Clinical trial for Anatomic Stage II Breast Cancer AJCC v8

Official title Pembrolizumab vs. Observation in People With Triple-negative Breast Cancer Who Had a Pathologic Complete Response After Chemotherapy Plus Pembrolizumab

ClinicalTrials.gov ID: NCT05812807

What this study is testing

What is Pembrolizumab?

This is an investigational medicine being studied to see if it helps prevent early-stage triple-negative breast cancer from coming back after surgery. It is designed to help the body's immune system attack cancer cells.

Also referred to as Keytruda.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This study aims to find out if patients can safely stop taking pembrolizumab after surgery if their cancer has completely disappeared, compared to continuing the drug for 27 weeks.
Who it's for
People with early-stage triple-negative breast cancer who had no signs of cancer left after chemotherapy and surgery.
What's involved
Participants will either continue taking pembrolizumab (an immune system booster) or stop treatment and be monitored closely by doctors.
Time commitment
The study involves regular check-ups and tests to monitor health for up to 27 weeks after surgery.
  • Phase 3: a large, late-stage study
  • Time commitment: about 27 weeks
  • Which group you join is decided by chance.

  • Axillary dissection without sentinel node evaluation is permitted as the initial or sole axillary evaluation after preoperative therapy
  • If breast-conserving surgery was performed but patient will not be receiving breast radiation, the patient is not eligible
