Under the terms of the collaboration, Leap will be conducting a Phase I/II clinical trial in advanced solid tumors including expansion populations in patients with relapsed/refractory ovarian, breast, and prostate cancers. The study is expected to begin enrolling patients in the first quarter of 2019.

"The combination of TRX518 with anti-PD-L1 immunotherapy and cyclophosphamide has a solid scientific rationale and we look to build upon our early clinical and preclinical data highlighting the potential benefits of such a combination," commented Cynthia Sirard, M.D., Vice President, Clinical Development of Leap Therapeutics.

"TRX518 has demonstrated encouraging potential with early clinical activity in patients with advanced solid tumors," said Chris Boshoff, M.D., Ph.D., Senior Vice President and Head of Immuno-oncology, Early Development and Translational Oncology, Pfizer Global Product Development. "This collaboration with Leap Therapeutics to evaluate TRX518 in combination with avelumab gives us the opportunity to investigate a potential novel immunotherapy treatment regimen as we pursue our mission of improving outcomes for patients living with hard-to-treat cancers."

"Combination therapy remains a major focus in our clinical development program for avelumab in an effort to advance the treatment landscape for patients with challenging cancers," said Alise Reicin, Head of Global Clinical Development at the Biopharma business of Merck KGaA, Darmstadt, Germany, which in the US and Canada operates as EMD Serono. "Through our collaboration with Leap Therapeutics, we are eager to further understand the potential of this novel immunotherapy combination in this patient population."

Avelumab has received accelerated approval** by the US Food and Drug Administration (FDA) for the treatment of patients with metastatic Merkel cell carcinoma (MCC) and previously treated patients with locally advanced or metastatic urothelial carcinoma (mUC), and is under further clinical evaluation across a range of tumor types under a global strategic alliance between Merck KGaA, Darmstadt, Germany, and Pfizer.

*Avelumab is under clinical investigation for treatment of solid tumors and hematological malignancies in combination with TRX518 and has not been demonstrated to be safe and effective for these uses. There is no guarantee that avelumab will be approved for solid tumors or hematological malignancies by any health authority worldwide.

About Avelumab

Avelumab is a human anti-programmed death ligand-1 (PD-L1) antibody. Avelumab has been shown in preclinical models to engage both the adaptive and innate immune functions. By blocking the interaction of PD-L1 with PD-1 receptors, avelumab has been shown to release the suppression of the T cell-mediated antitumor immune response in preclinical models.1-3 Avelumab has also been shown to induce NK cell-mediated direct tumor cell lysis via antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro.3-5 In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

Avelumab is currently being evaluated in the JAVELIN clinical development program, which involves at least 30 clinical programs, including seven Phase III trials, and over 8,600 patients across more than 15 different tumor types. For a comprehensive list of all avelumab trials, please visit clinicaltrials.gov.

Approved Indications in the US**

The US Food and Drug Administration (FDA) granted accelerated approval for avelumab (BAVENCIO) for the treatment of (i) mMCC in adults and pediatric patients 12 years and older and (ii) patients with locally advanced or metastatic urothelial carcinoma (UC) who have disease progression during or following platinum-containing chemotherapy, or who have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. These indications were approved under accelerated approval based on tumor response rate and duration of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

Important Safety Information from the US FDA Approved Label

On July 23, 2018 Hutchison China MediTech Limited ("Chi-Med") (AIM/Nasdaq: HCM) has initiated a Phase Ib/II proof-of-concept study of sulfatinib in pancreatic neuroendocrine tumors ("NET") patients and in biliary tract cancer ("BTC") patients in the U.S.. Sulfatinib is an oral small molecule angio-immuno kinase inhibitor that can simultaneously block tumor angiogenesis and immune evasion (Press release, Hutchison China MediTech, JUL 23, 2018, https://www.chi-med.com/sulfatinib-poc-pnet-btc-us/ [SID1234528657]). This study follows several trials that are underway in China, including two Phase III studies in pancreatic and non-pancreatic NET that commenced after positive results from a Phase II study, and a Phase II study in BTC patients. In addition, a Phase I dose escalation part of this study in the U.S. was recently completed.

This proof-of-concept study is a multi-center, single-arm, open-label study to evaluate the efficacy and safety of sulfatinib as a monotherapy in (a) patients with advanced BTC that have progressed on standard first-line chemotherapy, and (b) in patients with advanced pancreatic NET. The primary and secondary endpoints include progression-free survival ("PFS") rate, objective response rate ("ORR"), disease control rate ("DCR"), duration of response ("DoR"), time to response, overall survival ("OS"), safety and tolerability. Additional details of the study may be found at clinicaltrials.gov, using identifier NCT02549937.

About Sulfatinib
Sulfatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptor ("VEGFR"), fibroblast growth factor receptor ("FGFR") and colony stimulating factor-1 receptor ("CSF-1R"), three key tyrosine kinase receptors involved in tumor angiogenesis and immune evasion. Inhibition of the VEGFR signaling pathway can act to stop angiogenesis, the growth of the vasculature around the tumor, and thereby starve the tumor of the nutrients and oxygen it needs to grow rapidly. Aberrant activation of the FGFR signaling pathway, which can be increased by anti-VEGFR therapy treatment, is shown to be associated with cancer progression by promoting tumor growth, angiogenesis and formation of the myeloid derived suppressor cells. Inhibition of the CSF-1R signaling pathway blocks the activation of tumor-associated macrophages, which are involved in suppressing immune responses against tumors. Its unique angio-immuno kinase profile supports sulfatinib as a potentially attractive candidate for exploration of possible combinations with checkpoint inhibitors against various cancers.

Sulfatinib is the first oncology candidate that we have taken through proof-of-concept in China and subsequently started clinical development in the U.S. We are currently conducting studies in six target patient populations on sulfatinib and retain all rights to sulfatinib worldwide.

About Sulfatinib Development in China
Sulfatinib is currently in development as a single agent for patients with NET, thyroid cancer and BTC in China.

Pancreatic NET: In March 2016, we initiated the SANET-p study, which is a randomized, double-blind, placebo-controlled, multi-center, Phase III pivotal registration trial to treat about 190 patients with low- or intermediate-grade, advanced pancreatic NET in China. The primary endpoint is PFS, with secondary endpoints including ORR, DCR, DoR, time to response, OS, safety and tolerability. Additional details of the SANET-p study may be found at clinicaltrials.gov, using identifier NCT02589821. We expect to complete enrollment in 2019 and present top-line results thereafter.

Extra-pancreatic NET: The SANET-ep study, which was initiated in December 2015, is similar to the SANET-p study and is targeted at treating about 270 patients with advanced extra-pancreatic NET in China. Additional details of the SANET-ep study may be found at clinicaltrials.gov, using identifier NCT02588170. We expect to complete enrollment in 2019 and present top-line results thereafter.

Thyroid cancer: In March 2016, we initiated Phase II in two target patient populations in China to evaluate the efficacy and safety of sulfatinib in patients with advanced medullary thyroid cancer and iodine-refractory differentiated thyroid cancer. Additional details of this study may be found at clinicaltrials.gov, using identifier NCT02614495.

BTC: In January 2017, we began a Phase II study in patients with BTC (also known as cholangiocarcinoma), a heterogeneous group of rare malignancies arising from the biliary tract epithelia. Gemzar is the currently approved first-line therapy for biliary tract cancer patients, with a total of approximately 18,000 new patients per year in the U.S. according to the National Cancer Institute, but median survival is less than 12 months for patients with unresectable or metastatic disease at diagnosis. As a result, we see a major unmet medical need for patients who have progressed when being treated with Gemzar, and sulfatinib may offer a new targeted treatment option in this tumor type. Additional details of this study may be found at clinicaltrials.gov, using identifier NCT02966821.
