Leap Therapeutics Reports Fourth Quarter and Full Year 2024 Financial Results

Leap to host a conference call to present updated CRC clinical data today, March 26, 2025, at 8:00 a.m. ET , /PRNewswire/ -- Leap Therapeutics, Inc. (Nasdaq:LPTX), a biotechnology company focused on developing targeted and immuno-oncology therapeutics, today reported financial results for the fourth quarter and year ended December 31, 2024. Leap Highlights: Reported positive updated data from Part B of the Phase 2 DeFianCe study of sirexatamab (DKN-01) in second-line patients with advanced microsatellite stable (MSS) colorectal cancer (CRC) confirming: Statistically significant 32% higher overall response rate (ORR), 3.5 month longer progression-free survival (PFS), and longer overall survival (OS) in patients with high DKK1 levels Statistically significant 22% higher ORR and 2.6 month longer PFS in patients who had not had prior anti-VEGF therapy FL-501 abstract accepted for poster presentation at the 2025 American Association for Cancer Research (AACR) Annual Meeting. "In 2024, we continued to advance sirexatamab, our anti-DKK1 antibody, through Phase 2 randomized controlled clinical trials as part of our mission to bring personalized medicines to patients fighting against cancer. In particular, the updated data from Part B of the DeFianCe study that we announced today demonstrated significantly higher ORR and longer PFS for sirexatamab in patients who have high levels of DKK1 or who have not had prior anti-VEGF therapy, two exploratory populations with strong scientific rationale that each represent 25-50% of the second-line CRC market," said Douglas E. Onsi, President and Chief Executive Officer of Leap. "We believe that there is a compelling opportunity to move forward with a registrational study for sirexatamab in patients with CRC and to advance FL-501 towards clinical trials." DKN-01 Development Update Reported updated clinical data from Part B of the DeFianCe Study of sirexatamab plus bevacizumab and chemotherapy in CRC patients. Today, the Company announced updated preliminary data from Part B of the DeFianCe study (NCT05480306), a Phase 2, open-label, global study of sirexatamab in combination with bevacizumab and chemotherapy (Experimental Arm) compared to bevacizumab and chemotherapy (Control Arm) in patients with MSS CRC who have received one prior systemic therapy for advanced disease. In the updated data announced today, Patients with high DKK1 levels, either at the upper quartile or above the median, treated in the sirexatamab Experimental Arm had significantly improved ORR, PFS, and OS compared to the Control Arm. In patients who had not received prior anti-VEGF therapy, the sirexatamab Experimental Arm had significantly improved ORR and PFS compared to the Control Arm, with an early advantage in OS. Across the intent-to-treat population, the sirexatamab Experimental Arm had improved ORR compared to the Control Arm, with PFS and OS maturing with a higher number of patients continuing to benefit on the sirexatamab Experimental Arm. The strong signal from the DeFianCe study supports a registrational Phase 3 clinical trial to evaluate sirexatamab plus bevacizumab and chemotherapy in second-line MSS CRC patients with high DKK1 levels or in patients who have not received prior anti-VEGF therapy. With approximately 30,000 second-line treated CRC patients in the US and 160,000 in the next 7 largest markets, sirexatamab has a large market opportunity in the 25-50% of patients who have high DKK1 levels or in the approximately 50% of patients who did not receive prior anti-VEGF therapy. In addition, the outcomes in patients with no prior anti-VEGF therapy provides an opportunity to move into treating first-line CRC patients, where there are an estimated 45,000 patients in the US and 265,000 in the next 7 largest markets who receive therapy for their advanced disease. Leap has engaged a leading financial advisor to explore business development opportunities to further the development of sirexatamab. Pipeline Update Presenting preclinical FL-501 data at the 2025 American Association for Cancer Research (AACR) Annual Meeting. Preclinical data from FL-501, a potential best-in-class monoclonal antibody designed to neutralize GDF-15 to treat patients with cachexia and other GDF-15-driven diseases, will be featured during a poster session at the 2025 AACR Annual Meeting taking place April 25-30 in Chicago. In addition, manufacturing and non-clinical development continues with the goal of beginning a clinical trial in 2026. Conference Call Leap's management team will host a conference call today, March 26, 2025 at 8:00 a.m. Eastern Time to further discuss the data. The conference call will be broadcast live in listen-only mode and can be accessed via the webcast URL: https://edge.media-server.com/mmc/p/t6576mgc.

Selected Year-End and Fourth Quarter 2024 Financial Results Net Loss was $67.6 million for the year ended December 31, 2024, compared to $81.4 million for the year ended December 31, 2023. The decrease was primarily due to a decrease in research and development expenses. Research and development expenses were $57.2 million for the full year 2024, compared to $73.2 million for the same period in 2023. Research and development expenses were $13.1 million for the fourth quarter ended 2024, compared to $11.7 million for the same period in 2023. The decreases for the full year 2024 were primarily due to in-process research and development acquired in the Flame merger which were expensed in the year ended December 31, 2023. General and administrative expenses were $12.8 million for the full year 2024, compared to $13.8 million for the same period in 2023. General and administrative expenses were $3.0 million for the fourth quarter ended 2024, compared to $3.1 million for the same period in 2023. The decreases for the full year 2024 were primarily due to a decrease in professional fees due to lower finance and legal costs. Cash and cash equivalents totaled $47.2 million at December 31, 2024.
