Immunotherapy for Lung Carcinoma - Phase II Trial of Autologous Cancer Antigen Specific Immunotherapy

OBJECTIVES:

- Evaluate the efficacy of immunotherapy with irradiated autologous tumor cell vaccine
plus sargramostim (GM-CSF) followed by monoclonal antibody OKT3- activated T
lymphocytes and interleukin-2 in combination with standard therapy in terms of response
rate in patients with stage II, III, or IV small cell or non-small cell lung cancer.

- Determine the immunogenicity of lung cancer in this patient population.

OUTLINE: Patients are stratified according to extent of disease, extent of antigen specific
response to vaccination, performance status (0 vs 1), prior therapy (yes vs no), and gender.

Patients undergo surgical debulking of tumor on week 1 followed by adjuvant chemotherapy.
Within 2-4 weeks of chemotherapy, patients are vaccinated with irradiated autologous tumor
cells and sargramostim (GM-CSF), then receive GM-CSF alone intradermally at vaccination
sites daily for 4 days. Patients are revaccinated 2 weeks later.

Patients undergo peripheral blood mononuclear cell collection two weeks after the second
vaccination. Peripheral blood mononuclear cells are stimulated with anti-CD3 monoclonal
antibody (OKT3) and interleukin-2, producing activated T lymphocytes. The activated T
lymphocytes are infused IV over 1-6 hours followed by 5 doses of interleukin-2 IV every
other day over 10 days. Treatment continues in the absence of disease progression or
unacceptable toxicity.

Patients may receive one additional course of immunotherapy as above.

Patients are followed every 3 months for 2 years, then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 90 patients will be accrued for this study.
