Ophthalmic Disease and Beyond

Oyster Point Pharma is committed to the discovery and development of first-in-class therapies to treat ophthalmic diseases.

Leveraging our nicotinic acetylcholine receptor (nAChR) domain expertise, we are focused on the development of OC-01 (varenicline) nasal spray for the treatment of signs and symptoms of dry eye disease, as well as a number of potential indications and uses associated with and beyond dry eye disease. These include neurotrophic keratopathy, dry eye associated with contact lens intolerance, and ocular surface preparation for refractive surgeries.

Oyster Point’s proprietary, investigational Enriched Tear Film (ETF™) Gene Therapy is being developed for the treatment of select ocular surface diseases. Oyster Point Pharma’s investigational ETF™ Gene Therapy has been shown in preclinical models to deliver target genes to cells using adeno-associated virus (AAV) vectors, nonreplicating DNA delivery vehicles that are currently not known to cause disease. In preclinical models, it has been shown that the protein-producing machinery in the lacrimal gland can be harnessed to secrete selected proteins in the body’s own natural tear film to potentially treat diseases of the ocular surface. We believe that this approach has the potential to change the way that chronic diseases of the ocular surface are treated. Additionally, in preclinical models, it has been shown that OC-01 (varenicline) nasal spray may have the potential to modulate the amount of selected proteins, peptides, antibodies, hormones, enzymes or cytokines secreted from the lacrimal gland into the tear film and onto the ocular surface. We believe that targeting the parasympathetic nervous system through the use of cholinergic agonists, such as OC-01 (varenicline) nasal spray, administered locally in the nasal cavity has the potential to treat a wide range of diseases and disorders.

Oyster Point has partnered in a research collaboration to develop potentially novel therapies to treat bacterial infections in ophthalmology using bacteriophages. Bacteriophages, also known as “phages,” are viruses that are found in the natural environment that infect and replicate specifically in bacteria. Antibiotics normally kill the vast majority of bacteria they encounter, although occasionally a few microbes survive, reproduce, and pass on their immunity to future generations. Over time, certain strains of bacteria can become largely or completely impervious to even the strongest antibiotics. Without effective antibiotics, common procedures and operations, including those for ophthalmology may involve increased risk of infection. As an ocular surface disease company we are committed to developing treatments for the bacteria associated diseases of today and in the future.

Oyster Point has pioneered the administration of selective cholinergic agonist nasal sprays to activate the parasympathetic pathway and stimulate natural tear production, as show in preclinical and clinical studies. We are focused on the development of OC-01 (varenicline) nasal spray for the treatment of signs and symptoms of dry eye disease, as well as a number of potential indications and uses associated with and beyond dry eye disease. These include neurotrophic keratopathy (NK), dry eye associated with contact lens intolerance, and ocular surface preparation for refractive surgeries. We believe that targeting the parasympathetic nervous system through the use of locally administered selective cholinergic agonists, such as OC-01 (varenicline) nasal spray, has the potential to treat a wide range of diseases and disorders.

OC-01 (varenicline) nasal spray is an investigational new drug and has not been approved for any use in any country. The safety and efficacy of OC-01 (varenicline) nasal have not been established.

Adeno-associated virus (AAV) vectors are nonreplicating DNA delivery vehicles that are currently not known to cause disease.

OC-101 (AAV-NGF)
OC-101 (AAV-NGF) is Oyster Point’s investigational gene therapy in development as part of Oyster Point’s proprietary development approach of leveraging Enriched Tear Film (ETF™) Gene Therapy to treat select ocular surface diseases. OC-101 is an AAV containing the nerve growth factor (NGF) gene. NGF is a naturally occurring protein secreted by cells on the surface of the cornea and involved in the differentiation and maintenance of neurons that has been shown to heal the corneal epithelium and improve corneal sensitivity1. Once administered to the lacrimal gland, OC-101 (AAV-NGF) has been shown in preclinical studies to harness the body’s protein-producing machinery to produce NGF, which was then secreted into the tear film and onto the ocular surface.

OC-101 (AAV-NGF) is an investigational gene therapy that has not been tested in humans and has not been approved for any use in any country. The safety and efficacy of OC-101 (AAV-NGF) have not been established.

Oyster Point has partnered in a research collaboration to develop potentially novel therapies to treat bacterial infections in ophthalmology using bacteriophages. Bacteriophages, also known as “phages,” are viruses that are found in the natural environment that infect and replicate specifically in bacteria. Interestingly, bacteriophages collectively constitute a majority of organisms found on planet earth. Bacteriophages are generally safe to humans and are targeted in their ability to infect specific strains of bacteria. Once a bacteriophage attaches to a susceptible bacterium it causes the host cell to die, releasing new bacteriophage to infect other bacteria, thus increasing the dose at the site of the disease.
