  Purpose

The Phase 2, open-label, single-arm, efficacy, safety, and pharmacodynamic study is to evaluate the efficacy and safety of idelalisib (CAL-101, GS-1101) in patients 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 per day. Treatment with idelalisib will continue until tumor progression or unacceptable toxicity.

Primary Outcome Measures:
  • Overall Response Rate during treatment with idelalisib based on standard criteria [ Time Frame: every 8-12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Duration of Response [ Time Frame: every 8-12 weeks ] [ Designated as safety issue: No ]
  • Change from baseline in the sum of the product of the greatest perpendicular diameters of the target lymph nodes [ Time Frame: every 8-12 weeks ] [ Designated as safety issue: No ]
  • Change from baseline in fluorodeoxyglucose (FDG) update in lymph nodes as assessed by positron-emission tomography (PET) [ Time Frame: at baseline, week 8, and to confirm CR ] [ Designated as safety issue: No ]
  • Time to Treatment Response [ Time Frame: every 8-12 weeks ] [ Designated as safety issue: No ]
  • Progression Free Survival [ Time Frame: every 8-12 weeks ] [ Designated as safety issue: No ]
  • Time to Treatment Failure [ Time Frame: every 8-12 weeks ] [ Designated as safety issue: No ]
  • Changes in health-related quality of life events [ Time Frame: every 4-12 weeks ] [ Designated as safety issue: No ]
  • Changes in performance status [ Time Frame: every 4-12 weeks ] [ Designated as safety issue: No ]
  • In pretreatment lymph nodes, PI3K pathway activation as assess by flow cytometry for pAkt and gene expression profiling using bead arrays [ Time Frame: baseline ] [ Designated as safety issue: No ]
  • Changes in plasma concentrations of disease-associated chemokines and cytokines [ Time Frame: every 4-12 weeks ] [ Designated as safety issue: No ]
  • Overall safety profile of idelalisib [ Time Frame: every 2-12 weeks ] [ Designated as safety issue: No ]
  • Study Drug administration and compliance [ Time Frame: every 4-12 weeks ] [ Designated as safety issue: No ]
  • Idelalisib plasma exposure over time [ Time Frame: every 4-8 weeks ] [ Designated as safety issue: No ]

Criteria

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)
  • For men and women of childbearing potential willingness to abstain from sexual intercourse or employ an effective method of contraception during the study drug administration and follow-up periods
  • Willingness and ability to provide written informed consent and to comply with protocol requirements

Exclusion Criteria:

  • Known active central nervous system or leptomeningeal lymphoma
  • History of a non-lymphoma malignancy except for the following: adequately treated local basal cell or squamous cell carcinoma of the skin, cervical carcinoma in situ, superficial bladder cancer, localized prostate cancer, other adequately treated Stage 1 or 2 cancer currently in complete remission, or any other cancer that has been in complete remission for ≥ 5 years
  • Evidence of ongoing systemic bacterial, fungal, or viral infection (excluding viral upper respiratory tract infections) at the time of initiation of study treatment (Visit 2)
  • Pregnancy or breastfeeding
  • Ongoing alcohol or drug addiction
  • Known history of drug-induced liver injury, chronic active hepatitis C virus (HCV), chronic active hepatitis B virus (HBV), alcoholic liver disease, non-alcoholic steatohepatitis, primary biliary cirrhosis, ongoing extrahepatic obstruction caused by stones, cirrhosis of the liver or portal hypertension
  • History of prior allogeneic bone marrow progenitor cell or solid organ transplantation
  • Ongoing immunosuppressive therapy, including systemic corticosteroids.
  • Prior therapy with idelalisib
  • Exposure to another investigational drug within 3 weeks prior to start of study treatment
  • Concurrent participation in another therapeutic treatment trial
  • Prior or ongoing clinically significant illness, medical condition, surgical history, physical finding, ECG finding, or laboratory abnormality that, in the investigator's opinion, could affect the safety of the patient; alter the absorption, distribution, metabolism or excretion of the study drug; or impair the assessment of study results
  • Prior therapy with any drug that inhibits Akt, Bruton tyrosine kinase (BTK), Janus kinase (JAK), mammalian target of rapamycin (mTOR), phosphatidylinositol 3 kinase (PI3K) (including idelalisib), or spleen tyrosine kinase (SYK)
