A Randomized, Controlled, Safety and Tolerability Study of VRDN-001 in Participants With Thyroid Eye Disease (TED)

NCT06384547 | Completed Phase 3 Results DMC FDA Drug

• 1 other identifier: VRDN-001-303
• Study Type: interventional
• Target: 231
• Locations: 7 countries
• Sites: 50

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Number of Participants With Treatment-emergent Adverse Events (TEAEs) Through Week 15

  An adverse event (AE) was defined as any untoward medical occurrence that developed or worsened in severity during the conduct of a clinical study and did not necessarily have a causal relationship to study drug. TEAE was defined as an AE occurring on or after the day of the first dose of study medication through the end of the study. A summary of all Serious Adverse Events (SAEs) and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.

  Baseline through Week 15

Secondary Outcomes (2)

• Change From Baseline in Proptosis in the Study Eye as Measured by Exophthalmometer

  Baseline, Week 15

• Number of Participants With TEAEs Through Week 52
