• Status: Terminated
• Trial end date: 2016-05-13

Summary

The primary objective of this study is to evaluate the effects of idelalisib with obinutuzumab versus the combination of chlorambucil and obinutuzumab on progression-free survival (PFS) in participants with previously untreated chronic lymphocytic leukemia (CLL).

An increased rate of deaths and serious adverse events (SAEs) among participants with front-line CLL and early-line indolent non-Hodgkin lymphoma (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 those studies in agreement with the DMC recommendation and in consultation with the US Food and Drug Administration (FDA). All front-line studies of idelalisib, including this study, were also terminated.
