Summary

Primary objectives:

  • Randomization R1, all patients eligible: To examine, whether the cumulative incidence of relapses with involvement of the CNS (CNS relapse, pCICR) can be decreased by a modified induction therapy including dexamethasone (experimental arm) instead of prednisone (standard arm)
  • Randomization R2, only patients with high risk LBL eligible: to examine, whether the probability of event-free survival (pEFS) in these patients can be improved by receiving an intensified treatment arm versus a standard treatment arm (as used in the EURO-LB 02)

Description

The trial LBL 2018 is a collaborative prospective, multi-national, multi-center, randomized clinical trial for the treatment of children and adolescents with newly diagnosed lymphoblastic lymphoma.

The LBL 2018 trial will be open for the qualified centers of following participating study Groups (core study cohort): AIEOP (Italy), BFM (Austria, Czech Republic, Germany, Switzerland), BSPHO (Belgium), CoALL (Germany), DCOG (The Netherlands), NOPHO (Denmark, Finland, Norway, Sweden), PPLSG (Poland), SEHOP (Spain) and SFCE (France). HKPHOSG (Hong Kong), HPOG (Hungary), ISPHO (Israel), NSPHO (Moscow), PHOAI (Ireland), SHOP (Portugal) and SPS (Slovak Republic) start patient recruitment into the extended study cohort (without randomization). Over the trial period study groups may switch from the extended study cohort to the core study cohort.

Primary objectives:

  • Randomization R1, all patients eligible: To examine, whether the cumulative incidence of relapses with involvement of the CNS (CNS relapse, pCICR) can be decreased by a modified induction therapy including dexamethasone (experimental arm) instead of prednisone (standard arm)
  • Randomization R2, only patients with high risk LBL eligible: to examine, whether the probability of event-free survival (pEFS) in these patients can be improved by receiving an intensified treatment arm versus a standard treatment arm (as used in the EURO-LB 02)

Patients are stratified into 3 different risk groups according to CNS status, immunophenotype, genetic markers and stage of disease at diagnosis: high risk group (HR), standard risk group I/II (SR I/II) and standard risk group (SR).

Patients in the risk groups SR I/II and SR are randomized (R1) in two arms after a cytoreductive prephase with prednisone. Patients in standard arm receive the standard induction phase with prednisone. Patients in the experimental arm receive an induction phase with dexamethasone instead of prednisone.

In SR group, induction phase is followed by the consolidation phase, the non-HR extra-compartment phase with HD-MTX (high-dose methotrexate), the reintensification phase and the maintenance therapy for the total therapy duration of 24 months. In SR I/II group, patients receive no reintensification phase. The Induction phase is followed by the consolidation phase, the non-HR extra-compartment phase and the maintenance therapy for the total therapy duration of 24 months.

Patients in the HR group are eligible for randomization (R1) as outlined above. In addition high risk patients are eligible for second randomization (R2) at the end of induction phase. In the standard arm, HR-patients receive the consolidation phase and the non-HR extra-compartment phase. In the experimental arm, HR-patients receive a consolidation phase including two additional doses of PEG asparaginase and the HR-intensified extra-compartment phase consisting of two high risk courses alternating with two HD-MTX courses. Either phase is followed by the reintensification phase and the maintenance therapy for the total therapy duration of 24 months.

Patients with involvement of the CNS (CNS positive) are stratified to the high risk group (HR) and are eligible for both randomizations (R1 and R2). Additionally, patients with CNS involvement (CNS positive) receive intensified intrathecal therapy. Intrathecal therapy consists of TIT (triple intrathecal therapy) after diagnosis of CNS involvement. TIT is administered twice weekly until clearance of blasts in the cerebrospinal fluid is achieved. Further intrathecal therapy is provided at the same points of time as for patients without CNS involvement, but TIT instead of MTX IT. In addition, patients receive four additional doses of TIT during maintenance. Cranial irradiation is omitted for patients with CNS involvement.

Eligibility

Yes No Not Sure

Inclusion Criteria

newly diagnosed lymphoblastic lymphoma
age <18 years
patient enrolled in a participating center
written informed consent of patient (>14 years of age or according to local law and regulation) and parents to trial participation and transfer and processing of data
willingness of patients and the investigator/pathologist to provide adequate slides/blocks for reference (molecular) pathology and international pathology panel and/or fresh or fresh frozen samples for genetic risk group stratification if these samples are available after standard diagnostic procedures

Exclusion Criteria

lymphoblastic lymphoma as secondary malignancy
non-lymphoma related relevant medical, psychiatric or social conditions incompatible with trial treatment, including among others
prior organ transplant
severe immunodeficiency
demyelinating Charcot-Marie Tooth syndrome
serious acute or chronic infections, such as HIV, VZV and tuberculosis
urinary tract infection, cystitis, urinary outflow obstruction, severe renal impairment (creatinine clearance less than 20 ml/min)
severe hepatic impairment (bilirubin >3 times ULN, transaminases >10 times ULN)
myocardial insufficiency, severe arrhythmias
ulcers of the oral cavity and known active gastrointestinal ulcer disease
known hypersensitivity to any IMP and to any excipient (listed in section 6.1 of the respective SmPC)
steroid pre-treatment with 1 mg/kg/d for more than two weeks during the last month before diagnosis
vaccination with live vaccines within 2 weeks before start of protocol treatment
treatment started according to another protocol or pre-treatment with cytostatic drugs
participation in another clinical trial that interferes with the protocol, except NHL-BFM Registry 2012 and trials with different endpoints, involving aspects of supportive treatment, which can run parallel to LBL 2018 without influencing the outcome of this trial (e.g. trials on antiemetics, antibiotics, strategies for psychosocial support)
evidence of pregnancy or lactation period
sexually active adolescents not willing to use highly effective contraceptive method (pearl index < 1) until 12 months after end of cytostatic therapy
