Camurus announced today that the Australian Therapeutic Goods Administration (TGA) has approved the company's lead products Buvidal® Weekly and Buvidal® Monthly (CAM2038) for maintenance treatment of opioid dependence within a framework of medical, social and psychosocial support.
"Opioid dependence and non-medical opioid use are large and growing issues in Australia with significant negative impact on individuals, their families and the wider community," said Fredrik Tiberg, President and CEO of Camurus. "Today's approval of Buvidal Weekly and Buvidal Monthly will for the first time give Australian patients access to a long-acting buprenorphine treatment for opioid dependence with a meaningful clinical benefit recognized by the TGA.
Formulated with Camurus' proprietary FluidCrystal® injection depot technology, Buvidal is a lipid-based solution which, once injected, transforms into a nanostructured gel-like depot. The depot slowly biodegrades over time, releasing buprenorphine which blocks the drug-liking effect of opioids in the brain and reduces withdrawal, craving and patient's use of illicit opioids. [1-4]
"The introduction of Buvidal represents the most significant development in over 15 years of opioid dependence treatment in Australia. The flexibility of weekly and monthly injection depots will make treatment much more convenient for patients, reducing the costs and inconvenience of daily dosing, and should serve to lessen the stigma experienced by many patients," said Professor Nicholas Lintzeris, Director of Drug & Alcohol Services, South East Sydney Local Health District and the Division of Addiction Medicine, Central Clinical School, University of Sydney.

The TGA approval of Buvidal Weekly and Buvidal Monthly is based on safety and efficacy data from a global development program comprising seven clinical studies, including a randomized, double-blind, double-dummy, active controlled Phase 3 study in 428 patients with opioid dependence. Results from this study demonstrated improved treatment outcomes with Buvidal compared to daily standard treatment with sublingual buprenorphine/naloxone. [4]
The Australian approval follows the recent European Commission approval of Buvidal®, announced 22 November 2018. In the US, the Food and Drug Administration has issued a PDUFA goal date of 26 December 2018 for CAM2038 to Camurus' US partner Braeburn.
About opioid dependence
Opioid dependence is an escalating global health problem, contributing to significant mental, physical and social adverse consequences that include transmission of infectious diseases, criminal activity and incarceration, and unintentional overdose and death. [6]
Opioid use is a serious public health issue in Australia with an estimated 460,000 people aged over 14 years having used opioids - including morphine, oxycodone, methadone and heroin - for non-medical purposes at some time.
