Key Factors Driving the Growth of the Graves Ophthalmopathy Market 

• Rising Prevalence of Graves' Disease and Thyroid Eye Disease: The increasing incidence of autoimmune thyroid disorders, particularly Graves' disease, is expanding the patient pool at risk of developing Graves' ophthalmopathy. Improved diagnosis and longer patient survival are further contributing to market growth.
• Advances in Precision Medicine and Personalized Treatment: Improved understanding of the immunological mechanisms underlying Graves' ophthalmopathy is enabling the development of targeted treatment strategies. Personalized approaches are expected to enhance efficacy while reducing treatment-related adverse effects.
• Entry of Viridian's LUMVOA: The recent approval of LUMVOA has further intensified the competition in the Graves ophthalmopathy market. As the first approved therapy with clinical labeling covering both active and chronic TED, LUMVOA expands the addressable patient population beyond currently treated active cases.
• Rise in Clinical Trial Activities: The dynamics of the Graves ophthalmopathy market are expected to change in the coming years, owing to the launch of emerging therapies such as Elegrobart (VRDN-003) (Viridian Therapeutics), Linsitinib (Sling Therapeutics), AMG 732 (Amgen), Lonigutamab (Alumis), ENSPRYNG (satralizumab, RG6168) (Roche), and others.

According to Aparna Thakur, Project Manager of Forecasting at DelveInsight, among approved therapies, TEPEZZA is expected to remain the leading revenue contributor due to its proven efficacy in reducing proptosis and its status as the only disease-specific approved treatment for Graves' ophthalmopathy. However, the anticipated entry of late- to mid-stage pipeline candidates, including elegrobart (VRDN-003), satralizumab (RG6168), and linsitinib, is expected to intensify market competition and drive a transition toward more convenient subcutaneous and oral targeted therapies throughout the forecast period.

Graves Ophthalmopathy Market Analysis

• The treatment paradigm for Graves' ophthalmopathy has evolved considerably, moving beyond symptomatic management and surgical intervention toward targeted immunomodulatory therapies. 
• Standard treatment for active disease primarily involves high-dose intravenous corticosteroids, including methylprednisolone. For patients with an inadequate response to conventional therapy, off-label biologic agents such as Tocilizumab and Rituximab are frequently considered, despite lacking specific regulatory approval for thyroid eye disease.
• A major advancement in the field was the approval of Teprotumumab (TEPEZZA) by Amgen, the first targeted therapy specifically indicated for TED. By inhibiting the insulin-like growth factor-1 receptor (IGF-1R), Teprotumumab has demonstrated significant improvements in proptosis and diplopia, transforming the treatment landscape.
• Further progress was achieved in June 2026, when the FDA approved LUMVOA (veligrotug-vvze), developed by Viridian Therapeutics, for the treatment of thyroid eye disease. 
• The approval was granted under the FDA's Priority Review program and was supported by positive results from the pivotal Phase III THRIVE trial in active TED and the THRIVE-2 trial in chronic TED.
• The Graves' ophthalmopathy pipeline continues to expand, reflecting growing interest in novel targeted therapies. Several investigational candidates are advancing through clinical development, including elegrobart from Viridian Therapeutics, satralizumab from Roche, linsitinib from Sling Therapeutics, and others, highlighting an increasingly competitive therapeutic landscape.

Graves Ophthalmopathy Competitive Landscape

Some of the Graves ophthalmopathy drugs under development include Elegrobart (VRDN-003) (Viridian Therapeutics), Linsitinib (Sling Therapeutics), AMG 732 (Amgen), Lonigutamab (Alumis), ENSPRYNG (satralizumab, RG6168) (Roche), and others.

Viridian Therapeutics' Elegrobart is an investigational monoclonal antibody being developed by Viridian Therapeutics for the treatment of thyroid eye disease. The therapy is designed to inhibit the insulin-like growth factor-1 receptor (IGF-1R), a well-established driver of TED pathogenesis. Viridian is advancing Elegrobart as a potential best-in-class subcutaneous anti-IGF-1R treatment that can be self-administered at home using a low-volume autoinjector, with dosing intervals of either once every four weeks or once every eight weeks. According to the company's SEC filing, a Biologics License Application (BLA) submission is expected in the first quarter of 2027.

Sling Therapeutics' Linsitinib is an investigational oral therapy being developed to reduce the treatment burden associated with TED for patients, caregivers, and healthcare providers. It is the first and only oral small-molecule candidate to demonstrate both statistically and clinically meaningful efficacy in TED. The drug exerts its therapeutic effect by blocking IGF-1R, the only clinically validated target in TED and the mechanism underlying currently approved FDA therapies for the disease. Since activation of IGF-1R contributes to inflammation and the development of proptosis, inhibiting this pathway may help alleviate key manifestations of TED. Linsitinib also has an extensive clinical safety record, having been evaluated in more than 900 patients across 15 clinical studies spanning multiple disease indications.

Amgen's AMG 732 is a monoclonal antibody that targets the insulin-like growth factor-1 receptor (IGF-1R) and is currently under investigation as a potential treatment for thyroid eye disease.

Alumis' Lonigutamab is a next-generation, humanized IgG1 monoclonal antibody that targets the insulin-like growth factor 1 receptor (IGF-1R) and has been developed for subcutaneous administration. In contrast to other IGF-1R-targeting therapies, it recognizes a unique receptor epitope, promoting rapid internalization and degradation of the IGF-1R complex. Its subcutaneous formulation supports more convenient long-term treatment and may improve the depth and durability of clinical responses in patients with chronic conditions. As the first subcutaneous anti-IGF-1R therapy to demonstrate efficacy in thyroid eye disease comparable to intravenously administered therapies, lonigutamab has the potential to combine the proven effectiveness of IGF-1R inhibition with a convenient dosing regimen and a potentially best-in-class safety profile. Alumis is also evaluating strategic alternatives for the future development and commercialization of the lonigutamab program.

The anticipated launch of these emerging therapies are poised to transform the Graves ophthalmopathy market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the Graves ophthalmopathy market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth.
