Emerging Therapeutics for Dry Eye Syndrome seek to hit the bull’s eye

16 Mar Emerging Therapeutics for Dry Eye Syndrome seek to hit the bull’s eye

Dry Eye Syndrome is characterized by the inability to produce sufficient amount or quality of tears which leads to lack of lubrication and nourishment to the surface of the eye and manifests as chronic eye irritation, inflammation and damage to the surface. There are over 16 million diagnosed cases of dry eye syndrome in the U.S alone.

Dry eye leads to discomfort and pain and can greatly impact the quality of life by making it difficult to perform everyday functions such as reading, driving, using computers and performing daily activities. In the U.S, the financial implications of dry eye management was estimated to be US$11,302 per patient and US$55 billion overall according to a report.

There is no cure for dry eye disease currently and treatment options include topical medication, punctal plugs, practitioner visits, and nutritional supplements, these options are highly inadequate and hence the need for novel solutions. The prevalence of dry eye ranged from 5 to 30 % of individuals aged over 50 according to an estimate by The Epidemiology Subcommittee of the 2007 DEWS.

A report by Transparency Market Research projects that the industry will be worth $7,780 million by 2025 growing at a CAGR of 4.5%. A rising geriatric population, coupled with increased screen exposure, diabetes, environmental factors such as pollution and refractive surgeries are leading to a rise in the incidences of dry eyes, while the lack of adequate therapeutic options, expensive medication along with lack of patient adherence is a challenge for the growth of the market.

However, the market is poised for change with some novel technologies and drug candidates being developed for the treatment of this chronic disorder. We take a look at some promising therapeutics in the offing.

It seeks to leverage its understanding of Reactive Aldehyde Species (RASP) levels to tackle intracellular inflammatory factors including NF-kB, a prominent protein in the inflammatory response. Its reproxalap can bind to free aldehydes triggering a covalent reproxalap-aldehyde adducts that can degrade intracellularly within hours with significant lowering of aldehyde levels. The company plans to initiate part 1 of its Phase 3 clinical trials names RENEW in the first half of 2019 to test the efficacy of reproxalap ophthalmic solution (0.25%) in treatment of ocular dryness, and fluorescein nasal region staining.

In the pipeline are drug candidates ADX-1612 for Mesothelioma, PTLD and Ovarian cancer, ADX-
629 and ADX-1615 for autoimmune disorders that are undergoing clinical trials. The company has acquired Helio Vision for its Phase 3 ready ADX-2191, for proliferative vitreoretinopathy (PVR). ADX-2191 has received Orphan Drug Designation from the U.S. Food and Drug Administration for the prevention of PVR and the company intends to launch phase 3 clinical trials during second half of 2019.

It is developing an investigational drug voclosporin to be used as a topical ophthalmic solution for the treatment of dry eye disease. In addition, the company is also looking at using voclosporin for the treatment of lupus nephritis (LN) and focal segmental glomerularsclerosis (FSGS). Voclosporin’s unique binding action induces structural changes in calcineurin and increases immunosuppressive activity. It is a best-in-class calcineurin inhibitors (CNI) with a dual mechanism of action that can not only block IL-2 expression and T-cell mediated immune responses but also stabilizes the podocyte in the kidney.

Volcosporin has shown to be more effective than conventional calcineurin inhibitors (CNI) by demonstrating a more stable pharmacokinetic and pharmacodynamic interplay and improved metabolic profiles. It is currently recruiting patients for a phase II study of the ocular tolerability of VOS in dry eye syndrome patients.

The company has received a shot in the arm as the USPTO has granted a notice of allowance to the company for patenting voclosporin’s method of use and dosing protocol for Lupus Nephritis (LN) under U.S. patent application 15/835,219, entitled “PROTOCOL FOR TREATMENT OF LUPUS NEPHRITIS”. This could enable the company to stave off competition from generics at least until 2037.
