Euretina Presentation “Adoption of JETREA® in My Everyday Practice” Confirms Need for a New Paradigm in Treatment of Symptomatic VMA/ VMT, Including Those Cases Associated with MH

October 1, 2013

LEUVEN, Belgium, October 1, 2013 /PRNewswire/ –

Largest ever retrospective review of VMA/VMT patients confirms early
treatment initiation may stop disease progression and lead to better visual function


        - Retrospective review of patients presenting with vitreomacular adhesion
          (VMA), vitreomacular traction (VMT), macular hole (MH) with/ without VMA, with or
          without visual symptoms (n=509)
        - Review period: July 2009 - May 2013, with mean follow up of 2.03 years.
        - VMA is a progressive disease: 16.4% of the eyes diagnosed with VMA progressed
          to VMT within one year.
        - Exact time and/or impact of progression are patient dependent.
        - Spontaneous resolution of VMA occurred in 20% of patients with VMT
        - Early treatment may be required to stop further disease progression and
          improve visual function outcome.

ThromboGenics NV (Euronext Brussels: THR:BR), a biopharmaceutical company focused on
developing and commercializing innovative ophthalmic medicines, announces that Prof. Dr.
Peter Stalmans, Department of Ophthalmology, University Hospitals Leuven, Belgium,
delivered a presentation entitled “Adoption of JETREA(R) in My Everyday Practice”, at the
recent EURETINA annual meeting of European Society of Retina Specialists in Hamburg.

In his presentation, Prof. Stalmans provided details of the largest retrospective,
observational study to date, that looked at his “real world” experience with patients with
vitreomacular adhesion (VMA), vitreomacular traction (VMT) and macular hole (MH).

Prof. Stalmans is working at a large, tertiary care ophthalmology center in Leuven
(Belgium). The Leuven center sees 50,000 ambulatory patients every year and conducts
around 2500 intravitreal injections and 7000 surgical procedures per annum. The
retrospective study is leveraging data collected from electronic medical records gathered
at the center between July 2009 and May 2013.

During EURETINA, Prof Stalmans also provided insights into his own successful clinical
experience with JETREA(R) when treating patients with early VMT and MH.

Commenting on his presentation Prof. Dr. Peter Stalmans, Department of Ophthalmology,
University Hospitals Leuven says, “This is the largest retrospective study conducted using
high resolution OCT technology. The data collected clearly shows that VMA/VMT is a
progressive condition and that spontaneous resolution of VMT is a low occurrence. Based on
our findings I believe that early treatment of these patients may be important if we are
to help them by resolving debilitating symptoms such as metamorphopsia, and further sight
threatening complications such as macular hole. My own experience of treating patients
experiencing metamorphopsia early with JETREA(R)has been extremely good with the vast
majority of patients experiencing resolution of their traction. I look forward to treating
many more patients with this novel drug which I believe will play a key role in the
treatment of a wide range of patients with VMT.”

“This new VMA/VMT patient review is the largest ever available,” says Dr. Patrik De
Haes, CEO of ThromboGenics. “For the first time, we are able to look at ‘real life’ data
provided from a tertiary center,” he continues. “We are pleased to see how the results
highlight the opportunity for JETREA(R)as an early treatment option for those patients who
would normally only be observed. These new data and ‘real life’ insights will help us to
further educate the community about the risk of disease progression and the patient
benefit of early treatment,” he concludes.
