简要总结
RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an immune response to kill tumor cells.
PURPOSE: This randomized phase I/II trial is studying the side effects of vaccine therapy and to see how well it works in treating patients with stage IIIB or stage IV non-small cell lung cancer who have finished first-line chemotherapy.
详细描述
OUTLINE: This is a multicenter study.
-
Phase I (single site [University of Miami Sylvester Comprehensive Cancer Center]): Patients receive allogeneic B7.1 and human leukocyte antigen-A1 (HLA-A1) transfected tumor cell vaccine intradermally (ID) in weeks 1, 3, and 5. Treatment repeats every 6 weeks for 2 courses. If no more than 1 of 6 patients experience a probable or definitively treatment related adverse effect (i.e., grade 2 autoimmune or grade 3-4 of any type), patients proceed to the phase II portion of the study. If 2 or more (out of 6) patients experience treatment related adverse effects the study stops.
-
Phase II (randomized): Patients are stratified according to study site (University of Miami Sylvester Comprehensive Cancer Center or Memorial Regional Hospital), type of prior first-line treatment (platinum and taxane vs platinum and gemcitabine), and presence of brain metastasis (yes vs no). Patients are randomized to 1 of 2 treatment arms.
-
Arm I: Patients receive allogeneic B7.1 and HLA-A1 transfected tumor cell vaccine ID in weeks 1, 3, and 5. Treatment repeats every 6 weeks for 2 courses.
-
Arm II: Patients receive a placebo vaccine as in arm I. Patients undergo blood sample collection periodically for correlative studies. Samples are analyzed for cluster of differentiation 8 (CD8), cluster of differentiation 4 (CD4), and natural killer cell (NK) response and peripheral blood lymphocytes (PBL) and T helper cell 1 (TH1)/T helper cell 2 (TH2) bias, including levels of interleukin (IL) IL-1β, IL-2, IL-4, IL-5, IL-6, IL-13, Interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α) via ELISA.
After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 4 years, and then once a year thereafter.
PROJECTED ACCRUAL: A total of 66 patients (6 patients for phase I and 60 patients for phase II) will be accrued for this study.

结局指标
主要结局
Preliminary Safety Profile (Phase 1)
时间窗: Up to 13 weeks
This will include the number of patients experiencing toxicity over the course of treatment, characterized by type of toxicity and grade, and by the time of toxicity onset in relation to day of vaccination.
Progression-free Survival (Phase 2)
时间窗: Date of randomization to the earliest date of documented progression.
次要结局
- Correlative Immunological Studies in Study Participants (Phase 2)(Baseline, Week 7 and Week 13)
- Safety Profile (Phase 2)(About 13 weeks)
- Immune Response (CD8) in B7-vaccinated Participants as Compared to Controls. (Phase 2)(About 13 weeks)
- Response to Second-line Chemotherapy After Disease Progression (Phase 2)(From Week 1 of Study Therapy until Death or Withdrawal of Consent)
- Relationship of CD8 Response in B7-vaccinated Patients to Their Progression-free Survival.(Phase 2)(From Week 1 of Study Therapy until Death or Withdrawal of Consent)
- Overall Survival (Phase 2)(Date of randomization to the recorded date of death)
