pSivida Corp. Announces ILUVIEN(R) Receives Marketing Authorization in Austria for the Treatment of Chronic Diabetic Macular Edema

WATERTOWN, Mass., Apr 24, 2012 -- pSivida Corp, a leader in developing sustained release, drug delivery products for treatment of back-of-the-eye diseases, today announced the Austrian Agency for Health and Food Safety (Osterreichische Agentur fur Gesundheit und Ernahrungssicherheit, AGES) has granted marketing authorization to ILUVIEN(R) for the treatment of vision impairment associated with chronic diabetic macular edema (DME) considered insufficiently responsive to available therapies.

This marketing authorization follows the completion of the Decentralized Regulatory Procedure (DCP), in which the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom, serving as the Reference Member State, delivered a positive outcome for ILUVIEN along with six Concerned Members States (CMS), which include Austria, France, Germany, Italy, Spain and Portugal. The Austrian authorization is the first national approval in the EU. Additional CMS marketing authorizations are expected in the coming months and Alimera has reported it continues to expect ILUVIEN to be available in the EU by the end of 2012.

"We are very pleased ILUVIEN has received this marketing authorization and will soon be available to patients in Austria," said Dr. Paul Ashton, president and chief executive officer of pSivida . We look forward to ILUVIEN receiving the additional expected EU approvals."

The International Diabetes Federation estimates that approximately 750,000 people are currently living with diabetes in Austria, and Alimera estimates more than 40,000 people suffer from DME.

ILUVIEN is an injectable, sustained-release intravitreal insert that releases sub-microgram levels of fluocinolone acetonide (FAc) for up to 36 months for the treatment of chronic DME. pSivida is developing an insert of the same design for the treatment of uveitis affecting the posterior of the eye.
