Lenalidomide Plus Rituximab (R) in Non Follicular NHL

This is an interventional treatment trial for Indolent Non Hodgkin Lymphoma Read More

Inclusion Criteria:

• Histological confirmed diagnosis of B-Cell non follicular NHL according to REAL/WHO Classification: small lymphocytic lymphoma, lymphoplasmacytic lymphoma/Waldenstrom macroglobulinemia, nodal marginal zone lymphoma, splenic marginal zone lymphoma, extranodal non-gastric marginal zone lymphoma
• Availability of tissue biopsy mandatory when suspected pathological sites (nodal or extranodal) are easily accessible and in presence of extranodal non-gastric marginal or nodal marginal zone lymphoma diagnosis. In the other cases bone marrow biopsy, when representative, may be considered sufficient for defining lymphoma histotype
• Disease relapsing after >=2, but less than 4 prior lines of (immuno)chemotherapy. At least one of previous treatment had to include rituximab
• Presence of at least one of the following criteria for the definition of active disease: systemic symptoms, bulky disease, progressive marrow failure and/or splenomegaly and/or lymph adenopathy
• Age 18-75
• Life expectancy > 6 months
• Eastern Cooperative Oncology Group (ECOG) <=2
• Left ventricular ejection fraction (LVEF) >=45%
• Creatinine clearance >= 50 mL/min calculated by Cockcroft-Gault estimation; patients with creatinine clearance >= 30 and < 50 mL/min, at physician discretion could enter the study starting at lenalidomide dose level -2 (10 mg)
• Total bilirubin up to 2 x upper limit of normal(ULN). Total bilirubin values higher than 2 x ULN are admitted if related to localization of the disease
• Alkaline phosphatase up to 2 x ULN and transaminases up to 3 x ULN
• Female and male patients must agree to participate in pregnancy prevention program signing informed Consent (paragraph 5.4.)
• Written informed Consent

Exclusion Criteria:

• Previously untreated patients
• Patients with diagnosis of typical Chronic Lymphocytic Leukemia (CLL)
• Women and men not agreeing to take adequate contraceptive precautions during and for at least 4 weeks after cessation of therapy
• Pregnant or lactating women
• History of other malignancies within 3 years prior to study entry except for adequately treated carcinoma in situ of the cervix or basal or squamous cell skin cancer, low grade, early stage localized prostate cancer treated surgically with curative intent, good prognosis ductal carcinoma in situ (DCIS) of the breast treated with lumpectomy alone with curative intent
• Active bacterial, viral or fungal infection requiring systemic therapy
• Concurrent co-morbid medical condition which might exclude administration of therapy
• Cardiac insufficiency (NYHA grade III/IV)
• Myocardial infarction within 6 months of entry on the study
• Severe chronic obstructive pulmonary disease with hypoxemia
• Severe diabetes mellitus difficult to control with adequate insulin therapy
• Hypertension that is difficult to control
• Creatinine clearance < 30 mL/min calculated by Cockcroft-Gault estimation
• Absolute neutrophil count (ANC) <= 1 x 109/L, unless due to lymphoma involvement and not responding to 5 days of Granulocyte colony-stimulating factor (G-CFS) treatment
• Platelets count <=75.000/mm3, unless due to lymphoma involvement
• HIV and Hepatitis B virus (HBV) positivity
• Hepatitis C virus (HCV) positivity in presence of high level of virus replication and Aspartate aminotransferase (AST)/Alanine aminotransferase (ALT) > x 2.5 ULN
• Central nervous system (CNS) involvement by lymphoma
• Known hypersensitivity or anaphylactic reactions to murine antibodies or proteins
• Any other co-existing medical or psychological condition that would preclude participation in the study or compromise ability to give informed consent
