| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
Analysis Study 1
 To evaluate whether the addition of ibrutinib to rituximab will result in prolongation of progression-free survival (PFS) when compared with rituximab alone in treatment naïve subjects with follicular lymphoma
 
 Discontinuation Analysis Study
 For subjects who are re-randomized for Part 2, to evaluate whether continuous treatment with ibrutinib will result in prolongation of PFS when compared with finite treatment with ibrutinib | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
Analysis Study 1
 *  During Part 1, to evaluate whether the addition of ibrutinib to rituximab will result in improvement in investigator-assessed CR rate and ORR when compared with rituximab alone in treatment naïve subjects with follicular lymphoma
 * To evaluate whether the addition of ibrutinib to rituximab will result in
 a reduction in infusion-related reactions
 *  To evaluate whether the addition of ibrutinib to rituximab will result in prolongation of OS (Arm A vs. Arm B) through Part 2
 *  To evaluate the safety and tolerability of ibrutinib combined with rituximab compared to rituximab alone in treatment naïve subjects with follicular lymphoma
 
 Discontinuation Analysis Study
 *  To evaluate the long-term safety and tolerability of ibrutinib after completing the rituximab maintenance in treatment naïve subjects with follicular lymphoma |

| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  |

 have one or more comorbidities.
 * Meets one or more Groupe d'Etude des Lymphomes Folliculaire (GELF)
 criteria.
