Study Endpoints
Primary Endpoints
Number of Participants With Dose Limiting Toxicities (DLTs)
Up to 28 days from the first dose

A DLT is defined as an adverse event that is likely related to the study medication or combination, and fulfils any one of the following criteria, graded according to the NCI-CTCAE (National Cancer Institute-Common Terminology Criteria for Adverse Events) version 5.0: * Grade 3 thrombocytopenia associated with clinically significant bleeding and requiring platelet transfusion or Grade 4 thrombocytopenia of any duration. * Grade ≥3 febrile neutropenia * Grade ≥3 anemia requiring a blood transfusion * Other Grade ≥4 toxicities, excluding few nonhematologic Toxicities * Any other significant toxicity deemed by the investigatory to be dose-limiting, such as: any toxicity that is possibly related to the study medication that requires the withdrawal of the participant from the study during 28-day DLT observation period), persistent Grade \>2 toxicities causing a delay of LY3475070 study treatment \>14 days during the 28-day DLT observation period.
