Brief summary

ASTED (Antioxidant Supplements for TED) trial is an investigator-initiated, randomized, triple masked, clinical trial of a selected combination of vitamins and minerals versus placebo in patients with moderate to severe thyroid eye disease. The trial has a parallel-arm design.

Detailed description

Primary aim: To investigate if ASTED or as compared with placebo could affect the course of TED either by enhancing improvement or preventing worsening in patients with Moderate to severe TED thyroid eye disease (TED) based on: 1. Total eye score (NOSPECS severity score) 1 Total eye score is used to assess the severity of TED, which was calculated by multiplying each class of the NOSPECS system1 (except class 0) to its grade of severity (0-3), yielding a maximum total score of 63 and a minimum total score of 0 (the higher the number the worse the severity) The overall ophthalmic outcome is a composite score based on multiple items (Soft tissue, retraction, proptosis, diplopia, and corneal involvement); the use of a composite score circumvents the problem arising from the presence of improvement in one item and simultaneous worsening in another item. The severity score in each of the classes 1, 2, 3, and 4 will also be separately compared to evaluate the effect of different treatments on each sign. 2. Score of thyroid eye disease Quality of life questionnaire (TED-QOL) 2. Secondary outcomes measures: To compare possible change in: 1. Clinical activity score (CAS Score) 3 (7 items are scored in the beginning and 10 items are scored at 3 and 6 months) 2. Serum thyroid auto-antibodies (Anti-thyroid peroxidase (TPO), Anti-thyroglobulin) at 0, 3 and 6 months. Thyroid function test (Free T4, T3, and TSH) will be measured in all 3 visits0 3. Side effects

Interventions

DRUGMethylprednisolone + ASTED

ASTED tablet: Twice daily for 6 months Methylprednisolone: Methylprednisolone tablet of 50 and 5 mg, company….) 1mg/kg for the first 2 weeks, 0.8mg/kg for 2 weeks, 0.7 mg/kg for 2 weeks, and then tapering off the methylprednisolone in 6 weeks (total duration of 12 weeks) by 8-10 mg per week. For example, a patient with 75 kg weight will receive 75 mg for 2 weeks, 60 mg for 2 weeks, 52.5 mg for 2 weeks, and then decreasing by 8-10 mg per week for 6 weeks. The dose regiment will be written and handed to the patient on the first visit and will be monitored during the follow ups.
