Filter by:The main goal of this study is to learn how teprotumumab will be processed in the body (Pharmacokinetics) subcutaneously and whether it is safe and tolerable after administration into adult patients with thyroid eye disease.
This is a multicenter, randomized, double-masked, placebo-controlled Phase II/III study in subjects with active thyroid eye disease. Approximately 114 subjects meeting study eligibility criteria will be randomly assigned to IBI311 or placebo on day 1 (D1) in a 2:1 ratio stratified by smoking status
The goal of this interventional study is to compare the effectiveness of two different glucocorticoid regimens for treatment of active moderate-to-severe Graves' orbitopathy. The main questions it aims to answer are: 1. Are the two glucocorticoid regimens similarly effective? 2. Do the two glucocorticoid regimens have similar safety profile? The patients involved are treated with one of the two glucocorticoid regimens. Their ocular status, therapeutic response and quality of life reassessed during the treatment, at its end, and 3 month later.
The purpose of the present interventional study is to assess the changes in the therapeutic response, ocular manifestations of Graves' orbitopathy and quality of life during the first year after orbital radiotherapy. The main questions it aim to answer are: 1. How effective is orbital radiotherapy used as first- or second-line treatment in patients with Graves' orbitopathy? 2. How does the quality of life changes after orbital radiotherapy? Participants have active moderate-to-severe Graves' orbitopathy and are treated with low dose fractionated orbital radiotherapy for two weeks. During the follow-up period they undergo regular ocular examinations and fill out a disease-specific questionnaire.
This study was conducted to develop an AI solution to evaluate clinical activity score (CAS) of thyroid associated orbitopathy (TAO) using periocular selfie images taken by smartphones in patients with thyroid dysfunction. An AI solution to evaluate CAS in TAO was developed in previous retrospective study using periorbital digital images taken by DSLR camera in the studio. This AI solution will be adjusted to show its best performance with periocular selfie images taken by smartphones.
The study objective is to investigate the efficacy and safety of periocular injections of methotrexate in management of patients with active moderate to severe thyroid associated orbitopathy in comparison to periocular injections of triamcinolone acetonide.
Graves' Orbitopathy (GO) is a disabling and disfiguring condition associated with Graves' Disease, due to autoimmunity against antigens expressed by the thyroid and orbital tissues, and resulting in orbital fibroblast proliferation and release of glycosaminoglycans. The current treatments available, especially glucocorticoids, are not effective in all patients. Two cases of patients with GO treated with Sirolimus have been reported with an excellent response to the drug. The rationale for the use of Sirolimus lies in its mechanisms of action. Sirolimus is able to inhibit T-cell activation as well as fibroblast proliferation. In addition, acts indirectly on the Insulin-Like Growth Factor-1 (IGF-1) pathway, and recent clinical trials have shown that a monoclonal antibody against the IGF-1 receptor (Teprotumumab) is effective in patients with GO. Thus, Sirolimus could be used in GO as monotherapy in patients with GO. The aim of the present drug vs standard treatment, observational study is to evaluate the efficacy of Sirolimus as a second-line treatment in patients with moderately severe, active GO.
To compare the efficacy of local injections of two different types of steroid (betamethasone suspension versus triamcinolone acetate) in management of patients with thyroid-related upper lid retraction either isolated or associated with proptosis.
Graves' disease is characterized by the combination of anti-TSH receptor antibodies (Thyroid-Stimulating Hormone or thyroidotropic hormone), specific to this disease, with inconsistent symptoms such as hyperthyroidism, orbitopathy, goiter, or myxedema dermatological involvement. The activation of TSH receptors (RTSH) by these antibodies (known as "TRAK") causes the secretion of thyroid hormones as well as the development of the thyroid gland, responsible for a goiter. The cellular infiltrate responsible for the goiter consists mainly of T-lymphocytes but also of activated B lymphocytes secreting TRAK. Although Graves' disease is antibody mediated, cytokine secretion by Th1 therefore seems essential to pathogenesis. The treatment of orbitopathy requires primarily euthyroidism and the discontinuation of smoking. Despite these measures, moderate to severe attacks may require immunomodulatory treatment to limit local inflammation. This treatment is currently based on a first-line corticosteroid treatment (per os or preferably by weekly intravenous infusions). In the context of inadequate response, the therapeutic strategy is not very well established since some immunosuppressive treatments targeting B-cells or T- cells have been studied but with little benefit. Many new concepts concerning immune tolerance and autoimmunity have emerged in recent years, particularly in Graves' disease, with sometimes complex cellular interactions. Certain mechanisms could occur either independently or in combination: i) modulation of T cell activation, differentiation and apoptosis; ii) inhibition of BL maturation and immunoglobulin production; iii) alteration of the balance between T helper (Th)-17 and T regulatory lymphocytes (Treg), by promoting Treg differentiation and inhibiting Th17 differentiation.
The overall objective is to investigate the efficacy, safety and tolerability of TEPEZZA® in participants with chronic (inactive) TED (thyroid eye disease). Approximately 57 participants will be enrolled. There will be a treatment period (through Week 24) and a follow up period (where TEPEZZA will not be infused).
