NCT01569295
First received: March 27, 2012
Last updated: September 5, 2014
Last verified: September 2014
  Purpose

This Phase 3, randomized, double-blind, placebo-controlled study is to evaluate the effect of idelalisib on the onset, magnitude, and duration of tumor control. Eligible patients will be randomized with a 1:1 ratio into 1 of the 2 treatment arms to receive either idelalisib or placebo. All subjects will be administered bendamustine and rituximab.

Primary Outcome Measures:
  • Progression-Free Survival [ Time Frame: Up to 30 months ] [ Designated as safety issue: No ]
    Progression-free survival (PFS) is defined as the interval from randomization to the earlier of the first documentation of definitive disease progression or death from any cause.


Secondary Outcome Measures:
  • Overall Response Rate [ Time Frame: Up to 30 months ] [ Designated as safety issue: No ]
    Overall response rate (ORR) is defined as the proportion of participants who achieve a complete response or partial response.

  • Lymph Node Response Rate [ Time Frame: Up to 30 months ] [ Designated as safety issue: No ]
    Lymph node response rate is defined as the proportion of participants who achieve a ≥ 50% decrease from baseline in the sum of the products of the greatest perpendicular diameters (SPD) of index lesions.

  • Overall Survival [ Time Frame: Up to 30 months ] [ Designated as safety issue: No ]
    Overall survival (OS) is defined as the interval from randomization to death from any cause.

  • Complete Response Rate [ Time Frame: Up to 30 months ] [ Designated as safety issue: No ]
    Complete response (CR) rate is defined as the proportion of participants who achieve a CR.
