The primary endpoint of the trial will be the 6-month survival rate. Additional efficacy endpoints will be response rate, duration of response and stable disease, and 6-month progression free survival. Responses will be assessed by reduction in radiographically measurable disease as defined by the RECIST criteria. Time to worsening of clinical status will be based on reductions in pain and/or analgesic use and changes in tumor markers (CA 19-9) will also be followed.
