“Leap Therapeutics has achieved a milestone in our growth by becoming a public company,” commented Christopher K.

Leap’s Pipeline

Leap Therapeutics is conducting clinical studies with two best-in-class therapeutics.


DKN-01 is a humanized monoclonal antibody that binds to and blocks the action of the Dickkopf-1 (DKK1) protein, a modulator of Wnt/Beta-catenin signaling. DKK1 expression has been associated with poor prognosis in multiple cancers. Recent literature suggests DKK1has an important role in tumor cell signaling and in mediating an immuno-suppressive tumor microenvironment. DKN-01 is being studied in clinical trials in patients with esophageal, gastric, and biliary tract cancers. DKN-01 has demonstrated single agent activity in non-small cell lung cancer patients.


TRX518 is a humanized monoclonal antibody with agonist activity targeting glucocorticord-inducible TNF-superfamily receptor (GITR). TRX518 is engineered to enhance immune responses to cancer. In clinical studies, a single-dose of TRX518 is associated with a reduction in immunosuppressive cells known as T regulatory cells. TRX518 is being studied in two ongoing repeat-dose clinical trials in patients with advanced solid tumor malignancies.
