Overall Safety [ Time Frame: Baseline to Month 12 ] [ Designated as safety issue: No ]
Overall safety profile of each study treatment regimen will be characterized by the type, frequency, severity, timing of onset, duration, and relationship to study therapy of any adverse events or abnormalities of laboratory tests, serious adverse events, or adverse events leading to discontinuation of study drug.
Overall Response Rate [ Time Frame: 12 months ] [ Designated as safety issue: No ]

  • Tumor Control [ Time Frame: Baseline to Month 12 ] [ Designated as safety issue: No ]
    Tumor control will be assessed by progression-free survival, overall response rate, lymph node response rate, complete response rate, time to response, duration of response, percent change in lymph node area, splenomegaly response rate, hepatomegaly response rate, absolute lymphocyte count (ALC) response rate, platelet response rate, hemoglobin response rate, and neutrophil response rate.
  • Patient Well-Being [ Time Frame: Baseline to Month 12 ] [ Designated as safety issue: No ]
    Patient well-being will be assessed by overall survival, change from baseline in health-related quality of life (HRQL) domain and symptom scores based on the Functional Assessment of Cancer Therapy: Leukemia (FACT-Leu), and changes from baseline in Karnofsky performance status.
  • Pharmacodynamic [ Time Frame: Baseline to Month 6 ] [ Designated as safety issue: No ]
    Pharmacodynamics will be assessed by changes from baseline in phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway activation and changes from baseline in the plasma concentrations of disease-associated chemokines and cytokines.
  • Patient Well-Being (Health related quality of life questionnaires) [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Disease related biomarkers [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Pharmacokinetic [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Pharmacokinetic to measure peak plasma concentrations (Cmax) as well as the area under the plasma concentration versus time curve (AUC).
  • Incidence of adverse events [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Health Resource Utilization [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Extension Study of Idelalisib for Patients With Chronic Lymphocytic Leukemia Who Participated in GS-US-312-0116
A Phase 3, Double-Blind Extension Study Evaluating the Efficacy and Safety of Two Different Dose Levels of Single-Agent Idelalisib (GS-1101) for Previously Treated Chronic Lymphocytic Leukemia
This study (GS-US-312-0117) is a multicenter, 2-arm, double-blind, parallel-group extension study that is a companion study to Study GS-US-312-0116, to evaluate the effect of idelalisib on the onset, magnitude, and duration of tumor control.
