PSIVIDA CORP. REPORTS FIRST QUARTER

FISCAL YEAR 2013 RESULTS

WATERTOWN, MA – November 8, 2012 — pSivida Corp. (NASDAQ: PSDV, ASX: PVA), a leader in developing sustained release, drug delivery products for treatment of back-of-the-eye diseases, today announced financial results for its first quarter ended September 30, 2012.

“We are very pleased that the FDA has cleared us to proceed directly to two pivotal Phase III clinical trials of our lead development product, an injectable micro-insert for posterior uveitis,” said Dr. Paul Ashton, President and CEO. “We intend these trials, which we plan to begin next year, to form the basis for a future NDA submission. We are also pleased with the progress and initial results of pre-clinical studies of applications of Tethadur™, our protein/anti-body delivery technology platform.”

“With respect to the posterior uveitis micro-insert, the FDA’s decision to allow us to reference much of the ILUVIEN^® data for diabetic macular edema (DME), including the clinical safety data, from Alimera Sciences’ already-completed pivotal Phase III clinical trials, has the potential to both simplify any future NDA submission and to shorten development time. We are planning to target enrollment of a total of 300 patients in our two trials, with a primary end point of recurrence of uveitis at 12 months. Because this development product uses the same micro-insert used in ILUVIEN for DME, which delivers a smaller dosage of the same drug as our Retisert^® product already approved for posterior uveitis, we expect our trials will show efficacy similar to Retisert but with a side-effect profile in uveitis patients comparable to that seen in DME patients. We are optimistic therefore that our micro-insert will be efficacious for posterior uveitis, with a favorable risk/benefit profile and fewer side effects compared to Retisert,” continued Dr. Ashton.

Tethadur, the Company’s protein/anti-body delivery platform, has the potential to provide sustained release of peptides and proteins in many therapeutic areas and is currently being evaluated in ophthalmology under an agreement with a leading global biopharmaceutical company. In the ophthalmic area, a sustained delivery system like Tethadur for these types of molecules could offer a significant clinical advance because they must currently be injected into the eye every one or two months.

Regarding the European commercialization of ILUVIEN for DME, Alimera Sciences, pSivida’s licensee, has announced a planned direct commercial launch in three EU countries in 2013, with Germany expected in the first quarter, the United Kingdom in the second quarter and France in the third quarter. ILUVIEN has received marketing authorization in the United Kingdom, Austria, Portugal, France and Germany, and has been recommended for marketing authorization in Italy and Spain, for the treatment of vision impairment associated with chronic DME considered insufficiently responsive to available therapies. Alimera completed a $40 million financing to proceed with the direct commercialization of ILUVIEN for DME in Germany, the U.K. and France. Alimera has estimated that there are approximately one million people suffering from DME in the 7 EU countries where marketing authorization has either been received or recommended.

Alimera also announced that it intends to resubmit the NDA for ILUVIEN for DME to the FDA during the first quarter of 2013. Alimera further announced that using data from its two previously completed pivotal Phase III clinical trials, the resubmission will focus on the population of patients with chronic DME, the same group for which marketing approval for ILUVIEN has been granted in various EU countries. Approval in the U.S. would entitle pSivida to a $25 million milestone payment and 20% of net profits, as defined, from U.S. sales of ILUVIEN by Alimera.

The investigator-sponsored Phase I/II dose-escalation study of pSivida’s bioerodible, injectable latanoprost micro-insert for glaucoma and ocular hypertension is ongoing. Pfizer has an exclusive option under various circumstances to license the development and commercialization worldwide of this micro-insert for human ophthalmic disease other than uveitis.

Revenues for the fiscal 2013 first quarter were $553,000 compared to $1.7 million for the first quarter a year earlier. The fiscal 2012 first quarter included $1.1 million of revenue recognition from the termination of a 2008 nutraceutical field of use license. pSivida reported a net loss of $2.6 million, or $0.11 per share, for the first quarter ended September 30, 2012, compared to a net loss of $2.4 million, or $0.12 per share, for the first quarter of the prior year.

At September 30, 2012, cash, cash equivalents and marketable securities totaled $17.6 million, reflecting $4.7 million in net proceeds from an August registered direct offering of shares of common stock and warrants.
