The World’s First Endothelial Dysfunction Blocker

|---|---|
| CU06 | The World’s First Endothelial Dysfunction Blocker (Endothelial Dysfunction Blocker) • CU06 is a small molecule developed using SOLVADYS™ platform technology and is the world’s first endothelial dysfunction blocker that strongly inhibits damage, hyperpermeability, and inflammation of endothelial cells. • CU06, a treatment for intractable vascular diseases caused by various endothelial cell dysfunction, has been out-licensed to Thea, a French ophthalmology company in October 2021. US Phase 1 clinical trial has been completed in June 2022. |
| Indication | • Diabetic Macular Edema, Wet Age-related Macular Degeneration |
| Unmet Needs | • Non-response or poor response rate to the current Anti-VEGF treatment: is around 40% • Risk of inflammation, pain, and fear due to intraocular injection |
| Mechanism of Action | • Fundamentally inhibits hyperpermeability by stabilizing endothelial cell junctions through modification of vascular endothelial cell actin structure. • Inhibits NF-κB inflammatory signaling pathway in vascular endothelial cells • Enhances survival rate and protection for vascular endothelial cells |
| Efficacy & Safety | • In vivo anti-hyperpermeability efficacy of CU06 was determined in endothelial cell (EC) dysfunction-related disease models. • Oral administration of CU06 inhibited retinal vascular leakage in VEGF or Angiopoietin-2 (Ang2) induced vascular leakage mouse model, Streptozotocin (STZ)-induced diabetic retinopathy mouse model and, CNV model in beagles. |
| Market | • 3.5 billion US$ in 2016 • Forecasted to be 6.66 billion US$ by 2026 |
Indication
Diabetic macular edema
Diabetic macular edema is a disease in which liquid penetrates and swells into the macula, the light sensory layer, leading to blindness from aggravation of symptoms. Although anti-VEGF injections are used, treatment is clearly limited due to a high nonresponse rate and concerns about side effects such as increased intraocular pressure, cataract, and inflammation. So, there is an urgent need to develop a drug with a novel approach with the convenience of use for patients.

Wet age-related macular degeneration
It is a disease in which degeneration occurs in the macula, the nervous tissue that enables you to see objects in the fovea (the center of the inner retina of the eye) clearly and causes symptoms such as decreased vision or vision distortion (metaplasia). Age-related macular degeneration can be broadly divided into non-exudative (dry) and exudative (wet). In the case of wet age-related macular degeneration, it greatly affects vision loss, and if left untreated, it can lead to blindness.

Unmet Needs
• Non-response or poor-response rate to Anti-VEGF treatment: 40%
• Risk of inflammation, pain, and fear due to intraocular injection
• Non-response or poor-response rate to Anti-VEGF treatment: 40%
- • Risk of inflammation, pain, and fear due to intraocular injection
Mechanism of Action
Signals that reduce permeability • Generally, act through three small GTPases, Rap1, Rac1 and Cdc42 | RhoA/Rock activation is common in leading to stress fiber formation • Reactive oxygen species generated by ECs, MΦ, and PMNs and cytosolic Ca2+ |
