CAMBRIDGE, Mass., Nov. 13, 2017 (GLOBE NEWSWIRE) -- Leap Therapeutics, Inc. (Nasdaq:LPTX), a biotechnology company developing targeted and immuno-oncology therapeutics, today reported financial results for the third quarter ended September 30, 2017. Leap additionally announced that the first patient has been dosed in a Phase 1/2 clinical trial evaluating Leap’s DKK1 antagonist, DKN-01, in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in patients with relapsed or refractory advanced esophagogastric adenocarcinoma.
“The use of checkpoint inhibitors has generated exciting responses in a minority of patients with advanced relapsed or recurrent esophagogastric cancer. We are hopeful that the addition of DKN-01 to pembrolizumab will expand the clinical benefit without added toxicity,” commented Dr. Samuel Klempner, Director of Precision Medicine at The Angeles Clinic and Research Institute and an investigator on the study.
“We have continued to advance development of both of our pipeline assets as we aim to build a world-class immuno-oncology company. This quarter we reported promising clinical activity for both assets and have begun the process to launch clinical studies exploring novel therapeutic combinations in targeted patient populations,” commented Christopher K. Mirabelli, Ph.D, President and Chief Executive Officer of Leap Therapeutics. “The combination study of DKN-01 with pembrolizumab in esophagogastric cancer is the first example of this strategy. We are eager to explore the complementary mechanism of action of DKN-01 and checkpoint inhibitors to enhance anti-tumor immune responses.”
The P102 esophagogastric cancer study is a multipart study evaluating DKN-01 as a monotherapy and in combination with paclitaxel or pembrolizumab in patients with advanced relapsed or refractory esophagogastric cancer. The combination arm evaluating DKN-01 with pembrolizumab includes both dose escalation and dose confirmation cohorts and is designed to evaluate the safety, pharmacokinetics and efficacy of the combination in patients with esophagogastric adenocarcinoma. The DKN-01+pembrolizumab study will enroll up to approximately 67 patients. The dose confirmation cohort (n=55) will include patients that are naïve (n=40) or refractory (n=15) to PD-1/ PD-L1 antagonists.
- Announced updated clinical efficacy data from the P102 clinical trial evaluating DKN-01 in combination with paclitaxel in patients with advanced relapsed or refractory esophagogastric cancer. The recent data indicated that 26% of patients on combination therapy had a partial response. When analyzed by prior taxane experience, patients had a response rate of 40.9% and 12.5%, a disease control rate of 72.7% and 45.8%, and a median progression-free survival of 17.0 and 9.7 weeks, in taxane-naïve patients and taxane-experienced patients, respectively. A patient on DKN-01 monotherapy achieved a partial response by central imaging analysis and has been on therapy for over one year. Enrollment in the study continues.
- Announced a collaborative-group sponsored study with the European Organisation for Research and Treatment of Cancer (EORTC) and Roche to evaluate DKN-01 in combination with TECENTRIQ ® (atezolizumab), a PD-L1 antagonist, ± paclitaxel in patients with advanced esophagogastric cancer or biliary tract cancer.
- Filed an IND application with the FDA to initiate a clinical trial of DKN-01 in patients with gynecological malignancies, a population known to have a high frequency of Wnt pathway mutations.
- Announced clinical data from the 003 repeat-dose clinical trial evaluating TRX518 monotherapy in patients with advanced solid tumors. The Part B expansion cohort has been fully enrolled and as of August 31 2017, 50% of patients experienced a best response of stable disease, 26% had progressive disease, and 24% were non-evaluable for response. Patient follow-up, biopsy, and biomarker analysis are ongoing. Signs of pharmacodynamic activity including CD8+ T cell activation have been observed.
- Announced the first combination study evaluating TRX518 in combination with a chemotherapy, gemcitabine, or in combination with immune checkpoint inhibitors in patients with advanced solid tumors.
Selected Third Quarter 2017 Financial Results
Net loss was $6.8 million for the third quarter of 2017, compared to $7.3 million for the same period in 2016.
Research and development expenses were $6.8 million for the third quarter 2017, compared to $5.7 million for the same period in 2016. This increase was primarily due to increased clinical trial expenses.
General and administrative expenses were $1.8 million for the third quarter 2017, compared to $1.4 million for the same period in 2016. This increase was primarily due to an increase in stock based compensation expense and increased headcount needed to support public company operations.
Cash, cash equivalents and marketable securities totaled $14.2 million at September 30, 2017. Research and development incentive receivables totaled $1.9 million.
