About Medidur. Medidur is an injectable micro-insert designed to
treat posterior uveitis that provides sustained release of flucinolone
acetonide (a corticosteroid) for three years. Medidur comprises the same
micro-insert (same design, same polymers, same drug, same dose) as
ILUVIEN® for DME. ILUVIEN has been approved in the U.S. and 17 EU
countries and is sold in the U.S., the
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 is estimated to affect 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's Phase III Trials. pSivida's two Phase III trials
for Medidur are double-masked studies comparing injections of Medidur to
sham injections on a two-to-one basis. The primary end point of both
trials is recurrence of uveitis within six months. The first trial is
fully enrolled with 129 patients in 16 centers in the U.S. and 17
centers outside the U.S. The last scheduled visit for the last patient
in this trial is in
