Amgen·interventional·Posted Oct 2, 2017·Updated Jul 11, 2024

In Brief

A Phase 3 clinical trial evaluating Teprotumumab and Placebo for Thyroid Eye Disease and Graves' Orbitopathy. Completed, enrolled 83 participants across 14 sites in 3 countries.

Detailed Summary

The overall objective is to investigate the efficacy, tolerability, and safety of teprotumumab (a fully human monoclonal antibody \[mAb\] inhibitor of the insulin-like growth factor-1 receptor \[IGF-1R\]) administered once every 3 weeks (q3W) for 21 weeks with a final assessment at Week 24, in comparison to placebo, in the treatment of participants with moderate-to-severe active thyroid eye disease (TED).

Interventions

Teprotumumabbiological

Teprotumumab is a fully human anti-IGF-1R mAb. Teprotumumab will be provided in single-dose 20 mL glass vials as a freeze-dried powder. Each vial of teprotumumab must be reconstituted with 10 mL of water for injection. Reconstituted teprotumumab solution must be further diluted in 0.9% (w/v) sodium chloride (NaCl) solution prior to administration. Teprotumumab will be administered in 100 mL or 250 mL infusion bags (100 mL infusion bags for doses up to 1800 mg and 250 mL infusion bags for doses \> 1800 mg).

Placeboother

Placebo will consist of normal saline (0.9% NaCl) solution and will be administered in 100 mL or 250 mL infusion bags, as would be appropriate, per weight-based dosing volumes (100 mL infusion bags for doses up to 1800 mg and 250 mL infusion bags for doses \> 1800 mg).
