LEUVEN, Belgium, April 1 /PRNewswire-FirstCall/ --

- Trial Results Expected Mid-2008

ThromboGenics NV (Euronext Brussels: THR), a biotechnology company focused on vascular diseases, eye diseases and cancer, today announces that it has completed patient enrolment for its Phase IIb MIVI III trial in the United States. This study is designed to evaluate the safety and efficacy of Microplasmin in vitrectomy (MIVI III - Microplasmin for Vitreous Injection).

A vitrectomy is a surgical procedure carried out in the treatment of many back of the eye diseases such as retinal detachment, diabectic vitreous hemorrhage and macular hole. Vitrectomy is used to induce a posterior vitreous detachment (PVD) which involves removing the vitreous via suction. Microplasmin is a proteolytic enzyme that cleaves important molecules which link the vitreous to the retina and therefore has the potential to facilitate vitrectomy and induce PVD without the risks inherent in detachment by surgical intervention.

MIVI III is a Phase IIb, randomized, double-masked, placebo-controlled, dose-ranging trial evaluating three doses of Microplasmin (25, 75 and 125 μg) versus placebo in 120 patients scheduled for vitrectomy. The trial is taking place across 19 sites throughout the United States and is assessing the safety and efficacy of Microplasmin intravitreal injection 7 days prior to vitrectomy. Top-line, unmasked results of this trial are expected in June 2008.

Dr. Steve Pakola, Chief Medical Officer of ThromboGenics, commenting on today's announcement, said: "We are very pleased to have completed enrolment in our lead program. Microplasmin has the potential to significantly change the way we treat back of the eye diseases and this study will bring us a step closer to realising this potential. Due to encouraging safety and efficacy results obtained from both the MIVI I and MIVI II Traction Phase II trials which were conducted in Europe, we are confident that
