What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests an investigational oral treatment called linsitinib for people with moderate to severe active Thyroid Eye Disease (TED), a condition linked to autoimmune thyroid disease that causes swelling, discomfort, and bulging of the eyes. As a Phase 3 trial, this study is designed to confirm how well linsitinib works and to continue monitoring its safety in a larger group of people.

Do I need to stop my current medications for the trial?

Some medications can be continued and others will need to be stopped. It's best to discuss this with the study doctor to understand how your medications might interact with the trial.

Is there any evidence suggesting that linsitinib is likely to be safe for humans?

Linsitinib has been studied in earlier research, including trials involving more than 800 people in a different disease area, which provided information about how the drug affects the body. It has also been evaluated in an earlier-phase study in people with Thyroid Eye Disease. Because linsitinib is still investigational and is not approved for use in any country, its full range of effects and side effects is not yet known. This Phase 3 trial is being conducted to learn more about the safety of linsitinib in people with Thyroid Eye Disease, and participants will be monitored closely throughout the study.

Why do researchers think this study treatment might be promising for Thyroid Eye Disease?

Linsitinib is designed to block a signal called the IGF-1 receptor that plays a key role in driving the eye changes in TED. Blocking this same IGF-1 receptor pathway is the basis for an existing approved TED therapy. Researchers are especially interested in linsitinib because it is taken as a simple oral pill rather than an infusion, which could make treatment easier for patients.

Are You a Good Fit for This Trial?

Adults aged 18 and older with Thyroid Eye Disease linked to Graves' disease and/or Hashimoto's thyroiditis may be able to join. Eligible participants have moderate to severe, active eye disease that was diagnosed within about the last 15 months and has a noticeable impact on daily life.They must be willing to sign the consent form and follow the study plan.

Inclusion Criteria

Are your thyroid levels currently stable and well-controlled?
Do you currently experience any of these: eyelids pulling back, red or swollen eyes, bulging eyes, or double vision?
Were you diagnosed with Thyroid Eye Disease (TED) within the past 15 months?

Exclusion Criteria

Have you ever received treatment with Tepezza (teprotumumab) or Lumvoa (veligrotug-vvze)?
Have you ever had surgery or radiation treatment for your eye socket area?
Have you ever been diagnosed with a liver condition—such as hepatitis, a fatty liver, cirrhosis, or abnormal liver blood tests?

Trial Overview

This study is testing linsitinib, an oral pill, as a possible treatment for Thyroid Eye Disease (TED). Participants will take either linsitinib or a placebo (an identical-looking pill with no active medicine) so the two can be compared. The pills are taken twice a day, about 12 hours apart, with food and a glass of water, for 24 weeks. Researchers will track how participants' eyes and overall health respond over the course of the study to understand how well linsitinib works and how safe it is.
