  • response rates
  • time to failure to maintain response
  • quality of life as measured by the SWN-S and SF-36
  • cognitive functioning as measured by the MOS
  • sexual functioning as measured by the GISF
  • health resource utilization and resource utilization costs
  • hospitalization time
  • treatment emergent adverse events
  • EPS as measured by the Simpson-Angus, Barnes, and AIMS
  • laboratory values
  • vital signs
