CARLSBAD, Calif., May 13, 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 first quarter ended March 31, 2026, and highlighted recent corporate progress.

"Our dabogratinib '3x3' strategy continues to advance with steady progress across all three programs," said Todd Harris, Ph.D., Chief Executive Officer of TYRA. "We are taking a differentiated, data-driven approach by aligning our development strategy with the patient journey in FGFR3-driven diseases and conditions. The dosing of the first patient in SURF303 marks an important milestone, as we initiate a potentially registrational study in LG-UTUC that could support TYRA's first NDA submission. With multiple clinical data readouts expected this year, we remain focused on unlocking the full potential of selective FGFR3 inhibition with oral dabogratinib."

Doug Warner, M.D., Chief Medical Officer of TYRA, commented, "In urologic cancers, we see a significant opportunity to address what we believe is a very challenging treatment paradigm for patients that is currently dominated by procedure-based, intravesical therapies. We are developing dabogratinib as a once-daily (QD) oral therapy designed to maintain continuous pressure on the tumor and, if successful, may represent a meaningful shift in how these patients are treated."

Dr. Warner continued, "In achondroplasia, we believe our approach with oral dabogratinib may also be transformational. Recently presented data demonstrate that prenatal dosing further delayed premature fusion of synchondroses and increased the area of the foramen magnum. These data expand our perspective on the potential benefits of earlier FGFR3 inhibition as we advance BEACH301. We have now cleared the fourth dose level in our safety sentinel cohort and remain on track to report initial results in the fourth quarter of this year."

First Quarter and Recent Corporate Highlights

Dabogratinib 3x3 Strategy

In the first quarter of 2026, TYRA advanced its "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.

• 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 low grade upper tract urothelial carcinoma (LG-UTUC), a rare cancer where approximately 85% of tumors are driven by FGFR3. The Company has dosed the first patient in SURF303, with initial results expected in 2027.
• 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 intermediate risk non-muscle invasive bladder cancer (IR NMIBC). To date, there are more than 20 patients enrolled at US and international trial sites, and the Company expects to report initial three-month complete response data from both dose cohorts in August 2026.
• 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 achondroplasia (ACH). The study has enrolled the safety sentinel cohort and has successfully cleared four dose levels, with no notable safety events reported to date. The study remains on track, with initial results from the safety sentinel cohort, including 6-month average height velocity and safety data, expected in the fourth quarter of 2026.
• Presented Clinical Progress and New Preclinical Results at Key Scientific/Medical Meetings. During the first quarter of 2026 and in April, TYRA presented posters on dabogratinib for urologic cancers (SURF302 and SURF303 trials-in-progress) at the 2026 ASCO^® Genitourinary (GU) Cancers Symposium (ASCO GU), and the European Association of Urology Congress (EAU 26). TYRA will also present a trials-in-progress poster on SURF302 at the 2026 American Urologic Association (AUA) meeting. In May 2026, at the Fusion Conference on FGFR Biology, TYRA presented new preclinical results with oral dabogratinib for the treatment of ACH. When administered to pregnant mice from embryonic day 14.5 through birth then to Fgfr3Y367C/+ neonates postnatally, dabogratinib significantly increased the foramen magnum area and resulted in open synchondroses. Prenatal plus postnatal treatment further delayed premature fusion of the synchondroses compared with the postnatal alone treatment protocol (Starrett et al., 2025). Posters associated with these meetings can be accessed on the TYRA website.

Corporate

• Appointed Habib Dable to Board of Directors. In April 2026, TYRA announced the appointment of Habib Dable to its Board of Directors. Mr. Dable brings more than 30 years of leadership experience across the global biopharmaceutical industry, including deep expertise in building and scaling blockbuster franchises and guiding companies through transformative growth. Mr. Dable most recently served as President and Chief Executive Officer of Acceleron Pharma Inc., where he led the company through a period of significant growth culminating in its acquisition by Merck in 2021. Prior to Acceleron, Mr. Dable spent 22 years at Bayer AG in positions of increasing responsibility, including President of U.S. Pharmaceuticals and Executive Vice President, Global Head of Specialty Medicine. During his tenure, he provided leadership across multiple therapeutic areas, including ophthalmology, neurology, hematology, and cardiology, and oversaw the global launch of EYLEA®. Mr. Dable currently serves as an advisor at RA Capital Management, L.P.
• Strengthened Balance Sheet with ATM Utilization. In the first quarter of 2026, TYRA received $147.9M in net proceeds, after deducting fees and other expenses, following utilization of the Company's "at-the-market" offering program, issuing and selling 4,690,532 shares of common stock to a large investment management firm.

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.

First Quarter Financial Results

• Cash, Cash Equivalents and Short-Term Investments. As of March 31, 2026, TYRA had cash, cash equivalents and marketable securities of $383.5 million. The Company's current cash, cash equivalents and marketable securities are expected to allow TYRA to execute on its plans into the second half of 2028.
• Research and Development (R&D) Expenses. R&D expenses for the three months ended March 31, 2026 were $33.5 million compared to $25.0 million for the same period in 2025. The increase was primarily associated with development activities for oral dabogratinib, reflecting ongoing BEACH301 and SURF302 clinical trials and start-up costs for SURF303, partially offset by a decrease in development activities for other programs. Personnel expenses also increased, driven by headcount growth to support expanding clinical and development activities.
• General and Administrative (G&A) Expenses. G&A expenses for the three months ended March 31, 2026 were $8.5 million compared to $6.9 million for the same period in 2025. The increase was primarily driven by higher compensation and other personnel costs, driven by headcount growth.
• Net Loss. First quarter net loss was $39.3 million compared to $28.1 million for the same period in 2025.

Upcoming Anticipated Clinical Milestones:

• SURF303: initial results – 2027
• SURF302: initial three-month complete response data – August 2026
• BEACH301: initial results from safety sentinel cohort – Q4 2026

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, 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 100 patients to date across multiple clinical studies.

Oral dabogratinib is currently advancing in three Phase 2 clinical trials for LG-UTUC (SURF303), 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.
