Exclusion Criteria:

• Binet Stage A patients with progressive disease according to International Workshop Chronic Lymphoid Leukemia 2008 criteria

Intervention

Drug:
• Venetoclax
Venetoclax is administered according to the usual schedule an escalating dose from 20 milligram per day the first week, then 50 milligram per day the second week, 100 milligram per day the third week, 200 milligram per day the fourth week and then 400 milligram per day. For patient achieving a Compete Response with Minimal Residual Disease inferior to 0,01 percent in bone marrow at month 12, treatment will be stopped at month18 (18 months for total duration of treatment ). For responding patients at month12 (Complete Response or Partial Response) with bone marrow Minimal Residual Disease inferior to 0.01 percent, treatment will be continued until month 24 (24 months for total duration of treatment).
