Pilot Study of Preoperative Intestinal Training Using Antegrade Ileostomy Infusion
Recruiting
This research study is being conducted to study the effect of infusing your contents from your ostomy bag back into your intestine to re-train them prior to the ostomy takedown operation, which is a surgery to reverse your ostomy to put your intestine back together. Because your intestine past the ostomy hasn't seen any intestinal content for several weeks to months before the takedown operation, it is no longer used to handling the daily work of processing intestinal content and will take time...

A Study to Determine the Biodistribution, Safety, and Tolerability of a Microdose of Radiolabeled BIIB080 Co-administered With BIIB080 in Healthy Adults
Recruiting
In this study, researchers will learn more about a study drug called BIIB080. BIIB080 is currently a drug under investigation for treatment of Alzheimer's disease. The main question researchers are trying to answer in this study is how radiolabeled BIIB080 distributes in the brain and spinal cord. To help answer this question, researchers will use positron emission tomography (PET) scanner that can detect radiolabeled BIIB080 after a single injection of a small dose of radiolabeled BIIB080 (\[89...

Study of BB-031 in Acute Ischemic Stroke Patients (RAISE)
Recruiting
The purpose of this study is to evaluate the safety and tolerability of ascending doses (Part A) and selected doses (Part B) of BB-031 in acute ischemic stroke patients presenting within 24 hours of stroke onset. Participants will be randomized to receive one dose of either the investigational drug or placebo and will be followed for 90 days. A total of 156 patients are planned in this study.

Advancing Transplantation Outcomes in Children
Recruiting
This is a pediatric kidney transplant study comparing the safety and efficacy of an immunosuppressive regimen of belatacept and sirolimus to tacrolimus and Mycophenolate Mofetil (MMF). Two hundred participants will be randomized (1:1) to one of two groups within 24 hours following the transplant procedure. The duration of the study from time of transplant to the primary endpoint is 12-24 months.

Non-Inferiority Trial of TrIGR for PTSD
Recruiting
Trauma-related guilt is common and impairing among trauma survivors, particularly among Veterans with posttraumatic stress disorder (PTSD). The investigators' work shows that a brief treatment targeting trauma-related guilt, Trauma Informed Guilt Reduction Therapy (TrIGR), can reduce guilt and PTSD and depression symptoms. Whether TrIGR is no less effective than longer, more resource heavy PTSD treatments disseminated by by VA, like cognitive processing therapy (CPT), is the next critical questi... Read More

The Biomarkers in the Hyperbaric Oxygen Brain Injury Treatment Trial (BioHOBIT)
Recruiting
There are no therapeutic agents that have been shown to improve outcomes from severe traumatic brain injury (TBI). Critical barriers to progress in developing treatments for severe TBI are the lack of: 1) monitoring biomarkers for assessing individual patient response to treatment; 2) predictive biomarkers for identifying patients likely to benefit from a promising intervention. Currently, clinical examination remains the fundamental tool for monitoring severe TBI patients and for subject select... Read More
