Neural Correlates of Real World Spatial Navigation in Humans
Recruiting
The purpose of this study is to understand the neural mechanisms that support real world spatial navigation in humans using deep brain recordings and stimulation during virtual reality (VR), augmented reality, and real world memory tasks. We will determine the cognitive (i.e., memory) and behavioral (i.e., body, head, eye position and movement) factors that modulate deep brain activity and the consequent effects of memory-enhancing deep brain stimulation.

Oral Pyridoxal 5'-Phosphate for the Treatment of Patients With PNPO Deficiency
Recruiting
The proposed clinical study is intended to evaluate oral P5P for the treatment of patients confirmed to have Pyridox(am)ine 5'-Phosphate Oxidase (PNPO) deficiency via genetic analysis. There is an unmet clinical need for pharmaceutical grade P5P, as to date none has been made commercially available. Patients will receive pharmaceutical grade P5P according to their normal oral P5P dosing regimen, as previously established by their physicians.

Staged Complete Revascularization for Coronary Artery Disease vs Medical Management Alone in Patients With AS Undergoing Transcatheter Aortic Valve Replacement
Recruiting
Patients undergoing transcatheter aortic valve replacement (TAVR) often have concomitant coronary artery disease (CAD) which may adversely affect prognosis. There is uncertainty about the benefits and the optimal timing of revascularization for such patients. There is currently clinical equipoise regarding the management of concomitant CAD in patients undergoing TAVR. Some centers perform routine revascularization with percutaneous coronary intervention (PCI) (either before or after TAVR), while... Read More

Safety and Efficacy of IMC-F106C as a Single Agent and in Combination With Checkpoint Inhibitors
Recruiting
Brenetafusp (IMC-F106C) is an immune-mobilizing monoclonal T cell receptor against cancer (ImmTAC ®) designed for the treatment of cancers positive for the tumor-associated antigen PRAME. This is a first-in-human trial designed to evaluate the safety and efficacy of brenetafusp in adult participants who have the appropriate HLA-A2 tissue marker and whose cancer is positive for PRAME.
