Detailed Description:
PF-3512676 dosing was stopped 20 June 2007 in response to DSMC recommendation to close the trial, citing lack of efficacy concerns as the primary reason with a safety issue (thrombocytopenia) also contributing to the decision. Subjects were allowed to complete standard of care treatment/survival follow-up. Data collection was completed on 25 June 2008.
