Watch Raymond Douglas, MD, PhD, oculoplastic surgeon and Clinical Study investigator of TEPEZZA, discuss details about side effects

Read transcript

Dr. Raymond Douglas: I'm Dr. Raymond Douglas. I'm a professor of ophthalmology at Cedars-Sinai Medical Center and also in private practice in Beverly Hills. I am an oculoplastic and orbital surgeon. I spend most of my time dealing with and trying to help patients with Thyroid Eye Disease and other orbital problems.

I was also the investigator on phase two and the co-principal investigator on phase three for the clinical trial looking at teprotumumab for Thyroid Eye Disease.

The most common side effects that were observed with TEPEZZA were muscle spasms. There were also other symptoms, including diarrhea, and there was also mild hair loss, and this was all over the body, and wasn't subject to one particular location.

For example, there was some thinning of scalp hair, but many patients also noted that their body hair became thinner during the course of TEPEZZA.

Hearing impairment was also noted with TEPEZZA. This was relatively mild to moderate for the patients who reported it.

One thing to consider in use of TEPEZZA is if you have a history of inflammatory bowel disease. TEPEZZA could make inflammatory bowel disease worse or the symptoms of that disease worse. It would be good to have the disease under control prior to initiation of TEPEZZA, and to certainly review the risk and benefits with your physician.

TEPEZZA can cause an increase in blood sugar, so anyone who has diabetes or may be even pre-diabetic where this is followed with their physician, should consult their physician prior to taking TEPEZZA to know and to follow their blood glucose levels throughout treatment.

Typically, TEPEZZA infusions were very well tolerated in the clinical trial. There were three patients who had infusion reactions. These were relatively mild and well controlled, and there were no anaphylactic reactions that occurred during treatment with TEPEZZA.
