An aspergilloma (or fungal ball) is a mass of fungus found inside the body, for example inside cavities such as the lungs or sinuses, or as abscesses in organs such as the brain or kidney. They are made up of threadlike fungal strands (hyphae) that are densely packed but only around 1/200 of a millimetre in diameter. A mass of hyphae is called a mycelium.
In this image, a slice through an aspergilloma has been imaged using a transmission electron microscope.

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.
