A Multicenter Study to Compare Multiple Doses of Intravitreal Microplasmin Versus Sham Injection for Treatment of Patients With Diabetic Macular Edema (DME)


A multicenter study to compare multiple doses of intravitreal microplasmin for non-surgical PVD induction for treatment of patients with DME.

Full Title of Study: “A Randomized, Sham-Injection Controlled, Double-Masked, Ascending-Dose, Dose-Range-Finding Trial of Microplasmin Intravitreal Injection for Non-Surgical Posterior Vitreous Detachment (PVD) Induction for Treatment of DME.”

Clinical Trial Outcome Measures

Primary Measures

  • PVD Induction
    • Time Frame: Day 14 post-injection
    • The primary efficacy variable was the proportion of patients with total posterior vitreous detachment (PVD) on Day 14 as determined by a masked central reading center (CRC) using 4-quadrant B-scan and optical coherence tomography (OCT)
