Development Milestones Enrollment Completed in the OLYMPIA Phase 2 Clinical Trial for Stage 1 Neurotrophic Keratopathy (NK), with Data Readout Expected in Q1’23: In October 2022, the Company completed enrollment of patients in the OLYMPIA Phase 2 clinical trial of OC-01 (varenicline solution) nasal spray for the treatment of Stage 1 NK, with a data readout expected in the first quarter of 2023. Total enrollment in the study was 113 subjects at 34 U.S. centers, slightly more than the original target of 100 subjects. In the OLYMPIA Phase 2 clinical trial, OC-01 (varenicline solution) nasal spray is administered three times daily and will be compared to placebo (vehicle) nasal spray. The pre-specified primary endpoint of the trial is the mean change from baseline in corneal fluorescein staining in subjects with Stage 1 NK at Day 56.Positive Pre-IND Meeting Feedback from the FDA to Advance Enriched Tear Film (ETF™) Gene Therapy Towards Clinical Studies for Stages 2 and 3 Neurotrophic Keratopathy: In Q3’22, the Company received positive pre-IND meeting feedback from the U.S. FDA for the proprietary ETFTM gene therapy candidate, OC-101 (AAV-NGF), which is administered as a single, intralacrimal gland injection of an adeno-associated virus (AAV) vector containing the human nerve growth factor (NGF) gene for Stages 2 and 3 NK patients. The Company will commence IND-enabling studies in order to advance the program into clinical studies. During the third quarter of 2022, the Company also disclosed an additional target and further indications for its ETF gene therapy program. Pre-clinical studies are underway with an AAV vector containing diamine oxidase (DAO), a key enzyme involved in histamine degradation, for the treatment of Atopic Keratoconjunctivitis (AKC) and Vernal Keratoconjunctivitis (VKC).

About TYRVAYA® (varenicline solution) Nasal Spray TYRVAYA (varenicline solution) Nasal Spray 0.03 mg is a highly selective cholinergic agonist that is FDA-approved to treat the signs and symptoms of dry eye disease as a multidose nasal spray. The parasympathetic nervous system, the "rest and digest" system of the body, controls tear film homeostasis partially via the trigeminal nerve, which is accessible within the nose. The efficacy of TYRVAYA Nasal Spray in dry eye disease is believed to be the result of varenicline's activity at heteromeric sub-type(s) of the nicotinic acetylcholine (nACh) receptor where its binding produces agonist activity and activates the trigeminal parasympathetic pathway resulting in increased production of basal tear film as a treatment for dry eye disease. Varenicline binds with high affinity and selectivity at human α4β2, α4α6β2, α3β4, α3α5β4 and α7 neuronal nicotinic acetylcholine receptors. The exact mechanism of action is unknown at this time. TYRVAYA® Important Safety Information The most common adverse reaction reported in 82% of patients was sneezing. Events that were reported in 5-16% of patients were cough, throat irritation, and instillation-site (nose) irritation. There are no contraindications associated with TYRVAYA (varenicline solution) Nasal Spray. Please see full Prescribing Information at www.tyrvaya-pro.com/prescribinginformation. About Dry Eye Disease and the Role of Tear Film Dry eye disease is a chronic condition that impacts an estimated 38 million people in the U.S. and is growing in prevalence.1,2 It can cause persistent stinging, scratching, burning sensations, sensitivity to light, blurred vision, and eye fatigue. Dry eye disease is a multifactorial disease of the ocular surface characterized by disruption of the tear film. Human tear film is a complex mixture of more than 1,500 different proteins, including growth factors and antibodies, as well as numerous classes of lipids and mucins.3 Natural tear film protects and lubricates the eyes, washes away foreign particles, contains growth factors and antimicrobial components, and creates a smooth surface that forms the primary refractive surface of the eye.

Eye specialist Oyster Point Pharma announced Monday that it is being acquired by Viatris Inc. after Oyster’s board of directors unanimously signed off on the deal. Under the acquisition offer, Viatris will purchase all outstanding Oyster Point shares at $11.00 per share, to be paid in cash at the deal’s closing. The agreement also includes a contingent value right for additional cash payments of up to $2.00 per share upon achieving specific performance targets in 2022. In particular, Oyster Point’s shareholders will get $1.00 more per share if the New Jersey biotech generates at least $21.6 million net revenue of Tyrvaya (varenicline solution). This add-on increases to $2.00 per share if net revenues reach $24.0 million. The companies expect to close the transaction early next year. In a statement, Jeffrey Nau, Ph.D., MMS, president and chief executive officer of Oyster Point, said the acquisition agreement will bring together his company’s portfolio and industry expertise with Viatris’ global scale and capabilities to “meaningfully shape the future of eye care, to the benefit of patients.” After the deal has been closed, Viatris will then move to acquire all remaining shares of Oyster Point that were not tendered into the buyout offer. This second-step merger will have the same per-share price of $11.00, along with the $2.00 CVR. A Promising Portfolio The buyout will grant Viatris access to Oyster Point’s Tyrvaya, a therapeutic nasal spray approved by the FDA in October 2021. Tyrvaya is the first and only FDA-approved nasal spray for dry eye in the U.S. Tyrvaya is a highly selective cholinergic agonist that mimics the action of the neurotransmitter acetylcholine to activate the parasympathetic nervous system, promoting the production of the basal tear film and ultimately easing dry eye symptoms. Varenicline, the drug’s active component, can engage the nicotinic acetylcholine receptor on the trigeminal nerve, which is accessible through the nose. In June, before the drug’s launch, Oyster Point cut off some 50 employees to “prioritize launch expenses for Tyrvaya and its field-based sales resources,” Nau said. The job cuts were concentrated in general and administrative roles, and the company continued to allocate some 150 to 200 field-based sales personnel to drive the product launch. Nau added that the company believes this will reduce the total operating expenses and continue to drive the Tyrvaya launch forward. Aside from the dry eye nasal spray, Oyster Point will also hand over a healthy pipeline of ophthalmic therapies. This includes OC-01, another nasal spray formulation of a varenicline solution, currently under Phase II assessments for stage I neurotrophic keratopathy. Results are expected later this year. The pipeline also involves two gene therapies: OC-101 AAV-NGF for stage 2 and 3 neurotrophic keratopathy and OC-103 AAV-DAO for vernal or atopic keratoconjunctivitis. Both are intravitreally injected and are scheduled for pre-investigational new drug meetings within the year.
