Patient follow-up is ongoing in Part C of the Phase 2 DisTinGuish study, assessing DKN-01 with tislelizumab and chemotherapy in first-line GEJ and gastric cancer (搜索), with data anticipated late 2024 or early 2025.
Leap Therapeutics is advancing FL-501, a monoclonal antibody targeting GDF-15 (搜索), into development based on promising preclinical data for treating cachexia (搜索) and other GDF-15-driven diseases.
Leap Therapeutics, Inc. (Nasdaq:LPTX) has announced the completion of enrollment in the expanded randomized controlled Part B of the Phase 2 DeFianCe study. This study is evaluating DKN-01, Leap's anti-DKK1 (搜索) monoclonal antibody, in combination with standard-of-care bevacizumab and chemotherapy in second-line patients with advanced colorectal cancer (搜索) (CRC). Initial data from this part of the study are expected in mid-2025.
Patient follow-up is also continuing in the randomized controlled Part C of the Phase 2 DisTinGuish study. This trial is assessing DKN-01 in combination with tislelizumab and chemotherapy in first-line patients with advanced gastroesophageal junction (GEJ) and gastric cancer (搜索). The company anticipates sharing initial randomized controlled data from the DisTinGuish study in late 2024 or early 2025.
Advancing FL-501 Development
Leap Therapeutics has initiated the development of FL-501, its anti-GDF-15 (搜索) monoclonal antibody. Preclinical data suggest that FL-501 could be a potential best-in-class antibody for neutralizing GDF-15 to treat patients with cachexia (搜索) and other GDF-15-driven diseases. FL-501 is also being explored for its potential to enhance the activity of the immune system within the tumor microenvironment. Preclinical models of cachexia have shown that FL-501 increases body weight and restores muscle mass.
