Design Prospective, multicenter, open-label phase-II trial
Primary Objective To evaluate the efficacy of Bendamustine plus GA101 (BG) in patients with relapsed CLL
Primary Endpoint Overall response rate (ORR)
Secondary Endpoints - 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
- Complete response rate
- Komplette Ansprechrate (Complete response rate)
- Safety parameters during induction and maintenance phase (AEs, AESI)
- Evaluation of relationship between various baseline
markers and clinical outcome parameters
- Evaluation of patients randomized into the prematurely closed FCG study arm with regard to efficacy and safety parameters
Study Population - B-CLL in need of treatment according to the iwCLL guidelinese IWCLL guidelines
- Relapsed disease
