CAR T cell treatment for metastatic triple-negative breast cancer

Project 4: Activity of CAR T cell Therapy for Patients with Metastatic TNBC

['FUNDING_OTHER'] · UNIV OF NORTH CAROLINA CHAPEL HILL · NIH-11181670

This gives people with metastatic triple-negative breast cancer a personalized treatment using their own T cells modified to target the B7‑H3 protein.

What this research studies

Doctors will collect a patient's own T cells, engineer them to recognize the B7‑H3 protein, and infuse those CAR‑T cells back into patients in a Phase I clinical infusion at UNC. The team is also developing dual CAR‑T cells that target both B7‑H3 and CSPG4 to reduce tumor escape and better cover diverse tumor cells. To address brain metastases, researchers will engineer CAR‑T cells to express CCR2b to improve trafficking across the blood‑brain barrier and will test immune‑modifying combinations that may boost activity. Lab and mouse studies will guide which engineered CAR designs and combinations move forward for patient use.

Who could benefit from this research

Good fit: Adults with metastatic triple‑negative breast cancer whose tumors express B7‑H3 and who can safely undergo T‑cell collection and infusion would be the ideal candidates.

Not a fit: People with early‑stage TNBC, tumors that do not express B7‑H3, or those who are too frail for cell collection or infusion may not benefit from this approach.

Why it matters

Potential benefit: If successful, this could provide a new targeted therapy that shrinks metastatic TNBC tumors and may reach brain metastases.

How similar studies have performed: CAR‑T therapies have transformed some blood cancers but have had limited success in solid tumors so far; B7‑H3 targeting shows encouraging preclinical results but clinical evidence is still preliminary.
