SCY-247 data presentations at TIMM-12:

Title SCY-247, a Novel Second-Generation IV/Oral Triterpenoid Antifungal, Demonstrates In vitro Activity against C. auris, including the majority of FKS1 mutants
Session: Oral Presentation, S15.5S
Session Date: Saturday, September 20, 2025
Presentation Start Time 17:25 Central European Time (CET)(10 minutes)
Presenting Author Eelco Meijer, MD, PhDAffiliations: Canisius-wilhelmina Hospital (CWZ)/Dicoon, Radboudumc-CWZ Center of Expertise for Mycology
Summary: Candida aurisis a public health concern causing large and persistent outbreaks in healthcare institutions, globally. High incidence of resistance to approved antifungals necessitates investigation of novel drugs for future patient care. Here, we performed antifungal susceptibility testing on the investigational compound SCY-247 and other antifungals, including echinocandins anidulafungin and micafungin against 65 unique FKS1 resistantC. aurisisolates representing clades I, II, III, IV, and V. Overall, in comparison to the echinocandins, SCY-247 consistently demonstrated lower MICs forC. aurisin isolates with commonly found FKS1 resistance mutations.
Title Three Months of SCY-247 EUCAST MIC Testing: Uniform Activity Against Candida Species and No Cross-Resistance to Echinocandins
Poster # P052
Session Date Sunday, 21 September 2025
Presentation Start Time 11:15 CET(30 minutes)
Presenting Author Karin Meinike Jørgensen PhDAffiliations: Statens Serum Institut
Summary We present the first three months of EUCAST SCY-247 MICs compared to anidulafungin and micafungin MICs of 293Candidaisolates. SCY-247 displayed uniform activity against allCandidaspecies included, with no indication of cross-resistance to the echinocandins.
Title In vitroefficacy of second-generation triterpenoid antifungal, SCY-247 against multidrug- and pandrug-resistantCandida auris
Poster # P053
Session Date Saturday, 20 September 2025
Presentation Start Time 11:15 CET(30 minutes)
Presenting Author Vishnu Chaturvedi, PhDAffiliations: New York Medical College, Valhalla, New York
Summary: Candida aurisis a newly recognized global health threat by the CDC and WHO. In the USA, the New York –New Jersey metropolitan area remains a hotbed for multidrug- and pandrug-resistantC. aurisstrains. 300C. aurisisolates, mostly from New York area, were tested against SCY-247 and 10 other antifungal agents. SCY-247 demonstrated potent activity againstC. aurisincluding pandrug-resistant isolates.
Title The Novel Second-Generation IV/Oral Triterpenoid SCY-247 MaintainsIn vitroandIn vivoActivity against ResistantCandida glabrata
Poster # P423
Session Date Saturday, 20 September 2025
Presentation Start Time 11:15 CET(30 minutes)
Presenting Author Nathan Wiederhold, PhDAffiliations: University of Texas Health Science Center at San Antonio
Summary Candida glabratais a major cause of invasive candidiasis and is considered a high priority pathogen by the WHO.In vitrosusceptibility testing was performed against 29 echinocandin-resistant clinical strains ofC. glabrata.SCY-247 maintainedin vitroactivity against echinocandin-resistantC. glabrataand also demonstrated in vivo efficacy in an invasive candidiasis mice model caused by an echinocandin- and fluconazole-resistantC. glabratastrain.
Title Efficacy of once or twice daily oral SCY-247, a second-generation triterpenoid antifungal, in a murine model ofCandida aurisinfection
Poster # P426
Theme New antifungal agents
Session Date Sunday, 21 September 2025
Presentation Start Time 11:15 CET(30 minutes)
Presenting Author Mahmoud Ghannoum, PhDAffiliations: Case Western Reserve University and University Hospitals Cleveland Medical Center
Summary Candida aurisis a multidrug resistant fungus exhibiting a 200% increase in incidence in the U.S from 2019 to 2023. The objective was to assess the activity of 7 days of once or twice daily oral SCY-247 treatment in lowering kidney fungal burden in a mouse model ofC. aurisinfection. SCY-247 demonstratedin vivoefficacy against invasiveC. auriscandidiasis.Significant reductions in fungal burden were observed in the kidneys of mice treated with SCY-247 in a dose dependent fashion with similar activity observed between QD and BID doses.
Title In vitroactivity of SCY-247 and comparators against clinical isolates ofAspergillus spp.andLomentospora prolificans
Poster # P427
Theme New Antifungal Agents
Session Date Saturday, 20 September 2025
Presentation Start Time 11:15 CET(30 minutes)
Presenting Author Anastasiia HrynzovskaAffiliations: Mycology Reference Laboratory, National Centre for Mycology, Bogomolets National Medical University
Summary The aim of this study is to investigate thein vitroactivity of SCY-247 against crypticAspergillusspecies andLomentospora prolificansisolated from clinical samples. A total of 54 clinical isolates were analyzed including cryptic species ofAspergillus(n=48) andLomentospora prolificans(n=6). SCY-247 activity was compared to 3 marketed antifungals. SCY-247 exhibited low MECs against crypticAspergillusspecies and moderately high MECs againstL.prolificans.
