pSivida Files NDA for Eye Disease
pSivida Corp. has submitted an NDA for Durasert, a three-year sustained-release implant containing the corticosteroid fluocinolone acetonide for treating posterior segment uveitis. The submission includes data from two Phase 3 studies that achieved the primary efficacy endpoint, according to the company. The most recent study reported last year 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. The product “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).” pSivida says.
Posterior segment uveitis is a chronic, non-infectious inflammatory disease affecting the posterior segment of the eye and often involving the retina. It affects people of all ages and can destroy eye tissues, leading to severe vision loss and blindness. In the U.S., posterior uveitis affects between 80,000 and 100,000 people, the company says.
