Study to Evaluate the Safety, Tolerability and Efficacy of Cannabidiol (CBD) as a Steroid-sparing...
Chronic Spontaneous UrticariaEach patient will commence the study with a one month run-in period in which he/she will be administered individual patient Standard of Care :anti-histamines and steroids as needed plus placebo (olive oil). After the run-in period, doses of CBD will be incresed during the first six weeks of the study. At the conclusion of the six weeks CBD dose escalation segment of the study, if the 300 mg CBD dose level is deemed safe for two weeks with standard of care doses of anti-histamines, patients will continue receiving 300 mg CBD with Anti-histamines as needed for an additional follow-up period of three month. Each patient will serve as his/her own control.
The Efficacy of a Pseudoallergen-Free Diet in the Treatment of Chronic Idiopathic Urticaria and/or...
UrticariaAngioedemaThis study involves investigating the effects of a pseudoallergen-free (active) diet compared with a control (placebo) diet in the treatment of Chronic Idiopathic Urticaria (CIU) and/or Angioedema. The hypothesis is that over a four-week intervention period, the pseudoallergen-free diet will be more effective than the placebo diet in reducing the frequency and severity of CIU and/or Angioedema.
The Efficacy and Safety of Desloratadine With Levocetirizine in Treatment of Chronic Idiopathic...
Chronic Idiopathic UrticariaUrticariaObjective: To compare the efficacy of desloratadine 5mg (Denosin®) and levocetirizine 5mg (Xyzal®) once daily in the treatment of patients with CIU over 6 weeks. Trial design: Randomized, Double-Blind, Active-Controlled, Parallel-Group Study. Primary end point: To evaluate the change in average AM/PM reflective pruritus score from baseline recorded in the subjects' diaries during the first two weeks of the treatment. Secondary Objectives: To assess the efficacy and safety of desloratadine 5mg (Denosin®) and levocetirizine 5mg (Xyzal®) once daily in the treatment of subjects with CIU over 6 weeks.
Efficacy of Low-dose Interleukin-2 Treatment in Chronic Spontaneous Urticaria
Chronic Spontaneous UrticariaThis study is a randomized, controlled, single-center clinical study to evaluate the short-term efficacy of low-dose Interleukin-2 injection as an add-on therapy for the treatment of patients aged 18-75 who have been diagnosed with CSU and remain symptomatic despite oral antihistamine treatment .
Study to Evaluate the Therapeutic Equivalence of SYN008 Versus Xolair® in the Treatment of Patients...
Chronic Spontaneous Urticaria• This study is a multicenter, randomized, double-blind, parallel-group, positive-controlled phase III study to evaluate the therapeutic equivalence of SYN008 versus omalizumab for injection (Xolair®) in the treatment of CSU patients who remain symptomatic despite antihistamine treatment.
High Dose Vitamin D Supplementation in Chronic Spontaneous Urticaria
UrticariaChronic spontaneous urticaria is an inflammatory disease which is characterized with intermittent or daily urticaria. This diseases lasts for more than 6 weeks. Several recent studies have suggested a role for vitamin D in modulation of immune system and pathogenesis of chronic urticaria.

Chronic Idiopathic UrticariaEvaluation whether canakinumab leads to improvement of urticaria
Efficacy of Antihistamine Dosing-up and add-on Treatment With H2-receptor Antagonist
Chronic UrticariaA randomized open labeled trial to compare the efficacy of antihistamine dosing-up and add-on treatment with H2-receptor antagonist in patients with chronic urticaria
Mast Cell Activation Test in Allergic Disease
AsthmaMastocytosis5 moreActivation of mast cells in the immune system is known to cause allergic reactions sometimes with severe systemic symptoms. The investigators have recently developed a blood-based mast cell activation diagnostic test in which levels of functional activation in-vitro in primary cultured mast cells generated from the peripheral blood of single individuals can be assessed. It is the hypothesis that the test can be used to predict the potential state of in-vivo mast cell activation in any individual based on the functional activation profiles exhibited by their cultured mast cells. The investigators now wish to translate their in-vitro findings in a pilot study to disease groups where mast cell activation is expected to be high. These include highly allergic individuals; those with chronic idiopathic urticaria; those with mastocytosis; and those with the mast cell activation syndrome. Furthermore, they will use the functional genomics approach to identify gene expression biomarkers that are correlated with such diseases. The results will be compared with data that have been collected from a cohort of healthy control blood donors.
Vitamin D Levels in Subjects With Chronic Urticaria and Angioedema
UrticariaAngioedemaThe objective of this study is to perform an exploratory analysis to determine if a possible relationship between vitamin D and chronic urticaria and/or angioedema exists. The study hypothesis is that vitamin D deficiency is associated with chronic urticaria and/or angioedema.
