Percentage of participants with complete resolution of signs and symptoms (total VSS score of 0) with no additional antifungal therapy required. The vulvovaginal signs and symptom (VSS) scale ranges from 0 to 18, with higher scores being worse.
Efficacy as measured by the percentage of subjects with documented Clinical Success.
The percentage of subjects with clinical cure (complete resolution of signs and symptoms) at the test-of-cure (TOC) visit
The percentage of participants who achieve Global Response (defined as complete or partial response) as determined by the DRC at disease specific timepoints by fungal disease. Global Response is measured by participant survival and overall effect of treatment on the disease. Complete response: Survival, all attributable signs/symptoms (including radiological) resolved and myoclogical eradication of disease; Partial response: Survival, improvement of attributable signs/symptoms (including radiological). Disease specific timepoints: End of Treatment (EoT) for invasive candidiasis, EoT or Day 84 for Chronic Mucocutaneous Candidiasis, Test of Cure (TOC) for Vulvovaginal Candidiasis, EoT or Day 90 for Chronic Pulmonary Aspergillosis, EoT or Day 90 Allergic Bronchopulmonary Aspergillosis and EoT for all other diseases.
To determine the levels of SCY-078 in breast milk in ng/mL, starting pre-dose (Baseline) on Day 1 until 108 hours post first dose. Concentrations of SCY-078 in milk is measured pre-dose, and in milk collected at the following post-dose intervals: 0-2 hours, 2-4 hours, 4-8 hours, 8-12 hours, 12-18 hours, 18-24 hours, 24-36 hours, 36-48 hours, 48-72 hours and 72-108 hours.
To measure the levels of SCY-078 in plasma at pre-dose (0 hours), 2, 6, 8 12 hours post dose (prior to the second dose) and 24, 36, 48, 72 and 108 hours post first dose.
Mass balance recovery of total radioactivity in urine, faeces and all excreta (urine and faeces): cumulative recovery (CumAe) and cumulative recovery expressed as a percentage of the dose (Cum%Ae)
Determination of primary metabolites using liquid chromatography-radio-detection
Area under the plasma concentration versus time curve (AUC) will be estimated where possible
Area under the plasma concentration versus time curve (AUC) of total radioactivity in blood where possible
Peak Plasma Concentration (Cmax) of Ibrexafungerp will be estimated
Amount recovered expressed as a percentage of the dose administered

Ibrexafungerp is an investigational small molecule being developed for fungal infections, including acute vulvovaginal candidiasis, recurrent vulvovaginal candidiasis, invasive candidiasis, and candida vulvovaginitis. It is being studied as an oral treatment for these conditions.
Ibrexafungerp is being developed by SCYNEXIS, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol SCYX. The company is conducting clinical trials to evaluate the drug's safety and efficacy for fungal infections.
Ibrexafungerp is in Phase 3 clinical development. It has completed two Phase 3 trials for acute vulvovaginal candidiasis and one Phase 3 trial for recurrent vulvovaginal candidiasis, along with a Phase 1 study. It remains investigational and is not yet approved.
Ibrexafungerp has completed several clinical trials, including NCT03734991 and NCT03987620 for acute vulvovaginal candidiasis, NCT04029116 for recurrent vulvovaginal candidiasis, and NCT04307082, a Phase 1 ADME study in healthy male subjects. All trials are completed.
Ibrexafungerp is not FDA approved. It is an investigational drug currently in Phase 3 clinical development for fungal infections. The completed trials include placebo-controlled studies in vulvovaginal candidiasis, but regulatory approval has not been granted.
Yes, ibrexafungerp is also known as SCY-078. Clinical trial titles for the drug refer to it as oral ibrexafungerp (SCY-078), confirming that both names refer to the same investigational antifungal agent.
