Brief summary

This is a multi-center, open-label study to investigate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary activity of REC-1245 administered orally on a once daily (QD) schedule in participants with unresectable, locally advanced, or metastatic solid tumors.

Detailed description

The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of REC-1245 for the treatment of participants with unresectable locally advanced or metastatic solid tumors. Participants will receive treatment with REC-1245 for up to 2 years.
