Yt90 Zevalin and Combination Chemotherapy (Z-CHOP)in Treating Patients With Stage II, Stage III, or Stage IV Diffuse Large B-cell Lymphoma

Phase 2

Terminated

• Conditions: Diffuse Large B-cell Lymphoma

• Registration Number: NCT00386321
• Lead Sponsor: Chulalongkorn University

Brief Summary

The purpose of this study is to determine whether the treatment of Yt90 Zevalin in combination with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone)are effective as first line treatment in patients with bulky stage II or stage III or IV diffuse large B-cell lymphoma

Detailed Description

Radioimmunotherapy represents a significant advance over unlabeled immunotherapy for the treatment of patients with B-cell non-Hodgkin's lymphoma. The radiobiological effects associated with Yt90-labelled ibritumomab tiuxetan (Zevalin) include the induction of apoptosis and cell-cycle redistribution.

The response rate tend to be higher in patients who have been treated with fewer prior therapies and Yt90-labelled ibritumomab tiuxetan may be suitable for use early in the course of therapy.

Yt90-labelled ibritumomab tiuxetan has less non hematologic toxicity than chemotherapy, with only minimal alopecia, mucositis, nausea, or vomiting, and a lower incidence of infections.

Yt90-labelled ibritumomab tiuxetan regimen is routinely and safely given in an outpatient setting and is completed in 7-9 days and is thus more convenient to be used.
