New Analysis From One-Year Study of Monthly Buprenorphine Extended-Release Injections Showed Improved or Stable Patient-Centered Outcomes

Sustained improvements in multiple health outcomes following twelve monthly buprenorphine extended-release injections in patients with opioid use disorder.

Findings published in the Journal of Substance Abuse Treatment.

Slough, UK and Richmond, VA, December 2, 2019 – Indivior PLC (LON: INDV) announced today that new analysis from a 12-month investigation of monthly buprenorphine extended-release injections showed that study participants who were treated with SUBLOCADE® (buprenorphine extendedrelease) injection, for subcutaneous use (CIII), demonstrated improved or maintained patientcentered outcomes across the following measures:
• Health status and health-related quality of life,
• Employment/insurance status,
• Healthcare resource utilization,
• Medication satisfaction,
• Treatment effectiveness and improvement in addiction severity as measured by a patient reported Addiction Severity Index.

SUBLOCADE is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a transmucosal buprenorphine-containing product followed by a dose
adjustment period for a minimum of seven days. SUBLOCADE should be used as part of a complete treatment program that includes counseling and psychosocial support.

“This analysis offers new insight into extended-release buprenorphine treatment in patients with opioid use disorder on important measures of patient-centered outcomes that extend beyond
abstinence and treatment retention,“ said the study’s lead author, Walter Ling, MD, Research Professor, Department of Family Medicine, David Geffen School of Medicine, UCLA. "These results
showed that patients experienced improvements in physical and mental health which may help in the recovery journey and positively impact lifestyle, including employment."

The study, entitled, "Effects of monthly buprenorphine extended-release injections on patientcentered outcomes: a long-term study" was published online in the December issue of the Journal of
Substance Abuse Treatment (

By the end of the 12-month study, patient-reported outcomes included:
• 88% of the 206 study participants reported medication satisfaction, 
• Treatment Effectiveness Assessment scores improved, and quality of life scores were stable or improved,
• Employment rate increased by 7% from 44.2% to 51.2 %.1

Health insurance coverage remained stable at approximately 55%. Health care utilization during the 3,604-person-months of the study included 21 hospitalizations, 140 emergency department visits and 923 outpatient services.1 Rates of observed hospilizations, emergency, and outpatient service
visits were much lower than utilization observed in a claims analysis focusing on participants receiving buprenorphine medication-assisted treatment.3 Confidence intervals did not cross zero for all comparisons.

“These 12-month findings strengthen our original observations that previously showed that participants receiving SUBLOCADE® over a 6-month period reported better health, higher
medication satisfaction, increased employment, and decreased healthcare utilization compared to placebo,” said Christian Heidbreder, PhD, Indivior’s Chief Scientific Officer. “These findings also show
that patient-centered outcomes that can be measured during office visits may help clinicians assess their patient’s improvement.”

Medication-assisted treatment (MAT) combines medication and counseling to treat both the physical and behavioral parts of opioid addiction, with the goal of helping people achieve and
maintain recovery.4,5 The combination of medicine and psychosocial therapy have been proven successful in treating OUD and can help extend recovery. In fact, MAT has been shown to be more effective than either medication or counseling alone.5

About the Study
This study was a multi-center, open-label, long-term clinical safety study (NCT02510014) evaluating up to 12 months of buprenorphine extended-release injection therapy in people 18 to 65 years of
age who were seeking treatment for moderate or severe OUD as defined in the Diagnostic Statistical Manual 5 (DSM-5) (American Psychiatric Association, 2013). The study included patients who
completed the randomized, double-blind, placebo-controlled study (NCT02357901, RB-US-13-0001) and patients that did not participate in study RB-US-13-0001. This analysis focused on patients who
did not participate in study RB-US-13-0001. The data reported are for patient-centered outcome
measures which were a tertiary outcome of the study.

Following a 7-day screening period, these subjects received treatment with a 3- to 14-day run-in period with sublingual buprenorphine/naloxone, titrated to a maximum dose of 24 mg daily based
on clinical response and physician judgement; followed by up to 12 monthly injections of SUBLOCADE.

All participants received an initial 300 mg subcutaneous injection. For subsequent doses, the SUBLOCADE dose could be reduced to 100 mg and then increased back to 300 mg, based on the
medical judgment of the investigator. All participants received injections of SUBLOCADE separated by 28 (-2/+ 4) days. A 4-week follow-up period was used to assess any further safety signals after the
last dose. Patient-centered outcome measures including health related quality of life measures (E5- QD-5L Index, EQ5D-5L VAS, SF-36v2), Treatment Effectiveness Assessment, Addiction Severity Index-
Lite, and Medication Satisfaction Questionnaire were performed periodically and longitudinally throughout the study.

SUBLOCADE (buprenorphine extended-release) injection, for subcutaneous use (CIII) is a prescription medicine used to treat adults with moderate to severe addiction (dependence) to opioid drugs
(prescription or illegal) who have received an oral transmucosal (used under the tongue or inside the cheek) buprenorphine-containing medicine at a dose that controls withdrawal symptoms for at least 7 days. SUBLOCADE is part of a complete treatment plan that should include counseling.2
The overall safety profile for SUBLOCADE, given by a healthcare provider in clinical trials, was consistent with the known safety profile of transmucosal buprenorphine, except for injection site reactions.2 Adverse reactions commonly associated with SUBLOCADE (in ≥5% of subjects) were constipation, headache, nausea, injection site pruritus, vomiting, increased hepatic enzymes, fatigue and injection site pain. Injection site reactions were reported in 16.5% of patients in Phase 3
studies.2 Most of the injection site adverse reactions (ADRs) were of mild to moderate severity.2 None of the injection site reactions were serious, and one led to study treatment discontinuation.2 SUBLOCADE has a BOXED WARNING and is available through restricted distribution under the SUBLOCADE Risk Evaluation and Mitigation Strategy (REMS) Program.2 Pursuant to the SUBLOCADE
REMS, all healthcare settings and pharmacies that order and dispense SUBLOCADE must be certified and establish processes and procedures to verify the medication is dispensed directly to a healthcare
provider for administration by a healthcare provider and is not dispensed directly to the patient.2 Moreover, certified healthcare settings and pharmacies must not distribute, transfer, loan or sell SUBLOCADE.

SUBLOCADE is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a transmucosal buprenorphine-containing product followed by a dose adjustment period for a minimum of seven days.

SUBLOCADE should be used as part of a complete treatment program that includes counseling and psychosocial support.

Prescription use of this product is limited under the Drug Addiction Treatment Act.


• Serious harm or death could result if administered intravenously. SUBLOCADE forms a solid mass upon contact with body fluids and may cause occlusion, local tissue damage, and thrombo-embolic events, including life threatening pulmonary emboli, if administered intravenously.
• Because of the risk of serious harm or death that could result from intravenous selfadministration, SUBLOCADE is only available through a restricted program called the SUBLOCADE REMS Program. Healthcare settings and pharmacies that order and dispense SUBLOCADE must be certified in this program and comply with the REMS requirements.

SUBLOCADE should not be administered to patients who have been shown to be hypersensitive to buprenorphine or any component of the ATRIGEL® delivery system.

Addiction, Abuse, and Misuse: SUBLOCADE contains buprenorphine, a Schedule III controlled substance that can be abused in a manner similar to other opioids. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors.

Respiratory Depression: Life threatening respiratory depression and death have occurred in association with buprenorphine. Warn patients of the potential danger of self-administration of benzodiazepines or other CNS depressants while under treatment with SUBLOCADE.

Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome is an expected and treatable outcome of prolonged use of opioids during pregnancy.

Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid.

Risk of Opioid Withdrawal with Abrupt Discontinuation: If treatment with SUBLOCADE is discontinued, monitor patients for several months for withdrawal and treat appropriately.

Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to and during treatment.

Risk of Withdrawal in Patients Dependent on Full Agonist Opioids: Verify that patient is clinically stable on transmucosal buprenorphine before injecting SUBLOCADE.

Treatment of Emergent Acute Pain: Treat pain with a non-opioid analgesic whenever possible. If opioid therapy is required, monitor patients closely because higher doses may be required for analgesic effect.

Adverse reactions commonly associated with SUBLOCADE (in ≥5% of subjects) were constipation, headache, nausea, injection site pruritus, vomiting, increased hepatic enzymes, fatigue, and injection site pain.

About Opioid Use Disorder (OUD)
Opioid addiction isn’t a moral weakness. Opioid addiction is a chronic disease called Opioid Use Disorder (OUD) in which people develop a pattern of using opioids that can lead to negative consequences. Opioid addiction may affect the parts of the brain that control impulses, judgment, and decision-making. Patients become trapped in a cycle of opioid use, which produces changes in brain function that can reduce their ability to control their use.

In 2018, an estimated 10.3 million people aged 12 or older misused opioids in the past year, including 9.9 million prescription pain reliever misusers and 808,000 heroin users. Approximately 506,000 people misused prescription pain relievers and used heroin in the past year. SUBLOCADE is not indicated for use in children younger than 18 years of age. Buprenorphine, the active ingredient of SUBLOCADE can cause severe, possibly fatal, respiratory depression in children who are accidentally exposed to it.
