Eligibility Criteria
Inclusion Criteria:
- Subjects with CD20 positive DLBCL or grade 3b follicular lymphoma (FL) at original diagnosis.
- Refractory to, or relapsed following, first-line treatment with rituximab combined with anthracycline- or anthracenedione-based chemotherapy as defined by the protocol.
- CT with involvement of 2 or more clearly demarcated lesions/ nodes with a long axis > 1.5 cm and short axis >= 1.0cm or 1 clearly demarcated lesion/ node with a long axis > 2.0 cm and short axis >= 1.0 cm.
- Baseline FDG-PET scans must demonstrate positive lesions compatible with CT defined anatomical tumor sites.
- Age 18 yrs or older.
- ECOG performance status of 0, 1 or 2.
- Eligible for high dose chemotherapy and ASCT.
- Resolution of toxicities from first-line therapy to a grade that in the opinion of the investigator does not contraindicate study participation.
- Signed written informed consent.
Exclusion Criteria:
- Previous cancer therapy for lymphoma, with the exception of first-line rituximab/ anthracycline- or anthracenedione-based chemotherapy, monotherapy rituximab prior to or combined with first-line chemotherapy, as maintenance therapy, and radiotherapy in a limited field or as a part of the first-line treatment plan.
- Any anti-cancer therapy, except limited field radiotherapy, within 2 weeks prior to start of study therapy.
- Planned post-randomization chronic glucocorticoid use (limited acute use is allowed and defined by the protocol) unless administered as therapy for mild COPD or asthma.

- Prior treatment with anti-CD20 monoclonal antibodies with the exception of rituximab.
- Abnormal/ inadequate WBC count, liver, and kidney function.
- Pregnant or lactating women or female patients of child-bearing potential (or male patients with such partners) not willing to use adequate contraception during and up to 1 year following dosing completion.
