Braeburn Pharmaceuticals and Camurus announce Enrollment goals reached in two pivotal Phase 3 Trials of CAM2038 for treatment of opioid dependence

05 April 2016 | Regulatory

Princeton, New Jersey and Lund, Sweden — 5 April 2016 — Braeburn Pharmaceuticals and Camurus today announce that the enrollment goals for both the 24-week efficacy study and the 48-week safety study were met on 31 March. These two pivotal Phase 3 trials of long-acting subcutaneous buprenorphine injections, CAM2038, in patients with opioid dependence were designed to establish clinical efficacy and long-term safety of both weekly (q1w) and monthly (q4w) formulations.

"Patients with the chronic disease of opioid addiction and the physicians who treat them deserve the most innovative options, just like those suffering from other diseases such as cancer and diabetes," said Behshad Sheldon, President and CEO of Braeburn Pharmaceuticals. “Our success in enrolling over 600 patients in these Phase 3 trials in just three months speaks to the unmet need in this underserved patient population."

The Phase 3 registration program has been designed to utilize both CAM2038 weekly and CAM2038 monthly injectable buprenorphine.  This suite of products will provide physicians with a new way to treat opioid dependence by offering multiple dosing options based on patients needs.  The 24-week efficacy trial is focused on patients that are new to treatment and moving in to maintenance.  The 48-week safety study includes patients that are new entrants to treatment and patients currently receiving maintenance treatment with sublingual buprenorphine.  This will provide valuable data on long-term safety of CAM2038 and the flexibility of weekly and monthly dosing in an open label study. 

“The very rapid enrollment of these studies shows the interest from patients and physicians globally in cutting-edge therapies, like CAM2038, for treating addiction. It also demonstrates the strength of our collaboration and partnership with Braeburn” said Fredrik Tiberg, President and CEO of Camurus. “The Phase III program, being conducted across the Unites States, Australia and five European countries, has been designed to meet the registration requirements of multiple regulatory authorities.”

 “It is exciting to be a part of the clinical program for these new long-acting formulations of buprenorphine.” said Dr. Michelle Lofwall, M.D., University of Kentucky. “There have been very few innovations in the field during the last two decades. CAM2038 will offer a new and different approach to the treatment of opioid dependence.”
