Original description

The investigational drug, VRDN-001, is a monoclonal antibody that inhibits the activity of a cell surface receptor called insulin-like growth factor-1 receptor (IGF-1R). Inhibition of IGF-1R may help to reduce the inflammation and associated tissue swelling that occurs in participants with TED. The primary objective of this clinical trial is to evaluate the safety and tolerability of VRDN-001 in participants with TED.Read full original descriptionShow less
