pSivida CEO to Discuss Sustained Delivery and Nanotechnology in Ophthalmology at Upcoming Massachusetts Biotechnology Council Meeting

WATERTOWN, Mass.--(BUSINESS WIRE)-- pSivida Corp. (NAS: PSDV) (ASX:PVA), a leader in developing sustained release, drug delivery products for treatment of back-of-the-eye diseases, today announced that its President and CEO, Dr. Paul Ashton, will discuss "Cross Fertilization: Sustained Delivery and Nanotechnology in Ophthalmology" at an upcoming Formulation and Drug Delivery Committee Meeting of the Massachusetts Biotechnology Council on Wednesday, October 17.


Dr. Ashton's presentation will focus on delivery of peptides and proteins, primarily in ophthalmology. Currently the eye space is dominated by two anti-VEGF proteins, Roche/Genentech's Lucentis® and Regeneron's Eyelea.® Both of these drugs must be repeatedly injected directly into the eye, typically every one to two months. "The development of a sustained release protein delivery system would offer a significant advantage in ophthalmology," said Dr. Paul Ashton, president and chief executive officer of pSivida. "pSivida is presently developing such a delivery system, called Tethadur™, which is based on the company's BioSilicon technology platform. This delivery system could also have a significant clinical impact outside of ophthalmology for diseases requiring systemic administration, particularly in the BioSimilars era."

Tethadur is designed to provide sustained delivery of biologic molecules, including proteins, antibodies and peptides. It is composed of nanostructured porous material, in which the sizes of the pores are manufactured to accommodate specific protein, peptide or antibody molecules. "Very simply put, Tethadur can be viewed as a high tech egg box where each protein molecule is contained in its own spot until it is released," said Dr. Ashton. "We are able to control the release rate of a drug by controlling the pore size of the Tethadur delivery material."

pSivida recently announced a technology evaluation agreement with a leading global biopharmaceutical company to evaluate Tethadur in the field of ophthalmology. "Although we are at the very early stages with Tethadur, the potential improvement in patient care and clinical outcomes could be highly significant," Dr. Ashton stated. "We have already been successful in this field, working with partners we have developed three of the four sustained release devices for ophthalmic drugs approved in either the US or the EU."

About pSivida Corporation

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 Diabetic Macular Edema (DME), licensed to Alimera Sciences, Inc., has received marketing authorization in Austria, France, Germany, Portugal and the U.K. and is awaiting authorization in Italy and Spain. The United States Food and Drug Administration (FDA) has cleared pSivida's Investigational New Drug application (IND) to treat posterior uveitis with the same micro-insert. An investigator-sponsored clinical trial is ongoing for an injectable, bioerodible micro insert to treat glaucoma and ocular hypertension. pSivida's two FDA-approved products, Retisert® and Vitrasert®, are implants that provide long-term, sustained drug delivery to treat two other chronic diseases of the retina.
