Deposition of Inhaled Liposomal Amphotericin B in Chronic Pulmonary Aspergillosis (CPA)

Starting soon · Phase 1

Conditions studied: Chronic Pulmonary Aspergillosis

In brief

This study evaluates and aims to optimize inhalation treatment with nebulized liposomal amphotericin B in patients with chronic pulmonary aspergillosis. The primary objective is to assess the pulmonary deposition and intrapulmonary distribution of liposomal amphotericin B after nebulization, using technetium-99m-labeled liposomal amphotericin B and SPECT/CT imaging. The study also aims to generate data to inform optimization of inhalation treatment design. Participants will receive two different doses of nebulized liposomal amphotericin B (12 mg and 24 mg) on separate study days. After each administration, participants will undergo SPECT/CT imaging to assess pulmonary deposition. Blood samples will be collected on both study days and after study treatment to evaluate safety and measure systemic amphotericin B concentrations. Participants will also perform spirometry using a handheld device and complete a treatment satisfaction questionnaire on both study days.
