Brief summary

The purpose of this study is to confirm that the pharmacokinetics of ibrutinib in pediatric participants is consistent with that in adults (part 1) and to assess efficacy (event-free survival \[EFS\]) of ibrutinib in combination with rituximab, ifosfamide, carboplatin, and etoposide (RICE) or rituximab, vincristine, ifosfamide, carboplatin, and idarubicin (RVICI) background therapy compared to RICE or RVICI background therapy alone (part 2).

Detailed description

This is a Phase 3, randomized (study medication assigned to participants by chance), open-label (identity of study drug will be known to participant and study staff), controlled study which consists of two parts: Part 1 and Part 2. The Part 1 is a pharmacokinetic run-in part, which will be conducted before starting the randomized part (Part 2) of the study and Part 2 is a randomized and open-label study. Part 1 and Part 2 of the study will be conducted in 3 phases: a Pretreatment (Screening) Phase (Up to 14 days before administration of study drug), a Treatment Phase, and a Posttreatment Phase. The Treatment Phase will extend from enrollment (in Part 1) or randomization (in Part 2) until 1 of the following: 1) completion of 3 cycles of therapy, 2) transplantation, if clinically indicated, or 3) progressive disease (PD), whichever comes first. The Posttreatment Phase will continue until death, loss to follow up, consent withdrawal, or study end, whichever occurs first. The end of study is defined as when approximately 60 event-free survival (EFS) events have occurred in Part 2 (death, disease progression, or lack of complete response \[CR\] or partial response \[PR\] after 3 cycles of treatment based on blinded independent event review), or the sponsor terminates the study, whichever comes first. Participants in Part 1 will be 1 to less than (\<) 18 years old. Participants in Part 2 will be 1 to 30 years old. Participants will be primarily evaluated for pharmacokinetics in part 1 and efficacy (EFS) of ibrutinib in combination with RICE or RVICI background therapy compared to RICE or RVICI background therapy alone in part 2. Participants' safety will be monitored throughout the study.

As planned in protocol, the PK parameters were presented per dose group as dosing was dependent on age.
Part 1: Apparent (Oral) Plasma Clearance (CL/F) of IbrutinibUp to Cycle 3 (each cycle of 21 or 28 days)CL/F is defined as apparent plasma clearance of ibrutinib.

Transcripts per million (TPM) is a normalization method for RNA-sequencing, which means for every 1,000,000 RNA molecules in the RNA-sequencing tumor FFPE sample, x came from this gene/transcript.

Part 1 and Part 2: Visual Analog Scale (VAS) Score for PalatabilityDay 1 of Cycle 1 and Cycle 3Palatability of ibrutinib was measured by using a VAS. The scale is a 5-point visual analog scale incorporating a facial hedonic scale designed to span pediatric ages and levels of participant comprehension with a score range of 1 to 5, where 1 represents best score and 5 is worst palatability.
