About

This was an open-label, single-dose study to assess the safety, tolerability, and absorption/distribution kinetics of a single 100 µg dose of fentanyl sublingual spray in opioid-tolerant cancer subjects, with or without oral mucositis.

Full description

RATIONALE: One dose of fentanyl sublingual spray may be effective in relieving pain in opioid-tolerant cancer patients.

PURPOSE: This phase III trial is studying the side effects of fentanyl sublingual spray and to see how well it works in treating opioid-tolerant cancer patients with or without oral mucositis.

OBJECTIVES:

Primary

To compare the absorption/distribution kinetics of a single dose of fentanyl sublingual spray in opioid-tolerant cancer patients with or without oral mucositis.
To evaluate the safety and tolerability of this regimen.

OUTLINE: This is a multicenter study.

Patients fast for at least 8 hours before and at least 4 hours after and no water is allowed for at least 1 hour before and at least 1 hour after study drug administration. Patients receive a single dose of fentanyl sublingual spray while in an upright position in clinical care recliners or beds, and remain in an upright posture for at least 4 hours after administration. Patients are instructed not to swallow for at least 5 minutes after administration and not to expectorate the drug.

After study drug administration, 10 blood samples are collected over a 12-hour period for pharmacokinetic and other analyses.
