Males or females 18 years of age
Established mycological diagnosis of candidemia and/or invasive candidiasis from a sample taken 4 days (96 hours) before randomization defined as
blood culture positive for yeast or Candida OR
Positive test for Candida from a Sponsor-approved rapid IVD OR
Positive gram stain (or other method of direct microscopy) for yeast or positive culture for Candida spp. from a specimen obtained from a normally sterile site
Presence of one or more systemic signs attributable to candidemia or invasive candidiasis appearing from 12 hours prior to the qualifying positive culture through time of randomization
Willing to initiate or continue medical treatment to cure infections, including receipt of antibiotics and surgical procedures, if required
Female subjects of childbearing potential (all female subjects between 18 years <2 years post-menopausal unless surgically sterile) must agree to and comply with using one barrier method (e.g., female condom with spermicide) plus one other highly effective method of birth control, or sexual abstinence while participating in this study. Male subjects must be vasectomized, abstain from sexual intercourse, or agree to use barrier contraception, and also agree not to donate sperm while participating in the study and for 90 days thereafter (and at least 120 days from the last dose of study drug)
For Candidemia only subjects, drawing of a set of blood cultures within 12 hours prior to randomization in the study. The result of these blood cultures is not required for inclusion in the study

Exception: Receipt of antifungal therapy to which any Candida spp. isolated in culture is not susceptible
Alanine aminotransferase or aspartate aminotransferase levels >10-fold the upper limit of normal
Severe hepatic impairment in subjects with a history of chronic cirrhosis (Child-Pugh score >9)
Presence of an indwelling vascular catheter or device that cannot be removed or an abscess that cannot be drained and is likely to be the source of candidemia or invasive candidiasis
Known hypersensitivity to Rezafungin for Injection, caspofungin, any echinocandin, or to any of their excipients
Meets National Cancer Institute Common Terminology Criteria for Adverse Events, version 5, criteria for ataxia, tremor, motor neuropathy, or sensory neuropathy of Grade 2 or higher
History of severe ataxia, tremor, or neuropathy or a diagnosis of multiple sclerosis or a movement disorder (including Parkinson's Disease or Huntington's Disease)
Planned or ongoing therapy at Screening with a known neurotoxic medication
Previous participation in this or any previous rezafungin study
Current participation in another interventional treatment trial with an investigational agent
