Phase 3 |
Detailed Description

Experimental: Group 1: Rezafungin for Injection Subjects in Rezafungin treatment group will receive a 400 mg loading dose in Week 1, followed by 200 mg once weekly, for a total of 2 to 4 doses. Daily intravenous placebo infusions, when not administered Rezafungin and a daily placebo for oral step-down therapy (first eligibility on Day 4 or later as advised by a site's national/regional/local guidelines) administered every day. |
Drug: Rezafungin for Injection

Active Comparator: Group 2: Caspofungin Subjects in caspofungin arm will receive a total treatment of ≥14 days beginning with a single caspofungin 70 mg IV loading dose on Day 1 followed by 50 mg IV once daily up to 28 days. After ≥3 days of caspofungin treatment(or the minimum duration of IV therapy advised by the site's national/regional/local guidelines, whichever is greater), subjects may be switched to oral fluconazole if specific parameters are met. If the subject qualifies, then oral step-down therapy of fluconazole (6 mg/kg to the nearest 200 mg) is administered. After switch to oral step down before Day 8, subjects in the caspofungin group will receive IV placebo on Day 8 to preserve the study blind. |
