Focus

Opthea is committed to improving vision in patients suffering from retinal eye diseases.

We are developing a novel therapeutic called OPT-302, a VEGF-C/D ‘trap’, to be used in conjunction with existing standard of care anti-VEGF-A therapies.

OPT-302 has the potential to address the unmet medical need of wet AMD and DME patients, many of whom respond sub-optimally or become refractory to existing therapies for these debilitating diseases. We are advancing the clinical development of OPT-302 in Phase 2 wet AMD and DME clinical trials.

Disease

Wet AMD is the leading cause of blindness in the developed world in people aged over 50 years. It is caused by the abnormal growth and leakage of blood vessels at the back of the eye, which causes degeneration of the retina and vision loss.

Technology

Opthea’s technology is centred on two members of the Vascular Endothelial Growth Factor (VEGF) family of proteins, VEGF-C and VEGF-D, and their activation of VEGF receptors.These proteins promote blood vessel development (angiogenesis) by binding and activating VEGFR-2 and VEGFR-3, and lymphatic vessel development (lymphangiogenesis), by activation of VEGFR-3.

Opportunity

Both wet AMD and DME are associated with vascular dysfunction and fluid accumulation at the back of the eye in a region of the central retina or ‘macula’ that is needed for sharp, central vision. Vessel growth and vascular leakage are primarily driven by members of the vascular endothelial growth factor (VEGF) family, which comprises 5 members including VEGF-A, VEGF-B, VEGF-C, VEGF-D and placenta growth factor (PlGF).

OPT-302

OPT-302, blocks two members of the vascular endothelial growth factor family, namely VEGF-C and VEGF-D, which cause blood vessels to grow and leak. Aberrant blood vessel growth and vascular leakage are hallmarks of several eye diseases including wet age-related macular degeneration (wet AMD) and diabetic macular edema (DME).

Trials

Opthea has completed a Phase 1/2a clinical trial in the US investigating OPT-302 in wet AMD patients. Opthea has completed enrolling patients in a Phase 2b clinical trial for patients with wet AMD and is currently enrolling patients in a Phase 2a clinical trial in patients with DME.
