Randomized Controlled Trial
BACKGROUND
Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by IgE hyperproduction and eosinophilic inflammation. The anti-IgE antibody, omalizumab, has demonstrated efficacy in patients with CRSwNP and comorbid asthma previously.
OBJECTIVE
Our aim was to determine omalizumab safety and efficacy in CRSwNP in phase 3 trials (POLYP 1 and POLYP 2).
METHODS
Adults with CRSwNP with inadequate response to intranasal corticosteroids were randomized (1:1) to omalizumab or placebo and intranasal mometasone for 24 weeks. Coprimary end points included change from baseline to week 24 in Nasal Polyp Score (NPS) and Nasal Congestion Score. Secondary end points included change from baseline to week 24 in Sino-Nasal Outcome Test-22 (SNOT-22) score, University of Pennsylvania Smell Identification Test, sense of smell, postnasal drip, runny nose, and adverse events.
RESULTS
Patients in POLYP 1 (n = 138) and POLYP 2 (n = 127) exhibited severe CRSwNP and substantial quality of life impairment evidenced by a mean NPS higher than 6 and SNOT-22 score of approximately 60. Both studies met both the coprimary end points. SNOT-22 score, University of Pennsylvania Smell Identification Test score, sense of smell, postnasal drip, and runny nose were also significantly improved for omalizumab versus placebo. In POLYP 1 and POLYP 2, the mean changes from baseline at week 24 for omalizumab versus placebo were as follows: NPS, -1.08 versus 0.06 (P < .0001) and -0.90 versus -0.31 (P = .0140); Nasal Congestion Score, -0.89 versus -0.35 (P = .0004) and -0.70 versus -0.20 (P = .0017); and SNOT-22 score, -24.7 versus -8.6 (P < .0001) and -21.6 versus -6.6 (P < .0001). Adverse events were similar between groups.
CONCLUSION
Omalizumab significantly improved endoscopic, clinical, and patient-reported outcomes in severe CRSwNP with inadequate response to intranasal corticosteroids, and it was well tolerated.

Randomized Controlled Trial
IMPORTANCE
Obstructive sleep-disordered breathing (SDB) in children is characterized by snoring and difficulty breathing during sleep. SDB affects at least 12% of otherwise healthy children and is associated with significant morbidity. Evidence from small clinical trials suggests that intranasal corticosteroids improve SDB as measured by polysomnography; however, the effect on symptoms and quality of life is unclear.
OBJECTIVE
To determine whether intranasal mometasone furoate is more effective than intranasal saline for improving symptoms and quality of life in children with SDB.
DESIGN, SETTING, AND PARTICIPANTS
The MIST trial was a multicenter, randomized, double-blind, placebo-controlled trial, recruiting participants from June 8, 2018, to February 13, 2020. Children aged 3 to 12 years who were referred to a specialist for significant SDB symptoms were included; exclusions were previous adenotonsillectomy, body mass index greater than the 97th percentile, and severe SDB. Randomization was stratified by site, and data were analyzed on an intention-to-treat basis from October 28, 2020, to September 25, 2022.
INTERVENTIONS
Participants were randomly assigned to receive mometasone furoate, 50 μg, or sodium chloride (saline), 0.9%, 1 spray per nostril daily, dispensed in identical bottles.
MAIN OUTCOMES AND MEASURES
The primary outcome was resolution of significant SDB symptoms (ie, reduction to a level no longer requiring referral to a specialist as per the American Academy of Pediatrics guidelines) at 6 weeks, measured by parental report of symptoms using the SDB Score.
RESULTS
A total of 276 participants (mean [SD] age, 6.1 [2.3] years; 146 male individuals [53%]) were recruited, 138 in each treatment arm. Resolution of significant SDB symptoms occurred in 56 of 127 participants (44%) in the mometasone group and 50 of 123 participants (41%) in the saline group (risk difference, 4%; 95% CI, -8% to 16%; P = .51) with 26 participants lost to follow-up and missing values managed by multiple imputation. The main adverse effects were epistaxis, affecting 12 of 124 participants (9.7%) in the mometasone group and 18 of 120 participants (15%) in the saline group, and nasal itch/irritation, affecting 12 of 124 participants (9.7%) in the mometasone group and 22 of 120 participants (18%) in the saline group.
CONCLUSIONS AND RELEVANCE
Results of this randomized clinical trial suggest that there was no difference in treatment effect between intranasal mometasone and saline for the management of SDB symptoms. The results suggest that almost one-half of children with SDB could be initially managed in the primary care setting and may not require referral to specialist services, as is currently recommended.

Review
INTRODUCTION
The influence of mometasone furoate for paediatric asthma remains controversial.
AIM
We conducted a systematic review and meta-analysis to explore the efficacy and safety of mometasone furoate for paediatric asthma.
MATERIAL AND METHODS
We have searched PubMed, Embase, Web of science, EBSCO, and Cochrane library databases through October 2019 for randomized controlled trials assessing the effect of mometasone furoate versus placebo for paediatric asthma. This meta-analysis was performed using the random-effects model.
RESULTS
Four RCTs were included in the meta-analysis. Overall, as compared to placebo for paediatric asthma, mometasone furoate is associated with substantially increased predicted forced expiratory volume in 1 s (FEV) (mean difference (MD) = 7.53; 95% CI: 7.02-8.04; < 0.00001), FEV (MD = 0.11; 95% CI: 0.10-0.12; < 0.00001), and morning peak expiratory flow (AM PEF) (MD = 17.70; 95% CI: 9.91-25.49; < 0.00001), but demonstrates no obvious effect on pharyngitis (RR = 0.96; 95% CI: 0.59-1.58; = 0.89), upper respiratory tract infections (RR = 0.73; 95% CI: 0.50-1.05; = 0.09), or adverse events (RR = 1.05; 95% CI: 0.84-1.31; = 0.69).
CONCLUSIONS
Mometasone furoate may be effective and safe for paediatric asthma.

Tight junction defects (TJ) have been associated with a defective epithelial barrier function in allergic rhinitis (AR). Intranasal corticosteroids are potent drugs frequently used to treat AR and are shown to restore epithelial integrity by acting on TJs and by reducing type 2 cytokine production. However, the effect of different classes of intranasal corticosteroids on the epithelial barrier has not been studied. Therefore, we compared the effect of 2 intranasal corticosteroids, ie, fluticasone furoate (FF) and mometasone furoate (MF) on epithelial barrier function. Both FF and MF similarly increased trans-epithelial electrical resistance of primary nasal epithelial cell cultures from AR patients. In a house dust mite-induced allergic asthma mouse model, FF and MF had similar beneficial effects on fluorescein isothiocyanate-dextran 4 kDa mucosal permeability, eosinophilic infiltration and IL-13 levels. Both molecules increased mRNA expression of the TJ proteins occludin and zonula occludens-1, thereby restoring epithelial barrier function. Lastly, we showed that long-term FF treatment also increased expression of occludin in AR patients compared to controls. In conclusion, both FF and MF effectively restore epithelial barrier function by increasing expression of TJ proteins in AR patients.

Review
Dose bridging data for mometasone furoate in once-daily fixed-dose inhaled combinations of mometasone furoate/indacaterol and mometasone furoate/ indacaterol/glycopyrronium in patients with asthma.
Once-daily (o.d.) fixed-dose combinations of mometasone furoate/indacaterol acetate (MF/IND) and mometasone furoate/indacaterol acetate/glycopyrronium bromide (MF/IND/GLY), both delivered via the Breezhaler® device, are approved for the maintenance treatment of asthma. Across these fixed-dose combinations, while the doses of bronchodilators remain the same, the nominal doses of mometasone furoate in micrograms differ. This article presents the steps followed in bridging the mometasone furoate doses at the corresponding dose strengths in the mometasone furoate formulation delivered via the Twisthaler® and mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glycopyrronium bromide formulations delivered via the Breezhaler®. These were: (i) bridging the mometasone furoate doses in the Twisthaler® (previously approved) to mometasone furoate doses in the Breezhaler®; (ii) bridging the mometasone furoate doses in the Breezhaler® to mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glycopyrronium bromide formulation. Following this stepwise approach, it was determined that mometasone furoate 80 μg o.d. (medium-dose strength) and 160 μg o.d. (high-dose strength) in mometasone furoate/indacaterol acetate/glycopyrronium bromide formulation provided comparable inhaled corticosteroid efficacy to mometasone furoate 160 μg o.d. (medium-dose strength) and 320 μg o.d. (high-dose strength) in the mometasone furoate/indacaterol acetate formulation, respectively. These doses were used in the PLATINUM Phase III clinical program that investigated the efficacy and safety of mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glycopyrronium bromide combinations in patients with asthma.

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.

Annals of Allergy, Asthma & Immunology... Nov 2022GSP301 nasal spray is a fixed-dose combination of the antihistamine olopatadine hydrochloride and the corticosteroid mometasone furoate. (Randomized Controlled Trial)
Randomized Controlled Trial
BACKGROUND
GSP301 nasal spray is a fixed-dose combination of the antihistamine olopatadine hydrochloride and the corticosteroid mometasone furoate.
OBJECTIVE
To evaluate the efficacy, safety, and tolerability of GSP301 in pediatric patients (aged ≥6 to <12 years) with seasonal allergic rhinitis (SAR).
METHODS
This double-blind, randomized, parallel-group study randomized 446 eligible patients 1:1 (GSP301 [olopatadine hydrochloride 665 μg and mometasone furoate 25 μg] or placebo) as 1 spray/each nostril twice daily for 14 days. The primary end point was change from baseline in average morning and evening subject-reported 12-hour reflective Total Nasal Symptom Score (rTNSS) over a 14-day treatment period analyzed using mixed-effect model repeated measures. Additional assessments included instantaneous Total Nasal Symptom Score, Pediatric Rhinoconjunctivitis Quality of Life Questionnaire, reflective Total Ocular Symptoms Score, instantaneous Total Ocular Symptoms Score, individual symptoms, Physician-assessed Nasal Symptom Score, and adverse events.
RESULTS
GSP301 showed clinically meaningful and statistically significant improvement in rTNSS vs placebo (-0.6; 95% confidence interval, -0.9 to -0.2; P = .001). Statistically significant improvements favoring GSP301 were shown for all individual rTNSS symptoms, instantaneous Total Nasal Symptom Score, and most of its individual symptoms, Physician-assessed Nasal Symptom Score (P = .01), and Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (P < .001). For ocular symptoms, numerical improvements favoring GSP301 were observed, with statistical significance achieved only for reflective "tearing/watering eyes" (P = .04). Treatment-emergent adverse events occurred in 12.0% and 10.4% of patients in the GSP301 and placebo groups, respectively. One subject (0.5%) (placebo group) experienced a serious adverse event (suspected viral meningitis) that was not related to the study treatment and was resolved.
CONCLUSION
GSP301 was well tolerated and efficacious for treating SAR symptoms in pediatric patients and showed a favorable safety profile.

BACKGROUND
In order to evaluate the efficacy of intranasal mometasone furoate in patients with non-allergic rhinitis (NAR), a real-life, observational, prospective study is performed.
METHODS
Thirty-one patients (age 18-64 years) receive intranasal (mometasone furoate, 200 µg b.i.d. for 15 consecutive days per month for 6 consecutive months), plus isotonic nasal saline. The cytologic pattern of local inflammation, nasal airflow, through peak nasal inspiratory flow (PNIF), quality of life (QoL), through the rhinitis quality of life questionnaire (RQLQ), the sinonasal outcome test (SNOT-22), the short-form 36-item health survey (SF-36v2), and the combined symptom medication score (CSMS), and, finally, olfactory function, through Sniffin' sticks-16 identification test (SSIT-16), are evaluated at baseline and after treatment.
RESULTS
NARNE is the most frequent cytological pattern (48% of the total sample). The therapeutic response shows improvement in olfactory function and QoL.
CONCLUSIONS
The results of this study confirm that intranasal mometasone furoate is an effective treatment for patients with NAR.

Randomized Controlled Trial
BACKGROUND
QMF149 is an inhaled fixed-dose combination of indacaterol acetate and mometasone furoate (MF) delivered via Breezhaler®, under development for once-daily treatment of asthma. MF delivered via Twisthaler® is approved as Asmanex® Twisthaler® for the treatment of asthma. Bridging of MF delivered via Twisthaler® to MF delivered via Breezhaler® was undertaken as part of QMF149 development to enable dose comparisons between the devices. Pharmacokinetics (PK) of MF were characterized in two studies; a single dose PK study in healthy volunteers and a pharmacokinetic/pharmacodynamic (PK/PD) study in asthma patients.
OBJECTIVES
The PK study in healthy volunteers evaluated the PK of single doses of MF via Breezhaler® (50-400 μg) and compared systemic exposure of MF following administration via Breezhaler® and Twisthaler® 400 μg (2 inhalations of 200 μg). The study in patients with asthma characterized the MF PK profile following once-daily inhalation of MF via Breezhaler® and Twisthaler® devices for 4 weeks.
METHODS
In the open-label, single-dose, crossover study, healthy subjects sequentially received MF via Twisthaler® (400 μg, medium-dose inhaled corticosteroid [ICS]) and escalating doses via Breezhaler® (50, 100, 200, 400 μg). PK data were obtained up to 72 h post-dose. In the double-blind, double-dummy, parallel-group study, asthma patients were randomised to receive either MF 80 μg (low-dose ICS) or 320 μg (high-dose ICS) via Breezhaler®, or 200 μg (low-dose ICS) or 800 μg (2 inhalations of 400 μg; high-dose ICS) via Twisthaler® once daily for 4 weeks. PK sampling was performed on Days 1 and 28 at pre-dose and up to 24 h post-dose.
RESULTS
In the healthy volunteer PK study, 20 healthy subjects completed all treatments. Dose-normalised AUC of MF was 1.8-1.9-fold higher when delivered via Breezhaler® versus Twisthaler®. AUC and C of MF increased in a dose-proportional manner over the range of 50-400 μg via Breezhaler®. Results from this study guided dose selection of MF via Breezhaler® for the asthma study. In the asthma study, in a subset of 96 patients, mean systemic exposure (AUC and C) for MF 80 and 320 μg via Breezhaler® was comparable with MF 200 and 800 μg via Twisthaler®, respectively, on Day 28.
CONCLUSION
PK characterization in a healthy volunteer PK study and subsequently an asthma study enabled selection of 80 μg (low), 160 μg (medium), and 320 μg (high) delivered via Breezhaler® as MF doses comparable to the 200 μg, 400 μg and 800 μg doses delivered by Twisthaler®, respectively, as part of QMF149 formulation development.

Mometasone furoate (MF) is a medium-potency synthetic glucocorticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. However, its role in the treatment of ocular inflammation has not yet been explored. This work investigated the anti-inflammatory activity of MF in ocular tissues. First, the in vivo safety of the intravitreal (IVT) injection of MF (80, 160, and 240 µg) was evaluated via clinical examination (including the assessment of intraocular pressure), electroretinography (ERG), and histopathology. Second, MF was tested in an experimental model of bacillus Calmette-Guérin (BCG)-induced uveitis in Wistar rats. Intraocular inflammation was then evaluated via a slit-lamp and fundus examination, ERG, histopathology, and the quantification of pro-inflammatory markers. Intravitreal MF showed no toxicity in all the investigated doses, with 160 µg leading to attenuated disease progression and improvement in clinical, morphological, and functional parameters. There was a significant reduction in the levels of inflammatory markers (myeloperoxidase, interleukins 6 and 1β, CXCL-1, and tumor necrosis factor-alpha) when compared to the levels in untreated animals. Therefore, MF should be further investigated as a promising drug for the treatment of ocular inflammation.
