Highly Significant Difference Observed Between Durasert and Control Group
in Primary Efficacy Analysis of Prevention of Uveitis Recurrence
Conference Call Today at 4:30 p.m.ET
WATERTOWN, Mass., June 13, 2017 (GLOBE NEWSWIRE) -- pSivida Corp. (NASDAQ:PSDV) (ASX:PVA), a leader in the development of sustained release drug products and technologies, today announced the Company's second Phase 3 trial of Durasert three-year treatment for posterior segment uveitis achieved the trial's primary endpoint. The study involved 153 patients and the primary endpoint was prevention of recurrence of posterior uveitis at six months with patients continuing to be followed for 36 months. Durasert three-year insert demonstrated a significant reduction in the recurrence of posterior segment uveitis through six months; 21.8% of Durasert-treated
patients had a recurrence compared to 53.8% of patients in the sham group (p < 0.001).
"The data from this trial confirms previous clinical research demonstrating our three-year Durasert insert for posterior segment uveitis may significantly help patients suffering from this devastating disease -- the third leading cause of blindness," said Nancy Lurker, President and CEO of pSivida Corp. "Our market research indicates strong interest in using the product driven by the results of our first Phase 3 clinical trial. We continue to expect the submission of the European Market Authorization Application (MAA) by the end of June, and we remain on track to also file a New Drug Application (NDA) with the FDA in the calendar fourth quarter of 2017."
safety results from the trial included:
- Intraocular pressure (IOP) elevation, which can lead to glaucoma, was 2.4 and 1.3 mm Hg (mean) at six months (vs baseline) for Durasert and sham, respectively.
- Patients requiring IOP-lowering therapy at any time during the first six months follow-up were 41.6% for Durasert and 34.6% for sham. No subject required IOP surgery during the first six months of follow-up.
- In patients with a natural (phakic) lens at baseline, 4.9% in the Durasert group required a cataract surgery through six months compared to 8.6% in the sham group.
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 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.
"The results of the second Phase 3 study confirm the efficacy and safety profile of the Durasert three-year insert demonstrated in the first Phase 3 study. Consistent, durable control of chronic posterior segment uveitis is a critical goal of treatment. The
three-year Durasert insert has the potential to be the first product approved to help prevent the recurrence of this devastating condition for up to three years with a single intravitreal injection," commented Dr. Jyotirmay Biswas, Professor of Ophthalmology and Director of Uveitis & Ocular Pathology Department, Sankara Nethralaya Ophthalmic Center, Tamil Nadu, India and primary investigator of the study.
"Chronic posterior uveitis is challenging to treat as the disease tends to wax and wane over time. Durasert three-year insert is a single-injection office-based treatment that can last 2-3 years. Therefore, it addresses the need to help prevent recurrences over an extended time period, rather than to treat them episodically, and may represent an exciting new approach to manage
these patients," added Dr. Glenn J. Jaffe, Robert Machemer Professor of Ophthalmology at Duke University School of Medicine in Durham, NC and one of the world's leading uveitis experts.
