About this study

Official title: Phase II Study of Radiation Therapy and Anti-PD-L1 Checkpoint Inhibitor (Durvalumab) With or Without Anti-CTLA-4 Inhibition (Tremelimumab) in Patients With Unresectable, Locally Advanced, or Metastatic Urothelial Bladder Cancer That Are Ineligible or Refusing Chemotherapy

This phase II trial studies the side effects and how well radiation therapy and durvalumab with or without tremelimumab work in treating participants with bladder cancer that cannot be removed by surgery, has spread to nearby tissue or lymph nodes, or that has spread to other parts of the body. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Monoclonal antibodies, such as durvalumab and tremelimumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving radiation therapy and durvalumab with or without tremelimumab will work better in treating participants with bladder cancer.

PRIMARY OBJECTIVES:

  1. To determine the safety profile of radiation therapy (RT) and durvalumab with or without tremelimumab. (Safety lead-in cohort) II. To determine the median progression-free survival with RT and durvalumab with or without tremelimumab. (Expansion cohort)

SECONDARY OBJECTIVES:

  1. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms of local control of irradiated bladder tumor.

II. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms of pathologic complete response (CR) rate of irradiated bladder tumor.

III. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms overall response rate.

IV. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms of abscopal response rate.

  1. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms of duration of response.

VI. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms of disease specific survival.

VII. To assess the efficacy of RT and durvalumab with or without tremelimumab in terms of overall survival.

VIII. To further determine the safety and tolerability of RT + durvalumab with or without tremelimumab (expansion cohorts).

EXPLORATORY OBJECTIVES:

  1. To explore the immunologic changes associated with the combination of durvalumab and RT +/- tremelimumab.

OUTLINE: Participants are randomized to 1 of 2 regimens.

REGIMEN A: Participants receive durvalumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 28 days for up to 13 courses in the absence of disease progression or unacceptable toxicity. Participants also undergo external beam radiation therapy (EBRT) for 5 fractions beginning on day 8 of course 1.

REGIMEN B:

Participants receive tremelimumab IV over 60 minutes on day 1 for up to 2 courses and durvalumab IV over 60 minutes on day 1. Treatment repeats every 28 days for up to 13 courses in the absence of disease progression of unacceptable toxicity. Participants also receive undergo EBRT for 5 fractions beginning on day 8 of course 1.

After completion of study treatment, participants are followed up at 8 weeks and then every 12 and 16 weeks.

What is being measured

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

  1. Incidence of adverse events assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 4.03 criteria (Safety lead-in cohort)

    Observed toxicities will be tabulated using frequencies and percentages based on the CTCAE v 4.03.

    Measured: Up to 90 days after last dose of investigation product

  2. Progression- free survival (PFS) assessed by Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1 (Expansion cohort)

    PFS will be estimated in each study arm by Kaplan-Meier estimate, where PFS is a composite endpoint based on radiologic progression, clinical deterioration or death. A log rank test will be used to test if there is significant difference in PFS between two arms. PFS will be also estimated for localized patients and metastatic patients separately within each arm and stratified log rank test will be used as well.

    Measured: From the first day of the treatment to the first occurrence of disease progression or death, assessed up to 3 years

Secondary outcomes (8)

  1. Local control at the primary irradiate site determined by RECIST v 1.1

    The stratified Kaplan Meier method will be used to describe local control for each arm along with their median.

    Measured: Up to 3 years

  2. Pathologic complete rate (CR) of primary irradiated tumor

    The point estimate and its 95% confidence interval will be obtained for the pathologic CR rate of the primary irradiated tumor for each arm and for localized patients and metastatic patients separately within each arm. A two-sample proportion test will be used to test if there is significant difference in pathologic CR (pCR) rates between two arms and the CochranMantel-Haenszel test will be used when accounting for the stratified design.

    Measured: Up to 3 years

  3. Overall response rate (ORR) defined as the number (%) of patients with at least 1 visit response of CR or partial response (PR) determined by RECIST v 1.1

    The point estimate and its 95% confidence interval of ORR will be obtained by arm and for localized patients and metastatic patients separately within each arm. A two-sample proportion test will be used to test if there is significant difference in ORR rates between two arms and the Cochran-Mantel-Haenszel test will be used when accounting for the stratified design.

    Measured: Up to 3 years

  4. Abscopal response (in patients with metastatic disease) determined by RECIST v 1.1 with response (PR and CR) sites away from the primary irradiated tumor

    The point estimate and its 95% confidence interval will be obtained by arm and for localized patients and metastatic patients separately within each arm. Furthermore, a two-sample proportion test will be used to test if there is significant difference between two arms and the Cochran-Mantel-Haenszel test will be used when accounting for the stratified design.

    Measured: Up to 3 years

  5. Duration of response

    The stratified Kaplan Meier method will be used to describe the duration of response for each arm along with their median.

    Measured: From date of the first documented response until the first date of documented progression or death, assessed up to 3 years

  6. Disease-specific survival

    The stratified Kaplan Meier method will be used to describe disease-specific survival for each arm along with their median.

    Measured: From the date of randomization to the date of death related to treatment and/or disease determined, assessed up to 3 years

  7. Overall survival

    The stratified Kaplan Meier method will be used to describe overall survival for each arm along with their median.

    Measured: From the date of randomization to the date of to the date of death due to any cause, assessed up to 3 years

  8. Incidence of adverse events assessed by National Cancer Institute CTCAE v4.0

    Will be summarized according to the subjects? baseline grade and maximum grade for each cycle of therapy.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Durvalumab, External Beam Radiation Therapy and Tremelimumab in people with Bladder Urothelial Carcinoma and Stage IV Bladder Cancer AJCC v8, run by Jonsson Comprehensive Cancer Center at 1 site 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 24 inclusion and 38 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: under way, not looking for participants, as of the sponsor's last update on 11 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 phase mean?

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?

This study is still under way. Results are not available in the source record yet.

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?

Incidence of adverse events assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 4.03 criteria (Safety lead-in cohort) (time frame: Up to 90 days after last dose of investigation product). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03601455.

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 11 May 2026.
