CLLM1-PROTOCOL OF THE GERMAN CLL-STUDY GROUP (GCLLSG) Screening supported by a central review allows a precise selection of the population for maintenance therapy within the CLLM1 trial of the German CLL Study Group Anne Westermann, DCLLSG, Uniklinik Köln, 22.02.2014 DKK 1 Approach: individualized CLL therapy Personalized treatment plan tailored to patients needs and diagnosis. Staging Lymphocyte doubling time Response to treatment Molecular cytogenetics 17p-Deletion, TP53 Mutation, …. Physical fitness Go go slow go No go MRD Intensify therapy if MRD+ Maintenance therapy? Patient-specific treatment comorbidities, renal function… + CLL-specific treatment Molecular cytogenetics, Lymphocyte doubling time, Serum thymindine kinase… OUTCOME CLL8 TRIAL PFS according to TP 53 PFS according to 17p 3 OUTCOME CLL8 TRIAL PFS according to MRD PFS according to IGHV 4 RATIONALE OF CLLM1 Patients with high risk of early PD after Firstline have short survival no standard treatment options few patients are eligible for stem cell transplantion Why Lenalidomide? effective and approved for treatment of relapsed and refractory multiple myeloma ensures recovery of T-cell defects direct CD8+ T-cell killing of B-CLL cells 5 DEFINITION OF HIGH RISK High MRD level ≥10-2 or Median MRD level ≥ 10-4 -<10-2 combined with at least one of the following del(17p) TP53 mutation unmutated IGHVstatus 6 CLLM1-STUDY DESIGN Physically fit and previously untreated patients with treatment requiring disease Firstline investigator‘s choice (FCR, BR, FR (FC) 700 High Risk 2: 1 Rando screening patients High Risk 200 randomized patients L‐maintenance placebo Treatment up to PD CLLM1 TRIAL Risk assessments performed within 8 to 13 months Up to 6 months prior to Firstline therapy Central lab results of TP53, 17p, IGHV • Complete or incomplete local results of TP53, 17p, IGHV 4‐6 months firstline therapy Firstline‐ Therapy 2‐5 months after end of last cycle Mandatory MRD‐ Analysis in Kiel Risk Assessment: Patients with low risk Patients with high risk MEDICAL REVIEW Patient data are checked by GCLLSG Physicians Fit patients: CIRS<6 Response to Firstline Renal function: Crea-clearance > 60ml/min Exclusion of active Infection/Hematoxicity 9 REASONS FOR PATIENT‘S WITHDRAWAL 10 PATIENTS DROP OUT/ LOW RISK 442 32 Registered patients Drop outs Firstline Therapy 69 Drop outs 162 Pts screened after firstline 123 Pts with low risk 34 Pts randomized 11 REASONS FOR DROP OUT 1 patient’s Decision 2 other disease 3 no adequate firstline therapy 4 treatment related reasons 12 REASONS FOR PATIENT‘S WITHDRAWAL SURVEY DECEMBER 2013 1 tired of treatment 2 afraid of lenalidomide side effects 3 concerned of frequent visits 13 CONCLUSION Maintenance therapy after a careful selection of a subgroup with high risk is feasible if Patients and doctors are convinced of the study drug and the benefits of maintenance therapy 14 Thank you!
