JERSEY CITY, N.J., Nov. 05, 2026 (GLOBE NEWSWIRE) — SCYNEXIS, Inc. (NASDAQ: SCYX) (“SCYNEXIS” or the “Company”), a clinical-stage biotechnology company dedicated to advancing innovative solutions for severe rare diseases, today reported financial results for the third quarter ended September 30, 2026, and provided a corporate update highlighting the completion of a Phase 1 study of SCY-770 in support of its planned Phase 2 program in Autosomal Dominant Polycystic Kidney Disease (ADPKD), the award of a BARDA contract providing up to approximately $214 million in non-dilutive funding to advance the development of SCY-247, and the completion of the Phase 1 study of intravenous SCY-247.

“We are working to advance SCY-770 into a Phase 2 proof-of-concept clinical trial by the end of this year. We believe that our highly selective and direct AMP-activated protein kinase (AMPK) activator has the potential to be a differentiated therapy for ADPKD, a serious progressive disease that affects about 140,000 people in the United States alone,” said David Angulo, M.D., President and Chief Executive Officer of SCYNEXIS. “In our Phase 1 study, SCY-770 was well tolerated at higher doses than previously evaluated, and the pharmacokinetic and safety data generated will support dose selection for planned Phase 2 trial. Our goal is to bring patients a new, well-tolerated oral treatment option for a disease with significant unmet need and limited therapeutic options.”

“While we remain focused on SCY-770, our recent partnership with BARDA enables us to advance SCY-247, a Phase 2-ready program, for the treatment and prevention of serious invasive fungal infections while leveraging our existing infrastructure and capabilities. With Phase 1 studies of both the intravenous and oral formulations of SCY-247 now complete, we are advancing preparation for the next stage of development and expect to initiate a Phase 2 study in 2027, subject to regulatory agreement. We have also strengthened our leadership team with the additions of Sanjay Subramanian as Chief Financial Officer, and Todd Minga as Senior Vice President of Research and Development. Their experience in capital markets, nephrology and drug development for chronic kidney disease will be invaluable as we execute across our pipeline. With a strong balance sheet and cash runway into 2029, we remain confident in our ability to deliver on our upcoming milestones for patients and shareholders alike,” continued Dr. Angulo.

SCY-770 Development Program Update

• On October 6, 2026, SCYNEXIS announced completion of a Phase 1 study of SCY-770, a first-in-class, selective and direct AMPK activator. The study enrolled 25 healthy participants across three cohorts: the initial cohort received a single 500 mg dose under fed and fasted conditions, and subsequent cohorts received 750 mg once daily or 500 mg twice daily, or placebo, for seven days. SCY-770 was well tolerated across all cohorts and demonstrated a safety profile consistent with prior clinical experience. Pharmacokinetic data from this and prior studies will inform dose selection for the Phase 2 study in ADPKD patients.
• SCYNEXIS remains on track to initiate its Phase 2 proof-of-concept study of SCY-770 in ADPKD patients in Q4 2026, with an anticipated interim analysis in Q4 2027.

SCY-247 Development Program Update

• On September 28, 2026, SCYNEXIS announced that it was awarded a BARDA contract providing up to approximately $214 million in non-dilutive funding, if all options are exercised, to advance the development of SCY-247, with approximately $18.5 million in the initial base period to support advancement of oral and intravenous SCY-247 into a Phase 2 trial in patients with invasive candidiasis. The award is structured as a cost-share arrangement, and the Company expects to fund its share of near-term program costs for SCY-247 within its existing operating plan.
• On October 22, 2026, SCYNEXIS announced topline results from its Phase 1 single and multiple ascending dose trial of intravenous (IV) SCY-247 in 56 healthy participants. IV SCY-247 was generally well tolerated, with no drug-related serious adverse events, and once-daily IV doses of 50 mg or higher achieved exposures at or above the efficacy target identified in murine models of invasive candidiasis.
• The Company expects to initiate Phase 2 development of SCY-247 in oral and IV formulations in 2027, subject to regulatory agreement.

Activities for this project may be funded in whole or in part with federal funds from the U.S. Department of Health and Human Services (HHS); Administration for Strategic Preparedness and Response (ASPR); Center for the Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50126C00007.

Ibrexafungerp / GSK Update

• The Company believes that GSK continues making progress toward the relaunch of BREXAFEMME. Following the relaunch, SCYNEXIS has the potential to receive up to approximately $146 million in annual net sales milestones as well as net royalties in the low to mid-single digit range.

Leadership and Board Updates

• Sanjay S. Subramanian, MBA, was appointed Chief Financial Officer, effective September 9, 2026. Mr. Subramanian brings more than 20 years of finance, capital markets, business development and operational leadership experience across the biotechnology, pharmaceutical and healthcare sectors, most recently as Chief Financial Officer and Head of Business Development at Inozyme Pharma.

Third Quarter 2026 Financial Results

Research and development expenses for the three months ended September 30, 2026, were $6.2 million compared to $5.5 million for the same period in 2025. The increase of $0.7 million, or 14%, was primarily driven by an increase of $1.7 million in clinical expense, offset in part by a $0.6 million decrease in preclinical expense, and a $0.4 million decrease in chemistry, manufacturing, and controls (CMC) expense.

SG&A expenses for the three months ended September 30, 2026, increased to $3.6 million compared to $3.3 million for the same period in 2025. The increase of $0.3 million, or 8%, was primarily due to the increase of $0.2 million in professional fees.

Total other income was $1.3 million for the three months ended September 30, 2026, versus total other expense of $0.2 million for the same period in 2025. The variance is mainly due to other income recognized for certain research and development tax credits in the three months ended September 30, 2026.

Cash Balance

Cash, cash equivalents and investments totaled $63.2 million on September 30, 2026, compared to $71.1 million on June 30, 2026. The decrease in cash, cash equivalents, and investments was primarily due to the continued development costs for SCY-770 and SCY-247. This cash position is expected to be sufficient to continue operations into 2029.

About ADPKD

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a genetic disease caused by mutations of the PKD1 or PKD2 genes which encode polycystin complex 1 (PC1) or polycystin complex 2 (PC2) proteins, critical for normal tubular epithelial cell function. Patients develop fluid-filled cysts in their kidneys that progressively impair kidney function, with more than 50% reaching end-stage renal failure by the age of 60 requiring renal replacement therapies (e.g., dialysis or transplant). The U.S. prevalence of ADPKD is estimated to be 140,000 people, with approximately 6,000 new cases diagnosed each year. ADPKD currently has only one approved therapy, Jynarque (tolvaptan), which achieved approximately $1.5 billion in U.S. sales in 2024 despite limited patient uptake due to safety, tolerability, and monitoring requirements.

About SCY-770

SCY-770 is a novel, highly selective, oral direct activator of adenosine monophosphate-activated protein kinase (AMPK) being developed as a potential disease-modifying therapy for autosomal dominant polycystic kidney disease (ADPKD), a progressive genetic disorder characterized by significant unmet medical need. By activating AMPK, SCY-770 targets multiple pathways implicated in disease progression, including mTOR and cAMP signaling, which are known to drive cyst growth and fluid secretion. In addition, AMPK activation is associated with reduction in inflammation and fibrosis while improving cellular metabolism, offering a differentiated, multi-mechanistic approach to address the underlying drivers of ADPKD. SCY-770 has been evaluated across multiple clinical trials in approximately 300 participants to date. SCY-770 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of ADPKD.

About SCY-247

SCY-247 is a second-generation triterpenoid (fungerp) antifungal candidate being developed for the treatment of invasive candidiasis and the prevention of invasive fungal diseases. As a member of a novel structural class, SCY-247 has a differentiated mechanism of action from existing antifungal classes and has demonstrated in vitro activity against a broad range of fungal pathogens, including strains resistant to currently available therapies. SCY-247 has been granted Orphan Drug, Qualified Infectious Disease Product (QIDP) and Fast Track designations by the U.S. Food and Drug Administration. SCYNEXIS is developing both oral and intravenous (IV) formulations of SCY-247. Recently, SCYNEXIS was awarded a BARDA contract (75A50126C00007) providing up to approximately $214 million in non-dilutive funding, if all options are exercised, to advance the development of SCY-247.
