Pembro/IORT Trial Summary

This trial is testing a new cancer drug, pembrolizumab, to see if it is effective against triple negative breast cancer. The trial will assess the response to the drug in the primary tumor, normal breast tissue, and in circulating lymphocytes and serum exosomes.

Who is the study for?
This trial is for women over 21 with early-stage triple negative breast cancer (TNBC) that's ≤3cm and hasn't spread. They must have good organ function, no prior cancer treatments in the last 6 months, not be pregnant or breastfeeding, and agree to use contraception. Excluded are those with larger tumors, active infections or autoimmune diseases requiring recent treatment, certain other cancers within 5 years, psychiatric/substance issues affecting participation, previous immunotherapy or live vaccines recently.Check my eligibility
What is being tested?
The study tests Pembrolizumab's effects on TNBC before surgery by measuring changes in tumor-infiltrating lymphocytes. Participants receive two doses of Pembrolizumab followed by a lumpectomy where Intraoperative radiation therapy (IORT) is also applied. The goal is to see how the drug alters the tumor environment and immune response.See study design
What are the potential side effects?
Pembrolizumab may cause immune-related side effects like inflammation in various organs including lungs (pneumonitis), liver problems, skin reactions, hormone gland issues (like thyroid disorders), infusion reactions; fatigue; digestive troubles; potential for infection increase.

Pembro/IORT Trial Design

1Treatment groups
Experimental Treatment
Group I: Single Arm open labelExperimental Treatment2 Interventions
Participants receive 'Merck 3475 Pembrolizumab' by vein one to two times before Intraoperative radiation therapy (IORT). The Intrabeam® Photon Radiosurgery System is a miniature electron beam-driven X-ray source which provides a point source of low energy X-rays (50 kV maximum) at the tip of a 3.2 mm diameter tube. The radiation source can be inserted into the area of interest immediately after excision of the tumor and switched on for 20-35 minutes to provide intraoperative radiotherapy accurately targeted to the tissues that are at the highest risk of local recurrence. The dosimetric characteristics and early clinical applications of this device have been well studied and this is the device which was utilized in the international TARGIT trial.
