About ThromboGenics

ThromboGenics is a biopharmaceutical company focused on developing and commercializing innovative ophthalmic medicines. The company's lead product, ocriplasmin, has successfully completed two Phase III clinical trials for the pharmacological treatment of symptomatic vitreomacular adhesion (VMA). The MAA for ocriplasmin has been accepted for review in Europe and the BLA will be re-submitted in the U.S. by April 2012. Ocriplasmin is in Phase II clinical development for additional vitreoretinal conditions.

In March 2012, ThromboGenics signed a strategic partnership with Alcon (Novartis) for  the commercialization of ocriplasmin outside the United States. Under this agreement, ThromboGenics could receive up to a total of €375 million in up-front and milestone payments, plus an attractive level of royalties on Alcon's net sales of ocriplasmin. ThromboGenics and Alcon intend to share the costs equally of developing ocriplasmin for a number of new vireoretinal indications.

ThromboGenics is also developing two novel antibody therapeutics in collaboration with BioInvent International. These are TB-402 (anti-Factor VIII), a long-acting anticoagulant in Phase II, and TB-403 (anti-PlGF), in Phase Ib/II for cancer which has been partnered with  Roche.

ThromboGenics is headquartered in Leuven, Belgium. The Company is listed on the NYSE Euronext Brussels exchange under the symbol THR. More information is available at http://www.thrombogenics.com.
