Active clinical trials for "Rhinitis, Allergic, Seasonal"

This study will assess the treatment effect of montelukast versus placebo over a 2 week period in patients with seasonal allergic rhinitis. Loratadine is included in the study as an active comparator.

The purpose of this study is to evaluate the effect of four times a day treatment with nasal carbon dioxide in patients with Seasonal Allergic Rhinitis symptoms.

This study will evaluate the effect of montelukast compared to placebo in children during the spring allergic rhinitis season.

The trial is performed to asses efficacy and safety of a sublingual extract of a six grass pollen mixture

Allergic rhinitis is an inflammatory disorder of the upper airway that occurs following allergen exposure. The focus of this study, seasonal allergic rhinitis (SAR), is one type of allergic rhinitis that is triggered by the pollen from trees, grasses, and weeds. Commonly referred to as (hay fever), it is characterized by sneezing, nasal congestion and pruritus, rhinorrhea, and pruritic, watery, red eyes. The primary objective of this study is to compare the efficacy and safety of GW685698X 100mcg once daily (QD) aqueous nasal spray with vehicle placebo nasal spray in adult and adolescent subjects (12 years of age and older) with seasonal allergic rhinitis (SAR) caused by ragweed pollen.

The aim of this clinical trial is to show safety and efficacy of the allergoid preparation of birch pollen allergens in the treatment of birch allergic patients in a representative number of patients.

The purpose of this study is to investigate the safety and effectiveness of ciclesonide nasal spray as compared with placebo (inactive substance) nasal spray in relieving symptoms of perennial allergic rhinitis.

The objective of the study is to document the objective immunological effects of SLIT on the nasal mucosa. Better understanding of these immunological pathways, in which this widely practised clinical therapy is likely to work, can only benefit the overall outcome of this, more patient friendly, therapy and it will demonstrate the effects of SLIT on the allergic reaction, with objective parameters, in the nasal tissues showing it to be a true etiological treatment of allergy.

The objective of this study is to assess the effect of 'Eucerin AtopiControl LOTION' and 'Eucerin AtopiControl facial cream' on dermal symptoms in patients with Atopic Dermatitis (AD) after two 4 h challenges with grass pollen on two consecutive days. In addition, this clinical study with exposure of Dactyls glomerate-sensitized Patients with AD shall be used to compare the skin response with AD Patients not-sensitized to Dactylis glomerata to understand the specificity of the grass pollen exposure.

Intranasal corticosteroids are accepted as safe and effective first-line therapy for allergic rhinitis, especially in treatment of persistent symptoms. Budesonide, a non-halogenic glucocorticoid, is widely used in the management of inflammatory mucosal diseases like chronic obstructive pulmonary disease, asthma and allergic rhinitis. It is a highly fat-soluble substance with low water solubility and is presented as dispersion in marketed nasal sprays, like Rhinocort aqua 64. The maximum therapeutic efficacy of Rhinocort aqua is obtained after an application period of 7 to 14 days. In Budesolv, the solubility of budesonide is considerably increased suggesting that the same therapeutic efficacy can be reached with a lower dose. Better bioavailability of the dissolved drug promise an earlier onset of therapeutic efficacy. The current trial is undertaken to demonstrate these two effects. Subjects suffering from grass pollen allergic rhinitis will be challenged with grass pollen in a challenge chamber. Allergic subjects will be treated with two actuations (50 μl) of respective study treatment into each nostril once daily for 8 days. The total daily budesonide dose will be 40 μg per subject for Budesolv 10 and 256 μg per subject for Rhinocort® aqua 64. The primary objective of the study is to show non-inferiority of Budesolv 10 to Rhinocort® aqua 64. On day 8 grass pollen allergic patients will be challenged with grass pollen over a period of 6 hours and subjective nasal symptoms (congestion, sneezing, itching, rhinorrhea) as well as objective symptoms (nasal airflow, nasal secretion) will be assessed every 15 minutes. The second objective of the trial is to demonstrate an early on-set of therapeutic efficacy of Budesolv 10 compared to Rhinocort aqua. On day 1, grass pollen allergic patients will be challenged with grass pollen allergen in the challenge chamber over a period of 6 hours. After 1 hour 45 minutes, patients will receive their first dosage of the respective nasal spray treatment. During the 6 hour grass pollen challenge, subjective and objective endpoints will be measured every 15 minutes. To eliminate an individual bias based on expectations, the effect and onset of action is also compared to the effects of a suitable placebo. The same set of study participants will receive all three interventions in three consecutive treatment periods.
