About this study

Official title: A Phase 2 Study of Nivolumab and Ipilimumab in Advanced Leiomyosarcoma of the Uterus

This phase II trial studies how well nivolumab alone or in combination with ipilimumab works in treating patients with uterine cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment. Monoclonal antibodies, such as nivolumab and ipilimumab, may interfere with the ability of tumor cells to grow and spread.

II. To evaluate the objective response rate per RECIST 1.1 of patients with advanced ULMS treated with nivolumab in combination with ipilimumab.

SECONDARY OBJECTIVES:

  1. To evaluate the toxicity of nivolumab in patients with advanced ULMS. II. To evaluate the toxicity of nivolumab in combination with ipilimumab in patients with advanced ULMS.

III. To evaluate the progression-free survival of ULMS treated with nivolumab. IV. To evaluate the progression-free survival of ULMS treated with nivolumab in combination with ipilimumab.

  1. To explore the relationship between PDL1, PD1 in infiltrating lymphocytes and PD2 status in archival tumor, and pre/post treatment biopsies in a minimum of 10 patients.

TERTIARY OBJECTIVES:

  1. To explore the relationship between general immune response and specific markers of immunomodulation and response to nivolumab.

II. To explore the relationship between tumor inflammatory gene signature and response to nivolumab in archival material.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

Cohort A (closed to accrual on 21-Oct-2015): Patients receive nivolumab intravenously (IV) over approximately 60 minutes once every 2 weeks for up to 46 doses in the absence of disease progression or unacceptable toxicity.

Cohort B: Patients receive nivolumab IV over approximately 60 minutes followed by a saline flush and ipilimumab IV over 90 minutes. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

What is being measured

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

  1. Objective Response Per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 Among Patients With Advanced Leiomyosarcoma of the Uterus (ULMS) Treated With Nivolumab (Cohort A)

    For the primary endpoint of overall response with a null hypothesis of 5% and an alternative hypothesis of 20%, 37 patients are needed in a two-stage design with 12 patients in the first stage and 25 patients in the second stage. At the first stage analysis, overall response, at least 1 response out of 12 patients will need to be observed to continue through the second stage. At the second stage, at least 4 responses out of 37 patients will need to be observed to accept the treatment. The overall power for overall response rate is 90%. The overall type I error, the chance of incorrectly rejecting the null hypothesis is 9%. The probability of stopping at the first stage under the null hypothesis is 54%. The operating characteristics of this design are calculated using the exact binomial distribution.

    Measured: Up to 100 days

  2. Objective Response Per RECIST 1.1 Among Patients With Advanced ULMS Treated With Nivolumab and Ipilimumab (Cohort B)

    For the primary endpoint of overall response with a null hypothesis of 5% and an alternative hypothesis of 30%, 25 patients are needed in a two-stage design with 8 patients in the first stage and 17 patients in the second stage. At the first stage analysis, overall response, at least 1 response out of 8 patients will need to be observed to continue through the second stage. At the second stage, at least 3 responses out of 25 patients will need to be observed to accept the treatment. The overall power for overall response rate is 94%. The overall type I error, the chance of incorrectly rejecting the null hypothesis is 9%. The probability of stopping at the first stage under the null hypothesis is 66%. The operating characteristics of this design are calculated using the exact binomial distribution.

    Measured: Up to 100 days

Secondary outcomes (5)

  1. Incidence of Toxicity, Graded Using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (Version 5.0 Beginning April 1, 2018) (Cohort A)

    Among the first phase of 12 patients, there is at least 58% probability of observing one or more rare (7% true probability) events, and 83% probability of observing toxicities that have a true occurrence of at least 15%. Among the total cohort of 37 patients, there is at least 85% probability of observing one or more rare (5% true probability) events, and 95% probability of observing toxicities that have a true occurrence of at least 8%. With 37 treated patients, the maximum width of a 90% two-sided exact binomial confidence interval for any estimated adverse event proportion will be no wider than +/- 14%.

    Measured: Up to 4 cycles

  2. Incidence of Toxicity, Graded Using the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (Version 5.0 Beginning April 1, 2018) (Cohort B)

    Among the first phase of 8 patients, there is at least 57% probability of observing one or more rare (10% true probability) events, and 73% probability of observing one or more toxicities that have a true occurrence rate as low as 15%. Among the total cohort of 25 patients, there is at least 84% probability of observing one or more rare (7% true probability) events, and 93% probability of observing toxicities that have a true occurrence of at least 10%. With 25 treated patients, the maximum width of a 90% two-sided exact binomial confidence interval for any estimated adverse event proportion will be no wider than +/- 18%.

    Measured: Up to 4 cycles

  3. Rate of Progression-free Survival (Cohort A)

    A null hypothesis of 20% and an alternative hypothesis of 40% at 12 weeks will be investigated. Patients lost to follow-up or deaths within 12 weeks will be counted as failures. The overall power for overall progression-free rate at 12 weeks is 87%, using the exact binomial distribution. The operating characteristics of this design are calculated using a one-sided exact test with 10% type I error.

    Measured: Time from start of treatment to time of progression or death, whichever occurs first, assessed at 12 weeks

  4. Rate of Progression-free Survival (Cohort B)

    A null hypothesis of 18% and an alternative hypothesis of 40% at 6 months will be investigated. Patients lost to follow-up or deaths within 6 months will be counted as failures. The overall power for overall progression-free rate at 6 months is 85%, using the exact binomial distribution. The operating characteristics of this design are calculated using a one-sided exact test with 10% type I error.

    Measured: Time from start of treatment to time of progression or death, whichever occurs first, assessed at 6 months

  5. PDL1 Status

    The relationship between PDL1 status and response to nivolumab will be explored. A Fisher's exact test will be used to assess the relationship between each biomarker and response to treatment. The power to detect the relationship of interest increases as the prevalence of the biomarker increases.

    Measured: Up to 100 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ipilimumab, Laboratory Biomarker Analysis and Nivolumab in people with Metastatic Leiomyosarcoma and Unresectable Leiomyosarcoma, run by National Cancer Institute (NCI) at 2 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 17 inclusion and 16 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 25 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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 12 May 2020). 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?

Objective Response Per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 Among Patients With Advanced Leiomyosarcoma of the Uterus (ULMS) Treated With Nivolumab (Cohort A) (time frame: Up to 100 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 NCT02428192.

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 25 Feb 2025.
