Filter by:This is an open-label, randomized study to investigate the relative bioavailability of two formulations of BCX7353 and to determine if there is a food effect
This is an open-label, three part study to evaluate the effect of BCX7353 on drug transporters as well as the effect of an inhibitor of drug transport on BCX7353.
International, multicenter, observational, longitudinal monitoring study to identify, validate and/or monitor Mass Spectrometry (MS)-based biomarker/s for Hereditary Angioedeme (HAE) disease and to test the clinical robustness, specificity, and predictive value of theese biomarker/s
The overall hospitalizations for a diagnosis of angioedema doubled from the year 2000 to 2009. Although some of the cases represented hereditary angioedema or ace-inhibitor induced angioedema, the majority of episodes were idiopathic. Idiopathic Angioedema (IAE) can be life- threatening especially when affecting tissues within the respiratory tract. No clear guidelines exist for management of this important condition for clinicians. Current therapies typically include avoidance of potential triggers and use of medications either for prophylaxis or for acute events, such as antihistamines, corticosteroids, and epinephrine. There remains a critical need for therapeutic options to provide more effective prophylaxis.
Previous studies reported infraclinical modifications of the homeostasis in chronic urticaria, recurrent idiopathic angioedema and hereditary angioedema. This study aim to compare groups with isolated wheals, isolated angioedema, combination of both and hereditary angioedema in terms of coagulation pathways.
This 3-part study will evaluate the safety and efficacy of an oral treatment, BCX7353, in preventing angioedema attacks in subjects with hereditary angioedema (HAE). In Part 1 of the study, eligible subjects will be randomized to receive oral BCX7353 or placebo for 4 weeks. Assuming successful completion of Part 1, additional subjects will be randomized in Part 2 to one of 2 lower doses of BCX7353 or placebo. Part 3 will enroll additional subjects into one of three doses of BCX7353 or placebo. The study will compare the number of acute attacks in each treatment group, as well as a number of other clinical and pharmacologic outcomes, and the safety and tolerability of each dose of BCX7353 compared to placebo.
The purpose of this study is to determine if an investigational treatment is safe and well tolerated when administered by intravenous (IV) infusion in Japanese subjects with HAE.
In emergency room, this is crucial to diagnose an acute attack of hereditary angioedema (HAE) to quickly provide the efficient treatment. Currently, there is no specific biomarker for acute attack of bradykinin-mediated angioedema to help clinicians for patient care. However, previous works are carried out for that purpose. All the potential candidate biomarkers must be validated in prospective studies to estimate their specificity and sensitivity values, and to understand their potential utility in patient care. The main goal of this clinical trial is to estimate the diagnostic value of VE-cadherin in pediatric population, for the differential diagnosis between HAE crisis and angioedema resulting of mast cell activation crisis (the main differential diagnosis of HAE).
Diagnosis of angioedema (AE) is difficult especially in emergency room. Two forms should be evoked: histaminic AE (allergic or not, which represent 95% of cases) and bradykinic AE (hereditary or acquired deficiency, with or without C1 Inhibitor) rarer but with more severe prognosis. The distinction is based on clinical features (spontaneous crisis duration, presence of concomitant hives, atopic history...). Sometimes it could be difficult to make the difference. Nowadays, there is no biological marker of the crisis. The search for biomarkers could improve the diagnostic and therapeutic management of AE. Previous work has identified targets: D-dimer, C4, and VE-cadherin. We wanted to know the sensitivity and specificity of these markers. We conducted a prospective study evaluating the D-dimer assays, complement and VE-cadherin during an episode of AE. Three groups of patients were tested: bradykinic AE (peripheral or abdominal attacks), histaminic AE, and abdominal pain (non-bradykinic and non-histaminic etiology) at the time (day 0) and at distance from the crisis (D7).
Specific treatments for angiotensin-converting-enzyme inhibitor (ACE-I) and angiotensin-receptor-blocker (ARB)-induced angioedema exist. Early access to these treatments is challenging because they are expensive and have short shelf lives making it illusory that all emergency department (ED) stock them. The aim of this retrospective study was to define, for each patient with a confirmed ACE-I or ARB-induced angioedema, at which step of the care, the specific treatment was administered. The second objective was to analyse the availability of these treatment in the area around Lyon, France and the factors that may influence it.
