CARLSBAD, Calif., May 9, 2024 /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 quarter ended March 31, 2024, and highlighted recent corporate progress.

"During the first quarter of 2024, we focused on execution across our pipeline including delivering on our near-term milestones for TYRA-300 in both achondroplasia and oncology," said Todd Harris, CEO of TYRA. "In oncology, the TYRA-300 clinical profile continues to mature in SURF301, and our clinical team is focused on Part B dose expansion to evaluate multiple dosing regimens of TYRA-300. We believe this work will support future Phase 2 studies in NMIBC and metastatic urothelial carcinoma, where we see tremendous opportunity for an oral FGFR3-selective inhibitor. In achondroplasia, we remain on track to submit our IND in the second half of 2024 to support our planned Phase 2 study."

First Quarter 2024 and Recent Corporate Highlights

• Strengthened Board with New Appointments. On May 7, 2024, TYRA announced changes to its Board of Directors with the appointments of Susan Moran, M.D., M.S.C.E. and S. Michael Rothenberg, M.D., Ph.D. as independent directors, and the resignation of Isan Chen, M.D.

TYRA-300

• SURF301 Phase 1/2 Study for Oncology Continued to Advance. The SURF301 Phase 1 study for oncology (Study in Untreated and Resistant FGFR3+ Advanced Solid Tumors) (NCT05544552) continued to advance. The study is a multi-center, open label study designed to determine the optimal and the recommended Phase 2 dose (RP2D) of TYRA-300, as well as to evaluate the preliminary antitumor activity of TYRA-300. TYRA expects that the Phase 1 portion of SURF301 will provide data to inform the appropriate dosing schedule of TYRA-300 in future studies in metastatic urothelial carcinoma (mUC) and non-muscle invasive bladder cancer (NMIBC). Part A of SURF301 is complete and the expansion cohorts in Part B are evaluating potentially therapeutic once daily and twice daily doses, in preparation for future Phase 2 studies in NMIBC and mUC. TYRA remains on track to report initial results from its SURF301 Phase 1 portion at a scientific congress in the second half of 2024.
  
  
• Phase 2 Achondroplasia (ACH) Study Planning Continued to Advance. TYRA remains on track to submit an Investigational New Drug application (IND) to the FDA in the second half of 2024 for the initiation of a Phase 2 clinical trial testing multiple doses of TYRA-300 to support children with achondroplasia. TYRA expects that the primary objective of this study will be to assess safety and tolerability in children with achondroplasia and determine the dose(s) for further development. TYRA also expects that secondary objectives will include evaluating change in growth velocity, growth proportionality and pharmacokinetics (PK). TYRA is also planning exploratory assessments of clinical outcomes and quality of life measures, and an evaluation of biomarkers to determine dose-response relationships to TYRA-300.

TYRA-200

• Phase 1 SURF201 Study Continued to Advance. The SURF201 (Study in PrevioUsly treated and Resistant FGFR2+ Cholangiocarcinoma and Other Advanced Solid Tumors) (NCT06160752) continued to advance. The study is a multi-center, open label study designed to evaluate the safety, tolerability, and PK of TYRA-200 and determine the optimal and maximum tolerated dose (MTD) and RP2D, as well as evaluate the preliminary antitumor activity of TYRA-200.

TYRA-200 is an FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations and resistance mutations. The SURF201 study is currently enrolling and dosing adults with unresectable locally advanced/metastatic intrahepatic cholangiocarcinoma and other advanced solid tumors with activating FGFR2 gene alterations.

Corporate

• Closed a $200M Private Placement Financing. In February 2024, TYRA completed a private placement financing, pursuant to which it sold shares of its common stock and pre-funded warrants to purchase its common stock to new and existing institutional and accredited investors for gross proceeds of approximately $200 million.

SNÅP Platform and Pipeline

• TYRA continued to advance its in-house precision medicine discovery engine, SNÅP, to develop therapies in targeted oncology and genetically defined conditions.
• TYRA nominated its third candidate for clinical development, TYRA-430, an FGFR4/3 selective inhibitor for FGF19⁺/FGFR4-driven cancers. TYRA is focused on completing IND-enabling studies for this program.

Fourth Quarter and Full Year 2023 Financial Results

• First quarter 2024 net loss was $18.2 million compared to $11.9 million for the same period in 2023.
• First quarter 2024 research and development expenses were $17.2 million compared to $10.4 million for the same period in 2023.
• First quarter 2024 general and administrative expenses were $5.1 million compared to $3.9 million for the same period in 2023.
• As of March 31, 2024, TYRA had cash, cash equivalents, and marketable securities of $382.5 million. The company's current cash, cash equivalents and marketable securities on hand allow TYRA to execute on its plans through at least 2026.

About TYRA-300

TYRA-300 is the Company's lead precision medicine program stemming from its in-house SNÅP platform. TYRA-300 is an investigational, oral, FGFR3-selective inhibitor currently in development for the treatment of cancer and skeletal dysplasias, including achondroplasia. In oncology, TYRA-300 is being evaluated in a multi-center, open label Phase 1/2 clinical study, SURF301 (Study in Untreated and Resistant FGFR3+ Advanced Solid Tumors). SURF301 (NCT05544552) was designed to determine the optimal and MTD and the RP2D of TYRA-300, as well as to evaluate the preliminary antitumor activity of TYRA-300. SURF301 is currently enrolling adults with advanced urothelial carcinoma and other solid tumors with FGFR3 gene alterations. In skeletal dysplasias, TYRA-300 has demonstrated positive preclinical results, and the Company expects to submit an IND in the second half of 2024 for the initiation of a Phase 2 clinical study in pediatric achondroplasia. In July 2023 and January 2024, the FDA granted Orphan Drug Designation (ODD) and Rare Pediatric Designation (RPD) to TYRA-300, respectively, for the treatment of achondroplasia.
