(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, 2025, and highlighted recent corporate progress. "In 2025, we are focused on clinical execution across our portfolio of next-generation precision therapies for oncology and skeletal dysplasia. We continued to advance TYRA-300 for ACH and intermediate risk non-muscle invasive bladder cancer and will begin dosing in BEACH301 and SURF302 in the second quarter," stated Todd Harris, CEO of TYRA. "In addition, our SURF431 study is now underway, and we dosed the first HCC patient with TYRA-430, our oral FGFR4/3-biased inhibitor for FGF19+/FGFR4-driven cancers." First Quarter 2025 and Recent Corporate Highlights TYRA-300 Advanced Clinical Evaluation of TYRA-300 and Published Preclinical Research. TYRA continued to progress TYRA-300, an oral, investigational FGFR3-selective inhibitor, for the treatment of intermediate risk non-muscle invasive bladder cancer (IR NMIBC), pediatric achondroplasia (ACH), and metastatic urothelial cancer (mUC). Advanced Phase 2 ACH Study - BEACH301 - Open for Enrollment. The study is a Phase 2, multicenter, open-label, dose-escalation/dose-expansion study evaluating TYRA-300 in children ages 3 to 10 with achondroplasia with open growth plates. The study will enroll children who are treatment-naïve (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. The study is now enrolling a safety sentinel cohort of up to 3 treatment-naïve participants per dose level in children ages 5 to 10. Advanced Phase 2 NMIBC Study Activities – SURF302. SURF302 is an open-label Phase 2 clinical study evaluating the efficacy and safety of TYRA-300 in participants with FGFR3-altered low-grade, IR NMIBC. The study will enroll up to 90 participants at multiple sites primarily in the United States. Participants will be randomized initially to treatment with TYRA-300 at 50 mg once-daily (QD) (Cohort 1) or treatment with TYRA-300 at 60 mg QD (Cohort 2). Following a review of efficacy and safety, an additional dosing cohort may be evaluated. The primary endpoint is complete response (CR) rate at three months. Secondary endpoints include time to recurrence, the median duration of response, recurrence free survival (RFS), progression free survival (PFS), safety and tolerability. Advanced Phase 1/2 mUC Study – SURF301. TYRA-300 is currently being evaluated in Part B of SURF301 (NCT05544552) at potentially therapeutic QD doses in preparation for potential future Phase 2 studies. Preclinical Results with TYRA-300 Published in JCI Insight. In April 2025, preclinical results with TYRA-300 were published in JCI Insight 2025 in a manuscript titled "TYRA-300, an FGFR3 selective inhibitor, promotes bone growth in two FGFR3-driven models of chondrodysplasia." TYRA-300 was evaluated in three genetic contexts: wild-type mice, the Fgfr3Y367C/+ mouse model of ACH, and the Fgfr3N534K/+ mouse model of HCH. In each model, TYRA-300 treatment increased naso-anal length, tibia and femur length. In the two FGFR3-altered models, TYRA 300-induced growth partially restored the disproportionality of long bones. Histologic analysis of the growth plate in Fgfr3Y367C/+ mice revealed that TYRA-300 mechanistically increased both proliferation and differentiation of chondrocytes. Importantly, TYRA-300 also significantly improved the size and shape of the skull and foramen magnum in Fgfr3Y367C/+ mice. These studies demonstrate that TYRA-300 led to a significant increase in bone growth in two independent FGFR3-driven preclinical models, as well as in wild-type mice. TYRA-200 Advanced Phase 1 SURF201 Study. TYRA-200 is an FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations and resistance mutations. SURF201 (Study in PrevioUsly Treated and Resistant FGFR2+ Cholangiocarcinoma and Other Advanced Solid Tumors) (NCT06160752) is a multi-center, open label study designed to evaluate the safety, tolerability, and pharmacokinetics of TYRA-200 and determine the optimal and maximum tolerated dose and recommended Phase 2 dose, as well as evaluate the preliminary antitumor activity of TYRA-200. The SURF201 study continues to enroll and dose adults with unresectable locally advanced/metastatic intrahepatic cholangiocarcinoma and other advanced solid tumors with activating FGFR2 gene alterations. TYRA-430 Initiated Patient Dosing in Phase 1 Study – SURF431. TYRA-430 is an oral, investigational FGFR4/3-biased inhibitor for FGF19+/FGFR4-driven cancers. Patient dosing has commenced in SURF431, a Phase 1, multicenter, open-label, first-in-human study of TYRA-430 in advanced hepatocellular carcinoma (HCC) and other solid tumors with activating FGF/FGFR pathway aberrations (NCT06915753). SURF431 is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of TYRA-430 and determine the maximum tolerated dose and recommended Phase 2 dose, as well as evaluate the preliminary antitumor activity of TYRA-430. We believe TYRA-430 has the potential to address a significant unmet need in HCC, where there are no approved biomarker-driven, targeted therapies. 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 2025 Financial Results Cash, Cash Equivalents and Short-Term Investments. As of March 31, 2025, TYRA had cash, cash equivalents, and marketable securities of $318.9 million. The Company's current cash, cash equivalents and marketable securities are expected to allow TYRA to execute on its plans through at least 2027. Research and Development (R&D) Expenses. R&D expenses for the three months ended March 31, 2025 were $25.0 million compared to $17.2 million for the same period in 2024.
