The sponsor electively terminated the study because the risk mitigation measures, deemed necessary after an unforeseen safety event, could not be effectively implemented within this protocol while maintaining study timelines within a reasonable time frame.

Study summary:

This study will evaluate atacicept's effects in subjects who have lupus nephritis, at least 2 g/day of protein in the urine, and are already taking mycophenolate mofetil. The evaluations will include the concentrations of atacicept in the blood, the effects of atacicept on immunoglobulins (antibodies), and any side effects. The first subjects will be given a low dose. Following periodic reviews of the trial data, subsequent subjects are planned to receive one of 2 progressively higher doses of atacicept.
