  Purpose

The purpose of this study is to provide treatment for patients who have chronic lymphocytic leukemia (CLL), and to compare the use of rituximab added to fludarabine+cyclophosphamide (FC) with FC alone, to determine if rituximab lengthens the time a patient remains free of leukemia symptoms.

Primary Outcome Measures:
  • Progression-free Survival (PFS) as Assessed by the Independent Review Committee (IRC) [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Progression-free survival as assessed by the IRC was defined as the time between randomization and the date of first documented disease progression, relapse after response, or death from any cause, whichever came first. Patients without a PFS event were censored at their last tumor assessment date.

  • Number of Participants With Progression-free Survival (PFS) Events Assessed by the Independent Review Committee (IRC) [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Progression-free survival as assessed by the IRC was defined as the time between randomization and the date of first documented disease progression, relapse after response, or death from any cause (PFS events), whichever came first. Patients without a PFS event were censored at their last tumor assessment date.

  • Final Analysis: Time to Progression-Free Survival Event [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Time to progression-free survival (PFS) event was defined as the time between randomization and the date of first documented PFS event: disease progression, relapse or death by any cause, whichever came first.


Secondary Outcome Measures:
  • Overall Survival (OS) [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Overall survival was determined from the date of randomization to the date of death irrespective of cause. Patients who had not died at the time of the final analysis (clinical data cut-off) were censored at the date of the last contact.

  • Number of Participants With Overall Survival (OS) Events [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Overall survival was determined from the date of randomization to the date of death (OS event) irrespective of cause. Patients who had not died at the time of the final analysis (clinical data cut-off) were censored at the date of the last contact.

  • Event-free Survival (EFS) [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Event free survival was measured from the day of randomization to the date of first documented PD, relapse after response, start of a new treatment or death from any cause. Patients without an EFS event were censored at their last tumor assessment date.

  • Number of Participants With Event-free Survival (EFS) Events [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Event free survival was measured from the day of randomization to the date of first documented Progressive Disease (PD), relapse after response, start of a new treatment or death from any cause (EFS events). Patients without an EFS event were censored at their last tumor assessment date.

  • Disease-free Survival (DFS) [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Disease free survival was defined for all patients with a best overall response (BOR) of Complete Response (CR) and measured the time from first documented CR in a sequence of consecutive CRs until documented disease progression, relapse or death from any cause. Patients without a DFS event at the time of the analysis (clinical data cut-off) were censored at their last tumor assessment date.

  • Number of Participants With Disease-free Survival (DFS) Events [ Time Frame: Mean observation time at time of analysis was approximately 26 months ] [ Designated as safety issue: No ]
    Disease free survival was defined for all patients with a best overall response (BOR) of Complete Response (CR) and measured the time from first documented CR in a sequence of consecutive CRs until documented disease progression, relapse or death from any cause (DFS events). Patients without a DFS event at the time of the analysis (clinical data cut-off) were censored at their last tumor assessment date.

  • Final Analysis: Time to Overall Survival Event [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Overall survival (OS) was determined from the date of randomization to the date of death (OS event) irrespective of cause.

  • Final Analysis: Time to Event-Free Survival Event [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Event free survival (EFS) was defined as the time from the day of randomization to the date of first EFS event: documented disease progression, relapse after response, start of a new treatment or death from any cause.

  • Final Analysis: Percentage of Participants With Complete Response [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Complete response was defined as the disappearance of all signs of cancer in response to treatment.

  • Final Analysis: Time to Disease-Free Survival Event [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Time to disease-free survival (DFS) event was defined as the time from first documented response until the first documented DFS event: disease progression, relapse or death from any cause.

  • Final Analysis: Duration of Response [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Duration of response was defined as the time between the date of the earliest qualifying response and the date of disease progression or death due to any cause.

  • Final Analysis: Time to New Chronic Lymphocytic Leukemia (CLL) Treatment [ Time Frame: Median observation time was approximately 5 years ] [ Designated as safety issue: No ]
    Time to new CCL treatment was defined as the time from randomization to the first day of new treatment for CCL or death.
