Leap Therapeutics Reports Full Year 2016 Financial Results and Progression-Free Survival Data in Advanced Biliary Tract Cancers


CAMBRIDGE, Mass., March 31, 2017 (GLOBE NEWSWIRE) -- Leap Therapeutics, Inc.(Nasdaq:LPTX), a biotechnology company developing targeted and immuno-oncology therapeutics, today reported financial results for the year ended December 31, 2016 and top-line progression-free survival (PFS) data.

Preliminary median progression-free survival was 9.4 months in Leap’s clinical trial evaluating DKN-01 in combination with standard of care chemotherapy in patients with advanced biliary tract cancers. The median PFS for standard of care chemotherapy has been reported to be six to eight months. Data from the study has been submitted for presentation at an upcoming medical conference.

“2016 was an important year for Leap. We became a public company and we generated exciting clinical data from our multiple ongoing clinical studies of two innovative cancer therapeutics,” said Christopher K. Mirabelli, Ph.D, Chief Executive Officer of Leap. “We are especially pleased with the PFS observed in patients with biliary cancers and the clinical data from our industry-leading GITR agonist program.”

About the DKN-01 P103 Clinical Trial

The open-label, dose-escalation study enrolled 27 patients with treatment-naïve advanced biliary tract cancer. Patients received two dose levels of DKN-01 in combination with gemcitabine and cisplatin. The primary objective of this study is to evaluate the safety, pharmacokinetics, and efficacy of DKN-01 in combination with gemcitabine and cisplatin. The study has recently been expanded to enroll an additional 20 patients to enhance biomarker collection and analysis.

2016 Accomplishments

  • Presented proof of concept clinical data of DKN-01 in advanced biliary tract and esophagogastric cancers with encouraging overall response and disease control rates at meetings of the European Society for Medical Oncology (ESMO), American Society for Clinical Oncology (ASCO), and the Cholangiocarcinoma Foundation.

  • Identified Wnt-pathway alterations as a potential genetically-defined population for DKN-01 development

  • Developed and presented first observed cases of human pharmacodynamic activity of GITR agonist TRX518 on immunosuppressive T cells.

  • Initiated two repeat-dose TRX518 studies in patients with refractory solid tumors.

  • Commenced trading on the Nasdaq Global Market in January 2017.

Selected Year-End 2016 Financial Results

Net loss was $25.6 million for the year ended December 31, 2016, compared to $12.1 million

for the year ended December 31, 2015.

Research and development expenses were $23.3 million for the full year 2016, compared to $10.4 million for the same period in 2015. This increase was primarily due to clinical development expenses and manufacturing costs of our clinical product candidates.

General and administrative expenses were $4.2 million for the full year 2016, compared to $1.5 million for the same period in 2015. This increase was primarily due to increased personnel and legal expenses to support the company’s expanding operations, including our acquisition of Macrocure Ltd.

The financial results presented for 2016 represent Leap Therapeutics as a private company, as the merger with Macrocure was completed on January 23, 2017.  The financial results presented also include an unaudited pro-forma calculation of Leap Therapeutics’ balance sheet to present the merger with Macrocure and the related transactions as if they had closed on December 31, 2016. The financial statements for the first quarter 2017 will reflect the actual transaction closing date and subsequent financial results as a public company.
