Male patients must have been surgically sterile, or must have agreed to use contraception during the study and at least 30 days following the last day of study drug administration (addendum).~* Had a creatinine level \< 2 x upper limit of normal (ULN), and serum bilirubin within institutional normal limits obtained within 4 weeks prior to enrollment (main part and addendum).~* Had aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \< 1.5 x ULN within 4 weeks prior to enrollment (addendum).~* Had an absolute neutrophil count (ANC) \> 1000/mm and platelet count \> 100,000 /mm within 4 weeks prior to registration (main part) or enrollment (addendum).~* Were able to give informed consent and to follow guidelines given in the study (main part and addendum).~Exclusion Criteria:~* Prior therapy with IL-12 or prior gene therapy (main and addendum).~* Had an ECOG performance score of 3 or 4 (main part).~* Concurrent immunotherapy, chemotherapy, or radiation therapy for duration of patient participation on study (main part and addendum). For the study addendum, approved anti PD1 agents could have been permitted at the investigator's discretion and in consultation with the sponsor's medical monitor.~* Evidence of significant active infection (e.g., pneumonia, cellulitis, wound abscess, etc.) at time of study entry (main part) or enrollment (study addendum).~* Pregnant or breast-feeding women (main part and addendum).~* Women of childbearing age must have had a negative pregnancy test and had to be willing to use a highly effective method of contraception. Men who were sexually active must also have been willing to use an accepted and effective method of contraception (main part).~* Patients with electronic pacemakers or defibrillators are excluded from this study (main part and addendum).~* The patient is known to be positive for Human Immunodeficiency Virus (HIV) or has another confirmed or suspected immunosuppressive or immunodeficient condition (patients with thyroiditis are eligible) (addendum).~* Life expectancy of less than 6 months (main part and addendum).~* Had significant disease or uncontrolled disease, ie, cardiovascular renal, hepatic, endocrine, metabolic, neurologic, or other significant disease that could have limited the patient's ability to participate in the study as determined by the investigator or medical monitor (main part).~* History of significant cardiovascular disease (i.e. New York Heart Association (NYHA) class 3 congestive heart failure; myocardial infarction with the past 6 months; unstable angina; coronary angioplasty with the past 6 months; uncontrolled atrial or ventricular cardiac arrhythmias) (study addendum).~* Other clinically significant co-morbidities such as uncontrolled pulmonary disease, uncontrolled diabetes, active central nervous system (CNS) disease, active infection or any other condition that could compromise the patients participation in the study according to the investigator (study addendum).

Study Arms:
- Main Study: tavo-EP (Type: EXPERIMENTAL): Patients received one cycle (3 daily treatments on Days 1, 5, and 8) of intra-tumoral injection(s) of tavo at a fixed dose of 0.5 mg/mL (up to 4 tumor sites) followed immediately by in vivo electroporation. Treatment could be repeated at 3-month intervals until disease progression or unacceptable toxicity for up to 5 cycles.
- Addendum: Regimen A tavo-EP (Type: EXPERIMENTAL): Patients received one cycle (3 daily treatments on Days 1, 8, and 15) of intra-tumoral injection(s) of tavo at a fixed dose of 0.5 mg/mL (up to 4 tumor sites) followed immediately by in vivo electroporation. Treatment could be repeated at 6-week intervals until disease progression or unacceptable toxicity for up to 9 cycles.
- Addendum: Regimen B tavo EP (Type: EXPERIMENTAL): Patients received one cycle (3 daily treatments on Days 1, 5, and 8) of intra-tumoral injection(s) of tavo at a fixed dose of 0.5 mg/mL (up to 4 tumor sites) followed immediately by in vivo electroporation. Treatment could be repeated at 6-week intervals until disease progression or unacceptable toxicity for up to 2 cycles.
