What this trial studies

This study consists of two parts aimed at evaluating the safety and effectiveness of zongertinib in adults with advanced solid tumors that have alterations in the HER2 gene. The first part focuses on determining the maximum tolerated dose of zongertinib, while the second part assesses its ability to shrink tumors in patients with non-small cell lung cancer harboring specific HER2 mutations. Participants will take zongertinib orally once or twice daily, and their health and tumor response will be closely monitored throughout the study. The study aims to provide insights into the potential of zongertinib as a treatment option for these patients.

Who should consider this trial

Good fit: Ideal candidates include adults with advanced, unresectable, or metastatic solid tumors that have confirmed HER2 gene changes.

Not a fit: Patients with hematologic malignancies or those who do not have measurable lesions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new treatment option for patients with advanced cancers that have HER2 gene alterations.

How similar studies have performed: Other studies targeting HER2 alterations in cancer have shown promising results, indicating potential for success with this approach.
