Leap Therapeutics Announces Completion of Enrollment for First-Line Patient Cohort
in Study of DKN-01 in Combination with Tislelizumab
for the Treatment of Gastric or Gastroesophageal Junction Cancer
Cambridge, MA – April 1, 2021 – Leap Therapeutics, Inc. (Nasdaq:LPTX), a biotechnology company focused on developing targeted and immuno-oncology therapeutics, today announced the completion of enrollment for the first-line patient cohort in the DisTinGuish study, a clinical trial evaluating Leap's anti-Dickkopf-1 (DKK1) antibody, DKN-01, in combination with tislelizumab, BeiGene Ltd.'s anti-PD-1 antibody, with or without chemotherapy, in patients with gastric or gastroesophageal junction cancer (G/GEJ).
“The completion of enrollment for the first-line patients in the DisTinguish study is an important milestone for the DKN-01 and tislelizumab combination development program,” said Cynthia Sirard, M.D., Chief Medical Officer of Leap Therapeutics. “In collaboration with our partner, BeiGene, we are committed to realizing the potential of DKN-01 as part of a new combination therapy with tislelizumab aimed at treating gastric and gastroesophageal junction cancer patients, where a high global unmet medical need remains.”
The DisTinGuish trial (NCT04363801) is a Phase 2a, nonrandomized, open-label, multicenter study of DKN-01 in combination with tislelizumab with or without chemotherapy as first-line or second-line therapy in adult patients with inoperable, locally advanced G/GEJ adenocarcinoma. The study, which will be conducted in two parts in the United States and the Republic of Korea, includes up to 24 patients with first-line G/GEJ cancer and up to 48 patients with second-line G/GEJ cancer whose tumors express high levels of DKK1. Initial data is expected in the second half of 2021. Leap is conducting this combination study as part of an exclusive option and license agreement with BeiGene for the development of DKN-01 in Asia (excluding Japan), Australia, and New Zealand. Leap retains exclusive rights for the development, manufacturing, and commercialization of DKN-01 for the rest of the world.
About gastric / gastroesophageal junction cancer
Gastric adenocarcinoma (gastric cancer) remains one of the most common and deadly cancers worldwide, especially among older malesi. Based on GLOBOCAN 2018 data, stomach cancer is the 5th most common neoplasm and the 3rd most deadly cancer, with an estimated 783,000 deaths globally in 2018i. Ninety-five percent of cancers of the stomach are adenocarcinomasi. Gastric cancer incidence and mortality are highly variable by region and highly dependent on diet and Helicobacter pylori infectioni. The gastroesophageal junction (GEJ) is the area where the esophagus and stomach join together. Given its anatomic location, GEJ adenocarcinomas have often been grouped together with either esophageal or gastric cancers in clinical trials.
DKN-01 is a humanized monoclonal antibody that binds to and blocks the activity of the Dickkopf-1 (DKK1) protein. DKK1 modulates the Wnt/Beta-catenin and PI3kinase/AKT signaling pathways, which have an important role in tumor cell signaling and in mediating an immuno-suppressive tumor microenvironment through enhancing the activity of myeloid-derived suppressor cells and downregulating NK cell ligands on tumor cells. The U.S. Food and Drug Administration has granted DKN-01 Orphan Drug Designation for the treatment of gastric and gastroesophageal junction cancer and Fast Track Designation in combination with tislelizumab for the treatment of patients with gastric and gastroesophageal junction adenocarcinoma whose tumors express high DKK1 protein, following disease progression on or after prior fluoropyrimidine- and platinum-containing chemotherapy and if appropriate, human epidermal receptor growth factor (HER2)/neu-targeted therapy.
