简要总结
This is an open-label, multicenter study to characterize the safety and efficacy of the human anti-CD19 antibody MOR00208 in adult patients with relapsed/refractory non-Hodgkin's lymphoma (NHL) who have received at least 1 prior therapy containing rituximab (at least once).
详细描述
The study enrols patients from four different NHL subtypes: follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL) and other indolent NHL (iNHL). The study will employ a two-stage design where the decision to further enrol any NHL subtype in stage 2 will depend on best responses after two or three cycles in stage 1.
