What this trial studies

This phase II clinical trial aims to evaluate the efficacy and safety of adaptive therapy in patients with HER2-negative metastatic breast cancer who have failed at least first-line treatment. The study will involve a single-arm approach where treatment regimens, including Gemcitabine, Vinorelbine, or Eribulin, will be selected by the investigator based on clinical guidelines and patient-specific factors. A total of 10 subjects will be recruited to assess the outcomes of this personalized treatment strategy.

Who should consider this trial

Good fit: Ideal candidates are women with HER2-negative metastatic breast cancer who have experienced treatment failure after at least one prior line of therapy.

Not a fit: Patients who are pregnant, breastfeeding, or have uncontrolled medical problems or significant organ dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a more tailored and effective treatment option for patients with advanced breast cancer.

How similar studies have performed: While adaptive therapy is a novel approach in this context, similar strategies have shown promise in other cancer types, suggesting potential for success.
