Overview
Brief 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).
