Treatment: Drugs: Idasanutlin
Participants received idasanutlin film-coated tablets orally at a starting dose of 100 mg daily on Days 1 to 5 of each 28-day cycle. Escalation was to occur in at least 50-mg increments, and daily doses greater than or equal to (=) 400 mg will be split into twice daily dosing.

Treatment: Drugs: Obinutuzumab
Participants received a fixed dose of obinutuzumab 1000 mg intravenous (IV) infusion to be given on Days 1, 8 and 15 of Cycle 1 and on Day 1 of Cycles 2 to 6 (1 cycle = 28 days). For eligible participants with FL, post-induction treatment was to be given at a dose of 1000 mg via IV infusion on Day 1 once every 2 months for a maximum of up to 24 months.

Treatment: Drugs: Rituximab
Participants received a fixed dose of rituximab, 375 mg/m^2 IV infusion on Day 1 of Cycles 1-6. Post-induction treatment for eligible participants was to be given at a dose of 375 mg/m^2 IV infusion on Day 1 of every other month for up to 6 months, until disease progression or unacceptable toxicity.

Summary
Brief summary
This is a open-label, multicenter, non-randomized, study to evaluate the safety, efficacy,
and pharmacokinetics of idasanutlin in combination with obinutuzumab in participants with R/R
FL and rituximab in combination with idasanutlin in R/R DLBCL. The study will include an
initial dose-escalation phase followed by an expansion phase. The dose-escalation phase is
designed to determine the recommended phase 2 dose (RP2D) for idasanutlin in combination with
obinutuzumab for FL and in combination with rituximab for DLBCL. The expansion phase is
designed to further assess the safety and efficacy of obinutuzumab in combination with
idasanutlin at the RP2D with the selected regimen in participants with R/R FL and of
rituximab in combination with idasanutlin at the RP2D in participants with R/R DLBCL.
