A Study of LY4101174 in Participants With Recurrent, Advanced or Metastatic Solid Tumors

Summary

The purpose of this study is to find out whether the study drug, LY4101174, is safe, tolerable and effective in participants with select advanced or metastatic solid tumors. The study is conducted in two parts - phase Ia (dose-escalation, dose-optimization) and phase Ib (dose-expansion). The study will last up to approximately 4 years.
