pSivida Announces Top-Line Results From Investigator-Sponsored Phase II Study Of Medidur For Uveitis To Be Reported Next Week

Dr. Glenn J. Jaffe to Present at 33^rd Annual Scientific Meeting of American Society of Retina Specialists

WATERTOWN, Mass.--(BUSINESS WIRE)--pSivida Corp. (NASDAQ:PSDV) (ASX:PVA), a leader in the development of sustained release drug delivery products for treating eye diseases, announced that top line results from an investigator-sponsored, Phase II study of pSivida’s Medidur for uveitis will be presented at the 33^rd Annual Scientific Meeting of the American Society of Retina Specialists (ASRS) meeting to be held July 10-14 in Vienna, Austria. Dr. Glenn J. Jaffe, Robert Machemer Professor of Ophthalmology at Duke University School of Medicine in Durham, NC, who is conducting this study, will make the presentation. He also serves as principal investigator in pSivida’s first pivotal Phase III trial for Medidur for posterior uveitis, which is currently underway.

The American Society of Retina Specialists, a non-profit corporation, provides a scientific forum to promote the advancement of vitreoretinal diseases and surgery to its more than 2,600 members in the United States, Puerto Rico and 59 countries.

About Medidur. Medidur is an injectable micro-insert designed to treat posterior uveitis that provides sustained release of flucinolone acetonide (a corticosteroid) for three years. Medidur comprises the same micro-insert (same design, same polymers, same drug, same dose) as ILUVIEN® for DME. ILUVIEN has been approved in the U.S. and 17 EU countries and is sold in the U.S., the U.K., Germany and Portugal.

About Posterior Uveitis. Posterior uveitis is a chronic, non-infectious inflammatory disease affecting the posterior segment of the eye, often involving the retina, which is a leading cause of blindness in the developed and developing countries. It afflicts people of all ages, producing swelling and destroying eye tissues, which can lead to severe vision loss and blindness. In the U.S. posterior uveitis is estimated to affect approximately 175,000 people, resulting in approximately 30,000 cases of blindness and making it the third leading cause of blindness in the U.S.

Patients with posterior uveitis are typically treated with systemic steroids but over time frequently develop serious side effects that can limit effective dosing. Patients then often progress to steroid-sparing therapy with systemic immune suppressants or biologics, which themselves can have severe side effects including an increased risk of cancer. Medidur is designed to provide improved outcomes compared to standard of care but with a significant reduction in side effects.

About Medidur’s Phase III Trials. pSivida’s two Phase III trials for Medidur are double-blind studies comparing injections of Medidur to sham injections on a two-to-one basis. The first trial is fully enrolled with 129 patients in 16 centers in the U.S. and 17 centers outside the U.S. The primary end point of the first trial is recurrence of posterior uveitis within one year. The last scheduled visit for the last patient in this trial is in March 2016, and top-line data is expected in the second quarter of 2016. The second trial will enroll up to 150 patients in approximately 15 centers in India. The primary endpoint of the second trial is recurrence of posterior uveitis within six months. Patients in both trials will be followed for three years. pSivida’s plans to seek approval for Medidur for posterior uveitis based on 12-month data from the first Phase III trial, six-month data from the second Phase III trial and data from a utilization study of pSivida’s redesigned proprietary inserter together with data referenced from the Phase III trials of ILUVIEN for DME. With favorable results, pSivida expects to file a New Drug Application in the first half of 2017.
