• Written informed consent

Exclusion Criteria:

• Grade 3B follicular lymphoma
• Presence or history of CNS disease (either CNS lymphoma or leptomeningeal lymphoma).
• Known hypersensitivity to any of the study drugs
• Known sensitivity to murine products
• Regular use of corticosteroids during the last 4 weeks, unless administered at a dose equivalent to < 20 mg/day prednisone.
• Concomitant use of strong CYP3A4 inhibitors and / or oral anticoagulants (warfarin and/or phenprocoumon)

• Prior or concomitant malignancies except:

  • non-melanoma skin cancer or adequately treated in carcinoma in situ of the cervix
  • Other malignant diseases not specified above which have been curatively treated by surgery alone and from which subject is disease-free for ≥5 years without further treatment

• Serious disease interfering with a regular therapy according to the study protocol:

  • Clinically significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of Screening, or any Class 3 (moderate) or Class 4 (severe) cardiac disease as defined by the New York Heart Association Functional Classification
  • pulmonary (e.g. chronic lung disease with hypoxemia)
  • endocrine (e.g. severe, not sufficiently controlled diabetes mellitus)
  • renal insufficiency (unless caused by the lymphoma): creatinine > 2x normal value and/or creatinine clearance < 50 ml/min)
  • impairment of liver function (unless caused by the lymphoma): transaminases > 3x normal or bilirubin > 2,0 mg/dl (unless caused by known Morbus Meulengracht [Gilbert-Meulengracht-Syndrome])
• Positive test results for chronic HBV infection (defined as positive HBsAg serology) Patients with occult or prior HBV infection (defined as negative HBsAg and positive total HBcAb) may be included if HBV DNA is undetectable, provided that they are willing to undergo monthly DNA testing. Patients who have protective titers of hepatitis B surface antibody (HBsAb) after vaccination or prior but cured hepatitis B are eligible.
• Positive test results for hepatitis C (hepatitis C virus [HCV] antibody serology testing). Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA.
• Known history of HIV seropositive status.

• Vaccination with a live vaccine within 28 days prior to registration
• Recent major surgery (within 4 weeks prior to the start of Cycle 1)
• History of stroke or intracranial hemorrhage within 6 months prior to registration
• Serious underlying medical conditions, which could impair the ability of the patient to undergo the treatment offered in the study (e.g. ongoing infection, gastric ulcers, active autoimmune disease)
• Treatment within a clinical trial within 30 days prior to trial entry.
• Prior organ, bone marrow or peripheral blood stem cell transplantation
• Known or persistent abuse of medication, drugs or alcohol
• Any other co-existing medical or psychological condition that will preclude participation in the study or compromise ability to give informed consent.
