Dato-DXd for Breast Cancer
(TB06 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called Dato-DXd for individuals with a specific type of advanced breast cancer. The goal is to evaluate the drug's effectiveness and safety for patients with breast cancer that has spread, is hormone receptor-positive, and lacks the HER2 protein. Participants should have previously tried hormone therapies without benefit and should not have undergone chemotherapy in the metastatic setting. The trial targets those whose daily lives are impacted by breast cancer, offering a new treatment option before considering chemotherapy. As a Phase 3 trial, this study serves as the final step before FDA approval, providing participants access to a potentially groundbreaking treatment.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, certain medications like chloroquine/hydroxychloroquine require a washout period (time without taking the medication) of more than 14 days before starting the study. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that Dato-DXd is likely to be safe for humans?
Research shows that Dato-DXd is generally well-tolerated by patients. Studies have found it safe for people with certain types of breast cancer. While side effects are common, they are usually mild, and serious side effects occur less frequently. Most patients handle the treatment without major problems. Prospective trial participants may find this information reassuring regarding its safety.12345
Why do researchers think this study treatment might be promising?
Unlike the standard breast cancer treatments, which often include hormone therapies, chemotherapy, and targeted therapies like Herceptin (trastuzumab), Dato-DXd is unique because it combines a monoclonal antibody with a chemotherapy agent, creating an antibody-drug conjugate. This innovative approach allows Dato-DXd to specifically target cancer cells, delivering the chemotherapy directly to them, which may reduce damage to healthy cells. Researchers are excited about Dato-DXd because this targeted delivery could lead to fewer side effects and improved outcomes for patients, making it a promising option in the fight against breast cancer.
What evidence suggests that Dato-DXd might be an effective treatment for breast cancer?
Research has shown that Dato-DXd yields promising results for certain types of breast cancer. In one study, Dato-DXd helped patients live 37% longer without their cancer worsening, a measure known as progression-free survival. Another study found it reduced the chance of the disease worsening by 43% and lowered the risk of death in patients with triple-negative breast cancer. For patients with HR-positive, HER2-negative breast cancer, Dato-DXd also significantly improved progression-free survival. These findings suggest that Dato-DXd might effectively treat breast cancer by slowing its growth and potentially extending patients' lives. All participants in this trial will receive Dato-DXd to further evaluate its effectiveness and safety.23567
Are You a Good Fit for This Trial?
This trial is for individuals with inoperable or metastatic hormone receptor-positive, HER2 IHC 0 breast cancer.
