Filter by:Concentrations of voriconazole in pulmonary epithelial lining fluid and in serum are compared after inhalation of 40 mg voriconazole b.i.d. for two days or oral intake of voriconazole tablets 400 mg bid for 1 day followed by 200 mg b.i.d. for one day, respectively.
Double blind, placebo controlled, ascending single oral dose, sequential group study. Forty subjects will complete the study in 5 cohorts (Groups A to E), each group consisting of 8 subjects. Each subject will be on study for approximately 6 weeks. Each subject will participate in one treatment cohort only, residing at the Clinical Research Unit (CRU) from Day -1 (the day before dosing) to Day 6 (120 hours post-dose). Each cohort will be dosed in a leading edge design in which two subjects will receive study drug (1 active and 1 placebo) on the first dosing day, and the last 6 will receive study drug (5 active and 1 placebo) on the second dosing day. All subjects will return for a post-study visit 8 to 10 days after the dose of study medication. Cohorts will be dosed at 2 weekly intervals. There will be a review of safety data, after the first two subjects have been dosed and before dosing of the subsequent six subjects. There will be a complete review of safety and pharmacokinetic data of each cohort prior to each dose escalation.
Double blind, placebo controlled, parallel group ascending dose study evaluating single and multiple (x8 days) dose levels of F901318 in groups of male healthy subjects with the objective of defining a dosing schedule for phase ll clinical trials. F901318, a novel and potent antifungal agent for the treatment of invasive aspergillosis, will be delivered intravenously in a range of dosing schedules driven by pharmacokinetic evaluation in real time. Safety and tolerability of those schedules will also be assessed.
Compare the incidence of severe clinical exacerbations in the treatment of ABPA, between a strategy with a maintenance treatment and a conventional strategy without antifungal maintenance therapy.
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.
The primary objective of this study is to assess and compare the safety of posaconazole with voriconazole in Japanese participants with aspergillosis.
F901318 is a potent new antifungal agent for the treatment of systemic fungal infections. This study will test it for the first time in man with the objective of assessing its safety, tolerability and pharmacokinetic profile.
Although the clinical outcome in patients with Invasive Aspergillosis (IA) is largely dependent on early initiation of effective treatment with antifungal drugs, diagnosing IA is still a critical problem. Symptoms are non-specific and available diagnostic tools are either invasive or have low sensitivity and specificity. This often results in a diagnostic delay, with patients developing more extensive disease. Furthermore, as long as IA is present, oncological follow-up treatment is not feasible. Inaccuracy in diagnosing IA can cause serious treatment delay and increased mortality. However, an empirical strategy with prophylactic anti-mould therapy is not feasible considering both possible side effects and costs. In order to safely continue the use of a pre-empirical strategy, improved (non-invasive) diagnostic tools are desirable. In a pilot study de Heer et al. showed that it is possible to discriminate between patients with IA and their neutropenic controls by exhaled breath analysis using an electronic nose (eNose). In this study the investigators aim to test whether an eNose could be useful as a diagnostic tool in a prospective setting. The gold standard in exhaled breath analysis is Gas Chromatography - Mass Spectrometry (GC-MS). This technique enables identification of volatile organic compounds (VOCs) in breath of patients. It is possible that there are Aspergillus specific VOCs in the breath of patients with IA. The composition of the lung microbiome seems to be an important factor in both health and disease. It is likely that the microbiome of the lung changes in prolonged neutropenia, therefore possibly creating a niche for molds and yeasts. Comparing the microbiome of patients with prolonged neutropenia who develop IA with those who do not, can learn us more about the pathogenesis of this disease. This knowledge could be used to investigate new treatment options for Invasive Aspergillosis. Hypothesis The investigators hypothesize that airway microbial (viral, bacterial) presence and exhaled molecular profiles as obtained from patients with prolonged neutropenia due to treatment of hematological malignancies, are different between patients who develop IA and patients who do not.
