First-In-human Trial of a NovEl Soft and Stretchable Neural probE

NCT ID: NCT06673264

Last Updated: 2025-09-18

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 5 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-03-14
• Study Completion Date: 2025-08-21

Brief Summary

The goal of this interventional study is to find out the feasibility of whether the soft neural probe can be used in human brain tissue. The main questions it aims to answer are:

• Are there any problems when inserting the soft neural probe into brain tissue?
• Can the soft neural probe record electrical signals from the brain tissue?

Participants will:

• During their already scheduled brain tumor or epileptic tissue removal, have the soft neural probe inserted into the section of brain tissue that is due to be removed
• Visit the clinic for follow up after 30 days for checkups

Conditions

Feasibility of Safe Insertion and Neural Recording With a Soft Neural Probe; Brain Surgery

Eligibility Criteria

Inclusion Criteria

• Adults 18-80 years of age at the time of providing informed consent
• Capable of providing written informed consent to participate
• Willing to commit to the study evaluations and visit schedule
• Undergoing a planned surgery for brain tissue resection of either a tumor or of a epileptogenic lesion
• Adequate hepatic, renal, cardiac, and hematologic function according to the following laboratory test criteria:

• Absolute neutrophil count ≥ 1,500/mm3
• Platelet count ≥ 100,000/mm3
• Bilirubin ≤ 1.5 mg/dL
• AST and ALT ≤ 2.5 times upper limit of normal
• Creatinine ≤ 1.5 mg/dL
• Signs of previous or current ischemic cardiac disease or arrhythmia per electrocardiogram assessment
• Females of childbearing potential must have a negative serum pregnancy test and agree to use birth control measures during study treatment and for 3 months after its completion
• Must not be pregnant or nursing at study entry
• Women/men of reproductive potential must have agreed to use an effective contraceptive method

Exclusion Criteria

• Substance abuse, according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5)
• Allergy to any study materials
• Presence of any powered implantable medical device or any medical device implanted in the brain
• Weakened immune system due to presence of poorly controlled chronic diseases such as human immunodeficiency virus (seropositive for HIV 1 or 2), decompensated diabetes, decompensated chronic kidney disease, decompensated liver disease, intake of immunosuppressive medications such as high-dose corticosteroids, or a previous diagnosis of congenital or acquired immunodeficiency
• Exposure to any type of chemotherapy in the past 3 months
• Radiation therapy in the surgical area within the last year
• Delay to the base operation creates additional risk for the patient due to uncontrolled elevated ICP or emergency surgery
• Active infection, bleeding, or hematoma
• Patients with previous resection surgery in the planned surgical area
• Previous stroke in the affected tissue
• Currently high levels of inflammation as indicated by ESR, CRP, or PCT blood test
• Any concurrent medical condition or disease (e.g. uncontrolled active hypertension, uncontrolled active diabetes, or active systemic infection) that is likely to interfere with study procedures.
• Uncontrolled active infection requiring parenteral antibiotics, antivirals, or antifungals within 1 week prior to the planned neurosurgical intervention. Patients on prophylactic antibiotics or with a controlled infection within 1 week prior to the planned neurosurgical intervention are acceptable.
• Any active, serious psychiatric, medical, or other conditions/situations that, in the opinion of the Investigator, could interfere with treatment, compliance, or the ability to give informed consent.
• Any other psychological, family or geographic problem that may make compliance with the study protocol difficult.
• Life expectancy of less than 3 months.
• Major surgery within 4 weeks prior to planned neurosurgical intervention

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 80 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
