  pSivida CEO to Discuss Sustained Delivery of Antibodies in Ophthalmology and
  Systemic Disease at International Symposium on Integrated Functionalities

Business Wire

WATERTOWN, Mass. -- July 29, 2013

pSivida Corp. (NASDAQ:PSDV), a specialty pharmaceutical company that is a
leader in developing sustained release drugs for treatment of back-of-the-eye
diseases, has announced that pSivida President and Chief Executive Officer,
Paul Ashton, Ph.D., will speak today at the International Symposium on
Integrated Functionalities 2013 meeting at the Hilton DFW Lakes Executive
Conference Center in Grapevine, Texas.

Dr. Ashton’s talk, “Materials Science to Bridge Biologic Breakthrough to
Therapeutic Breakthrough,” will focus on pSivida’s Tethadur™ platform and
sustained delivery of antibodies in ophthalmology and systemic disease.
Tethadur is an application of pSivida’s BioSilicon™ technology platform
designed to provide sustained delivery of large biologic molecules, including
proteins, antibodies and peptides. BioSilicon utilizes an injectable,
bioerodible, nanostructured, porous BioSilicon material for drug delivery. The
sizes of the pores in the BioSilicon material are manufactured using
nanotechnology to accommodate specific protein, peptide or antibody molecules
that are then released at a controlled, sustained rate. The technology also
has significant potential for use in many applications.

The symposium brings together leaders in fundamental and applied science in
materials integration, design and fabrication. The meeting has been sponsored
by the Materials Research Society since 1987.

About pSivida

pSivida Corp., headquartered in Watertown, MA, develops tiny, sustained
release, drug delivery products designed to deliver drugs at a controlled and
steady rate for months or years. pSivida is currently focused on treatment of
chronic diseases of the back of the eye utilizing its core technology systems,
Durasert™ and BioSilicon™. The injectable, sustained release micro-insert
ILUVIEN® for the treatment of chronic DME considered insufficiently responsive
to available therapies, licensed to Alimera Sciences, Inc., has received
marketing authorization in Austria, France, Germany, Portugal, Spain and the
U.K. and is awaiting authorization in Italy. Alimera has resubmitted the New
Drug Application for ILUVIEN for DME to the U.S. Food and Drug Administration.
pSivida plans to institute pivotal Phase III clinical trials for the treatment
of posterior uveitis, a chronic back-of-the-eye disease, with the same
micro-insert as ILUVIEN for DME. An investigator-sponsored clinical trial is
ongoing for an injectable, bioerodible micro-insert to treat glaucoma and
ocular hypertension. pSivida's FDA-approved Retisert® licensed to Bausch &
Lomb Incorporated provides long-term, sustained drug delivery to treat
posterior uveitis.
