Pre-op Pembro + Radiation Therapy in Breast Cancer (P-RAD)

P-RAD: A Randomized Study of Preoperative Chemotherapy, Pembrolizumab and No, Low or High Dose RADiation in Node-Positive, HER2-Negative Breast Cancer

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)

Study Overview

• Status: Recruiting
• Conditions: Triple Negative Breast Cancer; Hormone Receptor Positive (HR+), HER2-negative Breast Cancer; Biopsy-proven, Positive Lymph Node(s)
• Intervention / Treatment: Drug: Pembrolizumab; Drug: Paclitaxel; Drug: Carboplatin; Drug: Cyclophosphamide; Drug: Doxorubicin; Drug: Capecitabine; Radiation: Radiation Therapy Boost

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).

Financial Burden	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.	3 to 6 wks after last dose in the Neoadjuvant Period up to 8 Months
Trial Satisfaction	The Was It Worth It (WIWI) instrument, also called the "Trial Satisfaction" survey, was developed to investigate the patient experience on clinical trials.
