Vestibular Schwannoma Organoids

Get Involved

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years and Over
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05786144
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
