Bimekizumab efficacy and safety in Korean patients with moderate to severe plaque psoriasis: A phase 3, randomized, placebo-controlled, double-blinded study.

Bimekizumab treatment has demonstrated significant improvements in clinical outcomes in patients with moderate to severe plaque psoriasis; however, studies so far have focused on predominantly White patient populations from North America and Europe, with one smaller study in a Japanese population. Here, clinical responses, safety, and tolerability of bimekizumab treatment in Korean patients are reported. Korean patients with moderate to severe plaque psoriasis were randomized to bimekizumab 320 mg every 4 weeks (Q4W) or placebo Q4W to week 16. Co-primary efficacy end points were achievement of ≥90% improvement from baseline in the Psoriasis Area and Severity Index (PASI 90) and Investigator's Global Assessment score of 0/1 (clear/almost clear) at week 16. Secondary efficacy end points included achievement of PASI 75 at week 4 and Dermatology Life Quality Index 0/1 at week 16. Safety outcomes were also assessed. Statistical analysis of the co-primary efficacy end points was performed using a type I error rate, at a two-sided α level of 0.05. Overall, 47 Korean patients were randomized to treatment (bimekizumab: 32, placebo: 15). At week 16, bimekizumab-treated patients had significantly higher clinical responses versus placebo-treated patients (PASI 90: 81.3% vs. 0%; IGA 0/1: 87.5% vs. 0%, p < 0.001 for both). Bimekizumab showed a rapid onset of clinical response, with 75.0% of patients achieving PASI 75 by week 4 (0% in placebo patients [nominal p < 0.001]). A higher proportion of bimekizumab-treated patients achieved DLQI 0/1 at week 16 (46.9% vs. 6.7% in placebo patients, nominal p = 0.007), indicating greater improvements in health-related quality of life (HRQoL) following bimekizumab treatment. Bimekizumab was well-tolerated in Korean patients, with no new safety signals identified. Treatment with bimekizumab led to rapid improvements in clinical responses and HRQoL versus placebo in Korean patients, consistent with responses in global populations. These findings suggest that bimekizumab is an effective and well-tolerated treatment option in Korean patients with psoriasis.

Health-related quality of life from the FALCON phase III randomised trial of fulvestrant 500 mg versus anastrozole for hormone receptor-positive advanced breast cancer.

BACKGROUND: The phase III randomised FALCON trial (NCT01602380) demonstrated improved progression-free survival with fulvestrant 500 mg versus anastrozole 1 mg in endocrine therapy-naïve postmenopausal women with hormone receptor-positive (HR+) locally advanced or metastatic breast cancer (LA/MBC). Furthermore, overall health-related quality of life (HRQoL) was maintained and comparable for fulvestrant and anastrozole. Here, we present additional analyses of patient-reported HRQoL outcomes from FALCON. METHODS: Women with endocrine therapy-naïve HR+ LA/MBC were randomised 1:1 to fulvestrant (days 0, 14, 28, then every 28 d) or anastrozole (daily) until disease progression or discontinuation. HRQoL was assessed by FACT-B questionnaire (TOI and FACT-B total score) at randomisation and every 12 weeks during treatment. HRQoL data post-treatment (with or without progression) were also collected. RESULTS: In total, 462 patients were randomised (fulvestrant, n = 230; anastrozole, n = 232). Compliance to FACT-B overall ranged from 60.0 to 97.4%. Mean change from baseline in TOI and FACT-B total score remained broadly stable (approximately ± 3 points to week 132) and was similar between arms during treatment. HRQoL was also maintained in FACT-B subscales. Approximately one-third of patients had improved TOI (≥+6 points) and FACT-B (≥+8 points) total scores from baseline up to week 120 and 132, respectively, of treatment with fulvestrant (ranges 26.4-45.0% and 22.4-35.8%, respectively) and anastrozole (ranges 18.6-32.9%, and 22.7-37.9%, respectively). CONCLUSIONS: Mean change from baseline in TOI and FACT-B total score was maintained for fulvestrant and anastrozole; similar proportions of patients in both arms had improved TOI and FACT-B total scores.

Progression-free survival results in postmenopausal Asian women: subgroup analysis from a phase III randomized trial of fulvestrant 500 mg vs anastrozole 1 mg for hormone receptor-positive advanced breast cancer (FALCON).

BACKGROUND: The international, phase III FALCON study (NCT01602380) in postmenopausal patients with hormone receptor-positive, locally advanced/metastatic breast cancer (LA/MBC) who had not received prior endocrine therapy, demonstrated statistically significant improvement in progression-free survival (PFS) for patients who received fulvestrant 500 mg vs anastrozole 1 mg. This subgroup analysis evaluated PFS in Asian (randomized in China, Japan, or Taiwan) and non-Asian patients from the FALCON study. METHODS: Eligible patients (estrogen receptor- and/or progesterone receptor-positive LA/MBC; World Health Organization performance status 0-2; ≥ 1 measurable/non-measurable lesion[s]) were randomized. PFS was assessed via Response Evaluation Criteria in Solid Tumours version 1.1, surgery/radiotherapy for disease worsening, or death (any cause). Secondary endpoints included: objective response rate, clinical benefit rate, duration of response, and duration of clinical benefit. Consistency of effect across subgroups was assessed via hazard ratios and 95% confidence intervals (CIs) using a log-rank test. Adverse events (AEs) were evaluated. RESULTS: Of the 462 randomized patients, the Asian and non-Asian subgroups comprised 67 and 395 patients, respectively. In the Asian subgroup, median PFS was 16.6 and 15.9 months with fulvestrant and anastrozole, respectively (hazard ratio 0.81; 95% CI 0.44-1.50). In the non-Asian subgroup, median PFS was 16.5 and 13.8 months, respectively (hazard ratio 0.79; 95% CI 0.62-1.01). Secondary outcomes were numerically improved with fulvestrant vs anastrozole in both subgroups. AE profiles were generally consistent between Asian and non-Asian subgroups. CONCLUSIONS: Results of this subgroup analysis suggest that treatment effects in the Asian patient subgroup are broadly consistent with the non-Asian population.

Uncontrolled persistent allergic asthma in practice: eXpeRience registry baseline characteristics.

BACKGROUND: Medical registries can be used to assess and monitor the effectiveness and safety of approved therapy, and provide insights into how quality of care can be optimized. METHODS: The post-marketing, non-interventional, observational registry (eXpeRience) aims to collect data on the treatment effectiveness and safety of omalizumab in 'real-world' practice. The baseline characteristics of patients with uncontrolled allergic asthma receiving omalizumab therapy and included in the first interim analysis of this observational registry are reported. RESULTS: A total of 294 patients were included in the first interim analysis. Of these patients, 271 (92.2%) were active in the registry at the time of reporting. At baseline, the mean duration of allergic asthma was approximately 19 years, with over 87% of patients testing positive for a perennial allergen. Mean % predicted FEV(1) and serum total IgE levels were 62.4% and 316.7 IU/mL, respectively. Asthma was uncontrolled for approximately 62% of patients, while around 23% were partly controlled. The majority of patients were being treated with multiple asthma controller medications, including inhaled-corticosteroids, long-acting ß(2)-agonists and leukotriene receptor antagonists, and 28% of patients were also receiving maintenance oral corticosteroids. Concomitant diseases were present in many patients, the most common being perennial allergic rhinitis (42.5%). CONCLUSIONS: Demographic and disease characteristics highlight the unmet clinical need in patients with uncontrolled allergic asthma. Future analyses from this study will further determine the real-life effectiveness and safety of omalizumab.

Formoterol mono- and combination therapy with tiotropium in patients with COPD: a 6-month study.

Although guidelines recommend combining long-acting bronchodilators in COPD, data are limited. We examined the clinical efficacy and safety of formoterol, tiotropium and the combination in patients with COPD. Eight hundred and forty-seven patients with COPD (mean FEV(1) 52% predicted; FEV(1)/FVC 53%) were randomized to receive one of the following four treatments for 24 weeks: formoterol 10 microg b.i.d. plus tiotropium 18 microg o.d.; formoterol 10 microg b.i.d.; tiotropium 18 microg o.d., or placebo. The study was partially blinded (formoterol and placebo). For the primary endpoint, FEV(1) 2h post-dose after 24 weeks, there were small differences in favour of the combination therapy versus formoterol (0.07 L, p=0.044) or tiotropium (0.06 L, p=0.066). All three treatments were superior to placebo (p<0.001). The combination was statistically superior to monotherapy for: the primary endpoint (p=0.044 vs. formoterol); FEV(1) 5 min after the first dose (p<0.001) and at 12 weeks (p<0.05 vs. tiotropium); and peak expiratory flow averaged over the first 6 weeks (p<0.001 vs. both). The three active treatments were significantly more effective than placebo for secondary endpoints: COPD-related 'bad days', symptoms, use of rescue medication and peak expiratory flow, and aspects of health-related quality of life. The overall incidence of adverse events was similar with all active treatments, although COPD-related adverse events were more common with tiotropium. Combined bronchodilator therapy may be a valuable treatment option for patients with COPD.

Effects of formoterol on exercise tolerance in severely disabled patients with COPD.

OBJECTIVE: We wished to evaluate the effects of inhaled formoterol, a long-acting beta(2)-adrenergic agonist, on exercise tolerance and dynamic hyperinflation (DH) in severely disabled chronic obstructive pulmonary disease (COPD) patients. DESIGN: In a two-period, crossover study, 21 patients with advanced COPD (FEV(1)=38.8+/-11.7% predicted, 16 patients GOLD stages III-IV) were randomly allocated to receive inhaled formoterol fumarate 12 microg twice daily for 14 days followed by placebo for 14 days, or vice versa. Patients performed constant work-rate cardiopulmonary exercise tests to the limit of tolerance (Tlim) on a cycle ergometer: inspiratory capacity (IC) was obtained at rest and each minute during exercise. Baseline and transitional dyspnoea indices (BDI and TDI) were also recorded. RESULTS: Eighteen patients completed both treatment periods. Formoterol treatment was associated with an estimated increase of 130 s in Tlim compared with placebo (P=0.052): this corresponded to a 37.8% improvement over placebo (P=0.012). Enhanced exercise tolerance after bronchodilator was associated with diminished DH marked by higher inspiratory reserve and tidal volumes at isotime and exercise cessation (P<0.05). There was no significant difference between formoterol and placebo on exercise dyspnoea ratings; however, all domains of the TDI improved (P
