Observation study of patients with chronic rhinitis or chronic urticaria in Thailand
This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will assess the efficacy and safety of additional quilizumab therapy in adult patients with Chronic Spontaneous Urticaria resistant to antihistamine treatment.
Chronic urticaria is defined by urticarial lesions persisting at 6 weeks. The cause is not found in about 75% of cases (chronic idiopathic urticaria). The gold standard treatment consists of anti-H1 molecules. In severe cases, refractory to anti-H1, few therapeutic alternatives exist. Methotrexate, which is not expensive and often prescribed by dermatologists, has been efficiently tried in an open study on severe chronic idiopathic urticaria, and also in few case reports.
The antihistamines with inhaled steroids are the cornerstone on the symptomatic therapy in the management of patients with rhinitis and the first line of treatment in patients with urticaria. Currently, the use of antihistamines has become popular due to its excellent safety profile and clinical efficacy, however to the investigators knowledge, there are no studies about the pharmacokinetic and pharmacodynamic effects of these drugs in patients of tropical Latin America. The investigators main interest is to evaluate if skin test inhibition correlates with the clinical effect of five anti-histamines.
This is a study to evaluate the efficacy and safety of desloratadine (MK-4117) in Japanese participants with chronic urticaria. The primary hypothesis is that the efficacy of desloratadine 10 mg and 5 mg is superior to placebo as based on the change from Baseline in the sum score of pruritus/itch and rash as assessed by the Investigator at Week 2.
To compare the relative bioavailability and pharmacokinetic characteristics of a newly developed bepotastine formulation, bepotastine salicylate, with a conventional formulation, bepotastine besilate, in healthy subjects with a single dose, randomized, open-label, 2-sequence -2period crossover study.
The aim of this study is to investigate the pathophysiological mechanism of omalizumab in patients with documented chronic urticaria who have complaints under standard antihistamine treatment. With this study the investigators will assess the correlation between Fc-IgE receptor downregulation as well as functionality and clinical response to omalizumab treatment in patients with chronic urticaria. This may be an approach for other diseases as well, where Fc-IgE receptor crosslinking are essential. The treatment time is set for a total of 4 monthly applications of omalizumab. According to the dosage recommendations of recent studies, fixed doses of 300 mg omalizumab are administered subcutaneously.
This study will assess the impact of omalizumab on the quality of life improvement when added to the standard therapy in refractory patients suffering from chronic spontaneous urticaria and angioedema.
Urticaria is a common dermatology disease. Urticaria affects nearly 25% of the population at some time in their lives. Recurrent skin itch, insomnia, daily activities limitation greatly affect the quality of life. Some patient with chronic urticaria who had poor response to antihistamine may need second line medication. In United States, up to 54% chronic urticarial patient use oral corticosteroid to control. However, long-term use of oral steroids still needs to consider the impact of its side effects. Therefore, patients may seek for alternative medicine as an adjuvant therapy. It is still lack large-scale clinical trials in Traditional Chinese Medicine research of chronic urticarial. The aim of this study is to conduct a double-blind, randomized clinical trial to analyze the effectiveness of Chinese medicine in chronic urticaria and its possible mechanisms.
