Summary: Study Comparing the Zevalin Regimen With No Further Treatment in DLBCL Patients Who Are in Complete Remission After CHOP-R

This study will treat patients with diffuse large B-cell lymphoma whose disease is in complete remission due to previous treatment with CHOP-R. Half of the patients will receive Zevalin and the other half will receive no further anti-cancer treatment. The two patient groups will be compared to determine if Zevalin given after CHOP-R therapy provides greater benefits than receiving no additional anti-cancer therapy after CHOP-R.

Inclusion Criteria:

• Histologically confirmed, Ann Arbor stage II, III or IV DLBCL according to the REAL/WHO classification (from initial diagnosis made prior to starting CHOP-R therapy)
• Central pathology review confirming the DLBCL diagnosis and CD20 positivity, and no evidence of DLBCL in bone marrow
• First-line treatment of DLBCL must have been 6 or 8 cycles of standard CHOP chemotherapy (cyclophosphamide 750 mg/m², doxorubicin 50 mg/m², vincristine 1.4 mg/m² up to a maximum of 2 mg on day 1, and at least 40 mg/m²/day prednisone on Days 1 to 5 every three weeks, with generally accepted adjustments in dose or frequency due to toxicity, patient scheduling, etc.) in combination with rituximab (375 mg/m²)
• Complete remission (CR) or unconfirmed complete remission (CRu) according to the International Workshop Response Criteria for NHL described by Cheson et al and modified for this study after first-line treatment with CHOP-R. CT scans of chest, abdomen, pelvis, and neck (if applicable) must have been performed within 6 weeks that the patient had involvement of the neck region by palpation / physical examination at first diagnosis (pre-CHOP-R)
