      ·Third Genmab-created product approved by the U.S. FDA

Genmab A/S (Nasdaq: GMAB) announced today that the U.S. Food and Drug Administration (U.S. FDA) has granted approval to Horizon Therapeutics (Nasdaq: HZNP) for the use of teprotumumab, under the trade name TEPEZZA™ (teprotumumab-trbw), for the treatment of Thyroid Eye Disease (TED). TEPEZZA, the first and only U.S. FDA-approved medicine for the treatment of TED, was developed by and is manufactured by Horizon, completing a long development program that began when Genmab created the molecule nearly two decades ago.
Horizon submitted the Biologics License Application for teprotumumab, which received Priority Review, Orphan Drug, Fast Track and Breakthrough Therapy designations from the FDA. Teprotumumab was created by Genmab under a collaboration with Roche and development of the product is now being conducted by Horizon under a license from Roche. Under the terms of Genmab’s agreement with Roche, Genmab will receive mid-single digit royalties on sales of TEPEZZA.

“We would like to congratulate Horizon on this exciting approval, and we are very pleased that patients in the United States living with thyroid eye disease, a vision-threatening autoimmune condition, will now have this important new treatment option,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. “We also believe that this approval, the third for a Genmab-created product following Arzerra® and DARZALEX®, reflects our company’s proven track record in improving the lives of patients by creating breakthrough innovative antibody products.”   

For more information about TEPEZZA and TED, please see the press release issued by Horizon Therapeutics.

About Thyroid Eye Disease
TED, which is also known as Graves’ orbitopathy, is a rare vision threatening rare autoimmune disease associated with thyroid disease that affects the eyes including the eye muscles, eyelids, tear glands and fatty tissues behind the eye. Common symptoms of TED include proptosis (eye bulging), diplopia (double vision), misalignment of the eyes, blurred vision, irreversible disfigurement and vision loss. The disease causes serious damage as it progresses, and in some cases can lead to blindness.
