Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Males or females 17 years of age or older
  • Stable cancer-related pain.
  • Are receiving a stable, fixed-schedule oral opioid regimen equivalent to 60 to 1000 mg of oral morphine per day or transdermal fentanyl therapy equivalent to 50 to 300 µg/h, and are on a stable dose of opioid medication for relief of breakthrough pain for at least 14 days prior to screening.

  • Have received strontium 89 therapy within 60 days prior to entering the study.
  • Have received anti-neoplastic therapy within 2 weeks of study entry that, in the investigator's opinion, will influence assessment of breakthrough pain
