The purpose of this study is to evaluate the efficacy and safety of PCI-32765 (ibrutinib) administered in combination with either bendamustine and rituximab (BR) or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in adult participants with previously treated indolent Non-Hodgkin lymphoma.
This is a randomized (individuals assigned to study treatment by chance), double-blind (individuals and study personnel will not know the identity of study treatments), placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial)-controlled study in approximately 400 adult participants with follicular lymphoma or marginal zone lymphoma. The study will include the following phases: Screening, Treatment, and a Post-treatment Follow-up. Eligible participants will be randomly assigned in a 1:1 ratio to either treatment Arm A (background immune-chemotherapy + placebo) or treatment Arm B (background immune-chemotherapy + 560 milligram \[mg\] of ibrutinib). All participants will receive 6 cycles of background immune-chemotherapy with either BR or R-CHOP in combination with either placebo (Arm A) or ibrutinib (Arm B). Selection of background immune-chemotherapy will be based on prior treatment history and cardiac function. After completion of background immune-chemotherapy, study drug (ibrutinib or placebo) will continue until disease progression, unacceptable toxicity, or study end, whichever comes first. Assessment of tumor response and progression will be conducted in accordance with the Revised Response Criteria for Malignant Lymphoma. Serial pharmacokinetic (study of what a drug does to the body) blood samples will be collected. Safety will be assessed throughout the study.

Primary Analysis: Progression Free Survival (PFS): Stratified Analysis
PFS was defined as duration (in months) from the date of randomization to the date of disease progression or relapse from complete response (CR) or death, whichever was first reported. PFS was assessed by the investigator based on the 2007 Revised Response Criteria for Malignant Lymphoma. Disease progression was defined as any new lesion or increase by greater than or equal to (\>=) 50 percent (%) of previously involved sites from nadir disease progression criteria: Appearance of new nodal lesion 1.5 centimeters (cm) in any axis, 50% increase in sum of product of diameters (SPD) of greater than (\>) 1 node or 50% increase in longest diameter of previously identified node 1 cm in short axis. Participants who were progression-free and alive or had unknown status were censored at the last tumor assessment. Kaplan-Meier method was used for the analysis. Stratification factors were used for the analysis.
Time frame: Up to 8 years

Criteria for CR: disappearance of all evidence of disease; mass of any size permitted if positron emission tomography (PET) negative; regression to normal size on CT; spleen and liver: not palpable, nodules disappeared; bone marrow: infiltrate cleared on repeat biopsy and no new sites of disease detected during assessment. Kaplan-Meier method was used for the analysis. Stratification factors were used for the analysis.

Primary Analysis: Time to Worsening (TTW) in the Lymphoma (Lym) Subscale of the Functional Assessment of Cancer Therapy - Lymphoma Subscale (FACT-LymS) Questionnaire
Time-to-worsening in the Lymphoma subscale of the FACT-Lym was defined as the time (in months) from the date of randomization to the start date of the worsening of participant symptoms. Worsening was defined by a 5-point decrease from baseline in participant symptoms. FACT-Lym Lymphoma subscale contains 15 questions, scores from 0 to 4 for each question (0 = not at all, 1 = a little bit, 2 = some what, 3 = quite a bit and 4 = very much, where the higher score indicated worse condition). Lymphoma subscale score is the total of reverse scores, range 0 to 60. Higher scores indicate a better quality of life.

Number of Participants With Treatment-emergent Adverse Events (TEAEs)
Number of participants with TEAEs were reported. Adverse event (AE) was defined as any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE did not necessarily have a causal relationship with the pharmaceutical/biological agent under study. TEAEs were defined as adverse events with onset or worsening on or after date of first dose of study treatment up to and including 30 days after date of last dose of study medication.
