About Opthea Ltd

https://opthea.com/

Opthea is a clinical-stage biopharmaceutical company focused on developing novel therapies for vision-threatening retinal diseases, particularly wet age-related macular degeneration (wet AMD) and diabetic macular edema (DME). The company's lead product candidate, sozinibercept, is a first-in-class biologic 'trap' inhibitor targeting Vascular Endothelial Growth Factors C and D (VEGF-C and VEGF-D). Sozinibercept is being developed for administration in combination with standard-of-care anti-VEGF-A therapies. This dual-pathway inhibition aims to deliver superior visual outcomes by more comprehensively blocking the mechanisms that contribute to disease progression, addressing the limitations of current treatments that only target VEGF-A. The therapy is being evaluated in late-stage pivotal clinical trials for wet AMD.
