CARLSBAD, Calif., March 2, 2026 – Tyra Biosciences, Inc. (Nasdaq: TYRA), a clinical-stage biotechnology company focused on developing next-generation precision medicines that target large opportunities in Fibroblast Growth Factor Receptor (FGFR) biology, today reported financial results for the fourth quarter and full-year ended December 31, 2025 and highlighted recent corporate progress.
“At TYRA, we are following the science,” said Todd Harris, Ph.D., CEO of TYRA. “The strength of the genetic and biological validation behind FGFR3 gives us conviction to concentrate our resources and strategy around indications where this target plays a central role. Through our “dabogratinib 3x3” strategy, we are deliberately deploying capital toward high unmet needs – low grade upper tract urothelial carcinoma (LG-UTUC), intermediate risk non-muscle invasive bladder cancer (IR NMIBC) and achondroplasia (ACH) – where selective FGFR3 inhibition has the potential to make a meaningful impact for patients, while creating significant potential long-term value.”
“Oral dabogratinib reflects years of deliberate molecular optimization to achieve highly selective FGFR3 inhibition with a profile designed to balance potency, safety and convenience,” said Doug Warner, MD, Chief Medical Officer of TYRA. “The clinical data generated to date – with more than 100 participants dosed – reinforces our confidence in its potential efficacy and tolerability and supports once-daily (QD) dosing across our targeted indications. We believe this target profile positions oral dabogratinib to deliver meaningful benefit for patients, and we look forward to expanding our clinical database this year.”
Fourth Quarter and Recent Corporate Highlights
Dabogratinib 3x3 Strategy
TYRA is focused on executing our “dabogratinib 3x3” strategy: developing the first orally available, FGFR3 selective inhibitor in 3 future potentially pivotal clinical studies to support regulatory submissions with the aim to commercialize in 3 potential blockbuster indications: LG-UTUC, IR NMIBC and ACH.
“In Q4 2025, we prioritized our portfolio to maximize potential return on invested capital,” commented Alan Fuhrman, Chief Financial Officer of TYRA. “Exiting metastatic bladder cancer allows us to focus financial and operational resources on the three core indications within our “dabogratinib 3x3” strategy that we believe offer the most compelling risk-adjusted opportunities.”
•Phase 2 LG-UTUC Study – SURF303. SURF303 is a Phase 2a/b, multicenter, open-label study designed with pivotal intent to evaluate the efficacy and safety of oral dabogratinib at two QD doses in participants with LG-UTUC, a rare cancer where approximately 85% of tumors are driven by FGFR3. Study startup is ongoing, and the first patient is anticipated to be dosed in 2026.
•Phase 2 IR NMIBC Study – SURF302. SURF302 is a Phase 2, multicenter, open-label clinical study evaluating the efficacy and safety of oral dabogratinib at two QD doses in participants with FGFR3-altered low-grade IR NMIBC. TYRA opened additional US and international trial sites in Q4 2025, and the Company expects to report initial three-month complete response data by the end of 1H 2026.
