What this trial studies

This clinical study focuses on elderly patients aged 65 and older with advanced triple-positive breast cancer (TPBC) who often struggle with traditional chemotherapy due to low physical status and treatment tolerance. The study aims to evaluate the safety and efficacy of a combination treatment involving darcilil, pyrrotinib, and aromatase inhibitors (AI) in this patient population. Participants will receive treatment until disease progression, intolerable toxicity, or withdrawal of consent, with regular assessments and follow-ups to monitor safety and treatment response. The study is designed as a single-arm, single-center, prospective trial with a planned enrollment of 28 patients.

Who should consider this trial

Good fit: Ideal candidates for this study are elderly patients aged 65 and older with histologically confirmed stage IV triple-positive breast cancer who have not received prior treatment for their condition.

Not a fit: Patients with early-stage breast cancer or those who have received prior anti-HER2 therapy within the last year may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more tolerable and effective option for elderly patients with advanced triple-positive breast cancer.

How similar studies have performed: While there have been studies on treatments for advanced breast cancer, this specific combination approach in elderly patients with triple-positive breast cancer is relatively novel.
