ThromboGenics NV - Business Update

Leuven, Belgium – 5 November, 2010 – ThromboGenics NV (Euronext Brussels: THR), a biopharmaceutical company focused on the discovery and development of innovative treatments for eye disease, cardiovascular disease and cancer, is today issuing a business update for the period ending 30 September, 2010.

Patrik De Haes, CEO of ThromboGenics, commenting on today’s announcement said: “During 2010 we have made significant steps toward our goal of becoming a profitable fully integrated ophthalmology company focused on transforming the treatment of retinal disorders. In August, we announced positive results from our second pivotal Phase III trial with microplasmin, confirming the findings of the first study, which were announced in April. These studies showed that a single intravitreal injection of microplasmin has the ability to resolve vitreomacular adhesion (VMA) in close to 30% of patients and to cure a significant proportion of patients (40%) with full thickness macular hole without the need for surgery. We believe that these very important clinical findings demonstrate microplasmin’s potential to have a major impact on the treatment of retinal disorders.”

Dr. De Haes continued, “Our confidence in the potential of microplasmin has been reinforced by a recent market research study with vitreoretinal specialists, which showed that a high proportion of clinicians would be willing to use this innovative new treatment based on the Phase III clinical data we have generated. We are also making good progress in recruiting the experienced commercial team needed to ensure that we are in a position to launch microplasmin successfully in the U.S. and Europe. The next twelve months will be another exciting period for ThromboGenics as we look to deliver a number of important milestones that will create further significant shareholder value.”

Financial Update - As of 30 September, 2010, ThromboGenics had €59.1 million in cash and cash investments. This compares to €76.7 million at 31 December 2009 and €61.2 million on 30 June 2010. The end of June 2010 cash figure does not include a €6 million milestone payment from Roche relating to TB-403 that was received in July. The current level of cash resources is expected to allow ThromboGenics to execute its operational plans for approximately the next two years.

- ThromboGenics achieved revenues of €6.1 million during the first nine months of 2010 versus €3.7 million in the same period of 2009. Nearly all of this revenue came from the Roche milestone payment. R&D expenses were €12.8 million during the first nine months, versus €12.6 million in the same period in 2009, as the Company invested in the development of its attractive product pipeline. In addition, €7.0 million of costs related to the microplasmin Phase III clinical program MIVI-TRUST have been capitalized. This compares to €10.4 million in the corresponding period in 2009.
