Sequential Regimen of Bendamustine-Debulking Followed by CAL-101 and GA101-Induction and -Maintenance in CLL (CLL2-BCG)

CompletedPhase 2

Sponsor: German CLL Study Group

Conditions: Chronic Lymphocytic Leucemia

Interventions: Bendamustine, GA101, CAL-101

Countries: Germany

The CLL2-BCG-trial is a prospective, open-label, multicenter phase-II-trial to evaluate the efficacy and safety of a sequential regimen of a debulking with bendamustine followed by an induction with GA101 (obinutuzumab) and CAL-101 (idelalisib) followed by CAL-101 and GA101-maintenance in CLL patients

Eligibility criteria

Inclusion Criteria:

* adequate renal function: a creatinine clearance ≥30ml/min calculated according to the modified formula of Cockcroft and Gault or directly measured with 24 hr. urine collection
* adequate liver function: total bilirubin ≤1,5x, aspartate aminotransferase (AST) / alanin aminotransferase (ALT) ≤2.5x the institutional upper limit of normal (ULN) value, unless directly attributable to the patient's CLL or to Gilbert's Syndrome
* negative serological testing for hepatitis B, negative testing for hepatitis-C RNA and negative HIV test within 6 weeks prior to registration

* any comorbidity or organ system impairment rated with a cumulative illness rating scale (CIRS) score of 4, excluding the eyes/ears/nose/throat/larynx organ system or any other life-threatening illness, medical condition or organ system dysfunction that - in the investigator´s opinion - could compromise the patients safety or interfere with the absorption or metabolism of the study drugs (e.g, inability to swallow tablets or impaired resorption in the gastrointestinal tract)
* ongoing inflammatory bowel disease
* ongoing drug induced pneumonitis
