Beamion LUNG-1: A Study to Test Different Doses of Zongertinib in People With Different Types of Advanced Cancer (Solid Tumours With Changes in the HER2 Gene)
Recruiting
The study has 2 parts. The first part is open to adults with different types of advanced cancer (solid tumours with changes in the HER2 gene) for whom previous treatment was not successful. The second part is open to people with non-small cell lung cancer with a specific mutation in the HER2 gene. The purpose of the first study part is to find the highest dose of a medicine called zongertinib the participants can tolerate. Once this dose is found, it will be used in the second study part to te... Read More

Perivenous Dexamethasone Therapy: Examining Reduction of Inflammation After Thrombus Removal to Yield Benefit in Acute Femoropopliteal DVT
Recruiting
This is a study of a medical procedure that utilizes a commercially available catheter (the BullfrogĀ® Micro-Infusion Device) to locally deliver a commercially available anti-inflammatory drug (dexamethasone sodium phosphate injection) around the deep veins after DVT recanalization, where DVT symptoms were present for up to 14 days prior to recanalization. The goal of the study is to see if local anti-inflammation helps prevent re-thrombosis of the blood vessel and improvement in symptoms for up... 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

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
