"2024 was another year filled with significant progress and milestone achievements that position Tempest for a successful future," said Stephen Brady, president and chief executive officer of Tempest. "Despite challenging capital markets, our lean team excelled, reporting key OS data from the ongoing randomized Phase 2 trial of amezalpat in first-line hepatocellular carcinoma. As previously announced, we have secured broad regulatory agreement with both the FDA and EMA on the Phase 3 plan and received both Orphan Drug and Fast Track designations from the FDA. We also advanced our second clinical program, TPST-1495, with a Phase 2 clinical trial for the treatment of patients with FAP, with data expected in 2026. Our focus remains on execution with excellence while securing the resources necessary to drive these promising drug candidates forward."

2024 & Recent Accomplishments

Amezalpat (TPST-1120) (clinical PPARα antagonist):

Granted both Orphan Drug and Fast Track designations by the U.S. Food and Drug Administration (FDA) for amezalpat for the treatment of patients with HCC.
Received a "Study May Proceed" letter from the FDA to evaluate amezalpat in combination with atezolizumab (TECENTRIQ) and bevacizumab (Avastin), the current standard of care for unresectable or metastatic HCC, in a pivotal Phase 3 trial for the first-line treatment of unresectable or metastatic HCC.
Announced an agreement with F. Hoffmann-La Roche Ltd. (Roche) to advance the evaluation of amezalpat in combination with atezolizumab and bevacizumab into a pivotal Phase 3 trial for the first-line treatment of unresectable or metastatic HCC.
Announced positive feedback from the end-of-Phase 2 meeting with the FDA for amezalpat in combination with atezolizumab and bevacizumab to treat first-line unresectable or metastatic HCC.
Reported new positive survival data from the ongoing global randomized Phase 1b/2 clinical study demonstrating that amezalpat delivered a six-month improvement in median overall survival (OS) when combined with atezolizumab and bevacizumab in comparison to atezolizumab and bevacizumab alone, the standard of care, in the first-line treatment of patients with unresectable or metastatic HCC.
Published positive data from Phase 1 trial of amezalpat in patients with advanced solid tumors in the Journal of Cancer Research Communications. Data showed that amezalpat demonstrated clinical activity, including tumor shrinkage, even in PD-1 inhibitor-refractory and immune-compromised cancers. These data complement the positive Phase 1b/2 data reported in October 2023 and June 2024 from a global randomized study of amezalpat in combination with atezolizumab and bevacizumab in first-line patients with advanced HCC.
Reported new preclinical data at the 2024 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting demonstrating that amezalpat reduces kidney cancer growth as a monotherapy, while also showing increased inhibition when combined with frontline chemotherapy and immunotherapy. These data further support the clinical benefit observed in the amezalpat Phase 1 data presented in an oral presentation at ASCO (Free ASCO Whitepaper) 2022.
TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist)
Received a "Study May Proceed" letter from the FDA to evaluate TPST-1495 in a Phase 2 Trial for the treatment of FAP.
Corporate:
Expanded leadership team to strengthen global clinical expertise with the appointments of Troy M. Wagner as Vice President of Quality Assurance and Sheldon Mullins as Vice President of Regulatory Affairs.
Potential Future Milestones

Amezalpat (TPST-1120) (clinical PPARα antagonist)
Plan to advance amezalpat into a registrational study in first-line liver cancer patients, subject to obtaining additional resources.
TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist)
Plan to advance TPST-1495 into a Phase 2 study in patients with FAP under the auspices of the Cancer Prevention Clinical Trials Network and funded by the National Cancer Institute (NCI) Division of Cancer Prevention in 2025, with data expected in 2026.
Financial Results

Year End 2024

Tempest ended the year with $30.3 million in cash and cash equivalents, compared to $39.2 million on December 31, 2023. The decrease was primarily due to cash used in operating activities, offset by proceeds from the issuance of common stock of $28.6 million from the at-the-market offering program.
Net loss and net loss per share for the year were $41.8 million and $1.50, respectively, compared to $29.5 million and $1.91, respectively, for the same period in 2023.
Research and development expenses for the year were $28.5 million compared to $17.5 million for the same period in 2023. The $11.0 million increase was primarily due to an increase in costs incurred from engaging contract research and manufacturing organizations in preparation for our pivotal Phase 3 trial of amezalpat for the treatment of first-line HCC.
General and administrative expenses for the year were $13.6 million compared to $11.7 million for the same period in 2023. The $1.9 million increase was primarily due to an increase in stock-based compensation expense due to increased headcount as well as an increase in expenses related to legal and consulting services.

"2024 was a momentous year for TYRA and the patient communities we serve, highlighted by the positive interim results from our SURF301 study, which demonstrated a combination of high anti-tumor activity with favorable tolerability results in very sick, heavily pre-treated cancer patients. Importantly, the oncology doses tested in SURF301 are significantly higher than those to be tested in BEACH301, giving us confidence as we advance TYRA-300 in ACH," said Todd Harris, CEO of TYRA. "Our conviction in TYRA-300 has never been stronger and we are working diligently to advance this potential best-in-class agent for multiple high-value indications in oncology and skeletal dysplasia into three Phase 2 studies in NMIBC, ACH and mUC."

Fourth Quarter and Full Year 2024 and Recent Corporate Highlights

TYRA-300

•
Advanced Clinical Evaluation of TYRA-300 into Three Phase 2 Studies. During 2024, TYRA progressed TYRA-300, an oral, investigational FGFR3-selective inhibitor, for the treatment of IR NMIBC, mUC and ACH, and achieved the following milestones:
o
Cleared Phase 2 NMIBC IND with US FDA – SURF302. TYRA expanded the clinical development of TYRA-300 into NMIBC to address the unmet needs in this cancer population for an efficacious, orally available therapy. SURF302 is an open-label Phase 2 clinical study evaluating the efficacy and safety of TYRA-300 in participants with FGFR3-altered low-grade, IR NMIBC. The study will enroll up to 90 participants at multiple sites primarily in the United States. Participants will be randomized initially to treatment with TYRA-300 at 50 mg once-daily (QD) (Cohort 1) or treatment with TYRA-300 at 60 mg QD (Cohort 2). Following a review of efficacy and safety, an additional dosing cohort may be evaluated. The primary endpoint is complete response (CR) rate at three months. Secondary endpoints include time to recurrence, the median duration of response, recurrence free survival (RFS), progression free survival (PFS), safety and tolerability.
o
Cleared Phase 2 ACH IND with US FDA – BEACH301. The study is 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. The study will initially enroll a safety sentinel cohort of up to 3 treatment-naïve participants per dose level in children ages 5 to 10.

o
Reported Interim Clinical Proof-of-Concept Results in mUC Patients – SURF301. TYRA-300 demonstrated encouraging preliminary anti-tumor activity in a heavily pre-treated population: at ≥ 90 mg 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 QD doses, with infrequent FGFR2/FGFR1-associated toxicities (data cutoff of August 15, 2024). TYRA-300 is being evaluated in Part B of SURF301 (NCT05544552) at potentially therapeutic QD doses in preparation for potential future Phase 2 studies.

TYRA-200

•
Advanced Phase 1 SURF201 Study. TYRA-200 is an FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations and resistance mutations. 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 pharmacokinetics of TYRA-200 and determine the optimal and maximum tolerated dose and recommended Phase 2 dose, as well as evaluate the preliminary antitumor activity of TYRA-200. 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

•
Cleared Phase 1 IND with US FDA – SURF431. TYRA-430 is an oral, 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

•
Strengthened Leadership Team and Board of Directors. In 2024, TYRA appointed Doug Warner, MD, as Chief Medical Officer, and Erik Goluboff, MD, as SVP, Clinical Development to lead the Company’s oncology strategy and clinical development plans. In 2025, TYRA appointed accomplished drug developer Adele Gulfo to its Board of Directors, Sinette Heys as SVP, Clinical Operations to lead the Company’s clinical operations team, and Will Charlton, MD, as SVP, Clinical Development to lead the Company’s skeletal dysplasia clinical development group.

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.

Fourth Quarter and Full-Year 2024 Financial Results

•
Cash, Cash Equivalents and Short-Term Investments. As of December 31, 2024, TYRA had cash, cash equivalents, and marketable securities of $341.4 million, compared to $203.5 million at the end of 2023. The increase was primarily due to the completion of a private placement financing for net proceeds of $199.6 million in the first quarter of 2024. The Company’s current cash, cash equivalents and marketable securities are expected to allow TYRA to execute on its plans through at least 2027.
•
Research and Development (R&D) Expenses. Research and development expenses for the three months ended December 31, 2024 were $22.2 million compared to $20.7 million for the same period in 2023, and $80.1 million for the full year 2024 compared to $62.5 million for the same period in 2023. The increases were primarily driven by increased expenses incurred in connection with our ongoing and planned clinical trials and personnel-related costs, including stock-based compensation, partially offset by decreased drug manufacturing and preclinical costs.
•
General and Administrative (G&A) Expenses. General and administrative expenses for the three months ended December 31, 2024 were $7.6 million compared to $5.0 million for the same period in 2023, and $24.1 million

for the full year 2024 compared to $17.4 million for the same period in 2023. The increases were primarily driven by increased personnel-related costs, including stock-based compensation.
•
Net Loss. Fourth quarter 2024 net loss was $25.6 million compared to $22.8 million for the same period in 2023, and $86.5 million for the full year 2024 compared to $69.1 million for the same period in 2023.

In recent years, cervical cancer incidence and mortality rates have increased in Japan, particularly among women under age 50.i,ii,iii Moreover, patients with recurrent or metastatic cervical cancer whose disease has progressed after first-line therapy have limited treatment options.

"Patients with advanced or recurrent cervical cancer, in general, have a poor prognosis. The advent of new treatment options, especially for second-line or later treatment, is much needed," said Aikou Okamoto, M.D., Ph.D., Chief Professor, Department of Obstetrics and Gynecology at The Jikei University School of Medicine. "Cervical cancer treatment has advanced in recent years, but it is very meaningful that the approval of tisotumab vedotin as an ADC has increased the number of treatment options with a new mechanism of action that is expected to prolong overall survival. This is good news for patients and healthcare professionals."

The approval is based on data from the randomized, open-label, global Phase 3 innovaTV 301 clinical trial that evaluated the efficacy and safety of TIVDAK compared to chemotherapy in patients with advanced or recurrent cervical cancer who were previously treated with chemotherapy. The trial included 502 patients, 101 of which were Japanese. The trial met its primary endpoint of overall survival (OS), demonstrating a 30% reduction in risk of death (HR: 0.70 [95% CI: 0.54-0.89], two-sided p=0.0038) compared to chemotherapy. Median OS was 11.5 months [95% CI: 9.8-14.9] among patients treated with TIVDAK compared to 9.5 months [95% CI: 7.9-10.7] for patients who received chemotherapy. Secondary endpoints of progression-free survival (PFS) and confirmed objective response rate (ORR) were also met.

Adverse drug reactions occurred in 219 (87.6%) of 250 patients (including 50 Japanese patients) treated with TIVDAK. The most common (≥20%) adverse reactions included conjunctivitis (n=76; 30.4%), nausea (n=73; 29.2%), peripheral sensory neuropathy (n=67; 26.8%), alopecia (n=61; 24.4%), and epistaxis (n=57; 22.8%), at the data cutoff date of July 24, 2023.

"As a company, we understand the urgent need for patients with advanced cervical cancer whose disease has progressed," said Judith Klimovsky, M.D., Executive Vice President and Chief Development Officer of Genmab.

The innovaTV 301 trial (NCT04697628) is a global, 1:1 randomized, open-label Phase 3 trial evaluating tisotumab vedotin versus investigator’s choice of single agent chemotherapy (topotecan, vinorelbine, gemcitabine, irinotecan or pemetrexed) in 502 patients with recurrent or metastatic cervical cancer who received one or two prior systemic regimens in the recurrent or metastatic setting.

Patients with recurrent or metastatic cervical cancer with squamous cell, adenocarcinoma or adenosquamous histology, and disease progression during or after treatment with chemotherapy doublet +/- bevacizumab and an anti-PD-(L)1 agent (if eligible) are included. The primary endpoint was overall survival. The main secondary outcomes were progression-free survival and objective response rate.

The study was conducted by Seagen, which was acquired by Pfizer in December 2023, in collaboration with Genmab, European Network of Gynaecological Oncological Trial Groups (ENGOT, study number ENGOT cx-12) and the Gynecologic Oncology Group (GOG) Foundation (study number GOG 3057), as well as other global gynecological oncology cooperative groups.

About Tisotumab Vedotin
Tisotumab vedotin (approved under the brand name TIVDAK in the U.S. and Japan) is an antibody-drug conjugate (ADC) composed of Genmab’s human monoclonal antibody directed to tissue factor (TF) and Pfizer’s ADC technology that utilizes a protease-cleavable linker that covalently attaches the microtubule-disrupting agent monomethyl auristatin E (MMAE) to the antibody. Nonclinical data suggest that the anticancer activity of tisotumab vedotin is due to the binding of the ADC to TF-expressing cancer cells, followed by internalization of the ADC-TF complex and release of MMAE via proteolytic cleavage. MMAE disrupts the microtubule network of actively dividing cells, leading to cell cycle arrest and apoptotic cell death. In vitro, tisotumab vedotin also mediates antibody-dependent cellular phagocytosis and antibody-dependent cellular cytotoxicity.
