Flamel Technologies : Announces Positive Results From First Clinical Trials With Trigger Lock™ Hydromorphone Abuse-Deterrent Product

Meeting With FDA Will Be Requested Before the End of 2015

The PK studies were intended to provide sufficient data for the Company to select a preferred prototype formulation to move forward into pivotal studies. The studies compared three FT227 prototypes to the comparator product Jurnista© (sold as Exalgo© in the United States) in both fasted and fed conditions at a dose of 32mg.
Under fasted conditions, comparing the area under the curve (AUC) and the peak plasma concentration (Cmax) of FT227 to Jurnista© in 16 subjects, the results identified a FT227 formulation that met the bioequivalence criteria for both parameters. Under fed conditions (14 subjects), the same formulation was bioequivalent in terms of AUC to Jurnista© but outside of the Cmax bioequivalence criterion at the lower confidence interval level. Comparing the effect of food on the PK parameters of the FT227 prototypes across the two studies, no notable difference is seen in either AUC or Cmax in fed and fasted conditions. This suggests that administration of FT227 will not be subject to a clinically relevant food effect.
In both studies FT227 was well tolerated and no serious adverse events were reported.
In addition, Flamel has generated substantial in vitro data comparing the abuse deterrence properties of FT227 compared to other marketed abuse-deterrent opioid products. The Company is confident that Trigger Lock™ is a robust platform for opioids that will set a high standard in terms of abuse deterrence. Further abuse deterrence data are being generated by an independent contract research organization and will be subject to further announcements. Flamel is planning to meet with the U.S. Food and Drug Administration (FDA) before the end of 2015 to discuss the remainder of the development plan for FT227. The product is designed to be filed as a 505(b)(2) New Drug Application (NDA). Based on current

expectations, the selected formulation will be scaled-up over the coming months and the Company plans to begin pivotal registration studies by mid-2016.
"We are very pleased with these initial data on FT227 Trigger Lock™ and we are highly confident in our Trigger Lock™ abuse deterrent platform. We look forward to meeting with the FDA and to moving FT227 into pivotal studies in 2016," said Mike Anderson, Chief Executive Officer.
As of December 2014, Trigger Lock™ is protected by seven Flamel patent application families, which
expire between November 2025 and December 2033
