Study Arms:
- Part 1: Ibrutinib (Type: EXPERIMENTAL): The first 2 participants enrolled in each age group (1-5 years, 6-11 years and 12-17 years) will receive starting dose of Ibrutinib 240 milligram per square meter (mg/m\^2) for the first cycle, followed by dose escalation at the start of Cycle 2 as long as all pharmacokinetic assessments are within the expected range and there are no safety concerns. For participants being treated at 240 mg/m\^2 dose level during the first cycle, the maximum dose should not exceed a total of 420 mg/day. All participants will receive rituximab, ifosfamide, carboplatin, etoposide and dexamethasone (RICE) or ituximab, vincristine, ifosfamide, carboplatin, idarubicin and dexamethasone (RVICI) background therapy (investigator's choice), during treatment phase. Participants with PR or better only will receive Ibrutinib for 3 cycles or until PD, unacceptable toxicity or until initiating antilymphoma therapy or a conditioning regimen for stem cell transplantation during post-treatment phase.
- Part 2: Ibrutinib (Type: EXPERIMENTAL): Participants will either receive ibrutinib and RICE/RVICI background therapy or RICE/RVICI background therapy alone, until 3 cycles are completed or until PD or unacceptable toxicity during the treatment phase. Participants who received ibrutinib and RICE/RVICI background therapy and with PR or better only will receive ibrutinib alone for 3 cycles during post-treatment phase.

Based on this trial design, predict the completion outcome and termination type (if applicable).
