Current report

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. We have initially leveraged our SNÅP approach to develop TYRA-300, TYRA-200 and TYRA-430: three clinical-stage, novel small molecules designed to overcome the toxicity and resistance liabilities of first generation pan-FGFR inhibitors.

Current report

Our FGFR3 Programs - TYRA-300 for Bladder Cancer and Skeletal Conditions

Current report

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

Current report

Our lead program, TYRA-300, 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 bladder cancer and skeletal conditions.

Current report

TYRA-300 is to be evaluated in three Phase 2 studies: SURF301, for the treatment of metastatic urothelial carcinoma (mUC); SURF302, for the treatment of non-muscle invasive bladder cancer (NMIBC); and BEACH301, for the treatment of pediatric achondroplasia (ACH).

Current report

SURF301 for mUC: This ongoing study is an international, multi-center, open label Phase 1/2 clinical trial that was designed to determine the optimal and maximum tolerated doses (MTD), and the recommended Phase 2 dose (RP2D) of TYRA-300, as well as to evaluate the preliminary antitumor activity of TYRA-300. In late October 2024, we reported interim data that in patients with FGFR3+ mUC who received doses ≥ 90 mg once daily (QD), 6 out of 11 (54.5%) patients achieved a confirmed partial response. Preliminary data, as of the August 15, 2024 data cutoff, suggested TYRA-300 was generally well-tolerated, with infrequent FGFR2- and FGFR1-associated toxicities. Dose optimization is ongoing in this study.

Current report

SURF302 for NMIBC: This study is an open-label Phase 2 clinical trial evaluating the efficacy and safety of TYRA-300 at lower doses (50 and 60mg QD) in participants with FGFR3-altered low-grade, intermediate risk (IR) NMIBC. We expect to dose the first patient in this study in the second quarter of 2025.

Current report

BEACH301 for ACH: This study is an open-label, Phase 2 dose-escalation/dose-expansion trial evaluating TYRA-300 at lower doses (0.125, 0.25, 0.375, 0.50 mg/kg) in children ages 3 to 10 with ACH with open growth plates. Prior to initiation of the first two cohorts, the study will enroll a safety sentinel cohort of up to 3 treatment-naïve participants per dose level in children ages 5 to 10. We expect to dose the first child in this study in the second quarter of 2025.

Current report

Our FGFR2 Program - TYRA-200 for Intrahepatic Cholangiocarcinoma

Current report

FGFR2 is a protein receptor present on the cell surface that promotes cellular proliferation and transformation upon binding of fibroblast growth factor. Activating gene alterations of FGFR2 have been implicated in the tumorigenesis of multiple solid tumor types, with pan-FGFR inhibitors approved for intrahepatic cholangiocarcinoma (ICC).

Current report

FGF19 is a post-prandial enterohepatic hormone that signals through FGFR4 and its associated co-receptor Klotho Beta (KLB) to exert its normal cellular functions. In certain cancers, FGF19 is aberrantly expressed due to focal chromosomal amplifications or epigenetic mechanisms, promoting tumor cells to become dependent on the FGFR4/KLB/FGF19 oncogenic axis. Recent insights into FGF/FGFR signaling in HCC have indicated an important bypass mechanism in FGFR3, which shares the Klotho Beta coreceptor.

Current report

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 will be initially studied in SURF431, a global Phase 1 multicenter, open-label, study in advanced HCC and other solid tumors with activating FGF/FGFR pathway aberrations (SURF431). We expect to dose the first patient in this study in the second quarter of 2025.

Current report

We track most external development costs by development program. We do not allocate internal costs, such as personnel-related expenses, stock-based compensation expense, facility, supplies and certain external consultant costs, to individual development programs.

Current report

Research and development expenses were $80.1 million and $62.5 million for the years ended December 31, 2024 and 2023, respectively. The overall increase of $17.6 million was driven by:

Current report

$7.3 million increase in clinical costs driven by progression of SURF301 and SURF201 clinical trials and start-up activities related to BEACH301, SURF302 and SURF431 study launches;

Current report

$1.7 million decrease in preclinical costs due to a decrease in early drug discovery and toxicology costs as various programs moved into clinical development;

Current report

$0.3 million decrease in CMC costs for most programs in the clinical stage, except for TYRA-300 ACHand certain preclinical programs;

Current report

$10.4 million increase in compensation and other personnel expenses, including an increase in stock-based compensation costs of $6.0 million, driven by headcount growth; and

Current report

$1.9 million increase in facilities and other operating costs due to our continuing expansion efforts.

Current report

General and administrative expenses were $24.1 million and $17.4 million for the years ended December 31, 2024 and 2023, respectively. The increase of $6.7 million was driven by:

Current report

$4.9 million increase in compensation and other personnel expenses, including an increase in stock-based compensation costs of $3.3 million, driven by headcount growth;

Current report

$1.4 million increase in professional services, legal and other public company costs; and

Current report

Net cash provided by financing activities for the year ended December 31, 2024 was $202.1 million, consisting primarily of proceeds from the issuance of common stock and pre-funded warrants from the 2024 Private Placement of $200 million, offset by issuance costs of $0.4 million, and proceeds from the issuance of common stock under benefit plans of $2.5 million.

Current report

Our material cash requirements consist of expected operating expenses to conduct our clinical trials and other research and development activities, facility and operating lease obligations.

Current report

In addition, we enter into agreements and purchase orders in the normal course of business with vendors for the provision of goods and services. These agreements may include certain provisions for termination, with notice, which typically consist of payments for services provided or expenses incurred through the date of cancellation. We believe that our non-cancelable obligations under these agreements are not material.

Previous report

In oncology, the widespread availability of approved targeted treatments, such as kinase inhibitors, has transformed the cancer treatment landscape. Despite the therapeutic benefit that targeted oncology treatments have created for some patients, the response rate and duration of efficacy is often limited by acquired drug resistance, off-target toxicities and other shortcomings of existing therapies. We are using our proprietary SNÅP platform in order to generate novel product candidates that are specifically designed to limit off-target toxicities and address acquired drug resistance to provide next-generation treatment options.

Previous report

Our lead product candidate, TYRA-300, is an investigational, oral, FGFR3-selective inhibitor currently being evaluated in an international, multi-center, open label Phase 1 clinical study, SURF301 (Study in Untreated and Resistant FGFR3+ Advanced Solid Tumors). SURF301 (NCT05544552) was designed to determine the optimal and maximum tolerated doses (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 locally advanced or metastatic urothelial carcinoma (mUC) and other advanced solid tumors with FGFR3 gene alterations. As of March 2024, the Part A Phase 1 portion of SURF301 has completed dose escalation without determining an MTD, and the current expansion cohorts in Part B are evaluating potentially therapeutic once daily and twice daily doses. We expect to submit initial results from the SURF301 Phase 1 portion for presentation at a scientific congress in the second half of 2024.

Previous report

Beyond oncology, FGFR3 is implicated in many genetically-defined conditions, such as achondroplasia (ACH) and other skeletal dysplasias, due to its role in regulating bone and cartilage formation. In March 2023, we announced we were expanding development of TYRA-300 into ACH based on positive preclinical results demonstrated in a study performed in collaboration with the Imagine Institute in Paris, France. Data from the study showed that TYRA-300 increased body length in mice by 17.9% compared to the vehicle (p<0.0001) and increased the length of the femur (+22.6%), tibia (+33.0%) and L4-L6 (+23.5%) in mice (p<0.0001) (with n=8 for TYRA-300, after excluding two mice from the dataset when molecular analysis showed chimeric incorporation of mutation, and n=10 for vehicle, after excluding one vehicle mouse from the dataset when molecular analysis showed chimeric incorporation of mutation). Achondroplasia, the most common form of dwarfism, is a skeletal dysplasia in which growth plate cartilage is affected, resulting in decreased growth of the long bones, vertebral bodies and skull base. These growth differences can result in health complications such as foramen magnum and spinal stenosis, hydrocephalus, genu varum (bowed legs), and sleep apnea. A specific DNA mutation in FGFR3 causes an estimated 99% of ACH.

Previous report

We believe that the design of TYRA-300 may have a meaningful impact on ACH and potentially other skeletal dysplasias. We are conducting additional IND-enabling studies and plan to submit an Investigational New Drug (IND) application 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 ACH. We expect that the primary objective of this study will be to assess safety and tolerability in children with ACH and determine the dose(s) for further development. We expect that secondary objectives will include evaluating change in growth velocity, growth proportionality and PK. We are 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. Our 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 ACH who have received and did not tolerate or respond to a prior growth accelerating therapy. In July 2023 and January 2024, the FDA granted Orphan Drug Designation (ODD) and Rare Pediatric Disease (RPD) Designation to TYRA-300, respectively, for the treatment of ACH.

Previous report

General and administrative expenses were $17.4 million and $15.9 million for the years ended December 31, 2023 and 2022, respectively. The increase of $1.5 million was primarily due to an increase in professional services costs of $1.0 million, an increase in personnel costs of $0.9 million, and an increase in facilities and other operating costs of $0.1 million. The increase was partially offset by a decrease in stock-based compensation costs of $0.5 million.

Previous report

On February 6, 2024, we completed a private placement of 9,286,023 shares of our common stock and pre-funded warrants to purchase an aggregate of 6,087,230 shares of our common stock in lieu of shares of common stock for gross proceeds of approximately $200 million, before deducting offering expenses. We will file a registration statement on Form S-3 registering the resale of the shares of common stock and shares of common stock issuable upon the exercise of pre-funded warrants issued in the private placement.

Previous report

We are not obligated to sell, and the Agent is not obligated to buy or sell, any shares of common stock under the Sales Agreement. No assurance can be given that we will sell any shares of common stock under the Sales Agreement, or, if we do, as to the price or amount of shares of common stock that we may sell or the dates when such sales will take place. As of December 31, 2023, we have not sold any shares under the Sales Agreement.

Previous report

In addition, we enter into agreements in the normal course of business with certain vendors for the provision of goods and services, which includes manufacturing services with CMOs and development services with CROs. These agreements may include certain provisions for purchase obligations and termination obligations that could require payments for the cancellation of committed purchase obligations or for early termination of the agreements. The amount of the cancellation or termination payments vary and are based on the timing of the cancellation or termination and the specific terms of the agreement. These obligations and commitments are not separately presented.

Previous wording

Our second oncology product candidate, TYRA-200, is an investigational, oral, FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations, as well as clinically important molecular brake and gatekeeper resistance mutations. TYRA-200 is currently being evaluated in a multi-center, open label Phase 1 clinical study, SURF201 (Study in Previo Usly treated and Resistant FGFR2+ Cholangiocarcinoma and Other Advanced Solid Tumors) (NCT06160752) that is designed to evaluate the safety, tolerability, and PK of TYRA-200 and determine the optimal dose for further development and the MTD and RP2D, as well as evaluate preliminary antitumor activity.

Current wording

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 a multi-center, open label Phase 1 clinical study, SURF201 that is designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of TYRA-200, determine the optimal dose for further development and the MTD and RP2D, and evaluate preliminary antitumor activity, with a focus on achieving proof-of-concept in a cohort of FGFR2-driven ICC resistant to previous FGFR inhibitors.

As of December 31, 2024, we had cash, cash equivalents, and marketable securities of $341.4 million.

Previous wording

Based on our current operating plan, we believe that our cash, cash equivalents and marketable securities as of December 31, 2023, together with gross proceeds of approximately $200 million from the 2024 PIPE, will be sufficient to fund our operating expenses and capital expenditures through at least 2026. We have never generated any revenue and do not expect to generate any revenues from product sales unless and until we successfully complete 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 such time as 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.

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events, and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions.

Previous wording

The Company has entered into various research and development contracts with clinical research organizations, clinical manufacturing organizations, clinical sites and other vendors and consultants. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and payments made in advance of or after performance are reflected in the accompanying balance sheets as prepaid expenses or accrued liabilities, respectively. The Company records accruals for estimated costs incurred for ongoing research and development activities. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the services, including the phase or completion of events, invoices received and contracted costs. The Company holds discussions with applicable personnel and outside service providers as to the progress of clinical trials, or the services completed. Significant judgments and estimates may be made in determining the prepaid or accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. Nonrefundable advance payments for goods and services, including fees for process development, are deferred and recognized as expense in the period that the related goods are consumed, or services are performed.
