Testing Experimental Anti-cancer Drug SLC-391 with an Approved Immunotherapy Drug, Pembrolizumab, for Advanced Lung Cancers
Sponsor:

SignalChem Lifesciences Corporation

Brief Summary:

SLC-391 is a novel, potent and specific small molecule inhibitor of receptor tyrosine kinase AXL with desirable potency and pharmaceutical properties. The study is being done to evaluate the safety and pharmacokinetic (PK) profile of SLC-391 in combination with pembrolizumab in participants with non-small cell lung cancer (NSCLC). Each treatment cycle lasts 21 days. Participants will swallow SLC-391 pills two times every day. Participants will get pembrolizumab intravenously (IV) from the study site staff on the first day of every cycle. This study has 2 parts. The first part will determine the recommended dose of SLC-391 in combination with pembrolizumab. The second part wants to find out if the combination of SLC-391 and pembrolizumab can help stop NSCLC tumours from growing or spreading.

                        • * Females who are pregnant or nursing. Note: SLC reserves the right to deny any subject enrollment based upon potential safety concern(s) or factors that could confound the study results.
                        • Note: The Investigator or licensed, medically qualified Sub-Investigator must review and confirm eligibility prior to the first dose of study drug(s).
