PRINCETON, N.J., and SHANGHAI, China, Aug. 05, 2021 (GLOBE NEWSWIRE) —  Oyster Point Pharma, Inc. (Nasdaq: OYST), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of first-in-class pharmaceutical therapies to treat ophthalmic diseases, today announced an exclusive license and collaboration agreement with Ji Xing Pharmaceuticals (Ji Xing) to develop and commercialize OC-01 (varenicline) and OC-02 (simpinicline) nasal sprays for the treatment of signs and symptoms of dry eye disease for patients in Greater China. Ji Xing is a biotechnology company headquartered in Shanghai and founded by RTW Investments, LP (RTW), focused on bringing breakthrough medicines to underserved Chinese patients with refractory, serious and life-threatening diseases.

“This agreement marks an important step toward providing OC-01 (varenicline) and OC-02 (simpinicline) nasal sprays to patients living with dry eye disease globally while strengthening our cash position,” said Jeffrey Nau, president and chief executive officer of Oyster Point Pharma. “We look forward to partnering with the team at Ji Xing to develop and potentially commercialize these novel therapies in the licensed regions.”

“Stimulating natural tear film production may be a paradigm-changing way to treat dry eye disease, which affects more than 150 million patients in China,” said Joseph Romanelli, CEO of Ji Xing. “We are excited to partner with the Oyster Point team, who are innovative pioneers focused on developing therapeutics for ophthalmic diseases, and bring both OC-01 and OC-02 to China. OC-01 and OC-02 have the potential to offer a compelling alternative to artificial tears and anti-inflammation eye-drops to help ease the disease burden for patients.”

Under the terms of the agreement, Oyster Point will grant Ji Xing an exclusive license to develop and commercialize both OC-01 (varenicline) and OC-02 (simpinicline) in patients with ophthalmic diseases in Greater China. Oyster Point will receive an upfront payment consisting of $17.5 million in cash and up to 0.75% of shares in Ji Xing, half of which is subject to a pre-specified vesting condition. In addition, Oyster Point is eligible to receive up to $204.8 million in milestone payments and tiered royalties based on future net sales of OC-01 and OC-02 in Greater China. Ji Xing intends to manufacture OC-01 and OC-02 locally in China and will be responsible for development and commercialization costs in its licensed territory.

About Dry Eye Disease

Dry eye disease is a chronic, progressive condition that impacts more than 30 million people in the United States and over 150 million people in China. An estimated 16 million adults in the U.S. have been diagnosed with dry eye disease, a multifactorial condition of the ocular surface characterized by disruption of the tear film. A healthy tear film protects and lubricates the eyes, washes away foreign particles, contains growth factors and antimicrobial components to reduce the risk of infection, and creates a smooth surface that contributes refractive power for clear vision. Dry eye disease can have a significant impact on a person’s day-to-day quality of life, as it can cause persistent stinging, scratching, burning sensations, sensitivity to light, blurred vision and eye fatigue. Despite the large prevalence of dry eye and the burden of the disease, there remains a significant unmet need for effective therapies.

About OC-01 (varenicline) Nasal Spray

OC-01 (varenicline) nasal spray is a highly selective cholinergic agonist being developed as a multidose preservative-free nasal spray to treat the signs and symptoms of dry eye disease and neurotrophic keratopathy. 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. Administered as a preservative-free, aqueous nasal spray, in pre-clinical and clinical studies, OC-01 (varenicline) nasal spray was shown to have a novel mechanism of action with activation of the trigeminal parasympathetic pathway in the nasal cavity to activate natural tear film production. The 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. This complex tear film is responsible for forming the primary refracting surface of the eye, as well as protecting and moisturizing the cornea. In December 2020, Oyster Point submitted to the U.S. Food and Drug Administration (FDA) a New Drug Application (NDA) for OC-01 (varenicline) nasal spray for the treatment of signs and symptoms of dry eye disease. The Prescription Drug User Fee Act (PDUFA) target action date is October 17, 2021, with a planned U.S. launch of OC-01 (varenicline) nasal spray in this indication in the fourth quarter of 2021, if approved by the FDA. 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 spray have not been established.

About OC-02 (simpinicline) Nasal Spray

OC-02 (simpinicline) nasal spray is a highly selective cholinergic agonist. Simpinicline citrate is a strong nicotinic acetylcholine receptor agonist of activity at the α4β2, α3β4, α3α5β4, and α4α6β2 receptors and weak agonist activity at the α7 receptor. OC-02 has been previously studied in two Phase 2b clinical trials for dry eye disease.
