Study Details
Study Description
Brief Summary
This study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary therapeutic efficacy of multiple doses of CFZ533 anti-CD40 monoclonal antibody in patients with moderately active lupus nephritis.

Phase 2 |
Detailed Description
This is a randomized, subject and investigator blind, placebo controlled multicenter study with multiple doses of CFZ533 administered by 1-hour intravenous infusion over a 24 week treatment period, as compared to matched placebo infusion. The treatment period will be followed by a 24-week safety follow-up period.The duration of the study (including the screening period) for each patient will be approximately 53 weeks. The investigational drug or placebo will be administered on top of standard of care therapy for lupus nephritis.
Patients will be screened within 29 days of the first study drug infusion. Eligibility will be confirmed at the baseline visit within one week before the first dose. Eligible patients will be assigned a randomization number and receive the intravenous infusion within 3 days of baseline visit.

Outcome Measures
Primary Outcome Measures
- Safety as assessed by adverse events [From baseline to week 49]
Number and percentage of patients with adverse events
- Renal proteinuria [From baseline to week 25]
Ratio from baseline in urinary protein creatinine ratio (UPCR) to week 25
Secondary Outcome Measures
- Urine protein creatinine ratio (UPCR) and hematuria and cellular casts [From baseline to week 49]
Ratio from baseline for urine protein creatinine ratio (UPCR) and hematuria and cellular casts to evaluate the renal effect.
- Plasma pharmacokinetics (PK) of CFZ533: the area under plasma concentration-time curve calculated to the last quantifiable concentration point (AUClast). [From baseline to week 49, pre dose and 1 hour post dose]
The following PK parameter will be determined from the plasma concentration time profile of CFZ533: AUClast: AUClast is the area under plasma concentration-time curve calculated to the last quantifiable concentration point.
