E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint consists of a composite endpoint concerning meaningful improvement across 2 of 3 Sjögren’s syndrome disease domains: oral, ocular, and laboratory tests. Oral improvement will be defined as ≥20% in the patient’s assessment of dry eyes (on a 100 mm VAS) or ≥20% improvement in total unstimulated salivary flow. Ocular improvement will be difined as ≥20% improvement in either the patient’s assessment of dry eyes by VAS or the results of the Schirmer test without anaesthetic. Laboratory improvement will be defined as ≥20% improvement in the serum IgG or the ESR. |
