Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE1
• Total Enrollment: 1 participants

Brief Summary

The purpose of this study is to test an experimental anti-cancer immunotherapy called NKR-2 (modified T cells), to treat colorectal cancer with unresectable liver metastases. The trial will test three dose levels (dose escalation). At each dose, the patients will receive three successive hepatic transarterial administrations, two weeks apart, of NKR-2 cells. The study will enroll up to 18 patients.
