WATERTOWN, Mass., Aug. 15, 2016 (GLOBE NEWSWIRE) -- pSivida Corp. (NASDAQ:PSDV) (ASX:PVA), a leader in the development of sustained release drug delivery products primarily for eye diseases, announced that Dr. Glenn J. Jaffe, Robert Machemer Professor of Ophthalmology at Duke University School of Medicine in Durham, NC and the principal investigator on the first of pSivida's two Phase 3 trials of Medidur for recurrent non-infectious uveitis affecting the posterior segment of the eye, presented the topline results from the trial through its six-month primary endpoint and through 12 months of follow-up. Dr. Jaffe's presentation, "A Randomized,
Masked, Controlled, Safety and Efficacy Study of an Injectable Fluocinolone Acetonide (FA) Intravitreal Insert in Non-Infectious Uveitis" took place at the Inflammatory and Infectious Disease session of the American Society of Retinal Specialists Annual Meeting, on Sunday, August 14, in San Francisco.
This was the first scientific presentation of the topline results from this Phase 3 trial, which met its primary end point, prevention of recurrence of disease at six months, with high statistical significance (p less than 0.00000001, intent to treat analysis) maintained through 12 months. In addition to data on prevention of recurrence of disease, Dr. Jaffe presented data on additional exploratory analyses on improvement of visual acuity, elimination of systemic treatments (which can cause serious side effects), and safety results including incidence of cataract and elevated intraocular pressure (which can be a result from the disease itself as well as from steroid treatment).
"Medidur's performance has continued to exceed our expectations in this phase 3 trial through the latest follow up," said Dr. Paul Ashton, president and chief
executive officer of pSivida Corp. "This trial's results demonstrated that Medidur - administered by injection in an office setting - can prevent recurrence of disease on a long-term basis while maintaining a favorable safety profile. Medidur has the potential to be a promising new treatment for patients with posterior uveitis who have limited options to control their disease effectively."
About Medidur. Medidur is an injectable micro-insert designed to treat posterior uveitis. Injected into the back of the eye in an office procedure, it provides sustained release of 0.18 mg of the corticosteroid fluocinolone acetonide at a controlled rate directly to the retina for three years.
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 affects 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 Phase 3 Trials. pSivida is conducting two Phase 3 trials to assess the safety and efficacy of Medidur for the treatment of posterior uveitis. These are randomized, sham-controlled, double-masked trials. The primary endpoint of both trials is recurrence of posterior uveitis at six months, with patients in both trials followed for three years. The first Phase 3 Medidur trial, which is fully enrolled with 129 patients in 16 centers in the U.S. and 17 centers outside the U.S., met its primary efficacy endpoint with high statistical significance. The second trial, which will include up to 150 patients in approximately 15 centers in India, is currently being enrolled.
