JERSEY CITY, N.J., Aug. 13, 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 second quarter ended June 30, 2025.

“We are excited about the continued progress of our second-generation fungerp candidate, SCY-247, and we anticipate announcing SAD/MAD data from our ongoing Phase 1 study of oral SCY-247 this quarter,” said David Angulo, M.D., President and Chief Executive Officer. “We also continue to work towards resolving our dispute with GSK as it relates to the payment of the milestones associated with the restart and continuation of the MARIO study. As these discussions continue, GSK has emphasised that it remains committed to the commercialization of Brexafemme in vulvovaginal candidiasis. Per GSK’s request, we have initiated transfer of the New Drug Application for Brexafemme to them which will enable GSK to initiate regulatory interactions to discuss the relaunch of the product.”

Ibrexafungerp / GSK Developments

• SCYNEXIS is working to transfer the BREXAFEMME NDA to GSK by the end of 2025. Once this transfer has been completed, GSK will be able to initiate regulatory interactions with the U.S. Food and Drug Administration (FDA) in 2026 to discuss the relaunch of BREXAFEMME for vulvovaginal candidiasis (VVC) and refractory vulvovaginal candidiasis (rVVC) in the U.S. market.

• On May 28, 2025, the Company announced that the first new patient was dosed in the Phase 3 MARIO study following the lifting of the FDA clinical hold. Resumption of dosing in this study triggers a $10 million milestone payment from GSK. An additional $20 million milestone will be triggered upon the six month anniversary of the resumption of dosing; as previously disclosed GSK disputes these milestone payments, and the Company continues to work towards reaching an agreement with GSK to resolve this matter.

• In late April, the FDA notified SCYNEXIS that the clinical hold on ibrexafungerp had been lifted and concluded that the Phase 3 MARIO study could resume. The MARIO study is a Phase 3 trial evaluating ibrexafungerp for the treatment of invasive candidiasis.

SCY-247 Development Program

• Presented positive preclinical efficacy data on its second-generation fungerp candidate SCY-247 at the ESCMID meeting, which took place in Vienna, Austria from April 11-15, 2025. Data from the four presentations continues to build upon SCY-247’s positive profile illustrating its unique attributes in the fight against difficult-to-treat fungal infections, including its potent antifungal activity against multi drug-resistant fungi.
• The Company remains on track to report Phase 1 SAD/MAD data for the oral formulation of SCY-247 in Q3 2025;

Corporate Updates

• On July 30, 2025 the United States District Court, District of New Jersey granted the Company’s motion to dismiss a securities class action lawsuit that was filed by Brian Feldman in November 2023 against the Company and certain of the Company’s executives. Should the plaintiff decide to appeal or file an amended complaint, he has 30 days to do so.

Second Quarter 2025 Financial Results

For the three months ended June 30, 2025 and 2024, revenue primarily consisted of $1.4 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 June 30, 2025, was $7.1 million compared to $6.8 million for the same period in 2024. The increase of $0.3 million, or 5%, for the three months ended June 30, 2025, was primarily driven by an increase of $0.3 million in chemistry, manufacturing, and controls (CMC) expense, an increase of $0.4 million in preclinical expense, and an increase of $0.2 million in clinical expense, offset in part by a decrease of $0.2 million in salary expense and a net decrease of $0.4 million in other research and development expense.

Selling, general and administrative expenses for the three months ended June 30, 2025, increased to $3.8 million compared to $3.2 million for the three months ended June 30, 2024. The increase of $0.6 million, or 20%, for the three months ended June 30, 2025, was primarily driven by an increase of $0.4 million in professional fees.

Total other income was $2.7 million for the three months ended June 30, 2025, versus total other expense of $5.2 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 June 30, 2025 and 2024, we recognized a gain of $2.2 million and a loss of $5.8 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 June 30, 2025 was $6.9 million, or $(0.14) basic loss per share, compared to net loss of $14.5 million, or $(0.30) basic loss per share for the same period in 2024.

Cash Balance

Cash, cash equivalents and investments totaled $46.5 million on June 30, 2025, compared to $75.1 million on December 31, 2024. Based upon the company’s current operating plan, SCYNEXIS believes that its existing cash, cash equivalents and investments provide a cash runway into Q4 2026.

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 and is in late-stage development for invasive candidiasis. The next generation fungerp, SCY-247, is currently in the late stages of a Phase 1 clinical study.

(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) approved BREXAFEMME® (ibrexafungerp tablets) in June 2021, for its first indication in vulvovaginal candidiasis (VVC), followed by a second indication in November 2022, for reduction in the incidence of recurrent VVC. Late-stage clinical investigation of ibrexafungerp for the treatment of life-threatening invasive fungal infections in hospitalized patients is ongoing. 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.
