Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Main objective of the trial ist to evaluate the efficacy of two regimens of immunochemotherapy, i.e. Fludarabine, Cyclophosphamide plus GA101 (FCG) and Bendamustine plus GA101 (BG), in patients with relapsed or refractory CLL.;Secondary Objective: - To evaluate the safety of the regime of immunochemotherapies, i.e. Bendamustine plus GA101 (BG) in patients with relapsed or refractory CLL followed by maintenance therapy with GA101 for responding patients. - To investigate the feasibility of a maintenance therapy with GA101 following either a regimen of BG for responding patients. - To evaluate descriptively safety and efficacy of the BG regimen in patients with relapsed or refractory CLL.;Primary end point(s): Best overall response rate (ORR) defined as best response assessed until and including response assessment at follow up 2 (6 months after final restaging/ induction), defined by the proportion of patients having achieved a CR/ CRi, clinical CR/ CRi or nPR/ PR as best response based on the respective population (= number of patients with best response CR/ CRi, clinical CR/ CRi or nPR/ PR divided by the number of the respective population);Timepoint(s) of evaluation of this end point: The analysis of the primary endpoint will be performed 60 months after the last patient was randomized. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • MRD levels during treatment and maintenance • Progression free survival (PFS) • Event-free survival (EFS) • Overall survival (OS) • Overall response to maintenance treatment • Duration of response in patients with CR/ CRi, clinical CR / clinical CRi or nPR/ PR • Time to next anti-leukemia treatment • Overall response rate in biological defined risk groups • Complete response rate • Safety parameters during induction and maintenance phase [type, frequency, and severity of adverse events (AEs), AESI (AEs of special interest) and relationship of AEs to study treatment] • Evaluation of relationship between various baseline markers and clinical outcome parameters;Timepoint(s) of evaluation of this end point: The analysis of the primary endpoint will be performed 60 months after the last patient was randomized. | — |
