Leap Therapeutics Reports Second Quarter 2019 Financial Results

·                                          Positive data from DKN-01 plus KEYTRUDAÒ (pembrolizumab) combination study

·                                          First patients enrolled in TRX518 plus BAVENCIOÒ (avelumab) and cyclophoshamide combination study

Cambridge, MA — August 9, 2019 — Leap Therapeutics, Inc. (NASDAQ:LPTX), a biotechnology company developing targeted and immuno-oncology therapeutics, today reported financial results for the second quarter ended June 30, 2019.

“We recently presented positive data from our clinical study of DKN-01 plus KEYTRUDA which demonstrated higher survival and objective response outcomes in patients with advanced gastroesophageal junction and gastric cancer whose tumors expressed high levels of DKK1 (DKK1-high).  As we have seen with the single agent partial responses in patients with endometrial cancer, DKN-01’s activity continues to be impressive in biomarker-targeted patient populations,” commented Christopher K. Mirabelli, Ph.D, President and Chief Executive Officer of Leap Therapeutics. “In addition, we have enrolled our first patients in the triple chemoimmunotherapy study of TRX518 in combination with BAVENCIO and cyclophosphamide.”

Recent Developments

·                  DKN-01 CLINICAL INVESTIGATOR WEBCAST:  On August 6, 2019, Leap hosted a DKN-01 program update webcast with Samuel J. Klempner, MD, Assistant Professor, Massachusetts General Hospital Cancer Center and Harvard Medical School, and Rebecca C. Arend, MD, Assistant Professor and Associate Scientist, Gynecologic Oncology Clinic, UAB Comprehensive Cancer Center Experimental Therapeutics Program.  A replay of the webcast and the presentation slides are available under “Events & Presentations” in the Investor section of Leap’s website, https://www.leaptx.com/program-webcasts.

·                  DKN-01 in ESOPHAGOGASTRIC CANCER:  Leap presented data from the KEYNOTE-731 clinical study evaluating DKN-01 in combination with KEYTRUDA in patients with advanced esophagogastric cancer. In gastroesophageal junction and gastric cancer patients who had not received prior PD-1/PD-L1 therapy, the combination of DKN-01 plus KEYTRUDA demonstrated improved outcomes in patients whose tumors are DKK1-high. DKK1-high patients experienced 22.1 weeks median progression free survival (PFS) and 31.6 weeks median overall survival (OS), with a 50% overall response rate (ORR) and 80% disease control rate (DCR) in ten evaluable patients. DKK1-low patients experienced 5.9 weeks PFS and 17.4 weeks OS, with a 20% DCR in fifteen evaluable patients. PD-L1 Combined Positive Scores (CPS) did not predict efficacy to the combination of DKN-01 plus KEYTRUDA. In multi-variate analysis, DKK1-high status correlated with longer PFS independent of PD-L1 CPS.

·                  DKN-01 in GYNECOLOGICAL CANCERS:  The clinical study of DKN-01 as a monotherapy and in combination with paclitaxel in patients with advanced gynecological cancers has been expanded to include focused cohorts of patients with carcinosarcoma. Overall, ninety-six patients have been enrolled in the study, and enrollment is ongoing. Additional response and biomarker data will be available in September at the International Gynecologic Cancer Society Annual Global Meeting.

·                  TRX518 TRIPLE COMBINATION THERAPY:  Leap enrolled the first patients in the clinical trial evaluating TRX518 in combination with cyclophosphamide chemotherapy and BAVENCIO. Dose escalation in the study is ongoing.

·                  $21 MILLION EQUITY COMMITMENT FACILITY:  Leap entered into purchase agreements with Lincoln Park Capital Fund, LLC (LPC) pursuant to which Leap sold $1 million in common stock and has the option, but not the obligation, to sell to LPC up to an additional $20 million in shares of common stock in tranches over a twenty-four month period. The price of shares sold will be based on the market prices prevailing at the time of each sale to LPC. There is no upper limit as to the price per share that LPC may pay for future stock issuances under the agreement, and Leap will control the timing and amount of any future sales.

Selected Second Quarter 2019 Financial Results

Net loss was $8.4 million for the second quarter 2019, compared to $7.4 million for the same period in 2018. This increase was primarily due to an increase in clinical development expense and the recording of a loss in the second quarter 2018 as a result of a decrease in the fair value of the warrant liability.

Research and development expenses were $6.1 million for the second quarter 2019, compared to $4.2 million for the same period in 2018. This increase was primarily due to an increase in clinical trial expenses associated with an increase in patient enrollment and an increase in consulting fees and payroll expenses, partially offset by a decrease in manufacturing costs related to clinical trial material.

General and administrative expenses were $2.3 million for the second quarter 2019, compared to $2.6 million for the same period in 2018. This decrease was primarily due to a decrease in legal, audit and consulting fees.

Cash, cash equivalents and marketable securities totaled $15.7 million at June 30, 2019. Research and development incentive receivables, current and long term, totaled approximately $1.0 million at June 30, 2019. Subsequent to the end of the quarter, Leap announced the commitment facility with LPC and sold $1.0 million in common stock.
