JERSEY CITY, N.J., May 15, 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 first quarter ended March 31, 2025.

“The lifting of the clinical hold for ibrexafungerp was an important achievement for our company. While seeking to resolve the disagreement with GSK, we are moving forward with the Phase 3 MARIO study. Our second-generation fungerp candidate, SCY-247, continues to progress, with Phase 1 study results expected in the upcoming months,” said David Angulo, M.D., President and Chief Executive Officer.

“SCYNEXIS remains committed to developing novel antifungal solutions to the rising threat of deadly fungal infections including invasive candidiasis for which there are limited treatment options and significant concerns for emergence of resistances, as highlighted by the WHO in their call to industry and other parties for research, development and public health action in this area of unmet need,” he added.  

Ibrexafungerp / GSK Developments

• 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. Subsequently GSK notified SCYNEXIS of their intention to immediately terminate the study. SCYNEXIS does not believe that GSK currently has the right to unilaterally terminate the MARIO study under the license agreement with GSK (GSK License Agreement) and is seeking to resolve this disagreement. Meanwhile, SCYNEXIS is resuming the MARIO study with the goal of having subjects enrolled in the coming weeks. While at this time it is too early to say how this disagreement regarding the MARIO study may be resolved, GSK has reiterated its commitment to continued collaboration regarding other aspects of the GSK License Agreement, including with respect to the commercialization of BREXAFEMME for the VVC and rVVC indications.

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.
• In December 2024, the Company initiated a randomized, double-blind, placebo-controlled Phase 1 study of single and multiple ascending doses of oral SCY-247 in approximately 100 healthy subjects. The primary endpoint is safety and tolerability, and the secondary endpoint is pharmacokinetics. Single ascending and multiple ascending dose data are expected in Q3 2025.

First Quarter 2025 Financial Results

For the three months ended March 31, 2025 and 2024, revenue primarily consists of $0.3 million and $1.4 million, respectively, in license agreement revenue associated with the GSK License Agreement.

Research and development expense for the three months ended March 31, 2025, was $5.1 million compared to $7.2 million for the same period in 2024. The decrease of $2.1 million, or 29%, for the three months ended March 31, 2025, was primarily driven by a decrease of $1.6 million in chemistry, manufacturing, and controls expense, a decrease of $0.8 million in clinical expense, and a net decrease in other research and development expense of $0.1 million, offset in part by an increase of $0.4 million in preclinical expense.

SG&A expense for the three months ended March 31, 2025, remained consistent with the prior comparable period at $3.7 million.

Total other income was $3.2 million for the three months ended March 31, 2025, versus total other income of $10.5 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 March 31, 2025 and 2024, we recognized gains of $2.9 million and $9.6 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 March 31, 2025 was $5.4 million, or $(0.11) basic loss per share, compared to net income of $0.4 million, or $0.01 basic income per share for the same period in 2024.

Cash Balance

Cash, cash equivalents and investments totaled $53.8 million on March 31, 2025, compared to $75.1 million on December 31, 2024. The Company repaid $14.0 million of March 2019 convertible notes due in March 2025 in the first quarter. Based upon the company’s current operating plan, SCYNEXIS believes that its existing cash, cash equivalents and investments provide a cash runway into Q3 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 of development for invasive candidiasis and other indications. SCY-247 is a next generation fungerp in pre-clinical development for the treatment of life-threatening and often multi-drug-resistant fungal diseases including Candida auris infections.

About SCYNEXIS

SCYNEXIS, Inc. (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.
