Active clinical trials for "Pulmonary Aspergillosis"

The primary safety objectives were: Part 1: To determine the safety and tolerability of single doses of ZP-059 in healthy subjects Part 2: To determine the safety and tolerability of multiple doses of ZP-059 in subjects with mild stable asthma Part 3: To determine the safety and tolerability of single doses of ZP-059 in subjects with mild to moderate stable asthma. The primary PK objectives were: Part 1: To characterize systemic PK of voriconazole and N-oxide voriconazole after single doses of ZP-059 in healthy subjects Part 2: To characterize systemic PK of voriconazole and N-oxide voriconazole after multiple doses of ZP-059 in subjects with mild stable asthma Part 3: To characterize systemic PK of voriconazole and N-oxide voriconazole after single doses of ZP-059 and single doses of oral voriconazole in subjects with mild to moderate stable asthma.

The investigators propose to study the efficacy and safety of three-week antifungal therapy with caspofungin in hospitalized patients with proven or probable IPA underlying chronic obstructive pulmonary disease.

This study assesses the pharmacokinetics and safety of the new antifungal F901318 in AML patients.

voriconazole is recommended as first-line therapy for invasive pulmonary aspergillosis, however the efficacy and safety of voriconazole for treating invasive pulmonary aspergillosis secondary to COPD is not clear. This study aims to investigate the effectiveness and tolerability of intravenous voriconazole for treatment of invasive pulmonary aspergillosis in Chinese patients with COPD, by monitoring changes in clinical symptoms, eradication of aspergillus, improvement of chest imaging as well as record of possible adverse reactions following 2-week intravenous instillation of voriconazole.

Multiple factors are associated with a large variability in voriconazole exposure following standard dose administration, such as non-linear saturable pharmacokinetics, drug-drug interactions, liver disease, patient age, and genetic polymorphism of the metabolic enzymes. Voriconazole is extensively metabolized by the human hepatic enzymes, primarily mediated by CYP2C19. The polymorphisms account for a relatively large portion of inter-individual variance observed in voriconazole plasma concentrations. However, there are limited data on the relationships between voriconazole blood levels and clinical outcomes or safety in Asian populations. The purpose of this study is to investigate the relationships of voriconazole blood levels with genetic polymorphism, safety, and clinical outcomes in immunocompromised patients with invasive pulmonary aspergillosis.

The main objective of this study is to determine if a doubling of serum TARC (compared to baseline) is associated with the occurrence of exacerbations of ABPA. The secondary objectives of the study are : To investigate if induced sputum eosinophils count (compared to baseline) is associated with the occurrence of exacerbations. To examine if the exhaled NO (compared to a baseline) is associated with the occurrence of exacerbations. To investigate if activation of circulating T cells (compared to a baseline) is associated with the occurrence of exacerbations. To examine if the rate of specific Asp f IgG measured by ELISA (compared to a baseline) is associated with the occurrence of exacerbations. To determine if the variation of one of the markers above, TARC or Asp f specific IgE measured at baseline, may be associated with the radiological stage of the disease (ABPA-S, ABPA-CB, ABPA-ORF). To investigate if there is a link between fungal exposure at home (visually assessed by the contamination level and the proportion of positive samples for Asp. f) and the frequency of exacerbations. To establish if some of the clinical, functional or biological data studied are associated with the frequency of exacerbations.

Study the incidence and outcome of invasive pulmonary aspergillosis (IPA) in ICU patients with severe influenza and in influenza-negative control patients with severe community-acquired pneumonia

Background Invasive pulmonary aspergillosis (IPA) remains an important cause of morbidity and mortality among patients with hemato-oncological malignancies. Due to the crude mortality of >90% in absence of adequate treatment, timely diagnosis and early start of antifungal therapy are key factors in the successful treatment of IPA. Various studies have shown that early initiation of antifungal therapy may improve IPA survival to above 70%. Diagnosis of IPA, however, remains difficult as clinical signs and symptoms as well as radiological findings are often unspecific and conventional culture methods lack sensitivity. In recent years antigen testing has therefore become one of the cornerstones of IPA diagnostics. Brochoalveolar lavage (BAL) Galactomannan (GM) testing is currently the most promising approach for early detection of pulmonary infections by this fungus. However, limitations of GM detection are assay turn-around time, which varies widely between centers (less than a day to several days), and the need for appropriately equipped laboratories that routinely test for this antigen. These limitations are overcome by the Aspergillus Lateral-Flow Device (LFD), a novel point-of-care (POC) test for IPA diagnosis developed by Dr Thornton at the University of Exeter, UK. This simple, rapid (15 min), single-use test can be performed in rudimentary facilities using BAL specimens. In a retrospective single centre study we have recently evaluated the LFD test in 39 BAL samples from hematologic malignancy patients and solid organ transplant recipients. Sensitivities and specificities of BAL LFD tests for probable IPA were 100% and 81%, respectively. Galactomannan levels in cases with negative LFD were significantly lower than in patients with positive LFD (P <0.0001). We concluded that the LFD test of BAL specimens is performed easily and provides accurate and rapidly available results. Therefore, this new point-of-care test may be a very promising diagnostic approach for detecting IPA in BAL specimens from haematological malignancy and SOT patients. For routine clinical use, however, multicenter studies with larger sample sizes also from other patient collectives are necessary. In this multicenter study we will evaluate the LFD test in BAL samples. Study Objectives Primary Objectives To evaluate the Lateral Flow Device test, a rapid (15 min), point-of-care test for IPA diagnosis using bronchoalveolar lavage (BAL) fluids from patients at risk for IPA. Secondary Objective To evaluate the potential of BAL Lateral Flow Device test for prognosis in patients with IPA. Study Design This is a prospective multi-center study conducted in three centers in Austria (Graz, Vienna and Innsbruck) and one centre in Germany (Mannheim). In order to meet the objectives an estimated number of 300 BAL samples from patients at risk for IPA (50 to 100 per centre) will be included in the study cohort. The Lateral Flow Device test will be performed prospectively in BAL samples from the patients and results will be compared to GM results, PCR findings, clinical/radiological findings as well as conventional culture results. In addition, retrospective testing of BAL samples that were previously routinely tested for GM will be performed in up to three participating centers (Graz, Innsbruck and Mannheim) to ensure to reach the proposed number of 300 BAL samples. The treating clinicians will not be informed about BAL Lateral Flow Device test results and the test will therefore have no impact on patient management / treatment decisions.

Prospective multi-center surveillance study on the prevalence of azole-resistant Aspergillus spp. in clinical isolates of patients with pulmonary colonization or invasive infections in Switzerland

Asthma is severe when it cannot be controlled with maximum-dose inhaled therapies while management of comorbidities and other precipitating or aggravating factors has been optimized. Allergic bronchopulmonary aspergillosis (ABPA) is a complex bronchopulmonary disease resulting from immunological reactions against Aspergillus Fumigatus. The development of a model of bronchial epithelium generated from patients with chronic lung disease will allow the modeling of bronchial tissue to understand the formation of these mucus plugs. This study aims to validate this model The investigators propose to verify the feasibility of obtaining and comparing two epithelia in two populations based on the following experiments: Differentiation of an Induced Pluripotent Stem cell (iPSC) clone derived from blood sample (Peripheral Blood Mononuclear Cells) of Type 2 inflammation (T2) severe asthma and Allergic Bronchopulmonary Aspergillosis (ABPA) in order to obtain differentiated bronchial epithelia in vitro.
