Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age ≥ 18 years old, regardless of gender;
  • Patients who plan to undergo brain lesion tissue resection surgery or have preoperative clinical diagnosis of gliomas and plan to undergo biopsy;
  • Patients with clinical diagnosis of initial solitary gliomas, or initial solitary intracranial masses or initial non occupying lesions that do not exclude gliomas (such as intracranial metastatic lesions, intracranial infectious lesions, intracranial demyelinating lesions, central nervous system lymphoma, etc.), who have not received radiotherapy or chemotherapy in the past based on their medical history;
  • The patient or their guardian can understand the research purpose, demonstrate sufficient compliance with the trial protocol, and sign an informed consent form;
  • It is possible to obtain tissue samples with a length diameter greater than 0.2cm. Patients diagnosed with initial solitary glioma should take core or marginal tissue, while patients diagnosed with initial single intracranial mass or initial non mass lesions but maybe with gliomas should be taken core tissue.

About this study

Official title: Evaluate the Effectiveness and Safety of the Raman IVD Analyzer for Intraoperative Glioma Diagnosis, Using Samples From Brain Resection Tissue (Prospective, Multicenter, Blind Evaluation, Single Group Target Value Method)

Compare the data obtained from the Raman analyzer and paraffin pathology examination on the same external brain tissue sample. Evaluate the effectiveness and safety of the Raman analyzer for intraoperative diagnosis gliomas of brain resection tissue samples, using paraffin pathological examination results as clinical reference standards.

Read the detailed description

Based on statistical calculations,108 positive samples and 148 negative samples will be included in the trial in all trial centers. Compare the results between the Raman analyzer and the paraffin pathological. And calculate the sensitivity, the specificity, and other indicators of Raman analyzer.

During surgery, core or marginal tissue samples were taken from subjects. The test samples size:0.2cm<length diameter ≤ 2cm. The sample testing result is based on the Raman test points. Then take the same tissue sample for paraffin pathological diagnosis.

Statistical description of all data, including baseline data, all efficacy indicators, and all safety data. The measurement data give the mean, standard deviation, minimum, maximum, median,25 quantile and 75 quantile; Provide frequency and composition ratio for counting data. The baseline data was analyzed using the Full Analysis Set (FAS); The effectiveness analysis adopts FAS and PPS; The security analysis uses the Security Dataset (SS).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Paraffin pathological diagnosisDiagnostic test

    Also called Raman analyzer diagnosis

    Perform two diagnostic methods on the same sample

Study groupRoleWhat they receive
Perform two different tests on the same sampleOtherThe same sample is diagnosed using a Raman analyzer firstly and then diagnosed by paraffin pathology.
Receives: Diagnostic Test: Paraffin pathological diagnosis

What is being measured

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

  1. Sensitivity of the Raman analyzer in detecting gliomar

    Among the samples determined by paraffin pathology as gliomas, the percentage of samples detected by Raman analyzer as gliomas.

    Measured: Through study completion, an average of 1 year

  2. Specificity of the Raman analyzer in detecting gliomar

    Among the samples determined by paraffin pathology as non gliomas, the percentage of samples detected by the Raman analyzer as non gliomas.

    Measured: Through study completion, an average of 1 year

Secondary outcomes (6)
  1. Using the paraffin test results as a reference, calculate the accuracy of the Raman analyzer in detecting gliomar

    The proportion of tissue samples with consistent results between Raman analyzer detection and paraffin pathological diagnosis.

    Measured: Through study completion, an average of 1 year

  2. Positive predictive value of the Raman analyzer in detecting gliomar

    The percentage of samples diagnosed with glioma by paraffin pathology in the samples detected as glioma by Raman analyzer

    Measured: Through study completion, an average of 1 year

  3. Negative predictive value of Raman analyzer in detecting gliomar

    The percentage of samples diagnosed with non glioma by paraffin pathology in the samples detected as non glioma by Raman analyzer

    Measured: Through study completion, an average of 1 year

  4. Kappa coefficient

    Kappa coefficient≥0.75 indicates high consistency; 0.75>Kappa coefficient≥0.4, considered consistent; If the Kappa coefficient is less than 0.4, it is considered inconsistent.

    Measured: Through study completion, an average of 1 year

  5. The Raman analyzer usability evaluation

    Use Evaluation Form

    Measured: Through study completion, an average of 1 year

  6. Time consumption for the Raman analyzer in detecting gliomar

    Time required from emitting laser to completing single point detection

    Measured: Through study completion, an average of 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Paraffin pathological diagnosis in people with Glioma, run by Beijing Tiantan Hospital.

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 5 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 13 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Tao Jiang, MD and PhD (+86 10 67021832, taojiang1964@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of the Raman analyzer in detecting gliomar (time frame: Through study completion, an average of 1 year). 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?
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 13 Jun 2023.
