We Aim to Improve the Treatment of Wet AMD Through Bold Scientific Innovation

We envision a future where the impact of wet AMD is minimized and quality of vision and life is maximized.

We have a team of passionate ophthalmology and retinal experts in relentless pursuit of breakthrough therapeutic advancements and first-in-class drug candidates.

Opthea is a global biopharmaceutical company dedicated to improving and protecting vision in people with retinal disease

Opthea is boldly investigating the unmet medical need among patients with wet AMD who are receiving anti-Vascular Endothelial Growth Factor (VEGF)-A monotherapy:

Differentiated Science Based on Bold Innovation

Our lead investigational drug candidate sozinibercept (OPT-302), is a first-in-class molecule with a novel anti-VEGF-C / VEGF-D mechanism of action for use in combination with existing standard-of-care anti-VEGF-A inhibitors.8

Clinical Trials

Opthea’s lead product candidate, sozinibercept (OPT-302), is being evaluated in two pivotal Phase 3 clinical trials (COAST, NCT04757636, and ShORe, NCT04757610) for use in combination with standard-of-care anti-VEGF-A monotherapies to improve overall efficacy and deliver superior vision gains compared to standard-of-care anti-VEGF-A agents.10,11
