Solving the unmet need of superior vision
Sozinibercept is a novel, first-in-class VEGF-C/D ‘trap’ inhibitor designed to be used in combination with standard-of-care anti-VEGF-A therapies, with the potential to deliver superior visual outcomes.



VEGF-C/D ligands are upregulated in patients receiving anti-VEGF-A therapies causing the formation of leaky blood vessels which may lead to vision loss and drive disease progression.
Sozinibercept traps VEGF-C and VEGF-D protein ligands to inhibit VEGF-C/D mediated angiogenesis through VEGFR-2 and VEGFR-3 receptors.
By preventing blood vessel growth and vascular leakage in the retina, sozinibercept has the potential to deliver superior visual outcomes when used in combination with standard-of-care anti-VEGF-A therapies.
How Sozinibercept Works In The Eye
Through our bold innovation, we seek to transform the lives of people living with blinding diseases including wet AMD.
Our novel, first-in-class VEGF-C/D ‘trap’ inhibitor has the potential to deliver superior visual outcomes in combination with standard-of-care.
Opthea’s lead product candidate, sozinibercept is the only drug in late-stage clinical development for wet AMD with the potential to be the first product in 20 years to deliver superior visual gains for patients suffering from this debilitating disease.
