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

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.

Safety of house dust mite sublingual immunotherapy standardized quality tablet in children allergic to house dust mites.

Background: Sublingual immunotherapy (SLIT) tablets could be an important alternative to subcutaneous immunotherapy for house dust mite (HDM) allergy in children.

Objective: To characterize the safety, tolerability, and duration of local adverse events (AEs) of an HDM SLIT tablet (MK-8237; Merck, ALK Abellò, and Torii) in North American children 12 to 17 years old with HDM allergic rhinitis with and without conjunctivitis and with or without asthma.

Methods: In this phase 1, multicenter, double-blinded, randomized trial (NCT01678807), children received placebo, HDM SLIT tablet 6 standardized quality (SQ) HDM, or 12 SQ-HDM once daily for 28 days.

Intranasal triamcinolone and growth velocity.

Background: Inadequate designs and conflicting results from previous studies prompted the US Food and Drug Administration to publish guidelines for the design of clinical trials evaluating the effects of orally inhaled and intranasal corticosteroids on the growth of children. This study conformed to these guidelines to evaluate the effect of triamcinolone acetonide aqueous nasal spray (TAA-AQ) on the growth of children with perennial allergic rhinitis (PAR).

Methods: This randomized, double-blind, placebo-controlled, parallel-group, multicenter study evaluated the effect of once-daily TAA-AQ (110 μg) on the growth velocity (GV) of children aged 3-9 years with PAR by using stadiometry at baseline (4-6 months), during treatment (12 months), and at follow-up (2 months).

A phase 3 trial assessing the efficacy and safety of grass allergy immunotherapy tablet in subjects with grass pollen-induced allergic rhinitis with or without conjunctivitis, with or without asthma.

Background: Design and execution of immunotherapy trials for seasonal allergies may be complicated by numerous factors including variable allergy testing methods, pollen levels, and timing and intensity of other seasonal allergens. We evaluated grass allergy immunotherapy tablet (AIT) treatment in North American adults with grass pollen-induced allergic rhinitis with or without conjunctivitis (AR/C), with/without asthma.

Methods: Subjects age 18-65 with clinical history of grass pollen-induced AR/C, with/without asthma were randomized 1:1 to once-daily 2800 BAU Timothy grass AIT (oral lyophilisate, Phleum pratense, 75,000 SQ-T, containing approximately 15 μg of Phl p 5) or placebo.

Randomized controlled trial of ragweed allergy immunotherapy tablet efficacy and safety in North American adults.

Background: Ragweed is an important cause of allergic rhinitis with or without conjunctivitis (AR/C) in North America and elsewhere. Allergen immunotherapy enabling safe patient self-administration is considered an unmet clinical need. Allergy immunotherapy tablet (AIT) treatment has shown promising efficacy and safety for grass allergy but has not been assessed for ragweed allergy.
