What this trial studies

This phase 1 study evaluates the safety and preliminary effectiveness of combining bortezomib with cisplatin in women with recurrent or metastatic breast cancer. The trial aims to determine how well this combination works in patients who have not responded to standard treatments. Participants must have measurable lesions and meet specific health criteria to ensure their safety during the trial. The study will involve administering these medications and monitoring the patients for any side effects and treatment responses.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with confirmed recurrent or metastatic breast cancer who have failed standard treatments.

Not a fit: Patients with early-stage breast cancer or those who have not yet undergone standard treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment combination could offer a new therapeutic option for patients with advanced breast cancer who have limited alternatives.

How similar studies have performed: While this approach is novel, similar studies combining targeted therapies with chemotherapy have shown promise in other cancer types.
