| NCT07361562 | A Study of a Selective ERBB2 Inhibitor (CGT4255), in Patients With Advanced Solid Tumors | PHASE1 | RECRUITING | 100 | — | — | Dec 30, 2025 | Nov 1, 2028 | Feb 27, 2026 | 6 | United States |
1\. Incidence and grade of Adverse Events (AEs) and Serious Adverse Events (SAEs) and AEs leading to dose modifications and dose limiting toxicities (DLTs) to determine the maximum tolerated dose (MTD) or the maximum evaluated dose (MED) in participants with ERBB2-altered advanced solid tumors
Overall Response Rate (ORR), determined by confirmed CR + PR of all lesions (intracranial and extracranial), based on Investigator assessment using the whole-body RECIST v1.1 in participants with ERBB2-mutated NSCLC with Brain Metastases (BM) and in participants with ERBB2-mutated or HER2-positive breast cancer with BM ± leptomeningeal disease (LMD)
