Participants received anidulafungin (100 milligrams [mg]) followed by matched placebo-caspofungin once daily (QD) or participants received matched placebo-caspofungin followed by active anidulafungin (100 mg) QD. Anidulafungin loading dose on Day 1 was 200 mg. Study treatments given either entirely as intravenous (IV) therapy or if protocol-specified criteria met, as sequential IV (at least 10 days) then oral antifungal therapy (14 days). Dosage of antifungal therapy (fluconazole or voriconazole tablets) determined by the Investigator. A maximum of 42 days of IV study treatment and a maximum of 14 days of oral study treatment allowed. Thus, participants may have received up to a maximum of 56 days of study therapy.

Participants received caspofungin (35, 50, or 70 mg depending on participant's weight, baseline liver function, or receipt of an interacting drug) followed by matched placebo-anidulafungin QD or participants received matched placebo-anidulafungin followed by active caspofungin (35, 50, or 70 mg) QD. Caspofungin loading dose on Day 1 was 70 mg.

Thus, participants may have received up to a maximum of 56 days of study therapy.

The 95 percent confidence interval (95% CI) was calculated using the method of exact unconditional confidence limits for the difference. Global response (rates of success) by using a 2-sided 95% CI for the true difference in efficacy (Anidulafungin minus Caspofungin) was calculated. Statistical testing was done at 2.5% alpha.
