Indivior Announces Health Canada Approval of SUBLOCADE™ (Buprenorphine Extended-Release) Injection for Patients with Moderate to Severe Opioid Use Disorder

SUBLOCADE is the first and only once-monthly injectable buprenorphine formulation approved in
Canada for the management of moderate to severe opioid use disorder

Slough, UK and Richmond, VA, 23 November 2018 – Indivior PLC (LON: INDV) today announced that Health Canada has approved SUBLOCADETM (buprenorphine extended-release) injection for subcutaneous use, for the management of moderate to severe opioid use disorder (OUD) in adult patients who have been inducted and clinically stabilized on a transmucosal buprenorphinecontaining product. SUBLOCADE should be used as part of a complete treatment plan that includes counseling and psychosocial support, and must only be administered once a month, subcutaneously in the abdominal region by a healthcare provider. In Canada, SUBLOCADE will be marketed by Indivior Canada Ltd., and will be available by the second half of 2019.

“We are committed to helping the patients, families and communities impacted by the opioid epidemic around the world,” said Shaun Thaxter, Chief Executive Office of Indivior. “The approval of SUBLOCADE in Canada is an important milestone, and we look forward to continuing to partner with the Canadian treatment community to help those with opioid use disorder.”

Illicit opioid use in Canada is a national public health crisis that continues to grow, with 3,005 and 3,996 apparent opioid-related deaths in 2016 and 2017 respectively. From January to March 2018, there were at least 1,036 apparent opioid-related deaths; of these deaths, 94% were accidental and 73% involved fentanyl or fentanyl analogues. Despite this growing crisis, barriers such as stigma continue to prevent patients from accessing treatment.

SUBLOCADE, in combination with counseling and psychosocial support, is a once-monthly medication-assisted treatment (MAT) that contains buprenorphine, a mu-opioid receptor agonist. It uses the ATRIGEL® Delivery System and solidifies on contact with bodily fluids to deliver buprenorphine over the one month period.

In clinical trials, common adverse reactions (≥5% patients) included constipation, nausea, vomiting, headache, fatigue, insomnia, hepatic enzymes increased, and injection site pain and pruritus. Injection site reactions were reported in 16% of the patients. None of the injection site reactions were serious and one led to study treatment discontinuation. SUBLOCADE has a SERIOUS WARNINGS AND PRECAUTIONS BOX. Serious harm or death could result if administered intravenously.

This approval from Health Canada follows approval of SUBLOCADE by the U.S. Food and Drug Administration (FDA) on November 30, 2017.


In Canada, SUBLOCADE is indicated for the management of moderate to severe opioid use disorder in adult patients who have been inducted and clinically stabilized on a transmucosal buprenorphine- containing product. SUBLOCADE should be used as part of a complete treatment plan that includes counselling and psychosocial support. SUBLOCADE must only be administered subcutaneously in the abdominal region by a healthcare provider.
