On June 25, 2009, the independent Data Monitoring Committee (DMC) reviewed the progress of Study A6181122. The DMC determined Study A6181122 had met pre-specified futility criteria and was unlikely to meet its primary endpoint to demonstrate a statistically significant improvement in progression-free survival (PFS) in patients treated with sunitinib plus FOLFIRI versus placebo plus FOLFIRI. No new safety findings were noted. Pfizer notified clinical trial investigators involved in the study and regulatory agencies of these findings. Patients receiving benefit on treatment as determined by the investigator may remain on study.
