BrainGate2: Feasibility Study of an Intracortical Neural Interface System for Persons With Tetraplegia

Status: Recruiting
PI: Jaimie Henderson, MD
NCT00912041
Contact: Omar Rutledge, orutledge@stanford.edu

The purpose of the first phase of the pilot clinical study of the BrainGate2 Neural Interface System is to obtain preliminary device safety information and to demonstrate the feasibility of people with tetraplegia using the System to control a computer cursor and other assistive devices with their thoughts. Another goal of the study is to determine the participants’ ability to operate communication software, such as e-mail, simply by imagining the movement of their own hand. The study is invasive and requires surgery.

Individuals with limited or no ability to use both hands due to cervical spinal cord injury, brainstem stroke, muscular dystrophy, or amyotrophic lateral sclerosis (ALS) or other motor neuron diseases are being recruited into a clinical study at Massachusetts General Hospital (MGH) and Stanford University Medical Center. Clinical trial participants must live within a three-hour drive of Boston, MA or Palo Alto, CA. Clinical trial sites at other locations may be opened in the future. The study requires a commitment of 13 months.

Stereotactic Laser Ablation for Temporal Lobe Epilepsy (SLATE)

Status: Recruiting
PI: Casey Halpern, MD
Co-PI: Gerald Grant, MD, FACS
NCT02844465

The purpose of the study is to evaluate the safety and efficacy of the Visualase MRI-guided laser ablation system for necrotization or coagulation of epileptogenic foci in patients with intractable mesial temporal lobe epilepsy.

The study will include approximately 120 adult patients with drug-resistant MTLE treated at selected epilepsy centers across the United States. After the Visualase procedure, patients will be followed for 12 months and evaluated for freedom from seizures, quality of life, adverse events, and neuropsychological outcomes.

Efficacy of Repetitive Transcranial Magnetic Stimulation for Improvement of Memory in Older Adults with TBI

Status: Recruiting
PI: Maheen Adamson, PhD
NCT: NCT03727737
Contact: Harlene GrewalHarlene.Grewal@va.gov

Many older adults with Traumatic Brain Injury (TBI) report cognitive problems that last for months or years. The most common cognitive deficits occur in the areas of verbal fluency, attention, working memory, planning, and mental flexibility.

This study will evaluate the safety, durability and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a promising non-invasive therapeutic treatment for improving memory in older adults with mild or moderate Traumatic Brain Injury (TBI) who have been experiencing residual memory or cognitive problems.

Patients aged 50-75 years with mild or moderate TBI, who are more than 6 months post-injury and currently experiencing memory or cognitive problems, are being recruited. Evaluation, treatment with rTMS, and subsequent follow up will be conducted over a 6-8 month period. In addition, advanced neuroimaging (PET MRI) will be conducted.

A Phase 1/2 Dose Escalation Study of AST-OPC1 in Subjects with Subacute Cervical Spinal Cord Injury

Status: Closed to Enrollment, Active
PI: Gary K Steinberg, MD, PhD
NCT02302157
Contact: neuroscienceclinicaltrial@stanford.edu

The purpose of this study is to evaluate the safety of 3 sequential escalating doses of AST-OPC1 administered at a single time-point between 14 and 30 days post injury, inclusively, to subjects with subacute cervical spinal cord injuries (SCI).

A Double-Blind, Controlled Phase 2 Study of the Safety and Efficacy of Modified Stem Cells (SB623) in Patients with Chronic Motor Deficit from Traumatic Brain Injury (TBI)

Status: Closed to Enrollment, Active
PI: Gary K Steinberg, MD, PhD
NCT02416492
Contact: Kathy McDonald, kmcdonl@stanford.edu

The primary purpose of the clinical study is to evaluate the clinical efficacy of intracranial administration of SB623 cells on patients with chronic motor deficit from Traumatic Brain Injury. A secondary purpose of the study is 1) to evaluate the effect of intracranial administration of SB623 cells on disability parameters and 2) to evaluate the safety and tolerability of intracranial administration of SB623 cells. Patients with stable, chronic motor deficits secondary to focal traumatic brain injury must be between 12-60 months post TBI.

A Double-Blind, Controlled Phase 2B Study of the Safety and Efficacy of Modified Stem Cells (SB623) in Patients with Chronic Motor Deficit from Ischemic Stroke

Status:Closed to Enrollment, Active
PI: Gary K Steinberg, MD, PhD
NCT02448641
Contact: Kathy McDonald, kmcdonl@stanford.edu

Controlled study of stereotactic, intracranial injection of SB623 cells in patients with fixed motor deficits from ischemic stroke. The ischemic stroke must be 6 month-60 month after injury.
