Testing a Vaccine for Preventing or Treating Triple-Negative Breast Cancer

About the Study

Researchers are studying the affects of this breast cancer vaccine on the immune system in the following groups:

• Prevention arm:
  • people with an inherited mutation in BRCA1, BRCA2, or PALB2, who have not been diagnosed with cancer, and who are planning to undergo a risk-reducing mastectomy.
• Treatment arms:
  • people diagnosed with stage 2 or stage 3 triple-negative breast cancer who have completed treatment and are considered at high risk for recurrence.
  • people diagnosed with stage 2 or stage 3 triple-negative breast cancer who have completed chemotherapy and radiation and are currently receiving Keytruda (pembrolizumab).

This listing is for people who have never been diagnosed with breast cancer. If you have been diagnosed with triple-negative breast  cancer and are interested in joining the treatment portion of the study, see our study listing here.
