About this trial

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.

Eligibility criteria

Qualifiers

Histologically-confirmed diagnosis of stage IV non-squamous or squamous NSCLC.

Have measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 within one month of first vaccine. Target lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.

Have completed 3-4 cycles of chemoimmunotherapy, without evidence of progressive disease. Pembrolizumab has to be included in at least 3 of these cycles.

Have not received more than 2 cycles of maintenance pembrolizumab and/or pemetrexed and be a candidate for continuation of this therapy.

Disqualifiers

Symptomatic restrictive cardiomyopathy

Unstable angina within 4 months prior to enrollment

New York Heart Association functional class III-IV heart failure on active treatment

Symptomatic pericardial effusion
