  • Patient is not able to swallow pills
  • Pregnant women are excluded from this study because XL184 and nivolumab are agents with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with XL184 and nivolumab, breastfeeding should be discontinued if the mother is treated with XL184 and nivolumab

About this study

Official title: A Randomized Phase 2 Study of Cabozantinib in Combination With Nivolumab in Advanced, Recurrent Metastatic Endometrial Cancer

This randomized phase II trial studies how well cabozantinib s-malate and nivolumab work in treating patients with endometrial cancer that has come back (recurrent) or spread to other places in the body (advanced or metastatic). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may work better in treating endometrial cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To evaluate the clinical anti-tumor activity of cabozantinib s-malate (XL184 ([cabozantinib]) and nivolumab based on progression free survival (PFS) in patients with advanced, recurrent or metastatic endometrial cancer previously treated with at least one line of platinum-based chemotherapy compared to patients receiving nivolumab alone.

SECONDARY OBJECTIVES:

  1. To evaluate the efficacy of XL184 and nivolumab in terms of overall response rate (ORR) compared to nivolumab alone.

II. To evaluate overall survival (OS) of patients receiving XL184 and nivolumab compared to patients receiving nivolumab alone.

III. To evaluate the safety of combination treatment using XL184 and nivolumab in patients with advanced, recurrent metastatic endometrial cancer.

IV. To evaluate correlation between PD-L1 expression, CD3, CD4 and CD8 infiltrates and outcome (PFS, ORR, OS).

  1. To compare PD-L1 expression, CD3, CD4 and CD8 infiltrates in the primary tumor (archival tissue) and in the tissue from baseline biopsy.

VI. To assess activity (PFS, ORR and OS) of nivolumab alone or in combination with XL184 according to microsatellite instability (MSI)/mismatched repair (MMR) status.

EXPLORATORY OBJECTIVES:

  1. To assess activity (PFS, ORR and OS) of XL184 and nivolumab in patients progressed after previous exposure to anti PD-1, PD-L1 or PD-L2 agents or crossed-over from single agent nivolumab, and in patients with diagnosis of carcinosarcoma.

II. To compare microsatellite (MS) and MMR status, in the primary tumor (archival tissue) and in the tissue from baseline biopsy.

III. To assess the genomic and immune-markers landscape at baseline on tumor tissue and changes in immune landscape in peripheral blood during treatment and correlate with outcome.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-28 and nivolumab intravenously (IV) over 30 minutes on days 1 and 15, then on day 1 beginning cycle 5. Patients undergo computed tomography (CT) scan, magnetic resonance imaging (MRI), and blood sample collection throughout the study and undergo biopsy at screening and optionally at follow up.

ARM B: Patients receive nivolumab as in Arm A. Patients may cross-over to Arm A at the time of disease progression. Patients undergo CT scan, MRI, and blood sample collection throughout the study and undergo biopsy at screening and optionally at follow up.

In both arms, cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30-37 days, then every 8-12 weeks.

What is being measured

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

  1. Progression Free Survival (PFS)

    PFS is defined as the interval between randomization and disease progression or death from any cause, which ever occurred earlier.

    Measured: Up to 1 year

Secondary outcomes (4)

  1. Overall Response Rate (ORR)

    Summary statistics, such as mean, median, counts and proportion, will be used to summarize the patients. Potential association between variables will be measured using Pearson correlation coefficients, chi-square tests, one- or two-sample t-tests or logistic regression analyses as appropriate. Non-parametric tests such as Spearman correlation coefficients, Fisher's exact tests and Wilcoxon rank sum test may be substituted if necessary. 95% percent confidence intervals will be constructed and selected results will be illustrated using figures and plots.

    Measured: Up to 1 year

  2. Overall Survival (OS)

    Survival estimates will be computed using the Kaplan-Meier method.

    Measured: Up to 4 years

  3. Incidence of Adverse Events

    Frequency and severity of adverse events will be tabulated using counts and proportions detailing frequently occurring, serious and severe events of interest.

    Measured: Up to 1 year

  4. PD-L1 Expression, CD3, CD4 and CD8 Analysis

    Correlated with outcomes (PFS, ORR, OS). The log rank test, cox model or Chi-Square test will apply to access the association between PD-L1, CD3, CD4, CD8 expression and outcome (PFS, OS, ORR) where appropriate.

    Measured: Up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Biopsy Procedure, Biospecimen Collection and Cabozantinib S-malate in people with Advanced Endometrial Carcinoma and Metastatic Endometrial Carcinoma, run by National Cancer Institute (NCI) at 34 sites in 2 countries.

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 23 inclusion and 57 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 9 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 34 sites in United States, Canada. 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?

Yes. Results are posted in the registry (first posted 29 Apr 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?

Progression Free Survival (PFS) (time frame: Up to 1 year). 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 NCT03367741, which also lists 1 linked publication.

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 9 Sep 2026.
