Active clinical trials for "Aspergillosis, Allergic Bronchopulmonary"

This prescreening study is being conducted to diagnose ABPA in selected patients with asthma and to increase the potential number of eligible participants for the ongoing Study 601-0018 of PUR1900 in subjects with ABPA. See: NCT05667662. Additionally, this prescreening study may provide information that could assist the conduct of future studies conducted by Pulmatrix.

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 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.

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.

Chronic bronchial inflammation is an important clinical feature in cystic fibrosis. Approximately 10% of patients with cystic fibrosis suffer from Allergic Bronchopulmonary Aspergillosis. In addition airway inflammation in patients with cystic fibrosis (CF) plays a major role in progression of CF lung disease. In patients with mild disease (Vital capacity >75%) airway inflammation is often under diagnosed. Severity of allergy against Aspergillus fumigatus will be examined using radioallergosorbent test and skin Prick-test. Subsequently, in patients with established sensitization (RAST ≥ 0.35 IU/mL) a specific bronchial provocation with Aspergillus will be performed. In addition, exhaled nitric oxide,carbon monoxide, exhaled air temperature and inflammatory cells in sputum is measured. 24 hours after bronchial allergen provocation, exhaled NO, CO, air temperature, and bronchial responsiveness is determined and a second sputum obtained. This study is designed to characterize patients with CF and sensitization against Aspergillus fumigatus in an early stage to prevent pulmonary complications of ABPA. In addition sputum cytokine profiles in CF patients with mild and moderate disease may be different in patients without and with involvement of small airway disease (SAD).

In this diagnostic study, the aim is at evaluating the diagnostic accuracy of MRI (Magnetic Resonance Imaging) to detect allergic broncho-pulmonary aspergillosis in patients with cystic fibrosis.

The goal of this study is to identify the immunological factors that influence a patient's response to the presence of the fungus Aspergillus fumigatus (A. fumigatus) in the lungs. In patients with cystic fibrosis (CF), this fungus is not known to cause damage to the lungs, but some patients respond with an allergic reaction that may cause wheeze, cough, or difficulty breathing. Approximately 230 patients will be enrolled with an additional 60 people who do not have CF and who do not have a history of asthma to serve as a comparison group.

Voriconazole Inhalation Powder is available on an expanded access basis to patients with pulmonary aspergillosis for up to 12 weeks. Duration of treatment may be extended on a case-by-case basis depending on drug availability and after discussion with the Sponsor.

A spirometry study is performed in a patient diagnosed with allergic bronchopulmonary aspergillosis. An initial measurement is carried out and the patient is then put on a four-week physiotherapy treatment plan. Four spirometry measurements were taken to assess different variables and an improvement in all the spirometry values was established.

This study aims to assess the value of TARC in diagnosis of allergic Bronchopulmonary Aspergillosis.
