SUBLOCADE, Indivior's monthly injectable formulation of buprenorphine for the treatment of moderate to severe opioid use disorder (OUD), is the foundation of Indivior's portfolio of innovative treatments aimed at transforming how the chronic condition of OUD is managed. This PAS seeks to further expand treatment options via two proposed updates to the SUBLOCADE label, including:

Indivior's PAS included comprehensive data which we believe demonstrate the efficacy and safety of the new rapid induction protocol and SUBLOCADE's pharmacokinetic profile following injection at alternative sites. These updates are expected to enhance the patient experience and expand treatment access especially for those patients who, similar to the study participants, have long-term opioid use including fentanyl. A Priority Review designation means that the FDA's goal is to take action on an application within 6 months (compared to 10 months under standard review) and, if approved, would translate into significant improvements in OUD treatment with SUBLOCADE.

INDICATION AND HIGHLIGHTED SAFETY INFORMATION
INDICATION
SUBLOCADE is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a buprenorphine-containing product, followed by dose adjustment for a minimum of 7 days.
SUBLOCADE should be used as part of a complete treatment plan that includes counseling and psychosocial support.
HIGHLIGHTED SAFETY INFORMATION
WARNING: RISK OF SERIOUS HARM OR DEATH WITH INTRAVENOUS ADMINISTRATION; SUBLOCADE RISK EVALUATION AND MITIGATION STRATEGY
CONTRAINDICATIONS
SUBLOCADE should not be administered to patients who have been shown to be hypersensitive to buprenorphine or any component of Indivior's proprietary buprenorphine gel depot delivery system.
WARNINGS AND PRECAUTIONS
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.
Opioids can cause sleep-related breathing disorders e.g., central sleep apnea (CSA), sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. Consider decreasing the opioid using best practices for opioid taper if CSA occurs.
Strongly consider prescribing naloxone at SUBLOCADE initiation or renewal because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. Educate patients and caregivers on how to recognize respiratory depression and how to treat with naloxone if prescribed.
Risk of Serious Injection Site Reactions: The most common injection site reactions are pain, erythema and pruritus with some involving abscess, ulceration, and necrosis. The likelihood of serious injection site reactions may increase with inadvertent intramuscular or intradermal administration.
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 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
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.
