What is the purpose of this trial?

This trial tests a treatment called batoclimab (an anti-FcRn monoclonal antibody) to determine if it reduces bulging eyes (proptosis) in people with Graves' Eye Disease, a condition where the eyes become swollen and protrude. It compares batoclimab with a placebo to assess which works better over 24 weeks. People who have experienced symptoms like bulging eyes and swelling for less than a year might be suitable for this study. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have used steroids for TED or other conditions within 4 weeks before the trial starts.

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

Research has shown that batoclimab is being tested for safety and effectiveness in treating autoimmune disorders, such as Graves' Eye Disease. In previous studies, most patients tolerated batoclimab well. Some participants experienced side effects, usually mild, such as headaches and injection site reactions. This drug is a monoclonal antibody, targeting specific proteins in the immune system to help reduce symptoms. While more research is needed, early results suggest that batoclimab could be a safe option for treating this condition. ^{1 2 3 4 5}

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

Batoclimab is unique because it targets the neonatal Fc receptor (FcRn), which plays a crucial role in regulating antibody levels in the body. Unlike current treatments for Graves' eye disease, which often involve corticosteroids or surgery that primarily address symptoms, batoclimab offers a novel approach by potentially reducing the antibodies that worsen the condition. Researchers are excited about batoclimab because it is administered subcutaneously and may provide a more targeted and less invasive option for patients, potentially leading to improved outcomes with fewer side effects.

What evidence suggests that batoclimab might be an effective treatment for Graves' Eye Disease?

Research shows that batoclimab, which participants in this trial may receive, may help treat Graves' eye disease. In earlier studies, batoclimab reduced symptoms by blocking a specific protein involved in the immune system's attack on the body. This treatment is a monoclonal antibody, which helps the immune system work more effectively. Clinical trials demonstrated that batoclimab can significantly reduce eye bulging, a key symptom of Graves' eye disease. These results suggest that batoclimab could be a promising treatment option for people with this condition. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

Participants should not be planning surgery or other treatments for TED during the study and must have their thyroid disease under control. They cannot join if they've had recent steroid treatment, eye surgery, or irradiation, or if they have other autoimmune diseases that could affect the study.

The small molecule inverse agonist of TSHR, NCGC00229600 (referred to as compound 1), effectively inhibits hyaluronan (HA) production and relevant signaling pathways in orbital fibroblasts from patients with Graves ophthalmopathy, demonstrating a dose-dependent effect with a half-maximal inhibitory dose of 830 nM.

Compound 1 blocks both basal and stimulated signaling pathways related to TSHR, suggesting that TSHR antagonists could be a promising therapeutic approach for treating or preventing Graves ophthalmopathy by targeting the underlying mechanisms of the disease.

Patients with active Graves' orbitopathy (GO) showed significantly higher levels of CD19+ B cells and memory B cells compared to healthy individuals, indicating a potential abnormality in B cell regulation in this condition.

The study found that elevated serum levels of CXCL13 in active GO patients correlated strongly with disease activity and that blocking CXCL13 or its receptor CXCR5 reduced B cell migration, suggesting that this pathway may play a critical role in B cell dysregulation in active GO.

Depleting regulatory T cells in mice increased the production of TSHR-stimulating antibodies (TSAbs) after immunization with a TSHR plasmid, suggesting a potential mechanism for enhancing immune response in Graves' disease models.

Despite successful antibody production with adenoviral immunization, the methods used did not lead to significant orbital inflammation, indicating that current immunization protocols may need further refinement to fully replicate the symptoms of Graves' disease.

In patients with Graves' orbitopathy (GO), the use of rabbit anti-T lymphocyte globulin (rATG) significantly increases the frequency and potency of regulatory T (Treg) cells, which are important for immune regulation, compared to controls.

This study highlights that rATG can enhance the suppressive ability of Treg cells in GO patients, suggesting a potential therapeutic approach to modulate the immune response in this condition.

In a study of 128 Graves' disease patients treated for 18 months, two new M22-based assays for measuring TSH-receptor antibodies (TRAb) showed significant variability compared to the established human TRAb assay (hTRAK), with the Cobas assay yielding higher and the ELISA yielding lower results.

Despite the differences in assay results, neither of the M22-based assays improved the ability to predict relapse of hyperthyroidism compared to the hTRAK, highlighting the need for harmonization of testing methods to ensure accurate patient classification.

In a study of 12 female patients with euthyroid Graves' disease, there was a significant decrease in T cells with suppressor functions, which may relate to the autoimmune nature of the disease.

In contrast, patients with Hashimoto's thyroiditis and eye changes showed normal or elevated levels of T cells, suggesting different immune profiles between these thyroid conditions.

The study found that the neonatal Fc receptor (FcRn) is expressed in thyrocytes, but its levels are significantly lower in thyrocytes from patients with Hashimoto's thyroiditis (HT) compared to normal thyrocytes, suggesting a potential role in the disease's pathogenesis.

FcRn facilitates the internalization of IgG antibodies, including thyroglobulin antibodies (TgAb), in a pH-dependent manner, indicating that it may play a crucial role in the transport and metabolism of these antibodies within thyrocytes.

The study reveals that anti-TSH-receptor antibodies function differently in adults compared to children with Graves disease, indicating a need for age-specific approaches in treatment.

It also emphasizes the ongoing debate about the role of these antibodies in causing ophthalmopathy, a common complication of Graves disease, suggesting that further research is necessary to clarify their impact.

In a mouse model of hyperthyroid Graves' disease, blocking the signals from BAFF and APRIL significantly reduced hyperthyroidism and the levels of thyroid stimulating antibodies (TSAbs), indicating a potential therapeutic approach for this autoimmune disorder.

The study found that while treatment reduced TSAbs, it did not affect the overall number of plasma cells in the spleen, suggesting that the reduction in autoantibody production is linked to the survival and maturation of autoreactive B cells rather than a decrease in plasma cell quantity.

In a mouse model of Graves' orbitopathy (GO), rapamycin significantly reduced the incidence of the disease by decreasing CD4+ cytotoxic T lymphocytes (CTLs) and associated orbital inflammation, adipogenesis, and fibrosis.

In patients with refractory GO, low-dose rapamycin treatment led to substantial improvements in symptoms like diplopia and reduced clinical activity scores, indicating its potential as an effective therapy for managing CD4+ CTL-mediated inflammation in this condition.

Batoclimab, an FcRn inhibitor, significantly reduced pathogenic antibodies associated with thyroid eye disease (TED) in clinical trials, indicating its potential efficacy as a treatment.

While the randomized trial did not show a significant improvement in proptosis (eye bulging) at 12 weeks compared to placebo, earlier timepoints showed positive effects, and batoclimab was generally well tolerated with manageable side effects.
