JERSEY CITY, N.J., Aug. 10, 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 second quarter ended June 30, 2026, and provided a corporate update highlighting the initiation of a Phase 1 study of SCY-770 in support of its planned Phase 2 trial in Autosomal Dominant Polycystic Kidney Disease (ADPKD).

“The initiation of our Phase 1 study marks an important milestone in the advancement of SCY-770 and our commitment to developing a potentially transformative treatment for patients living with ADPKD, a disease that affects about 140,000 patients in the United States alone,” said David Angulo, M.D., President and Chief Executive Officer of SCYNEXIS. “SCY-770 is a highly selective orally available direct AMPK activator designed to address multiple underlying drivers of cyst growth and disease progression. Supported by compelling preclinical data and a well-characterized safety profile, we believe that SCY-770 has the potential to offer a differentiated therapeutic approach for this underserved patient population. We are encouraged by the progress of the program and remain on track to initiate our Phase 2 proof-of-concept trial later this year.”

“We are also progressing development of our next-generation antifungal, SCY-247. We completed dosing patients in the Phase 1 study of the IV formulation, and we are on track for topline data in Q3 of this year. With a strong balance sheet and cash runway into 2029, we remain confident in our ability to execute across our pipeline and deliver on our near-term milestones,” continued Dr. Angulo.

SCY-770 Development Program Update

On June 30, 2026, SCYNEXIS announced the initiation of a Phase 1 study of SCY-770, a first-in-class, potent and direct AMP-activated protein kinase (AMPK) activator. The study is characterizing the food-effect and defining the pharmacokinetics of two dosing regimens of SCY-770 to support dose selection for the planned Phase 2 study in ADPKD patients. Top line data are expected in the third quarter of 2026.

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 early efficacy readout in the second half of 2027.

SCY-770 has been granted Orphan Drug Designation by the FDA for the treatment of ADPKD and has been evaluated in several Phase 1 trials and one Phase 2a trial in patients with nonalcoholic fatty liver disease (NAFLD), with a well-characterized safety profile across more than 270 clinical trial participants.

SCY-247 Development Program Update

Dosing has been completed in the Phase 1 study of the IV formulation of SCY-247 and topline data are expected in the third quarter of 2026. SCYNEXIS continues to explore non-dilutive funding opportunities to support the further development of SCY-247.

Ibrexafungerp / GSK Update

The Company believes GSK is committed to 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.

Second Quarter 2026 Financial Results

Research and development expenses for the three months ended June 30, 2026, were $3.9 million compared to $7.1 million for the same period in 2025. The decrease of $3.3 million, or 46%, was primarily driven by a decrease of $1.6 million in chemistry, manufacturing, and controls (CMC) expense, a $0.8 million decrease in preclinical expense, a $0.5 million decrease in clinical expense and a net decrease of $0.4 million in other research and development expense. . SG&A expenses for the three months ended June 30, 2026, increased to $4.1 million compared to $3.8 million for the same period in 2025. The increase of $0.3 million, or 9%, was primarily due to the increase of $0.3 million in professional fees.

Total other income was $15.2 million for the three months ended June 30, 2026, versus total other income of $2.7 million for the same period in 2025. The variance is mainly due to the fair value adjustment related to the warrant liabilities. For the three months ended June 30, 2026 and 2025, SCYNEXIS recognized gains of $14.2 million and $2.2 million, respectively, in the fair value adjustment related to the warrant liabilities primarily due to the decrease in our stock price during the respective periods.

Cash Balance

Cash, cash equivalents and investments totaled $71.1 million on June 30, 2026, compared to $56.3 million on December 31, 2025.

On March 31, 2026, SCYNEXIS announced that it entered into a securities purchase agreement with certain new and existing institutional and accredited investors for net proceeds of $36.9 million, after deducting placement agent fees and transaction-related expenses, and up to an additional $52.2 million in gross proceeds if associated common warrants are fully exercised. The private placement closed on April 1, 2026. The company expects its current cash position to be sufficient to fund operations into 2029.

About SCY-770

SCY-770, a novel and highly selective, direct Adenosine Monophosphate (AMP)-activated protein kinase (AMPK) activator, is being developed as a disease-modifying therapy for ADPKD, a progressive genetic kidney disorder and the leading genetic cause of end-stage renal disease, affecting approximately 140,000 diagnosed patients in the United States. AMPK activation suppresses the mTOR and cAMP signaling pathways that drive cyst cell proliferation and fluid secretion in ADPKD, providing a mechanistically differentiated approach to slowing disease progression. SCY-770 has been evaluated in several Phase 1 trials and one Phase 2a trial in patients with nonalcoholic fatty liver disease (NAFLD). Compelling preclinical pharmacology data supports its potential utility in ADPKD. The Company aims to develop SCY-770 with the goal of reducing cyst growth and disease progression and improving patient quality of life. SCY-770 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of ADPKD.
