4. Measurable lesion on MRI with gadolinium enhancement.

5. Adequate hematological, renal and hepatic function (Laboratory Parameters realized within 14 days before inclusion):

   1. Absolute neutrophil count (ANC) >1000/mm3
   2. Platelets > 100,000/mm3 independent of transfusion support
   3. Alanine aminotransferase and aspartate aminotransferase ≤ 3 x Upper Limit of Normal (ULN)
   4. Total bilirubin ≤ 1.5 x ULN unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin

Men must agree to not to father a child or donate sperm during treatment by Lenalidomide or Ibrutinib and up to 3 months after the last dose of study drug.
10. Women of childbearing potential (WCBP)* must have a negative serum (beta-human chorionic gonadotropin [B-hCG]) or urine pregnancy test at inclusion.
11. Signed informed consent, which could be signed by a person on confidence in case the neurologic status of the patient does not allow him to understand and/or to sign.
