Confocal Laser Endomicroscopy for Brain Tumors
Study Purpose
The prognosis of glioblastoma patients highly depends on resection extent. Various strategies have been introduced to overcome the dilemma of intraoperative tumor identification. In gastroenterology, confocal laser endomicroscopy (CLE) allows precise differentiation of tumor tissue from surrounding mucosa in various diseases. Combining high-definition white light endoscopy with CLE significantly increases sensitivity and specificity compared with the sole application of high-definition white light endoscopy. CLE was recently introduced to neurosurgical applications. Although still in an early stage of clinical application, this technique has proven to be capable of differentiating various tumor entities in animal models as well as human tissue samples. CLE allows visualization of the underlying tissue on a microscopic scale, receiving information on the microstructure as well as cellular components. However, the clinical importance of this technique for its application in neurosurgery will be demonstrated in this clinical trial.

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. |

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. |
NCT04280952 |
|
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. |
