Clinical Trial Summary

The primary objective of this study is to evaluate the efficacy of a 200 micrograms (mcg) dose of CEP-33457 compared with placebo in participants with active systemic lupus erythematosus (SLE) as assessed by the proportion of participants achieving a combined clinical response using the SLE responder index (SRI) at Week 24.

Description:

The study consisted of a 2-week screening period (visit 1), a 20-week treatment period beginning with a baseline visit in which randomization was completed and study drug treatment began (visits 2 through 7), and a final assessment was performed 4 weeks after the last dose of study drug (visit 8 [week 24 or early termination]). Participants were randomized to receive either CEP-33457 or placebo subcutaneously (SC) every 4 weeks. Plasma samples for measurement of study drug concentration were collected in a subset of participants and study drug was administered at each study visit until the final visit. The dose of background steroid medication may have been increased, if needed, to treat the participant for minor fluctuations in lupus disease activity. One interim analysis was conducted when at least 80 participants completed Week 12 or had been withdrawn from the study. Participants who completed the treatment period returned to the study center 4 weeks after the last dose had been administered for final procedures and assessments. Final procedures and assessments for participants who withdrew from the study before 20 weeks of treatment were performed at the last visit. Final procedures and assessments for participants who participated in the study beyond week 24 were to be performed at the next regularly scheduled visit. Participants who complete the study will be eligible for participation in the 12-month open-label study (study C33457/3075; herein referred to as study 3075) to assess continued effectiveness and safety of the CEP-33457 treatment.

Secondary	Number of Participants Achieving a BILAG 2004 Clinical Response	The BILAG 2004 is a validated objective and subjective global measure of the disease activity of SLE based on the physician intention to treat. It includes 97 clinical and laboratory items to evaluate SLE disease activity in 9 organ systems; each organ system is assigned a score displayed as a grade from A to E, as follows: A=very active disease; B=participant needs increase in treatment for moderately active disease; C=stable or mild disease; D=previous organ involvement but no current disease activity; and E=no current disease activity and the organ system has never been involved. BILAG 2004 clinical response was defined as having an improvement in at least 1 category from a B score at baseline to a C or D score with no worsening in any other category from baseline.	Weeks 4, 8, 12, 16, 20, and 24
Secondary	Number of Participants Achieving a Physician Global Assessment (PhGA) Response	The PhGA was completed by the physician using a 3 inch VAS labeled from 0=none to 3=severe. The PhGA response was defined as having no worsening in PhGA (with worsening defined as an increase in PhGA of more than 0.30 inch from baseline).	Weeks 4, 8, 12, 16, 20, and 24
Secondary	Number of Participants Achieving a Patient's Global Assessment (PtGA) Response	The PhGA was completed by the participant using a 3 inch VAS labeled from 0=none to 3=severe. The PtGA response was defined as having no worsening in PtGA (with worsening defined as an increase in PtGA of more than 0.30 inch from baseline).	Weeks 4, 8, 12, 16, 20, and 24
Secondary	Change From Baseline in the Medical Outcome Survey Short-Form 36 (SF-36) Patient-Reported Questionnaire For Physical Component Summary (PCS) Score at Weeks 12 and 24	The SF-36 questionnaire has 36 questions composing the scale that represent 8 domains: 1) physical functioning, role physical, 2) bodily pain, 3) general health, 4) vitality, 5) social functioning, 6) role, 7) emotional, and 8) mental health. The scores for the 8 domains were combined into two summary scores: the physical component summary (PCS) score and the mental component summary (MCS) score. Items 1 to 4 primarily contribute to the PCS score of the SF-36. Items 5-8 primarily contribute to the MCS score of the SF-36. Scores on each item were summed and averaged (range: 0=worst to 100=best). Higher scores represent better health status and functional ability.	Baseline, Week 12, Week 24
Secondary	Change From Baseline in the Medical Outcome Survey SF-36 Patient-Reported Questionnaire For Mental Component Summary (MCS) Score at Weeks 12 and 24	The SF-36 questionnaire has 36 questions composing the scale that represent 8 domains: 1) physical functioning, role physical, 2) bodily pain, 3) general health, 4) vitality, 5) social functioning, 6) role, 7) emotional, and 8) mental health. The scores for the 8 domains were combined into two summary scores: the physical component summary (PCS) score and the mental component summary (MCS) score. Items 1 to 4 primarily contribute to the PCS score of the SF-36. Items 5-8 primarily contribute to the MCS score of the SF-36. Scores on each item were summed and averaged (range: 0=worst to 100=best). Higher scores represent better health status and functional ability.	Baseline, Week 12, Week 24
Secondary	Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) Damage Index	SLICC/ACR score or damage index is a measure of cumulative damage due to SLE.
