CAMBRIDGE, Mass., Sept. 30, 2024 /PRNewswire/ -- Leap Therapeutics, Inc. (Nasdaq: LPTX), a biotechnology company focused on developing targeted and immuno-oncology therapeutics, today announced that enrollment of 188 patients has been completed in the randomized controlled Part B of the DeFianCe study evaluating DKN-01, Leap's anti-Dickkopf-1 (DKK1) antibody, in combination with standard of care bevacizumab and chemotherapy as a second-line treatment for patients with advanced colorectal cancer (CRC).
"The completion of enrollment in Part B of the DeFianCe study marks a significant achievement and highlights the enthusiasm in the potential of DKN-01 from both patients and healthcare providers," said Cynthia Sirard, M.D., Chief Medical Officer of Leap. "The encouraging data from Part A of the study which showed clinically meaningful response rates and durable tumor reductions, as well as a favorable safety profile in advanced CRC patients, provides a strong foundation to the expanded Part B of the study. We look forward to sharing initial data from Part B, including the subpopulation of patients with left-sided CRC, in mid 2025."
The DeFianCe study (NCT05480306) is a Phase 2, open-label, global study of DKN-01 in combination with standard of care bevacizumab and chemotherapy in patients with advanced CRC who have received one prior systemic therapy for advanced disease. Part B of the study expanded from a 130 to a 188-patient randomized controlled trial, with the primary endpoint being progression free survival (PFS). An additional primary endpoint will measure PFS in the subpopulation of patients with left-sided CRC. Secondary objectives include objective response rate, duration of response, and overall survival.
