E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate whether the administration of vincristine (VCR) in children with acute lymphoblastic leukemia (ALL) by one-hour infusions leads to less peripheral neuropathy (PNP) compared to the administration by bolus injections. |
Deze studie heeft tot doel te onderzoeken of de toediening van vincristine (VCR) bij kinderen met ALL door middel van één-uurs-infusen leidt tot minder PNP dan toediening door middel van bolus-injecties. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate whether the administration of VCR in children with ALL by one-hour infusions leads to better self-reported quality of life compared to the administration by bolus injections.
• To evaluate whether the administration of VCR in children with ALL by one-hour infusions leads to equal or better treatment efficacy compared to the administration by bolus injections.
• To compare the pharmacokinetic parameters of patients receiving both administration methods and to relate these parameters to the degree of PNP.
• To validate or confirm the relationship between SNPs known to be associated with VCR-induced PNP (either through influencing pharmacokinetics of VCR or through genetically increased susceptibility) and the degree of PNP of patients receiving both administration methods. |

E.2.3 | Trial contains a sub-study | No |

|
|

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome of the study is peripheral neuropathy (PNP). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
PNP will be evaluated at seven points in time: at baseline, three to four times during the two years of VCR-therapy, at the end of therapy, and 6 months after the end of VCR-therapy. |
|
E.5.2 | Secondary end point(s) |
Secondary parameters include quality of life, therapeutic effectiveness, and pharmacokinetic and genetic outcomes. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Quality of life and pharmacokinetic measures: three to four times during VCR-therapy, 1 time at the end of therapy, 1 time at 6 months after the end of VCR-therapy.
Therapeutic effectiveness: thorough monitoring during the study by evaluating residual disease (MRD), cumulative incidence of relapses, event-free survival (EFS) and overall survival (OS). These data concern readily available data which will be provided by the indivicual participating centers.
Genetics: exome sequencing at one time point. |
