Study Details
Study Description
Brief Summary
Phase II study testing chemo-free induction therapy with Ibrutinib + Obinutuzumab nine months /
Study Part 1:
All patients will receive 8 courses of GA101 + ibrutinib 420mg PO every 28 days
Study Part 2:
After evaluation at D1 of month 9:
If patients are in CR with BM MRD < 10-4, they will continue ibrutinib alone at a dose of 420mg daily If patients have BM MRD >10-4 whatever IWCLL 2008 responses or PR they will receive four courses of GA101 + FC at 28-day intervals + Ibrutinib PO until final evaluation of M16

| Phase 2 |
Detailed Description
Phase II study testing chemo-free induction therapy with Ibrutinib + Obinutuzumab during nine months followed by a MRD-driven strategy. Assessment of response as well as bone marrow MRD evaluation will be performed at Day 1 month 9:
-
Patients reaching CR with marrow MRD below 10-4 threshold will continue ibrutinib during 6 additional months.
-
Patients in PR or bone marrow MRD > 10-4 will receive Ibrutinib during 6 additional months and 4 courses of FC+ GA101. At Day 1 Month 16, patients in CR but with MRD> 10-4 will continue Ibrutinib until progressive disease.
-
Patients in stable or progressive disease will be excluded out of the trial.
Final evaluation of response (with BM MRD) will be performed at Day 1 Month 16.
