Safety of a novel intranasal formulation of azelastine hydrochloride and fluticasone propionate in children: A randomized clinical trial.

ABSTRACT: BACKGROUND:The safety of a novel intranasal formulation of azelastine hydrochloride (AZE) and fluticasone propionate (FP) has been established in adults and adolescents with allergic rhinitis but not in children <12 years old. OBJECTIVE:To evaluate the safety and tolerability of an intranasal formulation of AZE and FP in children ages 4-11 years with allergic rhinitis. METHODS:The study was a randomized, 3-month, parallel-group, open-label design. Qualified patients were randomized in a 3:1 ratio to AZE/FP (n = 304) or fluticasone propionate (FP) (n = 101), one spray per nostril twice daily, and to one of three age groups: ?4 to <6 years, ?6 to <9 years, and ?9 to <12 years. Safety was assessed by child- or caregiver-reported adverse events, nasal examinations, vital signs, and laboratory assessments. RESULTS:The incidence of treatment-related adverse events (TRAEs) was low in both the AZE/FP (16%) and FP-only (12%) groups after 90 days' continuous use. Epistaxis was the most frequently reported TRAE in both groups (AZE/FP, 9%; FP, 9%), followed by headache (AZE/FP, 3%; FP, 1%). All other TRAEs in the AZE/FP group were reported by ?1% of the children. The majority of TRAEs were of mild intensity and resolved spontaneously. Results of nasal examinations showed an improvement over time in both groups, with no cases of mucosal ulceration or nasal septal perforation. There were no unusual or unexpected changes in laboratory parameters or vital signs. CONCLUSION:The intranasal formulation of AZE and FP was safe and well tolerated after 3 months' continuous use in children with allergic rhinitis.The study was registered on ClinicalTrials.gov (NCT01794741).

Project description:BackgroundThe combination of the antihistamine azelastine (AZE) with the corticosteroid fluticasone propionate (FP) in a single spray, has been reported to be significantly more effective at reducing allergic rhinitis (AR) symptoms than treatment with either corticosteroid or antihistamine monotherapy. However, the biological basis for enhanced symptom relief is not known. This study aimed to compare gene expression profiles (760 immune genes, performed with the NanoString nCounter) from peripheral blood and nasal brushing/lavage lysate samples in response to nasal spray treatment.MethodsModerate/severe persistent dust mite AR sufferers received either AZE (125 μg/spray) nasal spray (n = 16), FP (50 μg/spray) nasal spray (n = 14) or combination spray AZE/FP (125 μg AZE and 50 μg FP/spray) (n = 14) for 7 days, twice daily. Self-reported symptom questionnaires were completed daily for the study duration. Gene expression analysis (760 immune genes) was performed with the NanoString nCounter on purified RNA from peripheral blood and nasal brushing/lavage lysate samples.ResultsIn nasal samples, 206 genes were significantly differentially expressed following FP treatment; 182 genes downregulated (-2.57 to -0.45 Log2 fold change [FC]), 24 genes upregulated (0.49-1.40 Log2 FC). In response to AZE/FP, only 16 genes were significantly differentially expressed; 10 genes downregulated (-1.53 to -0.58 Log2 FC), six genes upregulated (1.07-1.62 Log2 FC). Following AZE treatment only five genes were significantly differentially expressed; one gene downregulated (-1.68 Log2 FC), four genes upregulated (0.59-1.19 Log2 FC). Immune gene changes in peripheral blood samples following treatment were minimal. AR symptoms improved under all treatments, but improvements were less pronounced following AZE treatment.ConclusionAZE/FP, FP, and AZE had diverse effects on immune gene expression profiles in nasal mucosa samples. The moderate number of genes modulated by AZE/FP indicates alternative pathways in reducing AR symptoms whilst avoiding extensive local immune suppression.

Project description:ObjectiveThe aims of this study were (1) to characterise the type of patient prescribed MP-AzeFlu (Dymista, a novel formulation of azelastine hydrochloride, fluticasone propionate and excipients in a single spray) in real life in the UK and physicians' reasons for prescribing it and (2) to quantify the personal and societal burden of allergic rhinitis (AR) in the UK prior to MP-AzeFlu prescription.Design, setting and participantsThis multicentre, non-interventional study enrolled patients (n=193) with moderate-to-severe AR and acute symptoms who were eligible to receive treatment with MP-AzeFlu according to its licensed indications. Information was gathered on patient demographics, AR history and symptom severity, symptomatology and AR treatments in the previous calendar year (prior to MP-AzeFlu prescription). Physicians also recorded the number of previous AR visits, specific reasons for these visits and their reason for prescribing MP-AzeFlu.ResultsMost patients had seasonal AR either alone (10.4%) or in combination with perennial AR (35.2%), but many had AR of unknown origin (35.8%). Prior to MP-AzeFlu prescription, patients reported troublesome symptoms (78.2%) and sleep disturbance (64.8%), with congestion considered the most bothersome (54.4%) and ocular symptoms reported by 68.4% of patients. The most frequent reason for MP-AzeFlu prescription was that other therapies were not sufficient in the past (78.8%) or not sufficient to treat acute symptoms (16.1%). 79.3% of patients reported using ?2 AR therapies in the past year. An average of 1.6 (SD 1.9) doctor visits due to AR were reported prior to MP-AzeFlu prescription.ConclusionsIn the UK, MP-AzeFlu was prescribed for individuals (?12?years) with moderate/severe AR irrespective of (1) previous AR treatment (mono or multiple), (2) previous or likely treatment failure, (3) phenotype, (4) number of previous physician visits for AR and (5) for the relief of both acute symptoms and in anticipation of allergen exposure.

Project description:BackgroundThe efficacy and safety of fluticasone propionate/formoterol fumarate pressurized metered-dose inhaler (pMDI) (fluticasone/formoterol; Flutiform®; 100/10 µg b.i.d.) was compared with fluticasone propionate (Flixotide® Evohaler® pMDI; 100 µg b.i.d.) and fluticasone/salmeterol (Seretide® Evohaler® pMDI; 100/50 µg b.i.d.) in a pediatric asthma population (EudraCT number: 2010-024635-16).MethodsA double-blind, double-dummy, parallel group, multicenter study. Patients, aged 5-<12 years with persistent asthma ⩾ 6 months and forced expiratory volume in 1 s (FEV1) ⩽ 90% predicted were randomized 1:1:1 to 12 weeks' treatment. The study objectives were to demonstrate superiority of fluticasone/formoterol to fluticasone and non-inferiority to fluticasone/salmeterol.ResultsA total of 512 patients were randomized: fluticasone/formoterol, 169; fluticasone, 173; fluticasone/salmeterol, 170. Fluticasone/formoterol was superior to fluticasone for the primary endpoint: change from predose FEV1 at baseline to 2 h postdose FEV1 over 12 weeks [least squares (LS) mean difference 0.07 l; 95% confidence interval (CI) 0.03, 0.11; p < 0.001] and the first key secondary endpoint, FEV1 area under the curve over 4 hours (AUC0-4 h) at week 12 (LS mean difference 0.09 l; 95% CI: 0.04, 0.13; p < 0.001). Per a prespecified non-inferiority margin of -0.1 l, fluticasone/formoterol was non-inferior to fluticasone/salmeterol for the primary endpoint (LS mean difference 0.00 l; 95% CI -0.04, 0.04; p < 0.001) and first key secondary endpoint (LS mean difference 0.01; 95% CI -0.03, 0.06; p < 0.001). Fluticasone/formoterol was non-inferior to fluticasone/salmeterol for the second key secondary endpoint, change from predose FEV1 over 12 weeks (treatment difference -0.02 l; 95% CI -0.06, 0.02; p < 0.001), but was not superior to fluticasone for this endpoint (LS mean difference 0.03 l; 95% CI -0.01, 0.07; p = 0.091). All treatments elicited large improvements from baseline to week 12 for the Pediatric Asthma Quality of Life Questionnaire (LS mean change 0.76 to 0.85 units) and Asthma Control Questionnaire (LS mean change -1.03 to -1.13 units). Few severe exacerbations were seen (fluticasone/formoterol: two; fluticasone/salmeterol: two). All treatments were well tolerated.ConclusionsThis study supports the efficacy and safety of fluticasone/formoterol in a pediatric asthma population and its superiority to fluticasone.

Project description:What is already known about this subject• The topical second generation anti-histamine azelastine hydrochloride (AZE) and the potent corticosteroid fluticasone propionate (FP) are well established first-line treatments in allergic rhinitis (AR). • MP29-02, a novel intranasal AZE and FP formulation, has been shown to control AR symptoms faster and better than standard intranasal AZE or FP. • The systemic bioavailabilities of marketed AZE and FP nasal spray products have been established at about 40% and 1% only, respectively. • For new combination medicinal products such as MP29-02, the determination of possible pharmacokinetic (PK) drug-drug interactions between both active components and formulation-based bioavailability alterations is essential.What this study adds• This paper provides for the first time information on potential drug-drug interactions, AZE and FP bioavailability and disposition characteristics of each component administered by the novel nasal spray formulation MP29-02. • The studies employed highly sensitive FP and AZE LC-MS/MS assays and could therefore be conducted with recommended therapeutic doses, thereby circumventing previously recognized draw-backs that required nasal bioavailability studies to be conducted using supra-therapeutic doses. • No significant PK drug-drug interaction between the active components AZE and FP was noted for MP29-02. • AZE bioavailabilty was equivalent when MP29-02 data were compared with MP29-02-AZE-mono and Astelin®. • Increased FP exposure was observed with MP29-02-based products compared with FP-BI. FP serum concentrations were generally very low with all investigational products suggesting no clinically meaningful pharmacodynamic differences in terms of systemic safety.Aim(s)To determine azelastine hydrochloride (AZE) and fluticasone propionate (FP) bioavailabilities of the novel nasal spray combination product MP 29-02, compared with MP29-02-based products containing only AZE (MP29-02-AZE-mono), FP (MP29-02-FP-mono), marketed AZE and FP single entity products (Astelin® and FP Boehringer-Ingelheim; FP-BI).MethodsTwo randomized, three period, six sequence, three treatment crossover studies were conducted in healthy subjects. Study 1 administered 200 µg FP as MP29-02, MP29-02-FP-mono or FP-BI. Study 2 administered 548 µg AZE as MP29-02, MP29-02-AZE-mono or Astelin®. Each dose consisted of two sprays/nostril. Serum FP and plasma AZE were followed over 24 (FP) and 120 h (AZE) and quantified by LC-MS/MS. Peak (C(max) ) and total exposures AUC(0,t(last) ) were compared between the treatments by anova.ResultsStudy 1: Average FP C(max) was very low with all products (≤ 10 pg ml(-1) ). FP AUC(0,t(last) ) point estimates (90% CIs) for MP29-02 : MP29-02-FP-mono and MP29-02 : FP-BI ratios (%) were 93.6 (83.6, 104.7) and 161.1 (137.1, 189.3). Corresponding ratios for C(max) were 91.0 (82.5, 100.4) and 157.4 (132.5, 187.1). Study 2: AZE AUC(0,t(last) ) point estimates (90% CIs) for MP29-02 : MP29-02-AZE-mono and MP29-02 : Astelin® ratios (%) were 98.8 (91.0, 107.4) and 105.5 (95.6, 116.4). Corresponding outcomes for C(max) were 102.7 (92.1, 114.4) and 107.3 (92.6, 124.3).ConclusionsNo interactions of AZE and FP were found with the MP29-02 formulation. Azelastine bioavailability was similar for MP29-02 and Astelin®. Maximum and total FP exposure was higher for MP29-02-based products compared with FP-BI. FP concentrations were generally very low with all investigational products and did not suggest clinically meaningful differences concerning systemic safety.
