Brief Summary:
The primary objective of this study is to evaluate the 28-day safety, tolerability, and pharmacokinetics (PK) of idelalisib in Japanese participants with relapsed or refractory indolent non-Hodgkin lymphoma (iNHL) or chronic lymphocytic leukemia (CLL).

Condition or disease Intervention/treatment Phase
Chronic Lymphocytic Leukemia Indolent Non-Hodgkin Lymphoma Follicular Lymphoma Small Lymphocytic Lymphoma Lymphoplasmacytic Lymphoma (With or Without Waldenstrom Macroglobulinemia) Marginal Zone Lymphoma Drug: Idelalisib Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 6 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1b Study to Investigate the Safety, Tolerability, and Pharmacokinetics of Idelalisib in Japanese Subjects With Relapsed or Refractory Indolent B-Cell Non-Hodgkin Lymphomas or Chronic Lymphocytic Leukemia
Actual Study Start Date : October 1, 2014
Actual Primary Completion Date : December 25, 2014
Actual Study Completion Date : October 17, 2017

Arm Intervention/treatment
Experimental: Idelalisib
- Idelalisib cohort: Idelalisib 150 mg in participants with iNHL or CLL
Drug: Idelalisib
Tablet (s) administered orally twice daily
Other Names:
  • Zydelig®
  • GS-1101
  • CAL-101

Primary Outcome Measures :
  1. Type, frequency, severity, timing, and relationship to idelalisib of adverse events (AEs), abnormal laboratory tests, and drug discontinuations due to AEs and serious adverse events (SAEs) [ Time Frame: Up to 28 days ]
    This composite endpoint will measure the overall safety of idelalisib after 28 days of exposure.

  2. PK profile of idelalisib and its major metabolite GS-563117 [ Time Frame: Predose and at 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0, 8.0, and 12.0 hours postdose on Days 1 and 29 ]

    This composite endpoint will measure the plasma PK profile of idelalisib and GS-563117. The following PK parameters will be measured on Days 1 and 29, where applicable:

    • Cmax: maximum observed concentration of drug in plasma
    • Tmax: time of Cmax
    • AUC: concentration of drug over time (area under the plasma concentration versus time curve)

  3. Idelalisib trough and peak plasma concentrations [ Time Frame: Predose and 1.5 hours postdose on Days 8, 15, and 22 ]

Secondary Outcome Measures :
  1. Type, frequency, severity, timing, and relationship to idelalisib of AEs, abnormal laboratory tests, and drug discontinuations due to AEs and SAEs [ Time Frame: Up to 2 years ]
    This composite endpoint will measure the overall safety profile of idelalisib beyond 28 days of exposure.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Key Inclusion Criteria:

  • Subjects with mature B-cell malignancies of indolent non-Hodgkin lymphoma including follicular lymphoma, small lymphocytic lymphoma, lymphoplastic lymphoma, marginal zone lymphoma, and chronic lymphocytic leukemia by World Health Organization classification
  • Must have been born in Japan and must not have lived outside of Japan for > 1 year in the 5 years prior to Day 1.
  • Must be able to trace maternal and paternal ancestry of parents and grandparents as Japanese.
  • Must have been previously treated with at least 1 regimen for iNHL or CLL and currently require treatment.
  • Discontinuation of all therapy (including radiotherapy, chemotherapy, immunotherapy, or investigational therapy) for the treatment of iNHL or CLL ≥ 4 weeks prior to Day 1
  • Eastern Cooperative Oncology Group performance status of 0 or 1
  • Required baseline laboratory data (within 4 weeks prior to Day 1)
  • A negative serum pregnancy test for female subjects of childbearing potential
  • Males and females of childbearing potential who engage in heterosexual intercourse must agree to use protocol-specified method(s) of contraception.
  • In the judgment of the investigator, participation in the protocol offers an acceptable benefit-to-risk ratio when considering current disease status, medical condition, and the potential benefits and risks of alternative treatments for the individual's disease.

Key Exclusion Criteria:

  • Known histological transformation to an aggressive histology
  • Known presence of myelodysplastic syndrome
  • History of iNHL or CLL with central nervous system involvement
  • Life expectancy < 120 days as per investigator assessment
  • History of a nonlymphoid malignancy with the following exceptions:

    • the malignancy has been in remission without treatment for ≥ 5 years prior to Day 1, or
    • carcinoma in situ of the cervix, or
    • adequately treated basal or squamous cell skin cancer or other localized nonmelanoma skin cancer, or
    • surgically treated low-grade prostate cancer, or
    • ductal carcinoma in situ of the breast treated with lumpectomy alone
  • On-going drug-induced liver injury, alcoholic liver disease, nonalcoholic steatohepatitis, primary biliary cirrhosis, extrahepatic obstruction caused by cholelithiasis, cirrhosis of the liver, or portal hypertension
  • History or diagnosis of pneumonitis or interstitial lung disease.
  • On-going inflammatory bowel disease
  • Pregnancy or breastfeeding
  • History of prior allogeneic hematopoietic stem cell or solid organ transplantation
  • Concurrent participation in another therapeutic clinical trial
  • Prior or on-going clinically significant illness, medical condition, surgical history, physical finding, electrocardiogram finding, or laboratory abnormality that, in the investigator's opinion, could adversely affect the safety of the individual or impair the assessment of study results.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
