How fast does Rituximab work for ITP?
Rituximab is a chimeric monoclonal antibody targeting a B-cell antigen (CD20) that has been used widely as a second line therapy for ITP with a promising response rate approaching 60% in some studies. A response is usually seen between week one to eight of therapy and could last for five years in some patients.
