Once-daily evening dosing of mometasone furoate administered via a dry powder inhaler does not adversely affect the hypothalamic-pituitary-adrenal axis

Combination of mometasone furoate and oxymetazoline for the treatment of adenoid hypertrophy concomitant with allergic rhinitis: A randomized controlled trial

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.

Impact of study design on the evaluation of inhaled and intranasal corticosteroids' effect on hypothalamic-pituitary-adrenal axis function

In part I of this review, an overview of the designs of hypothalamic-pituitary-adrenal (HPA) axis studies in the setting of inhaled corticosteroids (ICS) or intranasal corticosteroids (INS) use was discussed. Part II provides detailed discussion on the HPA axis evaluation results for each common ICS and INS, and how these results are possibly affected by the factors of study design. Significant adrenal suppression at conventional ICS/INS doses appears to be rare in clinical settings. The magnitude of cortisol suppression varies widely among different study designs. Factors potentially impacting this variability include: the choice of dose, dosing duration, assay sensitivity, statistical methodology, study population, and compliance. All of these factors have the potential to affect the extent of HPA axis effects detected and should be considered when designing or interpreting the results of a HPA axis study.

Hypothalamic-pituitary-adrenal axis effects of mometasone furoate/formoterol fumarate vs fluticasone propionate/salmeterol administered through metered-dose inhaler

BACKGROUND

The effects of mometasone furoate and fluticasone propionate on the hypothalamic-pituitary-adrenal axis were compared when administered from combination metered-dose inhaler (MDI) products.

METHODS

In a randomized, open-label, placebo-controlled, parallel group study, 66 patients with mild to moderate asthma received one of the following four treatments bid through an MDI for 42 days: mometasone furoate/formoterol (MF/F) 200 μg/10 μg, MF/F 400 μg/10 μg, fluticasone propionate/salmeterol (FP/S) 460 μg/42 μg, or placebo. Plasma cortisol concentrations were measured over 24 h on days -1 (baseline) and 42. Geometric mean ratio (GMR) and 90% CI for mean change from baseline to day 42 in 24-h plasma cortisol area under the curve (AUC) were calculated for each treatment. If the 90% CI for the GMRs fell within 70% to 143%, treatments were deemed comparable.

RESULTS

Mean baseline cortisol AUCs were similar across groups. Mean cortisol effects (change from baseline) were similar for MF/F 400 μg/10 μg and FP/S 460 μg/42 μg (GMR, 119%; 90% CI, 101%-140%). Effects of MF/F 200 μg/10 μg on cortisol AUC were similar to placebo (GMR, 92%; 90% CI, 78%-110%), whereas MF/F 400 μg/10 μg and FP/S 460 μg/42 μg lowered cortisol AUC vs placebo (GMR, 78% [90% CI, 66%-92%] and 66% [90% CI 56%-78%], respectively). All treatments were generally well tolerated.

CONCLUSIONS

MF/F 400 μg/10 μg or FP/S 460 μg/42 μg bid through an MDI led to similar reductions from baseline in mean cortisol AUC (22% and 34% lower than placebo, respectively), whereas the effect of MF/F 200 μg/10 μg was similar to placebo.

Impact of study design on the evaluation of inhaled and intranasal corticosteroids' effect on hypothalamic-pituitary-adrenal axis function, part I: general overview of HPA axis study design

Inhaled and intranasal corticosteroids (ICS and INS) are among the mainstays of the treatment for asthma and allergic rhinitis, respectively, and also carry the potential to suppress the hypothalamic-pituitary-adrenal (HPA) axis. Several important factors affect the interpretability of trials investigating the impact of ICS and INS on the HPA axis. This paper reviews 106 published clinical trials, peer-reviewed articles, and New Drug Application reviews of approved ICS and INS, using MEDLINE and Drugs@FDA database. The trials included in this review evaluated the potential impact on HPA axis function of eight approved single-ingredient ICS and INS (beclomethasone dipropionate, budesonide, ciclesonide, flunisolide, fluticasone furoate, flucticasone propionate, mometasone furoate, and triamcinolone acetonide) and combination products containing these ingredients. The most commonly utilized design was blinded, placebo controlled, and short term (<6 weeks) for adult trials and blinded, placebo controlled, and long term (≥6 weeks) for pediatric trials. Factors potentially affecting trial results include the choice of dose, dosing duration, assay sensitivity, statistical methodology, and the study population evaluated (patients or healthy volunteers). All of these factors have the potential to affect the level of adrenal suppression detected. In conclusion, to be informative, a HPA axis study should be well designed and carefully implemented to minimize variability in results and improve the overall interpretability of data obtained.

Efficacy and safety profile of fluticasone furoate administered once daily in the morning or evening: a randomized, double-blind, double-dummy, placebo-controlled trial in adult and adolescent patients with persistent bronchial asthma

BACKGROUND

Fluticasone furoate (FF) is an inhaled corticosteroid that is structurally and functionally distinct from fluticasone propionate and is under development as a once-daily therapy for asthma.

OBJECTIVE

The objective of this study was to estimate the treatment differences (with 95% CI) in efficacy and safety profile between FF administered once daily in the morning and evening via Rotadisk Diskhaler (see text) in patients with persistent asthma. No hypothesis testing was performed for this comparison.

METHODS

This was a randomized, double-blind, double-dummy, placebo-controlled, parallel-group study. Patients (ages 16-55 years; peak expiratory flow [PEF] 50%-90% predicted) were randomized to receive 1 of 3 doses of FF Rotadisk or placebo daily for 4 weeks. The sponsor, GlaxoSmithKline, designed the study and selected the study sites. The primary end point was change from baseline in daily trough (pretreatment, prebronchodilator) PEF during the treatment period with FF Rotadisk 100 μg once daily in the morning compared with 100 μg once daily in the evening. Other end points included change from baseline in forced expiratory volume in 1 second, asthma symptom score, adverse events (AEs), 24-hour urinary cortisol excretion, and FF pharmacokinetics.

RESULTS

Five hundred and seventy-five patients (mean age 36.6 years, 56.9% female) formed the intent-to-treat population and were randomly allocated to FF Rotadisk 100 μg once daily in the morning (n = 144), FF Rotadisk 100 μg once daily in the evening (n = 146), FF Rotadisk 250 μg once daily in the evening (n = 142), or placebo (n = 143). Of these patients, 526 (91.5%) completed the study. A smaller proportion of patients in the placebo group (86.7%) than in the active treatment groups completed the study. Mean difference in PEF change from baseline with FF Rotadisk 100 μg once daily in the morning relative to evening was +13.4 L/min (95% CI, 2.3-24.4). However, morning trough values might have been affected by higher placebo response after morning dosing (18.8 vs 8.8 L/min). Trough PEF improved relative to placebo (P ≤ 0.005), with little difference between FF Rotadisk 100 μg morning (19 L/min) and evening (16 L/min) dosing, as with other efficacy measures. Frequencies of all-cause AEs were similar with FF Rotadisk (32%-39%, 2 serious AEs) and placebo (37%, 1 serious AE). No serious AEs were deemed by the investigator to be related to study treatment. Twenty-four-hour urinary cortisol increased from baseline in all groups, but the increase was significantly lower with FF Rotadisk 250 μg group than placebo.

CONCLUSION

FF Rotadisk administered once daily in the morning or evening was well tolerated and associated with improvements in lung function and asthma symptoms compared with placebo. Improvements seen for FF Rotadisk 100 μg appear to be comparable for morning and evening dosing. Clinical.trials.govNCT01499446.

Efficacy in asthma of once-daily treatment with fluticasone furoate: a randomized, placebo-controlled trial

Background

Fluticasone furoate (FF) is a novel long-acting inhaled corticosteroid (ICS). This double-blind, placebo-controlled randomized study evaluated the efficacy and safety of FF 200 mcg or 400 mcg once daily, either in the morning or in the evening, and FF 200 mcg twice daily (morning and evening), for 8 weeks in patients with persistent asthma.

Methods

Asthma patients maintained on ICS for ≥ 3 months with baseline morning forced expiratory volume in one second (FEV₁) 50-80% of predicted normal value and FEV₁ reversibility of ≥ 12% and ≥ 200 ml were eligible. The primary endpoint was mean change from baseline FEV₁ at week 8 in pre-dose (morning or evening [depending on regimen], pre-rescue bronchodilator) FEV₁.

Results

A total of 545 patients received one of five FF treatment groups and 101 patients received placebo (intent-to-treat population). Each of the five FF treatment groups produced a statistically significant improvement in pre-dose FEV₁ compared with placebo (p < 0.05). FF 400 mcg once daily in the evening and FF 200 mcg twice daily produced similar placebo-adjusted improvements in evening pre-dose FEV₁ at week 8 (240 ml vs. 235 ml). FF 400 mcg once daily in the morning, although effective, resulted in a smaller improvement in morning pre-dose FEV₁ than FF 200 mcg twice daily at week 8 (315 ml vs. 202 ml). The incidence of oral candidiasis was low (0-4%) and UC excretion was comparable with placebo for all FF groups.

Conclusions

FF at total daily doses of 200 mcg or 400 mcg was significantly more effective than placebo. FF 400 mcg once daily in the evening had similar efficacy to FF 200 mcg twice daily and all FF regimens had a safety tolerability profile generally similar to placebo. This indicates that inhaled FF is an effective and well tolerated once-daily treatment for mild-to-moderate asthma.
