JERSEY CITY, N.J., Sept. 04, 2025 (GLOBE NEWSWIRE) -- SCYNEXIS, Inc. (NASDAQ: SCYX ), a biotechnology company pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections, today announced multiple upcoming presentations highlighting data on the Company’s second-generation fungerp drug candidate, SCY-247, at the upcoming 12 th Congress on Trends in Medical Mycology (TIMM-12), which is scheduled to take place from September 19 th to 22 nd , 2025, in Bilbao, Spain.

“Our six presentations at this year’s TIMM-12 Congress highlight the significant potential of SCY-247 to combat difficult, resistant Candida infections, including C. auris ,” said David Angulo, M.D., President and Chief Executive Officer of SCYNEXIS. “We are developing SCY-247 to specifically address one of the most serious and challenging issues in infectious disease, and the data from these presentations provide highly encouraging evidence that SCY-247 has the potential to address these difficult-to-treat and life-threatening fungal infections. Later this quarter, we anticipate reporting results from our Phase 1 SAD/MAD trial of SCY-247, which represents an important next step in further advancing this exciting program.”

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)

Summary: Candida auris is 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 resistant C. auris isolates representing clades I, II, III, IV, and V. Overall, in comparison to the echinocandins, SCY-247 consistently demonstrated lower MICs for C. auris in 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 PhD
Affiliations: Statens Serum Institut
Summary We present the first three months of EUCAST SCY-247 MICs compared to anidulafungin and micafungin MICs of 293 Candida isolates. SCY-247 displayed uniform activity against all Candida species included, with no indication of cross-resistance to the echinocandins.


Title In vitro efficacy of second-generation triterpenoid antifungal, SCY-247 against multidrug- and pandrug-resistant Candida auris
Poster # P053
Session Date Saturday, 20 September 2025
Presentation Start Time
11:15 CET (30 minutes)
Presenting Author Vishnu Chaturvedi, PhD
Affiliations: New York Medical College, Valhalla, New York
Summary: Candida auris is 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-resistant C. auris strains. 300 C. auris isolates, mostly from New York area, were tested against SCY-247 and 10 other antifungal agents. SCY-247 demonstrated potent activity against C. auris including pandrug-resistant isolates.


Title The Novel Second-Generation IV/Oral Triterpenoid SCY-247 Maintains In vitro and In vivo Activity against Resistant Candida glabrata
Poster # P423
Session Date
Saturday, 20 September 2025
Presentation Start Time 11:15 CET (30 minutes)
Presenting Author Nathan Wiederhold, PhD
Affiliations: University of Texas Health Science Center at San Antonio
Summary Candida glabrata is a major cause of invasive candidiasis and is considered a high priority pathogen by the WHO. In vitro susceptibility testing was performed against 29 echinocandin-resistant clinical strains of C. glabrata. SCY-247 maintained in vitro activity against echinocandin-resistant C. glabrata and also demonstrated in vivo efficacy in an invasive candidiasis mice model caused by an echinocandin- and fluconazole-resistant C. glabrata strain.


Title Efficacy of once or twice daily oral SCY-247, a second-generation triterpenoid antifungal, in a murine model of Candida auris infection
Poster #
P426
Theme New antifungal agents
Session Date

Summary
Candida auris is 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 of C. auris infection. SCY-247 demonstrated in vivo efficacy against invasive C. auris candidiasis . 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 vitro activity of SCY-247 and comparators against clinical isolates of Aspergillus spp. and Lomentospora prolificans
Poster #
P427
Theme
New Antifungal Agents

Summary
The aim of this study is to investigate the in vitro activity of SCY-247 against cryptic Aspergillus species and Lomentospora prolificans isolated from clinical samples. A total of 54 clinical isolates were analyzed including cryptic species of Aspergillus (n=48) and Lomentospora prolificans (n=6). SCY-247 activity was compared to 3 marketed antifungals. SCY-247 exhibited low MECs against cryptic Aspergillus species and moderately high MECs against L.prolificans.
