In Vivo Efficacy of Olorofim against Systemic Scedosporiosis and Lomentosporiosis.

ABSTRACT: Clinically relevant members of the Scedosporium/Pseudallescheria species complex and Lomentospora prolificans are generally resistant against currently available systemic antifungal agents in vitro, and infection due to these species is difficult to treat. We studied the in vivo efficacy of a new fungicidal agent, olorofim (formerly F901318), against scedosporiosis and lomentosporiosis in neutropenic animals. Cyclophosphamide-immunosuppressed CD-1 mice infected by Scedosporium apiospermum, Pseudallescheria boydii (Scedosporium boydii), and Lomentospora prolificans were treated by intraperitoneal administration of olorofim (15 mg/kg of body weight every 8 h for 9 days). The efficacy of olorofim treatment was assessed by the survival rate at 10 days postinfection,
