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 patients with thyroid eye disease (TED). This clinical trial will evaluate the safety, tolerability and pharmacokinetics (the concentration of drug in the blood over time) of VRDN-001 in healthy volunteers and in patients with TED. Study participants with TED will also be evaluated over time for changes in their signs and symptoms of TED compared to their baseline measurements.

Official Title

A Multiple Ascending Dose (MAD) Safety, Tolerability and Efficacy Study of VRDN 001, a Humanized Monoclonal Antibody Directed Against the IGF-1 Receptor, in Normal Healthy Volunteers (NHVs) and Subjects With Thyroid Eye Disease (TED)
