2.67, n = 28). Prebronchodilator forced expiratory volume in 1 second was increased with benralizumab treatment by 0.270 L (Q4W: 95% CI, 0.039-0.500, nominal P = 0.023; n = 28) and 0.362 L (Q8W: 95% CI, 0.143-0.582, nominal P = 0.002; n = 30) vs. placebo (n = 27). Total asthma symptom score was similar for patients receiving either benralizumab Q4W (-0.27 [95% CI, -0.83 to 0.30], nominal P = 0.356; n = 27) or benralizumab Q8W (0.10 [95% CI, -0.44 to 0.65], nominal P = 0.708; n = 30) vs. placebo (n = 28). Drug-related adverse events were experienced by 2%, 8%, and 5% of patients in the placebo, benralizumab Q4W, and benralizumab Q8W arms.ConclusionsBenralizumab reduced annual asthma exacerbation rates, increased lung function, and was well-tolerated by Korean patients with severe, uncontrolled eosinophilic asthma.

Project description:BackgroundRoflumilast is a targeted inhibitor of phosphodiesterase (PDE)-4 and has been approved for treatment of severe chronic obstructive pulmonary disease for more than a decade. Generic versions are available in the United States. PDE-4 is involved in the psoriasis pathogenesis, but the efficacy and safety of oral roflumilast in patients with psoriasis have not previously been studied.MethodsA company-independent, multicenter, randomized, double-blind, placebo-controlled trial (ClinicalTrials.govNCT04549870). Patients were randomized 1:1 to receive monotherapy with oral roflumilast 500 μg once daily or placebo. At week 12, placebo patients were switched to open-label roflumilast through week 24. The primary endpoint was a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI75) at week 12.FindingsIn all, 46 patients were randomized (roflumilast, n = 23; placebo, n = 23). At week 12, significantly more patients in the active arm achieved PASI75 (8 of 23 patients [35%]) vs. placebo (0 of 23 patients [0%], with a difference vs. placebo of 8 [35%] patients, 95% CI: 3 [13%]-13 [57%] patients) (p = 0.014). At week 24, 15 (65%), 10 (44%), 5 (22%), and 2 (9%) of patients treated with roflumilast from week 0 had PASI50, PASI75, PASI90, and PASI100 responses (key secondary endpoints), respectively. The most prevalent, drug-related adverse events in both treatment groups were transient gastrointestinal symptoms, weight-loss, headache, and insomnia. A total of three patients (roflumilast n = 2; placebo, n = 1) discontinued therapy due to adverse events.InterpretationOral roflumilast was efficacious and safe in treating moderate-to-severe plaque psoriasis over 24 weeks. With generic versions available, this drug may represent an inexpensive and convenient alternative to established systemic psoriasis treatments.FundingFinancial support was received from Herlev and Gentofte Hospital, University of Copenhagen, and independent grants from private foundations in Denmark. No pharmaceutical company, including the market authorization holder of roflumilast, was involved in the study at any point.
