CARLSBAD, Calif., Nov. 7, 2023 /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, 2023 and highlighted recent corporate progress.

"From the start, TYRA has focused on developing precision therapies that target large opportunities that exist in FGFR biology, and we continue to follow the data.   We continue to advance TYRA-300, our oral FGFR3-selective inhibitor, as we dose expand and escalate in our SURF301 oncology study and strengthen our preclinical data package in achondroplasia," said Todd Harris, CEO of TYRA. "Before the end of the year, we expect to update our guidance on the timing and design of our planned Phase 2 study in achondroplasia and the dosing of our first patient with TYRA-200."

Third Quarter 2023 and Recent Corporate Highlights

TYRA-300

• SURF301 Phase 1/2 Study for Oncology Continued to Advance. SURF301 (Study in Untreated and Resistant FGFR3+ Advanced Solid Tumors) (NCT05544552) is a multi-center, open label study designed to determine the optimal and maximum tolerated doses (MTD) and the recommended Phase 2 dose of TYRA-300, as well as to evaluate the preliminary antitumor activity of TYRA-300. Enrollment is ongoing in Part A and Part B and dose escalation is ongoing in Part B in Phase 1 of the study at multiple clinical sites in the U.S., Europe, and Australia. In this study, multiple doses and schedules of TYRA-300 will be evaluated to inform dosing decisions in future metastatic urothelial carcinoma (mUC), non-muscle invasive bladder cancer (NMIBC) and achondroplasia studies.
  
  
• Presented Positive Preclinical Data for Achondroplasia at ASBMR and ASHG Meetings. In October and early November 2023, TYRA presented additional preclinical results on TYRA-300 in achondroplasia at the American Society for Bone and Mineral Research (ASBMR) and the American Society of Human Genetics (ASHG) 2023 annual meetings, respectively. In preclinical mice models of achondroplasia conducted at The Imagine Institute in Paris, TYRA-300 increased bone growth, improved the shape of the skull, improved the shape of the foramen magnum, restored the architecture of the growth plate, and increased chondrocyte proliferation and differentiation.
  
  
• Granted Orphan Drug Designation for Achondroplasia from FDA. In July 2023, TYRA-300 was granted Orphan Drug Designation (ODD) for the treatment of achondroplasia from the U.S. Food and Drug Administration (FDA).

TYRA-200

• Phase 1 Study on Track to be Initiated by YE '23. TYRA continued to advance activities to support the initiation of the planned Phase 1 clinical study of TYRA-200, an FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations and resistance mutations. The trial will be focused on intrahepatic cholangiocarcinoma resistant to prior FGFR inhibitors. TYRA remains on track to dose the first patient in this trial before year-end 2023.

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.

Third Quarter 2023 Financial Results

• Third quarter 2023 net loss was $21.2 million compared to $12.5 million for the same period in 2022.
• Third quarter 2023 research and development expenses were $19.3 million compared to $10.9 million for the same period in 2022.
• Third quarter 2023 general and administrative expenses were $4.7 million compared to $2.7 million for the same period in 2022.
• As of September 30, 2023, TYRA had cash and cash equivalents of $215.7 million that are expected to support TYRA's important clinical and operational milestones over at least the next two years.

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 recommended Phase 2 dose (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 for the initiation of a Phase 2 clinical study in pediatric achondroplasia in 2024.  In July 2023, TYRA-300 was granted Orphan Drug Designation for the treatment of achondroplasia from the FDA.

The forward-looking statements are based on our current beliefs and expectations and include, but are not limited to: the potential to develop next-generation precision medicines and the potential safety and therapeutic benefits of TYRA-300 and other product candidates; the sufficiency of our cash position to support clinical and operational milestones; expected cash runway; the expected timing and phase of clinical development of TYRA-300 and TYRA-200, including timing of a submission of an IND for TYRA-300 in pediatric achondroplasia and patient dosing for TYRA-200; expected timing regarding updated guidance on the timing and design of our planned Phase 2 study in achondroplasia and dosing of our first patient with TYRA-200; and the potential for SNÅP to develop therapies in targeted oncology and genetically defined conditions. Actual results may differ from those set forth in this press release due to the risks and uncertainties inherent in our business, including, without limitation: we are early in our development efforts, have only recently begun testing TYRA-300 for oncology in clinical trials and the approach we are taking to discover and develop drugs based on our SNÅP platform is novel and unproven and it may never lead to product candidates that are successful in clinical development or approved products of commercial value; potential delays in the commencement, enrollment, and completion of preclinical studies and clinical trials; results from preclinical studies or early clinical trials not necessarily being predictive of future results; our dependence on third parties in connection with manufacturing, research and preclinical testing; we may expend our limited resources to pursue a particular product candidate and/or indication and fail to capitalize on product candidates or indications with greater development or commercial potential; acceptance by the FDA of INDs or of similar regulatory submissions by comparable foreign regulatory authorities for the conduct of clinical trials of TYRA-300 in pediatric achondroplasia; an accelerated development or approval pathway may not be available for TYRA-300 or other product candidates and any such pathway may not lead to a faster development process; unexpected adverse side effects or inadequate efficacy of our product candidates that may limit their development, regulatory approval, and/or commercialization; the potential for our programs and prospects to be negatively impacted by developments relating to our competitors, including the results of studies or regulatory determinations relating to our competitors; we may not realize the benefits associated with ODD, including that orphan drug exclusivity may not effectively protect a product from competition and that such exclusivity may not be maintained; regulatory developments in the United States and foreign countries; we may use our capital resources sooner than we expect; unstable market and economic conditions and adverse developments with respect to financial institutions and associated liquidity risk may adversely affect our business and financial condition and the broader economy and biotechnology industry; and other risks described in our prior filings with the Securities and Exchange Commission (SEC), including under the heading "Risk Factors" in our annual report on Form 10-K and any subsequent filings with the SEC.
