Inclusion Criteria: * mycological diagnosis of candidemia and/or invasive candidiasis from a sample taken less than or equal to 96 hours before randomization (defined as: at least 1 blood culture positive for Candida or positive test for Candida from a sponsor approved rapid diagnostic test or positive gram stain for yeast or positive culture for Candida spp. from a specimen obtained from a normally sterile site) * willing to initiate or continue medical treatment to cure infections, including receipt of antibiotics and surgical procedures, if required.

If the subject is unable to consent for himself/herself, a legally acceptable representative must provide informed consent on their behalf. * presence of one or more systemic signs attributable to candidemia and/or invasive candidiasis Exclusion Criteria: * Any of the following forms of IC: 1. Septic arthritis in a prosthetic joint (septic arthritis in a native joint is allowed) 2. Osteomyelitis 3. Endocarditis or myocarditis 4. Meningitis, endophthalmitis, or any central nervous system infection * neutropenia * alanine aminotransferase or aspartate aminotransferase levels \>10 fold the upper limit of normal * severe hepatic impairment in subjects with a history of chronic cirrhosis * greater than 48 hours systemic antifungal treatment at approved doses to treat candidemia * pregnant females * lactating females who are nursing * known hypersensitivity to CD101, caspofungin, any echinocandin, or to any of their excipients * previous participation in this or any previous CD101 study * recent use of an investigational medicinal product within 28 days of first dose of study drug or presence of an investigational device at the time of screening * Principal Investigator considers the subject should not participate * presence of indwelling vascular catheter or device that cannot be removed and is likely to be the source of candidemia
