Leap Therapeutics Reports Fourth Quarter and Full Year 2023 Financial Results

CAMBRIDGE, Mass., March 18, 2024 /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, 2023.

Leap Highlights:

    --  Presented new clinical data from Part A of the Phase 2 DeFianCe study
        evaluating DKN-01 in combination with standard of care bevacizumab and
        chemotherapy in second-line patients with advanced colorectal cancer, at
        the 2024 ASCO Gastrointestinal Cancers Symposium
    --  Completed enrollment in the randomized controlled Part C of the Phase 2
        DisTinGuish study evaluating DKN-01 in combination with tislelizumab and
        chemotherapy in patients with advanced gastroesophageal junction and
        gastric cancer

"As we reflect on the fourth quarter and the achievements of the past year, we are proud of the strides we've made in advancing DKN-01 and integrating our pipeline of earlier stage biomarker-targeted antibody therapies. The data from Part A of the DeFianCe study, demonstrating a 30% overall response rate and a 93% disease control rate in second-line colorectal cancer patients, showcases a strong foundation as we move into the randomized controlled Part B of the study," said Douglas E. Onsi, President and Chief Executive Officer of Leap. "Additionally, the completion of enrollment in Part C of the DisTinGuish study in first-line gastroesophageal junction and gastric cancer patients positions us to deliver the first randomized controlled data for DKN-01 starting in the middle of the year. As we look ahead to a data rich 2024, we remain focused on our mission to deliver new personalized medicines to patients fighting against cancer."

DKN-01 Development Update

    --  Presented initial clinical data from Part A of the DeFianCe Study of
        DKN-01 plus bevacizumab and chemotherapy in colorectal cancer (CRC)
        patients. The Company presented initial data from Part A of the DeFianCe
        study (NCT05480306), a Phase 2 study evaluating DKN-01 in combination
        with standard of care (SOC) bevacizumab and chemotherapy in second-line
        (2L) patients with advanced microsatellite stable (MSS) CRC patients at
        the 2024 American Society of Clinical Oncology (ASCO) Gastrointestinal
        Cancers Symposium, held in San Francisco on January 18-20, 2024 and
        during the Company's conference call on January 23, 2024.
    --  Key Findings:
    --  As of the December 6, 2023 data cutoff, across all patients enrolled
        (n=33):
        --  Overall response rate (ORR) among response-evaluable patients (n=27)
            was 30% and disease control rate (DCR) was 93%, including 8 partial
            responses (PR) and 17 patients with a best response of stable
            disease (SD)
        --  Median progression-free survival (PFS) was 6.3 months
        --  9 patients remained on therapy and were beyond 8.5 months
    --  Enhanced activity in patients with left-sided tumors (n=25), a group
        that has more frequent activation of the Wnt pathway modulated by DKK1
        --  33% ORR and 100% DCR in response-evaluable population (7 PRs, 14
            SDs)
        --  Preliminary median PFS of 8.6 months (9 patients continuing therapy
            within subgroup)
    --  Compelling ORR, DCR and PFS in patients with rectal/rectosigmoid
        carcinomas (n=15), a population with increasing incidence among young
        people and shown to have the highest DKK1 levels:
        --  46% ORR and 100% DCR in response-evaluable population (6 PRs, 7 SDs)
        --  Preliminary median PFS of 9.4 months (6 patients continuing therapy
            within subgroup)
        --  Higher baseline plasma DKK1 levels correlated with improved
            responses
    --  DKN-01 plus bevacizumab and chemotherapy was well-tolerated, with a
        majority of DKN-01 related events being low grade (Grade 1/2)

The Company expects the 130 patient randomized controlled Part B to complete enrollment in mid-2024. As of March 15, 2024, 80 patients have enrolled in Part B.

    --  Announced completion of enrollment in the randomized controlled Part C
        of the DisTinGuish study evaluating DKN-01 in combination with
        tislelizumab, BeiGene's anti-PD-1 antibody, and chemotherapy in patients
        with advanced gastroesophageal junction and gastric cancer. Part C of
        the DisTinGuish study (NCT0436380) is a Phase 2, randomized, open-label,
        multicenter study of DKN-01 in combination with tislelizumab and
        chemotherapy in first-line patients with advanced gastroesophageal
        adenocarcinoma. Part C enrolled 170 first-line, HER2-negative patients
        randomized 1:1 to evaluate DKN-01 in combination with tislelizumab and
        SOC chemotherapy, compared to tislelizumab and SOC chemotherapy alone.
        The primary objective is progression-free survival (PFS) in DKK1-high
        and in all patients. Secondary objectives of Part C include overall
        survival and objective response rate as measured by RECIST v1.1 in
        DKK1-high and in all patients. The Company expects to report initial
        data from Part C of the DisTinGuish study in mid-2024.

Selected Year-End and Fourth Quarter 2023 Financial Results

Net Loss was $81.4 million for the year ended December 31, 2023, compared to $54.6 million for the year ended December 31, 2022. The increase was due to in-process research and development acquired in the Flame merger which was expensed during the year ended December 31, 2023, costs incurred in connection with our research and development programs, and from general and administrative costs associated with our operations.

Research and development expenses were $73.2 million for the full year 2023, compared to $45.0 million for the same period in 2022. Research and development expenses were $11.7 million for the fourth quarter ended 2023, compared to $11.0 million for the same period in 2022. The increases for the full year 2023 were primarily due to in-process research and development acquired in the Flame merger, an increase in clinical trial costs, and an increase in payroll and other related expenses due to an increase in headcount of research and development full-time employees.

General and administrative expenses were $13.8 million for the full year 2023, compared to $11.8 million for the same period in 2022. General and administrative expenses were $3.1 million for the fourth quarter ended 2023, compared to $2.9 million for the same period in 2022. The increases for the full year 2023 were primarily due to costs associated with our business development activities and an increase in payroll and other related expenses due to an increase in headcount of general and administrative full-time employees.

Cash and cash equivalents totaled $70.6 million at December 31, 2023. Research and development incentive receivables totaled $0.8 million at December 31, 2023.
