A Study of Andecaliximab in People With Spinal Cord Injury at Risk for Bone Growth Outside of the Normal Skeleton.

Heterotopic Ossification (HO)

This is an open-label study of andecaliximab in participants at risk of developing bone where bone should not be, such as in muscle, tendons, and other soft tissues following traumatic spinal cord injury. The goal of this study is to assess the safety of andecaliximab, how much drug is in the body over time (pharmacokinetics/PK), and how it affects the body (pharmacodynamics/PD) in participants who have had a recent traumatic spinal cord injury.

Testosterone Deficiency and Endothelial Dysfunction After Spinal Cord Injury

Spinal Cord Injuries · Endothelial Dysfunction · Testosterone Deficiency

Heart attacks and strokes are among the most common causes of premature death in individuals living with spinal cord injury (SCI) and appear to occur earlier in life. The factors that lead to the heighten and accelerated risk of heart attacks and strokes in adults living with SCI remain poorly understood. The investigators aim to uncover why this happens and find ways to prevent it. Our research focuses on how important cells which line blood vessels, called endothelial cells, function after SCI. The investigators test endothelial function in live conscious people with SCI. The investigators also study signaling molecules endothelial cells release called endothelial cell derived microvesicles (EMVs), which the investigators can measure in blood to tell us the health of endothelial cells. By using these rigorous tests of vascular function, the investigators have determined that endothelial cells appear dysfunctional after SCI. The investigators also know that many men with SCI have low testosterone levels. Our team has studied testosterone's effects on endothelial dysfunction and believe low testosterone may be contributing to endothelial dysfunction after SCI. By understanding these mechanisms, the investigators hope to improve the lives of those living with SCI and reduce their risk for heart attacks and strokes. The investigators propose to study the influence of testosterone on endothelial function by using state-of-the-art clinical and laboratory experiments to assess endothelial function in men with SCI with low and normal testosterone levels.

Sensory Motor Transformations in Human Cortex

Quadriplegia

This research study is being conducted to develop a brain controlled medical device, called a brain-machine interface. The device will provide people with a spinal cord injury some ability to control an external device such as a computer cursor or robotic limb by using their thoughts along with sensory feedback. Development of a brain-machine interface is very difficult and currently only limited technology exists in this area of neuroscience. Other studies have shown that people with high spinal cord injury still have intact brain areas capable of planning movements and grasps, but are not able to execute the movement plans. The device in this study involves implanting very fine recording electrodes into areas of the brain that are known to create arm movement plans and provide hand grasping information and sense feeling in the hand and fingers. These movement and grasp plans would then normally be sent to other regions of the brain to execute the actual movements. By tying into those pathways and sending the movement plan signals to a computer instead, the investigators can translate the movement plans into actual movements by a computer cursor or robotic limb. A key part of this study is to electrically stimulate the brain by introducing a small amount of electrical current into the electrodes in the sensory area of the brain. This will result in the sensation of touch in the hand and/or fingers. This stimulation to the brain will occur when the robotic limb touches the object, thereby allowing the brain to "feel" what the robotic arm is touching. The device being used in this study is called the Neuroport Array and is surgically implanted in the brain. This device and the implantation procedure are experimental which means that it has not been approved by the Food and Drug Administration (FDA). One Neuroport Array consists of a small grid of electrodes that will be implanted in brain tissue and a small cable that runs from the electrode grid to a small hourglass-shaped pedestal. This pedestal is designed to be attached to the skull and protrude through the scalp to allow for connection with the computer equipment. The top portion of the pedestal has a protective cover that will be in place when the pedestal is not in use. The top of this pedestal and its protective cover will be visible on the outside of the head. Three Neuroport Arrays and pedestals will be implanted in this study so three of these protective covers will be visible outside of the head. It will be possible to cover these exposed portions of the device with a hat or scarf. The investigators hope to learn how safe and effective the Neuroport array plus stimulation is in controlling computer generated images and real world objects, such as a robotic arm, using imagined movements of the arms and hands.

ARC-IM System to Manage Symptomatic Blood Pressure Instability Secondary to Chronic Spinal Cord Injury

Spinal Cord Injuries · Blood Pressure Disorders

Empower BP is a pivotal, interventional, multicenter, prospective, randomized, controlled double-blinded study to evaluate the safety and effectiveness of the ARC-IM System in managing symptomatic blood pressure instability in individuals with chronic SCI (\>1 year after SCI). The primary effectiveness outcome will be evaluated through subject-reported ADFSCI and seated blood pressure assessments at 3 months post-implant. Following a baseline screening period and the surgical implantation of the ARC-IM System, subjects will be randomized with a 2:1 ratio into an active or control arm for 3 months. All the subjects will undergo therapy activation sessions (into either Group 1: active intervention, or Group 2: intervention aimed to mimic the active intervention without the active component) within 21 days of the surgical implant and will then commence independent at-home use of ARC-IM Therapy. At the 3 Month timepoint, after all assessments are conducted, all subjects will transition to the open-label period in order to receive the active version of the ARC-IM System in an open-label fashion. All subjects will undergo therapy programming sessions following Month 3.

Role of Endothelial Function in SCI CVD Risk

Spinal Cord Injuries · Cardiovascular Diseases · Endothelial Dysfunction

Individuals with spinal cord injury have heart attacks and strokes more frequently, and much earlier in life. People with spinal cord injuries develop plaque in vessels much faster, and the reasons why are unclear. Doctors generally attributed the increased risk with weight gain and developing diabetes, but many studies have shown that even without these common factors, plaque in vessels is developing more often and faster. Endothelial cells are a single layer of cells that line all vessels in the body and plays an important role in vessel health. Damage to endothelial cells is known to lead to heart attacks and strokes. Past studies on endothelial cells of people with spinal cord injury have been unclear. The investigators have new data that these cells are unhealthy after spinal cord injury a measurement. This includes measuring endothelial health by directly altering its function using a catheter in the arm and measuring small particles in blood called endothelial microvesicles. If the project is successful, the investigators will learn important information on the health of endothelial cells after spinal cord injury. The investigators will also be able to use these markers of endothelial cell function to create treatments to improve vessel health and prevent heart attacks and strokes later in life in people with spinal cord injury.

Spinal Stimulation for Upper Extremity Recovery in the Home

Cervical Spinal Cord Injury

The purpose of this research is to evaluate the safety, feasibility, and tolerability of non-invasive spinal stimulation used in the home and/or community in combination with a functional home exercise program for the upper extremities (arm/hand function) as well as their combined impacts on changes in upper extremity function. The expected duration of participation in this study is about 31-33 hours over a 13-25-week period. Enrollees in this study will be randomly assigned to one of two groups: 1) upper extremity functional task-specific training combined with non-invasive transcutaneous spinal stimulation, or 2) waitlist control, which involves the same intervention, but with a 12-week delayed start. Participants complete initial testing (one time if in group one and three times \[at weeks 0, 8, and 12\] if in group two), 24 1-hour training sessions (2x/week in home with caregiver/companion support and 1x/week with research team in person or via video conference for 8 weeks), a post-treatment evaluation, and a final evaluation (4 weeks after post-treatment).

Endothelial Dysfunction After SCI

Spinal Cord Injuries · Endothelial Dysfunction

This study plans to learn how endothelial cells, single cell lining of blood vessels may be dysfunctional after a spinal cord injury. Endothelial dysfunction will be measured by the capacity of blood vessels to vasodilate (increase in size) and alter blood flow is lower in adults with a spinal cord injury in comparison to adults without a spinal cord injury. The mechanisms which may alter this function may be critical in reducing the risk of heart attacks and strokes in people with spinal cord injuries.
