CARLSBAD, Calif., March 19, 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 fourth quarter and full year ended December 31, 2023 and highlighted recent corporate progress.

"2023 was an outstanding year for TYRA and we are pleased to have positive momentum at the start of 2024," said Todd Harris, CEO of TYRA.  "We have strong conviction in our pipeline and believe our lead program TYRA-300 has the potential to become a best-in-class agent for multiple high-value indications.  TYRA-300 remains our top priority and we are focused on submitting our Phase 2 IND for achondroplasia, while optimizing dose in SURF301 in preparation for Phase 2 studies in NMIBC and metastatic urothelial carcinoma."

"TYRA is in our strongest financial position to date, with a pro-forma cash position of over $400 million following our PIPE last month.  Our ability to retain and attract high quality investors reflects the excitement around our pipeline to deliver value for both shareholders and patient communities," added Alan Fuhrman, Chief Financial Officer of TYRA.  "Our current cash, cash equivalents and marketable securities on hand allow us to execute on our plans through at least 2026."

Fourth Quarter 2023 and Recent Corporate Highlights

• Closed a $200M Private Placement Financing. In February 2024, TYRA entered into a securities purchase agreement with new and existing institutional and accredited investors to sell securities in a private placement financing (the PIPE) for gross proceeds of approximately $200 million. The financing was led by RA Capital Management, with participation by new and existing institutional investors, including Boxer Capital, BVF Partners, Nextech Invest Ltd (on behalf of one or more funds managed by it), OrbiMed, 5AM Ventures, a large investment management firm and a life-sciences focused institutional investor.

TYRA-300

• Received FDA Rare Pediatric Disease Designation for the Treatment of Achondroplasia. In January 2024, TYRA-300 was granted Rare Pediatric Disease (RPD) Designation for the treatment of achondroplasia from the U.S. Food and Drug Administration (FDA). TYRA-300 has also received Orphan Drug Designation (ODD) for the treatment of achondroplasia from the FDA.
  
  
• 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) continues to advance. The study is a multi-center, open label study designed to determine the optimal and maximum tolerated dose (MTD) 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 multiple doses and schedules of TYRA-300 in future studies in metastatic urothelial carcinoma (mUC), non-muscle invasive bladder cancer (NMIBC) and achondroplasia. As of March 2024, the Part A Phase 1 portion of SURF301 has completed dose escalation, and the current expansion cohorts in Part B are evaluating potentially therapeutic once daily and twice daily doses. TYRA expects to submit initial results from its SURF301 Phase 1 portion for presentation at a scientific congress in the second half of 2024.
  
  
• Phase 2 Achondroplasia (ACH) Study On Track. TYRA is planning to initiate 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's current expectation is that the study will initially evaluate treatment naïve children ages 5-12 to determine optimal dose ranges and will also include a separate cohort and analysis of children ages 5-12 with achondroplasia who have received and did not tolerate or respond to a prior growth accelerating therapy. TYRA plans to submit an Investigational New Drug (IND) application to the FDA in the second half of 2024 for the initiation of the Phase 2 study.

TYRA-200

• Phase 1 SURF201 Study Initiated. 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 PK of TYRA-200 and determine the optimal and 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.

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 including FGF19⁺/FGFR4-driven cancers and others.

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 ODD and RPD Designation to TYRA-300, respectively, for the treatment of achondroplasia.
