INO-5401 + INO-9012 in Combination With Atezolizumab in Locally Advanced Unresectable or Metastatic/Recurrent Urothelial Carcinoma

Completed · Phase 1/Phase 2

Conditions studied: Urothelial Carcinoma

In brief

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.

You may qualify if…

Sign an Informed Consent Form (ICF);
Have histologically or cytologically documented locally advanced unresectable or metastatic/recurrent urothelial carcinoma (including renal pelvis, ureters, urinary bladder, and urethra);
For Cohort A: Subjects who have radiographically confirmed disease progression during or following treatment with an anti-PD-1/PD-L1 based therapy;
For Cohort B: No prior chemotherapy for inoperable locally advanced or metastatic or recurrent UCa and ineligible ("unfit") for cisplatin-based chemotherapy;
Have measurable disease, as defined by RECIST version 1.1;
Have a performance status of 0 or 1 on Eastern Cooperative Oncology Group (ECOG) Performance Scale;
Have life expectancy of >/= 3 months;
Be willing to provide a tissue sample for pre-treatment intra-tumoral assessment of proinflammatory and immunosuppressive factors;
Have electrocardiogram (ECG) with no clinically significant findings as assessed by the investigator performed within 28 days prior to first dose;
Demonstrate adequate hematological, renal, hepatic, and coagulation function;
For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 5 months after the last dose of study treatment;
For male subjects: agreement not to father a child. Participants must be surgically sterile (e.g, vasectomy) or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 5 months after the last dose of study treatment.

You may not qualify if…

Documented active or untreated central nervous system (CNS) metastases and/or carcinomatous meningitis;
Malignancies other than UCa within 3 years prior to Day 0, with the exception of those with negligible risk of metastasis or death treated with expected curative outcome;
