Pulmatrix Announces Publication on Physiologically Based Pharmacokinetic Modelling of Potential Drug-Drug Interactions with PUR1900, Orally Inhaled Itraconazole
- PUR1900 may be safely administered even in patients taking drugs contraindicated with oral itraconazole.
- Potential to provide an inhalation alternative to oral antifungal therapy in treating ABPA.
- None.
Results demonstrate a low likelihood of clinically meaningful drug-drug interactions when PUR1900 is administered with medications contraindicated with oral itraconazole
Pulmatrix is currently enrolling patients in a Phase 2 study of PUR1900 in adults with ABPA and Asthma
Administration of PUR1900 results in high lung and low systemic itraconazole exposure. Oral itraconazole is a potent inhibitor of cytochrome P450 3A4 (CYP3A4), which alters the metabolism and consequently the plasma concentrations of other drugs metabolized by this pathway. Co-administration of some of these drugs with oral itraconazole is contraindicated due to the potential for drug-drug interactions (DDI).
Pulmatrix today announced publication of "Evaluation of the Potential for Drug‑Drug Interactions with Inhaled Itraconazole Using Physiologically Based Pharmacokinetic Modelling, Based on Phase 1 Clinical Data" in the peer-reviewed American Association of Pharmaceutical Scientists (AAPS) Journal.
Dr. Margaret Wasilewski, Chief Medical Officer of Pulmatrix, commented, "We are pleased to publish the drug-drug interaction modeling study on PUR1900 in the AAPS Journal. This study demonstrates the risk of DDI with PUR1900 (inhaled itraconazole) is lower than with oral itraconazole and PUR1900 may be safely administered even in patients taking drugs contraindicated with oral itraconazole."
Ted Raad, Chief Executive Officer of Pulmatrix, commented, "While oral itraconazole is part of the standard of care for patients suffering from ABPA, its use is limited due to the side effects and drug to drug interactions associated with the high itraconazole plasma concentrations of oral itraconazole therapy. PUR1900 has the potential to provide an inhalation alternative to oral antifungal therapy in treating ABPA."
Pulmatrix is conducting a Phase 2 study of PUR1900 in adults with ABPA and asthma with sites in in

About Allergic Bronchopulmonary Aspergillosis (ABPA)
ABPA is an exaggerated response of the immune system to the fungus Aspergillus fumigatus in patients with asthma and cystic fibrosis. Aspergillus, a ubiquitous fungus, colonizes the airways of patients with asthma and cystic fibrosis and triggers an intense inflammatory response that results in worsening symptoms, more frequent exacerbations, and ultimately lung damage. Current treatment for ABPA consists of prolonged courses of oral corticosteroids, and oral antifungal therapy may be added in patients who do not respond adequately to oral corticosteroid therapy alone. Published studies evaluating antifungal agents in patients with ABPA report some improvement including possible reduction in oral corticosteroid use. However, the use of oral antifungal therapy is limited by systemic side effects. ABPA occurs in approximately
