Filter by:The investigational drug, VRDN-001, is a monoclonal antibody that inhibits the activity of a cell surface receptor called insulin-like growth factor-1 receptor (IGF-1R). Inhibition of IGF-1R may help to reduce the inflammation and associated tissue swelling that occurs in patients with thyroid eye disease (TED). The primary objective of this clinical trial is to evaluate the safety and tolerability of VRDN-001 in patients with TED.
To investigate corneal endothelial cell layer damage by specular microscopy in patients with thyroid eye disease
This study is a randomized, controlled, multi-center clinical study, the purpose is to evaluate the efficacy and safety of rapamycin combined with methylprednisolone in the treatment of moderate to severe active GO. GO patients with moderate to severe activity were selected as the research objects, and the screening period was 1 week. Eligible and well-informed subjects were randomly assigned 1:1 to the experimental group (rapamycin + methylprednisolone) or the control group (methylprednisolone group). The control group was given methylprednisolone pulse 500 mg/time once a week for 6 weeks + 250 mg/time once a week for 6 weeks, and the experimental group was given rapamycin 2 mg/day orally for 24 weeks on the basis of methylprednisolone pulse therapy. The follow-up period was from 25th to 36th week. Before treatment, 1 week after treatment, 6 weeks, 12 weeks, 24 weeks, and 36 weeks, visits were conducted to evaluate the improvement and safety evaluation of patients' GO eye activity, severity, and quality of life. At the end of the 1st week and the 12th week, the blood concentration of rapamycin was measured.
This is a single-arm, prospective, open-label, Phase II study that explored the efficacy and safety of SHR-1314 in active moderate to severe Graves' Orbitopathy. The study consists of a 6-week screening period, a 16-week treatment period, and a 12-week follow-up period. Eighteen adult patients with active moderate to severe Graves' Orbitopathy will be enrolled. Eligible subjects will receive SHR-1314 subcutaneously. The primary endpoint was the proptosis responder rate and will be evaluated at 16weeks.
Graves' orbitopathy (GO) is the most common extra-thyroidal manifestation of Graves' disease (GD). Based on its clinical signs and symptoms, GO is graded as mild, moderate-to-severe, or severe, and active or inactive, the latter feature being established on a 5/7-scale score named Clinical Activity Score (CAS). The European Group on Graves Orbitopathy (EUGOGO) has recently formulated and published up-to-date guidelines for the management of GO, according to which high dose intravenous (iv) glucocorticoids (GC) (ivGC) is the first line treatment for moderate-to-severe and active GO. A protective effect of atorvastatin on the development of GO in patients with GD has been reported, based on which we recently conducted a phase II, randomized, open label clinical trial and found that atorvastatin improves the response of GO to ivGCs in hypercholesterolemic patients. The effect was unrelated to cholesterol levels, suggesting that it may be the consequence of a direct action of atorvastatin. To investigate this issue further and to introduce atorvastatin in the clinical practice, we designed the present Phase III, double-blinded, multicenter, randomized, adaptive, superiority, no profit, clinical trial to evaluate the effects of atorvastatin on Graves' Orbitopathy (GO) in patients with moderate-to-severe and active GO subjected to intravenous glucocorticoid therapy, regardless of cholesterol levels.
The purpose of this study is to evaluate supramaximal rectus recession for strabismus in Grave's Ophthalmopathy
The purpose of this study is to determine whether combination of orbital compression surgery with strabismus surgery is better than strabismus surgery after orbital compression surgery in the treatment of moderate-to-severe thyroid associated ophthalmopathy
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, open-label, randomized clinical trial is to evaluate the efficacy of Sirolimus in patients with moderately severe, active GO. 54 patients (27 per group) will be randomized into two groups, A and B. Patients in group A will receive Sirolimus for 12 weeks. Patients in group B will receive methylprendnisolone for 12 weeks. The primary objective of the study is the response of GO at 24 weeks based on a composite evaluation. The secondary Objectives will be: 1) the response of of GO at 12, 36 and 48 weeks; 2) Relapse of GO at 36 and 48 weeks (worsening compared with the 24-week evaluation); 3) The reduction of proptosis at 12, 24, 36 and 48 weeks (proportion of patients with a reduction of proptosis of at least 2 mm); 4) Reduction of the GO clinical activity score (CAS) at 12, 24, 36 and 48 weeks; 5) Quality of life (Qol) at 12, 24, 36 and 48 weeks. The safety objectives will be adverse events, adverse drug reactions, unexpected adverse reaction, suspected unexpected adverse reactions and death, across the study and at 12, 24, 36 and 48 weeks.
Graves' orbitopathy (GO) is a disfiguring and disabling disease that profoundly impairs the quality of life of affected patients. High dose intravenous (iv) glucocorticoids (GC) (ivGC) is a well established, widely used treatment for active GO. The use of systemic glucocorticoids takes advantage from their immune suppressive and antiinflammatory actions, resulting in an overall beneficial effect ranging from ~35 to ~60% of patients in various studies. The intravenous route of administration has been shown to be superior to the oral route, both in terms of GO outcome and side effect profile. The combination of ivGC and orbital radiotherapy (OR) is used routinely in patients with moderate-severe, active GO, as a second-line treatment, as also recommended in the recent Guidelines published by the European Thyroid Association/European Group on Graves' Orbitopathy. Thus, the majority of studies have shown that OR increases the response rate to GC. Those studies were performed using oral GC, whereas it is not known whether OR potentiate also the effects of ivGC. The present study is aimed at determining whether OR potentiate the effects of ivGC in the treatment of moderately severe and active GO, in terms of GO outcome and quality of life. A possible extension of the study can be foreseen, aimed at investigating the very long time GO outcome.
Thyroid eye disease is an autoimmune disorder affecting approximately 50% of individuals with autoimmune thyroid diseases resulting in enlargement of ocular muscles and may lead to congestion of the eyelids and ocular surface, ocular movement restriction and double vision, and optic nerve compression and loss of vision. First line medical therapy is oral or intravenous corticosteroids (CS), which several studies have shown results in reduction of soft tissue congestion, but some studies suggesting that ocular restriction or visual loss may still occur in spite of CS therapy.i External beam radiotherapy (XRT) is second line therapy but is controversial, with some studies suggesting benefit in preventing onset of double vision or optic nerve compression while other studies suggest it has no benefit. Most proponents of XRT for TED believe that it is most effective early in the disease evolution. XRT has been shown to be a safe therapy with few side-effects, although retinopathy changes have developed in a small percentage of diabetics and its use is avoided for diabetics. Combined oral prednisone and XRT has been shown to be more effective in reducing soft tissue inflammation and motility complications than either monotherapy in two different studies. To date there have been no trials comparing combined XRT and iv CS with iv CS alone for early progressive TED to identify potential benefit in reducing the severity of motility disorders or preventing the onset of dysthyroid optic neuropathy. That is the purpose of this study.
