Clinical Trial Summary

This phase II trial tests whether CD105/Yb-1/SOX2/CDH3/MDM2-polyepitope plasmid DNA vaccine (STEMVAC) works to shrink tumors in patients with stage IV non-squamous non-small cell lung cancer. STEMVAC targets specific immunogenic proteins that help lung cancer cells to grow. STEMVAC is made up of deoxyribonucleic acid (DNA), which is a natural substance in every living organism. DNA acts like a blueprint that tells all the cells in your body how to function. The DNA used in this study contains instructions for your body to produce parts of the 5 proteins the investigators identified (CDH3, CD105, YB-1, MDM2 and SOX2). STEMVAC is given with granulocyte-macrophage colony stimulating factor (GM-CSF) which is being used as an adjuvant to help create a stronger immune response. Giving STEMVAC with GM-CSF to patients while on maintenance therapy for non-small cell lung cancer (NSCLC) may help activate certain immune cells to recognize and kill lung cancer cells.


Clinical Trial Description

OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive STEMVAC intradermally (ID) and sargramostim ID on day 14 of the 21-day maintenance therapy cycle for a series of 3 vaccines doses and a booster vaccine 9 weeks after third vaccine dose. ARM II: Patients receive sargramostim ID on day 14 of the 21-day maintenance therapy cycle for a series of 3 vaccines doses and a booster vaccine 9 weeks after third vaccine dose. After completion of study treatment, patients are followed up twice yearly for up to 5 years. ;
