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

RGX-314 Gene Therapy Administered in the Suprachoroidal Space for Participants With Neovascular Age-Related Macular Degeneration (nAMD) (AAVIATE)
Recruiting
RGX-314 is being developed as a potential novel one-time gene therapy treatment for the treatment of neovascular (wet) age related macular degeneration (wet AMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-VEGF therapies have significantly changed the landscape for tre... Read More

Optune Delivered Electric Field Therapy and Bevacizumab in Treating Patients With Recurrent or Progressive Grade 2 or 3 Meningioma
Recruiting
The purpose of this research study is to determine the effects bevacizumab (the study drug) combined with Optune (the study device) tumor treatment field therapy has on meningiomas. Bevacizumab is considered investigational because the US Food and Drug Administration (FDA) has not approved its use for the treatment of meningiomas. The study drug is a medication that blocks the growth of new blood vessels. It is thought that the study drug may interfere with the growth of new blood vessels and th... Read More
