About this study

Official title: An Open-Label, Multi-Center Trial of INO-5401 + INO-9012 in Combination With Atezolizumab in Subjects With Locally Advanced Unresectable or Metastatic/Recurrent Urothelial Carcinoma

This was 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 was divided into two cohorts: Cohort A: participants with locally advanced unresectable or metastatic/recurrent UCa, who had 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 were treatment naïve and ineligible for cisplatin-based chemotherapy. A safety run-in was performed using a modified rolling six design, enrolling up to 6 participants (safety analysis participants) from Cohort A.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Adverse Events of Special Interest (AESIs) Treatment

    An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. TEAEs were defined as any AEs that occurred on or after Day 0. AESIs were toxicities and immune-mediated AEs that may have occurred up to 90 days after the last dose of trial treatment. AESIs were reported by the investigator to the Sponsor within 24 hours after learning of the event.

    Measured: Up to approximately 71 months

  2. Number of Participants With Clinically Significant Changes in Hematological Parameters

    Clinically significant changes in hematological parameters were determined based on the investigator's discretion.

    Measured: Up to approximately 71 months

  3. Number of Participants With Clinically Significant Changes in Serum Chemistry Parameters

    Clinically significant changes in serum chemistry parameters were determined based on the investigator's discretion.

    Measured: Up to approximately 71 months

  4. Number of Participants With Clinically Significant Changes in Urinalysis Parameters

    Clinically significant changes in urinalysis parameters were determined based on the investigator's discretion.

    Measured: At baseline, Weeks 3, 6, 9, then every 6 weeks thereafter, up to 71 months

  5. Antigen-Specific Immune Response

    Blood and tissue samples were collected to evaluate the antigen-specific immune response to INO-5401 + INO-9012 in combination with atezolizumab. Planned assessments included: Enzyme Linked Immunosorbent Spot-forming (ELISpot) Assay, Flow cytometry, T cell receptor (TCR) sequencing, ELISA and/or gene expression analysis.

    Measured: Up to approximately 71 months

  6. Objective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 by Investigator Review in Cohort A

    ORR was defined as the percentage of participants who had a confirmed complete response (CR) or a partial response (PR). CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters) per RECIST 1.1.

    Measured: From date of treatment start until date of first PD or death (whichever occurred first), up to approximately 71 months

Secondary outcomes (6)
  1. ORR as Assessed by RECIST Version 1.1 by Investigator Review in Cohort B

    ORR was defined as the percentage of participants who had a confirmed CR or a PR. CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters) per RECIST 1.1.

    Measured: From date of treatment start until date of first PD or death (whichever occurred first), up to approximately 71 months

  2. Percentage of Participants With ORR by Immune Response Evaluation Criteria in Solid Tumors (iRECIST)

    ORR was defined as the percentage of participants who had a confirmed CR or a PR. CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters) per iRECIST.

    Measured: From date of treatment start until date of first PD or death (whichever occurred first), up to approximately 71 months

  3. Duration of Response (DoR)

    DOR was defined as the time from the date of the first PR or CR to the date of death from any cause or date that progressive disease (PD) was objectively documented, whichever occurred first. CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters). PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on trial (nadir), including baseline. The sum also had to demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression.

    Measured: From first documented confirmed CR or PR until first documentation of PD or death, whichever occurred first (approximately 71 months)

  4. Progression-Free Survival (PFS) Per RECIST Version 1.1

    PFS was defined as the time from the date of the start of investigational product treatment until the date of death from any cause or date that progression (+1 day) was objectively documented, whichever occurred first as assessed by RECIST Version 1.1. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on trial (nadir), including baseline. The sum also had to demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression.

    Measured: From the first dose of study drug to date of PD or death, whichever occurred first (up to approximately 71 months)

  5. PFS Per Immune RECIST (iRECIST)

    PFS was defined as the time from the date of the start of investigational product treatment until the date of death from any cause or date that progression (+1 day) was objectively documented, whichever occurred first as assessed by iRECIST Version 1.1. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on trial (nadir), including baseline. The sum also had to demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression.

    Measured: From Baseline to disease progression or death, whichever occurs first (up to approximately 71 months)

  6. Overall Survival (OS)

    OS was defined as the time from the date of the start of investigational product treatment until the date of death from any cause.

    Measured: From date of first dose of study drug up to death from any cause, (approximately 71 months)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing INO-5401, INO-9012 and Atezolizumab in people with Urothelial Carcinoma, run by Inovio Pharmaceuticals at 11 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Sep 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Adverse Events of Special Interest (AESIs) Treatment (time frame: Up to approximately 71 months). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2026.
