JERSEY CITY, N.J., May 11, 2026 (GLOBE NEWSWIRE) -- SCYNEXIS, Inc. (NASDAQ:SCYX), a clinical-stage biotechnology company dedicated to advancing innovative solutions for severe rare diseases, today reported financial results for the first quarter ended March 31, 2026.

"Following our recent acquisition of SCY-770, we plan to initiate a Phase 2 proof-of-concept study in ADPKD patients in Q4 2026 to demonstrate the potential of this highly differentiated molecule, which targets multiple key drivers of disease progression," said David Angulo, M.D., President and Chief Executive Officer. "We would like to thank our existing and new investors who participated in our recent private placement financing. Combined with our existing cash position, this additional capital significantly extends our cash runway to the middle of 2029 approximately one year beyond the anticipated completion of the Phase 2 study for SCY-770."

"As we move ahead with the SCY-770 clinical program, we also continue to make progress with our second generation fungerp, SCY-247. After completion of the Phase 1 studies with the oral formulation of SCY-247, we are now accepting requests for access to this innovative antifungal for patients with limited or no other treatment options via our expanded access program. We also anticipate announcing topline Phase 1 data of the IV formulation of SCY-247 in the third quarter of 2026."

Corporate Update:

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 approximately $37.2 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.

SCY-770 Development Program Update

On March 31, 2026, SCYNEXIS announced that it entered into a definitive agreement with Poxel S.A. to acquire PXL-770 (now SCY-770). SCY-770 is a novel, highly selective, direct AMP-activated protein kinase (AMPK) activator for the treatment of ADPKD, the leading genetic cause of end-stage renal failure. SCY-770 is designed to address many of the underlying drivers of ADPKD by reducing cyst growth and disease progression. SCY-770 is an oral therapy that has been evaluated in eight clinical trials, with a favorable safety profile. SCYNEXIS expects to begin a Phase 2 proof-of-concept study 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 U.S. Food and Drug Administration (FDA).

SCY-247 Development Program Update

Presented 9 papers at the European Society of Clinical Microbiology and Infectious Diseases Conference (ESCMID) in Munich in April, highlighting the positive pre-clinical and Phase 1 clinical data for SCY-247.
In response to patients' needs and physicians' requests, and now with a completed Phase 1 study confirming adequate tolerability and achievement of preliminary target exposures with oral SCY-247, SCYNEXIS is accepting requests under the expanded access program to facilitate access to this innovative antifungal for patients with limited or no other treatment options.
On February 26^th, SCYNEXIS announced the initiation of dosing in a Phase 1 study with the IV formulation of SCY-247, with topline data expected in the third quarter of 2026. SCYNEXIS continues to explore non-dilutive funding opportunities to support the further development of SCY-247.
SCYNEXIS presented data highlighting SCY-247 at the inaugural Interdisciplinary Meeting on Antimicrobial Resistance and Innovation (IMARI), which took place from January 28-30, 2026, in Las Vegas, Nevada. An oral presentation was included in the Plenary session "New Antimicrobial Agents in The Pipeline: Early Clinical Development".
The U.S. Food and Drug Administration (FDA) granted the Company Qualified Infectious Disease Product (QIDP) Fast Track and Orphan Drug Designations for SCY-247.

Ibrexafungerp / GSK Update

GSK is committed to the relaunch of BREXAFEMME, and following its relaunch, SCYNEXIS has the potential to receive up to approximately $146 million in annual net sales milestones.

First Quarter 2026 Financial Results

Research and development expenses for the three months ended March 31, 2026, were $12.4 million compared to $5.1 million for the same period in 2025. The increase of $7.2 million, or 140%, was primarily driven by the $8.0 million IPR&D expense recognized for the acquisition of SCY-770 in the three months ended March 31, 2026 and an increase of $0.3 million in clinical expense, offset in part by a decrease of $0.7 million in preclinical expense and a decrease of $0.4 million in salary expense.

SG&A expenses for the three months ended March 31, 2026, increased to $4.6 million compared to $3.7 million for the same period in 2025. The increase of $0.9 million, or 23%, was primarily due to the $0.8 million write off of offering costs for the March 2026 private placement warrant issuance in the three months ended March 31, 2026.

Total other expenses was $4.4 million for the three months ended March 31, 2026, versus total other income of $3.2 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 March 31, 2026 and 2025, SCYNEXIS recognized a loss of $5.2 million and a gain of $2.9 million, respectively, in the fair value adjustment related to the warrant liabilities primarily due to the increase and decrease in our stock price during the respective periods.

Cash Balance

Cash, cash equivalents and investments totaled $72.4 million on March 31, 2026, compared to $56.3 million on December 31, 2025. The balance at March 31^st includes approximately $24 million of the gross proceeds of $40 million from the private placement that closed on April 1^st with certain new and existing institutional and accredited investors. The March 31^st balance plus the approximately $16 million in gross proceeds received on April 1st extends the Company's cash runway to mid-2029.
