Topic: Now Enrolling: DESTINY-Breast04 Trial for low HER2 bc

Forum: Stage IV/Metastatic Breast Cancer ONLY —

Please respect that this forum is for members with stage IV/metastatic breast cancer only. There is a separate forum for caregivers and friends: Caring for Someone with Stage 4 or Mets.

Metastatic breast cancer (MBC; also called stage IV) is breast cancer that has spread to other parts of the body, most commonly the bones, liver, brain, or lungs. Metastatic breast cancer can be treated but not cured. Metastatic disease is NOT hopeless. There are a wide variety of treatment options for metastatic breast cancer, and new medicines are being tested every day. More and more people are living life to the fullest while being treated for metastatic breast cancer.

Note: Please contact your doctor for any specific concerns about symptoms you are experiencing or your course of treatment.

Learn more about living with MBC.

The DESTINY-Breast04 trial is a phase III trial for people diagnosed with metastatic breast cancer with low HER2 levels or other stages of breast cancer with low HER2 levels that can't be removed with surgery. For the purposes of this study, breast cancer with low HER2 levels means the cancer has a score of 2+ or 1+ on an immunohistochemistry (IHC) HER2 test or a negative fluorescence in situ hybridization (FISH) HER2 test. Breast cancer with these IHC or FISH scores would usually be considered HER2-negative breast cancer. Still, earlier studies have shown that the medicine being studied may help treat breast cancers with extremely low HER2 levels, which is why this larger study is being done.

The cancer also must have been previously treated with one or two chemotherapy regimens for people to be eligible for this study.

The trial is looking to see if the medicine fam-trastuzumab-deruxtecan-nxki offers more benefits than your doctor's choice of four chemotherapy medicines:

  • Xeloda (capecitabine)
  • Halaven (chemical name: eribulin)
  • Gemzar (chemical name: gemcitabine)
  • Taxol (chemical name: paclitaxel)
  • Abraxane (chemical name: albumin-bound or nab-paclitaxel)
