Adjuvant Chemoradiation and Biomarkers of Response in High-risk Breast Cancer

A Study of Adjuvant Chemoradiation and Biomarkers of Response in High-risk Breast Cancer

Adjuvant Chemoradiation and Biomarkers of Response in High-risk Breast Cancer (NCT05288777) is a Phase 2 / Phase 3 interventional studying Breast Cancer and Breast Cancer Stage I, sponsored by University of Virginia. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The goal of this study is to evaluate the safety and effectiveness of adjuvant chemoradiation therapy in high-risk breast cancer patients who had received neoadjuvant chemotherapy before their lumpectomy and/or mastectomy and were found to have residual disease. As well as examine the effects of this treatment combination on the immune system.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Breast Cancer and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 45 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
