• Following the positive SAD/MAD data results announced in September for SCY-247, its second-generation fungerp, the Company expects to initiate a Phase 1 study with the IV formulation and a Phase 2 study for the treatment of invasive candidiasis. The Company aims to release clinical proof of concept data in invasive candidiasis in 2026 and is exploring non-dilutive funding opportunities to support the development of SCY-247.
  
  

• GSK remains committed to the relaunch of BREXAFEMME^® with activities ongoing to transfer the NDA before the end of the year.

JERSEY CITY, N.J., Nov. 05, 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 reported financial results for the third quarter ended September 30, 2025.

“Over the last several weeks, SCYNEXIS realized two significant achievements that we believe position our company for significant growth and success,” said David Angulo, M.D., President and Chief Executive Officer. “First, we announced the positive SAD/MAD data for our second-generation fungerp drug candidate, SCY-247, demonstrating that orally administered SCY-247 was well tolerated and achieved the estimated efficacy exposure at doses lower than the first generation fungerp (ibrexafungerp). We are excited about the favorable tolerability and pharmacokinetics of SCY-247 and look forward to commencing a Phase 2 study in invasive candidiasis, aiming to release proof of concept data in 2026. Secondly, we announced a successful resolution of our disagreement with GSK, which led to the one time payments of $24.8 million to SCYNEXIS which we will receive in Q4 of 2025. This influx of new capital coupled with our cash and investments on hand, results in a cash runway of more than two years, including the anticipated cost of SCY-247 development activities.”

Ibrexafungerp / GSK Update

• On October 15, 2025, the Company announced that it would receive a one-time payment of $24.8 million from GlaxoSmithKline Intellectual Property (No. 3) Limited (GSK) as part of a resolution of the disagreement with GSK related to the restart of the Phase 3 MARIO study on invasive candidiasis. SCYNEXIS also announced that it would promptly commence appropriate wind-down activities associated with the termination of the MARIO study.
  

SCY-247 Development Program

• On September 30, 2025, the Company announced positive results from a Phase 1 SAD/MAD 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.

  • SCY-247 was generally well tolerated with no dose limiting toxicities observed

  • SCY-247 was able to achieve target exposures at doses lower than our first-generation fungerp

  • Safety, tolerability, and pharmacokinetic profile support the continued clinical development of SCY-247

• After positive Phase 1 data, the Company intends to progress the development of SCY-247 towards addressing significant unmet needs in the antifungal space that also represent attractive commercial opportunities. SCYNEXIS anticipates initiating a Phase 1 study with the intravenous (IV) formulation of SCY-247 in Q1 2026. The clinical proof-of-concept Phase 2 study is planned to start using the oral formulation of SCY-247 in patients with invasive candidiasis and subsequent stages of development are anticipated to include studies adequate to support an invasive candidiasis treatment indication, as well as evaluating SCY-247 for the prevention of invasive fungal diseases in patients at high risk. Phase 2 proof-of-concept data are expected to be available in 2026. The Company is exploring non-dilutive funding opportunities to support the development of SCY-247.
  

• On September 4, 2025, SCYNEXIS announced multiple presentations highlighting data on the Company’s second-generation fungerp drug candidate, SCY-247, at the 12^th Congress on Trends in Medical Mycology (TIMM-12), which took place from September 19^th to 22^nd, 2025, in Bilbao, Spain.

  • An oral presentation featured data demonstrating SCY-247 in vitro activity against C. auris strains, including isolates with mutations commonly associated with echinocandin-resistance

  • Additional poster presentations highlighted SCY-247’s broad spectrum of antifungal activity, against Candida species, including multidrug- and pandrug-resistant C. auris and Aspergillus species.
    

Third Quarter 2025 Financial Results

For the three months ended September 30, 2025 and 2024, revenue primarily consisted of $0.3 million and $0.7 million, respectively, in license agreement revenue associated with the GSK License Agreement.

Research and development expenses for the three months ended September 30, 2025, was $5.5 million compared to $8.1 million for the same period in 2024. The decrease of $2.6 million, or 33%, for the three months ended September 30, 2025, was primarily driven by a decrease of $1.4 million in chemistry, manufacturing, and controls (CMC) expense, a decrease of $0.2 million in preclinical expense, a decrease of $0.2 million in clinical expense, a $0.2 million decrease in salary expense, a $0.3 million decrease in stock-based compensation expense, and a net decrease of $0.3 million in other research and development expense.

Selling, general and administrative expenses for the three months ended September 30, 2025, increased to $3.3 million compared to $2.9 million for the three months ended September 30, 2024. The increase of $0.4 million, or 13%, for the three months ended September 30, 2025, was primarily driven by an increase of $0.3 million in professional fees.

Total other expense was $0.2 million for the three months ended September 30, 2025, versus total other income of $7.1 million for the same period in 2024. The variance is mainly due to the fair value adjustment related to the warrant liabilities. For the three months ended September 30, 2025 and 2024, we recognized a loss of $0.6 million and a gain of $6.8 million, respectively, on the fair value adjustment for warrant liabilities primarily due to the changes in our stock price during the periods.

Net loss for the three months ended September 30, 2025 was $8.6 million, or $(0.17) basic loss per share, compared to net loss of $2.8 million, or $(0.06) basic loss per share for the same period in 2024.

About Triterpenoid Antifungals

Triterpenoid antifungals (also known as “fungerps”) are a novel class of structurally distinct glucan synthase inhibitors that combine the well-established activity of glucan synthase inhibitors with the potential flexibility of having oral and intravenous (IV) formulations. They have demonstrated broad-spectrum antifungal activity against multidrug-resistant pathogens, including azole- and echinocandin-resistant strains. Ibrexafungerp is the first representative of this novel class of antifungal agents. Ibrexafungerp, formerly known as SCY-078, is currently approved in the U.S. for the treatment of vulvovaginal candidiasis. The next generation fungerp, SCY-247, is currently in Phase 1 stage of clinical development. Additional analogs of the fungerp class of compunds are in pre-clinical stages of development.

(NASDAQ: SCYX) is a biotechnology company pioneering innovative medicines to help millions of patients worldwide overcome and prevent difficult-to-treat infections that are becoming increasingly drug-resistant. SCYNEXIS is developing the company’s proprietary antifungal platform “fungerps.” Ibrexafungerp, the first representative of this novel class, has been licensed to GSK. The U.S. Food and Drug Administration (FDA) has approved BREXAFEMME® (ibrexafungerp tablets) for the treatment of vulvovaginal candidiasis (VVC) and for reduction in the incidence of recurrent VVC. Additional antifungal assets from this novel class are currently in clinical, pre-clinical and discovery phases, including the compound SCY-247. For more information, visit www.scynexis.com.
