Summary

This is a phase 1/1b, open-label, multicenter study consisting of sequential parts designed to evaluate the safety, tolerability, and effects pharmacokinetic (PK) profile, and antitumor activity of RGT-490, an investigational oral therapy, in adults with locally advanced or metastatic solid tumors including breast cancer.
