Leap Therapeutics Reports Fourth Quarter and Full Year 2022 Financial Results

CAMBRIDGE, Mass., March 24, 2023 /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, 2022.

Leap Highlights: 

• Acquired Flame Biosciences, adding FL-301, a clinical stage anti-Claudin18.2 antibody, and preclinical antibody programs targeting Claudin18.2/CD137 and GDF15 to Leap's pipeline
  
  
  
  
• Presented clinical data from Part B of the Phase 2 DisTinGuish study of DKN-01 plus tislelizumab in gastroesophageal (GEA) cancer patients whose tumors express high levels of DKK1 (DKK1-high) and preclinical data supporting the activity of DKN-01 in colorectal cancer (CRC) at the Society for Immunotherapy of Cancer (SITC) Annual Meeting
  
  
  
  
• Enrolled the first patient into Part C of the DisTinGuish study, the randomized controlled trial of DKN-01 plus tislelizumab and chemotherapy in first-line GEA cancer patients
  
  
  
  
• Enrolled the first patient into the Phase 2 DeFianCe study of DKN-01 in second-line CRC patients
  
  
  
  
• Promotion of Jason Baum, Ph.D. to Chief Scientific Officer, effective April 1, 2023

"Over the past year, we advanced DKN-01, our anti-DKK1 antibody, into its first randomized controlled clinical trial in gastric cancer, entered into the new indication of colorectal cancer, and facilitated an endometrial cancer investigator-sponsored trial. We enhanced Leap's pipeline and financial strength through the acquisition of Flame Biosciences, which included FL-301, a clinical stage anti-Claudin18.2 antibody, preclinical programs targeting Claudin18.2/CD137 and GDF15, as well as approximately $50 million in cash," said Douglas E. Onsi, President and Chief Executive Officer of Leap. "In 2023, we are focused on executing our development plan for DKN-01 by completing enrollment in Part C of the DisTinGuish study and Part A of the DeFianCe study, with the objective of presenting new data over the course of the year and identifying a new strategic partner as data is generated. Our plan for our Claudin18.2 and GDF15 programs is to generate additional preclinical data to differentiate these antibodies from their competitors and to prepare for future clinical trials, while our collaborator continues a monotherapy study of FL-301 in China. We are looking forward and fully committed to our mission to acquire and develop a pipeline of biomarker-focused antibody therapies for cancer patients."

Business Update

• Leap completed the acquisition of Flame Biosciences and added FL-301 and two preclinical antibody programs to Leap's pipeline. In January 2023, Leap acquired Flame and its assets, including FL-301, its clinical stage anti-Claudin18.2 monoclonal antibody, FL-302, its preclinical anti-Claudin18.2/CD137 bispecific monoclonal antibody, FL-501, its preclinical anti-GDF15 monoclonal antibody, and cash of approximately $50 million as of December 31, 2022. In the merger, Leap issued approximately 19,794,373 shares of its common stock and approximately 136,833 shares of a newly designated Series X non-voting convertible preferred stock to Flame stockholders. Leap will seek stockholder approval for the conversion of the preferred stock into common stock, pursuant to the terms of the Certificate of Designation and Nasdaq rules, at the 2023 Annual Meeting of Stockholders, which is expected to be held in June.  Subject to and upon receipt of stockholder approval for such conversion, the 136,833 shares of Series X non-voting convertible preferred stock will convert into 136,833,000 shares of common stock of Leap.
  
  
  
  
• Leap provided an update on the agreement with BeiGene. In March 2023, Leap announced that BeiGene's option under the Exclusive Option and License Agreement between Leap and BeiGene granting rights in certain Asian territories to DKN-01 has expired in accordance with the terms of the agreement. Leap and BeiGene will continue to collaborate on the ongoing Part C of the DisTinGuish trial, a randomized controlled trial of DKN-01 in combination with tislelizumab and chemotherapy in first-line gastric cancer patients, as a clinical collaboration with BeiGene supplying tislelizumab.
  
  
  
  
• Promotion of Jason Baum, Ph.D. to Chief Scientific Officer. Dr. Baum has served as our Vice President and Head of Translational Research since August 2020 and is being promoted to Chief Scientific Officer effective April 1, 2023.

DKN-01 Development Update

• Updated data from Part B of the DisTinGuish Study of DKN-01 plus tislelizumab in second-line patients with advanced GEA cancer whose tumors express high levels of DKK1, presented at the SITC Annual Meeting.
  
  
  
  
• DKN-01 and tislelizumab were well tolerated at both 300mg and 600mg DKN-01 doses with no Grade 5 treatment-emergent AEs (TEAE) and no TEAEs leading to study drug discontinuation or dose reduction
• In evaluable anti-PD-1/PD-L1 naïve mITT population (n=43), 27% overall response rate (ORR) and 43% disease control rate (DCR), exceeding the benchmark studies for anti-PD-1 monotherapy
• In DKK1-high/PD-L1-high CPS ≥ 10 patients: 55% ORR, 73% DCR, 7.7 months median progression-free survival (PFS), median overall survival (OS) not reached
• In DKK1-high/PD-L1 CPS > 1 and < 10 patients: 8% ORR, 1.4 months PFS, 5.2 months OS
• In DKK1-high/PD-L1-negative CPS < 1 patients: 27% ORR, 1.4 months PFS, 3.9 months OS
  
  
  
  
• New preclinical data in CRC models, presented at the SITC Annual Meeting.
• DKN-01 additive activity with 5-fluorouracil (5FU) and can overcome 5FU-resistance in two xenograft models, resulting in tumor regressions. 5FU-resistant models are reflective of a second-line CRC population currently being recruited in the DeFianCe study.
• Treatment with DKN-01 as monotherapy or in combination with anti-PD-1 resulted in tumor regression in a CT26 syngeneic CRC model.
  
  
  
  
• Announced first patient enrolled in randomized, controlled Part C of the DisTinGuish Study. Part C of the DisTinGuish study will enroll approximately 160 first-line, HER2-negative patients who have had no prior therapy for unresectable locally advanced or metastatic G/GEJ adenocarcinoma and randomized on a 1:1 basis to DKN-01 in combination with tislelizumab and chemotherapy compared to tislelizumab and chemotherapy. Enrollment in Part C is currently expected to be completed in late 2023, with initial response rate data expected to be available year end 2023/early 2024 and PFS data in 2024.
  
  
  
  
• Announced first patient enrolled in DeFianCe Study of DKN-01 in combination with standard of care bevacizumab and chemotherapy in second-line CRC patients. The DeFianCe study (NCT05480306) is a Phase 2 study of DKN-01 in combination with bevacizumab and chemotherapy in patients with advanced CRC who have received one prior systemic therapy. The study is designed with an initial approximately 20 patient Part A cohort and to then expand into a 130 patient Part B randomized controlled trial. Enrollment in Part A is currently expected to be completed in the coming weeks, with initial data to be available mid-2023.

Selected Year-End and Fourth Quarter 2022 Financial Results

Net Loss was $54.6 million for the year ended December 31, 2022, compared to $40.6 million for the year ended December 31, 2021. The increase was primarily due to increased research and development expenses and general and administrative expenses, partially offset by an increase in interest income and increase in research and development incentive income.

There were no license revenues for the year ended December 31, 2022, compared to $1.5 million for the year ended December 31, 2021. The upfront payment was recognized in full as of December 31, 2021 for the agreement with BeiGene.

Research and development expenses were $45.0 million for the full year 2022, compared to $32.2 million for the same period in 2021. Research and development expenses were $11.0 million for the fourth quarter ended 2022, compared to $8.1 million for the same period in 2021. The increases were primarily due to an increase in manufacturing costs related to clinical trial material due to timing of manufacturing campaigns, an increase in clinical trial costs due to timing of patient enrollment and duration of patients on study, an increase in payroll and other related expenses due to an increase in headcount of research and development full time employees, and an increase in stock based compensation expense.

General and administrative expenses were $11.8 million for the full year 2021, compared to $10.8 million for the same period in 2021. General and administrative expenses were $2.9 million for the fourth quarter ended 2022, compared to $2.8 million for the same period in 2021. The increases were primarily due to an increase in payroll and other related expenses due to an increase in headcount of general and administrative full time employees, and an increase in stock based compensation expense.

Cash and cash equivalents totaled $65.5 million at December 31, 2022, which excludes the approximately $50 million cash received from the Flame Biosciences acquisition. Research and development incentive receivables totaled $2.1 million at December 31, 2022.
