Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Safety, Efficacy, Others
To evaluate the efficacy of venetoclax (Venclexa® or Venclyxto®) in combination with obinutuzumab (Gazyva® or Gazyvaro®) (VEN + G) compared with fludarabine, cyclophosphamide, and rituximab (FCR)/ bendamustine and rituximab (BR) on the basis of minimal residual disease (MRD) response rate
Secondary objectives 3
- To evaluate the efficacy of VEN + G compared with FCR/BR on the basis of progression-free survival, MRD response rate in peripheral blood (PB) and bone marrow (BM), overall response rate, duration of objective response, best response achieved, event-free survival, overall survival, tumor lysis syndrome risk reduction rate and reduction in mandatory hospitalizations
- To evaluate safety of VEN + G compared with FCR/BR on the basis of nature, frequency, and severity of adverse events, changes in vital signs, physical findings, clinical laboratory test results, premature withdrawals
- To compare disease and treatment-related symptoms and to evaluate changes in physical functioning, role functioning, and global health status/quality of life following treatment with the combination of VEN + G compared with FCR/BR in patients with previously untreated CLL without del(17p) or TP53 mutation

| 1 | PHASE III STUDY TO COMPARE VENETOCLAX/OBINUTUZIMAB VS FLUDARABINE CYCLOPHOSPHAMIDE + FCR/BENDAMUSTIN A Study to Compare the Efficacy and Safety of a Combined Regimen of Venetoclax and Obinutuzumab Versus Fludarabine, Cyclophosphamide, and Rituximab (FCR)/ Bendamustine and Rituximab (BR) in FIT Patients With Previously Untreated Chronic Lymphocytic Leukemia (CLL) without DEL (17P) or TP53 mutation
|
Randomised Controlled | None | ARM A: Patients randomized to Arm A (VEN G) will receive 12 cycles of treatment, each with a precise duration of 28 days. During the first cycle, obinutuzumab will be administered intravenously on Days 1 (and 2), 8, and 15 as well as on Day 1 of Cycles 26. Continuous daily administration, with a 5-week ramp-up period, of venetoclax starts on Cycle 1, Day 22. Venetoclax will be administered until the end of Cycle 12. ARM B: Patients randomized to Arm B (FCR/BR 50:50) will receive 6 cycles of FCR consisting of a single cycle of a single infusion of rituximab on Day 1 and fludarabine and cyclophosphamide infusions on Days 13 of each 28-day cycle or bendamustine as infusions on Days 1 and 2 and a single cycle of rituximab on Day 1 of each 28-day cycle. |
