Clinical Trials

CREST-2: Carotid Revascularization and Medical Management for Carotid Stenosis
The purpose of CREST-2 is to compare three different methods of stroke prevention to find the safest and most effective treatment. The stroke prevention methods include intensive medical management alone compared to intensive medical management in combination with a procedure to reopen the carotid artery in your neck (called revascularization) for treatment of plaque buildup. The two procedures available in this trial are carotid endarterectomy and carotid stenting. All study participants will receive intensive medical management to help control their risk factors for stroke.

GammaTile vs. Stereotactic Radiotherapy for Newly-Diagnosed Metastatic Brain Tumors

The purpose of this study is to compare the safety and effectiveness of surgical tumor removal followed by stereotactic radiotherapy (SRT) to surgical tumor removal in conjunction with intraoperative radiation therapy using GammaTiles. A GammaTile is a collagen sponge containing four radiation seeds. After tumor removal, the tiles are placed in the tumor bed to deliver radiation to any remaining cells. Patients will be randomized to receive either intraoperative GammaTile radiotherapy or traditional radiotherapy 3-4 weeks after tumor removal (standard of care).

'Smart Socks' measure gait and balance to quantify functional improvement with spinal cord simulation (SCS)
The purpose of this prospective study is to quantify measures of gait movement and balance before and during the trial stimulation, and after permanent implantation. Assessment of gait and balance parameters in candidates that receive spinal SCS are recorded using pressure sensitive, sensor-implanted socks (Palarum PUP® Smart Socks, Cincinnati, OH). Four evaluations will be performed: 1) baseline before trial implant, 2) with SCS trial implant, 3) 3 months after permanent implant, and 4) 1 year follow-up interview. Quantifying measures of gait balance may help to inform the long term success of SCS placement for back pain.

Spinal Cord Stimulation for treatment of neuropathic pain and symptoms related to restless legs syndrome (RLS)
The purpose of this study is to evaluate patients who are scheduled to receive Spinal Cord Stimulation (SCS) for back pain, and additionally have moderate to severe Restless Legs Syndrome, to understand the amount of RLS symptom alleviation as a result of spinal cord stimulation. Spinal cord stimulation is a well-established technique for the management of chronic neuropathic pain. Patients scheduled to undergo implantation of a spinal cord stimulator for chronic low back pain that have a diagnosis of moderate to severe RLS and qualify for the study will be invited to participate.

Transforaminal Lumbar Interbody Fusion (TLIF) using Infuse™ Bone Graft and the Capstone™ Spinal System for degenerative spine disease
The purpose of this study is to evaluate the Infuse™ Bone Graft in combination with the Capstone™ Spinal System and an implantable, metal rod and screw system and autograft bone (your own bone) to see if it is safe and effective when used in a TLIF surgery. Two different amounts of the Infuse™ Bone Graft material will be tested. The Infuse™ Bone Graft is considered investigational because it has not been approved by the U.S. Food and Drug Administration (FDA) for use in a TLIF surgery. The Infuse™ Bone Graft is approved by the FDA for use in another type of spinal fusion surgery using other spinal fusion devices. Participation in the study will last between 2 and 4 years.
