Ibrexafungerp in the Treatment of Vulvovaginal Candidiasis

Abstract

Objective: To review the pharmacology, efficacy, and safety of ibrexafungerp in the management of vulvovaginal candidiasis (VVC).

Data sources: Literature was sought using PubMed (1966-February 2022) and EMBASE (1973-February 2022), and clinicaltrials.gov. Search terms included ibrexafungerp, SCY-078, and VVC.

Study selection and data extraction: All studies including humans and published in English with data assessing the efficacy and safety of ibrexafungerp for the treatment of VVC were evaluated.

Data synthesis: A phase 2 dose-finding study found ibrexafungerp had similar efficacy to fluconazole in the clinical cure of VVC (51.9% vs 58.3%, respectively). Two phase 3 clinical trials demonstrated ibrexafungerp had statistical superiority over placebo for clinical cure in moderate to severe VVC (P < 0.001 and P = 0.023, respectively). The most frequently reported adverse reactions in the clinical trials were gastrointestinal-related symptoms. To date, data comparing efficacy of ibrexafungerp and topical imidazoles in the treatment of VVC are nonexistent.

Relevance to patient care and clinical practice: Topical imidazoles and oral fluconazole are effective for the treatment of uncomplicated VVC. Due to increased resistance, limited fluconazole coverage for non-Candida albicans species, and potential for significant drug interactions associated with fluconazole use, alternative treatments for VVC are needed. Ibrexafungerp is a new oral triterpenoid antifungal agent indicated for the treatment of VVC. Additional clinical trials are needed to evaluate long-term safety data as well as efficacy and safety in specialty populations.

Conclusion: Ibrexafungerp, a recently approved triterpenoid antifungal agent, is an effective and well-tolerated option for the treatment of VVC.
