Image A. This 25 year old woman was previously well and presented with a pneumonia of uncertain aetiology. She has infiltrates in right upper-lobe and left middle and lower zones. The diagnosis was later made of chronic invasive pulmonary aspergillosis by bronchoscopy . Subsequently she was diagnosed with adult-onset chronic granulomatous disease with neutrophil function assays.
Image B. CT scan of the thorax just below the carina, showing almost complete opacification of the right lung and marked nodular shadowing around the hilum of the left lung.
Image C. Progression of pulmonary infiltrates are seen seven weeks later, despite administration of amphotericin B.
Image D. CT scan of the thorax above the carina showing near complete opacification of the right lung and multiple discrete nodular shadows in the left lung.

VL-2397 (formerly known as ASP2397) is a novel antifungal drug initially developed by our partner, Astellas Pharma. This drug was isolated from a leaf litter fungus Acremonium species collected in a Malaysian national park. Astellas presented two posters at the 2014 ICAAC meeting which described the in vitro and the in vivo antifungal activities of this drug. The differentiating attributes from the preclinical data of VL-2397 include:
- A novel mechanism of action, with a potential to be complementary or synergistic with the existing classes of antifungals.
- Rapid fungal cell kill activity demonstrated in preclinical models, which was faster than marketed antifungals.
- Activity against azole-resistant fungal species.
- Low propensity for P450 drug-drug interactions.
