MabRella Study: A Study to Evaluate the Safety of Switching From Intravenous to Subcutaneous Administration of Rituximab During First-Line Treatment for Lymphoma

This open-label, single-arm, phase IIIb study will evaluate the safety of switching from intravenous (IV) to subcutaneous (SC) administration of rituximab during first-line treatment for participants with CD20+ non-Hodgkin's follicular lymphoma (FL) or diffuse large B-cell lymphoma (DLBCL) who have already received at least one full dose of rituximab IV. Participants with FL will be given 1400 mg rituximab SC during induction therapy (once monthly for 4-7 cycles) and maintenance therapy (once every 2 months for 6-12 cycles). 1400 mg SC of rituximab will be given to participants with DLBCL once monthly for 4-7 cycles. Treatment duration is expected to last up to 7 months for participants with DLBCL and up to 32 months for participants with FL.
