Atacicept Phase II/III in Generalized Systemic Lupus Erythematosus
A Randomised, Double-blind, Placebo Controlled, Multicentre Prospective Dose-finding Phase II/III Study With Atacicept Given Subcutaneously to Subjects Having Recently Experienced a Flare of Systemic Lupus Erythematosus (SLE)
This study is intended to evaluate the use of atacicept compared to placebo in reducing the number of flares for people with SLE. The study is randomized and is designed to find the most effective dose of atacicept. Study medication is administered via subcutaneous (under the skin) injections, beginning with twice weekly injections for the first 4 weeks, followed by weekly doses for one year. Follow-up will continue for an additional 24 weeks.

Phase 3
Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Systemic Lupus Erythematosus, SLE
  • Drug: Atacicept 75mg
    Dose is 75mg given subcutaneously (under the skin), twice a week for 4 weeks, and then once a week for 48 weeks.
  • Drug: Atacicept 150mg

    Dose is 150mg given subcutaneously (under the skin), twice a week for 4 weeks, and then once a week for 48 weeks.

    The atacicept 150mg has been discontinued. The decision was taken following a recommendation of the Independent Data Monitoring Committee. They determined that the risk benefit profile for the patients receiving the higher dose of Atacicept was unfavorable.

  • Other: Placebo Comparator
    Placebo comparator is matched volume given subcutaneously (under the skin), twice a week for 4 weeks, and then once a week for 48 weeks.
  • Experimental: 1
    Intervention: Drug: Atacicept 75mg
  • Experimental: 2
    Intervention: Drug: Atacicept 150mg
  • Placebo Comparator: 3
