A Study to Investigate ALE.P03 as Monotherapy in Adult Patients With Selected Advanced or Metastatic CLDN1+ Solid Tumors

Sponsored by Alentis Therapeutics AG

About this study

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.P03 monotherapy in adult patients with selected squamous solid tumors.

This Study has a Phase I ALE.P03 monotherapy dose escalation and recommended dose for expansion (RDE) study and a Phase II study of ALE.P03 as monotherapy at RP2D in adult patients with selected advanced or metastatic Claudin-1 positive (CLDN1+) cancers.
