Leap Therapeutics Announces Collaboration With EORTC to Evaluate DKN-01 in Combination with PD-L1 Cancer Immunotherapy and Chemotherapy In Esophagogastric and Biliary Tract Cancers

CAMBRIDGE, Mass., Sept. 08, 2017 (GLOBE NEWSWIRE) — Leap Therapeutics, Inc. (NASDAQ:LPTX), a biotechnology company developing targeted and immuno-oncology therapeutics, today announced an immunotherapy collaboration with the European Organisation for Research and Treatment of Cancer (EORTC). The cooperative group sponsored clinical trial will evaluate DKN-01 in combination with atezolizumab (TECENTRIQ®) +/- paclitaxel in advanced esophagogastric malignancies and DKN-01 + atezolizumab in advanced biliary tract cancers at EORTC centers across Europe. Roche will supply atezolizumab to the EORTC for this study collaboration.

“DKN-01 has shown promising activity in advanced esophagogastric and biliary tract cancers. Given the emerging role of Wnt/beta-catenin in immuno-oncology, we believe that DKN-01 could be a novel immunotherapy for these patients and look forward to evaluating its activity when combined with atezolizumab and paclitaxel,” commented Markus Moehler, M.D., Ph.D, Professor of Gastrointestinal (GI) Oncology, principal investigator of the study and member of the GI group of the EORTC.

“We look forward to expanding our clinical studies into Europe with the support of the EORTC Gastrointestinal tract cancer Group (GITCG). This immunotherapy collaboration further expands our vision as we look to build upon the foundational activity we have seen with DKN-01 and backbone chemotherapy in these malignancies with significant unmet medical need,” commented Cynthia Sirard, M.D., Vice President, Clinical Development of Leap Therapeutics. 

The study is expected to begin enrolling patients in 2018 and aims to understand the synergy between DKN-01, a Wnt-targeted therapy, and an immune checkpoint inhibitor with and without chemotherapy. The study will explore the efficacy and safety of the combination as well as aim to identify biomarkers.

About Leap Therapeutics
Leap Therapeutics’ (NASDAQ:LPTX) most advanced clinical candidate, DKN-01, is a humanized monoclonal antibody targeting the Dickkopf-1 (DKK1) protein. DKN-01 is in clinical trials in patients with esophagogastric cancer, alone and in combination with paclitaxel, and in patients with biliary tract cancer, in combination with gemcitabine and cisplatin. An investigator-initiated study of DKN-01 will be conducted in hepatocellular carcinoma patients, in combination with sorafenib.  DKN-01 has demonstrated single agent activity in non-small cell lung cancer patients. Leap’s second clinical candidate, TRX518, is a novel, humanized GITR agonist monoclonal antibody designed to enhance the immune system’s anti-tumor response that is in two monotherapy studies.  For more information about Leap Therapeutics, visit http://www.leaptx.com or our public filings with the SEC that are available via EDGAR at http://www.sec.gov or via http://www.investors.leaptx.com/.
