Infusion of activated NK cells for post-surgery colon cancer treatment

A Dose-Escalating Phase I Study to Determine the Safety, and Maximum Tolerated Dose/ Maximum Feasible Dose of Autologous ex Vivo Expanded and Activated NK Cell, Magicell-NK, Infusion for Colon Cancer Post Resection

Phase 1 Interventional Medigen Biotechnology Corporation · NCT05394714

This study is testing a new treatment using special immune cells to see if it can safely help people with early-stage colon cancer after their surgery.

What this trial studies

This Phase I open-label study investigates the safety and maximum tolerated dose of Magicell-NK, an infusion of autologous expanded and activated natural killer (NK) cells, in patients with stage I or stage IIa colon cancer following surgical resection. The study employs a 3+3 design to evaluate three different dose levels of NK cells. Participants will be monitored for safety and tolerability to determine the optimal dosing for future studies.

Who should consider this trial

Good fit: Ideal candidates are adults over 20 years old with histologically confirmed stage I or stage IIa colon cancer who have undergone curative resection within the last 4 to 8 weeks.

Not a fit: Patients with advanced colon cancer requiring adjuvant chemotherapy or those with significant postoperative complications may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could enhance the immune response against colon cancer, potentially improving patient outcomes post-surgery.

How similar studies have performed: While similar approaches using NK cell therapies have shown promise in other cancers, this specific application in early-stage colon cancer is novel and untested.
