Swissmedic approves Buvidal for the treatment of opioid dependence

18 December 2020

Lund, Sweden — 18 December 2020 — Camurus AB (NASDAQ STO: CAMX) announced today that the Swiss agency for therapeutic products, Swissmedic, has approved weekly and monthly Buvidal® prolonged release buprenorphine for the treatment of opioid dependence in adults and adolescents from 16 years of age. This marks the first approval of a long-acting treatment for opioid dependence in Switzerland.

“We are pleased with the expeditious review and approval of our market authorization application for Buvidal by Swissmedic and that patients with opioid dependence in Switzerland will now have access to an effective long-acting treatment,” says Fredrik Tiberg, PhD, President & CEO of Camurus.

There are currently an estimated 20,000 patients receiving pharmacological treatment for opioid dependence in Switzerland, of which a majority are on daily opioid agonist treatment.1

Buvidal is a long-acting buprenorphine medication given as a subcutaneous injection once a week or once a month. In clinical studies, the treatment has proven to be effective in reducing illicit opioid use, alleviating opioid withdrawal and cravings, achieving opioid blockade, and improving patient reported experiences and outcomes compared with daily sublingual medications.2-5

Opioid dependence is a serious, chronic, relapsing disease associated with a disproportionate amount of drug-related harm that includes infectious diseases and other health problems, mortality, unemployment, homelessness and social exclusion6.
