Brief Summary:

This research trial is studying a combination of neoadjuvant radiotherapy (RT), immunotherapy (pembrolizumab) and chemotherapy for lymph node-positive, triple negative (TN) or hormone receptor positive/HER2-negative breast cancer.

The names of the study interventions involved in this study are:

  • Radiation Therapy (RT)
  • Immunotherapy: Pembrolizumab (MK-3475)
  • Chemotherapies:

    • Paclitaxel
    • Doxorubicin (also called Adriamycin)
    • Cyclophosphamide
    • Carboplatin (optional, and in TN only)
    • Capecitabine (optional, and in TN only)

Condition or disease Intervention/treatment Phase
Triple Negative Breast Cancer Hormone Receptor Positive (HR+), HER2-negative Breast Cancer Biopsy-proven, Positive Lymph Node(s) Radiation: Radiation Therapy Boost Drug: Pembrolizumab Drug: Paclitaxel Drug: Carboplatin Drug: Cyclophosphamide Drug: Doxorubicin Drug: Capecitabine Phase 2

Detailed Description:

The main purpose of this study is to find out what is the best dose of preoperative RT when combined with pembrolizumab and chemotherapy. The study will assess if combining the RT with the immunotherapy agent, pembrolizumab, will increase the ability of the immune system to destroy cancer cells.

The research study procedures include: screening for eligibility and study treatment, including evaluations and follow-up visits.

The study aims to assess the effectiveness of pembrolizumab (study drug) with or without RT directed to the breast tumor. Participants will then undergo neoadjuvant chemotherapy with pembrolizumab, followed by treatment that can consist of one or more of the following:

  • Pembrolizumab (optional, per MD discretion)
  • Standard of Care Treatment

    • Breast surgery (lumpectomy or mastectomy) and axillary surgery
    • Adjuvant radiation to the entire breast or chest wall, plus or minus the lymph nodes after surgery
    • Adjuvant chemotherapy (optional Capecitabine for TNBC patients)
    • Hormone therapy

Participants will be randomized to 1 of 3 groups. Neither the participant not the research doctor will choose the group that the participant is assigned to. However, the participant will be notified of the group prior to the start of study treatment. Participants will receive study treatment for up to 13 months. Participants will be followed for 2 years after the end of the study treatment.

It is expected that a total of 120 people will be participating in total.

This research study is a randomized, phase II study. The U.S. Food and Drug Administration (FDA) has not approved pembrolizumab for your specific disease, but it has been approved for other uses. The U.S. Food and Drug Administration (FDA) has approved the chemotherapies being used in this study (Paclitaxel, Doxorubicin, Cyclophosphamide, Carboplatin, Capecitabine).

    RCB is a measure of residual cancer burden in the breast and regional lymph nodes at the time of definitive surgery following completion of neoadjuvant systemic therapy.

  2. Pathologic response rate [ Time Frame: 24 Weeks ]
    Pathologic response rate is measured by the presence or absence of residual cancer cells in all sampled regional lymph nodes. RCB measures residual disease in the breast and lymph nodes at the time of definitive surgery. CD3+/CD8+ T cell Breast Immunoscore greater than 75% versus patients with Post-treatment CD3+/CD8+ T cell Breast Immunoscore less than or equal to 75%.

  3. Percent change in pre- versus post-treatment intra-tumoral TILs [ Time Frame: 24 Weeks ]
    Intra-tumoral, peri-tumoral and stromal CD3+, CD8+, and CD3+CD8+ T cell densities will be measured using pan-cytokeratin staining and multiplexed QIF

    TIL counts by H&E in pre-treatment versus post-RT boost tumor biopsy specimens in each RT dose and breast cancer subtype cohort.

    H&E will be performed according to Salgado Criteria [1].


  7. Changes in PD-L1 expression [ Time Frame: 24 Weeks ]

    To quantify changes in PD-L1 expression levels after treatment with Pembro + no, low or high RT boost (at the time of the time of interval biopsy).

    QIF for PD-L1 will be performed in pre- and post-treatment FFPE tumor biopsy samples.


  8. Changes in intratumoral, per-tumoral, and stromal CD4+Foxp3+ T regulatory cell densities [ Time Frame: 24 Weeks ]

    To quantify changes in intratumoral, per-tumoral, and stromal CD4+Foxp3+ T regulatory cell densities in response to treatment with preoperative Pembro + no, low, or high dose RT boost (at the time of interval biopsy).

    QIF for CD4 and Foxp3 will be performed in pre- and post-treatment FFPE tumor biopsy samples. Pan-cytokeratin staining will be used to identify tumor regions

    iDFS is defined as time from completion of surgery to the first occurrence of the following events: invasive ipsilateral, local, regional, or distant recurrence, or death due to breast cancer.

  11. Event-free survival (EFS) [ Time Frame: time from completion of surgery to the first occurrence of the following events: progression of disease (precluding surgery), recurrence (local or distant), or death due to any cause up to 31 months. ]
    EFS is defined as the time from the initiation of the study treatment to any of the following events: progression of disease (precluding surgery), recurrence (local or distant), or death due to any cause.

  12. Symptomatic Improvement [ Time Frame: baseline to 21 Weeks ]
    PROMIS Global Health Measure Quality of life (e.g., global, physical, mental, and social health) outcomes will be measured by two PROMIS (Patient-Reported Outcomes Measurement Information System) short forms consisting of 4 questions total. This instrument has demonstrated content-validity, cross-sectional validity, and responsiveness to change in numerous publications[93].

  13. Change in Symptoms and Satisfaction with Treatment [ Time Frame: baseline to Week 3 ]
    (Breast-Q), four domains will be evaluated both before and after surgery: satisfaction with breasts, psychosocial, sexual, and physical well-being. Scores for each domain range from 0-100, with higher scores indicative of better quality of life

  14. Change in Symptoms and Satisfaction with Treatment [ Time Frame: baseline to week 21 ]
    (Breast-Q), four domains will be evaluated both before and after surgery: satisfaction with breasts, psychosocial, sexual, and physical well-being. Scores for each domain range from 0-100, with higher scores indicative of better quality of life

  15. Change Patient Reported Outcomes [ Time Frame: 3 years ]
    PRO-CTCAE will evaluate symptom burden in the previous week using a Likert scale to assess presence/absence, frequency, severity and/or interference for different symptoms. Each symptom will be presented descriptively, using summary statistics and graphical representations across time points.

  16. Financial Burden [ Time Frame: 3 to 6 wks after last dose in the Neoadjuvant Period up to 8 Months ]
    Recently coined term used to describe the potential financial burden patients experience while receiving medical care. Two questions were adapted from the National Health Interview Survey[95] and a survey administered to caregivers of participants of the Cancer Car Outcomes Research and Surveillance (CanCORS) study[96] to assess financial burden and impact on employment-related metrics (e.g., sick leave, unpaid time off work). Financial burden will be assessed at the post-surgery visit.

  17. Trial Satisfaction [ Time Frame: 3 to 6 wks after last dose in the Neoadjuvant Period up to 8 Months ]
    The Was It Worth It (WIWI) instrument, also called the "Trial Satisfaction" survey, was developed to investigate the patient experience on clinical trials. Multiple cooperative group studies have utilized this instrument at the completion of treatment to measure patient satisfaction relating to clinical trial enrollment, although formal validity and reliability data is not yet available[
