Braeburn Pharmaceuticals and Camurus announce the presentation of new data from clinical studies of long-acting buprenorphine

21 October 2016

Princeton, New Jersey and Lund, Sweden — 21 October 2016 — Braeburn Pharmaceuticals and Camurus (NASDAQ STO: CAMX) announce the presentation of new data from three clinical studies on CAM2038, an investigational long-acting injectable medication with flexible dosing, at a joint annual meeting of the International Society of Addiction Medicine (ISAM) and the Canadian Society of Addiction Medicine (CSAM), October 20-22, Montreal, Canada.  ISAM and CSAM are professional societies representing global clinicians and associated professionals in addiction medicine.  The data will be presented this afternoon in a symposia focused on the advances in pharmacology.

The three scientific presentations include:

  • Positive data from a recently completed opioid challenge study, presented by the principal investigator Professor Sharon Walsh, MD/PhD, University of Kentucky.
  • Formulation and pharmacokinetic data for weekly and monthly CAM2038 versus daily sublingual buprenorphine, presented by Professor Fredrik Tiberg, PhD, CEO of Camurus
  • Design and details of the ongoing Phase 3 study were presented by Assoc. Professor Michelle Lofwall, MD/PhD, Medical Director of UK College of Medicine Straus Clinic, University of Kentucky.

Abstracts will be available at the ISAM web site ( after the conference.

About the Opioid Challenge Study
The Opioid Challenge Study was a three-center, randomized, double-blind, inpatient study to evaluate the degree of subjective opioid blocking efficacy of CAM2038 once weekly injection in non-treatment-seeking participants with moderate-to-severe opioid use disorder. After screening, participants were randomized to different CAM2038  once-weekly injections for two weeks. During this period, four challenge sessions were conducted with a randomized hydromorphone dose to determine subjective 'liking' score based on a visual analogue scale. Additional information on the design of the study can be found at

About the Pharmacokinetics Study
The Pharmacokinetics Study was an open-label study designed to evaluate the pharmacokinetics (PK) and safety of buprenorphine and norbuprenorphine following the administration of CAM2038 once weekly or once monthly versus the active control (intravenous (IV) buprenorphine or sublingual buprenorphine (SL)).  There were a total of five different doses that were assessed in the study, the PK profile of all of these doses support the efficacy of both weekly and monthly injections.  The dose-proportional PK also will allow for the individualization of therapy across all stages of buprenorphine therapy. 

About the Phase 3 Study
The primary objective of this double blind double dummy Phase 3 study was designed to demonstrate the safety and efficacy of CAM2038 once weekly and once monthly as compared to the sublingual buprenorphine in treating opioid use disorder. Patients currently seeking treatment were randomized to receive either CAM2038 or placebo and were treated across a 24-week period from initiation into the maintenance phase of treatment.
