What this trial studies

This study explores the safety and effectiveness of combining high-intensity focused ultrasound (HIFU) with REGOTORI in patients suffering from drug-resistant metastatic colorectal cancer. Participants will receive localized HIFU treatment alongside REGOTORI, with clinical data collected at various follow-up points to assess outcomes. The study aims to gather comprehensive data, including laboratory results and imaging tests, to evaluate the treatment's impact on the patients' condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with metastatic colorectal cancer who have failed first and second-line treatments and have a target lesion suitable for HIFU.

Not a fit: Patients who are pregnant, have active infections, or have severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new treatment option for patients with metastatic colorectal cancer who have exhausted standard therapies.

How similar studies have performed: While the combination of HIFU and REGOTORI is a novel approach, similar studies using HIFU for cancer treatment have shown promising results.
