New Data Demonstrate Safety Of Long-Term, Around-The-Clock Treatment With BELBUCA™ (Buprenorphine) Buccal Film For Chronic Pain
Findings also show sustained pain relief with BELBUCA™ treatment for up to 48 weeks among
chronic pain sufferers who require around-the-clock pain relief
BELBUCA™ is the first and only buprenorphine formulation developed with a dissolving film that is absorbed through the inner lining of the cheek for chronic pain management. In the Phase 3, open-label study, many patients receiving treatment with BELBUCA™ twice daily reported a low incidence of typical opioid-like side effects such as nausea and vomiting during treatment titration and for up to 48 weeks of daily therapy. The study also found that BELBUCA™ was effective during long-term treatment and provided sustained pain relief throughout the treatment phase (48 weeks) as measured on the numeric rating scale (NRS).
"Many patients living with chronic pain require long-term treatment to control their suffering, so it is important that patients have options to manage their pain," said
The Phase 3, open-label study enrolled 506 patients with moderate to severe chronic pain, requiring continuous around-the-clock opioid treatment who underwent a dose titration period of up to six weeks followed by a long-term treatment phase (48 weeks). Among these patients, 435 patients went on to receive long-term treatment (<48 weeks) with BELBUCA™ 300 µg (n=52), 450 µg (n=45), 600 µg (n=141), 750 µg (n=62) or 900 µg (n=135) administered every 12 hours. The primary endpoint was to determine the long-term safety and tolerability of BELBUCA™ (dosed every 12 hours); the secondary endpoint was to determine the long-term efficacy of BELBUCA™ (dosed every 12 hours).
In the safety analysis, adverse events (AEs) (> 3%) occurred in 43.1% and 54.0% of patients during the titration (n=506) and long-term treatment (n=435) phases, respectively. The most common AEs included nausea (10.3%), constipation (5.9%) and headache (3.6%) during the titration phase, and nausea (8.3%), vomiting (5.1%) and upper respiratory tract infection (4.8%) during long-term treatment.
For the efficacy endpoint, the average daily pain intensity score during the treatment phase was between 2.9 and 3.1 on a scale of 0 (no pain) to 10 (worst pain imaginable). In addition, the need for rescue medication to relieve breakthrough pain decreased from an average of 3 tablets in the titration to 1.1 tablets in the long-term treatment phase.
"BELBUCA™ is the first and only buprenorphine buccal film combining the established safety and proven efficacy profile of buprenorphine with a novel buccal film delivery system that adds convenience and flexibility of dosing options and presents a unique approach for chronic pain management," said

BELBUCA™ (buprenorphine) buccal film is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.
Limitations of Use
- Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with long-acting opioid formulations, reserve BELBUCA™ for use in patients for whom alternative treatment options (eg, non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
- BELBUCA™ is not indicated as an as-needed (prn) analgesic.
IMPORTANT SAFETY INFORMATION about BELBUCA™
WARNING: ADDICTION, ABUSE, and MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL EXPOSURE; and NEONATAL OPIOID WITHDRAWAL SYNDROME
Addiction, Abuse, and Misuse
BELBUCA™ exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing BELBUCA™, and monitor patients regularly for the development of these behaviors or conditions.
Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with use of BELBUCA™. Monitor for respiratory depression, especially during initiation of BELBUCA™ or following a dose increase. Misuse or abuse of BELBUCA™ by chewing, swallowing, snorting, or injecting buprenorphine extracted from the buccal film will result in the uncontrolled delivery of buprenorphine and pose a significant risk of overdose and death.
Accidental exposure to even one dose of BELBUCA™, especially by children, can result in a fatal overdose of buprenorphine.
Neonatal Opioid Withdrawal Syndrome
Prolonged use of BELBUCA™ during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.
BELBUCA™ is contraindicated in patients with:
- Significant respiratory depression
- Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment
- Known or suspected gastrointestinal obstruction, including paralytic ileus
- Hypersensitivity (eg, anaphylaxis) to buprenorphine
WARNINGS AND PRECAUTIONS
Addiction, Abuse, and Misuse
- BELBUCA™ contains buprenorphine, a Schedule III controlled substance. As an opioid, BELBUCA™ exposes users to the risks of addiction, abuse, and misuse.
- Assess each patient's risk for opioid addiction, abuse, or misuse prior to prescribing BELBUCA™, and monitor all patients receiving BELBUCA™ for the development of these behaviors or conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (eg, major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed BELBUCA™, but use in such patients necessitates intensive counseling about the risks and proper use of BELBUCA™, along with intensive monitoring for signs of addiction, abuse, or misuse.
- Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed BELBUCA™ and in those who obtain the drug illicitly. Addiction can occur at recommended doses and if the drug is misused or abused.
- Abuse or misuse of BELBUCA™ by swallowing may cause choking, overdose, and death.
- Opioid agonists such as BELBUCA™ are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Strategies to reduce the risk include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug.
- Contact a local state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product.
Life-Threatening Respiratory Depression
- Serious, life-threatening, or fatal respiratory depression has been reported with the use of buprenorphine, even when used as recommended. Respiratory depression, from opioid use, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient's clinical status.
- While serious, life-threatening or fatal respiratory depression can occur at any time during the use of BELBUCA™, the risk is greatest during initiation of therapy or following a dose increase. Closely monitor patients for respiratory depression when initiating therapy with BELBUCA™ and following dose increases.
- To reduce the risk of respiratory depression, proper dosing and titration of BELBUCA™ are essential. Overestimating the dose of BELBUCA™ when converting patients from another opioid product may result in fatal overdose with the first dose.
- Accidental exposure to BELBUCA™, especially in children, can result in respiratory depression and death due to an overdose of buprenorphine.
- The most common adverse reactions (>5%) reported by patients treated with BELBUCA™ in the clinical trials were nausea, constipation, headache, vomiting, fatigue, dizziness, somnolence, diarrhea, dry mouth, and upper respiratory tract infection.
