"September marks an important milestone for TYRA as we prepare to share initial clinical data from SURF302 evaluating oral dabogratinib in intermediate-risk non-muscle invasive bladder cancer (IR NMIBC). Patients with IR NMIBC often endure a lifelong cycle of recurrent disease, repeated surgical procedures, catheterization, and ongoing surveillance, highlighting the need for more convenient and effective treatment options. We believe dabogratinib has the potential to redefine the treatment paradigm as the first targeted oral therapy for FGFR3-driven IR NMIBC, addressing the underlying biology of the disease while offering the convenience of an oral therapy," said Todd Harris, PhD, President and Chief Executive Officer of TYRA.
Dr. Harris continued, "Beyond SURF302, we continue to advance our broader pipeline, including progressing BEACH301 to a fifth dose level in achondroplasia, and strengthening our skeletal dysplasia leadership with the addition of Jonathan Day, whose work was instrumental in the development of vosoritide. Across our portfolio, we remain focused on realizing the full potential of oral dabogratinib for patients with FGFR3-driven conditions and diseases."
"Over the past decade, I’ve had the privilege of helping advance therapies that have transformed the treatment landscape for children with achondroplasia. I believe there is still meaningful opportunity to further improve outcomes, and TYRA’s highly selective approach to FGFR3 inhibition offers a compelling opportunity to do just that," commented Dr. Day, TYRA’s newly appointed Executive Vice President, Clinical Development. "I’m excited to join the team and help advance dabogratinib as we work to develop a differentiated oral therapy for children with achondroplasia and their families."
Second Quarter and Recent Corporate Highlights
Dabogratinib 3×3 Strategy
In the second quarter of 2026, TYRA continued to advance its "dabogratinib 3×3" 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 (60 mg and 80 mg) in participants with low-grade upper tract urothelial carcinoma (LG-UTUC), a rare cancer where approximately 85% of tumors are driven by FGFR3. Initial results from this study are 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 (50 mg and 60 mg) in participants with FGFR3-altered low-grade IR NMIBC. The Company will host a conference call and webcast in September 2026 to report initial results from the SURF302 study, including safety results from more than 40 patients and efficacy from more than 20 patients in the aggregate at both QD dose levels.
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 successfully cleared four dose levels, with no notable safety events reported to date. Given the favorable safety profile seen to date across dose levels 1 through 4 in BEACH301, the Data Safety Monitoring Committee authorized the opening of a fifth dose level to evaluate 0.625 mg/kg in the safety sentinel cohort. Initial results from the safety sentinel cohort, including 6-month annualized height velocity and safety data for dose levels 1-5, which will include an aggregate of approximately 25 children, are expected to be reported at the end of Q1 2027.
Corporate
Appointed Jonathan Day as EVP, Clinical Development for Skeletal Dysplasia Conditions. In June 2026, TYRA appointed Jonathan Day, MBBS, PhD, FFPM, FESC, as Executive Vice President, Clinical Development, where he will lead the Company’s development program and clinical strategy for oral dabogratinib in skeletal dysplasia conditions. Dr. Day is a physician-scientist and pharmaceutical executive with extensive experience leading late-stage clinical development programs in rare diseases. At BioMarin Pharmaceutical, he served as Head of R&D for the Skeletal Conditions Business Unit (previously Group Vice President, Late-Stage Clinical Development), where he led the global clinical development strategy for the company’s skeletal dysplasia portfolio, including vosoritide (Voxzogo) for achondroplasia. Before joining BioMarin, Dr. Day was Vice President and Global Medical Lead for Acute Cardiovascular Care at The Medicines Company, and earlier served as Medical Director for the UK & Ireland at AstraZeneca. Prior to industry, he trained in cardiothoracic surgery and completed a PhD at Imperial College London focused on thrombin inhibition and cardiovascular medicine. He is also a Fellow of the European Society of Cardiology and the Faculty of Pharmaceutical Medicine.
Amended ATM Sales Agreement. In August 2026, TYRA entered into an amended sales agreement with TD Securities (USA) LLC, under which TYRA may sell up to the amount registered on an effective registration statement under which the offering is made, subject to other limitations. Pursuant to the amended sales agreement, as of the date hereof, TYRA may sell an additional $250.0 million of shares of its common stock from time to time in "at-the-market" offerings.
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.
Second Quarter Financial Results
Cash, Cash Equivalents and Marketable Securities. As of June 30, 2026, TYRA had cash, cash equivalents and marketable securities of $353.9 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 June 30, 2026 were $39.2 million compared to $24.3 million for the same period in 2025. The increase was primarily associated with development activities for oral dabogratinib, supporting the ongoing SURF303, SURF302 and BEACH301 clinical trials, partially offset by a decrease in development activities for other programs. There were also increases in personnel expenses, driven by 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 June 30, 2026 were $9.8 million compared to $7.1 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. Second quarter net loss was $45.6 million compared to $28.1 million for the same period in 2025.
Upcoming Anticipated Clinical Milestones:
SURF303: initial results – 2027
SURF302: initial results from both dose cohorts – September 2026
BEACH301: initial results from dose levels 1-5 of safety sentinel cohort – end of Q1 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, 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), 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.
