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.

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. No significant financial relationships to disclose.

BackgroundAcute anterior uveitis (AAU) is the most common extra-articular manifestation in patients with axial spondyloarthritis (axSpA). C-VIEW investigates the impact of the Fc-free TNF inhibitor certolizumab pegol (CZP) on AAU flares in patients with active axSpA at high risk of recurrent AAU.MethodsC-VIEW (NCT03020992) is a 96-week ongoing, multicentre, open-label, phase 4 study. Included patients had an axSpA diagnosis, a history of recurrent AAU (≥2 AAU flares, ≥1 flare in the year prior to study entry), HLA-B27 positivity, active disease, and failure of ≥2 non-steroidal anti-inflammatory drugs. Patients received CZP 400 mg at Weeks 0/2/4, then 200 mg every 2 weeks up to 96 weeks. This 48-week pre-planned interim analysis compares AAU flare incidence in the 48 weeks before and after initiation of CZP treatment, using Poisson regression to account for possible within-patient correlations.ResultsIn total, 89 patients were included (male: 63%; radiographic/non-radiographic axSpA: 85%/15%; mean axSpA disease duration: 8.6 years). During 48 weeks’ CZP treatment, 13 (15%) patients experienced 15 AAU flares, representing an 87% reduction in AAU incidence rate (146.6 per 100 patient-years (PY) in the 48 weeks pre-baseline to 18.7 per 100 PY during CZP treatment). Poisson regression analysis showed that the incidence rate of AAU per patient reduced from 1.5 to 0.2 (p<0.001). No new safety signals were identified.ConclusionsThere was a significant reduction in the AAU flare rate during 48 weeks of CZP treatment, indicating that CZP is a suitable treatment option for patients with active axSpA and a history of recurrent AAU.
