Varenicline solution nasal spray, developed by JIXING’s partner Oyster Point Pharma, is a highly selective cholinergic agonist indicated for the treatment of the signs and symptoms of dry eye disease as a preservative-free nasal spray. Varenicline solution nasal spray is designed to activate the trigeminal parasympathetic pathway to increase the production of natural tears. JIXING has the exclusive rights to develop and commercialize this product in Greater China. In October 2021, varenicline solution nasal spray was approved by the U.S. Food and Drug Administration (FDA) for the treatment of the signs and symptoms of dry eye disease. It is the first and only nasal spray approved by the FDA for the treatment of the signs and symptoms of dry eye disease. In February 2023, varenicline solution nasal spray was approved in Macau SAR. In July 2023, the New Drug Application (NDA) for varenicline solution nasal spray in China was accepted by the National Medical Products Administration (NMPA). 

Additional information

Dry eye disease is a chronic condition that is estimated to impact more than 200 million patients in China and is growing in prevalence, significantly influencing a person’s day-to-day quality of life. 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. 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. Despite the large prevalence and a significant disease burden, there remains a large unmet need in dry eye disease.

Varenicline solution nasal spray (US brand name TYRVAYA® )  is a highly selective cholinergic agonist that is U.S. FDA approved to treat signs and symptoms of dry eye disease as a multidose nasal spray. The parasympathetic nervous system controls tear film homeostasis partially via the trigeminal nerve, which is accessible within the nose. The efficacy of varenicline solution 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.
