LBL 2018, International Cooperative Therapeutic Protocol for Children and Adolescents with Lymphoblastic Lymphoma
Summary description of the study
The LBL 2018 study is an international therapeutic optimization study conducted by the NHL-BFM study group in cooperation with other countries in Europe and beyond. The concept of the LBL 2018 study was developed based on the results of previous studies and the latest international knowledge available. This study also includes a part aimed at addressing new scientific questions. The current standard treatment for LLB, consisting of a combination of various chemotherapeutic agents, has not fundamentally changed in the last two decades. It is accompanied by significantly high rates of acute side effects, but also long-term consequences that need to be taken into account. Furthermore, the more unfavorable survival rates of patients with advanced disease and the disastrous prognosis that still concerns the majority of patients in case of relapse (reappearance of the disease) remain problematic. Therefore, the main objectives of the LBL 2018 therapeutic optimization study are to improve cure rates and prevent the occurrence of relapses, particularly at the level of the brain and spinal cord (central nervous system, CNS).

Intervention under investigation
A fundamental principle of therapeutic optimization studies is to controlledly examine the effects of new or modified therapeutic components on cure chances and side effects compared to the established standard treatment from previous studies. To assess whether the modified treatment group provides a benefit over the standard treatment, randomization is performed, namely a random allocation into the different treatment groups. The LBL 2018 study includes two randomizations: R1: all patients in the study will participate in this randomization. There is scientific knowledge suggesting that the use of the dexamethasone cortisone preparation instead of prednisone (another cortisone preparation) at the beginning of treatment may reduce the likelihood of relapse of LLB with CNS involvement. Conversely, however, a higher risk of side effects has been observed with the use of dexamethasone depending on the dose and duration of treatment. Within the framework of the LBL 2018 study, a randomized comparison will be conducted to determine whether the use of dexamethasone for a short duration (to minimize the risk of side effects as much as possible) reduces the occurrence of relapses at the CNS level compared to standard treatment with prednisone. R2: for patients in the high-risk group, it will be examined in comparison to standard treatment whether a second, more intensive part of the treatment (according to protocol Ia) improves cure rates. The new component of the intensive treatment for the experimental group includes the administration of two cycles of high-dose chemotherapeutic agents that are already established in the treatment of children and adolescents with a related condition, high-risk acute lymphoblastic leukemia (ALL). At the same time, an increase in side effects is to be expected with the intensification of treatment.

Primary and secondary end points
Main Objective: The primary objective of the first randomized question (R1) open for all LBL patients (pts) of the core study cohort, is to evaluate whether the cumulative incidence of relapses in the central nervous system can be decreased by substituting prednisone (60 mg/m?/d for 21 days plus a 9 day tapering) (standard arm, SA) by dexamethasone (10 mg/m?/d for 14 days without tapering) (experimental arm, EA) in induction therapy. The primary objective of the second randomized question (R2) open for high-risk pts of the core study cohort, is to test whether the probability of pEFS can be improved by an intensified treatment arm (EA) compared to the standard treatment arm (SA). In the EA pts receive 2 additional doses of PEG asparaginase during protocol Ib* and an intensified protocol M consisting of one course for high-risk (HR) ALL (HR-1?), followed by one standard high-dose methotrexate (MTX) course, followed by another intense course for HR ALL (HR-2?) and a second standard high-dose MTX course.;Secondary Objective: Here we aim to analyze:
?the pEFS and cumulative incidence of relapse/CNS-relapse as compared to study EURO-LB 02
?overall survival (pOS) defined as time from diagnosis to death of any cause or to date of last contact for patients alive as compared to study EURO-LB 02
?treatment related mortality in the randomized arms and compared to study EURO-LB 02
?adverse event and severe adverse event profile in specific protocol elements or randomized arms and during follow-up and compared to study EURO-LB 02
?feasibility and results of risk group stratification
?feasibility of minimal residual disease evaluation in children and adolescents with LBL
?identification of prognostic molecular markers for T-LBL which can be added to the risk group stratification system in a subsequent trial(PTEN mutations and deletions, PIK3CA, PIK3R1, KRAS, NRAS, chromosome 6q alterations, status of TRG locus and further molecular markers identified in the targeted panel of molecular markers for T-LBL).;Primary end point(s): Primary endpoints of randomization 1:
For the randomized question 1 the cumulative incidence of relapse with involvement of the CNS (CNS-relapse, pCICR) is the primary endpoint. The time to relapse is the time from randomization to the first relapse or the date of last follow-up. Other events will be taken into account as competing events.
CNS-relapse is defined as follows:
?=5/?l nucleated cells in CSF and morphologically unequivocal evidence of lymphoblasts
?histologically proven LBL in cases of intracranial mass without evidence of blasts in CSF
Primary endpoints of randomization 2
For the randomized question 2 the estimated probability of event-free survival (pEFS) is the primary endpoint. The pEFS is the time from randomization to the first event or date of last follow-up.
The following occurrences are defined as an event
?non-response
?disease progression/relapse
?secondary malignancy
?death from any cause;Timepoint(s) of evaluation of this end point: Interim analysis:
- First randomization: intended to be performed after 3 years
- Second randomization: intended to be performed after 3 and 5 years
Final analysis:
- intended to be performed 3 years after randomization of the last patient (ICTRP)
Secondary end point(s): The secondary endpoints of the trial LBL 2018 are the following
?survival (pOS) defined as time from diagnosis to death due to any cause or to the date of last contact for patients alive
?frequency of treatment-related toxicity and mortality overall and in specific protocol elements, randomized arms and during follow-up
?frequency of adverse events of interest and severe adverse events overall
?rate of evaluable patients for risk group stratification
?cumulative incidence of relapses in association with molecular markers of the published genetic classifier in T-LBL patients and molecular markers identified in the targeted panel of molecular markers for T-LBL.
?cumulative incidence of relapses in association with minimal residual disease results.;Timepoint(s) of evaluation of this end point: Final analysis: intended to be performed 3 years after randomization of the last patient (ICTRP)
