Flamel Technologies (NASDAQ: FLML) today announced that it has exercised its right to regain control of two drugs that use its Trigger Lock™ delivery technology that were formerly being developed in partnership with an undisclosed partner. Trigger Lock is Flamel's proprietary abuse resistant technology for long acting opioid analgesics. Trigger Lock products are designed to be resistant to abuse by extraction, crushing and snorting, as well as resistant to alcohol-induced dose dumping.

"We are delighted that we have obtained the rights back to these two molecules using our Trigger Lock drug delivery technology. Under our control, Flamel will be able to advance development of these products internally or with a new partner," said Mike Anderson, Chief Executive Officer of Flamel.

Flamel intends to provide additional information on the development progress of each of these products once the company has completed an internal review of the data.
