Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of the study is to investigate whether add-on treatment of ATG-Fresenius S to standard steroid therapy has a beneficial effect on response to therapy defined as Clinical Activity Score (CAS) and Clinical Severity Score (CSS).;Secondary Objective: The secondary objectives of the study are the assessment of the safety and further efficacy parameters in terms of T-cell subpopulations, cytokines, specific and unspecific autoantibodies, thyroid-related hormones, thyroid sonography, glycosaminoglycans, quality of life and requirement of additional treatment for GO.;Primary end point(s): The primary endpoint is the response to therapy at Week 12 vs. Week 0 after commencement of therapy. Response to treatment is defined as clinically relevant improvement of major objective ophthalmic evaluation parameters in at least one eye, which are: • Decrease in Clinical Activity Score (CAS) by >= 2 points at Week 12 compared to Week 0. • Decrease in Clinical Severity Score (CSS) by >= 2 points at Week 12 compared to Week 0.
