disease within 6 months after the last dose of systemic neoadjuvant or adjuvant
treatment, if applicable.

treatment. Exceptions include basal cell carcinoma of the skin or squamous cell
carcinoma of the skin that has undergone potentially curative therapy or in situ
cervical cancer.
2. Subject has a clinically active brain metastases or leptomeningeal metastases.
Participant who has a previously treated brain metastases or untreated asymptomatic
brain metastases =5 mm may participate provided that they are radiologically stable

of immunosuppressive therapy within 7 days prior to the first dose of study drug.
8. Subject has an active autoimmune disease that required systemic treatment in the past
2 years (ie, with use of disease modifying agents, corticosteroids or
immunosuppressive drugs).
9. Subject has received a live-virus or live-attenuated vaccine within 30 days prior to

13. Subject has a history of (non-infectious) pneumonitis that required steroids or
current pneumonitis.
14. Subject has a history of interstitial lung disease.
15. Subject has an active infection requiring systemic therapy.
16. Subject has a history or current evidence of any condition, therapy, or laboratory

participation for the full duration of the study, or is not in the best interest of
the subject to participate, in the opinion of the treating Investigator.
17. Participant has not recovered (ie, =Grade 1 or at baseline) from adverse events (AEs)

Summary
Brief summary
This is a Phase 2, Multi-Cohort, Open-Label, Multi-Center Study. Cohort 1 will be a
single-arm study of intratumoral tavokinogene telseplasmid (TAVO) plus electroporation (EP)
in combination with pembrolizumab therapy. Cohort 2 will be a single-arm study of
intratumoral TAVO-EP plus pembrolizumab along with treatment of an approved chemotherapy per
standard of care (either nab-paclitaxel (Abraxane®) or gemcitabine (Gemzar®) plus carboplatin
