Study on T-DXd Combinations for HER2-positive Metastatic Breast Cancer

Sponsor: AstraZeneca

Sponsor score: 40

ClinicalTrials ID:NCT04538742

This clinical trial is exploring the safety and effectiveness of combining trastuzumab deruxtecan (T-DXd) with other cancer treatments for patients with HER2-positive metastatic breast cancer.

Patient Parameters

Program Overview

The DESTINY-Breast07 study aims to test how safe and effective trastuzumab deruxtecan (T-DXd) is when used with other cancer drugs in patients with HER2-positive metastatic breast cancer. The study will be conducted in two parts: the first part will determine the best dose, and the second part will expand the study to more patients using that dose. The study includes patients with advanced or metastatic HER2-positive breast cancer, including those with stable brain metastases.

Description

This study is designed to test the safety and effectiveness of T-DXd in combination with other cancer drugs. It will be conducted in two phases: a dose-finding phase to determine the best dose, and a dose-expansion phase to test this dose in more patients. The study focuses on patients with HER2-positive advanced or metastatic breast cancer, including those with stable brain metastases. In the first part, patients who have already received treatment for metastatic cancer will be enrolled. In the second part, patients who have not yet received treatment for advanced or metastatic cancer will be included.
