Primary Outcome Measures

Name	Time	Method
Main Objective: - Response rate at week 24: comparison of the combination treatment of anti-thyroid drug and selenium vs. anti-thyroid monotherapy (compared to baseline).<br>Response rate is defined by euthyroidism:<br>normal fT3, fT4 and TSH and negative TSH-R-Ab.<br><br>- Relapse rate at week 36 (in both groups):<br>Relapse rate is defined by change of thyroid related hormones and -antibodies (TSH, fT3, fT4, TSH-R-Ab) compared to week 24.;Secondary Objective: - Safety of the combination treatment of anti-thyroid drug and selenium.<br>Safety is defined by change of liver values (Bilirubin, ALT, AST, ?GT, AP) and WBC.<br>Safety will be determined on the week 0, 4, 12 and 24.;Primary end point(s): Response rate & Relapse rate;Timepoint(s) of evaluation of this end point: week 24 & week 36
