Study Endpoints

Primary Endpoints

All-Cause Mortality (US FDA Only)
Day 30 (-2 days)

The number and percentage of subjects in each treatment group who are alive and deceased (or with missing data) in the mITT population.

Global Response as Assessed by Data Review Committee (EU European Medicines Agency [EMA] Only)
Day 14 (±1 day)

The number and percentage of subjects in each treatment group who have a global response of cure (clinical cure as assessed by the Investigator, radiological cure \[for qualifying invasive candidiasis subjects at baseline\], and mycological eradication, as confirmed by the Data Review Committee \[DRC\]), failure and indeterminate in the mITT population. A global response of cure is indicative of an efficacious outcome and the desired result, whereas a response of failure is indicative of a non-efficacious outcome and the undesired response. Indeterminate responses indicate there was not enough data obtained to determine if the response was cure or failure. Definitions for the global responses of cure, failure, and indeterminate are complex. Detailed definitions for the possible responses to this outcome measure type are provided in Table 7 (Global Response) of the clinical protocol.

Treatment Arms

ArmTypeDescription
Group 1: Rezafungin for InjectionEXPERIMENTALSubjects 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.
Group 2: CaspofunginACTIVE_COMPARATORSubjects 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.

Frequently asked questions about Rezafungin

What is Rezafungin used for?

Rezafungin is an investigational small molecule being developed for the treatment of candidemia, a serious fungal infection of the bloodstream. It is currently in Phase 3 clinical development and has not been approved by regulatory authorities.

What does Rezafungin target?

Rezafungin is an antifungal agent that works by inhibiting the synthesis of an essential component of the fungal cell wall. This mechanism is shared with other echinocandin drugs, which are used to treat invasive fungal infections like candidemia.

Who makes Rezafungin?

Rezafungin is being developed by Cidara Therapeutics, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol CDTX. The company is focused on developing novel therapies for serious infectious diseases.

What phase is Rezafungin in?

Rezafungin is in Phase 3 clinical development. It has completed one Phase 3 trial, and it remains an investigational drug, meaning it has not yet been approved for commercial use.

What clinical trials is Rezafungin in?

Rezafungin has been studied in a Phase 3 clinical trial with the identifier NCT03667690. This randomized, double-blind, active-controlled study compared rezafungin to caspofungin in 199 subjects with candidemia and/or invasive candidiasis, and it has been completed.

Is Rezafungin the same as any other drug?

Rezafungin is a distinct investigational drug and is not known by any other names. It is being studied as a potential treatment for candidemia, and it is not the same as other approved antifungal medications.
