Summary:

      The primary objective of the study is to evaluate the safety of idelalisib in combination
      with an anti-CD20 monoclonal antibody (mAb), a chemotherapeutic agent, a mammalian target of
      rapamycin (mTOR) inhibitor, a protease inhibitor, an antiangiogenic agent, and/or an
      immunomodulatory agent in participants with relapsed or refractory indolent B-cell
      non-Hodgkin lymphoma (NHL), mantle cell lymphoma (MCL), or chronic lymphocytic leukemia
      (CLL).
    

Eligibility criteria:

        Key Inclusion Criteria:

             a standard regimen)

          -  Disease status requirement:

               -  For CLL patients, symptomatic disease that mandates treatment as defined by the
                  International Workshop on Chronic Lymphocytic Lymphoma (IWCLL) 2008 criteria

               -  For indolent NHL and MCL patients, measurable disease by CT scan defined as at

             (ie, latex condom, cervical cap, diaphragm, abstinence, etc.) for the entire duration
             of the study.

               -  For Cohort 7 only: Women of child bearing potential must have 2 negative
                  pregnancy tests prior to starting lenalidomide.

             given disease (idelalisib, bendamustine, rituximab, ofatumumab, fludarabine,
             everolimus, bortezomib, or chlorambucil), according to the clinical judgment of the
             investigator

          -  Patients with atypical immunophenotype with t(11:14) translocation or cyclin D1
             over-expression (CLL patients only)

          -  Had radiotherapy, radioimmunotherapy, biological therapy, chemotherapy, or treatment
             with an investigational product within 4-weeks prior to the baseline disease status
             tests

          -  Had treatment with a short course of corticosteroids for symptom relief within 1-week
             prior to the baseline disease status tests

          -  Has had an allogeneic hematopoietic stem cell transplant
