Brief Summary:

The primary objective of this study is to evaluate overall response rate (ORR) following treatment with idelalisib plus rituximab in participants with previously untreated chronic lymphocytic leukemia (CLL) with 17p deletion.

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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Overall Response Rate
    Overall response rate (ORR) was defined as the proportion of participants who achieve a confirmed complete or partial response. ORR was to be assessed by an independent review committee (IRC).


Secondary Outcome Measures :
  1. Duration of Response
    Duration of response (DOR) was defined as the interval from the first documentation of confirmed complete response or partial response (by IRC) to the first documentation of definitive disease progression or death from any cause. Definitive disease progression is chronic lymphocytic leukemia (CLL) progression based on standard criteria, excluding lymphocytosis alone.

  2. Nodal Response Rate
    Nodal response rate was defined as the proportion of participants who achieve a 50% decrease from baseline in the sum of the products of the greatest perpendicular diameters of index lesions. Nodal response rate was to be assessed by an IRC.

  3. Complete Response Rate
    Complete response rate was defined as the proportion of participants who achieve a confirmed complete response. Complete response rate was to be assessed by an IRC.

  4. Progression-Free Survival
    Progression-free survival (PFS) was defined as the interval from first dose of study drug to the first documentation of definitive disease progression or death from any cause. Definitive disease progression is CLL progression based on standard criteria, excluding lymphocytosis alone. PFS was to be assessed by an IRC.

  5. Overall Survival
    Overall survival was defined as the interval from the start of study treatment to death from any cause.

  6. Minimal Residual Disease Negativity Rate at Week 36
    Minimal residual disease (MRD) negativity rate was defined as the proportion of participants with MRD < 10^-4 assessed by flow cytometry in bone marrow at Week 36 after therapy initiation. For participants receiving the final dose of rituximab after the original scheduled date, the MRD assessment will be performed no fewer than 12 weeks after the last dose of rituximab.
