Trial Summary

What is the purpose of this trial?

This study is a 2-cohort, open-label, multicenter, phase 2 study of a short course of immunotherapy consisting of sequential decitabine followed by pembrolizumab administered prior to a standard neoadjuvant chemotherapy regimen for patients with locally advanced HER2-negative breast cancer. The primary efficacy objective is to determine if the immunotherapy increases the presence and percentage of tumor and/or stromal area of infiltrating lymphocytes prior to initiation of standard neoadjuvant chemotherapy. At enrollment, patients will be assigned to one of 2 cohorts based on hormone receptor status.* Cohort A - patients with HER2-negative, hormone receptor-negative breast cancer (defined as both ER and PgR with \< 10% positive staining on IHC) Note: before beginning standard neoadjuvant chemotherapy, patients in Cohort A may be reassigned to Cohort A2 to receive extended pembrolizumab as part of new standard neoadjuvant and postoperative adjuvant therapy.* Cohort B - patients with HER2-negative, hormone receptor-positive breast cancer (defined as either ER or PgR with ≥ 10% positive staining on IHC)

Treatment Details

Interventions

  • Carboplatin
  • Cyclophosphamide
  • Decitabine
  • Paclitaxel
  • Pembrolizumab
Trial Overview The study tests if a short course of decitabine followed by pembrolizumab before standard chemo increases immune cells in tumors in patients with advanced HER2-negative breast cancer. It's divided into two groups based on hormone receptor status: one potentially receiving extended pembrolizumab treatment.
