NCT ID: NCT06447402 Recruiting - Clinical trials for Chronic Pulmonary Aspergillosis

A Trial to Compare Nebulized Amphotericin B and Nebulized Normal Saline as Maintenance in Patients With Chronic Pulmonary Aspergillosis

NAB-CPA
Start date: June 3, 2024
Phase: Phase 3
Study type: Interventional

The treatment of CPA is with oral itraconazole for 6-12 months. Oral itraconazole results in better clinical outcomes in CPA compared to supportive care. A recent study comparing 6 months with 12 months of oral itraconazole for longer duration treatment found longer duration reduced CPA relapse and improved clinical outcomes. However, longer duration of itraconazole could cause emergence of drug resistant Aspergillus fumigatus and therapy related adverse event. A recent study found nebulized amphotericin B non-inferior to oral itraconazole for treating CPA as primary therapy. However, the study was small and included patients with simple aspergilloma and used nebulized amphotericin B for 7 days.To be effective, an inhaled drug should be delivered in sufficient quantity to achieve therapeutic levels.The minimum inhibitory concentration of amphotericin B for A.fumigatus is 0.5 mg/L. In one study, nebulization of 30 mg of amphotericin B deoxycholate achieved a mean concentration of 0.68 mg/L in the bronchoalveolar lavage fluid. Notably, the serum levels of amphotericin B after nebulization are 20 times less than after systemic administration and is safer. Further, there is a dose-response relation with nebulized amphotericin B, the higher the dose used for nebulization, the higher are the levels achieved in the lung tissue. Nebulized amphotericin B has been used in lung transplant recipients to prevent invasive aspergillosis. Also, two recent studies have demonstrated that use of nebulized amphotericin B as maintenance therapy led to a reduction in ABPA relapse rates and prolonged time to exacerbation. We believe that inhaled amphotericin B as a maintenance therapy could reduce CPA relapse and prolong time to relapse. In this study, we plan to evaluate nebulized amphotericin B as a maintenance therapy in clinically stable CPA patients treated with 12 months of oral antifungal therapy

Efficacy of Intrabronchial Voriconazole Instillation for Inoperable Pulmonary Aspergilloma

Start date: December 1, 2016
Phase: Phase 2/Phase 3
Study type: Interventional

Pulmonary aspergillomas are a common cause of recurrent hemoptysis which may be moderate to severe in 2 to 50 % of cases and may be life threatening. Surgical resection, though curative, may not be feasible in significant number of patients and also associated significant post op complications. Bronchial artery embolisation (BAE) is effective for acute control of hemoptysis, however recurrences may occur in upto a quarter of subjects over a 1 year period. Aspergilloma is caused by a fungus hence systemic antifungals seem appropriate choice. However the fungus only partially touch the walls of the cavities containing them and rarely come into contact with the bloodstream. This is the major reason why the systemic administration of antifungal agents is ineffective in eradicating the condition. If surgical resection is not a treatment option to control recurrent hemoptysis, instillation of antifungal agents in an aspergilloma cavity could be considered(QoE II).The instillation of antifungal directly into the cavity (intra-cavitatory) containing aspergilloma brings the drug in contact with the fungus. Thus may lead to antifungal action and shrinkage or complete disappearance of aspergilloma. This can be achieved either by percutaneous route or bronchoscopically. Percutaneous approaches have been investigated however they can sometimes cause fungal spread in thoracic space resulting in fungal empyema which should be carefully avoided. Endobronchial instillation of antifungals have been investigated and found to be safe and effective in controlling hemoptysis, however published data comprise of case reports or small case series. Recently we have published our experience of intrabronchial voriconazole in aspergilloma among 82 patients and found to be safe and effective in hemoptysis control, with transient post procedure cough as an adverse effect with no major serious adverse events. Multiple small studies and case reports have published the safety and efficacy of voriconazole. However, a quality data in the form of randomized controlled trial (RCT) is not there. Therefore, we planned this RCT to assess the efficacy of intrabronchial voriconazole in inoperable aspergilloma.
