This is a long-term safety extension study of idelalisib (GS-1101; CAL-101) in patients with hematologic malignancies who complete other idelalisib studies. It provides the opportunity for patients to continue treatment as long as the patient is deriving clinical benefit. Patients will be followed according to the standard of care as appropriate for their type of cancer. The dose of idelalisib will generally be the same as the dose that was administered at the end of the prior study, but may be titrated up to improve clinical response or down for toxicity. Patients will be withdrawn from the study if they develop progressive disease, unacceptable toxicity related to idelalisib, or if they no longer derive clinical benefit in the opinion of the investigator.

Primary Outcome Measures:
  • Overall response rate [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Overall response rate (ORR) is defined as the proportion of participants who achieve complete response (CR), partial response (PR), or minor response (MR; for Waldenström's macroglobulinemia [WM] only).

  • Safety as assessed by incidence of grade ≥ 3 adverse events according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.03 [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Duration of Response [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Duration of response (DOR) is defined as the interval from the first documentation of CR, PR, or MR (for WM) to the earlier of the first documentation of definitive disease progression or death from any cause.

  • Progression-free survival [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Progression-free survival (PFS) is defined as the interval from enrollment in the parent study to the earlier of the first documentation of definitive disease progression (excluding lymphocytosis alone) or death from any cause.

  • Overall survival [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Overall survival (OS) is defined as the interval from the start of study treatment in the parent study to death from any cause.

  • Time to response [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Time to response (TTR) is defined as the interval from first dose to the first documentation of CR or PR.

Enrollment: 202
Study Start Date: March 2010
Estimated Study Completion Date: March 2017
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Idelalisib
Participants will receive up to 300 mg of idelalisib once or twice daily until disease progression or unacceptable toxicity.
