Using PET scans to guide treatment for triple negative breast cancer

A Pilot Study of Neoadjuvant Response-Adapted Chemotherapy With Pembrolizumab in Patients With Stage 2 and 3 Triple Negative Breast Cancer to Determine Early PET and Biomarker Dynamics

Phase 2 Interventional Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins · NCT06245889

This study tests if using PET scans can help doctors tailor treatment for people with stage 2 and 3 triple negative breast cancer to improve their chances of a successful surgery.

What this trial studies

This clinical trial focuses on patients with stage 2 and 3 triple negative breast cancer (TNBC) who will receive a combination of paclitaxel, carboplatin, and pembrolizumab as neoadjuvant therapy. Participants will undergo PET scans and MRIs at various stages to assess their response to treatment. Those achieving a complete clinical response will proceed to surgery, while those with residual disease will receive additional neoadjuvant therapy before surgery. The study aims to optimize treatment based on individual responses to therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with stage II-III triple negative breast cancer.

Not a fit: Patients with metastatic disease, inflammatory breast cancer, or those who have previously received certain treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective treatment strategies for patients with triple negative breast cancer.

How similar studies have performed: Other studies have shown promise in using imaging to adapt treatment strategies, making this approach both innovative and supported by prior research.
