Tyra Biosciences, Inc. (TYRA)

Overview

We are a clinical-stage biotechnology company focused on developing next-generation precision medicines for large opportunities in targeted oncology and genetically defined conditions, harnessing the power of Fibroblast Growth Factor Receptor (FGFR) biology.

Our in-house precision medicine platform, SNÅP, enables rapid and precise drug design through iterative molecular SNÅPshots that help us design and predict which product candidates may demonstrate the highest potency, selectivity and tolerability in the clinic. Through this approach, we have built a wholly-owned pipeline of oral small molecule product candidates focused on targets that have previously been considered difficult-to-drug.

Our FGFR3 Programs—oral dabogratinib for Urothelial Cancers and Skeletal Dysplasia

Alterations in the protein receptor FGFR3 are a validated driver in multiple indications with large market opportunities: urothelial cancers and skeletal dysplasia conditions. In urothelial cancer, uncontrolled activation of FGFR3 on the cell surface stimulates cellular proliferation. In skeletal dysplasia conditions, increased activity of FGFR3 expressed in growth plate chondrocytes (cartilage cells) results in excessive limitation of long bone growth.

17

Our lead program, oral dabogratinib, was designed to be more selective for FGFR3 over FGFR1, FGFR2, and FGFR4 to minimize off-target side effects, providing potential clinical advantages over less selective first-generation compounds and potentially addressing key unmet needs across both urothelial cancers and skeletal dysplasia conditions. To date, oral dabogratinib has been administered to over 200 individuals across multiple clinical and healthy volunteer studies.

We are currently advancing oral dabogratinib in three Phase 2 trials for three outsized market indications: SURF303, evaluating the treatment of low-grade upper tract urothelial carcinoma (LG-UTUC); SURF302, evaluating the treatment of intermediate risk non-muscle invasive bladder cancer (IR NMIBC); and BEACH301, evaluating the treatment of achondroplasia (ACH) in children. If we are successful with these Phase 2 studies, we expect to advance oral dabogratinib toward three potential registrational trials in LG-UTUC, IR NMIBC and ACH. We are calling this approach our “dabogratinib 3x3” strategy.

SURF303 for LG-UTUC: This open-label Phase 2a/b clinical trial was designed as a potential registrational trial to evaluate the efficacy and safety of oral dabogratinib at doses of 60 mg and 80 mg once daily (QD) in participants with FGFR3-altered LG-UTUC, where approximately 85% of tumors are driven by FGFR3. The Company is currently dosing and enrolling patients in SURF303, with initial results expected in 2027.

SURF302 for IR NMIBC: This open-label Phase 2 clinical trial is evaluating the efficacy and safety of oral dabogratinib at 50 mg and 60 mg QD in participants with FGFR3-altered low-grade IR NMIBC, where approximately 70% of tumors are driven by FGFR3. The Company expects to report initial results from both dose cohorts during a conference call and webcast in September 2026, including safety results from more than 40 patients and efficacy from more than 20 patients in the aggregate at both QD dose levels.

BEACH301 for ACH: This study is an open-label, Phase 2 dose-escalation/dose-expansion trial evaluating oral dabogratinib at multiple doses (0.125, 0.25, 0.375, 0.50, and 0.625 mg/kg), in children ages 3 to 10 with ACH with open growth plates, where approximately 99% of cases are driven by FGFR3. The study has enrolled the safety sentinel cohort, consisting of at least 3 participants per dose level in children ages 5 to 10, and is enrolling a natural history run-in for cohorts 1 and 2 with children ages 3 to 10. No notable safety events have been reported to date. Initial results from the safety sentinel cohort, including 6-month annualized height velocity and safety data from all five dose levels, are expected to be reported at the end of the first quarter of 2027, which will include an aggregate of approximately 25 children.

Our Other Programs

TYRA-430 was designed to be biased for FGFR4 and FGFR3 over the FGFR1 and FGFR2 isoforms specifically to address the FGF19 signaling pathway, while also potentially limiting side effects due to inhibition of FGFR1 and FGFR2, as well as to address acquired resistance mutations that have limited the efficacy of previous FGFR4-specific inhibitors. TYRA-430 is currently being evaluated in SURF431, a global, Phase 1, multicenter, open-label trial, with a focus on achieving clinical proof-of-concept in a cohort of patients with FGF19+ hepatocellular carcinoma (HCC).

TYRA-200 is an FGFR1/2/3 inhibitor designed to be active against nearly all of the clinically identified acquired resistant mutations that arise during treatment with pan-FGFR inhibitors, which we believe is necessary to address the problem of disease progression due to polyclonal resistance. TYRA-200 is currently being evaluated in SURF201, a global, Phase 1, multicenter, open-label trial, with a focus on achieving clinical proof-of-concept in a cohort of FGFR2-driven intrahepatic cholangiocarcinoma (ICC) resistant to previous FGFR inhibitors.

Financial Overview

Since the commencement of our operations in 2018, we have devoted substantially all of our resources to organizing and staffing the company, business planning, raising capital, developing our proprietary SNÅP platform, undertaking research and development activities for our development programs, establishing our intellectual property portfolio, and providing general and administrative support for our operations. We have not generated any revenue to date and have funded our operations primarily from our initial public offering (IPO), private placements of our convertible preferred stock, the issuance of common stock and pre-funded common stock warrants through a private placement and the issuance of common stock through an at-the-market offering program. Our net losses for the six months ended June 30, 2026 and 2025 were $84.9 million and $56.2 million, respectively. As of June 30, 2026, we had an accumulated deficit of $456.1 million. As of June 30, 2026, we had cash, cash equivalents and marketable securities of $353.9 million.

18

We have incurred significant operating losses since inception. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical development activities, other research and development activities and capital expenditures. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future if and as we continue to develop and conduct clinical trials for our product candidates, continue our research and development activities for future product candidates, expand our clinical and regulatory capabilities, add operational and management information systems and hire additional personnel, expand and protect our intellectual property, establish marketing, sales, distribution and other commercialization capabilities if we obtain approval for any of our product candidates and incur additional costs associated with operating as a public company.

Based on our current operating plan, we believe that our cash, cash equivalents and marketable securities as of June 30, 2026 will be sufficient to fund our operating expenses and capital expenditures into the second half of 2028. We have never generated any revenue and do not expect to generate any revenue from product sales unless and until we successfully complete the development of and obtain regulatory approval for our product candidates, which will not be for several years, if ever. In addition, if we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, until we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our cash needs through equity offerings, debt financings or other capital sources, including potential collaborations, licenses and other similar arrangements. However, we may not be able to raise additional funds or enter into such other arrangements when needed or on favorable terms, or at all. If we are unable to raise additional capital or enter into such arrangements when needed, we could be forced to delay, limit, reduce or terminate our research and development programs or future commercialization efforts, or grant rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.

Research and Development Expenses

To date, our research and development expenses consist primarily of external and internal costs related to the development of our SNÅP platform and our product candidates and development programs. Our research and development expenses primarily include:

•
external costs, including:

o
expenses incurred in connection with conducting clinical trials, including investigator grants and site payments for time and pass-through expenses and expenses incurred under agreements with contract research organizations (CROs), central laboratories and other vendors and service providers engaged to conduct our trials;

o
expenses incurred in connection with the discovery and preclinical development of our product candidates, including under agreements with third parties, such as consultants and CROs;

o
costs associated with consultants for chemistry, manufacturing and controls (CMC) development, and other services;

o
the cost of manufacturing compounds for use in our preclinical studies, including under agreements with third parties, such as consultants and third-party manufacturers; and

o
costs related to compliance with drug development regulatory requirements; and

•
internal costs, including:

o
employee-related expenses, including salaries, related benefits, recruiting costs, travel and share-based compensation expenses for employees engaged in research and development functions;

o
the costs of laboratory supplies and acquiring, developing and manufacturing preclinical study materials; and

o
facilities, depreciation and other indirect expenses, which include allocated expenses for rent and maintenance of facilities, and supplies.

19

We expense research and development expenses in the periods in which they are incurred. External expenses are recognized based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers or our estimate of the level of service that has been performed at each reporting date. We track external expenses on a development program and other program-specific basis. However, we do not track internal costs, such as personnel-related expenses, stock-based compensation expense, facility-related costs and supplies and certain external consultant costs on a program-specific basis because these costs are deployed across multiple programs under development.

Research and development activities are central to our business model. There are numerous factors associated with the successful development of any of our product candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. In addition, future regulatory factors beyond our control may impact our clinical development programs. Product candidates in later stages of development generally have higher development costs than those in earlier stages of development. As a result, we expect that our research and development expenses will increase substantially over the next several years as we advance our product candidates into later phases of clinical trials o

To date, oral dabogratinib has been administered to over 100 participants across multiple clinical studies.

We demonstrated initial clinical proof-of-concept results with oral dabogratinib in the SURF301 study, a Phase 1 proof-of-concept study in metastatic urothelial carcinoma (mUC). Oral dabogratinib demonstrated encouraging anti-tumor activity and was generally well-tolerated, with infrequent FGFR2- and FGFR1-associated toxicities. Response, safety, pharmacokinetics (PK) / pharmacodynamics (PD) and circulating tumor DNA (ctDNA) data from this study were leveraged to select doses that have the potential to achieve our target product profile for efficacy and safety in our Phase 2 trials and beyond.

We are currently advancing oral dabogratinib in three Phase 2 trials for three outsized market indications: SURF303, evaluating the treatment of low-grade upper tract urothelial carcinoma (LG-UTUC); SURF302, evaluating the treatment of intermediate risk non-muscle invasive bladder cancer (IR NMIBC); and BEACH301, evaluating the treatment of achondroplasia (ACH) in children.

Study startup is ongoing and the first patient in this study is anticipated to be dosed in 2026.

SURF302 for IR NMIBC: This open-label Phase 2 clinical trial is evaluating the efficacy and safety of oral dabogratinib at 50 mg and 60 mg QD in participants with FGFR3-altered low-grade IR NMIBC, where approximately 70% of tumors are driven by FGFR3. We anticipate reporting initial three-month CR data from approximately 10-20 patients per cohort from this study by the end of the first half of 2026.

BEACH301 for ACH: This study is an open-label, Phase 2 dose-escalation/dose-expansion trial evaluating oral dabogratinib at lower doses (0.125, 0.25, 0.375, 0.50 mg/kg), as compared to the oncology studies, in children ages 3 to 10 with ACH with open growth plates, where approximately 99% of cases are driven by FGFR3. The study is enrolling a safety sentinel cohort of 3 or more participants per dose level in children ages 5 to 10, and a natural history run-in for cohorts 1 and 2 with children ages 3 to 10. Initial results from the safety sentinel cohort, including 6-month average height velocity (AHV) results and interim safety, are on-track and expected to be reported in the second half of 2026.
