Tyra Biosciences Reports Third Quarter 2026 Financial Results and Recent Highlights

Reported initial Phase 2 SURF302 results for oral dabogratinib in FGFR3-altered low-grade IR NMIBC patients

Completed $400 million financing, providing additional capital to advance dabogratinib's 3x3 strategy

Cash runway through 2030 with cash, cash equivalents and marketable securities of $700.5 million as of September 30, 2026

CARLSBAD, Calif., Nov. 10, 2026 /PRNewswire/ -- 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 third quarter ended September 30, 2026, and highlighted recent corporate progress.

"2026 has been a defining year for TYRA. With the initial results from SURF302 in the ablative setting, we believe dabogratinib has the potential to be the first oral FGFR3-selective inhibitor in intermediate-risk non-muscle invasive bladder cancer (IR NMIBC), reinforcing our conviction in the potential of precision FGFR3 inhibition to fundamentally change the treatment paradigm for patients," said Todd Harris, PhD, President and Chief Executive Officer of TYRA. "For too long, patients have faced a cycle of repeated procedures and surveillance, often simply waiting for their cancer to recur. We believe dabogratinib has the potential to break this cycle by offering a differentiated, first-in-class oral product candidate that could transform how patients and physicians manage this chronic, recurrent disease."

Dr. Harris continued, "With a strengthened balance sheet following our $400 million financing, TYRA is entering its next phase of growth from a position of strength. We now have the financial resources to advance our dabogratinib 3x3 strategy through late-stage clinical development. As we prepare for regulatory engagement and planned Phase 3 development, we believe the opportunity for a highly selective, oral FGFR3 inhibitor has never been clearer. We look forward to building on our recent momentum as we work to establish dabogratinib as a potentially transformative therapy for patients with FGFR3-driven diseases."

Third Quarter and Recent Corporate Highlights

Dabogratinib 3x3 Strategy

During the third quarter of 2026, TYRA achieved a significant milestone in its dabogratinib 3x3 strategy with initial clinical results in IR NMIBC. The strategy is focused on advancing oral dabogratinib, an investigational FGFR3-selective inhibitor, across three potentially pivotal development programs in low-grade upper tract urothelial carcinoma (LG-UTUC), low-grade IR NMIBC and achondroplasia (ACH).

• Phase 2 IR NMIBC Study – SURF302. In September 2026, TYRA reported initial results from SURF302 (data cutoff as of August 31, 2026), its Phase 2 ablative study evaluating oral dabogratinib in patients with FGFR3-altered low-grade IR NMIBC.
  • At 60 mg QD, oral dabogratinib demonstrated a 79% overall response rate (ORR) and 64% best overall response (BOR) complete response (CR) rate among participants with single and multiple marker lesions (n=14).
  • Among participants with a single marker lesion (n=8), 60 mg QD demonstrated a 100% ORR and 75% BOR CR rate, supporting the planned Phase 3 adjuvant strategy.
  • Initial safety and tolerability results were favorable across both dose cohorts (n=44), with no clinically significant hyperphosphatemia, nail toxicity or ocular toxicity observed. There were no Grade 3 treatment-related adverse events at 60 mg QD.
  • TYRA has completed enrollment in the 60 mg QD cohort and is enrolling a 70 mg QD cohort to further explore oral dabogratinib's potential in the ablative setting.
  • TYRA is advancing preparations for registrational development, including planned engagement with health authorities regarding design of a Phase 3 adjuvant study. Initiation of the study is expected in 2027, subject to regulatory feedback.
• 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 (60 mg and 80 mg) in participants with LG-UTUC. In September 2026, TYRA reported that the first participant treated in SURF303 achieved a complete response (CR) at the 3-month assessment with 60 mg QD, with no observed treatment-emergent adverse events as of the August 31, 2026 data cutoff. TYRA continues to advance enrollment and expects to report additional clinical results in 2027.
• Phase 2 ACH Study – BEACH301. BEACH301 is a Phase 2, multicenter, open-label, dose-escalation/dose-expansion study evaluating oral dabogratinib in children ages 3 to 10 with ACH. The study has advanced through five dose levels in the safety sentinel cohort. Given the favorable safety data seen to date across dose levels 1 through 5, the Data Safety Monitoring Committee authorized the opening of a sixth dose level to evaluate 0.875 mg/kg in the safety sentinel cohort. Initial results from the safety sentinel cohort, including six-month annualized height velocity and safety data, representing approximately 25 children in aggregate, are expected in 2027.

Corporate

• Completed $400 Million Financing. In September 2026, TYRA completed an underwritten public offering of common stock and pre-funded warrants with gross proceeds of approximately $400 million, before underwriting discounts, commissions and offering expenses. The financing was led by RA Capital Management, with participation from new and existing institutional investors. Together with existing cash resources, the financing is expected to support execution of the Company's dabogratinib 3x3 strategy, as well as ongoing research and development activities, through 2030.

SNÅP Platform and Pipeline

• TYRA continued to advance its in-house precision medicine discovery engine, SNÅP, used to develop therapies in targeted oncology and genetically defined conditions.

Third Quarter Financial Results

• Cash, Cash Equivalents and Marketable Securities. As of September 30, 2026, TYRA had cash, cash equivalents and marketable securities of $700.5 million. Following its September 2026 financing, the Company expects its current financial resources to fund planned operations through 2030.
• Research and Development (R&D) Expenses. R&D expenses for the three months ended September 30, 2026 were $43.1 million compared to $25.5 million for the same period in 2025. The increase was primarily driven by dabogratinib development activities supporting the ongoing SURF303, SURF302 and BEACH301 clinical trials. The remaining increase was driven by personnel expenses, primarily due to headcount growth to support expanding clinical and development activities, and expenses for facilities and other costs.
• General and Administrative (G&A) Expenses. G&A expenses for the three months ended September 30, 2026 were $11.7 million compared to $7.5 million for the same period in 2025. The increase primarily related to higher compensation and other personnel costs, driven by headcount growth.
• Net Loss. Third quarter net loss was $51.1 million compared to $29.9 million for the same period in 2025.

Upcoming Anticipated Clinical Milestones:

• IR NMIBC: Phase 3 adjuvant study initiation; additional Phase 2 ablative study results – 2027
• LG-UTUC: Initial Phase 2 results – 2027
• ACH: Initial Phase 2 results from safety sentinel cohort – 2027

About Dabogratinib (formerly TYRA-300)

Dabogratinib is TYRA's lead precision medicine candidate stemming from its in-house SNÅP platform. Dabogratinib is an investigational, oral, FGFR3-selective inhibitor currently in Phase 2 development for the treatment of urologic cancers and skeletal dysplasias, specifically LG-UTUC, low-grade IR NMIBC and ACH. We believe dabogratinib was the first orally available, FGFR3-selective inhibitor to enter clinical development, and it has been studied in more than 200 individuals to date across multiple clinical and healthy volunteer studies.

Oral dabogratinib is currently advancing in three Phase 2 clinical trials for LG-UTUC (SURF303), low-grade IR NMIBC (SURF302), and ACH (BEACH301). The FDA has granted Orphan Drug Designation and Rare Pediatric Disease Designation to oral dabogratinib for the treatment of achondroplasia.
