Phase II Trial of Individualized Mutant p53 Peptide-Pulsed Cultured Autologous Dendritic Cells in the Adjuvant Treatment of Patients With Locally Advanced Non-Small Cell Lung Cancer After Standard Therapy

OBJECTIVES:

• Determine the overall survival in patients with locally advanced non-small cell lung cancer immunized with adjuvant mutant p53 peptide-pulsed autologous dendritic cells after standard therapy.
• Assess the safety and immunological efficacy of this regimen in terms of inducing or boosting a mutant p53-specific immune response in this patient population.

OUTLINE: Patients undergo p53 gene mutation analysis. Patients without a suitable gene mutation receive no vaccination. Patients with a suitable p53 gene mutation receive mutant p53 peptide-pulsed autologous dendritic cells IV over 1-2 minutes weekly for 5 weeks. Patients achieving an immune response with no evidence of progressive disease may receive additional vaccinations every 2 months for a maximum of 10 immunizations.

Patients are followed for 5 years.

PROJECTED ACCRUAL: Approximately 120 patients (40 on the vaccination arm) will be accrued for this study.
