Economic burden and dosing trends of buprenorphine buccal film and transdermal patch in chronic low back pain.

Aim: Exploring prescribing trends and economic burden of chronic low back pain (cLBP) patients prescribed buprenorphine buccal film (Belbuca®) or transdermal patches. Methods: In the MarketScan® commercial insurance claims (employees and their spouses/dependents, 2018-2021), the first film or patch prescription date was an index event. The observation covered 6-month pre-index and 12-month post-index periods. Results: Patients were propensity-score matched (708 per cohort). Buprenorphine initiation had stable cost trends in buccal film and increasing trends in transdermal patch cohort. Between-cohort comparisons of healthcare expenditures, cost trends and resource utilization showed significant differences, mostly in favor of buccal film. Buccal film also had higher daily doses and wider dosing range. Conclusion: Buprenorphine film is more cost-effective cLBP treatment with more flexible dosing.

What is this article about? This retrospective study included patients with chronic low back pain (cLBP) and commercial insurance in the USA. Only patients treated with Belbuca®, a buprenorphine buccal film, or a buprenorphine transdermal patch were included. Patients were observed 6 months prior to and 12 months after the first buprenorphine prescription. Healthcare costs, cost trends, resource use and buprenorphine treatment characteristics were explored.What were the results? Patients with cLBP on buccal film had lower costs, stable cost trends and less healthcare resources used. Also, they had higher buprenorphine daily doses.What do the results mean? The results imply that buccal film is less costly for cLBP patients than patches. The buccal film had more flexible dosing with higher daily doses, which might be associated with better pain control.

Serious treatment-emergent adverse events in chronic low back pain patients treated with buprenorphine or oral opioids: a retrospective commercial claims analysis.

Aim: Explore the safety of Belbuca® (buprenorphine buccal film), buprenorphine transdermal patches and oral opioids for chronic low back pain (cLBP) treatment. Methods: The retrospective analysis of the MarketScan Commercial database (2018-2021) included treatment-naive cLBP adults. The first date of buprenorphine (Belbuca and transdermal patch) or opioid prescription was index date. Cohorts were defined based on the index medication. Observation included a 6-month pre-index period, while post-index lasted until the end of continuous insurance coverage. There were 44 relevant treatment-emergent adverse events (TEAEs) identified in the literature. Incidence rate ratio (IRR) and incidence rate difference (IRD) were used to compare serious TEAE rates (in 1000 person-years) between cohorts. Propensity-score matching minimized the selection bias. Results: Buprenorphine had lower rates of 15 serious TEAEs than oral opioids (all p ≤ 0.037), while higher rates only for serious dizziness (IRR 2.44, p = 0.011; driven by Belbuca), opioid abuse/dependence (IRR 3.13, p = 0.004; driven by patches) and cholecystitis (IRD 20.25, p = 0.044; an outlier). Additionally, a comparison between Belbuca and oral opioids showed lower rates of 13 serious TEAEs (all p ≤ 0.024) and a higher serious dizziness rate (IRR 3.17, p = 0.024). Although the rates of serious opioid abuse/dependence were similar (24.60 vs 26.93, p = 0.921), all Belbuca patients and none of the opioid patients had a positive history of these events. Belbuca also had lower rates of five serious TEAEs than transdermal patches (all p ≤ 0.018), including a serious opioid abuse/dependence (IRR 0.04, p < 0.001), but higher rates of serious cholecystitis (IRD 52.17, p = 0.035; an outlier) and suicidal ideation (IRD 156.50, p < 0.001; an outlier). Conclusion: Buprenorphine had a better safety profile than oral opioids in cLBP treatment. Belbuca showed a more favorable TEAE profile than buprenorphine transdermal patches and oral opioids.

Treatment characteristics of chronic low back pain patients treated with buprenorphine buccal film or transdermal patch.

Aims: Retrospective insurance claims analysis exploring treatment characteristics in chronic low back pain patients prescribed buprenorphine buccal film (Belbuca®) or transdermal patches. Patients and methods: The first buprenorphine prescription (buccal film or transdermal patch) was an index event. Patients were observed over 6 month pre- and post-index periods. Propensity score matching minimized the selection bias. Results: Buccal film patients had a higher buprenorphine daily dose (501.7 vs 270.9 µg; p < 0.001). The patch-to-film switching rate was higher than vice versa (11.5 vs 3.8%; p < 0.001). The buccal film showed a greater reduction in opioid prescriptions (-1.1 vs -0.7; p = 0.012), daily morphine milligram equivalents (-12.6 vs -7.3; p < 0.001) and opioid treatment duration (-13.4 vs -7.6 days; p = 0.022). Conclusion: Buccal film was associated with higher buprenorphine doses and a greater reduction of opioid burden.

What is this article about? The analysis explored treatment patterns in chronic low back pain patients treated with different buprenorphine drugs. The use of other pain medications was also evaluated. Buprenorphine buccal film (Belbuca^®) was compared with transdermal patches. This study used commercial insurance data of US patients. What were the results? The most relevant findings were: Patients using buccal film had about two-times higher buprenorphine daily doses. About 12% of patch patients switched to film, while approximately 4% of film patients switched to patch. Initiation of both buprenorphine drugs led to reduced usage of opioids and other pain drugs. Despite a shorter buprenorphine treatment, the film was associated with a greater reduction in opioid use than the patch. What do the results of the study mean? The results showed that patients prescribed buprenorphine buccal film would be able to achieve higher daily doses required for appropriate chronic low back pain management. The buccal film will also lead to a great reduction in concomitant opioid use. These advantages may explain why more patients switched from buprenorphine transdermal patch to buccal film than the other way around.
