简要总结
This protocol is designed to assess the efficacy and safety of inotuzumab ozogamicin given with rituximab compared to a defined investigator's choice therapy. Subjects will be randomized to one of these two arms of the study.
详细描述
On January 14th 2009, enrollment in the study was discontinued because of poor enrollment and because it was unlikely that the study would meet the estimated enrollment of approximately 978 subjects. The decision was not prompted by the identification of any safety signals in this or other studies. Active treatment and follow-up of the already enrolled subjects was continued. On July, 22th 2010 , the study was amended to shorten the long-term follow-up to one year after active treatment.

结局指标
主要结局
Progression-Free Survival (PFS)
时间窗: Baseline until disease progression or death or up to 1 year after last dose of study drug
PFS was defined as the time from randomization to disease progression or death due to any cause, whichever occurred first, censored at the last tumor evaluation date. PFS calculated as (Months) = (first event date minus randomization date plus 1) divided by 30.44.
