Is this trial a fit for you?

Likely a good fit

Ideal candidates are female patients over 18 years old with advanced triple-negative breast cancer who are scheduled to receive neoadjuvant chemotherapy.

Probably not a fit

Patients who are pregnant, breastfeeding, or have previously received chemotherapy or statin therapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effects of simvastatin on the epithelial-mesenchymal transition (EMT) process in patients with triple-negative breast cancer (TNBC) undergoing neoadjuvant chemotherapy. It aims to evaluate whether the combination of simvastatin and chemotherapy can enhance therapeutic responses by targeting EMT markers, particularly vimentin, which is associated with cancer aggressiveness and resistance to treatment. Female patients with advanced TNBC will receive either simvastatin or a placebo alongside their chemotherapy regimen over eight cycles. The study seeks to determine if simvastatin can improve outcomes for these patients.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment responses and outcomes for patients with triple-negative breast cancer.

How similar studies have gone: While the use of statins in cancer treatment is being explored, this specific combination approach with simvastatin and neoadjuvant chemotherapy in TNBC is relatively novel and has not been extensively tested.
