The mechanism of action of teprotumumab in patients with TED has not been fully characterized. Teprotumumab-trbw binds to IGF-1R and blocks its activation and signaling.

IGF-1R, insulin-like growth factor-1 receptor.

Not all signs of TED may be visible, so it’s important to ask your patients if they’re experiencing new or changing symptoms. If they are, consider a TED treatment that works at a root cause of the disease.3,9,11

Risk factors can include: smoking (past or present), radioactive iodine treatment, advanced age, female sex, poorly controlled hyper-/ hypothyroidism, and family history of TED or autoimmune diseases9,10,12

Different diseases can sometimes be misdiagnosed
due to similar symptoms1,2,13

Hi. My name is Dr. Lisa Mihora. And I am an oculoplastics surgeon in Phoenix, Arizona. Distinguishing Thyroid Eye Disease and Graves’ disease is important. They’re often linked, but they are two different entities. And Thyroid Eye Disease can actually present before, during, or after the diagnosis of Graves’ disease.

Thyroid Eye Disease can present in patients who are euthyroid, hyperthyroid, or even hypothyroid. And because Thyroid Eye Disease is a separate and distinct disease from Graves’, treating Graves’ does not address the pathophysiology or symptomatology of Thyroid Eye Disease.

In Graves’ disease auto-antibodies target the thyrotropin receptor, which thereby triggers hyperthyroidism. Whereas in Thyroid Eye Disease, we have additional auto antigens and antibodies that are involved.

The understanding of the mechanism of Thyroid Eye Disease has changed, now that insulin-like growth factor-1 receptor, or IGF-1 receptor, has been identified.

We now know that orbital fibroblasts, which are up-regulated in Thyroid Eye Disease, are key drivers of the pathophysiology of Thyroid Eye Disease. The T-cells and fibroblasts activate, and the inflammatory response and cascade has begun.

And the pathophysiology can translate into the signs and symptoms of Thyroid Eye Disease.

Once the fibroblasts are activated, they can cause severe inflammation and over-expansion of tissues, muscle, and the fat cells that are located behind the eye.

Because this is a fixed bony orbit, this can lead to different clinical manifestations.

Inflammation can occur, as well as foreign body sensation. A patient may have excessive tearing or dry eye. There can be conjunctival or eyelid redness, as well as swelling. A patient may have orbital pain, chemosis, proptosis, or bulging eye, and diplopia, or double vision.

Because there are so many different signs and symptoms that a patient can present with, educating patients, as well as our providers, means that we can hone in on the diagnosis earlier, and potentially treat earlier.

The goal of treating Thyroid Eye Disease early, in order to help combat the symptoms a patient may have, is a team approach. A team approach between endocrinology, and ophthalmology, or oculoplastics.

Endocrinology has a very unique role, in that they specialize in treating the autoimmune disorder and the endocrine dysfunctions, such as Graves’ disease and refer early to the ophthalmologist or oculoplastic surgeon, in order to monitor the eye symptomatology.

Ophthalmologists or oculoplastic surgeons can often be the first to diagnose Thyroid Eye Disease patients. A baseline eye exam is conducted. And the patient’s Thyroid Eye Disease is evaluated.

I do co-manage patients with endocrinologists. And I find it very helpful when the endocrinologist now refers a patient early. That way, we can potentially start treatment, and start exams, and start the discussion, as early as possible.

I think that this dual approach to a patient gives a patient the best information and the best team approach, so that both aspects of the Thyroid Eye Disease can be effectively treated and managed.

TED is a debilitating and potentially disfiguring disease1-3

Based on an online QOL assessment survey of 100 patients including all levels of TED severity.23

Ask your patients about how the burden of TED effects them, including signs and symptoms, emotional well-being, and daily activity performance

Diagnosing Thyroid Eye Disease (TED)

There are a number of diagnostic protocols and tools available to aid in a TED diagnosis. Radiographic imaging with CT or MRI can be helpful. Grading systems include the EUGOGO, VISA, and GO-QOL scales. The Clinical Activity Score (CAS) may be used to identify the signs and symptoms of inflammation characteristic of TED8,9,18

CAS

CAS measurements may be required
for treatment approval

  • The score at each efficacy assessment is the number of all items present24

Clinical Activity Score

  • CAS is a 7-point composite score measuring spontaneous orbital pain, gaze-evoked orbital pain, eyelid swelling, eyelid erythema, conjunctival redness, chemosis, and inflammation of caruncle or plica. A lower score indicates fewer symptoms but does not take symptom severity into account. The CAS is a composite score with equal weighting of a number of factors. However, the factors may not be of equal clinical weight to patients or to physicians treating these patients24,25

Ask your patients if they are currently experiencing or have
ever experienced the following:

  • Spontaneous orbital pain
  • Gaze-evoked orbital pain
  • Eyelid swelling
  • Eyelid erythema
  • Conjunctival redness
  • Chemosis
  • Inflammation of caruncle or plica

Symptoms may not always be noticeable during a baseline examination; at follow-up visits it is important to ask your patients if they are experiencing any new or changing symptoms.3,9,11

A multidisciplinary team is optimal to reduce the
burden of TED4,9,11,26,27

  • TED is best evaluated and co-managed by an endocrinologist, eye care provider, and TED Specialist. A TED Specialist can be an eye specialist provider or an endocrinologist, but this varies depending on each ecosystem and/or neighboring specialties9,28

INDICATION

TEPEZZA is indicated for the treatment of Thyroid Eye Disease regardless of Thyroid Eye Disease activity or duration.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Infusion Reactions: TEPEZZA may cause infusion reactions. Infusion reactions have been reported in approximately 4% of patients treated with TEPEZZA. Reported infusion reactions have usually been mild or moderate in severity. Signs and symptoms may include transient increases in blood pressure, feeling hot, tachycardia, dyspnea, headache, and muscular pain. Infusion reactions may occur during an infusion or within 1.5 hours after an infusion. In patients who experience an infusion reaction, consideration should be given to premedicating with an antihistamine, antipyretic, or corticosteroid and/or administering all subsequent infusions at a slower infusion rate.

Preexisting Inflammatory Bowel Disease: TEPEZZA may cause an exacerbation of preexisting inflammatory bowel disease (IBD). Monitor patients with IBD for flare of disease. If IBD exacerbation is suspected, consider discontinuation of TEPEZZA.

Hyperglycemia: Increased blood glucose or hyperglycemia may occur in patients treated with TEPEZZA. In clinical trials, 10% of patients (two-thirds of whom had preexisting diabetes or impaired glucose tolerance) experienced hyperglycemia. Hyperglycemic events should be controlled with medications for glycemic control, if necessary. Assess patients for elevated blood glucose and symptoms of hyperglycemia prior to infusion and continue to monitor while on treatment with TEPEZZA. Ensure patients with hyperglycemia or preexisting diabetes are under appropriate glycemic control before and while receiving TEPEZZA.

Hearing Impairment Including Hearing Loss: TEPEZZA may cause severe hearing impairment including hearing loss, which in some cases may be permanent. Assess patients’ hearing before, during, and after treatment with TEPEZZA and consider the benefit-risk of treatment with patients.

ADVERSE REACTIONS

The most common adverse reactions (incidence ≥5% and greater than placebo) are muscle spasm, nausea, alopecia, diarrhea, fatigue, hyperglycemia, hearing impairment, dysgeusia, headache, dry skin, weight decreased, nail disorders, and menstrual disorders.
