Next gen aldehyde traps are at preclinical stage with a novel validated lead and a series of patentably distinct analogs. The entire drug series has freedom to operate and strong IP with composition of matter and methods of use claims.
Platform drugs have multiple options for clinical development, by definition. Depending on the priorities of corporate partners or investors, Oculogics can advance lead compounds to the clinic in oral or topical formulations within two years of M&A or equity funding. Each clinical program can have its own financial exit with exclusive rights to one or more novel and proprietary compounds in this series.

Diseases associated with chronic inflammation cause lifetime disabilities and over 50% of global deaths (1). As an inflammation platform drug, aldehyde traps have the potential to become a safe and potent standard of care in any of these diseases. These include cardiovascular disease, type 2 diabetes and metabolic syndrome, chronic kidney disease, all forms of neurodegenerative disease, and orphan diseases associated with gene defects in reducing enzymes or aldehyde transporters.

A UCSF study led by a Nobel laureate demonstrated that lipid aldehydes irreversibly activate the TRPA1 ion channels that initiate pain signaling in peripheral and spinal nerves (2) and also alter the activity of other pain signaling proteins (3). These findings make chronic pain a promising treatment area for aldehyde traps, consistent with the rapid pain relief reported by patients with a painful condition of ocular inflammation in clinical studies of reproxalap (4), a topical first gen trap. The high potency, oral availability and CNS exposure of next gen traps will provide even greater pain relief. Traps provide non-opioid analgesia with no risk of addiction (5), and unlike drugs that block ion channels, will not impair pain sensitivity elsewhere in the body because they target free aldehydes, not proteins.

Abca4 retinopathies such as dry AMD and Stargardt disease are a special case where aldehyde traps have an additional target: toxic vitamin A dimers called A2E that trigger chronic inflammation (1-3). As A2E accumulates, it causes recurring injuries in retinal pigment epithelial (RPE) cells that provide essential metabolic support to retinal neurons. Systemic treatment with aldehyde traps have preclinical proof of concept in Abca4 knockout mice, where systemic aldehyde trap therapy reduced A2E formation by over 70% (4). In parallel, traps also deactivate lipid and oxysterol aldehydes whose chemical damage promotes lysosome failure, mitochondrial dysregulation, cholesterol accumulation and cell trafficking deficits in RPE, and complement activation causing retinal lesions in late stage disease (5). The high oral availability and CNS exposure of next gen traps allows for treatment by safe oral dosing instead of monthly ocular injections.
Ocular injections of complement inhibitors are an approved treatment for geographic atrophy in late stage dry AMD. This slows the formation of late stage lesions by ~20%, but does not slow the progression of early and middle stage disease when vision can still be saved. In contrast, aldehyde traps are designed to slow progression at all stages by blocking the chemical damage and cellular injuries that activate complement. Neither treatment precludes the other. Combination therapy of oral traps plus complement inhibitor injections could be an option for patients with late stage disease.
