"We look forward to continuing to collaborate with BeiGene to execute on our first randomized controlled trial for DKN-01 in first-line gastric cancer patients," said Douglas E. Onsi, President and Chief Executive Officer of Leap. "With global rights to DKN-01 and a cash runway that was enhanced into mid-2025 by our recent acquisition of Flame Biosciences, we will look to identify a new strategic partner as we generate new clinical data from our ongoing studies in first-line gastric cancer patients, second-line colorectal cancer patients, and an investigator-sponsored study in endometrial cancer patients. We will also continue the development of the newly-acquired Claudin18.2 programs as part of our focus on biomarker-targeted antibody therapies for cancer patients, particularly those with GI cancers."
