Ambrilia Biopharma Inc. Prioritizes its Divestment Strategy and Takes Cost-Cutting Actions to Extend Cash; Reduces Headcount By 33%

MONTREAL, QUEBEC--(Marketwire - September 29, 2008) - Ambrilia Biopharma Inc. (TSX: AMB) today announced that it has elected to prioritize its divestment strategy of monetizing (selling or licensing) its clinical assets C2L and goserelin before year-end along with cost-cutting actions which result in a hold on its antiviral R&D activities, significant reduction in cash consumption and a 33% decrease in headcount. Previously announced 2008 milestones for the main development programs are unaffected.

“This was a tough decision but Ambrilia having less than 12-months of cash in a difficult market environment, immediate action was required in order to extend its cash further into 2009 while concentrating only on the monetization of the oncology assets,” said Philippe Calais, President and CEO. “At the moment, we believe the divestment strategy offers the best probability of success for the Company and more importantly, the potential to generate non-dilutive R&D funding and extend the runway to financing. When fully executed, Ambrilia will be in a position to better assess various strategic options for its antivirals portfolio.”

He concluded, “We are moving closer to reaching our strategic goal for octreotide C2L and goserelin which is to conclude an agreement with the best acquirer or licensing partner by the end of 2008.”

Ambrilia’s further commitment to its divestment strategy and cost-cutting actions impact primarily the antiviral R&D activities and the cash burn:

Monthly cash burn: target reduced from less than or equal to $1.4M to less than or equal to $1.0M

The cost-cutting actions include a 33% decrease in headcount, from 43 to 29 employees, in the basic research and preclinical team and administrative support functions. Some outsourcing and consultant expenses related to the hold on virology R&D activities were also cut. These measures are expected to decrease the Company’s monthly cash burn by approximately $0.4M.
