The study will evaluate the efficacy and safety of idelalisib (CAL-101, GS-1101) in participants with relapsed of refractory Hodgkin Lymphoma (HL). The primary objective will be to assess the overall response rate.

Eligible patients will initiate oral therapy with idelalisib at a starting dose of 150 mg twice daily. Treatment with idelalisib will continue until tumor progression or unacceptable toxicity.

Primary Outcome Measures:
  • Overall response rate [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Overall response rate (ORR) is defined as the proportion of patients who achieve a confirmed complete response (CR) or partial response (PR) during idelalisib treatment; response definitions will be based on standard criteria.

Secondary Outcome Measures:
  • Duration of response [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Duration of response (DOR) is defined as the interval from the first documentation of PR or CR to the earlier of the first documentation of disease progression or death from any cause.

  • Percent change from baseline in the sum of the product of the greatest perpendicular diameters (SPD) of target lymph nodes as documented radiographically [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  • Change from baseline in fluorodeoxyglucose (FDG) uptake in lymph nodes as assessed by positron-emission tomography (PET) [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  • Time to treatment response [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Time to treatment response (TTR) is defined as the interval from the start of idelalisib treatment to the first documentation of CR or PR.

  • Progression free survival [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Progression free survival (PFS) is defined as the interval from the start of idelalisib treatment to the earlier of the first documentation of disease progression or death from any cause.

  • Time to treatment failure [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Time to treatment failure (TTF) is defined as the interval from the start of idelalisib treatment to the earlier of the first documentation of disease progression, the permanent cessation of idelalisib therapy due to an adverse event, or death from any cause.

  • Changes in health-related quality of life events as reported using the Functional Assessment of Cancer Therapy: Lymphoma (FACT-Lym) questionnaire [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  • Changes in performance status [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Changes in performance status will be assessed using the Karnofsky performance criteria for participants ≥ 16 years of age and the Lansky performance criteria for participants < 16 years of age.

  • Changes in the plasma concentrations of disease-associated chemokines and cytokines [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  • Type, frequency, severity, timing, and relationship to study therapy of any adverse events or abnormalities of physical findings, laboratory tests, or ECGs; drug discontinuations due to adverse events; or serious adverse events [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    This composite endpoint will measure the overall safety profile of idelalisib.

  • Study drug administration as assessed by prescribing records and compliance as assessed by quantification of used and unused drug [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
  • Idelalisib trough and peak plasma concentrations [ Time Frame: Predose and 1.5 hours postdose ] [ Designated as safety issue: No ]

Inclusion Criteria:

  • Age ≥ 12 years
  • Karnofsky performance score of ≥ 60 (Eastern Cooperative Oncology Group [ECOG] performance score of 0, 1, or 2)
  • Histologically confirmed diagnosis of classic HL (ie, nodular sclerosis, mixed cellularity, lymphocyte depleted, and or lymphocyte rich types)
  • Nodal HL that shows fluorodeoxyglucose [FDG] avidity (defined as focal or diffuse FDG uptake above background in a location incompatible with normal anatomy or physiology), and is measurable (defined as the presence of ≥ 1 nodal lesion that measures ≥ 2 cm in a single dimension as assessed by CT, PET/CT, or magnetic resonance imaging [MRI])
  • Relapsed or refractory HL after prior myeloablative therapy with autologous stem cell transplantation (ASCT) or after ≥ 2 prior chemotherapy-containing regimens and no curative option with conventional therapy
  • Discontinuation of all radiotherapy or chemotherapy for the treatment of HL greater than or equal to 3 weeks before initiation of study treatment and discontinuation of all radioimmunotherapy for HL (Visit 2)
  • All acute toxic effects (excluding alopecia, neurotoxicity, or anemia) of any prior antitumor therapy resolved to Grade ≤ 2 before initiation of study treatment (Visit 2)
