A Study of TAS3351 in NSCLC Patients With EGFRmt

Phase 1
Terminated
Conditions
Non-Small Cell Lung Cancer
Interventions
Drug: TAS3351 oral administration
Registration Number
NCT05765734
Lead Sponsor
Taiho Oncology, Inc.
Brief Summary

This is a first-in-human, open label, Phase 1/2 study to investigate the safety and efficacy of TAS3351 in patients with advanced or metastatic non-small cell lung cancer (NSCLC) harboring an acquired C797S epidermal growth factor receptor (EGFR) mutation.

Detailed Description

This study will be conducted in 3 parts (i.e. dose escalation, dose expansion, and a phase 2 portion). The dose escalation part will investigate the safety and determine the recommended phase 2 dose and the recommended dosing regimen of TAS3351 administered orally. The dose expansion part will explore the efficacy of TAS3351 in NSCLC patients with C797S EGFR mutations. The phase 2 part will assess the efficacy of TAS3351 in NSCLC patients with C797S EGFR mutations.
