A Study of a Selective ERBB2 Inhibitor (CGT4255), in Patients With Advanced Solid Tumors
Sponsored by Cogent Biosciences, Inc.
About this study
This is an open-label, phase 1/1b study evaluating the safety, tolerability, pharmacokinetic (what the body does to the drug), pharmacodynamic (what the drug does to the body), and antitumor activity of CGT4255 in adult participants with advanced solid tumors with ERBB2 alterations or HER2 overexpression.

Who can participate
Inclusion criteria
- ✓1. Have histologically confirmed diagnosis of:

- ✓2. Part B: Locally advanced, metastatic, and/or unresectable NSCLC with documented ERBB2 mutation in blood and/or tumor
- ✓3. Part C: Locally advanced, metastatic and/or unresectable breast cancer with documented ERBB2 mutation in blood and/or tumor or HER overexpression in tumor

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.
Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
