Vaccine Therapy in Treating Patients With Liver Cancer
A Phase I/II Trial Testing Immunization With Dendritic Cells Pulsed With Four AFP Peptides in Patients With Hepatocellular Carcinoma
RATIONALE: Vaccines made from a person's white blood cells mixed with tumor proteins may make the body build an immune response to kill tumor cells.
PURPOSE: Phase I/II trial to study the effectiveness of vaccine therapy in treating patients who have liver cancer.

Detaljert beskrivelse
OBJECTIVES:
- Determine the maximum tolerated dose of alpha-fetoprotein peptide-pulsed autologous dendritic cells in HLA-A*0201-positive patients with hepatocellular carcinoma.
- Determine the safety and toxicity of this regimen in these patients.
- Determine the immunological effects of this regimen in these patients.
- Determine the progression-free survival and clinical responses in patients treated with this regimen.
OUTLINE: This is a dose-escalation study.
Patients receive alpha-fetoprotein peptide-pulsed autologous dendritic cells intradermally on day 1. Treatment repeats every 2 weeks for a total of 3 doses in the absence of unacceptable toxicity.
Cohorts of 3-12 patients receive escalating doses of vaccine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 or 2 of 12 patients experience dose-limiting toxicity.
Patients are followed at weeks 1, 4, and 12 and then every 6 months thereafter.
PROJECTED ACCRUAL: A total of 12-18 patients will be accrued for this study.

- Both male and female patients may be enrolled.
- Karnofsky Performance Status greater than or equal to 70 percent.
- No previous evidence of class 3 or greater New York Heart Association cardiac insufficiency or coronary artery disease.
- No previous evidence of opportunistic infection.

Increasing doses of AFP will be given to groups of 3 intradermally.
Subjects will receive 3 biweekly vaccinations.
At least 2 patients at a given dose must have received their complete 3 vaccination schedule with a 30 day observation period after the last vaccination before a higher dose is initiated.
