New Data Insights from the Phase 3 Teprotumumab Trial (OPTIC) to be Presented at the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) Scientific Symposium

10/08/19

 DUBLIN--(BUSINESS WIRE)--Oct. 8, 2019-- Additional results from the Phase 3 confirmatory clinical trial (OPTIC) of teprotumumab, an investigational medicine being developed by Horizon Therapeutics plc, will be presented at the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) 50th Anniversary 2019 Fall Scientific Symposium in San Francisco on Oct. 11.

The ASPORS meeting marks the first time that detailed secondary endpoint outcomes from the teprotumumab OPTIC trial related to diplopia (double vision), Graves’ Ophthalmopathy (GO) Quality of Life and clinical activity score (CAS) will be presented. CAS is a 7-point scale that quantifies the pain, redness and swelling of various eye tissues. Posters about the perceptions and burden of thyroid eye disease (TED) will also be presented.

 Presentation Details: 

“Teprotumumab Infusions Reduce Proptosis in Thyroid-Eye Disease in a Randomized, Placebo-Controlled, Clinical (OPTIC) Study: Effectiveness on Diplopia and other Secondary Outcomes”

 About Thyroid Eye Disease 

Thyroid eye disease (TED) is a serious, progressive and vision-threatening autoimmune disease with a limited window of activity that can last up to three years.1,2,3 While TED often occurs in people living with hyperthyroidism or Graves’ disease, it is a distinct disease that is caused by autoantibodies activating an IGF-1R-mediated signaling complex on cells within the orbit.4,5 This leads to a cascade of negative effects, which may cause long-term, irreversible damage. Active TED lasts for up to three years and is characterized by inflammation and tissue expansion behind the eye.1,6 As TED progresses, it causes serious damage – including proptosis (eye bulging), strabismus (misalignment of the eyes), and diplopia (double vision) – and in some cases can lead to blindness.2,7 TED has only been shown to respond to pharmacotherapy while the disease is active and inflammation is ongoing.8 Currently, patients must live with active TED until the disease becomes inactive – often left with permanent and vision-impairing consequences.1,6  

 About Teprotumumab 

Teprotumumab is a fully human monoclonal antibody (mAb) and a targeted inhibitor of the insulin-like growth factor 1 receptor (IGF-1R). By targeting the IGF-1R signal, teprotumumab reduces inflammation and prevents excessive muscle and fat cell expansion behind the eye. The U.S. Food and Drug Administration (FDA) is currently evaluating teprotumumab’s Biologics License Application (BLA) under Priority Review, a designation granted to applications for medicines that have the potential to provide significant improvements in the treatment of serious conditions. If approved, teprotumumab would be the first FDA-approved medicine for the treatment of active TED. Teprotumumab has also received Orphan Drug, Fast Track and Breakthrough Therapy designations from the FDA. The clinical development program for teprotumumab in the treatment of TED includes positive results from the Phase 3 OPTIC confirmatory clinical trial as well as positive Phase 2 results, which were published in The New England Journal of Medicine. The OPTIC trial was conducted at leading centers in the U.S., Germany and Italy, with co-principal investigators Raymond Douglas, M.D., Ph.D., Cedars-Sinai Medical Center; and George Kahaly, M.D., Ph.D., Johannes Gutenberg University Medical Center. Horizon is also conducting the OPTIC‐X extension trial to gather further insight into the long-term efficacy and safety of teprotumumab.
