Study information

Scientific title

Multi-centre randomised trial of chlorambucil versus chlorambucil plus rituximab versus rituximab alone in extranodal marginal zone b-cell lymphoma of mucosa associated lymphoid tissue (malt lymphoma)



Study hypothesis

The aim of the study is to assess the therapeutic activity and the safety of the combination of chlorambucil and rituximab in mucosa associated lymphoid tissue (MALT) lymphomas and to determine whether the addition of ritxuiamb to chlorambucil will improve the outcome of MALT lymphoma in comparison to treatment with chlorambucil alone. Also to compare the anti-tumor activity and safety of rituximab alone versus chlorambucil alone.

Ethics approval

South East Multi-Centre Research Ethics Committee approved on the 30th April 2003 (ref: 03/1/031). Amendment approved on the 30th October 2006.
