Active clinical trials for "Rhinitis"

This was a crossover study designed to see if patients with seasonal allergy symptoms preferred Clarinex® or Allegra®. Patients were randomized to take 7 days of Clarinex or Allegra treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Allegra, the patient prefers more.

The purpose of the study is to assess the safety of the study drug, Patanase (Olopatadine Hydrochloride Nasal Spray 0.6%) compared to placebo (inactive substance) in children ages 2 to less than 6 who have a history of nasal allergies, and to assess the pharmcokinetics (study of the action of a drug in the body) in these children

Allergen challenge facilities have been utilized for many years in clinical drug trials studying onset of action, proof of concept, duration of action, and efficacy. Each facility has somewhat different design characteristics and pollen dispersal technologies. Facilities are located in disparate geographic areas and have populations of participants who are sensitized to allergens unique to that area. Therefore, facilities have operated as single sites with little effort to evaluate facility comparability or to attempt standardization across facilities. The purpose of this study is to compare the two sites and assess whether the sites are able to achieve similar symptom scores.

Using Oligonucleotide Chip Analysis, investigators compared gene expression levels in allergic rhinitis patients before and after a series of acupoint herbal plaster and Acupuncture treatment. In the first year, Twenty-three participants with persistent allergic rhinitis each received four acupoint herbal plaster treatments, applied using the moxibustion technique, and clinical outcomes were evaluated using the Rhinitis Quality of Life Questionnaire (RQLQ). Peripheral blood samples were analyzed using an ImmunoCAP Phadiatop test, and patients were classified as phadiatop (Ph)-positive or -negative. Microarray results were examined for genes that were differentially expressed between (1) Ph-positive and -negative patients treated with herbal paste; and (2) before and after herbal paste treatment in the Ph-positive patient group. In the second year, Twenty-seven participants with persistent allergic rhinitis each received four acupoint herbal plaster treatments and 8 courses of acupuncture treatment over 4 weeks in the same time.

In this study subjects self recorded nasal and ocular symptoms scores from exposure to ragweed pollen in an Allergen Challenge Chamber (ACC). This single site study of seasonal allergic rhinitis was designed to enroll up to 35 participants. These participants would be age 18-70, male and female, with a mixture of ethnic groups. The study would involve 2 phases: Screening and Exposure. In the Exposure phase, participants were exposed to pollen for up to 180 minutes.

About 45 million people in Europe have allergic rhinitis (hay fever) - inflammation of the nasal passages causing sneezing, runny nose, nasal congestion, itching and tearing of the eyes. In the United Kingdom (UK), seasonal hay fever due to grass pollen allergy accounts for approximately 7 times more doctors' appointments than asthma. The standard treatment for hay fever consists of treating the symptoms with a nasal spray and an antihistamine. However, in a survey taken in a UK general practice less than 40% of patients with hay fever reported good symptom control with this standard treatment. For those patients with hay fever whose symptoms are not well controlled by treatment with antihistamines and nasal sprays, subcutaneous immunotherapy (SCIT) - (monthly injections of a grass allergen extract for a period of 3-5 years) is an effective alternative, and is approved in the UK on a named patient basis. More recently, allergen immunotherapy tablets (AITs) have been developed, including grass pollen allergen tablets. These have been shown to be highly effective in the treatment of hay fever, with the additional benefit of being convenient for patients, given that they may be taken at home. Grazax® (manufactured by Allergologisk Laboratorium København (ALK)-Abello, Denmark) has UK and European Union (EU) license for use in the treatment of troublesome grass pollen induced hay fever. The aim of this research is to investigate the effects of the AIT treatment on the immune system over time - which changes are taking place and when in the course of treatment. This will provide insight into the complexities of the development of allergen-specific immune tolerance - how harmful allergic responses against innocuous substances such as grass pollen can be overridden.

This trial is an exploratory randomised, parallel-group, double-blind, placebo- controlled, national, single-centre trial. The trial will be initiated before 2013 grass pollen season and subjects will be randomised in September 2013 to receive active treatment (Grazax®) or placebo during 2 years. Placebo group will be treated 2 years with placebo and a third year with active therapy (Grazax®) and active group will continue the active treatment in the third year. In the last year, all placebo patients will be changed to active group and active and placebo patients will be informed about, but the trial will not be unblinded until the end of the third year and patients won´t know what treatment they were assigned to during the first 2 years.

This study is designed to investigate the efficacy of fluticasone propionate (FP) on ocular symptoms associated with allergic rhinitis (AR).

To assess the reproducibility of the allergic response in the cat allergic subjects, measured as the change from baseline of the Total Nasal Symptom Score (TNSS) on the two challenge days.

An open label, randomized, three-treatment, three-period, crossover, single dose study, to investigate drug-drug interaction and relative bioavailability between the fixed dose combination Azelastine hydrochloride / Beclomethasone dipropionate (140/100 μg Azelastine hydrochloride / Beclomethasone dipropionate) Nasal Spray, and Beclomethasone Dipropionate Nasal Spray (100 μg Beclomethasone Dipropionate) in the test vehicle, and the commercially available product, RinoClenil® Nasal Spray (100 μg Beclomethasone Dipropionate), in healthy subjects under fasting conditions.
