Oxurion Enrolls First Patient in Phase 2 Clinical Study Evaluating THR-317 (anti-PlGF) for treatment of Idiopathic Macular Telangiectasia Type 1 (MacTel 1)

Leuven, Belgium, 20 September 2018 - Oxurion NV (Euronext Brussels: OXUR), a biopharma company ( formerly known as ThromboGenics ) focused on developing treatments for back of the eye diseases with an innovative pipeline in diabetic eye disease, announces that it has enrolled the first patient in a Phase 2 open-label multi-centre study evaluating the efficacy and safety of intravitreal THR-317, an anti-PIGF (human placental growth factor) antibody, for the treatment of Macular Telangiectasia Type 1 (MacTel 1)

MacTel 1 is a rare disease that affects the macula and can lead to vision loss. There is currently no cure or effective treatment for MacTel 1.

This Phase 2 study (THR-317-003 - NCT03669393 ) plans to enrol 10 patients with macular edema caused by MacTel 1, who will each receive 3 intravitreal THR-317 injections over a period of 2 months. Efficacy and safety of the therapy will be assessed via functional and anatomic endpoints.

This clinical trial is being conducted in line with the Oxurion strategy and mission to expand its focus on developing treatments for other back of the eye diseases, in addition to its novel diabetic eye disease pipeline.

Patrik De Haes, MD, Oxurion CEO, commented: " The start of this Phase 2 study is an important step as we look to expand into additional back of the eye disorders, in line with our mission to enhance vision and fight blindness, alongside our diabetic eye disease pipeline, for which multiple important milestones have been achieved over recent months. Research suggests that PIGF could have an important role to play in MacTel 1, leading us to assess the potential of our anti-PIGF candidate THR-317 in a new eye disease area. "

About Macular Telangiectasia Type 1

Macular Telangiectasia (MacTel), or idiopathic macular telangiectasia, is a rare degenerative retinal disease with characteristic alterations of the retinal vasculature and macula degeneration. There are two distinct types of MacTel, describing distinct clinical entities: Type 1, "aneurysmal telangiectasia," and Type 2, "perifoveal telangiectasia".  MacTel 1 typically affects one eye and most commonly presents in men of 40 years to 50 years of age. In MacTel 1, capillaries of the macula become dilated and aneurysms form, causing swelling, disrupting blood flow and often leading to leakage from the blood vessels. Unlike in MacTel Type 2, neovascularisation as a result of this damage does not usually occur.
