ObjectiveEvaluate analgesic efficacy, functional benefit, and patient satisfaction with fentanyl buccal tablet vs immediate-release oxycodone for breakthrough pain (BTP).DesignRandomized, double-blind, active-controlled crossover trial and 12-week open-label extension.SettingForty-two U.S. sites.PatientsOpioid-tolerant patients with predominantly chronic noncancer pain experiencing BTP.InterventionPatients were randomized to open-label titration periods with fentanyl buccal tablet followed by oxycodone or vice versa for BTP management. After titrating to a successful dose of both medications (single dose providing adequate analgesia without unacceptable adverse events), patients were re-randomized to treat 10 BTP episodes with one medication and 10 with the other.Outcome MeasuresThe primary efficacy measure was pain intensity (PI) difference 15 minutes postdose. Secondary measures included PI difference 5, 10, 30, 45, and 60 minutes postdose; sum of PI differences 30 and 60 minutes postdose; ≥33% and ≥50% reduction in PI; and pain relief. Questionnaires assessed functional status/satisfaction.ResultsOf 213 patients enrolled, 149 achieved a successful dose of both medications; 131 completed the double-blind phase and 112 the open-label phase. PI difference at 15 minutes (mean [standard deviation]) was greater with fentanyl buccal tablet (0.88 [1.20]) vs oxycodone (0.76 [1.13]; P < 0.001). Patients preferred fentanyl buccal tablet (47%) over oxycodone (35%); 18% had no preference. Patients and clinicians reported consistently better functional improvement and satisfaction with fentanyl buccal tablet vs short-acting opioids (P < 0.05).ConclusionsFentanyl buccal tablet was associated with rapid onset of analgesia and improvements in functional status and patient satisfaction compared with immediate-release oxycodone.Wiley Periodicals, Inc.
