Trial Summary

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications. Please consult with the study team for guidance.

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

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What data supports the idea that Satralizumab for Thyroid Eye Disease is an effective treatment?

The available research does not provide any data on the effectiveness of Satralizumab for treating Thyroid Eye Disease. Instead, the research focuses on other treatments like alemtuzumab and teprotumumab for this condition. Therefore, there is no evidence from the provided information to support the idea that Satralizumab is effective for Thyroid Eye Disease. ^{1 2 3 4 5}

What safety data exists for Satralizumab in treating Thyroid Eye Disease?

The provided research does not contain safety data for Satralizumab (also known as Enspryng, SA-237, sapelizumab, satralizumab-mwge) in the treatment of Thyroid Eye Disease. The studies focus on Teprotumumab and Tocilizumab, which are different treatments for the same condition. ^{1 4 5 6 7}

Is the drug Satralizumab a promising treatment for Thyroid Eye Disease?

There is no information available in the provided research articles about Satralizumab being a promising treatment for Thyroid Eye Disease. The articles focus on other treatments like Teprotumumab. ^{2 4 8 9 10}

How does the drug Satralizumab differ from other treatments for thyroid eye disease?

Satralizumab is unique because it is primarily used for conditions like neuromyelitis optica spectrum disorder and works by targeting the interleukin-6 receptor, which is different from teprotumumab, the main drug for thyroid eye disease that targets the insulin-like growth factor 1 receptor (IGF-1R). This difference in mechanism of action may offer a novel approach to treating thyroid eye disease. ^{2 4 8 9 10}

What is the purpose of this trial?

This trial is testing an injectable medicine called satralizumab for people with thyroid eye disease. The medicine works by blocking a protein that causes inflammation, which can help reduce swelling and discomfort in the eyes. The study aims to see how safe and effective this treatment is for these patients.

Findings from Research

In a study of 18 patients with thyroid eye disease who did not respond to multiple steroid treatments, Tocilizumab significantly improved disease activity, as shown by a mean reduction of 5.89 points in the Clinical Activity Score (CAS).

Tocilizumab also led to a substantial decrease in thyroid-stimulating immunoglobulin (TSI) levels by 76.18% and improved symptoms such as proptosis and extraocular motility, with no severe side effects reported.

Alemtuzumab-induced thyroid eye disease (AI-TED) can present with greater severity compared to conventional thyroid eye disease (TED), as indicated by an average clinical activity score of 3.3 among 16 patients studied, with some experiencing scores as high as 5.0 during active phases.

AI-TED may develop several months after the onset of Graves' disease, highlighting the need for healthcare providers to monitor patients for potential severe TED following treatment with alemtuzumab.

Alemtuzumab-Induced Thyroid Eye Disease: A Comprehensive Case Series and Review of the Literature. Nirmalan, A., Blecher, N., Hyder, S., et al.[2023]

In a study of 162 multiple sclerosis patients treated with alemtuzumab, 44% developed thyroid dysfunction, primarily Graves' disease, with 16% referred for thyroid eye disease (TED) evaluation.

Some patients experienced severe TED requiring systemic immunosuppression, highlighting the need for regular monitoring and early referral to ophthalmology, especially for those with elevated TSH-receptor antibody levels.

In a study involving 51 patients with thyroid eye disease (TED), teprotumumab was found to be highly effective, with 89.2% of previously placebo-treated patients responding positively after receiving the treatment, showing a significant reduction in proptosis (eye bulging).

No new safety concerns were identified during the study, although mild hearing impairment was reported in some cases; this suggests that teprotumumab is a safe option for patients with TED, even those with longer disease durations.

Teprotumumab Efficacy, Safety, and Durability in Longer-Duration Thyroid Eye Disease and Re-treatment: OPTIC-X Study. Douglas, RS., Kahaly, GJ., Ugradar, S., et al.[2022]

In a study of 22 patients receiving teprotumumab for thyroid eye disease, 38.6% of ears showed hearing loss that met criteria for ototoxicity, particularly affecting high and middle frequencies.

Older patients were more likely to experience hearing loss after treatment, highlighting the need for regular audiometric testing to monitor hearing function during teprotumumab therapy.

Frequency and Patterns of Hearing Dysfunction in Patients Treated with Teprotumumab. Keen, JA., Correa, T., Pham, C., et al.[2023]

In a study of 27 patients treated with teprotumumab for thyroid eye disease, 81.5% developed new otologic symptoms, with tinnitus and ear fullness being the most common, but only 45.5% of those with hearing loss experienced symptom resolution after treatment.

Teprotumumab was associated with sensorineural hearing loss in 5 out of 6 patients tested, and a prior history of hearing loss was identified as a significant risk factor, highlighting the need for careful monitoring and screening for hearing issues in patients undergoing this treatment.

In a study of 131 patients with thyroid eye disease treated with teprotumumab, 77% experienced significant improvement in proptosis, indicating the drug's efficacy in reducing eye bulging associated with the condition.

While 81.7% of patients reported adverse events, most were mild and reversible; however, serious adverse events occurred in some cases, leading to treatment discontinuation in 12.2% of patients, highlighting the need for careful monitoring and patient education regarding potential risks.

Teprotumumab-Related Adverse Events in Thyroid Eye Disease: A Multi-Center Study. Shah, SA., Amarikwa, L., Sears, CM., et al.[2023]

In a study of nine patients with chronic thyroid eye disease (TED) and low clinical activity scores, treatment with teprotumumab resulted in a significant average reduction of 4.0 mm in proptosis (eye bulging) immediately after treatment, indicating its efficacy.

Despite some reported side effects, such as myalgias and hair thinning, teprotumumab appears to be a promising treatment option for patients with chronic TED, as evidenced by sustained proptosis reduction observed in follow-up assessments.

Teprotumumab for chronic thyroid eye disease. Ozzello, DJ., Dallalzadeh, LO., Liu, CY.[2022]

Teprotumumab significantly reduces proptosis (eye bulging) and inflammation in patients with chronic Thyroid Eye Disease (TED), with an average reduction of 3.5 mm in proptosis after treatment.

In a study of 31 patients who received an average of 7 infusions, 67% of those with diplopia (double vision) experienced a significant improvement, and there was a notable reduction in both muscle and fat tissue volume in the orbits.

Teprotumumab for the treatment of chronic thyroid eye disease. Ugradar, S., Kang, J., Kossler, AL., et al.[2022]

Teprotumumab, an IGF-1R inhibitor approved for thyroid eye disease (TED), has shown effectiveness in improving symptoms like proptosis and diplopia even in patients with long-standing disease or those who have not responded to previous treatments.

Recent reports suggest that teprotumumab can benefit patients regardless of disease duration or inflammation markers, indicating its potential as a versatile treatment option for TED.
