Further study details as provided by National Taiwan University Hospital:

Primary Outcome Measures:
  • evaluate the clinical responses of vaccinated patients 6 weeks after the first injection

Secondary Outcome Measures:
  • evaluate the safety of this treatment and the immune responses against CEA before and after the treatment 6 weeks after the first injection

Estimated Enrollment: 37
Study Start Date: July 2005
Estimated Study Completion Date: July 2005
Detailed Description:
In this trial, we will immunize metastatic colorectal cancer patients with recombinant CEA-pulsed DCs mixed with tetanus toxoid by subcutaneous injection. Low dose IL-2 will be given subcutaneously following DC vaccination to boost the growth of T cells. We will adapt “Simon’s optimal two-stage design” for this study. In the first stage, we will treat 12 patients to evaluate the safety of this new protocol. If there are no severe toxicities/side effects and there is at least one patient that had stable disease or better clinical response, then we will proceed to the second stage and treat additional 25 patients. We will follow the clinical outcome of these 37 patients. The immune responses against CEA before and after vaccination will be examined.

Ages Eligible for Study:   20 Years to 75 Years   (Adult, Senior)
