Brief Summary

This is a Phase I/IIA, open-label, multi-center trial to evaluate the safety, immunogenicity and preliminary clinical efficacy of INO-5401 + INO-9012 delivered by intramuscular (IM) injection followed by electroporation (EP), in combination with atezolizumab in participants with locally advanced unresectable or metastatic/recurrent Urothelial Carcinoma (UCa). The trial population is divided into two cohorts: Cohort A: Participants with locally advanced unresectable or metastatic/recurrent UCa, who have confirmed disease progression during or following treatment with anti-Programmed Death receptor-1/Programmed Death receptor Ligand-1 (anti-PD-1/PD-L1) therapy; Cohort B: Participants with locally advanced unresectable or metastatic/recurrent UCa, who are treatment naïve and ineligible for cisplatin-based chemotherapy. A safety run-in will be performed with up to six participants (safety analysis participants) from cohort A.

Study Groups

Cohort A

Participants with locally advanced unresectable or metastatic/recurrent UCa, who have confirmed disease progression during or following treatment with an anti-PD-1/PD-L1 therapy. Cohort A participants will be treated with INO-5401 and INO-9012 in combination with atezolizumab.

Group Type: EXPERIMENTAL

INO-5401

Intervention Type: BIOLOGICAL

INO-5401 (9 milligram \[mg\] dose IM): mixture of 3 synthetic plasmids that target Wilms' tumor gene-1 (WT1) antigen, prostate-specific membrane antigen (PSMA) and human telomerase reverse transcriptase (hTERT) antigen.

INO-9012

Intervention Type: BIOLOGICAL

INO-9012 (1 mg dose IM): A synthetic plasmid that expresses human interleukin-12 (IL-12).

INO-5401 + INO-9012 will be administered IM followed by EP with CELLECTRA™ 2000 device every 3 weeks for 4 doses then every 6 weeks for 6 additional doses, thereafter every 12 weeks until confirmed disease progression, unacceptable toxicity, or deemed intolerable by the investigator.

Atezolizumab

Intervention Type: DRUG

Atezolizumab will be administered by intravenous (IV) infusion every 3 weeks until confirmed disease progression, unacceptable toxicity, or deemed intolerable by the investigator.

CELLECTRA™ 2000

Intervention Type: DEVICE

IM injection of INO-5401 and INO-9012 is followed by EP with the CELLECTRA™ 2000 device.

Cohort B

Participants with locally advanced unresectable or metastatic/recurrent UCa who are treatment naïve and ineligible for cisplatin-based chemotherapy. Cohort B participants will be treated with INO-5401 and INO-9012 in combination with atezolizumab.
