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-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 vaccine doses and a booster vaccine 9 weeks after the third vaccine dose. Patients also undergo computed tomography (CT) and biopsy during screening and on the trial, as well as blood sample collection on trial and during follow-up. ARM II: Patients receive sargramostim ID on day 14 of the 21-day maintenance therapy cycle for a series of 3 vaccine doses and a booster vaccine 9 weeks after the third vaccine dose. Patients also undergo CT and biopsy during screening and on the trial, as well as blood sample collection on trial and during follow-up. After completion of study treatment, patients are followed up twice yearly for up to 5 years. ;
