SignalChem Initiates Phase 1 Clinical Trial for SLC-391 in Subjects with Solid Tumours

VANCOUVER, BRITISH COLUMBIA–(November 7, 2019) – SignalChem Lifesciences Corp. (“SLC”), a clinical stage biotech company, has dosed its first patient in a Phase 1 clinical trial studying the safety and tolerability of SLC-391, a potent and selective AXL inhibitor, at Princess Margaret Cancer Centre in Toronto, Ontario. The study marks a significant clinical milestone for SLC. By taking a targeted therapy approach, the Company aims to develop SLC-391 for the treatment of various forms of cancer.

AXL is a putative driver of diverse cellular processes that are critical for the development, growth, and spread of tumours, including proliferation, invasiveness and migration, epithelial-mesenchymal transition (EMT), stemness, angiogenesis, and immune modulation. It has also been associated with both intrinsic and acquired resistance to chemotherapeutic drugs (e.g, paclitaxel and cisplatin) and molecularly targeted therapies (e.g, erlotinib and gefitinib). AXL has emerged as an increasingly attractive target for anticancer therapies in recent years. SLC-391 is a novel, potent and specific small molecule AXL inhibitor. It has demonstrated antiproliferative activity against different tumour cell lines in vitro and established efficacy in different animal models including non-small cell lung carcinoma (NSCLC), chronic myeloid leukemia (CML) and acute myeloid leukemia (AML) models. It can also work with other approved targeted therapies synergistically in different animal models to potentiate anti-tumour activity.

“Targeting receptor tyrosine kinase AXL represents a promising new approach for treating cancers, especially for cancer metastases, cancer stem cell survival, and acquired resistance to chemotherapies and other targeted therapeutics. SLC has developed its potent, selective and orally bioavailable Axl inhibitor SLC-391 to meet these medical needs. This novel therapy could provide a meaningful and beneficial alternative to cancer patients”, commented by Mr. Jun Yan, the CEO and founder of SLC.

About the Phase 1 Trial

The Phase 1 trial is an open-label, dose-escalation, and dose-expansion study of the safety and pharmacokinetics of the AXL Inhibitor SLC-391 administered orally to subjects with solid tumours. The study is being conducted with sites located at The Ottawa Hospital Cancer Centre in Ottawa, Ontario, Princess Margaret Cancer Centre in Toronto, Ontario, and Juravinski Cancer Centre in Hamilton, Ontario. The primary objectives are to evaluate the safety of oral SLC-391 and to determine the maximum tolerated dose (MTD) of SLC-391. The secondary objectives are to characterize the pharmacokinetic (PK) profile of SLC-391, to determine the recommended phase 2 dose (RP2D) of SLC-391 and to preliminarily evaluate the efficacy of SLC-391.
