Part 1 of the study is open to all solid tumors. Part 2 of the study will evaluate the safety, tolerability and preliminary efficacy of DSP107, administered either as monotherapy or in combination with atezolizumab. The study will enrol subjects with NSCLC that is wildtype for actionable oncogenic driver mutations, and who have progressed following first line treatment with PD-1 or PD-L1 targeting agents having previously achieved a best response of stable disease or better measured after 12 weeks.




I/II - A combination of phases: (1) Research Studies that focus on the safety of a drug. The goal is to determine the drug's most frequent and serious adverse events and, often, how the drug is broken down and excreted by the body. These studies usually involve a small number of participants; and (2) Research Studies that gather preliminary data on whether a drug works in people who have a certain condition/disease (that is, the drug's effectiveness). For example, participants receiving the drug may be compared to similar participants receiving a different treatment, usually an inactive substance (called a placebo) or a different drug. Safety continues to be evaluated, and short-term adverse events are studied.
