A Study for Cerebral Open Flow Microperfusion

Study Purpose

The purpose of this study is to evaluate the safety and feasibility of intra-operative microperfusion during a planned neurosurgical resection of diseased brain parenchyma, including either an epileptic focus requiring temporal lobectomy or a glioma. Devices used for microperfusion are Joanneum Research cerebral open flow microperfusion (OFM) catheters, push and pull tubing, and MPP102-II pump.

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.	Interventional
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.	NCT07089758
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.	N/A

Arms & Interventions

Arms

Experimental: Study Group

Patients undergoing a planned neurosurgical resection of diseased brain parenchyma.

Interventions

Device: - Cerebral open flow microperfusion

Patients will undergo intra-operative microperfusion using Joanneum Research's cerebral open flow microperfusion (OFM) catheters, push and pull tubing, and MPP102-II pump. This process utilizes a probe (catheter) inserted into the parenchyma to collect analytes of any size and polarity from the microenvironment. The microperfusion pump peristaltically pushes and pulls perfusate with no net fluid-exchange when the pump heads are set at equal flow rates. As perfusate enters the tip of the microperfusion catheter, analytes are exchanged based on a gradient between the interstitial fluid and the perfusate. The sample is then recovered via the "pull" portion of the peristaltatic microperfusion pump, enabling constant sampling volumes and preventing loss of the perfusate into the tissue. The duration is 60-80 minutes (dependent on the speed of progress resecting portions of the tumor without catheters)
