Brief summary: This phase 1 clinical trial is intended to understand the safety and tolerability of a new anticancer drug in subjects with advanced solid tumors. The patients who qualify for the study will receive a once daily dose of the drug taken by mouth and will undergo several tests to measure the drug in the blood and to understand the safety, tolerability and any effect of the drug on the tumor. The antitumor effect of the drug is not known in human.

Detailed description: The study will be conducted in two parts. Part 1 is a dose escalation study in which subjects in each cohort will be given increasing doses of the study drug until a maximum tolerated dose (MTD) or maximum administered dose (MAD) is determined as the recommended phase 2 dose (RP2D). The drug will be administered as oral capsules once daily in 21 day cycles, with no interruption between cycles if no unacceptable treatment-related toxicity or tumor progression are observed.

After determining the RP2D, Part 2 of the study, which is a dose expansion study will begin in which subjects with advanced non-small cell lung cancer who developed acquired resistance to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI), erlotinib, gefitinib, afatinib (and others) or whose tumors carry an ALK translocation and are resistant to ALK inhibitor therapy, will be treated with DS-2248 at RP2D. The drug will be administered as oral capsules once daily in 21 day cycles, with no interruption between cycles if no unacceptable treatment-related toxicity or tumor progression are observed.
