Arms Assigned Interventions
Experimental: Group 1

Subjects in the CD101 IV treatment group 1 will receive CD101 IV 400 mg on Day 1 and Day 8, with an optional dose of 400 mg on Day 15 (for all subjects) and an optional dose of 400 mg on Day 22 (only for subjects with IC), if needed.

Daily intravenous placebo infusion when not administered CD101. Daily oral placebo as step down.

Drug: CD101
Intravenous antifungal therapy

Drug: oral placebo
microcrystalline cellulose
Other Name: encapsulated cellulose
Experimental: Group 2

Subjects in the CD101 IV treatment group 2 will receive CD101 IV 400 mg on Day 1 and 200 mg on Day 8, with an optional dose of 200 mg on Day 15 (for all subjects) and an optional dose of 200 mg on Day 22 (only for subjects with IC), if needed.

Daily intravenous placebo infusion when not administered CD101. Daily oral placebo as oral step down.

Active Comparator: Group 3

Subjects in the caspofungin group will receive IV caspofungin (a single 70 mg loading dose on Day 1 followed by 50 mg once daily) for ≥3 days up to a maximum of 21 days for subjects with candidemia only and up to a maximum of 28 days for subjects with IC (with or without candidemia).

After ≥3 days of IV therapy, subjects in the caspofungin group can be switched to oral step-down therapy of fluconazole (a loading dose of 800 mg [4 capsules] on the first day followed by 400 mg [2 capsules]/day thereafter). 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.
