Using PET/CT imaging to predict treatment response in triple-negative breast cancer

Official title: 68Ga-FAPI-46 PET/CT for Predicting Histological Response to Neoadjuvant Chemo-immunotherapy in Triple-negative Breast Cancer

Run by Institut Curie · NCT06349512 · Data updated 2026-11-12

This study is testing if a special type of imaging can help predict how well early-stage triple-negative breast cancer patients will respond to their treatment with pembrolizumab and chemotherapy.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are females aged 18 and older with untreated, non-metastatic, centrally confirmed triple-negative breast cancer who are eligible for neoadjuvant chemotherapy with pembrolizumab.

Probably not a fit

Patients who are pregnant, have prior anti-PD(L)1 immunotherapy, or have contraindications to the standard treatment will not benefit from this study.

What this trial studies

This prospective multicenter study evaluates how well 68Ga-FAPI-46 PET/CT imaging can predict histological response in patients with early-stage high-risk triple-negative breast cancer (TNBC) undergoing neoadjuvant treatment with pembrolizumab and chemotherapy. Patients will receive standard neoadjuvant therapy, including pembrolizumab and a combination of chemotherapy agents, followed by surgery and adjuvant pembrolizumab. The study aims to perform PET/CT scans before treatment to assess their effectiveness in predicting patient outcomes. The results could help tailor treatment plans based on individual responses.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized treatment strategies for patients with triple-negative breast cancer, potentially improving outcomes.

How similar studies have gone: While similar imaging approaches have been explored, this specific use of 68Ga-FAPI-46 PET/CT for predicting treatment response in TNBC is relatively novel.
