Announcement
SCYNEXIS, Inc. announced that the U.S. Food and Drug Administration ("FDA") has granted the Company Qualified Infectious Disease Product (QIDP) and Fast Track Designations for its second-generation triterpenoid antifungal therapy, SCY-247.
AI Summary
SCYNEXIS announced that the U.S. Food and Drug Administration granted Qualified Infectious Disease Product (QIDP) and Fast Track designations for its second-generation triterpenoid antifungal, SCY-247. The company said the QIDP status will ensure at least 10 years of market exclusivity for SCY-247 following approval. SCY-247 is being developed to treat serious, drug-resistant fungal infections and has shown activity against hard-to-treat pathogens such as Candida auris and echinocandin-resistant C. glabrata in preclinical work and early human studies.
The Fast Track designation can speed development by enabling more frequent FDA interactions, rolling review of applications, and potential eligibility for accelerated approval or priority review. SCYNEXIS plans to advance SCY-247 into additional clinical studies in 2026 and is pursuing funding to support the program as it seeks to address the growing public health threat from resistant fungal infections.

Announcement
SCYNEXIS, Inc. announced positive results from a Phase 1 study of SCY-247, its second-generation triterpenoid antifungal under development for the treatment and prevention of invasive fungal infections with the potential to provide the therapeutic advantages of both an oral and IV formulation.
AI Summary
SCYNEXIS, Inc. announced positive results from a Phase 1 study of SCY-247, its second-generation triterpenoid antifungal. Designed for oral and IV use against invasive fungal infections, SCY-247 reached target drug levels at lower doses than its first-generation compound with no safety concerns or dose-limiting toxicities.
The study tested single ascending doses from 50 mg to 900 mg and multiple ascending doses from 50 mg to 300 mg once daily for seven days in healthy volunteers. Sixty-six participants received SCY-247 and 22 received placebo. SCY-247 was well tolerated, with only mild to moderate headaches and diarrhea reported, and no serious adverse events.
Pharmacokinetic data showed rapid absorption (Tmax 3–7 hours) and dose-proportional increases in exposure (Cmax and AUC). The 200 mg and 300 mg daily doses met or exceeded target exposures based on preclinical models of resistant fungi. These results support continued clinical development of SCY-247 for invasive fungal infections.

Announcement
SCYNEXIS, Inc. announced multiple upcoming presentations highlighting data on the Company's second-generation fungerp drug candidate, SCY-247, at the upcoming 12th Congress on Trends in Medical Mycology (TIMM-12), which is scheduled to take place from September 19th to 22nd, 2025, in Bilbao, Spain.
AI Summary
SCYNEXIS will present six studies of its second-generation antifungal SCY-247 at the TIMM-12 Congress, taking place September 19–22, 2025, in Bilbao, Spain. An oral session will show SCY-247’s potent in vitro activity against Candida auris strains, including FKS1 echinocandin-resistant isolates, with lower MICs than existing drugs.
Poster sessions will highlight SCY-247’s broad antifungal spectrum. Data cover uniform activity against diverse Candida species with no cross-resistance to echinocandins, strong efficacy against multidrug- and pandrug-resistant C. auris, and in vitro and in vivo potency against resistant Candida glabrata and Aspergillus species.
Another poster will report once- and twice-daily oral SCY-247’s ability to reduce kidney fungal burden in a murine C. auris model. SCYNEXIS expects to report Phase 1 Single Ascending Dose/Multiple Ascending Dose (SAD/MAD) oral trial results in Q3 2025, marking a key step toward new treatments for life-threatening fungal infections.

Announcement
SCYNEXIS, Inc. announced that patient dosing has resumed in the Phase 3 MARIO study, which is an innovative study to investigate oral ibrexafungerp as a potential step-down antifungal therapy following IV echinocandin for invasive candidiasis, a life-threatening infection.
AI Summary
SCYNEXIS, Inc. announced the resumption of patient dosing in its Phase 3 MARIO study after the FDA lifted a clinical hold. The study is testing oral ibrexafungerp as a potential step-down antifungal therapy after patients have received IV echinocandin for invasive candidiasis, a life-threatening infection. New clinical supplies were produced at a different site to address contamination concerns and meet updated FDA standards.
If the trial is successful and approved by the FDA, the new oral treatment could offer healthcare providers an important alternative to IV-only echinocandin therapies, improving patient care for invasive fungal infections. The restart of dosing also triggers a $10 million milestone payment from partner GSK, with an additional $20 million expected in six months, although there is a disagreement between the companies over these payments.
