pSivida Announces FDA Acceptance For Filing of New Drug Application (NDA) for Durasert™ Three-Year Treatment for Posterior Segment Uveitis

WATERTOWN, Mass., March 19, 2018 (GLOBE NEWSWIRE) -- pSivida Corp. (NASDAQ:PSDV) (ASX:PVA), a leader in the development of sustained release drug products and technologies, today announced that its New Drug Application (NDA) for Durasert three-year treatment for posterior segment uveitis has been accepted by the U.S. Food and Drug Administration (FDA) for filing. The acceptance of the NDA reflects the FDA's determination that the application is sufficiently complete to permit a substantive review. The application will be subject to a standard review and will have a Prescription Drug User Fee Act (PDUFA) date of November 5, 2018. The PDUFA date is the goal date for the FDA to complete its review of the NDA.

The NDA includes data from two Phase 3 studies that each successfully achieved the primary efficacy endpoint at six months with a p value < 0.001. In addition, the safety profile in patients treated with Durasert three-year for posterior segment uveitis was consistent with the safety profile of steroid treatments that are currently considered standard of care for this disease. 

"The FDA's acceptance for review of our Durasert NDA submission is a major milestone for pSivida and we look forward to continuing to work with the FDA as they review our application," commented Nancy Lurker, President and CEO.  "Given the high unmet medical need, we believe that Durasert, if approved, has the potential to become an important new treatment option for the thousands of patients suffering from posterior segment uveitis, the third leading cause of blindness."

About Posterior Segment Uveitis
Posterior segment uveitis is a chronic, non-infectious inflammatory disease affecting the posterior segment of the eye, often involving the retina, which is believed to be a leading cause of blindness in the developed and developing countries. It affects people of all ages, producing swelling and destroying eye tissues, which can lead to severe vision loss and blindness. In the U.S., posterior segment uveitis affects between 80,000 - 100,000 people. Today, 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.
