Study information

Primary study design	Interventional
Study design	Multicentre randomised interventional treatment trial
Secondary study design	Randomised controlled trial
Study type	Participant information sheet
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 acronym	IELSG19/MALT Trial
Study objectives	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(s)	South East Multi-Centre Research Ethics Committee, 30/04/2003 (ref: 03/1/031). Amendment approved on the 30/10/2006.
Health condition(s) or problem(s) studied	Topic: National Cancer Research Network; Subtopic: Lymphoma; Disease: Lymphoma (non-Hodgkin's)
Intervention	ARM A: Chlorambucil 6 mg/m2 daily orally (p.o.) for 42 consecutive days (weeks 1 - 6) ARM B: Chlorambucil 6 mg/m2 daily p.o. for 42 consecutive days (weeks 1 - 6) and rituximab 375 mg/m2 intravenous (iv) on days 1, 8, 15, 22 during the first month (4 weekly doses) ARM C: Rituximab 375 mg/m2 iv on days 1, 8, 15, 22 during the first month (4 weekly doses) Study entry: single randomisation only
Intervention type	Drug
Phase	Phase III
Drug / device / biological / vaccine name(s)	Chlorambucil, rituximab
Primary outcome measure(s)	Event-free-survival (EFS) (failure or death from any cause) for all patients

No evidence of symptomatic central nervous system (CNS) disease 16. No impairment of bone marrow function (white blood cells [WBC] greater than 3.0 x 10^9/L, absolute neutrophil count [ANC] greater than 1.5 x 10^9/L, platelets [PLT] greater than 100 x 10^9/L), unless due to lymphoma involvement 17. No major impairment of renal function (serum creatinine less than 1.5 x upper normal) or liver function (aspartate aminotransferase [ASAT]/alanine aminotransferase [ALAT] less than 2.5 upper normal, total bilirubin less than 2.5 x upper normal), unless due to lymphoma involvement 18.
