About this study

Official title: Brachytherapy With Durvalumab (MEDI4736) and Tremelimumab in Subjects With Platinum-Resistant or Refractory and Recurrent or Metastatic Gynecological Malignancies

This phase II trial studies the side effects and how well brachytherapy with durvalumab or tremelimumab work for the treatment of gynecological malignancies that is resistant to platinum therapy (platinum-resistant), does not respond to treatment (refractory), has come back (recurrent), or has spread to other places in body (metastatic). Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial is being done to see whether brachytherapy with durvalumab or tremelimumab works better in treating patients with gynecological malignancies.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the safety of the treatment combination consisting of brachytherapy and tremelimumab. (Safety lead-in) II. To determine the median progression-free survival with brachytherapy and checkpoint inhibition with either durvalumab or tremelimumab. (Dose expansion)

SECONDARY OBJECTIVES:

  1. To estimate the efficacy of brachytherapy and durvalumab or brachytherapy and tremelimumab in terms of:

Ia. Local control of the irradiated tumor. Ib. Overall response rate. Ic. Response at non-irradiated lesions in subjects with multiple sites of disease subjects.

Id. Duration of response. Ie. Disease specific survival. If. Overall survival. II. To further determine the safety and tolerability of brachytherapy with durvalumab and brachytherapy with tremelimumab (expansion cohorts).

EXPLORATORY OBJECTIVE:

  1. To explore the immunologic changes associated with the combination of brachytherapy with durvalumab and brachytherapy with tremelimumab.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive durvalumab intravenously (IV) on day 1. Treatment repeats every 28 days for 13 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo brachytherapy on day 8. Treatment repeats every 21 days for 3 fractions in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive tremelimumab IV on day 1. Treatment repeats every 28 days for 2-4 cycles in the absence of disease progression or unacceptable toxicity. Patients then undergo brachytherapy on day 8. Treatment repeats every 21 days for 3 fractions in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 12 weeks.

What is being measured

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

  1. Incidence of adverse events (safety lead-in)

    Toxicity will be assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 5.0 criteria.

    Measured: Up to 90 days

  2. Progression free survival (PFS) (dose expansion)

    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. Furthermore, log rank test will be used to test if there is significant difference in PFS between two arms. In addition, PFS will be also estimated for localized subjects and metastatic subjects 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 as determined by Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1 or death, assessed up to 2 years

Secondary outcomes (6)

  1. Local control at the irradiated site

    Will be determined by RECIST v 1.1 from the date of randomization to the date of first local progression.

    Measured: Up to 2 years

  2. Overall response rate (ORR)

    ORR will be as determined by RECIST v 1.1. The ORR will be defined as the number (%) of subjects with at least 1 visit response of complete response (CR) or partial response (PR). Data obtained up until progression, or the last evaluable assessment in the absence of progression, will be included in the assessment of ORR. Subjects who go off treatment without progression receive a subsequent therapy, and then responds will not be included as responders in the ORR. The overall response rate will also be compared between treatment groups.

    Measured: Up to 2 years

  3. Response at non-irradiated lesions in subjects with multiple sites of disease

    As determined by RECIST v 1.1 with response (PR and CR) sites away from the primary irradiated tumor.

    Measured: Up to 2 years

  4. Duration of response (DoR)

    Will be defined as the time from the date of the first documented response until the first date of documented progression or death. The end of response should coincide with the date of progression or death from any cause used for the RECIST 1.1 PFS endpoint. The time of initial response will be defined as the latest of dates contributing towards the first visit response of CR or PR. If a subject does not progress following a response, then their DoR will be censored at the PFS censoring time. DoR will not be defined for those subjects who do not have a documented response.

    Measured: Up to 2 years

  5. Disease-specific survival

    Measured: From the first day of treatment to the date of death related to treatment and/or disease, assessed up to 2 years

  6. Overall survival

    Measured: From the first day of treatment to the date of death due to any cause as determined, assessed up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Durvalumab, Internal Radiation Therapy and Tremelimumab in people with Metastatic Malignant Female Reproductive System Neoplasm and Platinum-Resistant Malignant Female Reproductive System Neoplasm, 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 18 inclusion and 42 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 17 Jul 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 (safety lead-in) (time frame: Up to 90 days). 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 NCT04395079.

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 17 Jul 2026.
