DNA Plasmid-encoding Interleukin-12/HPV DNA Plasmids Therapeutic Vaccine INO-3112 and Durvalumab in Treating Patients With Recurrent or Metastatic Human Papillomavirus Associated Cancers

A Phase 2, Open-Label Study to Evaluate Efficacy of Combination Treatment With MEDI0457 (INO-3112) and Durvalumab (MEDI4736) in Patients With Recurrent/Metastatic Human Papilloma Virus Associated Cancers

This phase II trial studies how well deoxyribonucleic acid (DNA) plasmid-encoding interleukin-12/human papillomavirus (HPV) DNA plasmids therapeutic vaccine INO-3112 and durvalumab work in treating patients with human papillomavirus associated cancers that have come back or spread to other places in the body. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving DNA plasmid-encoding interleukin-12/HPV DNA plasmids therapeutic vaccine INO-3112 and durvalumab may work better in treating patients with human papillomavirus associated cancers.

OUTLINE:

Patients receive DNA plasmid-encoding interleukin-12/HPV DNA plasmids therapeutic vaccine INO-3112 intramuscularly (IM) and via electroporation at 1, 3, 7, and 12 weeks and durvalumab intravenously (IV) at 4, 8, and 12 weeks. Starting week 12, cycles repeat every 8 weeks for DNA plasmid-encoding interleukin-12/HPV DNA plasmids therapeutic vaccine INO-3112 and every 4 weeks for up to 13 doses of durvalumab in the absence of disease progression or unacceptable toxicity.
