Updated on 28 July 2022


The purpose of this first in human (FIH) trial is to characterize the safety and tolerability of the SHP2 inhibitor TNO155 alone and in combination with EGF816 (nazartinib) and identify a recommended dose for future studies in adult patients with advanced solid tumors in selected indications.


This study has been designed as a Phase I, open-label, dose finding study with a dose escalation part and a dose expansion part in adult patients with selected advanced solid tumors. The study treatment, TNO155 alone or in combination with EGF816 (nazartinib), will be taken until the patient experiences unacceptable toxicity, progressive disease and/or treatment is discontinued at the discretion of the investigator or the patient or due to withdrawal of consent. Some patients will be participating in a food effect investigation as an exploratory objective.
