Mometasone furoate nasal spray for moderate-to-severe nasal congestion in subjects with seasonal allergic rhinitis.

Nasal congestion is a frequent, bothersome symptom of seasonal allergic rhinitis (SAR). Mometasone furoate nasal spray (MFNS) has established efficacy in treating nasal allergy symptoms, but no study has been conducted with the primary purpose of evaluating MFNS for relief of congestion. This study assessed MFNS for congestion and other nasal symptoms in SAR. Two double-blind, placebo-controlled studies randomized symptomatic SAR patients to 15 days of MFNS, 200 micrograms, or placebo q.d. each morning. Participants scored individual components of total nasal symptom score (TNSS; congestion, rhinorrhea, sneezing, and itching) on a 4-point scale in the morning (A.M.) and evening (P.M.). Symptoms were scored for the time of assessment (NOW) and for the previous 12 hours (PRIOR). The pooled population comprised 684 patients randomized to MFNS (n = 344) or placebo (n = 340). Change from baseline in A.M./P.M. PRIOR nasal congestion score averaged over days 1-15, the primary end point, was significantly (p < 0.001) greater with MFNS than with placebo (0.68-point [25.2%] reduction versus 0.45-point [16.0%] reduction, respectively). Reduction in A.M./P.M. PRIOR TNSS averaged over days 1-15, a key secondary end point, was also superior with MFNS (2.83 points [28.5%] versus 1.79 points [17.6%]; p < 0.001). Predose A.M. NOW congestion, other nasal symptoms, and TNSS improved significantly more with MFNS, indicating 24-hour efficacy. Adverse events were infrequent and localized; the most common (epistaxis and pharyngolaryngeal pain) occurred in 1.0% of MFNS patients. MFNS q.d. provides sustained relief for nasal congestion and other SAR symptoms.

Bronchodilation with mometasone furoate/formoterol fumarate administered by metered-dose inhaler with and without a spacer in children with persistent asthma.

BACKGROUND: The bronchodilatory effect of mometasone furoate/formoterol fumarate (MF/F) administered by metered-dose inhaler (MDI) with or without a spacer has not been evaluated previously in children aged 5-11 years. METHODS: This was a randomized, multicenter, placebo-controlled, single-dose, four-period crossover study. Children with persistent asthma aged 5-11 years participated in this study. Subjects used inhaled corticosteroids with/without long-acting beta-2 agonists for 12 weeks before enrollment and at screening had forced expiratory volume in 1 sec (FEV1 ) ≥70% predicted. Subjects received MF/F MDI 100/10 µg with/without spacer (AeroChamber Plus® with Flow-Vu® Anti-Static Valved Holding Chamber), F-Dry Powder Inhaler (F-DPI) 10 µg, and placebo MDI with/without spacer in separate treatment periods. The primary endpoint was FEV1 area under the curve from 0 to 12 hr (AUC0-12hr ) for the comparison of MF/F with spacer versus placebo. Secondary measurements included MF/F without spacer versus placebo, as well as MF/F with spacer versus MF/F without spacer, and F-DPI versus placebo. Analysis was performed with an analysis of covariance model for a crossover study. RESULTS: Data from 87 subjects were analyzed. MF/F with spacer demonstrated a larger change in mean FEV1 AUC0-12hr versus placebo (115 vs. -9 mL), with a treatment difference of 124 mL (95% CI 94-154, P < 0.001). Similarly, MF/F without spacer versus placebo resulted in a 102 mL difference in mean-adjusted FEV1 AUC0-12hr (95% CI 73-131, P < 0.001), whereas the difference between MF/F with spacer versus MF/F without spacer was 22 mL (95% CI -8 to 52, P = 0.144). The difference between F-DPI versus placebo was 106 mL (95% CI 77-135, P < 0.001). No unexpected adverse events were observed. CONCLUSIONS: In this trial, MF/F MDI 100/10 µg demonstrated significant bronchodilation in children aged 5-11 years regardless of the use of a spacer. No difference in bronchodilation was observed between MF/F MDI and F-DPI.

Mometasone furoate nasal spray plus oxymetazoline nasal spray: short-term efficacy and safety in seasonal allergic rhinitis.

BACKGROUND: Allergic rhinitis (AR) and associated congestion adversely affect patients' lives. The intranasal corticosteroid mometasone furoate nasal spray (MFNS) is effective for AR symptoms including nasal congestion, and the intranasal decongestant oxymetazoline (OXY) is effective against nasal congestion, but the combination has not been fully studied. This study was designed to assess the efficacy of the combination of MFNS and OXY for the relief of seasonal allergic rhinitis (SAR) symptoms. METHODS: This phase 2 controlled clinical trial randomized adolescent and adult subjects (≥12 years; 2-year SAR) to MFNS q.d. (200 µg) + 3 sprays/nostril of OXY 0.05% (MFNS + OXY3); MFNS q.d. + 1 spray/nostril of OXY (MFNS + OXY1); MFNS q.d.; OXY b.i.d.; or placebo for 15 days, with 1-week follow-up. Coprimary end points were change from baseline in morning/evening (A.M./P.M.) instantaneous (NOW) total nasal symptom score (TNSS) over days 1-15 and AUC (AUC[0-4 hr]) change from baseline in day 1 congestion. RESULTS: In 705 subjects, both combinations reduced A.M./P.M. NOW TNSS over days 1-15 significantly more than OXY b.i.d. or placebo (p ≤ 0.002). Mean standardized AUC(0-4 hr) day 1 congestion change from baseline was significantly greater in combination and OXY b.i.d. groups (MFNS + OXY3, -0.92; MFNS + OXY1, -0.80; OXY b.i.d., -1.06) versus placebo (-0.57) and MFNS q.d. (-0.63). Combinations and MFNS q.d. were significantly effective for A.M./P.M. NOW TNSS over each weekly period; OXY b.i.d. was superior to placebo in week 1. Adverse events (AEs) were few and similar across treatments; one MFNS q.d. and one placebo subject experienced a serious AE, with neither considered treatment related. CONCLUSION: Combining MFNS with OXY relieves SAR symptoms, including congestion, with faster onset of action than MFNS q.d. and better sustained efficacy than OXY b.i.d.

Immunomodulatory effect of the antiasthma Chinese herbal formula MSSM-002 on TH2 cells.

BACKGROUND: T(H)2 cytokines play a central role in the pathogenesis of allergic asthma. We previously showed that the "antiasthma" Chinese herbal formula MSSM-002 exhibited therapeutic effects on established allergic airway responses in a murine model of allergic asthma. However, the mechanisms underlying these effects are largely unknown. OBJECTIVE: The objective of this study was to determine whether and how MSSM-002 modulates an established T(H)2 response and whether the actions of MSSM-002 on T(H)2 cell differs from corticosteroids. METHODS: T(H)2 polarized splenocytes (T(H)2-SPCs) from mice with antigen-induced airway hyperresponsiveness and T(H)2 cloned cells, D10 G4.1 (D10), were cultured in the presence or absence of antigen with or without MSSM-002 and dexamethasone, and the proliferative responses and cytokine profiles were determined. Apoptosis and T(H)2 transcription factor GATA-3 expression and binding to IL-4 gene promoter and V(A) enhancer in MSSM-002-treated D10 cells were also determined. RESULTS: MSSM-002 significantly decreased antigen-induced proliferation and IL-4 and IL-5 production but increased IFN-gamma production by T(H)2-SPCs, whereas dexamethasone suppressed IFN-gamma as well as IL-4 and IL-5. Anti-IL-12 antibody, although abrogating MSSM-002 induction of IFN-gamma, had no significant effect on MSSM-002 suppression of IL-4 and IL-5 secretion. MSSM-002 also suppressed T(H)2 cytokine secretion by D10 cells, and in contrast to dexamethasone, MSSM-002 did not induce apoptosis of D10 cells. MSSM-002 markedly suppressed GATA-3 mRNA and protein expression and the binding to IL-4 gene promoter and V(A) enhancer in D10 cells. CONCLUSION: MSSM-002, in contrast to the overall suppression of T cells by dexamethasone, exhibits immunomodulatory actions on T(H)2 cells caused, at least partially, by downregulation of GATA-3.
