Inhaled Antifungal Granted Orphan Drug Status for Cystic Fibrosis

The Food & Drug Administration has granted Orphan Drug designation to PUR1900 (Pulmatrix) for the treatment of pulmonary fungal infections in patients with cystic fibrosis (CF).

Recent studies have shown that oral itraconazole is effective in treating fungal lung infections in patients with CF. However, due to the high oral doses needed to reach the lungs, severe adverse events such as liver toxicity are concerning, requiring appropriate monitoring and management.
