Viridian Therapeutics, Inc. (NASDAQ: VRDN), a biotechnology company advancing new treatments for patients suffering from serious diseases underserved by current therapies, today announced positive initial clinical data from the 10mg/kg cohort in its ongoing Phase 1/2 clinical trial of VRDN-001, an anti-IGF-1R antibody, in patients with active thyroid eye disease (TED). TED is a rare autoimmune disease in which the body’s own immune system attacks the tissues around and behind the eyes causing inflammation, swelling, and damage, which develops into signs and symptoms of double vision, bulging eyes, and ocular pain. The double-blind, placebo-controlled Phase 1/2 trial is evaluating two infusions of VRDN-001 administered intravenously. The inclusion and exclusion criteria and the baseline patient characteristics for this trial are similar to prior TED clinical trials. Efficacy measurements include proptosis (bulging eyes), Clinical Activity Score (CAS), and diplopia (double vision), which are the same endpoints as measured in the clinical development of Tepezza®, the only approved therapy targeting IGF-1R in patients with TED.
“TED is a severe, debilitating eye disease that threatens patients’ vision and overall quality of life,” said Raymond Douglas, M.D., Ph.D., director of the Orbital and Thyroid Eye Disease Program, Cedars-Sinai Medical Center and an investigator on the VRDN-001 trial. “In this trial, rapid and significant improvement in a broad set of efficacy measures suggests that VRDN-001 may have a differentiated profile that could offer meaningful benefits to patients.”
