Confocal Laser Endomicroscopy (CLE) During Medically Induced Neurosurgery in Craniobasal and Glioma Tumours (Cleopatra)

February 5, 2019 updated by: Charalampaki, Cleopatra, M.D.

Adjoint Intra-operative Confocal Laser Endomicroscopy (CLE) to Present Tissue on the Cellular Level in Defined Lesions of the Central Nervous System (CNS) During Medically Induced Neurosurgery in Subcranial Tumors and Glioma

Purpose of the study is to answer the question whether confocal laser endomicroscopy (CLE, also named 'optical biopsy') might improve the results of medically necessary neurosurgery to prove practicability, safety and harmlessness of CLE during neurosurgical procedures

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In patients requiring neurosurgical oncological Intervention using endoscopic devices, a mini laser probe will be administered through the endoscopic device to characterize in vivo the tissue by thousandfold magnification down to the cellular level (so-called optical biopsy). Magnification is presented to the neurosurgeon in time to better differentiate between healthy and pathological tissue. Post-surgery results of in-vivo Differentiation will then be compared to histocytopathological findings.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

patients suffering from either subcranial Tumors or cerebral gliomata

Description

Inclusion Criteria:

  • patients administered to the department of neurosurgery requiring neurosurgery due to either diagnosed gliomata (40 patients) or diagnosed subcranial tumors adjacent to or already invading neuronal structures (20 patients)
  • patients having given informed consent

Exclusion Criteria:

  • severe concomitant diseases probably negatively influencing the participation in this clinical trial
  • cardial infarction or stroke within the preceding 12 months
  • Treatment resistant hypertonus (systolic blood pressure >200 mmHg or diastolic blood pressure >120 mmHg or a combination of both
  • Pulmonic diseases that might result in an advanced risk for anesthetic measurements
  • Patients being vaccinated with live vaccines (14 days Prior) or contra Influenza (7 days Prior) to start of the study
  • All concomitant findings that might increase in the eyes of the investigator the risk of participation

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
Time Frame
post-surgery comparison of in-vivo tissue characterization with ex-vivo histocytopathology
Time Frame: duration of hospital stay, an expected average of 7 days
duration of hospital stay, an expected average of 7 days

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
Time Frame
proof of complete removal of pathologic tissue within healthy tissue
Time Frame: during surgical procedure, an expected average time of three hours
during surgical procedure, an expected average time of three hours
optimal tumour remission or reduction after 3 months post-surgery proven by respective diagnostic measurements
Time Frame: 3 months post surgery
3 months post surgery
Composite measure of missing iatrogenic damage of healthy neuronal structures and preservation of functionality of healthy tissue
Time Frame: individual post-surgery controls, an expected average of up to 7 days
individual post-surgery controls, an expected average of up to 7 days

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

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.
December 1, 2015

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.
