  • Previously received at least 1 prior line of systemic therapy with documented progression, and there is no further effective standard anticancer therapy available.
  • Willing to undergo an incisional or excisional lymph node or tissue biopsy or to provide a lymph node or tissue biopsy from the most recent available archival tissue.
  • Life expectancy > 3 months.

  • Adequate hematologic, hepatic, and renal function.
Exclusion Criteria

  • Histologically confirmed, rare non-Hodgkin's B-cell subtypes.
  • History of central nervous system lymphoma (either primary or metastatic) or leptomeningeal disease.
  • Prior treatment with idelalisib, other selective PI3Kδ inhibitors, or a pan-phosphatidylinositol 3 kinase (PI3K) inhibitor.
  • Allogeneic stem cell transplant within the last 6 months or autologous stem cell transplant within the last 3 months before the date of the first dose of study drug.

Primary Outcome Measures
NameTimeMethod
Number of participants with treatment-emergent adverse events (TEAEs)Up to approximately 1 year

TEAE defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug.

Secondary Outcome Measures
NameTimeMethod
Changes in pharmacodynamic (PD) markers of B-cell activation in plasmaUp to 24 weeks

Markers of B-cell activation (eg, B-cell activating factor, interleukin-10, B-cell attracting chemokine) and other plasma analytes will be analyzed for correlation with safety and clinical outcome.

Objective response rateUp to approximately 1 year

Defined as the percentage of subjects with complete response (CR)/complete metabolic response (CMR) and partial response (PR)/ partial metabolic response (PMR), as determined by investigator assessment of response according to response criteria for lymphomas.

Duration of responseUp to approximately 1 year

Defined as the time from first documented evidence of CR/CMR or PR/PMR until disease progression or death from any cause among subjects who achieve an objective response.

Progression-free survivalUp to approximately 1 year

Defined as the time from the date of the first dose of study drug until the earliest date of disease progression or death from any cause.
