Impact of iMRI on the Extent of Resection in Patients With Newly Diagnosed Glioblastomas
Study Purpose
Standard treatment of glioblastomas (GBMs) consists of microsurgical resection followed by concomitant chemoradiation. The extent of resection is one of the most important prognostic factors with significant influence on the survival of patients. State of the art technique to achieve the most radical resection possible in conventional surgery is fluorescence-guidance with 5-aminolevulinic acid (5-ALA). If available, intraoperative MRI (iMRI)-guided tumor resection enables an intraoperative resection control and subsequent continuation of surgery if contrast enhancing tumor remnants are found. Therefore a more radical resection and longer survival of patients might be possible. To date no comparison of these two leading technologies for GBM-surgery is available to identify the best surgical therapy of this fatal disease and to justify significant healthcare-economic differences between both technologies. Goal of this study is to assess the value of iMRI guidance in the resection of GBMs in comparison to conventional 5-ALA microsurgery. Primary endpoint is the number of total resections (no residual contrast enhancement) in the postoperative MRI (T1+CM within 48 hours after surgery) in each group. Secondary endpoints are perioperative clinical data, progression free survival, patients' clinical condition and overall survival. The study design was chosen to be a parallel-group approach to compare iMRI and 5-ALA centers (n=13) to exclude possible bias which might be found by randomizing patients within individual iMRI centers and to have surgeons with the most experience possible in use of each respective technology.

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. |
NCT02379572 |
|
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. |
