Vestibular Schwannoma Organoids

January 28, 2026 updated by: Maastricht Radiation Oncology

Vestibular Schwannoma Stem Cell Organoids

In standard of care regularly planned surgery, tissue will be obtained from patients who are suspicious for having vestibular Schwannoma (on MRI). The tissue that remains after the pathologist gathered sufficient for analysis, the remaining tissue is used for creating tumour stem cell organoids.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This project constitutes scientific research since the presence of tumor stem cells has not been shown in schwannoma before. Secondly the organoid model has not yet been described for VSs. The correlation between effect in schwannoma organoids and in patients has to be evaluated but can proof to be very valuable since it has been shown in a number of tumors. The tumor tissue will be acquired during regularly planned surgery. The tissue that is used is what is left after sufficient material has been sent to the pathologist to make the diagnosis. So the tissue that is used is removed routinely during surgery, but instead of banking it at the pathology department, it is used for the research project. Blood samples that can be used to compare normal DNA to tumor cells DNA will be acquired from central lines that are routinely placed during these procedures, so no additional interventions will be done in acquiring the tissue and blood for this study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with a supsicion for vestibular schwannoma on an MRI for which surgery was indicated (approximately 10 per year in Maastricht).

Description

Inclusion Criteria:

  • MRI with suspicion for vestibular schwannoma
  • Indication for surgery in the skull base committee
  • 18 years or older

Exclusion Criteria:

  • Refusal to participate
  • Younger than 18 years

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Feasibility
Time Frame: 10 years
Feasibility to create organoids from schwannoma tumour tissue and make a "living" biobank of these tissues in the laboratory to study the resistance mechanisms towards treatments.
10 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Phenotype
Time Frame: 10 years
Comparing the phenotypical profile of the vestibular schwannoma organoid to the phenotypical profile of the original tumour.
10 years
Genetic
Time Frame: 10 years
Comparing the genetic profile of the vestibular schwannoma organoid to the genetic profile of the original tumour.
10 years
Epigenetic
Time Frame: 10 years
Comparing the epigenetic profile of the vestibular schwannoma organoid to the epigenetic profile of the original tumour.
10 years
Proteomic
Time Frame: 10 years
Comparing the proteomic profile of the vestibular schwannoma organoid to the proteomic profile of the original tumour.
10 years
Transcriptomic
Time Frame: 10 years
Comparing the transcriptomic profile of the vestibular schwannoma organoid to the transcriptomic profile of the original tumour.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2020

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
