BioInvent International : partner Oxurion NV has reported topline month 3 results of Phase lla Study Evaluating THR-317 (anti-PLGF), in Combination with Ranibizumab, for DME

Lund, Sweden - August 20, 2019 - BioInvent International AB's (publ) (OMXS: BINV) partner Oxurion NV has today reported topline data from a Phase lla study evaluating THR-317, a humanized antibody against placental growth factor (PlGF), in combination with anti-VEGF (ranibizumab), an anti-vascular endothelial growth factor (VEGF) antibody, for the treatment of Diabetic Macular Edema (DME).

• Combination therapy did not show increase in best corrected visual acuity (BCVA) in the overall population at Month 3.
• Certain improvement in mean BCVA at Month 3 observed with the combination therapy in 2 pre-specified subgroups:
  • poor (or non) responders to prior anti-VEGF
  • patients with poor vision - baseline BCVA ≤65 letters.
• Topline data confirm THR-317 in combination with ranibizumab is safe and well-tolerated.

In 2017, Oxurion NV gained full and exclusive ownership of THR-317 for development and commercialization in all non-oncology indications. In exchange, BioInvent is entitled to five percent of the program's economic value.
