Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)

After subject has completed the trial through the safety FU period or has withdrawn early, standard treatment should be administered. Subjects who complete 24-week treatment period will be offered participation in a Long-Term Extension trial, which will be conducted under a separate CTP. The placebo arm of this trial will be switched over to the 150 mg dose of atacicept while the subjects in the treatment arms will remain on their original respective doses of atacicept when enrolled in the LTE.
