A Study to Investigate ALE.P02 as Monotherapy in Adult Patients With Selected CLDN1+ Solid Tumors

Summary

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic, pharmacodynamic, preliminary anti-tumor activity, and to determine the recommended Phase II dose (RP2D) of the ALE.P02 monotherapy in adult patients with selected squamous solid tumors.
