Safety, Pharmacokinetics and Preliminary Efficacy Study of CFZ533 in Patients With Lupus Nephritis.

A Randomized, Placebo-controlled, Patient and Investigator Blinded, Study Investigating the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Multiple Doses of CFZ533 in Patients With Moderately Active Proliferative Lupus Nephritis

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.

Study Overview

• Status: Completed
• Conditions: Lupus Nephritis
• Intervention / Treatment: Drug: CFZ533; Drug: Placebo

Detailed Description

This was 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 was followed by a 24-week safety follow-up period.The duration of the study (including the screening period) for each patient was approximately 53 weeks. The investigational drug or placebo was administered on top of standard of care therapy for lupus nephritis.

Patients were screened within 29 days of the first study drug infusion. Eligibility was confirmed at the baseline visit within one week before the first dose. Eligible patients were assigned a randomization number and receive the intravenous infusion within 3 days of baseline visit.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 75 years (Adult, Older Adult)
• Accepts Healthy Volunteers: No

Description

Key Inclusion Criteria:

• Men and women with systemic lupus erythematosus (SLE) aged ≥ 18 years and ≤ 75 years at screening, fulfilling at least 4 out of 11 criteria for SLE as defined by the American College of Rheumatology (Tan at al 1982, revised by Hochberg 1997)
• Subjects must have a body mass index (BMI) within the range of 18 - 40 kg/m2 at screening visit
• Histological diagnosis of proliferative lupus nephritis World Health Organization (WHO) ISN/RPS (Weening et al 2004) Class III or IV within 5 years of screening
• Presence of antinuclear autoantibody (ANA titer ≥ 1:80) at screening
• Morning UPCR ≥ 0.5 at screening visit and baseline visit

• At least one of the following:

  1. low complement level (C3 ˂ 0.9 g/L) or (C4 ˂ 0.1 g/L), and/or
  2. elevated anti-dsDNA (≥ 30 IU/mL), and/or
  3. urine sediment consistent with active proliferative LN such as presence of cellular (granular or red blood cell) casts or hematuria ( ˃5 red blood cells per high power field) if other causes such as menstrual bleeding are excluded
• Patient must have sufficient kidney function as estimated by eGFR ˃ 30mL/min/1.73 m2 at screening and baseline visits (Levey et al 2009)
• Patient must have active disease as defined by proteinuria and additional symptoms as above despite standard of care therapy for LN as considered appropriate by the treating physician (e.g., corticosteroids and/or immunosuppressive or immunomodulatory treatments such as mycophenolate, azathioprine, methotrexate or hydroxychloroquine). For guidance, see published guidelines such as Bertsias et all 2012 and Hahn et al 2012.
• Women of childbearing potential (defined as all women physiologically capable of becoming pregnant) must use highly effective methods of contraception during dosing and until study completion.

Key Exclusion Criteria:

• Any glomerulonephritis other than WHO Class III or IV lupus nephritis. Patients with proliferative nephritis (Class III or IV) who, in addition, have overlapping histological signs for other glomerulonephritis, e.g., Class V, are eligible at the investigator´s discretion.
• Hypoalbuminemia (serum albumin of less than 2.0 g/dL)
