Phase II Study of Lucanix™ in Patients With Stages II-IV Non-Small Cell Lung Cancer

This will be a 2-stage, open-label, three-arm, Phase II study. It is designed to evaluate the efficacy of immunization with increasing doses of an allogeneic tumor cell vaccine, Lucanix™, in patients with non-curable NSCLC. Patients will be followed for clinical response, immunogenicity and safety.

Eligible patients will receive 4 monthly intradermal injections with a cell cocktail comprised of equal numbers of four irradiated allogeneic TGF-beta2 antisense gene modified NSCLC cell lines. Patients will be randomized to one of the three study cohorts. Patients will receive 12,500,000, 25,000,000, 50,000,000 gene modified cells respectively. Treated patients will be evaluated four months after they enter therapy. Patients that respond to therapy will receive an additional four to twelve injections to evaluate whether their response to therapy can be amplified. Response, time to tumor progression, and tumor free survival will be monitored in patients and compared with historical controls and patients receiving other forms of therapy. Patients will be monitored and evaluated according to standard evaluation criteria of no response, stable disease, partial response and complete response.

PRIMARY OBJECTIVE

-Evaluate the ability of increasing doses of Lucanix™, a gene-modified tumor cell vaccine, to induce tumor response in patients with non-curable NSCLC

SECONDARY OBJECTIVES

• Evaluate the ability of the Lucanix™ vaccination regimen to induce an immune response (cellular and humoral)
• Estimate the response duration for the Lucanix™ regimen
• Evaluate the effects of repeated inoculations on immune infiltrates
• Evaluate the safety of the Lucanix™ regimen

Inclusion criteria
