SAN MATEO, Calif., November 12, 2025 – Talphera, Inc. (Nasdaq: TLPH), (“Talphera”), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced third quarter 2025 financial results and provided a corporate update.

“The financing closed in September, led by a strategic investment from CorMedix, combined with future conditional tranches, is expected to provide us sufficient capital through at least a Niyad PMA approval anticipated in 2026. Their investment, along with investment from existing and new financial investors, further validates the attractiveness of the Niyad market opportunity,” stated Vince Angotti CEO of Talphera. “In addition, we’re excited about the high quality and skilled execution of the NEPHRO study sites. Importantly, we have received consistent feedback from the principal investigators conveying eagerness for nafamostat to be available as their preferred alternative to current CRRT anticoagulants. The positive enrollment momentum in the NEPHRO clinical study has continued and we look forward to the recently activated sites and the remaining four planned sites to further accelerate the enrollment rate to complete the study in the first half of 2026.”

Third Quarter 2025 and Recent Highlights

●

Five target profile clinical study sites are actively enrolling patients with four additional target profile sites expected in the fourth quarter of this year.

●

In September 2025, Talphera announced the closing of the first tranche of $17 million of a two-tranche private placement financing for up to $29 million. The second closing will occur if Talphera’s stock price trades at or above $0.6875 for five consecutive days following the announcement of the achievement of the primary endpoint in the NEPHRO CRRT study. These conditions may be waived by the investors at any time. The financing was led by CorMedix, Inc. (Nasdaq: CRMD) and supported by existing investors, Nantahala Capital, Rosalind Advisors, and Rock Springs Capital, and includes several new institutional investors.

●

In September 2025, in connection with its equity investment, Talphera granted CorMedix the right to nominate one member to Talphera’s board of directors and the exclusive right of first negotiation for a potential acquisition of the Company with a 60-day exclusive negotiation period following completion and announcement of its Phase 3 study results for Niyad. In October 2025, Talphera appointed Joseph Todisco, CEO of CorMedix, to its board of directors.

●

In October 2025, certain purchasers waived the conditions of the securities purchase agreement dated March 31, 2025, to effect both the second and third closings of the private placement with respect to such purchasers only, resulting in aggregate gross proceeds to Talphera of approximately $1.6 million.

Third Quarter 2025 Financial Information

●

The cash and investments balance was $21.3 million as of September 30, 2025.

●

Combined R&D and SG&A expenses for the third quarter of 2025 totaled $3.4 million compared to $3.7 million for the third quarter of 2024. Excluding non-cash stock-based compensation expense, these amounts were $3.3 million for the third quarter of 2025, compared to $3.5 million for the third quarter of 2024. The decrease in combined R&D and SG&A expenses in the third quarter of 2025 was primarily due to reductions in personnel expense and other research and development and selling, general and administrative expenses.

●

For the third quarter of 2025, the Company recognized net loss from continuing operations of $4.4 million, as compared to net loss of $3.4 million for the third quarter of 2024, largely due to an increase in the fair value of the Company’s warrant liability partially offset by reductions in personnel expense in 2025. The divestment of DSUVIA represents a discontinued operation; accordingly, all historical operating results for the business are reflected within discontinued operations. There were no DSUVIA related expenses in the third quarter of 2025 or 2024.

●

Net loss attributable to common shareholders for the third quarter of 2025 was $4.4 million, or $0.11 per basic and diluted share, compared to a net loss of $3.4 million, or $0.13 per basic and diluted share, for the third quarter of 2024.

2025 Expense Guidance

●

Cash operating expenses, or selling, general and administrative, and research and development expenses, excluding stock-based compensation, is expected to be in the range of $14 million to $15 million in 2025, which includes the expenses related to advancing the NEPHRO CRRT registration trial. This is a reduction from the $16 million to $17 million range previously provided, with the difference expected to be realized in the first quarter of 2026.

About Niyad and Nafamostat

Nafamostat is a broad spectrum, synthetic serine protease inhibitor with anticoagulant, anti-inflammatory and potential anti-viral activities. Niyad® is a lyophilized formulation of nafamostat and is currently being studied under an IDE, as an anticoagulant for the extracorporeal circuit, and has received Breakthrough Device Designation Status from the FDA. Talphera’s registrational study of Niyad® is named the NEPHRO CRRT (Nafamostat Efficacy in Phase 3 Registrational Continuous Renal Replacement Therapy) study. An ICD-10 procedural code, XY0YX37, has been issued for the extracorporeal introduction of nafamostat. The ICD-10 code is a specific/billable code that can be used to indicate a procedure. LTX-608 is a proprietary nafamostat formulation for direct IV infusion that may be investigated and developed for the treatment of acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC), acute pancreatitis or as an anti-viral treatment, amongst other potential targets.

About the NEPHRO CRRT Study

The NEPHRO CRRT Study, which has received central IRB approval, is designed as a prospective, double-blinded trial to be conducted at up to 14 U.S. hospital intensive care units. The study will enroll and evaluate 70 adult patients undergoing renal replacement therapy, who cannot tolerate heparin or are at risk for bleeding. The primary endpoint of the study is mean post-filter activated clotting time using Niyad versus placebo over the first 24 hours. Key secondary endpoints include the mean post-filter activated clotting time over 72 hours, filter lifespan, number of filter changes over 72 hours, number of transfusions over 72 hours and dialysis efficacy (based on urea concentration) over the first 24 hours.
