News Release

BioDelivery Sciences Announces Presentation of Data on the Impact of a State Formulary Conversion to BUNAVAIL® at the International Conference on Opioids

July 6, 2016 at 12:00 AM EDT

RALEIGH, N.C., June 6, 2016 /PRNewswire/ -- BioDelivery Sciences International, Inc. (NASDAQ: BDSI) announced the presentation of data today at the 5th International Conference on Opioids (ICOO 2016), which takes place June 5-7, 2016 in Boston, Massachusetts.  The poster is being presented by Dr. Richard Soper, Chief, Addiction Medicine & Chair, Board of Directors, Center for Behavioral Wellness, Nashville, Tennessee, who is lead author.

The abstract, titled Reduced Buprenorphine/Naloxone Prescriptions Dispensed in a State Medicaid Population Following Formulary Conversion from Suboxone to Bunavail: Implications for Potential Diversion, analyzed prescription patterns preceding and following a complete switch of prescriptions covered by Medicaid in the State of Tennessee on October 1, 2015 from Suboxone® sublingual film to BUNAVAIL® buccal film.  This switched occurred following the implementation of a formulary change making BUNAVAIL the exclusive, preferred buprenorphine treatment for opioid dependence in this major fee-for-service state Medicaid plan.

Results showed prescriptions of Suboxone decreased from a weekly consistent peak of more than 1,600 to less than 100 within one month of the switch, while BUNAVAIL prescriptions increased from a low of 19 to approximately 600. This approximate 63 percent reduction in overall prescriptions in the plan remained throughout the measurement period, which may result in a savings of approximately $14 million to the state budget.  This real-world switch with a more than 60 percent reduction in overall buprenorphine prescriptions in the state suggests that a significant amount of prior product use may not have been used for the intended patient (a phenomenon known as diversion) or for its intended purpose (i.e., for the maintenance treatment of opioid dependence) as opposed to misuse or abuse of the product.

Dr. Soper stated "Medication-assisted therapy is an important part of helping patients manage and overcome opioid addiction, yet it needs to be done responsibly. The data presented suggests that the BUNAVAIL formulation of buprenorphine and naloxone, when made available, has a meaningful impact on overall usage and may be discouraging those who otherwise might not have been using the medication in a responsible manner. Prescribers should consider the potential for diversion when prescribing a treatment and should make every effort to minimize it."

Dr. Mark A. Sirgo, President and Chief Exec of BioDelivery Sciences said, "BUNAVAIL, with its buccal administration, has been shown to be capable of delivering the same amount of buprenorphine with only half of the dose delivered with other formulations. In addition, when these doctors were surveyed, over 60% indicated that they believe BUNAVAIL is more difficult to abuse based on the BEMA technology.  Overall this information, in totality, leads us to believe that our unique and proprietary BEMA drug delivery technology, incorporated into BUNAVAIL, could make it less attractive for those who may be otherwise inclined to potentially misuse, abuse, or divert their treatment.  We look forward to continuing our ongoing efforts to work effectively with providers and payers in additional states and regions around the country, and believe that our experience with BUNAVAIL in Tennessee is a model we can apply in other states." 

The International Conference on Opioids is presented by the Journal of Opioid Management.  The program is led by renowned specialists and is designed to inform primary care physicians, pain specialists, pharmacists and others with an interest in opioids and the public health, with data and information on best practices, abuses and legal ramifications of opioids.
