Study Details

Study Description

Brief Summary

This is a phase I, open-label trial to evaluate the safety and immunogenicity of INO 5150 alone or in combination with INO-9012 when delivered intramuscularly (IM) followed by electroporation (EP) in men with biochemically relapsed prostate cancer.

Condition or Disease Intervention/Treatment Phase
  • Biological: 2mg INO-5150 and electroporation device CELLECTRA®-5P
  • Biological: 8.5mg INO-5150 and electroporation device CELLECTRA®-5P
  • Biological: 2mg INO-5150 plus 1mg INO-9012 and electroporation device CELLECTRA®-5P
  • Biological: 8.5mg INO-5150 plus 1mg INO-9012 and electroporation device CELLECTRA®-5P
  • Device: Electroporation using CELLECTRA®-5P
 Phase 1

Detailed Description

Phase I, open label study of INO-5150 (DNA plasmids encoding prostate specific antigen (PSA) and prostate specific membrane antigen (PSMA)) alone or co-administered with INO-9012 (IL-12 plasmid) delivered intramuscularly followed by EP using the CELLECTRA®-5P device in adult males with biochemically relapsed prostate cancer following definitive local therapy (e.g. prostatectomy, external beam radiation, or brachytherapy). Four injections will be administered to approximately 60 eligible subjects who consent to participate in the study. Subjects will be monitored for safety and immunogenicity through Week 72.
