Summary

Graves' disease is an autoimmune thyroid disorder characterized by the production of autoantibodies against the thyroid-stimulating hormone receptor (TRAb), leading to excessive thyroid hormone secretion and systemic manifestations. A subset of patients develop refractory disease, failing to achieve durable remission despite prolonged antithyroid therapy.

This study aims to evaluate the safety and efficacy of HN2301, an in vivo CAR-T therapy in which host T lymphocytes are engineered and transformed to functional CAR-T cells via CD8 antibody-coated LNP delivery of CD19 CAR-mRNA. Participants with refractory Graves' disease will receive three to five administrations of HN2301 and will be regularly monitored for changes in thyroid function, TRAb levels, clinical response, and treatment-related adverse events. The study will provide preliminary evidence on whether HN2301 can induce sustained remission of refractory Graves' disease.
