Brief Summary:

The primary objective of this study is to evaluate the addition of idelalisib to bendamustine/rituximab on progression-free survival (PFS) in adults with previously treated indolent non-Hodgkin lymphoma (iNHL).

An increased rate of deaths and serious adverse events (SAEs) among participants with front-line chronic lymphocytic leukemia (CLL) and early-line iNHL treated with idelalisib in combination with standard therapies was observed by the independent data monitoring committee (DMC) during regular review of 3 Gilead Phase 3 studies. Gilead reviewed the unblinded data and terminated this study in agreement with the DMC recommendation and in consultation with the US Food and Drug Administration (FDA).

Primary Outcome Measures :
  1. Progression-free Survival (PFS)
    PFS is defined as the interval from randomization to the earlier of the first documentation of definitive indolent non-Hodgkin lymphomas (iNHL) disease progression or death from any cause. Definitive iNHL disease progression is progression based on standard criteria. PFS was to be assessed by an independent review committee (IRC).

Secondary Outcome Measures :
  1. Complete Response Rate (CR)
    Complete response rate is defined as the proportion of participants who achieve a complete response. CR rate was to be assessed by an IRC.

  2. Overall Response Rate (ORR)
    Overall response rate is defined as the proportion of participants who achieve a complete response or partial response (or very good partial response (VGPR) or minor response (MR) for participants with Waldenstrom's). ORR was to be assessed by an IRC.

  3. Lymph Node Response Rate
    Lymph node response rate is defined as the proportion of participants who achieve ≥ 50% decrease from baseline in the sum of the products of the greatest perpendicular diameters of index lesions. Lymph node response rate was to be assessed by an IRC.

  4. Overall Survival (OS)
    Overall survival is defined as the interval from randomization to death from any cause.
