Spots Global Cancer Trial Database for Phase II Study of Chlorambucil and Subcutaneous Rituximab in Patients With Extranodal MALT Lymphoma

Study Description

Brief Summary: Single arm phase II study of Chlorambucil in combination with subcutaneous Rituximab followed by maintenance therapy with subcutaneous Rituximab in patients with histologically proven diagnosis of CD20-positive marginal zone B-cell lymphoma of MALT type arisen at any extranodal site, either de novo, or relapsed following local therapy (including surgery, radiotherapy and antibiotics for H. pylori-positive gastric lymphoma).

Detailed Description: The study consists in three parts. In Part A (induction phase I) patients will be treated with Chlorambucil 6 mg/m2 daily p.o for 42 consecutive days (weeks 1-6) in combination with intravenous Rituximab 375mg/m2 on day 1 week 1 followed by subcutaneous Rituximab 1400mg on days 8, 15 and 22 (day 1 of weeks 2, 3 and 4). After restaging (CT scan to be performed during weeks 7-8, i.e. between d42 and d55), responding patients (CR, CRu, PR) and those with stable disease will be treated in part B (induction phase II). In part B, starting from d56, (month 3) patients will receive Chlorambucil 6 mg/m2 daily p.o for 14 consecutive days (d1-14) every 28 days for 4 cycles in combination with subcutaneous Rituximab 1400mg on day 1 of each 28-day cycle. After restaging (CT scan to be performed at the end of month 6) responding patients and those with stable disease will be treated in part C. In Part C (maintenance phase) patients will be treated with subcutaneous Rituximab 1400mg every two months for 2 years (in total 12 injections). During maintenance phase, CT scans will be performed every 12 months and patients responding or with stable disease will stay on treatment for a total of two years as above reported.
