Harrow Acquires Global Rights to TYRVAYA®, the First and Only FDA-Approved Nasal Spray for Dry Eye Disease

NASHVILLE, Tenn., Aug. 06, 2026 (GLOBE NEWSWIRE) -- Harrow (Nasdaq: HROW), a leading provider of ophthalmic disease management solutions in North America, today announced that it has entered into a definitive agreement to acquire TYRVAYA® (varenicline solution) nasal spray 0.03 mg from Viatris Inc., a global healthcare company. TYRVAYA is a cholinergic agonist indicated for the treatment of the signs and symptoms of dry eye disease (DED) and is currently approved in the U.S., China, and Taiwan, with marketing authorization applications pending in other countries.

This acquisition expands Harrow’s dry eye portfolio, complementing the Company's flagship VEVYE franchise by addressing dry eye disease with a different underlying mechanism of action. Together, VEVYE and TYRVAYA enable Harrow to provide physicians with a broader range of differentiated treatment options while addressing the diverse needs of patients with dry eye disease. Because TYRVAYA is delivered as a nasal spray rather than an eye drop, it avoids ocular instillation-site reactions entirely; its prescribing information includes no contraindications and no warnings or precautions, and its most common adverse reaction, sneezing, is transient. Drop-free DED management is a meaningful differentiator for patients who struggle with or cannot tolerate topical drops, including those who experience burning, stinging, or other ocular adverse reactions associated with eye drops. The acquisition also leverages Harrow's sales, marketing, market access, medical affairs, and reimbursement infrastructure and is expected to further strengthen the Company through the addition of select talent from Viatris.
