Active clinical trials for "Rhinitis, Allergic"

Allergic rhinitis is a common illness suffered among US Veterans. There are medications that help relieve allergy symptoms, including nasal steroid sprays and antihistamines. Some patients have increase symptoms with exposure to their trigger, such as a grasses when combined with pollution due to oxidative stress from pollution. In this study, patients with allergic rhinitis to grass will be given broccoli sprout extract that contains an antioxidant sulforaphane do see if there is beneficial effect in these patients.

The purpose of this study was to demonstrate the efficacy and safety of omalizumab compared with placebo, on top of SoC (anti-histamine and nasal corticosteroid) in adult and adolescent patients with severe Japanese cedar pollinosis, whose symptoms were inadequately controlled despite the current recommended therapies (nasal corticosteroids plus one or more medications out of anti-histamine, leukotriene receptor antagonist, or prostaglandin D2/thromboxane A2 receptor antagonist) in the previous 2 Japanese cedar pollen seasons.

Sphenopalatine ganglion (SPG)-acupuncture has been shown to exhibit distinct effects in treatment of nasal inflammatory disease. Investigators aimed to assess the effects of SPG acupuncture in patients with seasonal allergic rhinitis. The randomized, double-blind, controlled clinical trial enrolled participants with seasonal allergic rhinitis. Participants will be randomly assigned to either active SPG-acupuncture group or sham-acupuncture group. All participants will be provided four times of acupuncture in 4 weeks, and then follow-up of 4 week. Primary trial outcomes are change in symptoms and change in need for medication. The primary outcomes will be measured in baseline, week1, week2, week3, week4, week 6 and week 8. Secondary outcomes include the changes in nasal patency (nasal airway resistance and nasal cavity volume), exhaled nasal nitric oxide.The investigators also evaluate change in neuropeptides (substance P, vasoactive intestinal peptide,neuropeptide Y) and inflammatory cytokines (interleukin(IL)-4, IL-5, IL-8, IL-17a, IL-22, IL-25, interferon-γ, tumor necrosis factor-α, transforming growth factor(TGF)-β1, TGF-β2, TGF-β3,Chemokine, Eotaxin) in nasal secretions as secondary outcomes. The secondary outcomes will be measured in baseline, week1, week4 and week 8.

The purpose of this study is to assess the efficacy and safety of short ragweed pollen allergen extract (MK-3641, SCH 039641, RAGWITEK™) sublingual immunotherapy tablets in children aged 5 to 17 years with ragweed-induced allergic rhinitis/rhinoconjunctivitis with or without asthma. The primary hypothesis of this study is that administration of short ragweed pollen allergen extract sublingual immunotherapy tablets to children 5 to 17 years of age, compared with placebo, will result in a significant reduction in the combination of rhinoconjunctivitis symptoms and medication use over the peak ragweed season (RS).

The objective of this study was to assess the efficacy and safety of 12 months of treatment with 300 IR of STG320 sublingual tablets compared with placebo in adults and adolescents with HDM-associated allergic rhinitis.

To determine the effect of Montelukast in Asthma and Allergic rhinits patients

A single and multiple dose study to assess the safety of JNJ 38224342 compared to placebo in healthy volunteers and in volunteers with seasonal allergies.

The prevalence of allergic rhinitis is high and appears to be rising worldwide. Therefore, it is important and necessary to understand and visualize therapy effects on this disease. In this study we will demonstrate the effect of levocetirizine on nasal cavity dimensions by assessing not only standard nasal flow diagnostics such as rhinomanometry and acoustic rhinometry, but supplement exami¬nation procedures with long-term rhinometry and magnetic resonance imaging (MRI). With the aid of a virtual model and computer fluid dynamics, we are able to simulate nasal air flow and provide three-dimensional visualization of the computed flow. In previous trials ([Bachert], [deBlic], [Day] and [Deruaz]) it has been shown that allergic symptoms, especially nasal congestion, diminish significantly under treatment with levocetirizine. We will demonstrate this anti-obstructive effect by comparing the reaction to nasal allergen challenge before and after four-week treatment with levocetirizine.

The objective of this study is to assess the efficacy and safety of cluster immunotherapy with highly polymerized allergen extracts.

The purpose of the study is to determine whether VAK694 when combined with subcutaneous immunotherapy leads to long term immune tolerance to allergen in individuals with seasonal allergic rhinitis.
