Cardiovascular safety of mometasone/indacaterol and mometasone/indacaterol/glycopyrronium once-daily fixed-dose combinations in asthma:pooled analysis of phase 3 trials

OBJECTIVE: To evaluate cardiovascular safety of two new inhaled fixed-dose combinations for treatment of asthma: (i) the inhaled corticosteroid/long-acting beta2-agonist (ICS/LABA) mometasone furoate/indacaterol acetate (MF/IND), (ii) the ICS/LABA/long-acting muscarinic antagonist (LAMA) MF/IND/glycopyrronium bromide (GLY). METHODS: Patient-level data were pooled from four randomized trials, including 52-week studies PALLADIUM (n = 2216) and IRIDIUM (n = 3092), 24-week study ARGON (n = 1426), and 12-week study QUARTZ (n = 802). Cardio-/cerebrovascular (CCV) event frequencies were examined in the following comparisons: (1) LABA effect: pooled-dose MF/IND vs. pooled-dose MF; (2) LAMA effect: pooled-dose MF/IND/GLY vs. pooled-dose MF/IND; (3) ICS-dose effects: (a) high-dose MF/IND vs. medium-dose MF/IND, (b) high-dose MF/IND/GLY vs. medium-dose MF/IND/GLY; (4) intra-class effects: (a) high-dose MF/IND vs. Fluticasone/Salmeterol (F/S), (b) high-dose MF/IND/GLY vs. F/S + Tiotropium (TIO). Risk estimates (percentage of patients with ≥1 CCV event) and risk differences (RDs) with 95% confidence intervals (CIs) were calculated for each comparison. RESULTS: The frequency of CCV events was low, without notable differences between comparison groups. Risk estimates and corresponding RDs (95% CIs) were as follows: (1) pooled-dose MF/IND = 2.35%, pooled-dose MF = 2.18%, RD = 0.17% (-1.00%, 1.34%); (2) pooled-dose MF/IND/GLY = 3.65%, pooled-dose MF/IND = 3.77%, RD = -0.12% (-1.63%, 1.39%); (3a) high-dose MF/IND = 3.69%, medium-dose MF/IND = 3.35%, RD = 0.34% (-1.25%, 1.94%); (3b) high-dose MF/IND/GLY = 2.84%, medium-dose MF/IND/GLY = 2.02%, RD = 0.82% (-0.49%, 2.13%); (4a) high-dose MF/IND = 3.69%, F/S = 2.82%, RD = 0.87% (-0.66%, 2.40%); (4b) high-dose MF/IND/GLY = 1.26%, F/S + TIO = 1.05%, RD = 0.21% (-1.26%, 1.68%). CONCLUSIONS: There was no evidence of increased cardiovascular risk attributable to the addition of IND to MF or addition of GLY to MF/IND. Similarly, no evidence of increased cardiovascular risk was observed with an increase in the ICS-dose or relative to F/S ± TIO

One time a day mometasone/indacaterol fixed-dose combination versus two times a day fluticasone/salmeterol in patients with inadequately controlled asthma:pooled analysis from PALLADIUM and IRIDIUM studies

BACKGROUND: Despite currently available standard-of-care inhaled corticosteroid (ICS)/long-acting β(2)-agonist therapies, a substantial proportion of patients with asthma remain inadequately controlled. This pooled analysis evaluated efficacy and safety of mometasone furoate/indacaterol acetate (MF/IND) versus fluticasone propionate/salmeterol xinafoate (FLU/SAL) in patients with inadequately controlled asthma. METHODS: This analysis included patients from PALLADIUM (NCT02554786) and IRIDIUM (NCT02571777) studies who received high-dose MF/IND (320/150 µg) or medium-dose MF/IND (160/150 µg) one time a day or high-dose FLU/SAL (500/50 µg) two times a day for 52 weeks. Reduction in asthma exacerbations, improvement in lung function, asthma control, and safety were evaluated for 52 weeks. RESULTS: In total, 3154 patients (high-dose MF/IND, n=1054; medium-dose MF/IND, n=1044; high-dose FLU/SAL, n=1056) were included. High-dose MF/IND showed 26%, 22% and 19% reductions in rate of severe, moderate or severe, and all (mild, moderate and severe) exacerbations versus high-dose FLU/SAL, respectively, over 52 weeks (all, p<0.05). High-dose MF/IND improved trough FEV(1) versus high-dose FLU/SAL at weeks 26 (Δ, 43 mL, p=0.001) and 52 (Δ, 51 mL, p<0.001). Reductions in asthma exacerbation rate and improvement in trough FEV(1) with medium-dose MF/IND were comparable with high-dose FLU/SAL over 52 weeks. All treatments improved Asthma Control Questionnaire-7 score from baseline to 52 weeks with no difference between treatments. Safety was comparable between high-dose MF/IND and high-dose FLU/SAL. CONCLUSIONS: One time a day, single-inhaler, high-dose MF/IND reduced asthma exacerbations and improved lung function versus two times a day, high-dose FLU/SAL in patients with inadequately controlled asthma. Similarly, improved outcomes were seen with one time a day, medium-dose MF/IND and two times a day, high-dose FLU/SAL, but at a lower ICS dose

Mometasone/Indacaterol/Glycopyrronium (MF/IND/GLY) and MF/IND at Different MF Strengths versus Fluticasone Propionate/ Salmeterol Xinafoate (FLU/SAL) and FLU/SAL+ Tiotropium in Patients with Asthma

Background: Once-daily, single-inhaler mometasone furoate/indacaterol acetate/glycopyrronium bromide (MF/IND/GLY, an ICS/ LABA/LAMA) and MF/IND (an ICS/LABA) via Breezhaler® have been approved for the maintenance treatment of patients with asthma inadequately controlled with medium-or high-dose ICS or medium-or high-dose ICS/LABA treatment. Objective: Once-daily (o.d.) formulations of MF/IND/GLY and MF/IND at different MF dose strengths have been compared with twice-daily (b.i.d.) fluticasone propionate/salmeterol xinafoate (FLU/SAL), and b.i.d. FLU/SAL+ o.d. tiotropium (TIO) in the PALLADIUM, IRIDIUM and ARGON studies. Methods: The similarity in study design and consistent outcomes in these studies prompted the pooling of data in this review to better characterise these novel once-daily controller formulations. Results: Pooled data from PALLADIUM and IRIDIUM studies showed comparable or greater efficacy with o.d. MF/IND formulations versus b.i.d. FLU/SAL. The o.d. MF/IND/GLY was superior to b.i.d. FLU/SAL in the IRIDIUM study, and similar to, if not more efficacious than b.i.d. FLU/SAL + o.d. TIO in the ARGON study. Conclusion: These formulations therefore provide novel once-daily treatment options for patients across asthma severity and flexibility for clinicians to step-up or step-down the treatment using the same device and formulations.</p

Ge Interface Engineering with Ozone-oxidation for Low Interface State Density

Passivation of Ge has been a critical issue for Ge MOS applications in future technology nodes. In this letter, we introduce ozone-oxidation to engineer Ge/insulator interface. Interface states (D{sub it}) values across the bandgap and close to conduction bandedge were extracted using conductance technique at low temperatures. D{sub it} dependency on growth conditions was studied. Minimum D{sub it} of 3 x 10{sup 11} cm{sup -2} V{sup -1} was demonstrated. Physical quality of the interface was investigated through Ge 3d spectra measurements. We found that the interface and D{sub it} is strongly affected by the distribution of oxidation states and quality of the suboxide

Ligelizumab treatment for severe asthma: learnings from the clinical development programme

Objective: Ligelizumab is a humanised IgG1 anti-IgE antibody that binds IgE with higher affinity than omalizumab. Ligelizumab had greater efficacy than omalizumab on inhaled and skin allergen provocation responses in mild allergic asthma. This multi-centre, randomised, double-blind study was designed to test ligelizumab in severe asthma patients not adequately controlled with high-dose inhaled corticoids plus long-acting β2-agonist. Methods: Patients received 16 weeks ligelizumab (240 mg q2w), omalizumab or placebo subcutaneously, and ACQ-7 was measured as primary outcome at Week 16. In addition, the study generated dose-ranging data of ligelizumab and safety data. Results: A total of 471 patients, age 47.4 ± 13.36 years, were included in the study. Treatment with ligelizumab did not significantly improve asthma control (ACQ-7) and exacerbation rates compared to omalizumab and placebo. Therefore, primary and secondary objectives of the study were not met. The compound was well tolerated, and the safety profile showed no new safety findings. Pharmacokinetic data demonstrated faster clearance and lower serum concentrations of ligelizumab than historical omalizumab data, and exploratory in vitro data showed differential IgE blocking properties relative to FcεRI and FcεRII/CD23 between the two compounds. Conclusion: Ligelizumab failed to demonstrate superiority over placebo or omalizumab. Although ligelizumab is more potent than omalizumab at inhibiting IgE binding to the high-affinity FcεRI, there is differential IgE blocking properties relative to FcεRI and FcεRII/CD23 between the two compounds. Therefore, the data suggest that different anti-IgE antibodies might be selectively efficacious for different IgE-mediated diseases

Once-daily, single-inhaler mometasone-indacaterol-glycopyrronium versus mometasone-indacaterol or twice-daily fluticasone-salmeterol in patients with inadequately controlled asthma (IRIDIUM): a randomised, double-blind, controlled phase 3 study

Background: Patients with asthma who are inadequately controlled on inhaled corticosteroid–long-acting β2-adrenoceptor agonist (ICS–LABA) combinations might benefit from the addition of a long-acting muscarinic receptor antagonist. The aim of the IRIDIUM study was to assess the efficacy and safety of a once-daily, single-inhaler combination of mometasone furoate, indacaterol acetate, and glycopyrronium bromide (MF–IND–GLY) versus ICS–LABA in patients with inadequately controlled asthma. Methods: In this 52-week, double-blind, double-dummy, parallel-group, active-controlled phase 3 study, patients were recruited from 415 sites across 41 countries. Patients aged 18 to 75 years with symptomatic asthma despite treatment with medium-dose or high-dose ICS–LABA, at least one exacerbation in the previous year, and a percentage of predicted FEV1 of less than 80% were included. Enrolled patients were randomly assigned (1:1:1:1:1) via interactive response technology to receive medium-dose or high-dose MF–IND–GLY (80 μg, 150 μg, 50 μg; 160 μg, 150 μg, 50 μg) or MF–IND (160 μg, 150 μg; 320 μg, 150 μg) once daily via Breezhaler, or high-dose fluticasone–salmeterol (FLU–SAL; 500 μg, 50 μg) twice daily via Diskus. The primary outcome was change from baseline in trough FEV1 with MF–IND–GLY versus MF–IND at week 26 in patients in the full analysis set, analysed by means of a mixed model for repeated measures. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT02571777, and is completed. Findings: Between Dec 8, 2015, and Jun 14, 2019, 3092 of 4851 patients screened were randomly assigned (medium-dose MF–IND–GLY, n=620; high-dose MF–IND–GLY, n=619; medium-dose MF–IND, n=617; high-dose MF–IND, n=618; high-dose FLU–SAL, n=618). 2747 (88·8%) patients completed the 52-week treatment and 321 (10·4%) started but discontinued study treatment prematurely. Medium-dose MF–IND–GLY (treatment difference [Δ] 76 mL [95% CI 41–111]; p<0·001) and high-dose MF–IND–GLY (Δ 65 mL [31–99]; p<0·001) showed superior improvement in trough FEV1 versus corresponding doses of MF–IND at week 26. Improvements in trough FEV1 were greater for both medium-dose MF–IND–GLY (99 mL [64–133]; p<0·001) and high-dose MF–IND–GLY (119 mL [85–154]; p<0·001) than for high-dose FLU–SAL at week 26. Overall, the incidence of adverse events was balanced across the treatment groups. Seven deaths were reported (one with medium-dose MF–IND–GLY, two with high-dose MF–IND–GLY, and four with high-dose MF–IND) during the study; none of these deaths was considered by the investigators to be caused by study drugs or other study-related factors. Interpretation: Once-daily, single-inhaler MF–IND–GLY improved lung function versus ICS–LABA combinations (MF–IND and FLU–SAL) in patients with inadequately controlled asthma. The safety profile was similar across treatment groups. MF–IND–GLY therefore constitutes a good treatment option in these patients. Funding: Novartis Pharmaceuticals
