Dr. Chang will be joining the Summit as a presenter and a panelist: • Presentation on New Therapeutics Target RGD Integrins and The Plasma Kallikrein System: Overview of First Clinical FindingsDate & Time: April 15, 2021 at 9:55 am EDT • Participation in Q&A session entitled Targeting New Therapeutic Pathways & Looking Beyond Anti-VEGFDate & Time: April 15, 2021 at 10:35 am EDT • Participation in Panel Discussion on the Topic Searching for Novel Therapeutic Targets – Addressing Developmental Challenges for New Drug Candidates in Wet AMD & DMEDate & Time: April 15, 2021 at 11:10 am EDT For more information and registration details: https://wet-amd-drugdevelopment.com Under the leadership of Dr. Chang, Oxurion is advancing a pipeline of innovative clinical drug candidates with distinct and complementary modes of action, for treatment of retinal vascular disorders, including DME but also wet AMD. THR-149 is a potential first in class plasma kallikrein inhibitor with the possibility to become the treatment of choice for the 40% DME patients who respond sub-optimally to anti-VEGF therapy. Oxurion is currently recruiting patients in a Phase 2 and is on track to readout Part A data later this year. THR-687 is a potential best in class small molecule pan-RGD integrin antagonist initially being developed to treat DME with the possibility to become the standard of care for most DME patients. The Company is currently preparing an IND to start a Phase 2 study evaluating THR-687 as a new therapy for most DME patients. This Phase 2 is expected to start in mid-year. Beyond DME, THR-687 also has development possibilities in additional retinal vascular disorders including for wet age-related macular degeneration (Wet AMD) and retinal vein occlusion (RVO), thereby potentially allowing the Company to tap into a broader therapeutic market with a current combined estimated annual value of $12 billion.

Oxurion is aiming to build the leading global franchise in the treatment of retinal vascular disorders based on the successful development of its two novel therapeutics: THR-149, a plasma kallikrein inhibitor being developed as a potential new standard of care for the 40% of DME patients who respond sub-optimally to anti-VEGF therapy. THR-149 has shown positive topline Phase 1 results for the treatment of DME. The Company is currently conducting a Phase 2 clinical trial evaluating multiple injections of THR-149 in DME patients who previously responded sub-optimally to anti-VEGF therapy. THR-149 was developed in conjunction with Bicycle Therapeutics PLC (NASDAQ: BCYC). THR-687 is a pan-RGD integrin antagonist that is initially being developed as a potential first line therapy for DME patients. Positive topline results in a Phase 1 clinical study assessing THR-687 as a treatment for DME were announced in 2020. THR-687 is expected to enter a Phase 2 clinical trial in mid-2021. THR-687, also has the potential to deliver improved treatment outcomes for patients with wet AMD and RVO. THR-487 is an optimized compound derived from a broader library of integrin antagonists in-licensed from Galapagos NV (Euronext & NASDAQ: GLPG). Oxurion is headquartered in Leuven, Belgium, and is listed on the Euronext Brussels exchange under the symbol OXUR. More information is available at www.oxurion.com.
