Single-arm, phase II clinical trial of patients with Extranodal Marginal Zone Lymphoma (EMZL). It is planned to recruit 130 patients.
Additional patients with Splenic Marginal Zone Lymphoma (SMZL), up to 30, and Nodal Marginal Zone Lymphoma (NMZL), up to 15, will be included in the trial in order to preliminary explore the clinical activity and safety of the combination treatment proposed.
The study primary endpoints will be analysed on the EMZL population. Outcome of patients with SMZL and NMZL will be analysed and reported separately

Marginal zone lymphomas (MZL) represent a group of indolent B-cell lymphomas that arises from marginal zone B-cells in extranodal tissues, such as spleen and mucosa associated lymphoid tissues, and more rarely also in nodal tissues. MZL comprises 5 to 17% of all non-Hodgkin lymphomas (NHL) in adults. The 2016 World Health Organization (WHO) recognized three separate subtypes of MZL according to their primary localization, namely the:
- extranodal MZL (EMZL) of mucosa-associated lymphoid tissue (MALT), also known as MALT lymphoma
- splenic MZL (SMZL)
- nodal MZL (NMZL). These three subtypes are distinct disease entities that are classified together because they all seem to originate from post germinal centre marginal zone B-cells.
MALIBU trial is a prospective multicenter trial combining rituximab and ibrutinib in front-line for patients with MZL, including EMZL, SMZL and NMZL Aim of the study is to assess the safety and efficacy of the combination of rituximab and ibrutinib in EMZL patients and to explore its activity in SMZL and NMZL as exploratory subset.

EMZL (MALT Lymphoma) patients with MALT- IPI score 1-2 in need of systemic therapy.
Either de novo or relapsed following local therapy (including surgery, radiotherapy and antibiotics for H. pylori-positive gastric lymphoma) arisen at any extranodal site with MALT-international prognostic index (IPI) score 1-2 at the time of study entry.
1.1.The following patients with gastric MALT Lymphoma can be entered:
- H. pylori-negative cases, either de novo (non pretreated) or at relapse following local therapy (i.e., surgery, radiotherapy or antibiotics).
-
H. pylori-positive cases at diagnosis, who either first line antibiotics or further local treatment (surgery or radiotherapy), including patients with:

- clinical (endoscopic) and histological relapse (without H. pylori re-infection), after a remission patients;
- persistent (stable) lymphoma at ≥ 1 year post H. pylori eradication. 1.2. Similar consideration may be applied to patients with ocular adnexal lymphoma treated with antibiotics.
-
SMZL patients in need of therapy. Either de novo or relapsed following local therapy [including surgery and antiviral therapy for Hepatitis C virus (HCV)]. Patient must have a symptomatic disease requiring treatment and be not eligible for splenectomy or not willing to undergo splenectomy.
