Design outcomes

Primary

MeasureTime frame
Main Objective: This study has 2 parts. The primary objective of Part I of this study is to evaluate the safety and tolerability of 3 months of treatment with 50 mg BT063 versus placebo in subjects with SLE. The primary objective of Part II of this study is to evaluate the safety and tolerability of either 25 mg, 50, mg or 100 mg BT063 versus placebo in subjects with SLE. The dose level for Part II will be determined based on an interim analysis conducted after the last subject of Part I has completed the treatment.;Secondary Objective: Secondary objectives for both parts of the study are to: •Evaluate the efficacy of 3 months of treatment with BT063 versus placebo as assessed by various disease activity indices including subject-reported outcomes •Determine the pharmacokinetics (PK) of BT063 • Compare the pharmacodynamics (PD) of BT063 and placebo on various PD markers including biomarkers •Determine the immunogenicity of BT063 ;Primary end point(s): Primary - Safety •Incidence of Adverse events (Including SAEs and AEs leading to discontinuation) from Baseline through End of Trial Visit (Week 14) •Changes from baseline through End of Trial Visit (Week 14) in: oPhysical examinations oVital signs oECGs oSafety laboratory parameters (full blood count including white differential count, clinical chemistry, thyroid hormones, urinalysis, and faecal occult blood test) oDevelopment of anti-drug antibodies against BT063 (anti-BT063) oImmunological status of potential viral and bacterial infections (HBV, HCV, HIV, tetanus, diphtheria tuberculosis) oEBV / CMV Serology o Premature withdrawals;Timepoint(s) of evaluation of this end point: From Baseline through End of Trial Visit (Week 14)

Secondary

MeasureTime frame
Secondary end point(s): Secondary –Efficacy 1.Fifty percent improvement of swollen/tender joints or 50% improvement in CLASI Activity score at week14 and week 28, depending on which was the more severe manifestation at baseline. 2.Percent changes in SLEDAI-2K scores from baseline to week 14 and at week 28 3.Flare rate and severity at week 14 and week 28 based on BILAG index A or B (flare is defined as the presence of 1 or more new BILAG A scores or 2 or more new BILAG B scores.) 4.Time to first flare 5.Number of patients requiring an increase in oral glucocorticosteroid dose before week 14 6.Physician’s Global Assessment, Functional Assessment of Chronic Illness Therapy – Fatigue (FACIT-F) and SF-36v2 Physical Component Score (PCS) at week 14 and week 28 7.ECLAM at week 14 and week 28;Timepoint(s) of evaluation of this end point: Points: 1, 2, 3, 6, 7: Week 14 and week 28 Point: 4: Time to first flare Point: 5: before week 14
