Isavuconazole for the Prevention of COVID-19-associated Pulmonary Aspergillosis

Adult patients with polymerase chain reaction (PCR)-confirmed SARS-CoV-2 (COVID-19) infection without a diagnosis of invasive aspergillosis who are hospitalized in the ICU are eligible for inclusion in this study and will be randomized to the isavuconazole plus standard of care (SOC) group or placebo plus SOC group. If randomized to the isavuconazole group, participants will receive intravenous isavuconazonium sulfate 372 mg every 8 hours for 6 doses followed by intravenous isavuconazonium sulfate 372 mg once daily for up to 28 days. If randomized to the placebo group, participants will receive intravenous placebo every 8 hours for 6 doses followed by once daily for up to 28 days. Both groups will receive the usual SOC. Following randomized to the two treatment arms, participants will be screened for invasive aspergillosis with thrice weekly fungal cultures from tracheal aspirate (TA) secretions or thrice weekly serum galactomannan (GM) testing (if TA unable to be performed, contraindicated, or participant is not intubated). If invasive aspergillosis or other invasive fungal infection is detected, antifungal therapy will be initiated (if the participant is in the placebo arm) or modified if needed (if the participant is in the isavuconazole arm).
