CARLSBAD, Calif., Nov. 7, 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 September 30, 2024, and highlighted recent corporate progress.

"These are exciting times at TYRA.  We are very pleased with the interim data reported with TYRA-300 at ENA 2024. TYRA-300 demonstrated impressive anti-tumor activity at dose levels ≥ 90 mg once daily and was generally well-tolerated with infrequent FGFR1 and FGFR2 toxicities that limit the tolerability of pan-FGFR inhibitors. These data provide clinical support that an FGFR3 inhibitor designed to be highly selective can deliver meaningful clinical benefit to heavily pretreated patients with cancer," said Todd Harris, CEO of TYRA.  "These results allow us to expand into larger studies for multiple bladder cancer indications, including metastatic urothelial cancer (mUC) and non-muscle invasive bladder cancer (NMIBC), while aiming to achieve best-in-class annualized growth velocity in achondroplasia (ACH). We look forward to initiating the Phase 2 study for ACH in the first quarter of 2025 and submitting an IND for NMIBC by the end of this year."

Third Quarter 2024 and Recent Corporate Highlights

TYRA-300

• Reported Interim Clinical Proof-of-Concept Results from SURF301 Phase 1/2 Study (NCT05544552) in Patients with mUC.  In October 2024, TYRA reported interim data with TYRA-300 during a late-breaking oral presentation at the 36^th EORTC-NCI-AACR (ENA) Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain. The results included encouraging preliminary anti-tumor activity observed in a heavily pre-treated population: at ≥ 90 mg once daily (QD), 6 out of 11 (54.5%) patients with FGFR3+ mUC achieved a confirmed partial response (PR), with 100% disease control rate and sustained duration of activity; positive safety results were reported across all once-daily (QD) doses, with infrequent FGFR2/FGFR1-associated toxicities. The interim results warrant continued development of TYRA-300 for mUC and the Company is prioritizing QD dosing in SURF301 and future oncology studies. TYRA-300 is currently being evaluated in Part B of SURF301 at potentially therapeutic QD doses in preparation for potential future Phase 2 studies in NMIBC and mUC.
  
  
• Phase 2 IND Submission for NMIBC on Track for Year-End 2024. TYRA plans to expand the clinical development of TYRA-300 into NMIBC to address the unmet needs in this cancer population with an efficacious, orally available therapy. TYRA remains on track to submit an Investigational New Drug (IND) application for a Phase 2 study of TYRA-300 in NMIBC before year-end 2024.
  
  
• IND Clearance Received for Phase 2 Achondroplasia (ACH) Study (BEACH301). In October 2024, TYRA announced that the U.S. Food and Drug Administration (FDA) cleared its IND application for TYRA-300 allowing the company to proceed with a Phase 2 clinical trial of TYRA-300 for children with achondroplasia (BEACH301). The study will be 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.  Prior to initiation of Cohorts 1 and 2, the study will enroll a safety sentinel cohort of up to 3 treatment-naïve participants per dose level in children ages 5 to 10.  TYRA expects to dose the first child with achondroplasia in BEACH301 in Q1 2025.
  
  
• Peer-Reviewed Manuscript Published in Journal of Medicinal Chemistry. In September 2024, a manuscript titled "Discovery of TYRA-300: First oral selective FGFR3 inhibitor for the treatment of urothelial cancers and achondroplasia" was published in the Journal of Medicinal Chemistry (J. Chem) by the American Chemical Society. The published data provides preclinical evidence that TYRA-300 is a potentially best-in-class, novel precision small molecule designed to be selective for FGFR3 while sparing FGFR1 and 2 isoform toxicities and on-target gatekeeper resistant mutations.  These results support the advancement of TYRA-300 in the ongoing SURF301 Phase 1/2 clinical study and the expansion into achondroplasia and hypochondroplasia. 

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 investigational, 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.

TYRA-430

• Continued Phase 1 Planning Following IND Clearance. TYRA announced that the FDA cleared its IND to proceed with a Phase 1 clinical study of TYRA-430, an investigational, FGFR4/3-biased inhibitor for FGF19⁺/FGFR4-driven cancers.  The Phase 1 study will be a 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 (SURF431).  We believe TYRA-430 has the potential to address a significant unmet need in HCC, where there are no approved biomarker-driven, targeted therapies. 

Corporate

• Appointed Doug Warner, MD, as Chief Medical Officer (CMO).  In September 2024, TYRA announced the appointment of Dr. Warner as CMO, who brings over twenty years of proven clinical development leadership to TYRA having successfully led global development and secured approvals for medicines across oncology and skeletal disease.  Prior to TYRA, Dr. Warner held roles of increasing responsibility over 18 years at Amgen where he oversaw clinical development for programs across oncology and bone diseases. This included being an Executive Director and Group Product Area Lead, where Dr. Warner led a team responsible for the development of a portfolio of medicines ranging from those in Phase 1 to those with approved indications, including Vectibix®, XGEVA®, and Prolia®. Most recently, Dr. Warner was Chief Medical Officer for eFFECTOR Therapeutics where he was responsible for overseeing eFFECTOR's clinical pipeline, including its KICKSTART Phase 2b trial of tomivosertib in non-small cell lung cancer, and its Phase 1/2 study of zotatifin in solid tumors. Dr. Warner is co-author of numerous peer-reviewed articles including those in The Lancet, The Lancet Oncology, and The Journal of Clinical Oncology. He received his B.A. from the University of Pennsylvania, his M.D. from the Duke University School of Medicine, and his M.B.A. from the UCLA Anderson School of Management.
