Filter by:This is a Phase IV, single-site study that will examine blood cells or tissue obtained from CIU ( chronic idiopathic Urticaria) patients receiving open-label treatment with omalizumab at the current FDA-approved dose of 300 mg/month for 12 weeks in addition to standard therapy with anti-histamines. Results from the 3 Phase III studies in CIU patients provide evidence that a meaningful change in symptoms is apparent at 1-2 wks. The Minimal Important Difference (MID) is achieved by 70% of patients by 2 wks on multiple background drugs for hives. The goal is to identity the IgE bearing cell type associated with clinical symptom change.
The investigators surveyed the prevalence of animal allergy and sensitization to animal allergen among participants in international symposium of Korean association for laboratory science (laboratory animal researchers) and companion animal exhibition (pet owner and pet-related industry workers).
This is a multicenter, parallel group, randomized, double-blind, active controlled, Phase III clinical study of cetirizine injection, 10 mg/mL, compared to diphenhydramine injection, 50 mg/mL (Benadryl or generic equivalent) with acute urticaria requiring treatment.
The investigators will evaluate sensitization to animal allergens and allergic symptom during contacting animal allergens in Korean veterinary researchers who attend their annual conference. The investigators will compare sensitization to animal allergen and other clinical and occupational factors between subjects who suffer from allergic symptom during contacting animal and those who do not.
The aim of this study is to determine whether autologous adipose tissue derived Mesenchymal Stem Cells of treatment for chronic autoimmune urticaria is safe and effective.
This is a single center, non-comparative exploratory study, to investigate the effect of omalizumab over a 3-month treatment period in adult (≥18 years) patients with chronic idiopathic urticaria who had remained symptomatic despite the use of high dose H1-antihistamines.
Pediatric mastocytosis is an orphan disease, which encompasses several clinically distinct entities including solitary mastocytoma, urticaria pigmentosa, diffuse cutaneous mastocytosis and the newly recognized mast cell activation syndrome. The most common form of pediatric mastocytosis is cutaneous maculopapular mastocytosis (CMPM), also known as urticaria pigmentosa (UP). There are significant knowledge gaps regarding the genetic basis of pediatric mastocytosis and the functional activity of mast cells in this condition. The Pediatric Dermatology and Pediatric Oncology services at the University of Minnesota Masonic Children's Hospital are seeing significant growth in clinical volumes of pediatric mastocytosis, including rare, familial cases. The aims of this study are to prospectively explore germline risk for UP and to perform a mutational analysis to identify somatic mutations, beyond those currently identified, in pediatric patients with UP.
A biological tool for quantitative assessment of Chronic Urticaria (CU) is still in need for monitoring biotherapies. CU is considered as a sudden degranulation of Mast cells / basophils without any identified cause. It is considered that Mast cell/basophil have an abnormally high sensitivity in CU and can be triggered with almost nothing (high irritability). In allergy, basophils degranulation can be reproduced in vitro with allergens. Anti-IgE (immunoglobulin E) antibody mimics allergen triggering of basophils in a dose dependent manner. If basophils are abnormally sensitive in CU, it should be reproduced in vitro at very low stimulation. The main objective of this project is to set up a method to evidence abnormal basophil irritability and look for clinical significance. As many markers characterize basophils in different states, researchers shall also look for a profile possibly associated with CU basophile irritability. Such tests could be useful in CU monitoring.
A safety extension study to evaluate the long-term safety of QGE031 240 mg s.c. given every 4 weeks for 52 weeks in Chronic Spontaneous Urticaria (CSU) patients who completed study CQGE031C2201
This is a non-interventional, multi-country, Latin American study utilizing a prospective single-cohort design. Eligible CU patients will be enrolled in the study and will be followed for 24 months (± 6 weeks). In accordance with the observational nature of the study, there will be no interventions or interference with the routine care of the patient which will be based solely on the clinical judgment of the treating physician. However, with respect to the frequency and schedule of assessments, the schedule included in Table 7-1 will be recommended. The selection of the treatment for CU will be clearly separated from the decision to include the patient in the study, and will be made at the discretion of the treating physician in accordance with standard medical practice, the investigator's clinical judgment, and global urticarial guidelines. In order to prevent selection bias, investigators should offer enrollment to all consecutive patients meeting study criteria, likely to be available for the full duration of the follow-up period of 24 months, and willing to participate in the study. The overall objective of the study is to evaluate in real-life the CU disease burden, the current treatment patterns and the use of health care resources in patients refractory to H1-antihistamine treatment
