Enrollment Complete In Pivotal Phase 3 Trial Of Medidur(TM) FA For Diabetic Macular Edema

Alimera Sciences Inc., a privately held
ophthalmic pharmaceutical company, and pSivida Limited (Nasdaq: PSDV; ASX:
PSD; Xetra: PSI), announced that enrollment is complete for the
FAME(TM) (Fluocinolone Acetonide in Diabetic Macular Edema) Study of
Medidur(TM) FA for the treatment of Diabetic Macular Edema. FAME is a
double masked, randomized, multi-center study that is following over 900
patients in the U.S., Canada, Europe and India for 36 months with safety
and efficacy assessed at two years. Alimera Sciences and pSivida are
jointly developing Medidur FA under a collaborative research and
development agreement.

“Alimera Sciences is very excited to have completed enrollment in the
FAME Study as this brings us closer to taking Medidur FA, the next
generation of retinal drug delivery, to market and to our ultimate goal of
delivering treatments that enrich patients’ quality of life,” said Alimera
CEO Dan Myers.

Medidur, a tiny, injectable insert, is being studied as a way to
deliver fluocinolone acetonide, a corticosteroid, to the retina for up to
three years as a treatment for diabetic macular edema (DME). Using a
proprietary 25 gauge injector system, an eye care professional injects the
Medidur insert into the vitreous through a minimally invasive procedure in
an outpatient setting.

“This marks an important milestone for the company in our profit
sharing collaboration with Alimera. We are very pleased at the continued
development of Medidur FA, based on our technologies that have already been
approved for two back of the eye diseases. We are optimistic that Medidur
FA will offer a solution to the large market we see for this product,” said
pSivida Limited Managing Director, Dr Paul Ashton.

Diabetic retinopathy (DR), a complication of diabetes mellitus, is the
leading cause of blindness in the working-age population of developed
countries. At any time during progression of diabetic retinopathy, patients
can develop DME which involves retinal thickening of the macular area. More
than 500,000 people live with DME in the United States and this number is
expected to exceed 700,000 by the year 2010. Currently there are no FDA
approved drug treatments for DME.
