\n -Dabogratinib is the only oral FGFR3-selective inhibitor in clinical development for achondroplasia-<\/i>\n <\/p>\n

\n -Initial results from safety sentinel cohort expected in 2H 2026-<\/i>\n <\/p>\n

\n
\n CARLSBAD, Calif.<\/span>
\n <\/span>, Aug. 21, 2025<\/span><\/span> \/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, announced today that the first child has been dosed in BEACH301, a Phase 2 clinical study evaluating the safety and efficacy of dabogratinib in children with achondroplasia, the most common form of dwarfism.\u00a0 Dabogratinib is a potential first-in-class, once-daily oral FGFR3 selective inhibitor that was discovered using the TYRA’s in-house SN\u00c5P platform.<\/p>\n

“Achondroplasia is caused by an alteration in FGFR3, and we believe that precisely targeting the root cause of this condition is the key to transforming care,” said Todd Harris<\/span>, CEO of TYRA. “Dabogratinib is the only oral, FGFR3-selective inhibitor in clinical development for achondroplasia, reflecting our commitment to bring forward therapies that are both innovative and accessible for children and their families. Dosing the first child in BEACH301 is more than a milestone for our company \u2014 it’s a step toward a future where children with achondroplasia can live healthier, fuller lives.”<\/p>\n

It is estimated that 1 in 15,000 to 40,000 children are born with achondroplasia, and approximately 250,000 individuals are affected worldwide. People living with achondroplasia may experience health complications including foramen magnum and spinal stenosis, sleep apnea and disproportionate short stature. An\u00a0FGFR3<\/i>\u00a0G380R gain of function mutation accounts for approximately 99% of achondroplasia cases.<\/p>\n

“Dosing the first child in BEACH301 is a pivotal moment for TYRA as we work to bring next-generation, transformational therapies to areas of profound unmet need,” said Doug Warner<\/span>, M.D., Chief Medical Officer of TYRA. “Dabogratinib is designed as an easy-to-take oral option, offering an improved administration approach for children and their families. We are grateful to the achondroplasia community \u2014 including healthcare providers, families, caregivers, and advocacy organizations \u2014 for partnering with us to shape this program, and we look forward to learning how dabogratinib may impact growth and lead to quality-of-life improvements that matter most to children with achondroplasia.”<\/p>\n

\n Chandler Crews<\/span>, Founder, Advocate, The Chandler Project, commented, “Families living with achondroplasia need new treatment options, and our community is encouraged to see TYRA stepping into this space with such dedication. TYRA’s approach with dabogratinib is different\u2014it’s designed to specifically target FGFR3 \u2014and that has generated real excitement among families and advocates. The launch of the BEACH301 trial represents important progress, and we look forward to following TYRA’s work as we collectively push toward a future with more choices and better outcomes for people around the world.”\u00a0<\/p>\n

Dr. Klane K. White<\/span>, MD, MSc, Chair of Pediatric Orthopedics, Children’s Hospital Colorado, “Enrolling and dosing the first child in the BEACH301 trial represents a new landmark in advancing care for children with achondroplasia. As a physician, I see firsthand the advantage of more targeted options, and dabogratinib’s FGFR3\u2013specific approach represents an exciting evolution in how we think about treatment. It’s deeply rewarding to be part of a study that has the potential to reshape the future for these children and their families.”<\/p>\n

\n About BEACH301<\/b>\n <\/p>\n

BEACH301 is a Phase 2, multicenter, open-label, dose-escalation\/dose-expansion study evaluating dabogratinib in children ages 3 to 10 with achondroplasia who have open growth plates. The study will enroll children who are treatment-na\u00efve (Cohort 1) and those who have received prior growth-accelerating therapy (Cohort 2) at multiple sites across the globe. Each of these cohorts is expected to enroll up to 10 participants per dose level (0.125, 0.25, 0.375, 0.50 mg\/kg) for up to 12 months.\u00a0 The study is also enrolling a safety sentinel cohort of up to 3 participants per dose level in children ages 5 to 10.<\/p>\n

The primary objectives of this study will be to assess safety and tolerability in children with achondroplasia and evaluate change from baseline in annualized growth velocity to determine the dose(s) for further development. Secondary objectives will include evaluating change from baseline in height z-score, proportionality and pharmacokinetics.

\n About Achondroplasia<\/b>\n <\/p>\n

Achondroplasia is the most common form of dwarfism.\u00a0It is estimated that 1 in 15,000 to 40,000 children are born with achondroplasia, and approximately 250,000 individuals are affected worldwide. People living with achondroplasia may experience health complications including foramen magnum and spinal stenosis, sleep apnea and disproportionate short stature. An\u00a0FGFR3<\/i>\u00a0G380R gain of function mutation accounts for approximately 99% of achondroplasia cases. Dabogratinib is a first-in-class oral FGFR3 selective inhibitor whose design may have a meaningful impact on achondroplasia and other skeletal dysplasia.<\/p>\n

\n About Dabogratinib (formerly TYRA-300)\u00a0<\/b>\n <\/p>\n

Dabogratinib is TYRA’s lead precision medicine candidate stemming from its in-house SN\u00c5P platform. Dabogratinib is an investigational, oral, FGFR3-selective inhibitor currently in development for the treatment of cancer and skeletal dysplasia that has demonstrated interim clinical proof-of-concept results in metastatic urothelial cancer (mUC). The current planned clinical development for dabogratinib includes Phase 2 clinical trials for intermediate risk (IR) non-muscle invasive bladder cancer (NMIBC) (SURF302) and pediatric achondroplasia (BEACH301), and potentially future mUC studies.\u00a0The U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) and Rare Pediatric Disease (RPD) Designation to dabogratinib for the treatment of achondroplasia.<\/p>\n
