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

Study Overview
=================
Brief Summary
-----------------
In this Phase II clinical trial the investigators will use four human non-small cell lung cancer cell lines that have been previously established in tissue culture laboratory. The investigators will gene modify these tumor cells in the laboratory to block their TGF-beta secretion. The investigators will inject the genetically engineered cells as vaccines in patients with stages II to IV non-small cell lung cancer. Our rationale for using other people's tumor cells is that lung tumor cell lines belonging to different people have been shown to share common characteristics that are recognized by non-self immune systems.

Detailed Description
-----------------
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 Signed informed consent 18 years Histologically confirmed non-curable NSCLC with an estimated total tumor burden volume of less than or equal to 125 cc, confirmed to be stage II, III, or IV. Must have completed or refused conventional therapy Performance status (ECOG) less than 2. Absolute granulocyte count greater than or equal to 1,500/mm3 Platelet count greater than or equal to 100,000/mm3 Total Bilirubin less then or equal to 2 mg/dL AST and ALT less than or equal to 2x Upper Limit of Normal Creatinine less than or equal to 1.5 mg/dL EXCLUSION CRITERIA Concurrent systemic steroids greater than 2 mg prednisone/day Prior splenectomy Any surgery involving general anesthesia, chemotherapy, radiotherapy, steroid therapy or immunotherapy less than 4 weeks of study entry Brain metastases or meningeal lymphomatosis unless treated and stable for greater than or equal to 2 months Known HIV positive Serious non-malignant disease (e.g., congestive heart failure, or active uncontrolled bacterial, viral, or fungal infections), or other conditions which, in the opinion of the investigator would compromise protocol objectives. Prior malignancy (excluding nonmelanoma carcinomas of the skin) unless in remission for greater than or equal to 2 years Treatment with an investigational drug within 30 days prior to study entry History of psychiatric disorder that would impede adherence to protocol Pregnant or nursing women or refusal to practice contraception if of reproductive potential
