Safety Assessment (Composite of multiple measures: adverse events, pain (VAS), lab abnormalities, changes in vital signs)
Composite of multiple measures consist of:
* Frequency and severity of all adverse events
* Local pain immediately and at 5 and 10 minutes after Study Treatment/EP using a visual analog scale from 0 to 10, with 0 representing "No Pain" and 10 representing "Worst Pain"
* Frequency and severity of local and systemic events for at least 7 days after Study Treatment/EP
* Frequency and severity of laboratory abnormalities
* Changes in vital signs (blood pressure, heart rate, respiratory rate, temperature)
Screening through up to 60 weeks following the first dose

Less than two acceptable sites exist for intramuscular or intradermal injection and EP between use of the deltoid and lateral quadriceps muscles. A site for injection/EP is not acceptable if there are tattoos, keloids or hypertrophic scars within 2 cm of the injection/EP site.
Subject has significant acute or chronic medical illness if deemed by the practitioner that electroporation treatment could negatively impact the illness
Subject has unstable or life-threatening cardiac disease (e.g. unstable angina, class 3 or higher congestive heart failure)
Subject has an acute or chronic bleeding or clotting disorder that would contraindicate IM injections or use of blood thinners (e.g. anticoagulants or antiplatelet drugs) within 2 weeks;
Subject has a cardioverter-defibrillator or pacemaker (to prevent a life-threatening arrhythmia) that is located ipsilateral to the intended deltoid injection site (unless deemed acceptable by a Cardiologist);
