Dupilumab, a fully human anti-interleukin-4 receptor α monoclonal antibody, inhibits interleukin-4 and interleukin-13 signalling, key drivers of type-2-mediated inflammation. Adults with uncontrolled persistent asthma who are receiving medium-to-high-dose inhaled corticosteroids plus a long-acting β2 agonist require additional treatment options as add-on therapy. We aimed to assess the efficacy and safety of dupilumab as add-on therapy in patients with uncontrolled persistent asthma on medium-to-high-dose inhaled corticosteroids plus a long-acting β2 agonist, irrespective of baseline eosinophil count. We did this randomised, double-blind, placebo-controlled, parallel-group, pivotal phase 2b clinical trial at 174 study sites across 16 countries or regions. Adults (aged ≥18 years) with an asthma diagnosis for 12 months or more based on the Global Initiative for Asthma 2009 Guidelines receiving treatment with medium-to-high-dose inhaled corticosteroids plus a long-acting β2 agonist were eligible for participation. Patients were randomly assigned (1:1:1:1:1) to receive subcutaneous dupilumab 200 mg or 300 mg every 2 weeks or every 4 weeks, or placebo, over a 24-week period. The primary endpoint was change from baseline at week 12 in forced expiratory volume in 1 s (FEV1 in L) in patients with baseline blood eosinophil counts of at least 300 eosinophils per μL assessed in the intention-to-treat population. Safety outcomes were assessed in all patients that received at least one dose or part of a dose of study drug. This trial is registered at ClinicalTrials.gov, number NCT01854047, and with the EU Clinical Trials Register, EudraCT number 2013-000856-16. 769 patients (158 in the placebo group and 611 in the dupilumab groups) received at least one dose of study drug. In the subgroup with at least 300 eosinophils per μL, the greatest increases (200 mg every 2 weeks, p=0·0008; 300 mg every 2 weeks, p=0·0063) in FEV1 compared with placebo were observed at week 12 with doses every 2 weeks in the 300 mg group (mean change 0·39 L [SE 0·05]; mean difference 0·21 [95% CI 0·06–0·36; p=0·0063]) and in the 200 mg group (mean change 0·43 L [SE 0·05]; mean difference 0·26 [0·11–0·40; p=0·0008]) compared with placebo (0·18 L [SE 0·05]). Similar significant increases were observed in the overall population and in the fewer than 300 eosinophils per μL subgroup (overall population: 200 mg every 2 weeks, p<0·0001; 300 mg every 2 weeks, p<0·0001; <300 eosinophils per μL: 200 mg every 2 weeks, p=0·0034; 300 mg every 2 weeks, p=0·0086), and were maintained to week 24. Likewise, dupilumab every 2 weeks produced the greatest reductions in annualised rates of exacerbation in the overall population (70–70·5%), the subgroup with at least 300 eosinophils per μL (71·2–80·7%), and the subgroup with fewer than 300 eosinophils per μL (59·9–67·6%). The most common adverse events with dupilumab compared with placebo were upper respiratory tract infections (33–41% vs 35%) and injection-site reactions (13–26% vs 13%). Dupilumab increased lung function and reduced severe exacerbations in patients with uncontrolled persistent asthma irrespective of baseline eosinophil count and had a favourable safety profile, and hence in addition to inhaled corticosteroids plus long-acting β2-agonist therapy could improve the lives of patients with uncontrolled persistent asthma compared with standard therapy alone.

In the clinic, approximately 30% of children with adenoid hypertrophy (AH) concomitant with allergic rhinitis (AR) report poor responses to intranasal steroids. To determine whether the combination of mometasone furoate (MF) and oxymetazoline (OXY) is more effective than either agent alone, we performed a two-stage, parallel, randomized, double-blind, double-dummy, clinical trial with 240 AH children with concomitant perennial AR. During the first stage, all children were randomly assigned to the MF or control group for six weeks of treatment. During the second stage, the non-responders from stage one were randomly assigned to 4 groups for 8 weeks of treatment that involved receiving the following treatments: MF/OXY, MF/placebo, placebo/OXY, or placebo/placebo. During the first stage of treatment, 39% of the responders treated with MF achieved greater reductions in total and individual symptom scores than did those on placebo. During the second stage of treatment, the nasal congestion scores of the MF/OXY group significantly decreased. The adenoid/choana ratio of the MF/OXY-treated group decreased and the nasal volume increased significantly. Our results suggest that the combination of OXY and MF is effective and safe for the treatment of AH children with concomitant AR and has a rapid onset of action.

Background A once-daily (o.d.) fixed-dose combination of indacaterol acetate (IND), glycopyrronium bromide (GLY), and mometasone furoate (MF) delivered via the Breezhaler ® device (IND/GLY/MF) is being developed for treatment of asthma. This study compared steady-state pharmacokinetics of IND, GLY and MF between Japanese and Caucasian male subjects after multiple inhalations of IND/GLY/MF o.d. Methods This was a single-center, open-label, 2-treatment crossover study with a 21-day washout period. Japanese and Caucasian subjects received IND/GLY/MF 150/50/80 μg (inhaled corticosteroid [ICS] medium-dose) or 150/50/160 μg o.d. (ICS high-dose) for 14 days in each period. Pharmacokinetics were characterized up to 24 h post-dose on Days 1 and 14. Results In total, 16 Japanese (median age 31 years [range 20–40 years], mean weight 68.3 kg) and 17 Caucasian subjects (median age 27 years [range 21–43 years], mean weight 75.0 kg) were randomized. Geometric mean ratios (Japanese/Caucasian) [90% confidence interval (CI)] for C max for IND, GLY and MF at the high ICS dose on Day 14 were 1.31 [1.13, 1.51] 1.38 [1.13, 1.69] and 1.07 [0.969, 1.18], respectively. Geometric mean ratios (Japanese/Caucasian) [90% CI] for AUC 0–24h on Day 14 for IND, GLY and MF at the high ICS dose were 1.17 [1.01, 1.35], 1.05 [0.920, 1.20] and 1.15 [1.05, 1.27] respectively. Similar trends were noted for all components for the medium ICS dose treatment. IND/GLY/MF was safe and well tolerated; no AEs suspected to be study drug-related were observed. Conclusion Pharmacokinetics of IND, GLY and MF (high and medium dose) when delivered as a fixed-dose combination were comparable between Japanese and Caucasian subjects. The IND/GLY/MF combination at the administrated doses was safe and well tolerated in both ethnic groups.

For the last three decades, the guidelines for asthma management have supported a stepwise therapeutic approach, based on the administration of controller medications (especially inhaled corticosteroids) complemented by on-demand use of rescue medication. Classically, the rescue medication recommended comprised short-acting β agonists (SABA). Some years ago, the use of Symbicort Maintenance and Reliever Therapy (SMART) demonstrated the benefits of a combination of budesonide-formoterol, an inhaled corticosteroid, and a long-acting β agonist (ICS-LABA) as rescue medication in moderate and severe asthma. The results were enthusiastically received, and this therapeutic option was adopted in the guidelines for moderate to severe asthma patients. Recently, four trials (two randomised placebo control trials under the auspices of the SYGMA project and two real-life studies, Novel START, and the PRACTICAL trial) have explored the potential benefits of substituting SABA with budesonide-formoterol as rescue medication in mild asthma patients. The SYGMA 1 and 2 studies showed that the combination with formoterol-budesonide as rescue medication provides better asthma control than short-acting β-agonists alone in GINA step 2 patients, although the superiority was slight. Compared to budesonide maintenance therapy, the fixed combination of ICS-LABA on demand provides poorer asthma control. Regarding exacerbations, the fixed dose ICS-LABA combination on demand showed the same benefits for the prevention of exacerbations as chronic ICS treatment in mild asthma patients. The Novel START study, which assessed a population with milder symptoms, concluded that the fixed dose ICS-LABA combination used as needed was superior to SABA (albuterol) as needed for the prevention of asthma exacerbations. These results in fact show that, in undertreated GINA step 2 with only SABA as needed, ICS-LABA is more effective than SABA. The authors of PRACTICAL concluded that the study provided modest evidence that the ICS-LABA combination used as-needed for symptom relief reduces the rate of severe exacerbations compared with maintenance low-dose budesonide plus terbutaline as needed, although the study was not limited to mild asthma since according to the treatment consumed, it was evident that they had recruited some moderate asthma patients. Despite this poor evidence, and ignoring the clinical histological benefits of chronic inhaled corticosteroids (especially when administered promptly), GINA 2019 recently recommended daily low dose ICS or ICS-LABA as needed as a first option for step 2 patients. For step 1, symptom-driven or as-needed treatment with ICS-LABA is recommended rather than SABA alone (the preferred option until the last GINA update). Finally, the SIENA study showed that 73% of patients with mild asthma do not have an eosinophilic phenotype and that these patients have a similar clinical response to ICS (mometasone) and antimuscarinic drugs (tiotropium), results that challenge the indication of a drug combination that incorporates ICS as a first option. Overall, we believe there is insufficient evidence for the systematic recommendation of as-needed ICS-LABA instead of SABA on request for GINA step 1 or as a replacement for chronic ICS in GINA step 2.

In this trial involving patients with mild, persistent asthma, there was no significant difference in therapeutic effect between an inhaled glucocorticoid (mometasone) and placebo in patients with a low sputum eosinophil level (<2%), which was reported in nearly three quarters of the patients.

Allergic rhinitis is a common childhood disease. Although various drugs have been used to treat allergic rhinitis, including nasal corticosteroids, antileukotrienes, and antihistamines, there is still controversy about the optimal dose and the best combination with the highest efficacy. Higher doses of antihistamines are recommended for better control of urticaria, but there is insufficient evidence regarding the efficacy of increased doses of antihistamines in allergic rhinitis. The aim of the study was to evaluate the effectiveness of different drug combinations in the treatment of children with allergic rhinitis. Sixty-four children with persistent moderate to severe allergic rhinitis were enrolled and randomly divided into 4 groups. All children received mometasone furoate nasal spray once daily. In addition to mometasone, each group received one of the following drugs or drug combinations: daily desloratadine, twice daily desloratadine, montelukast, or a combination of desloratadine and montelukast. The severity of symptoms before and after the intervention was evaluated based on the total nasal symptoms score, including sneezing, nasal congestion, nasal itching, and rhinorrhea. Sixty patients completed the study. The reduction of nasal congestion score and total nasal symptoms score in the groups receiving desloratadine twice a day and desloratadine plus montelukast was superior to the daily desloratadine group and daily montelukast groups According to this work, the treatment of allergic rhinitis with mometasone nasal spray with desloratadine twice a day or with the combination of desloratadine and montelukast was more effective than other treatment regimens.

Mometasone furoate is a synthetic corticosteroid used in the treatment of skin inflammatory conditions, hay fever and asthma. The industrial manufacturing routes to mometasone furoate are generally accompanied by the formation of numerous process impurities that need to be detected and quantified, as requested by regulatory authorities. The ready availability of such impurities in the required quantity and purity is therefore essential for toxicological studies, analytical method development and process validation. Herein, we report the multi-gram scale preparation of 21′-chloro-(16′α-methyl-3′,11′,20′-trioxo-pregna-1′,4′-dien-17′-yl)-furan-2-carboxylate (mometasone furoate EP impurity C), one of the known impurities of mometasone furoate. This study also includes the systematic investigation of the final acylation step, as well as the characterization of the difuroate enol ether intermediate and its conversion to the target impurity C.

Fixed-dose combinations of a long-acting beta agonist and an inhaled corticosteroid are more effective than the individual components in COPD. The primary study objective was to demonstrate that the combination indacaterol acetate/mometasone furoate (IND/MF [QMF149]) was non-inferior to the twice-daily combination salmeterol xinafoate/fluticasone propionate (Sal/Flu) in terms of trough FEV at week 12 (day 85). Secondary objectives were to compare the efficacy of IND/MF (QMF149) vs Sal/Flu with respect to other lung function parameters, COPD exacerbations, symptoms and dyspnea, health status/health-related quality of life, and rescue medication use. This was a 12-week multicenter, randomized, double-blind, double-dummy, parallel-group, Phase II study in patients with moderate-to-very-severe COPD, who were randomized (1:1) to IND/MF (QMF149) (150/160 µg once daily; n=316) or Sal/Flu (50/500 µg twice daily; n=313). Over 90% of patients completed the study: 94.6% in the IND/MF (QMF149) group and 92.0% in the Sal/Flu group. The primary objective of non-inferiority of IND/MF (QMF149) to Sal/Flu for trough FEV at week 12 (day 85) was met: the lower limit of the CI (95% CI: 27.7, 83.3 mL) was greater than -60 mL. The analysis for superiority of IND/MF (QMF149) to Sal/Flu demonstrated superiority of IND/MF (QMF149), with a difference of 56 mL ( <0.001). In addition, IND/MF (QMF149) treatment significantly improved COPD exacerbation-related parameters during the 12-week period. Other significant improvements with IND/MF (QMF 149) vs Sal/Flu were noted for dyspnea at week 12 and other COPD symptoms and COPD rescue medication use over the 12 weeks. The safety and tolerability profiles of both the treatments were similar. IND/MF (QMF149) (150/160 µg once daily) offered superior lung function and symptom efficacy and a favorable safety profile compared with Sal/Flu (50/500 µg twice daily) in patients with moderate-to-very severe COPD.

To observe the clinical effect of mometasone furoate cream sodium Alginate Skin Repair Mask in the treatment of atopic dermatitis (AD). By assessing the combined use of these two treatments, the study aims to address a gap in knowledge regarding the effectiveness and safety of adjuvant therapies for AD, particularly in the context of Alginate Skin Repair Mask. Eighty patients were enrolled, including 42 males and 38 females aged 20-47 years, with an average age of (32.52±5.57) years, from July 2021 to July 2022, and the patients were divided into a single group (n=40) and a combined group (n=40) by random number table method. The patients in the single group were treated with mometasone furoate cream alone, and the patients in the combination group were treated with Alginate Skin Repair Mask on the basis of the treatment of the patients in the single group. The outcome measurements included clinical treatment effect, condition change (SCORAD score), quality of life (DLQI score), adverse reactions and disease recurrence were compared between the two groups. Both groups received treatment for 1 month. After the treatment of the patients, they were followed up for a period of 3 months. The total effective rate of the single group was 80.0% (32/40), and that of the combined group was 97.5% (39/40) (P < .05). After treatment, the skin lesion area score, skin lesion degree score, pruritus insomnia score, and SCORAD total score in the combined group were significantly lower than those in the single group (35.03±9.41 vs 44.03±12.04) (all P < .05). The DLQI score of the combined group after treatment was significantly lower than that of the single group (3.72±1.53 vs 6.98±2.16) (P < .05). The incidence of adverse reactions in the single group was 22.5% (9/40), and the disease recurrence rate was 32.5% (13/40), while the incidence of adverse reactions in the combination group was 2.5% (1/40). The disease recurrence rate was 7.5% (3/40), and the incidence of adverse reactions and disease recurrence rate in the combination group were significantly lower than those in the single group (7.314, 7.812). Mometasone furoate cream sodium Alginate Skin Repair Mask has an ideal clinical effect in the treatment of atopic dermatitis. Compared with single mometasone furoate cream, the combination of sodium Alginate Skin Repair Mask can further improve the patient's condition, improve the quality of life of the patient, and reduce the risk of adverse reactions and disease recurrence. The higher total effective rate in the combined group indicates that the addition of Alginate Skin Repair Mask to the treatment regimen resulted in improved outcomes for patients with atopic dermatitis (AD). This translates to better control of the disease, reduction in symptoms, and overall improvement in the patient's condition.  However, it is important for clinicians to be aware that the use of topical glucocorticoids like mometasone furoate cream can potentially lead to adverse reactions. Some documented adverse reactions associated with long-term use of topical glucocorticoids include acne-like eruption, telangiectasia (dilation of small blood vessels), and local skin atrophy. By addressing multiple aspects of AD management, including skin barrier repair, moisturization, and inflammation control, the combination of mometasone furoate cream and Alginate Skin Repair Mask provides a more comprehensive treatment approach. This comprehensive approach may contribute to the observed reduction in recurrence rate in the combination group compared to the single group, where only mometasone furoate cream was used.

This study seeks to assess the effectiveness and safety of a combination treatment involving loratadine and mometasone furoate for patients suffering from allergic rhinitis (AR). Additionally, it explores the risk factors contributing to treatment failure, providing a theoretical basis for identifying safer and more effective AR treatments. A prospective study was carried out between January 1, 2021, and April 1, 2023, involving 116 patients with allergic rhinitis (AR) who were treated at our outpatient clinic. Participants were randomly divided into two groups: the control group (n=58), which received loratadine alone, and the study group (n=58), which received a combination of loratadine and mometasone furoate. Outcome measures included nasal symptom scores and serological markers, assessed before and after the treatment period. The effectiveness of the treatment was assessed using nasal symptom scores. Post-treatment assessments showed that both nasal symptom scores and serological markers were significantly lower in the study group compared to the control group (P<0.05). Additionally, the overall response rate was markedly higher in the study group (P<0.05). There were no significant differences in the total incidence of adverse reactions between the two groups (P>0.05). The combination of loratadine and mometasone furoate effectively alleviates clinical symptoms in patients with allergic rhinitis while demonstrating a favorable safety profile, making it a promising option for clinical use.
