Oyster Point Pharma Announces Publication in Ophthalmology of ONSET-2 Phase 3 Data on TYRVAYAᵀᴹ (varenicline solution) Nasal Spray
PRINCETON, N.J., Nov. 15, 2021 (GLOBE NEWSWIRE) -- Oyster Point Pharma, Inc. (Nasdaq: OYST), ("Oyster Point Pharma" or "the Company") a commercial-stage biopharmaceutical company focused on the discovery, development and commercialization of first-in-class pharmaceutical therapies to treat ophthalmic diseases, today announced that results from the multicenter, randomized, double-masked, vehicle-controlled Phase 3 clinical trial (The ONSET-2 study) of TYRVAYATM Nasal Spray (varenicline solution) have been published in Ophthalmology.1 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.
“This Phase 3 study of TYRVAYA nasal spray shows consistent outcomes as compared to the ONSET-1 Phase 2b trial. These results show clinically meaningful improvements in basal tear film production,” said Jeffrey Nau, Ph.D., MMS, President and Chief Executive Officer of Oyster Point Pharma. Dr. Nau continued, "These results are notable as TYRVAYA is the first and only cholinergic agonist nasal spray approved by the FDA to treat patients with the signs and symptoms of dry eye disease, leveraging this novel mechanism of action of activating the trigeminal parasympathetic pathway.”
About ONSET-2 Study
The ONSET-2 Phase 3 pivotal clinical study was a multicenter, randomized, double-masked, vehicle-controlled trial in adult subjects at least 22 years of age with dry eye disease in the U.S. The main eligibility criteria for the studies included a physician’s diagnosis of dry eye disease, a baseline Schirmer’s Score of <10 mm. Patients could have an Eye Dryness Score from 0-100 mm (visual analog scale). TYRVAYA™ Nasal Spray was administered as a single spray into each nostril twice-daily. The primary and key secondary endpoints, including improvement in Schirmer’s Score and Eye Dryness Score (EDS) as compared to vehicle control, were measured at Day 28. The ONSET-2 study of TRYVAYA Nasal Spray enrolled a broad population of mild, moderate, and severe dry eye disease subjects, as measured by Eye Dryness Score at baseline (range 2-100 mm).
About TYRVAYA™ (varenicline solution) Nasal Spray
TYRVAYA (varenicline solution) Nasal Spray 0.03 mg (formerly referred to as OC-01) 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. 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.

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.2,3 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.4 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.
