•First study participant randomized in Phase 3 CATT1 trial evaluating cadisegliatin for the treatment of type 1 diabetes with data expected in second half of 2026

•Cadisegliatin intellectual property portfolio expanded

•Leadership team strengthened

HIGH POINT, N.C., August 12, 2025 (GLOBE NEWSWIRE) – vTv Therapeutics Inc. (Nasdaq: VTVT), a late-stage biopharmaceutical company focused on the development of cadisegliatin, a potential first-in-class oral adjunctive therapy to insulin being investigated for the treatment of type 1 diabetes (T1D), today reported financial results for the second quarter ended June 30, 2025, and provided an update on recent corporate developments.

“The randomization of the first participant in our CATT1 Phase 3 trial earlier this month reflects our continued momentum in advancing cadisegliatin,” said Paul Sekhri, Chairman, President and CEO of vTv Therapeutics. “Cadisegliatin is designed to selectively activate glucokinase in the liver, a differentiated approach that may improve glycemic control and reduce the risk of hypoglycemia when used alongside insulin. Hypoglycemic episodes remain frequent, life-disruptive, and sometimes life-threatening for people with type 1 diabetes. We believe cadisegliatin could play a meaningful role in addressing this large unmet medical need."

•First Study Participant Randomized in Cadisegliatin Phase 3 Trial. In August 2025, vTv Therapeutics announced that the first study participant was randomized in the Company’s CATT1 Phase 3 Trial evaluating cadisegliatin as an adjunctive therapy to insulin for the treatment of T1D. Topline data from the study is expected in the second half of 2026.

•Patent Allowance for Crystalline Salt Form of Cadisegliatin. In August 2025, the United States Patent and Trademark Office allowed claims for a patent application directed to compositions of matter of crystalline forms of salts and co-crystals of cadisegliatin. The patent term runs through 2041.

•Corporate Presentation at HCW@Home. In June 2025, the Company participated in a virtual fireside chat as part of the H.C. Wainwright HCW@Home series.

•Appointment of Chief Financial Officer. In May 2025, vTv Therapeutics appointed Michael Tung, MD, MBA, as Chief Financial Officer. Dr. Tung brings over 20 years of financial management, investment experience, and strategic leadership across both private and public life sciences companies.

•Cash Position: The Company’s cash position as of June 30, 2025, was $25.9 million compared to $36.7 million as of December 31, 2024.

•Research & Development (R&D) Expenses: R&D expenses were $4.1 million and $3.4 million in each of the three months ended June 30, 2025, and 2024, respectively. The increase reflects higher indirect costs primarily related to payroll expenses. This was partially offset by lower spending on cadisegliatin and other projects.

•General & Administrative (G&A) Expenses: G&A expenses were $3.6 million and $3.7 million for each of the three months ended June 30, 2025, and 2024, respectively. The decrease was primarily due to decreases in other operating costs. This was partially offset by an increase in payroll related costs.

•Other Income, Net: Other income for the three months ended June 30, 2025, was immaterial. Other income for the three months ended June 30, 2024, was $0.2 million and was driven by gains related to the change in the fair value of the outstanding warrants to purchase shares of our own stock issued to related parties.

•Net Loss: Net loss attributable to vTv shareholders for the three months ended June 30, 2025, was $6.0 million or $0.92 per basic share. Net loss attributable to vTv shareholders for the comparable period a year ago was $5.2 million or $0.81 per basic share.

Cadisegliatin (TTP399) is a novel, oral small molecule, liver-selective glucokinase activator being investigated as a potential first-in-class oral adjunctive treatment for type 1 diabetes (T1D). In non-clinical studies, cadisegliatin, acting selectively on the liver, increased the activity of glucokinase independently from insulin which supports clinical investigation of improvement in glycemic control through hepatic glucose uptake and glycogen storage.

Cadisegliatin is under investigation and the safety and efficacy have not been established. There is no guarantee that this product will receive health authority approval or become commercially available for the use being investigated.

vTv Therapeutics is a late-stage biopharmaceutical company focused on developing oral, small molecule drug candidates intended to help treat people living with diabetes and other chronic diseases. vTv's clinical pipeline is led by cadisegliatin, currently in a Phase 3 trial, a potential first-in-class oral glucokinase activator being investigated for the treatment of type 1 diabetes. vTv and its development partners are investigating multiple molecules across different indications for chronic diseases.
