Tvardi Therapeutics Announces Third Quarter 2025 Results and Provides Business Update

On track for topline data from Phase 2 trial of TTI-101 in hepatocellular carcinoma (HCC) in H1 2026

Results from healthy volunteer study of its next-generation STAT3 inhibitor, TTI-109, expected in H1 2026

Cash runway sufficient to fund operations into Q4 2026

Tvardi Therapeutics, Inc. ("Tvardi") (NASDAQ:TVRD), a clinical-stage biopharmaceutical company focused on the development of novel, oral, small molecule therapies targeting STAT3 to treat fibrosis-driven diseases, today announced its financial and operating results for the third quarter ended September 30, 2025, and provided a business update.

Third Quarter 2025 and Recent Highlights:

• Continued to progress its Phase 2 study of TTI-101 in HCC, with topline data anticipated in the first half of 2026.
• Announced that the IND for its next-generation STAT3 inhibitor, TTI-109, is in effect and that a healthy volunteer study has been initiated, results of which are anticipated in the first half of 2026.
• In October, the company reported preliminary data from the Phase 2 REVERT IPF trial and concluded that the study did not meet its goals. Tvardi is conducting additional analyses to further understand these results and inform next steps.

Imran Alibhai, Ph.D., Chief Executive Officer of Tvardi, stated, "While we continue to analyze the results from our REVERT IPF clinical trial to determine the most appropriate path forward, we remain confident in the potential of STAT3 inhibition to address fibrosis-driven diseases. We believe our lead program, TTI-101, has demonstrated encouraging clinical activity in oncology and continues to hold promise across a range of indications where STAT3 is a key driver.

"To that end, we eagerly await data from our ongoing Phase 2 REVERT Liver Cancer trial in the first half of next year. Interim results from this study have already shown clinically meaningful activity of TTI-101 both as monotherapy and in combination with established anti-cancer agents across treatment lines.

"At the same time, we are also advancing our next-generation STAT3 inhibitor, TTI-109, through a healthy volunteer study. TTI-109 is designed to rapidly convert to TTI-101 and lessen the exposure of the active drug to the intestinal lining. We believe TTI-109 strengthens our STAT3-targeted approach by providing a more efficient delivery mechanism for TTI-101 that has the potential to improve tolerability.

"With a balance sheet extending into the fourth quarter of next year, we remain focused on fully realizing the therapeutic potential of STAT3 inhibition across fibrotic diseases."

Upcoming Milestones:

• Preliminary topline data from the company's ongoing REVERT Liver Cancer Phase 1b/2 clinical trial of TTI-101 anticipated in the first half of 2026
• Preliminary topline data from a healthy volunteer study of its next-generation STAT3 inhibitor, TTI-109, also anticipated in the first half of 2026

Third Quarter 2025 Financial Results

Research and development expenses for the three months ended September 30, 2025, were $3.6 million as compared to $4.8 million for the comparable period in 2024. The decrease of $1.2 million was primarily driven by lower costs associated with TTI-101, including decreases of $1.4 million and $1.0 million related to Tvardi's HCC and IPF trials, respectively. The decrease in Tvardi's HCC trial expense was primarily attributable to the changes in patient enrollments and estimated study costs, while the decrease in Tvardi's IPF trial expense was attributable to the trial being completed in the second quarter of 2025. These declines were partly offset by an increase of $2.0 million related to the ongoing healthy volunteer study of TTI-109, which began in the third quarter of 2025, as well as related CMC costs.

General and administrative expenses were $2.3 million for the three months ended September 30, 2025, compared to $0.9 million for the three months ended September 30, 2024. The increase of approximately $1.5 million was primarily driven by increases in professional fees of $0.7 million, attributable to higher legal fees and ongoing accounting and audit fees. The remaining increase was attributable to higher personnel costs, insurance costs and rent and other related costs.

Net loss for the three months ended September 30, 2025 was $5.5 million, roughly flat with the comparable period in 2024.

Basic and diluted net loss per share attributable to common shareholders for the three months ended September 30, 2025 were a net loss of $0.59 on a basic and diluted basis, compared to a net loss of $2.14 on a basic and diluted basis for the comparable period in 2024.

Cash, cash equivalents and short-term investments as of September 30, 2025, were $36.5 million, as compared to $31.6 million as of December 31, 2024. Tvardi anticipates that its current cash runway is sufficient to fund operations, as currently planned, into the fourth quarter of 2026.
