Phase

PHASE2

Detailed Description:

This is a phase 2 open label study of neoadjuvant trastuzumab deruxtecan plus durvalumab for patients with stage III, HER2-positive or HER2-low inflammatory breast cancer (IBC), who have not received prior therapy for ipsilateral breast cancer. Participants will be enrolled into one of two study treatment groups: HER2 positive IBC (Cohort 1) or HER2 low IBC (Cohort 2). Research procedures including screening for eligibility, clinic visits for treatment, tumor biopsies, and blood tests. The U.S. Food and Drug Administration (FDA) has not approved Durvalamab or Trastuzumab deruxtecan for inflammatory breast cancer, but both have been approved for other uses. Participation in this study is expected to last about 22 months. It is expected that about 63 people will take part in this research study. The pharmaceutical company, AstraZeneca, is supporting this research study by providing the study drugs and funding.

    Exclusion Criteria

The use of the inactivated seasonal influenza vaccine is allowed.
      • * Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
      • * Use of potent inhibitors or inducers or substrates of CYP3A4 or substrates of CYP2C9 or CYP2D6 within 2 weeks before the first dose of study treatment (3 weeks for St John's Wort)
