Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 82 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Preemptive Therapy With Venetoclax for High Risk Chronic Lymphoid Leukemia Stage A Patients, a Phase II Trial of the FILO
Actual Study Start Date : May 22, 2019
Actual Primary Completion Date : January 22, 2022
Estimated Study Completion Date : February 1, 2028

Arm Intervention/treatment
Experimental: ARM A VENETOCLAX
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).

Primary Outcome Measures :
  1. Complete response rate [ Time Frame: 12 months ]
    according to International Workshop Chronic Lymphoid Leukemia 2008 guidelines and with Minimal Residual Disease inferior to 0.01 percent (as determined by 8-color technique) in bone marrow at month 12.
