Trastuzumab Deruxtecan for Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method of delivering the cancer drug Trastuzumab Deruxtecan (an antibody-drug conjugate) to individuals with advanced or metastatic breast cancer that is either HER2-positive or HER2-low. Researchers aim to determine the optimal dose and assess its safety and effectiveness when administered as a subcutaneous injection. Suitable candidates have advanced or metastatic breast cancer that has not responded well to previous treatments, such as chemotherapy. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, providing participants the opportunity to be among the first to receive this new approach.
Do I need to stop my current medications to join the trial?
The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that Trastuzumab Deruxtecan is likely to be safe for humans?
Research has shown that trastuzumab deruxtecan (T-DXd) raised some safety concerns in past studies. About 13% of patients developed interstitial lung disease (ILD), where the lungs become inflamed and scarred. Although serious, fatal cases were rare, occurring in less than 1% of patients. Additionally, about 7.1% of patients stopped treatment due to side effects. Severe cases of neutropenia, a dangerously low level of a type of white blood cell, have also been reported.
While these side effects are important to consider, the treatment has been thoroughly studied and is FDA-approved for certain conditions. This approval indicates it has passed strict safety checks for those uses. However, this trial is testing a new method of administering the drug, so safety remains under close observation.12345Why do researchers think this study treatment might be promising?
Trastuzumab Deruxtecan is unique because it combines a targeted therapy with a chemotherapy agent, creating a powerful treatment option for certain cancers. Unlike traditional chemotherapy, which attacks all rapidly dividing cells, this drug specifically targets HER2 proteins on cancer cells, delivering the chemotherapy directly to the tumor. This targeted approach not only increases the effectiveness of the treatment but also reduces damage to healthy cells, potentially leading to fewer side effects. Researchers are particularly excited about its subcutaneous delivery method, which could provide a more convenient and less invasive alternative to intravenous administration.
What evidence suggests that Trastuzumab Deruxtecan might be an effective treatment for metastatic solid tumors?
Research has shown that trastuzumab deruxtecan yields promising results for treating certain cancers. In earlier studies, this treatment reduced the risk of cancer recurrence or death by 53% compared to T-DM1. Patients using trastuzumab deruxtecan in real-world settings experienced about 5 months without disease progression and had an overall survival of about 15 months. However, there is a significant risk of side effects, such as interstitial lung disease (ILD), which affected about 13% of patients in studies. These findings suggest that trastuzumab deruxtecan could effectively treat advanced solid tumors, though side effects require careful management. Participants in this trial will receive trastuzumab deruxtecan either at escalating doses to determine the recommended dose for expansion or at the recommended dose for expansion in the dose expansion phase.13678
Are You a Good Fit for This Trial?
This trial is for individuals with metastatic solid tumors that have come back after previous treatment. Specific details about who can join are not provided, but typically participants must meet certain health standards and may need to have a particular type of tumor marker.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Trastuzumab Deruxtecan
Trial Overview
The study is testing Trastuzumab Deruxtecan (T-DXd) given under the skin with an enzyme called hyaluronidase. It's looking at how safe it is, how well people tolerate it, what happens to it in the body (pharmacokinetics), and if it works against cancer.
