pSivida’s Second Phase 3 Study for Durasert™ Three-year Treatment for Posterior Segment Uveitis Maintains Positive Efficacy and Safety Profile at 12 Months

Highly Significant Difference Between Durasert and Sham in Prevention of Uveitis Recurrence at 12 Months

Fiscal Q2 2018 Results Conference Call Scheduled for Today at 4:30 p.m.ET

WATERTOWN, Mass., Feb. 07, 2018 (GLOBE NEWSWIRE) --  pSivida Corp. (NASDAQ:PSDV) (ASX:PVA), a leader in the development of sustained release drug products and technologies, today announced that results from the Company's second Phase 3 trial for Durasert three-year treatment for posterior segment uveitis confirmed a significant reduction in uveitis recurrence rate at 12 months. The study involved 153 patients with posterior segment uveitis and the primary endpoint was prevention of recurrence of posterior uveitis at six months with patients continuing to be followed for 36 months. The key highlights from the trial at 12 months included:

  • A significant reduction in the recurrence of posterior segment uveitis through 12 months; 36.6% of Durasert-treated patients had a recurrence compared to 71.2% of patients in the sham group (p<0.001).
  • A mean increase of intraocular pressure (IOP) of 2.0 and 0.0 mm Hg at 12 months over a baseline IOP of 13.3 and 13.1 mm Hg for Durasert and sham, respectively.
  • Patients requiring IOP-lowering therapy at any time during the first 12 months of follow-up were 50.5% for Durasert and 51.9% for sham. Only one patient, assigned to Durasert, required IOP surgery during the first 12 months of follow-up.
  • In patients with a natural (phakic) lens at baseline, 18.0% in the Durasert group required cataract surgery through 12 months compared to 8.6% in the sham group. 

"The continued positive efficacy and safety data for Durasert, now confirmed in two separate Phase 3 studies at both six and 12 months, is encouraging for patients that are suffering from posterior segment uveitis,” commented by Glenn J. Jaffe, M.D., Chief, Division of Retinal Ophthalmology, Duke University, and a primary clinical investigator in the phase 3 program.  “While today’s standard of care treatment options are mainly directed at controlling flares, Durasert is designed to help prevent flares for up to three years with a single injection administered in an office setting.”

“As we await the US Food and Drug Administration’s (FDA) decision on acceptance of our New Drug Application (NDA) submitted in January, we are solidifying our go-to-market plan,” added Nancy Lurker, President and CEO of pSivida.  “We continue to receive highly positive feedback from specialists regarding Durasert three year for posterior segment uveitis, which bolsters our team’s confidence that there will be strong interest to treat patients dealing with this devastating disease, which is the third leading cause of blindness, pending a favorable regulatory review.”
