The primary objective of this study is to evaluate the effect of the addition of idelalisib
to 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).
