  • serum monoclonal protein level ≥ 1 g/dl (≥ 10 g/l) or
  • urine M-protein level ≥ 200 mg/24hours or
  • serum FLC assay: Involved FLC level ≥ 10 mg/dl (≥ 100 mg/l) provided serum FLC ratio is abnormal
• ECOG performance status 0, 1, or 2
• Age ≥ 18 years
• All previous cancer therapy (except corticosteroid therapy), including radiation, cytostatic therapy and surgery, must have been discontinued at least 4 weeks prior to treatment in this study.
• No prior treatment with a bendamustine-containing regimen allowed
• Prior treatment with lenalidomide is allowed if the treatment is completed > 12 month prior to study entry and the patient responded to prior lenalidomide treatment

• Adequate hematological values:

  • absolute neutrophil count ≥ 1.5 x 109/L
  • platelets ≥ 100 x 109/L
  • hemoglobin > 80 g/L, unless considered to be caused by the underlying hematologic malignancy, based on the investigator's clinical judgement

• Adequate hepatic function:

  • total bilirubin < 1.2 mg/dL
  • AST (SGOT) ≤ 2.5 x ULN

• Adequate renal function:

  o calculated creatinine clearance > 50 ml/min, according to the formula of Cockcroft-Gault

• Disease free of prior malignancies for > 5 years unless the patient

  • has been treated with a curative intent and is considered to be in complete remission for ≥2 years prior to study enrolment

  • or has a curatively-treated

    • basal cell/ squamous cell carcinoma of the skin,
    • carcinoma "in situ"of the cervix,
    • ductal breast carcinoma in situ with complete surgical resection (i.e. negative margins),
    • medullary or papillary thyroid tumor

Exclusion Criteria:

• Pregnant or breast feeding females
• Any prior use of bendamustine
• Patients who are unable or unwillingly to undergo antithrombotic therapy
• Any serious underlying medical condition (at the judgment of the investigator) which impairs the ability of the patient to participate in the trial (e.g. active autoimmune disease, uncontrolled diabetes, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, psychiatric disorder)
• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she would participate in the study or any condition significantly confounding the ability to interpret data from the study, based on the local investigator's judgement
• Severe cardiovascular disease, including myocardial infarction within 6 months before study entry, New York Heart Association Class III or IV heart failure, uncontrolled angina or severe uncontrolled ventricular arrhythmias (≥ Lown 3)
• Use of any other experimental drug or therapy/ treatment in a clinical trial within 30 days prior to trial entry
• Known hypersensitivity to study drug(s) or hypersensitivity to any other component of the study drugs
• Any concurrent antineoplastic therapy with chemotherapeutic agents or biologic agents or radiation therapy
• Any major surgical procedure within 30 days prior to study therapy
• Known chronic hepatitis B or C, known HIV infection
• Jaundice or any other severe damage of the liver parenchyma
• Any contraindication for the treatment with bendamustine, lenalidomide, dexamethasone and / or pegfilgrastim in accordance with the appropriate SmPCs
• Any other concomitant drugs contraindicated for use with the study drugs according to the national health authorities
