Active clinical trials for "Urticaria"

This study was conducted to evaluate the safety and tolerance of desloratadine after 5 weeks of repetitive dosing in children ages 2 to 12 years old with allergic hypersensitivity or chronic hives. All of the subjects enrolled in this trial were previously identified in an earlier trial to be poor metabolizers of desloratadine.

This open-label study is being conducted to determine the effect of DL treatment for CIU on symptom and disease severity, quality of life, daytime functioning, and quality of sleep.

Does presentation of clinical evidence for decision making at point-of-care improve prescribing patterns in ambulatory pediatrics?

The purpose of this study is to assess the efficacy in reducing disease activity and safety of Dupilumab in adult patients with cholinergic urticarial (CholU) who are symptomatic despite H1-antihistamine treatment (licensed dose).

The purpose of this study is to investigate the use of benralizumab is effective in the treatment of chronic spontaneous urticaria (CSU) who are symptomatic despite the use of antihistamines.

This is a study to determine the safety of CDX-0159 in patients with Cold Contact Urticaria, Symptomatic Dermographism, or Cholinergic Urticaria.

Chronic Spontaneous Urticaria (CSU), defined by the persistence of daily or almost daily urticaria over 6 weeks, affects 0.5% to 1% of the general population. In more than half of the cases, it lasts more than 2 years. It can dramatically alter the quality of life, in particular sleep, and generates numerous consultations and hospitalizations, with an average annual cost per patient close to 2000 euros in Europe. The treatment is based on the validated 2nd generation anti-H1 antihistamines dosage of one tablet per day whose effectiveness is satisfactory, however about half the time. In cases of severe CSU refractory to treatment with anti-H1 licensed dosage, few therapeutic alternatives exist, still off-label: the monketulast, an anti-leukotriene, ciclosporine or methotrexate, as immunosuppressants. Various studies have shown the important benefit of an expensive anti-IgE biological: the omaluzimab. Several open studies have also suggested superior efficacy and good tolerability of anti-H1 in higher dosage (double, triple or quadruple) including levocetirizine. The off-label use of these high dosages of anti-H1 is growing very rapidly in France, tending to replace the use of anti-H1 first generation or substitution to another 2nd generation anti-H1 recommended by the French Society of Dermatology. This study, under the aegis of the Urticaria Group of the French Society of Dermatology, intends to compare the efficacy of levocetirizine 4 tablets/day versus 1 tablet/day in the treatment of CSU resistant to anti-H1 licensed dosage.

Chronic urticaria can be defined as the occurrence of widespread daily or almost daily wheals for at least 6 weeks, which may be accompanied by angioedema. While the wheals are transient, the resolution of angioedema is slower than wheals and could take up to 72 hours. The natural course of chronic urticaria is self-limited, with spontaneous remissions and occasional relapses. The investigators calculated a 0.6% (95% CI(Confidence Interval): 0.4-0.8) prevalence in a population study. It has a great impact on patients' quality of life. In a recent national survey on patients attending Allergy Department, chronic urticaria was the disease with greater impact on mental quality of life out of all allergic diseases. In spite of the high morbidity of this disease and the impact in quality of life, there is no available treatment. Last guidelines recommend initiating treatment with antihistamine and if there is no response to increase the dose off-label up to four-fold; systemic corticosteroids are also recommended in short tapering and if no response, the only treatment with clinical evidence to be employed is cyclosporine. As additional data, the treatment cost of this disease has been calculated in 2047$/year. In past years it has been employed the monoclonal humanized anti-Immunoglobulin IgE (iGE) antibody (Omalizumab) to treat moderate to severe asthma with good results. The rationale for this approach in chronic urticaria is that Omalizumab inhibits the binding of IgE to the high affinity IgE receptor (FceRI) which decreases the FceRI expression on the surface of mast cells and basophils so that immunoglobulin G cross linking of the alpha subunit and basophil degranulation is prevented.The hypothesis the investigators are working on is that monoclonal IgE antibody Omalizumab could be effective in controlling chronic urticaria symptoms in patients non respondent to conventional therapy. The investigators hypothesize that Omalizumab is able to revert the basophil or mast cell activation present in chronic urticaria.

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.

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.
