THROMBOGENICS : ' JETREA® Gains Approval in Brazil

Leuven, March 16, 2015 - ThromboGenics NV (Euronext Brussels: THR), an integrated biopharmaceutical company focused on developing and commercializing innovative ophthalmic medicines, today announces that JETREA® (ocriplasmin) has gained approval in Brazil.

JETREA^® has been indicated for the treatment of adults with vitreomacular traction (VMT), including when associated with macular hole of diameter less than or equal to 400 microns.

If left untreated, VMT generally leads to significant visual distortion, deterioration in visual acuity, or even central blindness. With JETREA^®, retina physicians in Brazil will have access to the world's first and only pharmacological treatment option for VMT, allowing them to intervene earlier and potentially stop the progression of this debilitating disease.

ThromboGenics' partner Alcon, which is commercializing JETREA^® outside the US, will be responsible for the launch of the drug in Brazil.

About JETREA^® (ocriplasmin)

JETREA^® (ocriplasmin) is a truncated form of human plasmin. In the US, JETREA^® is indicated for the treatment of symptomatic VMA. In Europe, JETREA^® is indicated for the treatment of vitreomacular traction (VMT), including when associated with macular hole of diameter less than or equal to 400 microns. JETREA^® is a selective proteolytic enzyme that cleaves fibronectin, laminin and collagen, three major components of the vitreoretinal interface that play an important role in vitreomacular adhesion.

JETREA^® has been evaluated in two multi-center, randomized, double-masked Phase III trials conducted in the U.S. and Europe involving 652 patients with vitreomacular adhesion. Both studies met the primary endpoint of resolution of VMA at day 28.

JETREA's Phase III program found that 26.5% of patients treated with ocriplasmin saw resolution of VMA, compared with 10.1% of patients receiving placebo (p<0.01). The Phase III program also showed that JETREA was generally well tolerated with most adverse events being transient and mild in severity.
