The Impact

Objective: To evaluate the effect of fentanyl buccal tablet (FBT) on pain-related anxiety in opioid-tolerant patients with chronic pain and breakthrough pain (BTP).Design: This study consisted of a screening visit, open-label titration period, and 4-week open-label treatment period.Setting: Thirty-one US study centers.Patients: Opioid-tolerant adults with chronic, persistent pain experiencing 1-4 BTP episodes per day at baseline. Two hundred eighteen patients were enrolled in this study; 180 completed the titration period; and 169 completed the treatment period.Intervention: Patients were treated with FBT (100-800 g) for BTP episodes for 4 weeks while continuing their around-the-clock opioid regimens.Main outcome measures: Change from baseline in the Pain Anxiety Symptoms Scale (PASS) total score at the final visit.Results: Based on a mean baseline PASS total score of 82.6, study patients had a high level of anxiety; 92 patients (42 percent) had a history of anxiety disorders. The change from baseline in PASS total score was not statistically significant (mean change, −1.6; p = 0.322). Numerical improvements were reported in some secondary measures (eg, Beck Depression Inventory total score [mean change, −1.1; p = 0.038]) and categorical measures (eg, Pain Flare Treatment Satisfaction, Patient Assessment of Function, and Clinician Assessment of Patient Function ratings). FBT was generally well tolerated, with no serious adverse events related to study drug.Conclusions: Four weeks of treatment with FBT did not reduce anxiety to a clinically meaningful extent, although improvement was reported in several secondary measures of functioning. Further research is needed to assess the impact of treatment for BTP on anxiety symptoms in opioid-tolerant patients with BTP.

Study Results

9053 Background: Fentanyl buccal tablet (FBT) is an effervescent formulation of fentanyl indicated for the management of breakthough pain in opioid-tolerant cancer patients. This open-label study investigated the absorption profile, safety, and tolerability of FBT in cancer patients with or without oral mucositis. Methods: Patients self-administered a single 200 μg dose of FBT. Pharmacokinetic assessments, oral mucosal examinations, and measurements of vital signs were performed at intervals of up to 8 hours following FBT placement. Adverse events (AEs) were monitored throughout the study. Results: 16 patients (8 with, 8 without mucositis) received FBT and completed the study. Mucositis was mild (functional/symptomatic grade 1 for 7 patients, grade 2 for 1 patient; clinical grade 1 for all patients). The absorption profile of FBT was similar in patients with and without mucositis. Mean±SD Cmax values were 1.25±0.78 ng/mL and 1.24±0.77 ng/mL in patients with or without mucositis, respectively. Maximum plasma concentrations of fentanyl were achieved rapidly, and were not significantly different in the two groups: median (range) tmax 25.0 (15.0–45.0) min in patients with mucositis, 22.5 (10.0–121.0) min in patients without (p=0.79). FBT was well tolerated; 4 patients experienced =1 treatment-emergent AE. Dizziness (mild) was reported by 1 patient in each group, and resolved. One patient in each group experienced a treatment-related AE (dizziness). There were no deaths, serious AEs, or withdrawals due to AEs. No application site AEs or changes in oral mucosal assessments were reported. Conclusions: The absorption profile of FBT was similar in patients with or without oral mucositis, which suggests that dose adjustment of FBT is not required when mild oral mucositis is present. FBT was generally safe and well tolerated, and not associated with adverse changes in the oral mucosa. Further studies in patients with grade 3–4 mucositis are warranted.

9057 Background: Episodes of cancer-related breakthrough pain (BTP) often peak in intensity in minutes. Pain relief with traditional, short-acting oral opioids is often not achieved for =30 min. Fentanyl buccal tablet (FBT) has a rapid onset of analgesia. This double- blind, randomized, placebo-controlled study evaluated the efficacy and safety of FBT in opioid-tolerant patients with cancer and BTP. Methods: After open-label titration to establish a successful dose of FBT, patients were randomized to prespecified, double-blinded sequences of 10 tablets (7 FBT, 3 placebo). Pain intensity (PI) was assessed from 5 to 120 min post dose. The primary efficacy measure was the sum of PI differences (PIDs) for the first 60 min (SPID60); secondary measures included PIDs, =33% and =50% improvements in PI, and global medication performance (GMP). Use of supplemental BTP medication and adverse events (AEs) were reported. Results: 129 patients were enrolled; 87/125 treated (70%) identified an effective FBT dose and entered the double-blind phase. SPID60 significantly favored FBT vs placebo (mean±SEM, 9.7±0.63 vs 4.9±0.50; p<0.0001). PID differed significantly vs placebo at 10 min (mean±SEM, 0.9±0.09 vs 0.5±0.09; p<0.0001) and at all time points through 2 hr (p<0.0001). Improvements in PI of =33% and =50% from baseline occurred in a larger proportion of episodes following FBT vs placebo from 10 min (16% vs 10% and 7% vs 4%, respectively; p<0.05) through 2 hr (74% vs 38% and 66% vs 28%; p<0.0001). Ratings of GMP were superior for FBT vs placebo at 60 and 120 min (p<0.0001). Supplemental opioids were required for approximately 3 times more BTP episodes following placebo compared with FBT. AEs were typical for opioids, e.g. nausea (13%), dizziness (11%), fatigue (8%), and constipation (6%). Application site-related AEs occurred in 12 patients (10%). A total of 11/125 (9%) patients had =1 serious AE; these were considered not/unlikely to be related to study drug. Conclusions: FBT was effective and well tolerated in the management of BTP in opioid-tolerant patients with cancer-related pain, with an early onset of analgesia and a sustained duration of effect.
