Trial summary

Secondary angiosarcomas are aggressive mesenchymal tumors with a poor prognosis and limited therapeutic options. Recent studies conducted in patients with cutaneous squamous-cell carcinoma provide evidence that cemiplimab has the potential to be an effective treatment also for patients with secondary angiosarcomas.

About this study

Official title: Cemiplimab Treatment in Patients with Locally Advanced and Metastatic Secondary Angiosarcomas

Secondary angiosarcomas are aggressive mesenchymal tumors with a poor prognosis and limited therapeutic options. Recent studies conducted in patients with cutaneous squamous-cell carcinoma provide evidence that cemiplimab has the potential to be an effective treatment also for patients with secondary angiosarcomas.

The purpose of this study is to evaluate the overall response rate after 24 weeks of cemiplimab treatment in patients with locally advanced or metastatic secondary angiosarcomas.

The investigators hypothesis is that cemiplimab could be an effective treatment for patients diagnosed with locally advanced and metastatic secondary angiosarcomas.

Read the detailed description

Study design: A prospective, interventional, non-randomized, multicenter, phase II clinical trial.

Hypothesis:

Cemiplimab is registered for the use in patients with cutaneous squamous-cell carcinoma. In these patient groups cemiplimab showed impressive results. There are numerous similarities between cutaneous squamous-cell carcinoma and secondary angiosarcomas. Based on these similarities, including a complex genetic background, PD-L1 expression and MYC expression, the investigators hypothesize that cemiplimab might be an effective treatment for locally advanced and metastatic secondary angiosarcomas.

Primary Objective:

To evaluate the overall response rate (ORR) after 24 weeks of cemiplimab in secondary angiosarcomas, according to Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 or daylight photography as per WHO Offset Publication No. 48.

Secondary Objectives:

Secondary objectives include the establishment of the best ORR, median time to response, duration of response and progression free survival. The secondary objectives also comprise safety and toxicity quantification and to investigate the relation between response to cemiplimab and various tumor characteristics.

Study Population:

Patients eligible for inclusion are at least 18 years of age, with adequate organ function, who have a histologically confirmed diagnosis of progressive unresectable locally advanced or metastatic secondary angiosarcoma. Patients eligible are patients in the first line of treatment if they are unfit for chemotherapy and patients in advanced lines of systemic treatment. Major exclusion criteria include significant ongoing autoimmune disease that requires immunosuppressive treatment, prior treatment with immune checkpoint inhibitors, active uncontrolled infections or recent pneumonitis. All patients will provide Informed Consent prior to inclusion in the study and during the course of the trial, al relevant data will be stored in electronic Case Report Forms (eCRF).

Treatment Schedule:

After study inclusion, patients will be treated with Cemiplimab 350mg intravenously every three weeks. Patients will receive treatment until disease progression or discontinuation due to unacceptable toxic effects, withdrawal of consent or other reasons. The maximum treatment period will be two years, as is standard of care for patients treated with immunotherapy.

What is being measured

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

  1. Overall Response Rate (ORR) after 24 weeks of cemiplimab

    To evaluate the overall response rate (ORR) after 24 weeks of cemiplimab in secondary angiosarcomas, according to Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 or daylight photography as per WHO Offset Publication No. 48.

    Measured: From the date of study inclusion until 24 weeks after inclusion. Interim analysis after 13 patients

Secondary outcomes (8)
  1. Best Overall Response Rate

    To establish the best ORR of patients with secondary angiosarcomas receiving cemiplimab

    Measured: From the date of study inclusion to the end of the treatment period. Assessed up to 2 years after inclusion

  2. Time to response and duration of response

    To establish the median time to response (TTR) and duration of response (DOR) in patients with secondary angiosarcomas receiving cemiplimab.

    Measured: From the date of study inclusion to the date of response or progression. Assessed up to 2 years after inclusion

  3. Progression free survival (PFS)

    To assess the median progression-free survival (PFS) of patients with secondary angiosarcomas receiving cemiplimab

    Measured: Counting from the date of study inclusion to the date of progressive disease or death. Assessed up to 2 years after inclusion.

  4. Overall survival (OS)

    To establish the overall survival (OS) of patients with secondary angiosarcomas receiving cemiplimab

    Measured: From the date of study inclusion to the date of death. If study medication is discontinued for any reason, survival follow-up takes place every 12 weeks, also assessed up to 2 years

  5. Relation between tumor characteristics and response to treatment

    To investigate possible relations between response to cemiplimab and tumor characteristics (i.e. PD-L1 expression, tumour infiltrating lymphocytes, MYC status and tumour mutational burden)

    Measured: 2-3 years

  6. Differences between UV associated and radiation induced secondary angiosarcomas

    To assess differences in response to cemiplimab between UV associated and radiation induced secondary angiosarcomas

    Measured: 2-3 years

  7. Effect on tumor tissue

    To assess effects of cemiplimab on tumor tissue by comparing pre- and post-treatment biopsies

    Measured: At specific timepoints tumor biopsies and liquid biopsies will be obtained. Tumor biopsies will be obtained at baseline, after 12 weeks and (voluntary) at end of treatment

  8. Adverse events and toxicity

    To quantify toxicity during cemiplimab treatment

    Measured: From the date of inclusion until the end of the study (by progression or at the end of the treatment period, up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cemiplimab in people with Secondary Angiosarcoma and Locally Advanced Sarcoma, run by Radboud University Medical Center at 1 site in Netherlands.

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 19 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 31 Oct 2024. 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 Netherlands. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Overall Response Rate (ORR) after 24 weeks of cemiplimab (time frame: From the date of study inclusion until 24 weeks after inclusion. Interim analysis after 13 patients). 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 31 Oct 2024.
