Disitamab Vedotin for Breast Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the safety and effectiveness of disitamab vedotin, a new treatment for people with advanced, hard-to-treat breast cancer that has spread throughout the body. Participants will receive the treatment through an IV drip every two weeks to evaluate its efficacy and safety. This trial suits those with breast cancer that has spread, tumors with a marker called HER2, and who have already tried other treatments for their advanced cancer. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.
Do I have to stop taking my current medications to join the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, you must not have received any systemic anticancer treatment or radiotherapy within 2 weeks before starting the study treatment, and you should have recovered from any side effects of previous therapies.
Is there any evidence suggesting that disitamab vedotin is likely to be safe for humans?
Previous studies have shown disitamab vedotin to be safe for treating breast cancer with varying levels of HER2, a protein present in some tumors. Research indicates no major safety concerns for patients with HER2-positive and HER2-low breast cancer. While some side effects occur, they are generally mild and manageable.
Common side effects include nausea and tiredness, which many patients experience. Standard care can usually manage these side effects. It's important to note that individual reactions vary, so experiences can differ.
Overall, disitamab vedotin appears well-tolerated in patients with advanced breast cancer. Prospective trial participants should discuss any concerns with their healthcare provider.12345Why do researchers think this study treatment might be promising for breast cancer?
Disitamab vedotin is unique because it targets HER2, a protein that plays a role in the growth of some breast cancers, with a precision-focused approach. Unlike standard treatments like trastuzumab or pertuzumab, which also target HER2, disitamab vedotin is an antibody-drug conjugate, meaning it links a potent chemotherapy drug directly to an antibody that binds to cancer cells. This allows for direct delivery of the drug to cancer cells, potentially sparing healthy cells and reducing side effects. Researchers are excited because this targeted delivery could enhance effectiveness and improve the quality of life for patients with HER2-positive, HER2-low, or HER2-ultra-low breast cancer.
What evidence suggests that disitamab vedotin might be an effective treatment for advanced breast cancer?
Research has shown that disitamab vedotin holds promise for treating advanced breast cancer, particularly in patients with HER2-positive and HER2-low tumors. In earlier studies, about one-third of patients experienced tumor shrinkage, with a 34.40% objective response rate. Additionally, 81.97% of patients achieved disease control, meaning their cancer stopped growing temporarily. This trial will evaluate disitamab vedotin monotherapy across different cohorts, including those with HER2-positive, HER2-low, and hormone receptor-positive or negative breast cancer. This treatment has benefited both hormone receptor-positive and hormone receptor-negative patients, indicating its potential to help a wide range of individuals. Overall, disitamab vedotin appears effective and is considered a promising option for those with difficult-to-treat, advanced breast cancer.46789

Are You a Good Fit for This Trial?
This trial is for adults with advanced breast cancer that has spread, expresses HER2, and who have already tried other treatments like trastuzumab, pertuzumab, a taxane, or T-DXd. They should not have had more than three prior systemic cytotoxic therapies. The study excludes those whose tumors don't meet specific HER2 and hormone receptor status criteria.Inclusion Criteria
