Cresemba® in Treating Chinese Patients With IFD Caused by Aspergillus Species or Other Filamentous Fungi

This study is a post-approval commitment study, and is designed to further evaluate the safety and efficacy of isavuconazole in a relatively larger Chinese population who will receive isavuconazole treatment in a post-marketing setting.

This is a single arm, prospective, multi-center study. This study is seeking Chinese patients with proven, probable or possible Invasive Fungal Disease (IFD) caused by Aspergillus species or other filamentous fungi. All the participants will receive isavuconazole treatment. The longest treatment duration in this study is 84 days (up to 180 days for participants diagnosed with IM).

The primary objective is to characterize the safety and tolerability of isavuconazole through observing the treatment emergent adverse events.

    An adverse event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A TEAE was an AE that started on or after the first administration of study intervention until 28 days after last dose of study intervention.
