Active clinical trials for "Chronic Urticaria"

The purpose of the study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of a single dose of UB-221 as an add-on therapy in patients with Chronic Spontaneous Urticaria.

Study to determine the efficacy of benralizumab when compared to placebo in patients with chronic hives that do not respond to antihistamine treatment

This was a Phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of omalizumab administered subcutaneously as an add-on therapy for the treatment of adolescent and adult participants 12 - 75 years who received the diagnosis of refractory chronic spontaneous uriticaria and who remained symptomatic despite standard-dosed non-sedating H1 antihistamine treatment.

The investigators are recruiting for a chronic hives study. This research is being done to test whether an investigational drug called AstraZeneca drug (AZD)1981 may be helpful for treating people with Chronic Idiopathic Urticaria who continue to have symptoms despite taking antihistamines. The word "investigational" means that AZD1981 is not approved for marketing by the Food and Drug Administration (FDA). The FDA is allowing the use of AZD1981 in this study. People with chronic hives lasting for at least 6 months and without a known cause may join. The study involves 6 visits over 8 weeks. Approximately 48 participants expected to take part in this study at the Johns Hopkins Asthma and Allergy Clinic. All participants will be treated with the study medication and/or placebo for 8 weeks. The results of this trial may have a benefit others with Chronic Idiopathic Urticaria who don't respond well to antihistamines by generating experience and data to support the design of a larger, multicenter trial investigating the efficacy of AZD1981 in treating antihistamine refractory CIU.

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.

This multicenter, randomized, double-blind, placebo-controlled study will evaluate the efficacy and safety of subcutaneous (SC) omalizumab (Xolair) as an add-on therapy through 48 weeks for treatment of H1 antihistamine refractory chronic idiopathic urticaria (CIU). After completing an initial 24-week open-label treatment period with omalizumab 300 milligrams (mg) every 4 weeks (Q4W), participants responding to omalizumab will be randomized at a 3:2 ratio (omalizumab:placebo) to either continue omalizumab or be transitioned to placebo for a further 24 weeks.

This study is being done to find out if a drug called Abatacept (Orencia ®) is safe and effective in treating people with chronic urticaria (persistent hives).

The study is a Phase II, dose-ranging, multicenter, randomized, double-blind, placebo-controlled, parallel-group study of the efficacy and safety of a single subcutaneously administered omalizumab dose as add-on therapy for the treatment of adolescent and adult patients 12-75 years old who have been diagnosed with CIU and remain symptomatic despite treatment with therapeutic doses of an H1 antihistamine. The study will enroll approximately 76 patients at approximately 45 study centers in the United States and Germany.

This double-blind pilot study was conducted to establish the best way of using desloratadine treatment to protect quality of life of chronic idiopathic urticaria (CIU) patients, after an initial 4-weeks of daily treatment: prolonging systematic daily treatment or as needed (PRN; in the case of symptoms).

The purpose of this study is to compare urticaria lesions (size, kinetics) by thermography, volumetry and digital time lapse photography in CU patients treated with desloratadine 5 mg or desloratadine 20 mg. Hypothesis: Updosing of desloratadine (20mg) is more efficient in the treatment of urticarial lesions as compared to standard dosing (5 mg desloratadine).
