Retinal diseases 

Retinal diseases, such as diabetic retinal disease (DRD) and age-related macular degeneration (AMD) are a leading cause of irreversible vision loss worldwide, affecting millions of people and often stripping away their independence and quality of life. We believe that behind these statistics are real lives waiting for a better path forward. We are dedicated to changing this narrative by moving beyond current standards to provide accessible, non-invasive, and sustainable solutions that restore the gift of sight to patients and their families.

Diabetic Retinal Diseases

DRD is a common cause of vision loss among diabetic patients. Non-proliferative diabetic retinopathy (NPDR) is the early stage of DR during which patients exhibit no obvious symptoms to mild symptoms such as weakened blood vessels. Chronically elevated blood glucose in diabetes can render tiny blood vessels in the eye "leaky", causing fluid to build up in light-sensing tissue called the retina. This phenomenon, known as edema, can greatly affect the central vision when occurs at the region of the retina known as the macula, which is responsible for sharp, color vision. Diabetic Macular Edema (DME) is the most common cause of vision loss in the DR population. The more advanced stage of DR, known as proliferative diabetic retinopathy (PDR), is characterized by abnormal blood vessel growth (i.e. neovascularization). Abnormal vessel function and growth may contribute to retinal inflammation, ischemia (i.e. inadequate blood flow), and neuronal cell death, all of which can ultimately lead to substantial vision loss or complete blindness.

Treatment Options

DRD may be present without clinically meaningful observations or changes in vision. 

Lifestyle changes are the only options at this stage, and
no therapy exists yet to delay or prevent DRD progression. 

  • Intraocular injections 

  • Laser photo-coagulation

  • Vitrectomy

We aim to transform retinal care 

We are developing a potentially first-in-class, purpose-designed PPAR-alpha agonist to provide a sustainable, disease-modifying oral therapy for DRD. Our mission is to move beyond the limitations of current care, protecting vision and restoring long-term independence to patients worldwide.
