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
Prostate Cancer	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.

Criteria

Inclusion Criteria:

     • After cryosurgery, two PSA measurements of ≥ 2.0 ng/mL at least one week apart;
     • Other definitive surgical procedures may be permissible upon the approval of the medical monitor OR
   • After radiation therapy (e.g., external beam radiation, brachytherapy, or salvage/adjuvant radiation therapy after surgery), two post radiation PSA measurements level of nadir plus 2.0 ng/mL at least one week apart.;
