Title Number of Participants With the Indicated Shift From Baseline (BL) in Extreme Fatigue at the Indicated Weeks
Hide Description Extreme fatigue is one of the clinical characteristics of CLL. B symptoms are systemic symptoms of fever, night sweats, weight loss, and extreme fatigue, which can be associated with CLL. Participants who had extreme fatigue at BL, and still had extreme fatigue at Week 1, for example, are represented in the BL, yes; Week 1, yes category. Participants who had extreme fatigue at BL, but did not have extreme fatigue at Week 1 are represented in the BL, yes; Week 1, no category.

Title Serum Hemolytic Complement Titer at Weeks 36 and 48: CH50
Hide Description The CH50 is the serum complement to lyse 50% of sensitized red blood cells; it's is a marker of complement activation. A high CH50 level suggests evidence for complement activation, whereas a low CH50 level suggests lack of complement activation.

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
GSK agreements may vary with individual investigators, but will not prohibit any investigator from publishing. GSK supports the publication of results from all centers of a multi-center trial but requests that reports based on single-site data not precede the primary publication of the entire clinical trial.
